UNDERVOLTAGE RELAY SETPOINTS Revision Summary DC-OYIY Vol I DCD 1 Rev. 0 Page 2 This revision removes the various load flow and motor starting calculations from this calculation.

Calculations necessary to serve as boundary conditions for the various setpoints are now contained in Calculation DC-6447 (Ref. 8.2.14). Several attachments and appendices that are out of date or no longer applicable to this calculation have been removed. Tables 1 through 4 and Figures 1 through 3 have been removed because DC-6447 (Ref. 8.2.14) now provides the equivalent information.

This revision addresses the replacement of the Reactor Building 4160 V bus degraded voltage relays by EDP-35621 Rev. A (Ref. 8.2.18). In addition it applies the DECO File Cl-4180 (Ref. 8.2.1) to the determination of uncertainties, setpoints and allowable values for tKe relay settings.

This revision also revises the setpoint for the LPCI swing bus undervoltage relays based on Calculations DC-6447 (Ref. 8.2.14) and DC-S003 (Ref. 8.2.36).

UNDERVOLTAGE RELAY SETPOINTS

1.0 Purpose

and Objectives Purpose DC-0919 Vol I DCD 1 Rev. 0 Page 5 The primary purpose of this design calculation is to determine the undervoltage (UV) relay trip settings for plant safety-related buses for both Primary (Loss of Voltage, LOV) and Secondary (Degraded Voltage, DV) levels. Both safety Divisions of the Fermi 2 electrical system are analyzed to determine the Primary and Secondary undervoltage setpoints.

The determination of the setpoints and associated reset values are based on meeting the requirements ofPSB-l (Ref 8.2.21) as it is applied to Fermi 2. NRC-Branch Technical Position PSB-l (Ref. 8.2.21) "Adequacy of Station Electric Distribution System Voltages" reconfirms the requirements for degraded grid and loss of off-site power relaying.

The loss of voltage and degraded voltage relay settings are also required for the Technical Specifications Table 3.3.8.1-1.

Objective The objective of the undervoltage scheme is to sense and respond to off-site voltage variations which affect the Fermi 2 auxiliary systems. The undervoltage schemes specifically address the loss of off-site power system voltage and voltage degradation of the off-site and on-site power system. Two undervoltage schemes are employed on each Division to accomplish these objectives.

The two undervoltage schemes are the primary for loss of off-site power (loss of voltage) and the secondary for degraded voltage levels. Operation of either scheme automatically isolates the associated divisional bus from the grid, sheds bus loads to prevent overloading the emergency diesel generators (EDG), and initiates both EDG and load sequencer start. NRC requirements are contained in Item 222.31A (Appendix A) which Fermi 2 has committed to implement.

• The upper AV and upper ALim are not determined per the standard methodology ofCI-4180 (Ref. 8.2.1), since it does not include the case of an upper limit for a descending actuation.

The upper A V and ALim are determined as required to support the voltage analysis (Ref. 8.2.14). The upper AV is set at the maximum error above the NTSP, and represents the maximum expected actuation of the decreasing voltage trip. The upper ALim must be equal to or greater than the reset point of the upper A V. ** Min SetPt that maintains required uncertainty between the Lower ALim and NTSP. New relay Operate NTSP and new lower Allowable Value have been determined to be separated from the lower Analytical Limit by the required channel uncertainty per DECO File CI-4180 (Ref. 8.2.1). The new relay Operate NTSP is greater than the minimum possible setpoint required for the lower ALim. The upper A V is set at the maximum possible setpoint actuation above the NTSP, by adding the entire channel error to the NTSP. The maximum possible reset point is the highest value at which reset could occur if the relay Operates at the Upper A V (max setpoint).

The maximum possible reset point is bounded by the Upper ALim. The Technical Specifications in Table 3.3.8.1-1 must be revised to incorporate the new Allowable Values.

3.0 Methodology

for Primary and Secondary (Degraded)

Setpoints

3.1 Calculation

Methodology DC-0919 Vol I DCD 1 Rev. 0 Page 19 The calculation methodology from DECO File CI-4180 (Ref. 8.2.1) is used to determine the instrument accuracies and setpoints.

Per this methodology, the relationship between the nominal trip setpoint (NTSP), Allowable Value (A V) and Analytical Limit (ALim) is defined in DECO File C 1-4180 Part III, Sections 10.a and 10.b, as: Ascending Process: AV:::; ALim -(1.64512)*(LAT 2 + LC 2 + PMA 2 + PEA2)1/2 +/- Bias NTSP:::; ALim -(1.645/2)*(LAT 2 + LC 2 + PMA 2 + PEA 2 + LDA2)1/2 +/- Bias Descending Process: AV 2:: ALim + (1.645/2)*(LAT 2 + LC 2 + PMA 2 + PEA2)1/2 +/- Bias NTSP 2:: ALim + (1.645/2)*(LAT 2 + LC 2 + PMA 2 + PEA 2 + LDA2)1/2 +/- Bias See Section 6.0 for definitions of terms 3.2 Specific Methodology for Determination of Two Sided Allowable Values The undervoltage relays are a unique case in the Technical Specifications, in that they have both an upper and a lower Allowable Value for a decreasing voltage setpoint, and an upper and a lower Allowable Value for an increasing time setpoint.

Thus the DECO File CI-4180 (Ref. 8.2.1) methodology shown above is expanded to take this into account. Loss of Voltage UV Relay (27D) Voltage Settings:

For the Loss of Voltage UV relay voltage AVs, the Technical Specification AVs are specified in Table 3.3.8.1-1 for a decreasing voltage setpoint, so the existing lower A V (A VL) is analyzed for acceptability using the standard formulas for a descending process as stated in Section 3.1. The existing A VL is used to compute a maximum lower analytical limit. This computed lower analytical limit is then used to compute a minimum NTSP using the standard formula for a descending process from Section 3.1. If the NTSP is equal to or greater than the minimum NTSP, then the NTSP is acceptable with respect to the lower ALim. This method is expanded to address the upper A V (A VU) and analytical limit by applying the same formulas described in Section 3.1 above as though it were an ascending process trip. The minimum upper analytical Limit is computed by adding the combination of the non-drift errors to the existing AVU. Then the computed upper analytical limit is used to compute a maximum NTSP by subtracting the combination of all errors from the upper analytical limit. If the NTSP is equal to or less than the maximum NTSP, then the NTSP is acceptable with respect to the upper ALim.

UNDERVOLTAGE RELAY SETPOINTS Loss-of-Voltage UV Relay (27m Time Settings:

DC-0919 Vol I DCD 1 Rev. 0 Page 20 For the Loss of Voltage UV relay time AVs, the Technical Specification AVs are specified for an increasing time setpoint, so the existing upper A V (A VU) is analyzed for acceptability using the standard formulas for an ascending process as stated in Section 3.1. The existing A VU is used to compute a minimum upper analytical limit. This computed upper analytical limit is then used to compute a maximum NTSP using the standard formula for an ascending process from Section 3.1. If the NTSP is equal to or less than the maximum NTSP, then the NTSP is acceptable with respect to the upper ALim. This method is expanded to address the lower AV (AVL) and analytical limit by applying the same formulas described in Section 3.1 above as though it were a descending process trip. The maximum lower analytical limit is computed by subtracting the combination of the non-drift errors from the existing AVL. Then the computed lower analytical limit is used to compute a minimum NTSP by adding the combination of all errors to the lower analytical limit. If the NTSP is equal to or greater than the minimum NTSP, then the NTSP is acceptable with respect to the lower ALim. Degraded Voltage UV Relay (27N) Voltage Settings:

This calculation determines new A V sand NTSPs for the degraded voltage UV relay voltages based on the new ALims provided by the voltage analysis (Ref. 8.2.14). Because the Technical Specification Table 3.3.8.1-1 A V s are for a decreasing voltage setpoint, the lower A V (A VL) and minimum NTSP are determined via the standard formulas for a descending process as stated in Section 3.1. The new NTSP is then chosen by rounding up the minimum NTSP. In the case of the degraded voltage relay, the maximum possible reset point must be shown to be within the recovery voltage limits of the voltage analysis (Ref. 8.2.14). Because the reset is 0.5% of setting above the Operate NTSP, this maximum possible Operate NTSP is used to establish the upper AV (AVU) for the decreasing voltage trip. Thus the A VU is set at the NTSP plus the combination of all possible errors. The maximum Reset point is determined by dividing the AVU (max possible Operate NTSP) by 0.995 based on the 0.5% differential between operate and reset voltages.

This maximum possible reset point must be less than or equal to the Upper Analytical Limit, which is the recovery voltage determined in the voltage analysis, (Reference 8.2 .14). Degraded Voltage UV Relay (27N) Time Settings:

The upper Alim for the LOCA time delay supports the 13 second EDG start time from the LOCA analysis (Ref. 8.2.19, UFSAR Tables 6.3-7 & 8.3-5). The EDG start circuit includes a separate time delay relay, and an additional 0.18 seconds is required to account for the closure times of the EDG output and RHR pump motor breakers.

Thus the upper ALim for the DV LOCA time delay is determined by subtracting the maximum EDG start timer delay and 0.18 seconds from the 13 second EDG start time for LOCA. Although the EDG start timer relay is not in the Tech Spec, for conservatism, the standard methodology from CI-4180 (Ref. 8.2.1) is applied to determine the uncertainty of its actuation, and the resultant maximum and minimum time delays. The Technical Specification Table 3.3.8.1-1 A V s for the LOCA condition degraded voltage relays are for an increasing time setpoint, so a new upper A V (A VU) is calculated via the standard formula for an ascending process as stated in Section 3.1. The lower ALim is conservatively chosen to be just above the Core Spray pump acceleration time (Ref. 8.2.14). The new lower AV (AVL) for LOCA conditions is calculated via the formula for a descending process as stated in Section 3.1, so the A VL will be separated from the lower ALim by the combination of all errors except drift. The new LOCA time NTSP is set then determined by setting it halfway between the A VL and A VU. The most restrictive (lowest) NTSP from either Division I or Division II is than applied to both divisions as the new LOCA Operate NTSP.

UNDERVOLTAGE RELAY SETPOINTS DC-0919 Vol I DCD 1 Rev. 0 Page 21 For non-LOCA conditions, the output of the ABB undervoltage relay (set at the LOCA time delay) starts a second Agastat timer relay. Thus the total non-LOCA time delay is the combination of the time delay from the degraded voltage undervoltage ABB relay (set at the LOCA time delay) and the time delay of the Agastat timer relay. The Technical Specification non-LOCA time AVs must be shown to bound the combination of the individual time AVs for the undervoltage relay plus the non-LOCA timer relay. The total NTSP for the non-LOCA time Operate NTSP is the undervoltage relay LOCA time Operate NTSP plus the timer relay Operate NTSP. 3.3 Conversion from 4160V Process Buses to 120V Relay Buses Per References 8.2.25 -8.2.28 there are two types of potential transformers that step down the voltage from the monitored 4160 V bus to the 120V relaying loop. The ratio of the input to output voltages is 42001120 for the Phase to Phase (P-P) type and 24001120 for the Phase to Neutral (P-N) type. Thus when converting specific voltage values from 4160 V to 120 V, 42001120 is used for the P-P relays, and 2400 1120 is used for the P-N relays, because 2400 ;:::; 4160/-V3.

The P-P 42001120 conversion is slightly larger than the (2400*-V3) 1120 conversion, so all error terms are conservatively converted as 42001120.

Both the potential transformers and the relays are located within the switchgear cabinets, so no significant voltage drop is expected between the PT and the relays. 3.4 Methodology Considerations for Coordination between 480V Buses and 4160V Buses The undervoltage relay settings for these buses are set to ensure adequate coordination between the 4160V and 480V buses with respect to time and loss of voltage settings.

Time Coordination The Division 1 and 2 primary loss of voltage time delay (TD) setpoint selection will prevent false operation on normally expected transient disturbances.

The UV device will coordinate with the overcurrent devices. The clearing time for the for the overcurrent device in which a fault depresses bus voltage will be less than the UV time delay. Under normal operating conditions the longest fault clearing time for the faults that will depress the voltage within the operating range of the UV relay are less than one second.

A shorter time delay could cause an inadvertent grid separation due to a primary loss of voltage relay actuation.

Evaluation of the coordination between overcurrent and undervoltage devices is provided in Ref. 8.2.22. Loss of Voltage Coordination The 4160V buses must trip first to prevent isolation of the 480V buses without EDG initiation.

Loss of voltage at the 4160V buses initiates the EDGs. The 480V bus primary UV devices should coordinate with the 4160V primary device. There is typically a 2-3% voltage drop between the 480 and 4160V buses. Therefore to ensure selectivity, all 480V UV relays are set to account for the voltage drop bus difference.

A higher trip setpoint could cause mis-coordination of relays which could lead to an inadvertent 480 volt bus separation due to a primary 480 volt loss of voltage relay actuation (Ref. 8.2.22).

Boundaries and Limitations

4.1 Boundaries

DC-0919 Vol I DCD 1 Rev. 0 Page 22 This calculation involves Divisions I and II safety-related buses only. These buses are specified below: 1. Reactor/Auxiliary Building 4160 Volts buses 64B, 64C, 65E and 65F: The 4160 Volts Reactor Building buses (64B, 64C, 65E and 65F) have primary and secondary (degraded)

UV relays Protection (References 8.2.25 -8.2.28). 2. RHR Building 4160 Volts Buses IlEA, 12EB, l3EC and 14ED: The 4160 Volts RHR building buses (IlEA, 12EB, l3EC, and 14ED) are electrically part of the reactor building buses. The UV schemes for these buses are initiated by the 4160 Volts Reactor building UV schemes and, as such do not require separate UV monitors.

Even so, separate primary UV devices are provided for each bus. 3. Reactor/Auxiliary/

RHR Building 480 Volts Buses nB, nc, nE, nF, nEA, nEB, nEC and nED: Each of the above 4160 Volts buses (64B, 64C, 65E and 65F, IlEA, 12EB, l3EC, and 14ED) feeds one 480 Volts bus. The UV schemes for these 480 Volts buses are initiated by their respective 4160 Volts bus UV scheme and as such do not require separate UV monitors.

Even so, separate primary UV devices are provided for each 480 Volts buses. The 480 Volts buses UV schemes perform the function ofload shedding their respective bus only. 4. Operator action is taken when Divisional bus low voltage alarms ARP 9D22 and ARP IOD43 (References 8.2.29 and 8.2.30, respectively) are received.

If the alarm cannot be corrected with the assistance of the grid operator and voltage further degrades then the operator action is to transfer the impacted Division to the EDGs prior to the trip actuation of the degraded under voltage relay. 4.2 Methodology Limitations None

5.0 Assumptions

DC-0919 Vol I DCD 1 Rev. 0 Page 23 5.1 Unless specifically noted otherwise by the manufacturer, per the methodology of Ref. 8.2.1, calibration equipment accuracies are taken as three (3a) values due to periodic calibration with high accuracy standards traceable to the National Bureau of Standards.

Also per Ref. 8.2.1, the accuracy of the standards is conservatively assumed to be equal to twice the accuracy of the testing equipment, unless otherwise noted. This assumption is verified by conformance to Ref. 8.2.1. Verified Assumption.

5.2 The manufacturer does not state a drift effect for the ABB/ITE relays, mode127D and 27N. Per the Ref. 8.2.1 methodology, when the manufacturer does not state a drift, it can be assumed that the drift is included in the manufacturer's reference accuracy.

In this calculation, for added conservatism, instead of assuming that the drift is included, a separate assumed drift effect of +/-0.5 % of setpoint per refueling outage is applied for channel instrument drift. Attachment V includes multiple surveillances of observed as-left to as-found data for the Type 27D relay. The Type 27N is the high accuracy version of the Type 27, and so it is expected that its performance characteristics (including drift) are equal to or better than those of the 27D. Inspection of the data in this attachment shows that of the 224 cases, only 13 were found greater than 0.5% of setpoint.

Thus 0.5% of setpoint is bounding for over 94% of the observed drift values. The observed drift, or difference in as-left to as-found values includes the combined effect of all uncertainties present during calibration, which are relay repeatability, calibration as-left tolerance, measurement and test equipment accuracy, and actual drift. Because the assumed drift value is applied only as drift, and the other error sources are applied separately within the calculation, it is conservative to assume the 0.5% of setting as a 2a assumed drift value. The inspection of this data in Attachment V provides verification of this assumption.

Verified Assumption.

There are no unverified assumptions.

UNDERVOLTAGE RELAY SETPOINTS DC-0919 Vol I DCD 1 Rev. 0 Page 24 6.0 Definitions of Terms Primary Relaying:

The primary loss of power undervoltage relay setpoints are defined such that anticipated transient voltages must not drop below the relay setpoints.

Setpoints at this level should be selected to prevent false motor starting transient trips. When system transient voltages do fall below the established bus limits then the primary relay will activate and separate the Fermi 4160 V buses from offsite power. Secondary Relaying:

Secondary or Degraded voltage is defined as a level of voltage which is insufficient to operate safety-related loads but not low enough to operate the primary loss of off-site power protection.

While operating at this voltage level is undesirable, analysis indicates that equipment will function without damage while voltage recovery is attempted.

The associated time delays limit the time for the recovery attempt. Primary Under Voltage (UV) Relays: These relays are set to trip on a complete Loss of Voltage. These relays are XY27A, YZ27A, XN27C and YN27C. Reference drawings are 1-2572-28,29 (Ref. 8.2.25,8.2.26) and 1-2578-05,09 (Ref. 8.2.27, 8.2.28). Secondary UV Relays: These relays are set to trip when the offsite voltage has degraded to the point where safety systems should not be operated.

Continued operation under degraded voltage conditions may cause damage to Class IE equipment.

These relays are XY27B, YZ27B, ZN27D and YN27D. Reference drawings are 1-2572-28,29 (Ref. 8.2.25, 8.2.26) and 1-2578-05,09 (Ref. 8.2.27, 8.2.28). Secondary UV Relay (480V buses): A relay which is set to trip when the voltage on 480V swing bus fed from the Emergency Diesel Generator (EDG) has degraded to the point where the LPCI motor operated valves fed from swing bus MCC should not be operated as continued operation may cause damage to the valves. ETAP: Computer program that models the electrical system within Fermi to analyze load flow bus voltages, Load Tap Changer (LTC) performance and motor starting conditions.

Division I: This is the section of the Fermi electrical distribution system that is connected to the 120 kV grid that serves the both safety related and balance of plant loads through SS64. SS64 contains a LTC which will maintain 4160 bus voltages at 100% for the range ofUFSAR voltage limits. Division II: This is the section of the Fermi electrical distribution system that is connected to the 345 kV grid that serves the safety related and balance of plant loads through SS65. SS65 does not have an LTC therefore all grid voltage variations will be transferred and seen on the 4160 bus voltages.

UNDERVOLTAGE RELAY SETPOINTS DC-0919 Vol I DCD 1 Rev. 0 Page 29 Per Reference 8.2.17 (included as Attachment P), the E7012 is physically assembled from the same parts as the non-nuclear qualified 7012. The larger repeat accuracy of 10% reflects the combination of the repeat accuracy and harsh environmental testing. Thus if an E7012 is not subject to the harsh environment, its base repeat accuracy is equal to that of the industrial model 7012 (+/-5% of setting).

100% of the population ofE7012s and 7012s are tested to verify their actuation within specified limits before shipping.

Thus the specified repeat accuracy may be considered a 3a confidence level. 8.1.5 Per Reference 8.2.5, the relays are located in the bus 64B/C and 65EIF switchgear, which are located in the Div I and Div II switchgear rooms. Per Ref. 8.2.6, pages 43 and 47, these are mild environmental zones, but after LOCA with an HV AC failure, these zones may reach a maximum temperature of 120 0 p (49°C). 8.1.6 Based on 8.1.5 above, the E7012s are located in the switchgear room, which is a mild environment, so the +/-5% of setting repeat accuracy of the 7012 will be applied to a 3a confidence level. 8.1.7 Per Ref. 8.2.7 through 8.2.10, the existing relays are calibrated by measuring the voltage with a Fluke 8060A (200Vac range) and the time delay with an SST-9203 Digital Timer. The existing voltage as left tolerance (AL T) for all relays is +/- 0.5 Vac. The existing time as left tolerance (AL T) is +/-0.05 seconds.

Per Reference 8.2.12, the Agilent 34401A accuracy specifications have a 4a confidence level. They will be applied conservatively within this calculation as 3a values.

When the bus voltage decreases to the Operate setpoint, the relay output contacts actuate after a short time delay. The relay output contacts isolate the Class IE buses from the off site source and start the diesel. If the reset point is reached before completion of the time delay, then the relay resets and the output contacts do not change state. For loss of voltage, the loss of voltage undervoltage relay provides the required time delay. For degraded voltage, the degraded voltage relay provides the required time delay for the coincident LOCA case. In the case of degraded voltage without LOCA, after the LOCA time delay is fulfilled, then the actuation of the undervoltage relay contacts will initiate a second timer relay, which actuates after an additional delay. The total non-LOCA time delay is the combination of the LOCA time delay plus the non-LOCA timer relay delay.

Although the bus voltage is monitored at the source, and it would be expected that the actual bus voltage at the relay locations would be lower, it is the range of control power variation (138.5 Vdc -105 Vdc) that is used to determine the control power error effect for the relays (Inputs 8.1.2 and 8.1.3). Thus the control power error effect for the relays is calculated over the 105 to 138.5 V dc range. 8.1.14 Per Reference 8.2.20, the following data is applicable to the Megger SST-9203 digital timer: Range: 0.0001 to 99.9999 seconds Least Significant Digit (LSD): 0.0001 second Accuracy:

UNDERVOLTAGE RELAY SETPOINTS DC-0919 Vol I DCD 1 Rev. 0 Page 37 The table below details the analysis for the Division I Loss of Voltage UV relay voltage AVs. Per the DECO File Cl-4180 (Ref. 8.2.1) methodology the Technical Specification AVs are specified for a decreasing voltage setpoint, so the existing lower AV (AVL) is analyzed for acceptability using the standard formulas for a descending process as stated in Section 3.1. The existing A VL is used to determine a maximum lower analytical limit. This computed lower analytical limit is then used to compute a minimum relay actuation voltage using the standard formula from Section 3.1. The acceptability of the existing A VL and NTSP is then verified by subtracting all the possible sources of error from the existing NTSP and verifying that the result is equal to or greater than the minimum relay actuation voltage based on the computed lower Alim. Although this is a descending process trip, because there is no particular requirement for the upper ALim, the existing upper A V (A VU) is analyzed for acceptability by applying the same process described above for an ascending process trip. The minimum upper ALim is determined by adding the combination of the non-drift errors to the existing AVU. The existing NTSP and upper AV are acceptable if the upper ALim minus the combination of all errors including drift is shown to be greater than the existing NTSP. The basic calculation is done in the 4160V bus voltage values. The 4160V values are converted to the 120V relay values by multiplying by the ratios from Section 3.3, which are 120/4200 for the P-P relay and

UNDERVOLTAGE RELAY SETPOINTS DC-0919 Vol I DCD 1 Rev. 0 Page 40 The table below determines new A V s and NTSPs for the degraded voltage UV relay voltages based on the new ALims provided by reference 8.2.14. Because the Technical Specification AVs are for a decreasing voltage setpoint, the lower AV (AVL) is determined via the standard formula for a descending process as stated in Section 3.1. The upper A V (A VU) is then determined by adding the maximum channel error to the operate NTSP. This will set the AVU at the maximum point at which the decreasing voltage can actuate the relay once all the possible sources of error have been considered.

The maximum Reset point is determined by dividing the AVU (max possible actuation point) by 0.995 based on the desired 0.5% differential between operate and reset voltages.

This maximum possible reset point must be :S the Upper Analytical Limit, which is the upper voltage determined in the voltage analysis, (Reference 8.2.14).

Good practice is to set the ALT equal to the VA when possible, or to use at least one half of the VA. Since the VA is +/-0.731 seconds, the existing +/-0.05 seconds is an order of magnitude too small. Thus it is increased in this analysis to a more realistically achievable

+/-0.5 seconds, and by output of this calculation will be changed in the calibration procedure.

UNDERVOLTAGE RELAY SETPOINTS DC-0919 Vol I DCD 1 Rev. 0 Page 42 The upper Alim for the LOCA time delay supports the 13 second EDG start time from the LOCA analysis (Ref. 8.2.19, UFSAR Tables 6.3-7 & 8.3-5). The EDG start circuit includes a separate time delay relay, and an additional 0.18 seconds is required to account for the closure times of the EDG output and RHR pump motor breakers.

Thus the upper ALim for the DV LOCA time delay is determined by subtracting the maximum EDG start timer delay and 0.18 seconds from the 13 second EDG start time for LOCA. Appendix G contains the determination of error associated with the EDG start timer relay. The Technical Specification A V s for the LOCA condition degraded voltage relays are for an increasing time setpoint, so a new upper A V (A VU) is calculated via the standard formula for an ascending process as stated in Section 3.1. The lower ALim is conservatively chosen as 5.50 seconds to be greater than the Core Spray pump acceleration time (Ref. 8.2.14). The new lower AV (AVL) for LOCA conditions is calculated via the standard formula for a descending process as stated in Section 3.1. The new NTSP is calculated as the average of the upper and lower ALims rounded to the nearest 0.1 second.

UNDERVOLTAGE RELAY SETPOINTS DC-0919 Vol I DCD 1 Rev. 0 Page 47 The table below details the analysis for the Division I Loss of Voltage UV relay voltage AVs. Per the DECO File Cl-4180 (Ref. 8.2.1) methodology the Technical Specification AVs are specified for a decreasing voltage setpoint, so the existing lower AV (AVL) is analyzed for acceptability using the standard formulas for a descending process as stated in Section 3.1. The existing A VL is used to determine a maximum lower analytical limit. This computed lower analytical limit is then used to compute a minimum relay actuation voltage using the standard formula from Section 3.1. The acceptability of the existing A VL and NTSP is then verified by subtracting all the possible sources of error from the existing NTSP and verifying that the result is equal to or greater than the minimum relay actuation voltage based on the computed lower Alim. Although this is a descending process trip, because there is no particular requirement for the upper ALim, the existing upper A V (A VU) is analyzed for acceptability by applying the same process described above for an ascending process trip. The minimum upper ALim is determined by adding the combination of the non-drift errors to the existing AVU. The existing NTSP and upper AV are acceptable if the upper ALim minus the combination of all errors including drift is shown to be greater than the existing NTSP. The basic calculation is done in the 4160V bus voltage values. The 4160V values are converted to the 120V relay values by multiplying by the ratios from Section 3.3, which are 120/4200 for the P-P relay and

UNDERVOLTAGE RELAY SETPOINTS DC-0919 Vol I DCD 1 Rev. 0 Page 50 The table below determines new A V s and NTSPs for the degraded voltage UV relay voltages based on the new ALims provided by reference 8.2.14. Because the Technical Specification AVs are for a decreasing voltage setpoint, the lower AV (AVL) is determined via the standard formula for a descending process as stated in Section 3.1. The upper A V (A VU) is then determined by adding the maximum channel error to the operate NTSP. This will set the AVU at the maximum point at which the decreasing voltage can actuate the relay once all the possible sources of error have been considered.

The maximum Reset point is determined by dividing the AVU (max possible actuation point) by 0.995 based on the desired 0.5% differential between operate and reset voltages.

This maximum possible reset point must be :S the Upper Analytical Limit, which is the upper voltage determined in the voltage analysis, (Reference 8.2.14).

Good practice is to set the ALT equal to the VA when possible, or to use at least one half of the VA. Since the VA is +/-0.731 seconds, the existing +/-0.05 seconds is an order of magnitude too small. Thus it is increased in this analysis to a more realistically achievable

+/-0.5 seconds, and by output of this calculation will be changed in the calibration procedure.

UNDERVOLTAGE RELAY SETPOINTS DC-0919 Vol I DCD 1 Rev. 0 Page 52 The upper Alim for the LOCA time delay supports the 13 second EDG start time from the LOCA analysis (Ref. 8.2.19, UFSAR Tables 6.3-7 & 8.3-5). The EDG start circuit includes a separate time delay relay, and an additional 0.18 seconds is required to account for the closure times of the EDG output and RHR pump motor breakers.

Thus the upper ALim for the DV LOCA time delay is determined by subtracting the maximum EDG start timer delay and 0.18 seconds from the 13 second EDG start time for LOCA. Appendix G contains the determination of error associated with the EDG start timer relay. The Technical Specification A V s for the LOCA condition degraded voltage relays are for an increasing time setpoint, so a new upper A V (A VU) is calculated via the standard formula for an ascending process as stated in Section 3.1. The lower ALim is conservatively chosen as 5.50 seconds to be greater than the Core Spray pump acceleration time (Ref. 8.2.14). The new lower AV (AVL) for LOCA conditions is calculated via the standard formula for a descending process as stated in Section 3.1. The new NTSP is calculated as the average of the upper and lower ALims rounded to the nearest 0.1 second.

A setting of 15.20 seconds is chosen for this purpose. It is an acceptable, conservative value because it is equal to the NTSP plus the AL T. The existing calibration procedures (Ref. 8.2.7 through 8.2.10) include an ALT of +/- 1.0 sec. Per Cl-4180 (Ref. 8.2.1) the ALT is normally set equal to VA, unless noted otherwise.

The existing ALT of 1 sec is larger than the VA, and results in too large of a total error to stay within the Tech Spec A V s. Thus the AL T will be reduced to slightly more than one half of the VA, or 0.400 seconds. By output of this calculation, the calibration procedures will be revised to set AL T equal to 0.400 sec.

The Technical Specification non-LOCA time AVs must be shown to bound the combination of the individual time AVs for the undervoltage relay LOCA time plus the non-LOCA timer relay (Agastat) time.

I & II Secondary Undervoltage Scheme for Swing Bus 9.5.1 480 Volt Buses -Reactor Building

• Bus nc Position 3C Feed to Swing Bus MCC nCF (Normal)

• Bus nF Position 5C Feed to Swing Bus MCC nCF (Alternate)

DC-0919 Vol I DCD 1 Rev. 0 Page 56 This section determines the voltage setting for the undervoltage relays and the time setting for the time delay relay in both Divisions I and II. The additional undervoltage and time delay relays are an enhancement to the existing system. This scheme is for detecting a degraded voltage condition on the 480V swing bus after closure of the EDG output breakers.

This scheme detects when the voltage at the swing bus is less than the required voltage level for the motor-operated valves (MOV) connected to the swing bus and initiates a transfer of the swing bus feed to the other Division.

9.5.2 480 Volt Buses -Reactor Building Swing Bus Acceptance Criteria and Analysis The system conditions for this analysis are as follows:

• Loss of off-site power (off-site breaker open).

• Loss of coolant accident coincident with loss of off-site power.

• Degraded (voltage regulator failure) or no voltage on the 480V buses feeding Swing Bus MCC nC-F occurs just after the time of closing the EDG output breaker. The relays are set to trip when the 480V bus voltage has degraded to the point when safety systems fed from Swing Bus MCC nC-F should not be operated as continued operation may cause damage to safety system equipment.

There are two acceptance criteria by which to establish secondary (degraded)

UV setpoints:

1. The steady state voltage of the swing bus must not drop below the allowable limit required to operate the most limiting motor-operated valve. 2. The setpoint selected should be low enough to prevent unnecessary transfer of the swing bus. Undervoltage Relay Setting Criterion 1: (The voltage limit that the swing bus must not drop below to allow operation of the most limiting motor-operated valve at a degraded steady state voltage.)

The minimum voltage required at MCC nC-F is 93.07% of 480V per Section 10.2.3 of Ref. 8.2.14. The voltage drop from Bus nc to MCC nC-F is 3V per Ref. 8.2.36. The voltage drop from Bus nF to MCC F is 4V per Ref. 8.2.36. This results in required voltages at Bus nc and Bus nF, of93.7% and 93.91%, respectively.

Operation of the valves fed from this MCC is acceptable with voltages maintained above these values. The undervoltage relays on each bus were set to ensure bus voltage will not drop below 94.00%. The setpoints for these relays are calculated in Appendix B and are summarized below. Parameter Div 1 Div2 Max Reset 96.57% 96.57%

Max Dropout 96.09% 96.09%

Setpoint 95.04% 95.04%

Lower Operating Limit 94.00% 94.00%

Min Req'd Volts 93.70% 93.91 % Criterion 2: (The setpoint should be low enough to prevent unnecessary transfer of the swing bus.) The setpoint calculation for this relay in Appendix B calculates a reset value of 96.57%. EDG output voltage is very precise and maintains voltage regulation within +/-Yz% of 4160V (Ref. 8.2.37). Applying this tolerance to the voltage regulator setting results in a minimum expected voltage at the EDG terminals of 41 OOV (Ref.

UNDERVOLTAGE RELAY SETPOINTS DC-0919 Vol I DCD 1 Rev. 0 Page 57 8.2.36). This voltage results in a voltage of 476V (99.17%) at Bus 72C (Ref. 8.2.36). Bus 72F is fed via a voltage regulator that controls the voltage to 480V +/-l % (Ref. 8.2.14). Therefore, the voltage will be maintained above the maximum reset value of the relays preventing an unnecessary transfer of the swing bus. A single failure of the voltage regulator resulting in Bus 72C or Bus 72F voltages below the relay set points (including tolerances) will result in a transfer of the swing bus to the opposite division.

Based on the above evaluation, power to MCC 72C-F will be maintained to operate the motor operated valves fed from swing bus MCC 72C-F without an unnecessary transfer to the opposite division.

Time Delay (TD) Setting The time delay for the secondary undervoltage scheme must meet several acceptance criteria.

1. It should allow for the worse case motor starts (RHR and core spray). 2. It must not delay the ECCS injection timing. 3. It should be as short as possible to reduce equipment damage due to undervoltage.

Criterion 1: (TD should allow for the worse case motor starting transients at nominal voltages (RHR and core spray sequential starts)).

Large motor starts will drop the EDG voltage below the set point. The time delay must be long enough to prevent tripping for this transient.

Based on preoperational testing, PRET R3000.003 (Ref. 8.2.23) performed on Division I EDGs on August 14, 1984, and Division II EDGs on August 18, 1984, it was concluded that the recovery time for the EDG voltage is as follows: EDG 11 EDG 12 EDG 13 EDG 14 RHR Pump Start CS Pump Start 0.6 sec 0.3 sec 0.5 sec 0.2 sec 0.8 sec 0.3 sec 1.0 sec 0.3 sec See Attachment D for EDGs test characteristics.

For Criteria 1 the time delay has to be longer than one (1) second. Criterion 2: (TD must not delay the ECCS injection timing.) The time delay for the new relays must not delay the power availability for the ECCS injection.

In the present design, there is a 5 second gap for the load sequencer (1-2714-35, Ref. 8.2.33 and 1-2714-36, Ref. 8.2.34) of EDG 12 (Division I) to pick up the swing bus load in case there is an EDG 14 failure. This 5 second period can be used to set the time delay for UV relays to detect any true degraded voltage condition.

Therefore, the total delay can be as high as 5 seconds. The total time for ECCS injection is addressed in Safety Evaluation 89-0186 (Ref. 8.2.24). Criterion 3: (TD should be as short as possible to reduce equipment damage due to undervoltage.)

The time delay shall be as short as possible to avoid damaging any QA-l equipment since the QA-l motors can withstand the locked motor current for 15 seconds, as per DC-6348, Vol. I (Ref. 8.2.38) and the motors under degraded voltage will move slower than normal or get stalled and, in either case, the motor will have more current than its full load current. Therefore, 15 seconds can be used as upper boundary.

Time delay (TD) setting should be below 15 seconds. Conclusion

• From Criteria 1 above, the TD for the degraded UV scheme has to be larger than one (1) second.

• From Criteria 2 above, the time delay can be as high as 5 seconds,

• From Criteria 3 above, the time delay has to be less than 15 seconds. Undervoltage Relay Time Response The responding time for the undervoltage relay type (lTE-27) (Ref. 8.2.3) was calculated from the relay characteristic (Appendix B) and it varies between 0.2 to 1.3 seconds +/-10 %, tolerance per Procedure 35.318.008 (lTE Voltage Relay Testing) (Ref. 8.2.39). Therefore, the response times are as follows:

UNDERVOLTAGE RELAY SETPOINTS DC-0919 Vol I DCD 1 Rev. 0 Page 58

• Maximum response time for the undervoltage relay = 1.3+ 0.13 = 1.43 seconds.

• Minimum response time would be 0.2 -0.02 = 0.18 seconds. This was determined based on setting the time response for the UV relay at tap setting No.1. Total Time Delay for the Secondary Undervoltage Scheme The total time delay for the scheme should not exceed 5 seconds since the present design has a time delay of 5 seconds for the load sequencer ofEDG 12 as shown above. The total time delay for the scheme consists of:

• Maximum response time is the UV relay response plus time delay relay.

• Minimum response time allowable will be the time needed to override a large motor start on the EDG. The maximum responding time for the UV relay is 1.43 seconds. Therefore, the time delay relay time shall not exceed 5.0 -1.43 = 3.57 seconds. The minimum response time allowable will be the time needed to override a large motor start on the EDG. Per the PRET test results contained in EF2-72330 (Ref. 8.2.31), the longest RHR or core spray start is about 1 second. Time Delay Relay Setting In order to meet all criteria requirements above, the total responding time for the time delay relay shall be more than 1 second and lower than 3.57 seconds.

UNDERVOLTAGE RELAY SETPOINTS APPENDIX A EF-2-FSAR ITEM 222.31A DC-0919 Vol I DCD 1 Rev. 0 Page 59 Page 1 of2 Your response to Item 222.31 states that manual operator action is required to isolate the emergency buses from a degraded voltage condition.

We find this to be unacceptable and require the installation of an automatically initiated protection scheme which shall satisfy the following criteria.

a. Class IE equipment shall be utilized and shall be physically located at and electrically connected to the emergency switchgear.

b. An independent scheme shall be provided for each Division of emergency power. c. The selection of voltage and time delay set points shall be determined from an analysis of the voltage requirements of the safety-related loads at all onsite system distribution levels. d. The time delay selected shall be based on the following conditions:

1. The allowable time delay, including margin, shall not exceed the maximum time delay associated with the availability of power that is assumed in the accident analysis;

2. The time delay shall minimize the effect of short duration disturbances from reducing the availability of the offsite power source(s);

and 3. The allowable time duration of a degraded voltage condition at all distribution system voltage levels shall not result in failure of safety systems or components.

e. The voltage monitors shall automatically initiate the disconnection of offsite power sources by tripping the emergency bus feeder breaker whenever the voltage set point and time delay limits have been exceeded and the associated diesel generator shall be signaled to start and accept load. f. The set points for this scheme shall be design dependent but should approximate the following envelopes:

1. Voltage set point between 87 and 90 % of nominal. 2. Time delay setting of between 6 and 10 seconds. GED1259/4.21 030985

At least Four (4) cases will be built and used during the study. If further cases are required to verify system stability then the study model will be expanded to address all issues. Based on the known system requirements the four cases will be sufficient.

The Fermi 120kV peaking generation was modeled offline in all four cases, to stress the area conditions.

The four cases are as follows:

• The first case, will be summer peak case with the expected full generation dispatch was modeled and is designated Case lOON (normal).

• The second case will be summer peak load, but with several nearby generators modeled out of service (Monroe 2, Trenton Channel 9 & Whiting 3 off). This case was built to stress the voltage conditions in the Fermi area and is designated Case 100S (stressed).

• The third case will be based on the original peak case, lOON, Case 100EF represents E. Fermi 2 unit offline.

• The fourth case will be an 80% (conforming load scaled down only) ITCTlMichigan Electric Transmission Company (METC) load case, with an economic order generation reduction.

This will be the system condition ITCT uses to test transient stability, since reduced load and reduced generation is the most severe for transient stability.

Page 13 INTRODUCTION These instructions contain the information required to properly install, operate, and test certain ABB Circuit-ShieldŽ single-phase undervoltage and overvoltage relays, Types 27, 270, 27H, 590, and 59H. See the section on Testing for single-phase voltage relays covered by earlier issues of this instruction book. The relay is housed in a case suitable for conventional semiflush panel mounting.

All connections to the relay are made at the rear of the case and are clearly numbered.

Relays of the 411B, 411R, and 411C catalog series are similar to relays of the 211B, 211R, and 211C series. Both series provide the same basic functions and are of totally drawout construction; however, the 411B, 411R, and 411C series relays provide integral test facilities.

Also, sequenced disconnects on the 411 series vent nuisance operation during withdrawal or insertion of the relay if the normally-open contacts are used in the application.

Most settings plastic cover. relay cover. are made on the front panel of the relay, behind a removable clear The target is reset by means of a pushbutton extending through the PRECAUTIONS The following precautions should be taken when applying these relays: 1. Incorrect wiring may result in damage. Be sure wiring agrees with the connection diagram for the particular relay before energizing.

Important:

connections for the 411 catalog series units are different from the 211 series units. 2. Apply only the rated control voltage marked on the relay front panel. The proper polarity must be observed when the dc control power connections are made. 3. For relays with dual-rated control voltage, withdraw the relay from the case and check that the movable link on the printed circuit board is in the correct position for the system control voltage. 4. High voltage insulation tests are not recommended.

for additional information.

See the section on testing 5. The entire circuit assembly of the relay is removable.

The unit should insert smoothly.

Do not use excessive force. 6. Follow test instructions to verify that the relay is in proper working order. CAUTION: since troubleshooting entails working with energized equipment, care should be taken to avoid personal shock. Only competant technicians familiar with good safety practices should service these devices. PLACING THE RELAY INTO SERVICE 1. RECEIVING, HANDLING, STORAGE Upon receipt of the relay (when not included as part of a switchboard) examine for shipping damage. If damage or loss is evident, file a claim at once and promptly notify Asea Brown Boveri. Use normal care in handling to avoid mechanical damage. Keep clean and dry.

connections units compared to 2118, 211R, and 211C proper polarity.

7. Typical external connections are shown in are diFferent for 4118, 411R, and 411C series units. Control power must be connected in the For relays with dual-rated control power: before energizing, withdraw the relay from its case and inspect that the movable link on the lower printed circuit board is in the correct position for the system control voltage. (For units rated 110vdc, the link should be placed in the position marked 125vdc.) Relays rated for use with 120vac control power have an internal isolation transformer connected to relay terminals 7 and 8. Polarity of the ac control power to these terminals need not be observed.

These relays have metal front panels which are connected through printed circuit board runs and connector wiring to a terminal at the rear of the relay case. The terminal is marked "G". In all applications this terminal should be wired to ground. 3. SETTINGS PICKUP (VOLTS) The pickup taps are labelled by the actual value of 'ac input voltage which will cause the relay to operate. Note: operating voltage values other than the specific values provided by the taps can be obtained by means of an internal adjustment potentiometer.

See section on testing for setting procedure.

On these relay models there is no adjustment for the differential between the operate and reset voltage values. TIME DIAL The time dial taps are identified as 1,2,3,4,5,6.

Refer to the time-voltage teristic curves in the Application section. Time dial selection is not provided on relays with an Instantaneous operating characteristic.

4. INDICATORS Target: An operation target is provided.

The target is set electronically when the output contacts transfer.

The target will retain its indication on loss of dc control power. In order to reset the target, normal dc control power must be present and a "normal" ac voltage condition must exist; in other words, for an undervoltage relay the voltage must be higher than the set point, and for overvoltage relays, lower. APPLICATION DATA The ABB Circuit-ShieldŽ single-phase voltage relays covered by this instruction book provide a wide range of application including undervoltage protection for motors, over and undervoltage protection for generators, and automatic bus transfer.

The relays provide good accuracy and repeatability, and have a flat response over a frequency range of 15 to 400 hertz. Undervoltage Relay, Type 27, catalog series 211B, 211R, 411B, and 411R: Typical applications include general purpose undervoltage protection for incoming lines, and initiation of transfer in automatic bus transfer schemes. Typical external connections are shown in Figures 2. The relay has an inverse time curve as shown in TVC-605817.

OC-0919 Vol lOCO 1 Rev. 0 Attachment B Page 3 of 15 19 18.4.7-2 Page 4 Single-Phase Voltage Relays Undervoltage 27D, catalog series 2119, 211R, 4119 and 411R: Typical applications include the initiation of transfer in automatic bus transfer schemes. Typical external connections are shown in Figure 3. The Type 27D relay has a definite-time characteristic with 2 ranges available:

0.1-1 second and 1-10 seconds, as shown in TYC-605820 and TYC-605821.

Undervoltage Relays, Type 27H, catalog series 2119, 211R, 4119, 411R: Typical applications include instantaneous undervoltage detection for bus transfer schemes, and for generator intertie schemes. The low range relay is used as a residual voltage detector in motor bus transfer schemes. Typical connections are shwon in Figure 3. The relay has an instantaneous operating time as shown in TYC-605819.

Overvoltage Relays, Type 59H and Type 59D, catalog series 211C and 411C: These instantaneous and definite time overvoltage relays are companions to the Type 27H and Type 27D undervoltage relays, and offer' similar characteristics where overvoltage protection is required.

The time voltage characteristic for the Type 59D is given in TYC-605839.

For the Type 59H the maximum operating time above 1.05 times pickup is 16 milliseconds.

Notes on the Use of AC Control Power In general the use of a station battery to provide a reliable source of tripping and control power is preferred.

However, many of the relay types described in this 19 are available for use with 120 vac control power. The output contacts may be used in a 120 vac circuit or in a capacitor trip circuit where the capacitor voltage is no more than 170 vdc nominal. (Consult factory if the higher rating is required:

"-CAP" catalog suffix.) The control power for these relays should never be taken from a capacitor trip circuit as the voltage is too high and the relay will drain the capacitor in the event of loss of AC supply. Type 27 and Type 27D Undervoltage Relays used with 120 vac control power in the "self-powered" mode, with both signal and control power taken from the same source, will not maintain their timing characteristics if the voltage drops below approximately 65 volts. The relay will trip immediately.

If this characteristic is undesirable for a particular application, the Type 27H instantaneous relay should be used followed by a pneumatic timer with time delay on dropout. A contact from the timer would be used to trip. The timer would be picked up by a contact of the Type 27H under "normal" line conditions.

With undervoltage or loss of voltage, the timer would time out and close its contact in the tripping circuit. If the voltage loss were momentary, the timer would allow riding through the loss without tripping.

This arrangement thus makes the time delay independent of control power and retains the benefits of accurate voltage sensing provided by the Type 27H relay.

MAINTENANCE AND RENEWAL PARTS No routine maintenance is required on these relays. Follow test instructions to verify that the relay is in proper working order. We recommend that an inoperative relay be returned to the factory for repair; however, a schematic diagram, and in some cases a circuit description, can be provided on request. Renewal parts will be quoted by the factory on request. There are many earlier versions of these single-phase voltage relays which are now obsolete and have been superseded.

If you have a relay which has its front panel stamped with Instruction Book IB 18.4.7-2, but which is not covered by this Issue E of the book, you should request Issue D from the factory. Also see paragraph 6 on obsolete relays. 211 Series Units Drawout circuit boards of the same catalog number are interchangib1e.

A unit is identified by the catalog number stamped on the front panel and a serial number stamped on the bottom side of the drawout circuit board. The board is removed by using the metal pull knobs on the front panel. Removing the board with the unit in service may cause an undesired operation.

An 18 point extender board (cat 200X0018) is available for use in troubleshooting and calibration of the relay. 411 Series Units Metal handles provide leverage to withdraw the relay assembly from the case. Removing the unit in an application that uses a normally closed contact will cause an operation.

The assembly is identified by the catalog number stamped on the front panel and a serial number stamped on the bottom of the circuit board. Test connections are readily made to the drawout relay unit by using standard banana plug leads at the rear vertical circuit board. This rear board is marked for easier identification of the connection points. A test plug assembly, catalog units. This device plugs into the all external circuits wired to details on the use of this device. 2. HIGH POTENTIAL TESTS 400X0002 is available for use with the 411 series relay case on the switchboard and allows access to the case. See Instruction Book IB 7.7.1.7-8 for High potential tests are not recommended.

A hi-pot test was performed at the factory before shipping.

If a control wiring insulation test is required, partially withdraw the relay unit from its case sufficient to break the rear connections before applying the test voltage. 3. BUILT-IN TEST FUNCTION Be sure to take all necessary precautions if tests are run with the main circuit energized.

The built-in test is provided as a convenient functional test of the relay and iated circuit. When you depress the button labelled TRIP, the measuring and timing circuits of the relay are actuated.

When the relay times out, the output contacts transfer to trip the circuit breaker or other associated circuitry, and the target is displayed.

The test button must be held down continuously until operation is obtained.

For the undervoltage relays, the timing is equivi1ent to that for a complete loss of voltage. DC-0919 Vol I DCD 1 Rev. 0 Attachment B Page 12 of 15 Single-Phase Voltage Relays 4. ACCEPTANCE TESTS IB 18.4.7-2 Page 13 Follow calibration procedures under paragraph

5. On inverse or definite-time relays, select Time Dial For undervoltage relays check timing by dropping voltage from 120 to 0 volts. For overvoltage relays check timing by increasing voltage to 150% of pickup. Tolerances should be within +/-5% for pickup and +/-10% for timing. Calibration may be adjusted to the final settings required by the application at this time. 5. CALIBRATION A typical test circuit is shown in Figure 3. Connect the relay to a proper source of control voltage to match its nameplate rating and internal plug setting for rated units. The ac test source should be harmonic-free.

Sources using nant-transformer regulators should not be used due to high harmonic content. For relays with time delay, the time-dial tap pin should be placed in position (fastest) when checking pickup and dropout voltages.

The voltage should be varied slowly to remove the effect of the time delay from the voltage measurements.

Pickup may be varied between the fixed tap values by adjusting the internal pickup calibration potentiometer.

For 211 series units the 18 point extender board provides easier access to the internal pots. Place the voltage tap pin in the nearest value and adjust the internal pot, repeating the test until the desired operating voltage is obtained.

If the internal pot has insufficient range, move the tap pin to the next closest value and try again. Similarly the time delay may be adjusted higher or lower than the values shown on the time-voltage curves by means of the internal pot. The internal calibration pots are identified as follows: Relay Type Type 27, Type 59 Types -27D, -27H Types -59D, -59H 6. OBSOLETE UNITS Pickup Time Delay R10 R25

• R13 R38

• Note: RT can also be used as a secondary means of adjustment.

The chart on page 8 indicates that certain of the 211 and 411 series single-phase voltage relays have been replaced by improved versions.

The following gives a quick reference to the instruction books for the newer units. Should you need the tion book for the earlier units that are nameplated to call for IB 18.4.7-2, request issue D from the factory. Type 59, Inverse-time Overvoltage Relay: Catalog series 211C11xx replaced by 210C11x5 and 410C11x5 series, see IB 7.4.1.7-1.

Type 59G, Ground Overvoltage Relay: Catalog series 211E replaced by 210E and 410E series, see IB 7.4.1.7-9.

Type 27G, Third Harmonic Undervoltage Relay: Catalog series 211Q replaced by 410Q series, see IB 7.4.1.7-9.

Type 27/59, Under/Overvoltage Relay: Catalog series 211D replaced by 410D series, see IB 7.4.1.7-1.

Types 27/59A, -27/59D, -27/59H Under/Overvoltage Relay: Catalog series 211L replaced by Type 27N, catalog series 211T and 411T, see IB 7.4.1.7-7. (Note: the 211L relays were not used for overvoltage protection; they were undervoltage relays with adjustable pickup and dropout voltages.)

IB 18.4.7-2 Page 15 The note with Figure 2 indicates that the terminal numbers associated with the output contact labelled "X" and "Y" in the diagram must be selected by referring to the internal connection diagram and contact logic chart for the particular relay being considered.

As a cross-reference in this selection, the following table lists the terminals associated with the normally-open contacts that close for tripping for the basic relay function.

In other words, for an undervoltage relay, the contacts that close for undervoltage, and for an overvoltage relay the contacts that close on voltage. An "x" in the catalog number represents any digit ("don't care"). Undervoltage Relays Contacts that CLOSE on Undervoltage

Page 10 INTRODUCTION Attachment 0 Page 2 of 12 These instructions contain the information required to properly install, operate, and test certain single-phase undervoltage relays type 27N, catalog series 211T and 411T; and overvo1tage relays, type 59N, catalog series 211U and 411U. The relay is housed in a case suitable for conventional semi flush panel mounting.

All connections to the relay are made at the rear of the case and are clearly numbered.

Relays of the 411T, and 411U catalog series are similar to relays of the 211T, and 211U series. Both series provide the same basic functions and are of totally drawout construction; however, the 411T and 411U series relays provide integral test facilities.

Also, sequenced disconnects on the 410 series prevent nuisance operation during withdrawal or insertion of the relay if the normally-open contacts are used in the application.

Basic settings are made on the front panel of the relay, behind a removable clear plastic cover. Additional adjustment is provided by means of calibration meters inside the relay on the circuit board. The target is reset by means of a pushbutton extending through the relay cover. PRECAUTIONS The following precautions should be taken when applying these relays: 1. Incorrect wiring may result in damage. Be sure wiring agrees with the connection diagram for the particular relay before energizing.

2. Apply only the rated control voltage marked on the relay front panel. The proper polarity must be observed when the dc control power connections are made. 3. For relays with dual-rated control voltage, withdraw the relay from the case and check that the movable link on the printed circuit board is in the correct position for the system control voltage. 4. High voltage insulation tests are not recommended.

Do not use excessive force. The unit should insert 6. Follow test instructions to verify that the relay is in proper working order. CAUTION: since troubTeshooting entails working with energized equipment, care shouTd be taken to avoid persona 7 shock. On1y campetant technicians ramiliar with good ssrety practices shouTd service these devices. . PLACING THE RELAY INTO SERVICE 1. RECEIVING, HANDLING, STORAGE Upon receipt of the relay (when not included as part of a switchboard) examine for shipping damage. If damage or loss is evident, file a claim at once and promptly notify Asea Brown Boveri. Use normal care in handling to avoid mechanical damage. Keep clean and dry.

in Figure 2. Internal connections and Control power must be connected in the proper For relays with dual-rated control power: before energlzlng, withdraw the relay from its case and inspect that the movable link on the lower printed circuit board is in the correct position for the system control voltage. (For units rated 110vdc, the link should be placed in the position marked 125vdc.) These relays have an external resistor wired to terminals 1 and 9 which must be in place for normal operation.

The resistor is supplied mounted on the relay. These relays have metal front panels which are connected through printed circuit board runs and connector wiring to a terminal at the rear of the relay case. The terminal is marked "G". In all applications this terminal should be wired to ground. 3. SETTINGS PICKUP The pickup voltage taps identify the voltage level which the relay will cause the output contacts to transfer.

DROPOUT The dropout voltage are provided for pickup. taps are identified as a percentage of the pickup voltage. Taps and of pickup, or, and of Note: operating voltage values other than the specific values provided by the taps can be obtained by means of an internal adjustment potentiometer.

See section on testing for setting procedure.

TIME DIAL The time dial taps are identified as 1,2,3,4,5,6.

Refer to the time-voltage teristic curves in the Application section. Time dial selection is not provided on relays with an Instantaneous operating characteristic.

The time delay may also be varied from that provided by the fixed tap by using the internal calibration ment. 4. OPERATION INDICATORS The types 27N and 59N provide a target indicator that is electronically actuated at the time the output contacts transfer to the trip condition.

The target must be manually reset. The target can be reset only if control power is available, AND if the input voltage to the relay returns to the "normal" condition.

An led indicator is provided for convenience in testing and calibrating the relay and to give operating personnel information on the status of the relay. See Figure 4 for the operation of this indicator.

Units with a U_L" suffix on the catalog number provide a gr-een led to indicate the presence of control power and internal power supply voltage.

Attachment 0 Page 4 of 12 m7.4.1.7-7 Page 4 Vol IDeO 1 Rev. 0 Voltage APPLICATION Single-phase undervoltage relays and overvoltage relays are used to provide a wide range of protective functions, including the protection of motors and generators, and to initiate bus transfer.

The type 27N undervoltage relay and type 59N overvoltage relay are designed for those applications where exceptional accuracy, repeatability, and long-term stability are required.

Tolerances and repeatability are given in the Ratings section. Remember that the accuracy of the pickup and dropout settings with respect to the printed dial markings is generally not a factor, as these relays are usualli calibrated in the field to tain the particular operating values for the application.

At the time of fie1d ibration, the accuracy of the instruments used to set the relays is the important factor. Multiturn internal calibration potentiometers provide means for accurate adjustment of the relay operating points, and allow the difference between pickup and dropout to be set as low as 0.5%. The relays are supplied with instantaneous operating time, or with definite-time delay characteristic.

The definite-time units are offered in four time delay ranges: 0.1-1 second, 1-10 seconds, 2-20 seconds or 10-100 seconds. An accurate peak detector is used in the types 27N and 59N. Harmonic distortion in the AC waveform can have a noticible effect on the relay operating point and on measuring instruments used to set th. relay. An internal harmonic filter is available as an option for those applications where waveform distortion is a factor. The harmonic filter attenuates all harmonics of the 50/60 Hz. input. The relay then basically operates on the fundamental component of the input voltage signal. See figure 5 for the typical filter response curve. To specify the harmonic filter add the suffix "-HF" to the catalog number. Note in the section on ratings that the addition of the harmonic filter does reduce somewhat the repeatability of the relay vs. temperature variation.

In applications where waveform distortion is a factor, it may be desirable to operate on the peak voltage. In these cases, the harmonic filter would not be used.

Follow test instructions to verify that the relay is in proper working order. We recommend that an inoperative relay be returned to the factory for repair; however, a circuit description booklet CD7.4.1 .7-7 which includes schematic diagrams, can be provided on request. Renewal parts will be quoted by the factory on request. 211 Series Units Drawout circuit boards of the same catalog number are interchangible.

A unit is identified by the catalog number stamped on the front panel and a serial number stamped on the bottom side of the drawout circuit board. The board is removed by using the metal pull knobs on the front panel. Removing the board with the unit in service may cause an undesired operation.

An 18 point extender board (cat 200X0018) is available for use in troubleshooting and calibration of the relay. 411 Series Units Metal handles provide leverage to withdraw the relay assembly from the case. Removing the unit in an application that uses a normally closed contact will cause an operation.

The assembly is identified by the catalog number stamped on the front panel and a serial number stamped on the bottom of the circuit board. Test connections are readily made to the drawout relay unit by using standard banana plug leads at the rear vertical circuit board. This rear board is marked for easier identification of the connection points. Important:

these relays have an external resistor mounted on rear terminals 1 and 9. In order to test the drawout unit an equivi1ent resistor must be connected to terminals 1 & 9 on the rear vertical circuit board of the drawout unit. The resistance value must be the same as the resistor used on the relay. A 25 or 50 watt resistor will be sufficient for testing. If no resistor is available, the resistor assembly mounted on the relay case could be removed and used. If the resistor from the case is used. be sure to remount it on the case at the conc1usion of testing. Test Plug: A test plug assembly, catalog number 400X0002 is available for use with the 410 series units. This device plugs into the relay case on the switchboard and allows access to all external circuits wired to the case. See Instruction Book IB 7.7.1.7-8 for details on the use of this device. 2. HIGH POTENTIAL TESTS High potential tests are not recommended.

A hi-pot test was performed at the factory before shipping.

If a control wiring insulation test is required, partially withdraw the relay unit from its case sufficient to break the rear connections before applying the test voltage. 3. BUILT-IN TEST FUNCTION Be sure to take all necessary precautions if the tests are run with the main circuit energized.

The built-in test is provided as a convenient functional test of the relay and iated circuit. When you depress the button labelled TRIP, the measuring and timing circuits of the relay are actuated.

When the relay times out, the output contacts transfer to trip the circuit breaker or other associated circuitry, and the target is displayed.

The test button must be held down continuously until operation is obtained.

4. ACCEPTANCE TESTS DC-0919 Vol lOCO 1 Rev. 0 Single-Phase Voltage Relays Attachment 0 Page 11 of 12 IB 7.4.1.7-7 Page 11 Follow the test procedures under paragraph

5. For definite-time units, select Time Dial #3. For the type 27N, check timing by dropping the voltage to of the dropout voltage set (or to zero volts if preferred for simplification of the test). For the type 59N check timing by switching the voltage to of pickup (do not exceed max. input voltage rating.) Tolerances should be within those shown on page 5. If the settings required for the particular application are known, use the procedures in paragraph 5 to make the final adjustments.

5. CALIBRATION TESTS Test Connections and Test Sources: Typical test circuit connections are shown in Figure 8. Connect the relay to a proper source of dc control voltage to match its nameplate rating (and internal plug setting for dual-rated units). Generally the types 27N and 59N are used in tions where high accuracy is required.

The ac test source must be stable and free of harmonics.

A test source with less than harmonic distortion, such as a corrector" is recommended.

Do not use a voltage source that employs a ferroresonant transformer as the stabilizing and regulating device, as these usually have high harmonic content in their output. The accuracy of the voltage measuring instruments used must also be considered when calibrating these relays. If the resolution of the ac test source adjustment arrangement using two variable transformers shown in "fine" adjustments is recommended.

level and the direction of voltage Figure 4. on the front panel for convenience in determining The action of the indicator depends on the voltage change, and is best explained by referring to The calibration potentiometers mentioned in the following procedures are of the multi-turn type for excellent resolution and ease of setting. For catalog series 211 units, the 18 point extender board provides easier access to the calibration pots. If desired, the calibration potentiometers can be resealed with a drop of nail polish at the completion of the calibration procedure.

Setting Pickup and Dropout Voltages:

Pickup may be varied between the fixed taps by adjusting the pickup calibration potentiometer R27. Pickup should be set first, with the dropout tap set at 99% (60% on "low dropout units"). Set the pickup tap to the nearest value to the desired setting. The calibration potentiometer has approximately a +/-5% range. Decrease the voltage until dropout occurs, then check pickup by increasing the voltage. adjust and repeat until pickup occurs at precisely the desired voltage. Potentiometer R16 is provided to adjust dropout. Set the dropout tap to the next lower tap to the desired value. Increase the input voltage to above pickup, and then lower the voltage until dropout occurs. Readjust R16 and repeat until the required setting has been made. Setting Time Delay: Similarly, the time delay may be adjusted higher or lower than the values shown on the time-voltage curves by means of the time delay calibration potentiometer R41. On the type 27N, time delay is initiated when the voltage drops from above the pickup value to below the dropout value. On the type 59N, timing is initiated when the voltage increases from below dropout to above the pickup value. Referring to Fig. 4, the relay is "timing out" when the led indicator is lighted. External Resistor Val yes: The following resistor values may be used when testing 411 series units. Connect to rear connection points 1 & 9.

RE: Repeatability of Agastat E7012 Series Relays Hello, My point is that i didn't say it he did, regarding the 2/3 multiplier.

I understand the idea, i didn't say it , that's all. Regarding the second question, does 5% represent near 100%? In the testing we do at the factory, we can't ship a unit unless we verify that its repeat accuracy is within +/-5%, so by that measure, every relay we ship must have a repeat accuracy of +/-5%. (or we would n't ship it, right?) thanks!! for asking. Dick Sinclair Sr. Product Engineer Global Aerospace, Defense & Marine Tyco Electronics Corporation 1396 Charlotte Hwy.

RE: Repeatability of Agastat E7012 Series Relays Dick Sinclair, Thank you for the answer! What he was trying to say with the 2/3 multiplier is to define how much confidence is associated with the data that support the 5% repeatability.

Statistically, if you have a large enough population of test data, then it can be said to represent 99.5% or -100% of the population, so we can take the stated accuracy in our calcs as a value representing 3 standard deviations.

Most accuracy/setpoint calculations determine the error to a 2 standard deviation value, so what he was trying to say was that the stated accuracy of 5% was based on sufficient data to represent a 3 sigma value, so by multiply by 2/3 he would get a 2 standard deviation value. So the question is, for the 7012 relay with a stated repeatability of 5%, does this represent near 100% of the population?

RE: Repeatability of Agastat E7012 Series Relays Hello, Thank you for contacting us regarding the repeat accuracy of E7000 and 7000 series relays. Page 2 of5 I have only one contention with the information you provided and that is the "2/3 multiplier".

I am not sure what that means or if I said that. Since i don't know what it means it would be difficult for me to understand how to quote it to Mr. Hoolahan (sic). Anyway, other than that, the information is correct regarding the comparison of the Agastat 7000s and E7000s. Thanks!!

Forward to R. Sinclair Customer (Patricia Ugorcak) 06/16/201001:05 PM 06/16/2010 11 :26 AM I have a copy of a telephone conversation (file attached) from 2003 with Dick Sinclair pertaining to the E7012 accuracy speicifications.

It makes the following points:

• The relay specifications as published are current and valid.

• The specifications are considered bounding values. Use of2/3 multiplier would be appropriate for 95% confidence interval calculation.

• Series 7000 and Series E7000 are made from identical piece parts.

• The only difference in the manufacturing process between the models is the QA and testing associated with the nuclear qualified E7000 series not the same as 7000 series.

• Repeatability specification for E7000 series (+/-10%) is greater than 7000 series

(+/-5%) due to cumulative effects of harsh testing performed on E7000 series relays.

• If a E7000 series and 7000 series relay were operated in the same mild environment, the improved performance characteristics associated with the 7000 series relay would be expected for both relays.

• Due to similarity in design, temperature variation specifications associated with the 7000 series can be applied to the E7000 series. Is this still true?

I need to verifY the actula repeatability of the E7012 when not subject harsh environmental effects and seismic events. This is matter of urgency in support ofDTE Energy's Fermi Nuclear 2 Station. 7/7/2010

27 calibration, guarantee spec. doc Hi Patricia We do not have any specific data as to the repeatability for the Type 27D relay, however I am including a note from one of our Engineers that may address your issue. Although this note refers to the Type 27 it does mention the 27D as well. Please keep in mind that the 27D is a general purpose relay and that the 27N may be better suited for a more accurate application.

Hope this helps and let me know if you need any additional information;.

Thanks Don (See attachedfile:

27 calibration, guarantee spec. doc) ----Original message ----I am performing an accuracy calc for the Enrico Fermi 2 Nuclear Power Station for an ABB Type 27D relay, full model number 211R4175.

Instruction IB 18.4.7-2 states control power and temperature effects on repeatability, but no specific repeatability effect other than the 5% if using the dial setting. Do you have any information on the base repeatability for the 27D, a number that should be combined with the temperature and control power variation effects to get the total inaccuracy?

7/7/2010 DC-0919 Rev. F Vol. I DCD-1 Attachment Q Page 2 of 2 Refer to the Specifications (page 5), of the latest version of IB 18.4.7-2.

The pickup/dropout difference for the Type 27 is "less than 0.5 percent" (The 27D and 27H relays are about 3 percent).

It should be practical to calibrate the Type 27 to within 0.5 volt of the desired undervoltage operating voltage using the internal calibration pot R10 per the info on pages 13 and 14. Time Dial # 1 should be used when calibrating the operating voltage. A 15 minute warm-up time should be used with dc control and 120 volts nominal ac voltage applied before making the final calibration adjustment.

Repeatability of the operating point should be within 0.2 volt for short term testing at constant temperature and constant control voltage. Repeatability for variations in temperature and control voltage is given in the page 5 specifications.

No guarantees are available for long term stability.

The Type 27 is a general purpose undervoltage relay and will have reasonable stability

-but not the high performance of the Type 27N design. A 2% repeatability value over a 1 year calibration interval would be a conservative assumption (at same temperature and dc control voltage as the original calibration)

The Type 27N is available with Definite-time delay, but not with the Inverse curve of the Type 27.

Resolution is often expressed in percent, parts-per-million (ppm), counts, or bits. For example, a 6 1/2-digit multimeter with 20% overrange capability can display a measurement with up to 1,200,000 counts of resolution.

This corresponds to about 0.0001 % (1 ppm) of full scale, or 21 bits including the sign bit. All four specifications are equivalent.

Accuracy Accuracy is a measure of the "exactness" to which the multimeter's measurement uncertainty can be determined relative to the calibration reference used. Absolute accuracy includes the multimeter's relative accuracy specification plus the known error of the calibration reference relative to national standards (such as the U.S. National Institute of Standards and Technology).

To be meaningful, the accuracy specifications must be accompanied with the conditions under which they are valid. These conditions should include temperature, humidity, and time. There is no standard convention among multimeter manufacturers for the confidence limits at which specifications are set. The table below shows the probability of non-conformance for each specification with the given assumptions.

Specification Criteria Mean +/- 2 sigma Mean +/- 3 sigma Mean +/- 4 sigma Probability of Failure 4.5% 0.3% 0.006% Variations in performance from reading to reading, and instrument to instrument, decrease for increasing number of sigma for a given specification.

This means that you can achieve greater actual measurement precision for a specific accuracy specification number. The Agilent 34401A is designed and tested to meet performance better than mean +/-4 sigma of the published accuracy specifications.

• Available in 2-pole or 4-pole models.

• Numerous enclosure options: explosion proof, dust tight, watertight, hermetically-sealed, NEMA 1.

• Auxiliary timed and instantaneous switches can be added for greater switching flexibility.

• Many mounting options: Surface mount, Panel mount, Octal plug-in mounting.

• Options: quick-connect terminals, dial stops, and transient protection module.

• Easy-to-reach screw terminals, all on the face of the unit, clearly identified.

• Modular assembly -timing head, coil assembly and switchblock are all individual modules, with switches field-replaceable.

Design & Construction There are three main components of Series 7000 liming Relays: Calibrated Timing Head uses no needle valve, recirculates air under controlled pressure through a variable orifice to provide linearly adjustable timing. Patented design provides instant recycling, easy adjustment and long service life under severe operating conditions.

Precision-Wound Potted Coil module supplies the initial motive force with minimum current drain. Total sealing without external leads eliminates moisture problems, gives maximum insulation value. Snap-Action Switch Assembly -custom-designed over-center mechanism provides greater contact pressure up to transfer time for positive, no flutter action. Standard switches are DPDT arrangement, with flexible beryllium copper blades and silver-cadmium oxide contacts.

Special "timing-duty" design assures positive wiping action, sustained contact sure and greater heat dissipation during long delay periods. Each of these subassemblies forms a self-contained module which is then assembled at the factory with the other two to afford a wide choice of operating types, coil voltages, and timing ranges. The squared design with front terminals and rear mounting permits the grouping of Series 7000 units side-by-side in minimum panel space. Auxiliary switches may be added in the base of the unit, without affecting the overall width or depth. Operation Two basic operating types are available. "On-Delay" models provide a delay period on energization, at the end of which the switch transfers the load from one set of contacts to another. energizing the unit during the delay period immediately recycles the unit, readying it for another full delay period on re-energization.

In "Off-Delay" models the switch transfers the load immediately upon energization, and the delay period does not begin until the unit is energized.

At the end of the delay period the switch returns to its original sition. Re-energizing the unit during the delay period immediately resets the timing, readying it for another full delay period on de-energization.

No power is required during the timing period. In addition to these basic operating types, "Double-Head" models offer sequential delays on pull-in and drop-out in one unit. With the addition of auxiliary switches the basic models provide two-step timing, pulse actuation for interlock circuits, or added circuit capacity.

On-delay model 7012 (delay on pickup) Applying continuous voltage to the coil (L l-L2) starts a time delay lasting for the preset time. During this period the normally closed contacts (3-5 and 4-6) remain closed. At the end of the delay period the normally closed contacts break and the normally open contacts (1-5 and 2-6) make. The contacts main in this transferred position until the coil is deenergized, at which time the switch instantaneously returns to its original position.

De-energizing the coil, either during or after the delay period, will recycle the unit within 50 msec. It will then provide a full delay period upon re-energization, regardless of how often the coil voltage is ed before the unit has been permitted to "time-out" to its full delay setting. Off-delay model 7022 (delay on dropout) Applying voltage to the coil (for at least 50 msec) will instantaneously transfer the switch, breaking the mally closed contacts (1-5 and 2-6), and making the normally open contacts (3-5 and 4-6).

Contacts remain in this transferred position as long as the coil is energized.

The time delay begins immediately upon de-energization.

At the end of the lay period the switch returns to its normal position.

Re-energizing the coil during the delay period will immediately return the timing mechanism to a point where it will provide a full delay period upon subsequent energization.

The switch remains in the transferred position.

To increase the versatility of the basic timer models, auxiliary switches may be added to either on-delay or off-delay types. They switch additional circuits, provide two-step timing action, or furnish electrical interlock for sustained coil energization from a momentary impulse, depending on the type selected and its adjustment.

Because of their simple attachment and adjustment features, they can be installed at the factory or in the field, by any competent mechanic.

All auxiliary switches are SPDTwith UL listings of 10A@ 125,250, or 480 VAC. A maximum of one Code T or two Code L auxiliary switches may be added to each relay. The Lor LL switch is available with on-delay relays only. The T switch is available with both the on-delay and off-delay relays. Auxiliary Switch Options for On-Delay Instant Transfer (Auxiliary Switch Code L, maximum of 2 per relay.) 1. Energizing coil begins time delay and transfers auxiliary switch. 2. Main switch transfers after total preset delay. 3. De-energizing coil resets both switches instantly.

Auxiliary Switch Options for Off-Delay In these models the same auxiliary switch provides either two-step timing or instant transfer action, depending on the adjustment of the actuator.

Two-Step Timing (Auxiliary Switch Code T, maximum of 1 per relay.) 1. Energizing coil transfers main and auxiliary switches instantly.

2. De-energizing coil begins time delay. 3. After first delay auxiliary switch transfers.

2. De-energizing coil resets auxiliary switch and begins time delay. 3. Main switch transfers after total preset delay. Auxiliary switch is factory adjusted to give instant transfer operation, but may be easily adjusted in the field to provide two-step timing. The Double Head model provides delayed switch transfer on energization of its coil, followed by delayed resetting upon coil energization.

Each delay period is independently adjustable.

In new circuit designs or the improvement of existing controls now using two or more conventional timers, the Double Head unit offers distinct advantages.

Its compact design saves precious panel space, while the simplified wiring reduces costly interconnection.

With the addition of an extra switch block at the bottom of the basic unit, this version of the Series 7000 offers four pole switch capacity with taneous timing or two-step timing. The two-step operation is achieved by factory adjustment to your specifications.

For two-step operation, a maximum timing ratio between upper and lower switches of 3:2 is recommended.

Once adjusted at the factory, this ratio remains constant regardless of changes in dial settings. (Ex: If upper switch transfer is set on dial at 60 sec., minimum time on lower switch should be 40 sec.) This Series 7000 unit offers many of the performance features found in basic models -voltage ranges, timing and switch capacities are virtually tical. Four pole models add approximately 1-1/4" to the maximum height of the basic model, approximately 1/8" to the depth. They are designed for vertical operation only. The Surge/Transient Protection Option protects electronic control circuits from transients and surges which are generated when the timer coil is activated.

Built with a minimum of moving parts, the unit provides a fast response to idly rising voltage transients.

The accurate, precision-made device is not ty sensitive and permits the user to initiate, delay, sequence and program equipment actions over a wide range of applications under the most severe operating conditions.

It consists of a specially modified coil case, varistor, varistor cover, terminal extensions and cup washers so that normal terminations can be used. The varistor will not affect the operating characteristics of the 7000 Timer. The varistor has bilateral and symmetrical voltage and current characteristics and therefore can be used in place of the back-to-back zener diodes. This teristic also means that the coil will not be polarity sensitive.

-20 D F to + 165 D F (-29 D C to 74 D C) Storage: -67 D F to + 165 D F (-55 D C to 74 D C) Temperature Variation:

Using a fixed time delay which was set and measured when the ambient temperature was 77 D F (25 D C), the maximum observed shift in the average of three consecutive time delays was -20% at -20 D F (-29 D C) and +20% at 165 D F (74 D C). Mounting/Terminals:

Normal mounting of the basic unit is in a vertical position, from the back of the panel. A front mounting bracket is also supplied with each basic unit, for installation from the front of the panel. All units are calibrated for vertical operation.

Basic models (7012, 7022) may also be horizontally mounted, and will be adjusted accordingly when Accessory Y1 is specified in your order. Standard screw terminals (8-32 truss head screws supplied) are located on the front of the unit, with permanent schematic markings.

Barrier isolation is designed to accommodate spade or ring tongue terminals, with spacing to meet all industrial control specifications.

The basic Series 7000 may also be panel mounted with the addition of a panelmount kit that includes all necessary hardware and faceplate.

This offers the convenience of "out-front" adjustment, with large calibrated dial skirt knob. The faceplate and knob blend with advanced equipment and console designs, while the body of the unit and its wiring are protected behind the panel. Other mounting options include plug-in styles and special configurations to meet unusual installation requirements.
