Subject:
Clinton Power Station Additional Revision to Proposed Amendment of Facility Operating License No. NPF-62 (LS-94-013) _
Dear Madam or Sir:
By letter dated February 22,1996 (letter number U-602554), Illinois Power (IP)
Company proposed an amendment to the Clinton Power Station Technical Specifications (TS) to revise the setpoint for the 4.16 kV safety bus degraded voltage relays , and to revise or delete other Loss of Power instrumentation TS requirements, due to planned modifications to replace the degraded voltage relays at CPS. For related reasons, IP also proposed to change the minimum required diesel generator voltage specified in certain diesel generator surveillance requirements within the Technical Specifications. Upon initial review ofIP's submittal, the NRC issued a Request for Additional Information (RAI), to which IP responded via IP letter U-602613 dated July 24,1996. Following discussion with the NRC subsequent to IP's response to the RAI, IP determined that the proposed amendment should be revised. Consequently, by letter dated October 4,1996 (letter number U-602635), IP submitted a revision to the proposed amendment.
Following recent discussion with the NRC (Mssrs. Pickett and Lazcynick) during the NRC's continued review ofIP's proposed TS change (as revised by IP's October 22, 1996 letter), IP has decided to further revise the proposed amendment. The changes to i
the proposed amendment would revise Table 3.3.8.1-1, " Loss of Power Instrumentation,"
by (1) dividing the Function, " Degraded Voltage - 4.16 kV basis," into two separate items,
" Degraded Voltage Reset - 4.16 kV basis" and " Degraded Voltage Dropout - 4.16 kV basis," (2) re-numbering the items in the table, and (3) revising the associated notes. The l l proposed TS changes are discussed in detailin Attachment 2. Within Attachment 3 please l find marked-up pages of the proposed TS changes including marked-up pages of proposed
(- TS changes that were previously submitted. The overall proposed changes are encircled,
! and the proposed changes being submitted for the first time with this letter are additionally i indicated by triple revision bars in the right hand margin.

Also, please find Attachment 5 which contains marked-up pages of the TS Bases reflecting additional changes to the affected TS Bases pages. In a manner similar to the j proposed TS changes in Attachment 3, the proposed changes for the TS Bases, includmg :
those previously submitted, are marked such that the changes are encircled and the l proposed changes being submitted for the first time with this letter are additionally j indicated by triple revision bars in the right hand margin. An affidavit supporting the facts l set forth in this letter and its attachments is provided in Attachment 1. )
It should be noted that IP Calculation 19-AN-19, "Calcs for Functional
)
Requirements for 1st & 2nd Level Undervoltage Relays at 4kV 1 A1, IB1, & IC1,"
Revision 2 Volume C was included as Attachment 2 with IP's response (IP letter U-602613) to the NRC RAL IP then revised IP Calculation 19-AN-19 and provided the
' NRC with Revision 2 Volume D as Attachment 5 to IP letter U-602635. IP has further revised the calculation to revise the nominal setpoint for the Degraded Voltage Dropout -
' Function. The changes to the calculation are discussed in detail in Attachment 2 and IP Calculation 19-AN-19 (Revision 2 Volume E) is attached (as Attachment 4) to this letter.
The changes contained in this revision ofIP's proposed amendment do not alter IP's determination that the proposed Technical Specification c;.anges meet the criteria given in 10CFR50.22(c)(9) for a categorical exclusion from the requirement for an Environmental Impact Statement. In addition, IP has also concluded that the Basis for No Significant i Hazards Consideration, as provided in IP's Febniary 22,1996 submittal, remains unchanged. 1 i
As noted in IP's February 22,1996 submittal, the implementation schedule for the j degraded voltage relay modifications calls for installing new relays fer the Division 2 4.16 kV !
safety bus during the current outage (RF-6) at CPS. Implementation of the modifications is l part of corrective action committed to the NRC for Licensee Event Report (LER)94-005. l IP is therefore requesting that the application for amendment, as supponed by this letter, !
continue to be reviewed on a schedule sufficient to suppon planned work actisities scheduled !
to begin November 27,1996. l 1

s 2; Attachment 2 to U-602657 LS-94-013 Page1 of3 Discussion and Description of Chan-By letter dated February 22,1996, Illinois Power (IP) submitted a proposed License Amendment to change Technical Specification (TS) 3.3.8.1, " Loss of Power -
Instrumentation," and TS 3.8.1, "AC Sources - Operating." . The changes originally-proposed in IP's February 22,1996 submittal would delete Surveillance Requirement (SR) 3.3.8.1.1 which requires performance of a channel check for the Loss of Power instrumentation, revise TS Table 3.3.8.1-1 to change the Allowable Value for the Degraded Voltage Function (items 1.c and 2.c) from "23762 V and $3832 V" to "23876
.V" and to change the required number of channels for the Division 3 degraded voltage protection (item 2.c) from 3 to 2, and revise SR 3.8.1.2, SR 3.8.1.7, SR 3.8.1.11, SR
~ 3.8.1.12, SR 3.8.1.15, SR 3.8.1.19 and SR 3.8.1.20 to change the minimum steady-state voltage identified in these SRs from "23740 V" to "23870 V."
During the NRC's review ofIP's proposed License Amendment, several questions posed by the NRC reviewer regarding the proposed amendment were discussed. The NRC issued a Request for Additional Information (RAI) to docket the identified questions, and IP responded via IP letter U-602613 dated July 24,1996. Following review ofIP's response to the RAI there was additional discussion of the proposed amendment. As a result of that additional discussion with the NRC, IP revised its submittal via IP letter U-602635 dated October 4,1996, with respect to some of the proposed changes to Technical Specification 3.3.8.1. Ongoing review of the revised submittal, including recent discussions between the NRC and IP regarding the proposed changes, has prompted IP to further revise the proposed License Amendment.
Within letter U-602635 dated October 4,1996, and consistent with IP's initial position that only the reset (pickup) function associated with the degraded voltage protection relays should be addressed in the Technical Specifications, IP had proposed to add the word " reset" to the degraded voltage Function description, for items 1.c and 2.c in Table 3.3.8.1-1, " Loss of Power Instrumentation." However, in response to a comment from the NRC reviewer, IP has determined that the dropout and reset functions associated with the degraded voltage protection relays should both (but separately) be addressed in the Technical Specifications. IP therefore proposes dividing the Function, " Degraded Voltage
- 4.16 kV basis" into two line items within TS Table 3.3.8.1-1. For each line item, the Function, the required number of channels per division, the associated surveillance requirements, and a range for the associated Allowable Value (AV) would be specified under the respective headings of Table 3.3.8-1. To incorporate these changes, IP proposes to revise Table 3.3.8.1-1 such that the addition cf the Function, " Degraded Voltage Reset - 4.16 kV basis" would replace item 1.c. The present item 1.c Function,
" Degraded Voltage - 4.16 kV basis" would replace item 1.d and would be revised to read
" Degraded Voltage Dropout - 4.16 kV basis." The present item 1.d Function, " Degraded Voltage - Time Delay" would be changed to be new item 1.e. Similarly, IP proposes to revise Table 3.3.8.1-1 such that the addition of the Function, " Degraded Voltage Reset -

i Time Delay" would be changed to be new item 2.e. ,
4 l
[ The additional revision to IP's proposed TS changes also includes adding a note applicable I r to the new Degraded Voltage Reset Function as well as revising and re-numbering the !
i notes. The purpose of note "(a)" is to provide an explanation that the Degraded Voltage i l Reset Functions specified for items 1.c and 2.c are not applicable until after the release for l 4
operations (RFO) of the corresponding plant modification. Similarly, the purpose of note _
"(b)" is to provide explanation that the values specified for the Degraded Voltage Dropout i j are applicable only after RFO of the corresponding plant modification. Prior to RFO, note j (b) explains that current values are to be used. Lastly, note "(c)" has a similar purpose to l provide explanation that the number of required channels specified for the Division 3 i
- Degraded Voltage Reset is applicable after RFO of the corresponding plant modification.' !
Note (c) explains that, prior to RFO, the present number is to be used (for the current !
relay configuration corresponding to the " Degraded Voltage - 4.16 kV" Function on Table 3.3.8.1-1). ,
p .
1 Because of the additional TS changes, additional TS Bases changes are being proposed. ;
IP_ has revised the proposed changes to the TS Bases to discuss the addition of the new Function item to Table 3.3.8.1-1 and to reflect revision of other items and item numbers 1 within Table 3.3.8.1-1; Additional changes are proposed to discuss both the Degraded
- Voltage Reset and the Degraded Voltage Dropout Functions corresponding to Table 3.3.8.1-1 items 1.c,1.d,2.c, and 2.d. ;
Included as Attachment 4 to this submittal is IP Calculation 19-AN-19, Revision 2, Volume E. As noted within the cover letter, IP had previously transmitted IP Calculation 19-AN-19 Revision 2,> Volume C when IP responded to the NRC Request for Additional Information (RAI) via IP letter U-602613 dated July 24,1996. After further discussion ,
with the NRC, IP subsequently transmitted Revision 2, Volume D of the calculation in IP letter U-602635 dated October 4,1996. As further explained below, Revision 2,
- Volume E reflects changes made to the calculations to support the Allowable Values specified for the Degraded Voltage Dropout function. A complete copy of Revision 2, j Volume E of the calculation (and its attachments) is provided in Attachment 4. This revision supersedes all previously provided revisions to the calculation (and its attachments).
- IP initiated the most recent revision ofIP Calculation 19-AN-19 (Revision 2, Volume E) to address the NRC reviewer's comment that the separation (voltage difference) from the drop-out calibration lower limit to the drop-out minimum AV (as originally proposed) would have been much smaller than the separation from the reset calibration lower limit to the reset minimum AV. The reviewer considered this to be an issue wherein it may be
e :o Attachment 2 to U-602657 LS-94-013 Page 3 of3 conjectured that an instrument bias or degradation could cause the setpoint to change .
identically for the reset and the drop-out.- This could result in the reset setpoint being less than the calibration lower limit but within the reset AV lower limit, while the drop-out ,
could be at a value less than the calibration lower limit and less than the drop-out AV l lower limit. Therefore, the dropout setpoint has been revised to provide similar separation ;
for the dropout and the reset between their respective calibration lower limits and AV- !
lower limits. l l

[ Dept /Div. E/EPEDI PURPOSE
- The purpose of this Calculation is i
. To evaluate the use of an' ABB 27N undervoltage relay in the Second Level Under-Voltage (also called degraded voltage) protection scheme.
! . Determine the relay trip (drop-out) and reset (pick-up) bands based on the
- loop accuracy methods described in CI-01.00 Instrument Set-point Calculation i
Methodology (Reference 10).
- . The analytical limits (AL) for the second level under-voltage relay. pick-up are
! as follows:
1 1. The maximum pick-up voltage is equal to the minimum 4KV ESF bus i voltage under steady-state LOCA loading with the off-site voltage at the I
minimum expected value.
- 2. The minimum pick-up voltage is equal to the minimum 4KV ESF bus i voltage required to start and run the LOCA required equipment.
!' . The allowable value (AV) will also be established by this volume and this i number will be used in the Tech Spec revision which is being prepared to support the new relay settings.
- DISCUSSION '
i The second level under voltage relay scheme has a two-fold function. It 8 -
i must ensure that there is adequate voltage following the LOCA block start j initiation for the ESF required equipment to start and run. It must also prevent the i' ESF buses from transferring to the on-site source'if there is adequate voltage from the off-site source to operate the ESF equipment. Therefore the second level a under voltage relay pick-up voltage (accounting for the various instrumentation l errors) must fall between these values. In addition, we want to prevent spurious ;
transferring of the ESF buses to the onsite source and allow for minor changes to ;
j the off-site grid with out impacting the degraded voltage relay aeninaa. We have j therefore based on engineering judgment chosen to limit the maximum relay pick- .
i up to 0.75% below the 4160 volt bus 1A1 voltage found in Calculation 19-AQ-02 g
- Rev. 3 =*achment 10.2. This setting will pmvide a degree of margin below the i minimum expected 4KV Bus voltage under steady state LOCA conditions with
- the 345 Ky switch-yard at the uinimum expected value. Calculation 19-AQ-02 l Rev. 3 Attachment 10.2 lists the steady state minimum voltage at the Bus 1 A1 as l 3938 volts. 100%-0.75% of 3938 equals 3908 volts. The minimum reset point will be the minimrm voltage at the 4KV bus which will ensure that all the ESF equipment required for LOCA will start and run. The minimum voltage required by the ESF equipment will be taken from 19-AQ-02 Rev. 3 volume P Attachment i 8.1 (3870 volts). The nominal second level under-voltage relay pick-up point has j therefore been chosen to be mid way between the maximum and minimum reset-j points or 3889. We will call this nominal value NTSP. This calculation will i assure that there is adequate margin for NTSP between the maximum and l minimum allowable values when the total relay loop error is considered.

1 INPUTS II. The relays utilized in the Second Level Under-Voltage scheme will be ABB type 27N catalog number 41IT6375-HF (or 410T6375-HF which has the same characteristics) . The relay pickup range is from 70 to 120 volts, the dropout range is 70% to 99.5%, the pickup time delay is instantaneous. The drop out time delay will be set at minimum (= 0.1 sec)
The relay requires a 125 volt nominal DC source to operate. The relay will include the harmonic distortion filter. The published relay tolerances from Reference 3,4 and 5 EXPRESSED AS A PERCENT OF SE'ITING are as follows:
a) Pickup and dropout setting repeatability with respect to temperature with a constant control voltage and the relay operating in an environment where the ambient temperature could vary A % !
between +10 to +40*C is *0.4%. We will call this 28 value ATE
^ " 'I
- b) Pickup and dropout setting repeatability at a constant temperature and constant control voltage is i 0.1%. We will call this 26 value VA.
c) Pickup and dropout setting, repeatability over " allowable" de control power range is i 0.1%. The allowable de control power range for a 125 volt nominal relay is 100 to 140 V DC. The Tech l Spec requires that when AC power is available to supply the 1 battery charger the DC buses must operate between 121 and 139 yot s volts. The published DC supply error is considered linear over the operating range per Reference 10, Engineering standard CI 01.00. ;
Therefore, the published error of*0.1% can be divided by 40 volt
. allowable range. In addition, data in the ABB type test Certificate PSE :=.045 % i Reference 5 shows that this is conservative. The variation then ;
equals *0.0025%/ volt. We willcallthis 25 error PSE and -
l consider it to be *0.045% for our operating range.
.' d) The radiation and humidity effects are considered negligible i because the relays are not subjected to an environment with humidity or radiation above normal atmospheric conditions, e) The 27N relay has been subjected to 6g ZPA either axis biaxial broad band multifrequency vibration without malfunction or [
damage per ANSI /IEE C37.98 (reference 4). Therefore there is no V.L E seismic impact to the relay accuracy.
f) ABB tests indicate that there is no RFI interference effect associated with the relay. Therefore it is not considered a factor in this calculation (Reference 5).

13 The detection loop consists of the 4KV bus which we wish to measure, a potential transformer (PT) to convert 4KV to 120 volts and the ABB 27N relay.
The pts for DIV. I & II are Westinghouse PC-60 and, for DIV. III, GE ;
, type JVM-3. Both PT models have a ratio of 4200 - 120 volts and are class l
, IE. They conform to ANSI C57.13-1%8 metering accuracy class for .03 i class standard burdens W, X, M, & Y. The pts were purchased to l ' Westinghouse drawing EN005, and GE data sheet 317A6131, and S&L d
form 1815-L (Reference 1). The PT burden was established using E02-l 1 AP12 SH 11 R/W, E02-1 AP99 SH 36 R/D, E02-1 AP99 SH 38 R/U ,
i E02-1AP12 SH 13 R/V, E02-1 AP12 SH 15 R/f, and E02-1HP99 SH 107 i R/L (Reference 7), and the load data from the vendor manuals (Reference l 1). The PT burden consists of a CV2 relay, the 27N relay, a voltage j j transducer, a lamp and a voltmeter (Note: the EMTs shown on E02-
- 1 AP12 SH 13 R/V are being disconnected from the pts by mods AP- '
l~ 027,28, & 29). The total burden on the PT is 7.5VA with a possible l change in burden (caused by switching the voltmeter between phases) of 1 4 1 VA. From .the performance curve found in reference 9, we can see that
, for a change in burden of 12.5 VA the tums ratio correction changes 0.1%.
f Therefore, if the actual change is'1 VA the change in PT tums ratio (EPT) would be .008% ofrating. The curve also shows that the PT ratio correction factor should be .997. EFT :=.008% !
.I4. Two relays will be installed in DIV. I & II (one between phase AB and leNE )
one between phase BC). The relay trip functions are wired in series so i
' that both relays must trip in order for the protective action to be initiated.
, Only one relay must reset for the timer to reset, preventing transferring of load to the diesel. Reference E02-1 AP12 sheets 11 & 13 (Reference 7).
- 15. Two relays will replace the present single three phase relay in Div. III . '
The new single phase relays will monitor phase AB and. BC. The trip contacts are wired in series. All the elements must sense a degraded voltage for the protective function to be iwtiated. Only one relay must reset for the timer to reset, preventing transferring ofload to the diesel.

Reference # 10) for deterrnining critical set points based on instrument errors.
This methodology is statistically based. 'Ihe desired probability for relay actuation
-is 95% (per Reg. Guide 1.105 -Reference # 11). In order to determine the 95%
probabihty ofeither 2 relays actuating together or 1 of 2 relays resetting, the table Attachment I was set up.

The probability that two will actuate together was determined by muhiplying the j probability ofeach of them together and plotting that curve accordingly. In this case that meant squaring the probability ofone relay (since the probability for both i relays is the same). The point on the Table in attachment I which equaled .95 was then found. This came out to be 1.96.-
5 To determine the same a multiplier for when only one of the two relays needed to
, change state, the probability that the relays would fail to actuate was considered.
, To do this, I minus the probability squared was tabulated (attachment 1). From
! this table the value for 95% confidence was found. This corresponds to a value of 2
.76.

Therefore, the 1.96 6 is to be used for a 95% probability that two relays will actuate together and 0.76 8 that one of the two will reset.
i M.4a Two 27N relay contacts (in series) are required to initiate the time delay relay and the subsequent protective action. We have, therefore, I determined that for a 1.% 6 deviation about the set point the relay loop )
will activate with 95% confidence level. We will call this Accuracy drop

M.4b Only one of the two 27N relay contacts (in series) are required to reset the time delay relay and subsequently prevent the buses from transferring to the diesels.

The drop-out allowable (3847.62) limit and the setting limit (3848.92) are both below the drop-out setting of 3862.
gg The critical requirement, from a plant safety standpoint, is that all the equipment required to support the LOCA block start receive sufBeient voltage to start and run. Therefore the critical degraded voltage relay parameter is that the relay must reset at or above 3870 volts. This'is equivalent to the relay minimum reset accounting for the appropriate relay errors.
The following table listing settings and analytical limits will be used as inputs for a Tech. Spec. change and the procedure for calibration of the relays. The vohage at the 120 vok level reflects the required voltage at the 4KV bus as scaled (transformed) by the PotentialTransformer. The ratio of the 4KV voltage to the 120 vok levelis 34.895:1. The Degraded Vohage relay senses and is calibrated for voltage at the 120 Voh level.
'Ibe calibration limits are established by drawing E02-1 AP04 sheet 001 and in the CPS calibration procedure. 'Ihey are used as inputs to this calculation. The calibration limits are *0.04 vohs. They are taken from section M3b.2 and are added and subtracted from the relay set-point at the 120 voh level. The 4 KV level value is equal to the 120 vok value times the PT ratio (35*0.997).

! INTRODUCTION -
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 overvoltage relays, type EgN. catalog series 211U and 411U.
i The relay is housed in a case suitable for conventional. semiflush panel mounting.
A11 connections to the relay are made at the rear of the case and are clearly numbered. . Relays of the 4117, and 411U catalog series are sinflar to relays of the 211T, and 211U series. Both series provide the same basic functions and are of totally drawout constewotion; however,.the 411T and 411U series relays provide 4
integral test facilities. Also, seguenced disconnects on the 410 earles prevent
- ' nuisance operation during withdrawal or insertion of the relay if' the norpally-open i contacts are used in the application. -
Basic settings are made on the front panel of the relay, behind a resovable. clear plastic cover. Additional adjustment is provided by means of calibration potentfo-
.! meters inside the relay on the circuit board. The target is reset by means of a i 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 befotu energizing.
l
- 2. Apply only the rated control voltage marked on the relay front panel. The proper polarity must be observed uhen 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. See the section on testing ,
l for additional information. l
- 5. The entire circuit assembly ,of the relay is removable. The unit should insert emoothly. Do not use excessive force. ,
I
- 6. Follow test instructions to , verify that the relay is in proper working order.
CAUTION: einoe troubiechootthe entaiis Norking with energized equfpment, cere should be taken to avoid personal shock. Only competent 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.

For relays with dual-rated control power:, before energiring, withdraw the relay from
- its case and inspect that the movable Tink on the lower printed circuit board is in i the correct position for the system control voltage. (For units rated 110vdc. the i link should be placed in the posit.fon mat-kod 125vdc.)
l- These relays h' ave an external resistor wired to terminals 1 and 9 which must be in place for normal operation. The resistrr is supplied mounted on the relay.
i These relays have metal front panels witach are connected .through printed circuit.
j 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.
l i 3. SETTINGS 1 PICKUP i The pickup voltage taps identify the voltage level which the relay will cause the j output contacts to transfer.
OROPOUT i The dropout voltage taps are identified as a percentage of.the pickup voltage. Taps
- are provided for.70s, 80%, 90%, and 99K of pickup, or, 30s, 40%. 505-, and 60X of
~

! Note: operating voltage values other.than the spectffc values provided by the taps
- 8 can be obtained by means of an internal adjustment potentiometer. See section on j testing for setting procedure.
6
! TIME DIAL j The time dial taps are identified as 1,2,3,4,5,6. Refer to the time-voltage charac-j teristic curves in the Application section. Time dial selection is not provided on l relays with an Instantaneous operating characteristic. The time delay may also be i varied from that provided by the fixed tap by using the internal calibration adjust-j ment. ,
l'
! 4. OPERATION IMOICATORS 1
i 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 trhe relay. See Figure 4 for the operation of this indicator.
Units with a *-L" suffix on the catalog number provide a green led to indicate the presence of control power and internal power supply voltage.

t TESTING ,
- 1. HAINTENANCE AND RG4EWA1. PARTS Ho routine amintenance 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 circuit descriptiop booklet COT.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 Crawout 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 putt 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 Isads at the rear vertical circuit board. This rear board.is marked for easier identification of the connection points, s Important: these relays have an' external resistor mounted 'on rear terminals 1 and 9.
In order to test the drawout unit an equiv11ent resistor must be connected to p-terminals 1 & 9 on 'the rear vertical circuit board of the drawout unit. The i 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 conclusion of testing.
Test Plug:
A test plug assembly, catalog number .400X0002 is available for use witly. the 410 ceries 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 18 7.7.1.7-8
. for dotatis 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 8e sure to take all necessary precautions if the tests are run with the main circuit i energized.
The built-in test is provided as a convenient functional test of the relay and assoc-lated 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.
