• NON-SAFETY SYSTEMS, INCLUDING QUALIFICATION OF ISOLATION DEVICES During a telephone conversation between.R Scholl, SEPB, USNRC and RA Vincent, et. al., Consumers Power Company on October 6, 1981, Consumers Power Company was requested to respond to several questions concerning SEP Topic VIT--1.A for the Palisades Plant. This topic has been the subject of several letters between CPCo and the NRC, the most recent of which was a revised NRC evaluation of this topic dated August 28, 1981. The attached information is provided in response to the informal questions as .well as the conclusions of the August 28, 1981 letter. In light of the information contained within the attached report, tw:o additional comments are appropriate.

First, the report references a letter from the NRC to CPCo dated March 1981 in which a maximum flood level of el.597 .l' is given for Palisades. Use of this flood level in the attached report does not reflect *cPCo acceptance* of the 597.1' value, but is merely used to show that flooding concerns do not exist for the equipment in question.

• Second, the report discusses CPCo plans to reroute cables associated with three analog circuits which do not meet the separation of* IEEE 384-1977.

This discussion should not be considered a formal commitment at this time. It is expected, however, that this item will be addressed as a potential backfit item in the final Integrated Assessment Report. /Jo3'S Brian D Johnson Senior Licensing Engineer .s 1/ro CC Director, Region III, USNRC NRC Resident Inspector -Palisades s11110: _ _f _] OCK

• PALISADES PLANT RESPONSE T.O-NRC *QUESTl019"S SEP TOPIC VII-1.A During a telephone conversation on 10/6/81, the NRC requested that the sumers Power Company provide a response to certai.n questions.

concerning the subject SEP topic. In addition, letter D M Crutchfield to DPHoffman dated 8/28/81 states that certain isolation between the Reactor Proection System (RPS) and the non-safety logging systems such as the Tennecomp Data logger System (DLS) *and the Fischer & Porter plant. computer is unacceptable and requires replacement or justification for continued use. This letter serves to both the telephone requests and the requirements* established in the subject letter . TELEPHONE REQUESTS Question #1 How are the circuit cards for the input isolation circuits mounted in the field remote station? Does this mounting lend itself to common-mode failures of the isolation devices? Are they separated per IEEE .384-1977? Response .to Question #1 The isolation devices for the digital inputs to the DIS are not located in the field remote station. The digital inputs to the DLS are isolated by relay contact in the RPS. This is acceptable is.olation according to IEEE 384-1977 Paragraph 6.2,2.2 "Acceptable Isolation Devices". Furthermore, in the mentioned 8/28/81 letter the NRC states that "Relay contact isolation is an acceptable means of isolation between RPS functions and control and non-safety equipment." Given the various isolation methods and separation techniques employed in the analog circuits, however, the analog inputs to the DLS need to be discussed in detail. Attachments

1. 1, #2 and #3 show the analog input cards are mounted in the Field Remote Station (FRS) intra-cabinet assembly.

The cards are mounted in chassis Fll and a separation of approximately one-half inch exists between cards. Although only one-half inch exists between these cards,_ a common-mode failure involving these cards has no significant impact on the RPS and its ability to perform its safety-related function for reasons given in the following paragraphs. -*

• 2 Attachment

1. 4 shows the analog signals that input to the DLS. Only the eight neutron flux safety signals A through D, uppers and lowers) are redundant signals. All of the other analog signals represent non-redundant, diverse primary system parameters.

In the following three paragraphs, the three t;r,pes of analog inputs are discussed in detail. During the discussions, emphasis is placed on classifying these types of inputs and on the impact of a common-mode failure within the isolation devices. Emphasis is also placed on the degree of channel separation (between DLS input terminating points and the control room panels) that exists within each input type.

• In the "Response to Question #3", an overall view of the signal routing to the FRS is presented for both digital and analog signals. In the response, emphasis is placed on the existing degree of analog signal separation between the various types of inputs. The first type of analog input is identified as Class lE all along its route from the RPS panel to FRS 1 in the Tennecomp DIS. DLS inputs of this type are: steam generator A pressure, steam generator B pressure, primary coolant loop inlet temperature, primary coolant loop outlet temperature and reactor coolant flow. These DLS analog inputs are considered Class lE since they are not isolated in the RPS. Isolation for these signals is provided in the DLS analog input conditioning circuitry. (The adequacy of this to perform effective isolation is discussed in the-"Response to-Requirement

1. 1" below.) These DLS analog inputs represent diverse primary system parameters and all originate in safety Channel A. (See Attachment
2. 4.) Therefore, a common-mode failure in the isolating circuit cards could only effect one channel of safety-related equipment.

These inputs are, relative to each other, redundant and need not conform to the separation criteria as defined in IEEE 384-1977. The second type.of analog input represents signals that are non-redundant (relative to each other) and are non-Class lE as well. As shown in Attachment

1. 4, inputs of this type are: steam generator A water level, steam generator B water level and pressurizer pressure.

These DLS inputs originate in safety-related circuitry (in panels other than the RPS) and are identified as non-Class lE throughout. Therefore, adequate isolation devices in the FRS are not required.

• Nevertheless, isolation circuitry identical to that used for the first type of analog input*, is utilized by this type of input. As shown in the Attachment, these signals also represent diverse primary system parameters.

Since these inputs are non-Class lE and non-redundant (relative to each other) they are not subject to the separation criteria as defined in IEEE 384-1977. The third type of DLS analog input is that of neutron flux safety. These eight inputs (Channels A through D, upper and lower) represent redundant nals to the DLS. These inputs are classified as non-Class lE, however, since adequate signal isolation is incorporated into the output of the RPS panels. These signals are outputs from buffer amplifiers located in the Nuclear ments System linear power channel drawers located in tne RPS panels. The buffer amplifiers (one per neutron flux safety channel) serve to isolate and protect the power channel circuits from various types of output cable faults. tachments

1. 5 and #6 provide a vendor (Gulf General Atomic) description and schematic diagram of the buffer amplifier circuitry.

Regarding the i.solation capability of the buffer amplifiers, FSAR Paragraph 7.4.2.2(8) states "All output channels are buffered so that accidental connection to 120 volts a-c, or to.channel supply voltage, or shorting individual outputs does not have

• 3 any effect on any of the other outputs." Since adequate circuit isolation exists in the power channel drawers, adequate isolation in the FRS (although utilized as described in the preceding paragraph) is not required.

It should be noted that the adequacy of the buffer (operational) amplifier circuits to isolate is discussed further in the "Response to. Requirement

1. 3". The neutron flux safety signals are redundant and are non-Class lE since they are adequately isolated in the RPS. Since they are isolated, the flux signals need not be separated from each other. Question #2 , What is the flooding potential of the isolation devices? Response to Question #2 As shown in Attachments 1, 2, 3, 7 and S, the DIS analog input circuitry is located in Chassis Fll in the FRS intra-cabinet assembly.

Attachment

1. Sa shows that the cabinet internals are installed behind sealed doors which are hinged to both the front and back of the cabinet. Attachment
2. Sa states that all cabinet doors and removable panels are to be sealed per NEMA 12. Although these cabinet doors are louvered on the top and bottom to provide essential component ventilation throughout the cabinet height, the cabinets are esentially splash-proof.

The FRS is located in the cable spreading room at Elevation 607.5 feet. The FRS is, therefore, installed at an elevation of 10.5 feet above the probable maximum surge level of 597 feet as documented in letter D M Crutchfield to DPHoffman dated March 20, 19Sl. In addition, letter D M Crutchfield to DPHoffJ;nan dated April 30, 19Sl summarizes a technical evaluation (based on specific plant reviews) of the susceptibility of the switchgear room to flooding in the event of failure of non-Category 1 systems. The letter states that worst-case flooding :ln the switchgear room (which would occur from a break in the 6-inch fire system piping) can be handled adequately by floor drains with no damage to existing motor control centers located in the room. The aforementioned letter notes that the motor control centers are mounted on pads three to four inches above the floor. Since the Tennecomp FRS is also mounted approximately three to four inches above the floor, it also should experience no damage resulting from the break. It should also be noted that no high energy lines pass through the switchgear room which could increase the probability of flooding. Question #3 How do the cables run from the RPS to the FRS? to Question #3 Attachment

1. 9 has been included to better illustrate the digital and analog cable routinr, between the RPS and FRSl; with emphasis on the degree of separation between the various types of DLS inputs. As can be seen in the Attachment, the digital signals route to the control room auxiliary Panel Cl3 and on to the FRS in separate cable for each channel. The cable as shown is all non-Class lE since adequate isolation devices (relay contact) exist in the RPS.

• 4 The raceway used for these cables between the control room and FRsl is idual, separate conduit. For example, the Channel A and Channel B cable routes in conduit Xl480, the Channel C cable runs in Conduit Xl481 8.l'ld the Channel D cable runs in Conduit XV1482. This raceway is separate from Class lE raceway in the area. Regarding the analog signals, it can be seen that all of the non-redundant signals (all analog signals except neutron flux safety) route from the control room Panel Cll to FRSl in a common cable. All of these represent diverse primary system parameters and originate from safety Channel "A" if not from control-grade (non-Class lE) circuits.

AB a result, a common-mode failure involving this cable should, at the worst, affect only one safety channel of two or more safety parameters. Including both the Class lE and non-Class lE signals in the same cable, however, results in the non-Class lE signals being classif:t-ed as "associated circuits".* Therefore, in accordance with IEEE 384-1977 Paragraph 4.5.1(1), the cable routes from the in-containment transmitters (for non-Class lE pressurizer pressure and steam generator A and B level) were evaluated to ensure that these three signals were associated with Channel A only while routing to their non-Class lE current loop circuitry in the control room. As a result of these evaluations, it was observed that all three signals do, fact, route in raceway that is shared with cables from safety channels other than "A". For example, the non-Class lE pressurizer pressure cable routes with the Class lE pressurizer pressure signal from safety Channel B. The steam generator A non-Class lE level signal routes with the Class lE level signal from safety Channel C and the steam generator B non-Class lE signal routes with the Class lE level signal from safety Channels B and D. Given the aforementioned channel separation violations, it cannot unequivocally stated that failures in the common cable would affect only one safety channel as those involved in the design of the RPS/DLS interface had envisioned. Attachment

1. 9 also shows the *redundant analog inputs to the FRS. These inputs are the eight neutron flux safety signals (Channels A-D, uppers and lowers). AB can be seen, these are non-Class lE and 8.re transmitted in cable separate from the other analog ?ignals. The neutron flux signal common cable that transmits the signals to the FRS, however, runs in the same raceway as the cable that carries the other analog signals to the FRS. As a result, the isolated non-Class l neutron flux safety signals become "associated circuits".

Since adequate isolation exists in the RPS for these signals, however, these signals do not present problems similar to that described in the preceding paragraph by associating with safety channels other than "A" during their non-Class lE routing. It should be noted that IEEE 384-1977 Paragraph

4.5.2 requires

that associated circuits be qualified to IEEE 383-1974. It is the opinion of the Consumers Power Company that qualifying these cables as such would not significantly enhance the safety of the plant since all of the_ analog signals are either non-Class lE or, if Class lE, are non-redundant. A common-mode failure in this cable should affect only non-safety circuits or Channel A only of the safety-grade circuits .

• 5 If the evaluation of the non-Class lE cable routes from the pressurizer pressure and steam generator A & B level transmitters had shown that these non-Class lE cables were routed with their respective Class lE safety Channel* A counterpart, then it could have been that a common-mode failure of the FRS input cable would effect non-Class lE or Class lE safety Channel A circuits only. As a result, the Consumers.

Power Company plans to reroute these three non-Class lE signals such that they either follow safety Channel A raceway only or they are physically disassociated with the Class .lE inputs to the FRS

• Finally, it should be stated that the installation of the Tennecomp DLS did not resUlt in degrading the existing degree of channel independence and separability at the plant. Regarding the analog inputs, the FRS utilizes the same inputs that were formerly routed to the since-removed Hathaway oscillograph.

The digital inputs to the FRS are simply taken off of existing inputs to the plant's event recorder. Should a possibility exist for a comnion-mode failure to affect more than one safety channel, it results from channel separation violations that occurred prior to the DLS installation as noted in the preceding paragraph. Question #4 Have the zener diodes, which are presently installed in the DLS input isolation circuitry, been Response to Question #4 Regarding specific tests of the individual zener diodes, it should be stated that diode manufacturers conduct routine sample tests to ensure that a certain percentage of their products conform to acceptable standards or ratings. The ratings for zener diodes 1N5244 are given in Attachment

1. 10. (Note, Attachment
2. 11 identifies the DLS analog input circuit diodes as Type 1N5244B.)

As can be seen in Attachment

1. 10, the 1N5244 diode is rated at a breakdown voltage of 14V which corresponds to the Tennecomp description (see
2. 12, Page 3) of the diodes' operating characteristics.

Since the performance of solid state electronic components is so dependent on thermal conditions, the component's temperature coefficient provides one of the best indications of its dependability. Attachment

1. 10 (Pages 2 and 3) gives the range of temperature coefficients for diodes of various voltage ratings. (Note, Page 3 indicates that 90% of the units are in the ranges indicated.)

The maximum temperature coefficient for a 14 volt zener diode is +0.082%/0 c. Therefore, even if the diode's temperature were to rise to the design operating temperature of the analog input system which is 63°c (refer to attachment lla), the zener's breakdown voltage change would only be (+0.082%/0 c)(63-25)0 c = 3.12%. This change would result in a new breakdown voltage of (14V)(.0312)+14V=l4.4V . . Although the operation of the diode is a function of temperature, manufacturer's tests have shown that the breakdown characteristic is relatively stable and dependable over the analog input system desie;u temperature range. It should be noted that this maximum temperature of 63°c exceeds the highest expected temperature for the switchgear room and the highest temperature expected in FRSl cabinet.

• 6 Question #5 What is the effect of a short-to-ground in the cable that connects the RPS to the DIS? Response to Question #5 Attachment

1. 12 provides calculations which determine the effects of several, more-probable circuit malfunctions; one of which is a short-to-ground of the cable that transmits the RPS signal to the FRS in the Tennecomp DLS. As can be seen in the Attachment, the effect ori the RPS is insignificant for each of the postulated malfunctions.

This insignificant impact is primarily a function of the following circuit features:

1) the transmitter's ability to act as a constant current source over a wide range of load resistance, 2) the RPS current loop operates "floating" abov.e. ground and 3) the large ohmic value of DLS input thermistors . It should be noted that .Attachment

1. 12 deals with short-circuits only since the more probable postulated open circuit malfunctions in the DLS input circuitry or in the RPS/DLS cable would result in simply disconnecting the acditional load on the RPS loop which would be compensated for by the transmitter.

LETTER REQUIREMENTS Requirement

1. 1 The isolation devices used to isolate the RPS analog signals from the Tennecomp data logger, with the exception of neutron flux safety channels, do not meet IEEE 279-1971 Paragraph 4.7.2 requirements.

Response to Requirement

1. l As described in the "Response to Question #1, only certain analog signals are Class lE as they input to the DLS. These are the only signals that require effective isolation in the DLS .input circuitry.

IEEE 279-1971 serves as the current licensing criteria for isolation devices. Paragraph 4.7.2 of standard states: "The transmission of signals from protection system equipment for control system use shall be through isolation devices which shall be classified as part of the protection system and shall meet all the requirements of this document. No credible failure at the output of an isolation device shall prevent the associated protection system *channel from ing the minimum performance requirements specified in the design bases.

• 7 Examples of credible failures include short circuits, open circuits, grounds, and the application of the maximum credible a-c or d-c potential.

A failure in an isolation device is evaluated in the same manner as a failure of other equipment, in the protection system." The introductory paragraph of Regulatory 1.89 states that 10CFR50, Appendix B, Criterion III requires that design control measures provide for verifying the adequacy of a specific design feature by design reviews, by calculational. methods, or by suitable qualification testfng. The adequacy of the DLS analog input isolation circuits has been evaluated by review and calculation on a post-design basis. In accordance with IEEE 279-1971, the effects of credible including short circuits, open circuits, grounds and the application of the maximum credible potential have been evaluated in Attachment

1. 12, Pages 1 through 5. (Note, for open circuits, refer to the "Response to Question #5". ) As can be seen in the attachment, these failures have no significant impact on the safety-related RPS. The Attachment
2. 12 calculations address failures at the output of the DLS isolation circuitry as well as in the cable that connects the RPS loop to the DLS input circuits.

Requirement

1. 2 There are no isolation devices between the RPS primary flow and steam generator pressure channels and the Fischer and Porter plant computer.

Response to Requirement

1. 2 In letter RAVincent to D M Crutchfield dated June 29, 1981, the Consumers Power Company stated that "Although analysis shows minimal effect on the RPS due to the postulated most severe credible failure of "tying" two inputs together at the multiplexer, additional isolation circuitry needs to be installed.

The plant computer 100 ohm input resistors were not installed specifically for the purposes of isolation.!1 In light of the NRC statement in the 8/28/81 letter to DPHoffman that relay contact isolation is acceptable, the isolation capability of the Fischer & Porter input circuitry was further evaluated. As can be seen in Attachment

1. 13, the Fischer & Porter input cuitry employs two relay contacts (designated as Kl) to switch the analog input into the analog-to-digital converter at precise points in time. In effect, these contacts isolate the analog input signals from the plant computer.

T'nerefore, additional isolation circuitry is not required. It should also be noted that the reactor coolant flow input to the plant puter fs from safety Channel A while the steam generator pressure inputs (from both steam generators) are both supplied by safety Channel B. Although a review of the circuit schedule reveals that the cable raceway which transmits the reactor coolant flow signal is separate from the raceway that the pressure signals (which would be expected since these are safety-related Class lE signals), the computer inputs do not conform to IEEE 384-1977 they terminate in a common cabinet compartment on a common terminal strip. Although these RPS inputs are not separated in accordance with the most strict requirements of IEEE 384-1977, an analysis in accordance with Paragraph 5.1.1.3 of the standard (see Attachment

1. 14) shows that, in the case of postulated credible failures, the effect of one loop upon another (or others) is insigni-ficant. *

• 8 It should also be noted that the purchase specifications for the cable that transmits the three RPS inputs to the Fischer & Porter computer require that these cables be capable of passing the vertical flame-resisting test in dance with IPCEA Standard S-19-81. According to the vendor's specifications, the cable was flame tested according to the referenced standard.

In addition, these cables are environmentally qualified as Class lE as described in Revision 2 to the October 1980 "Environmental Qualification of Electrical Equipment" report. Requirement

1. 3 Use of Model A709C operational amplifier as a isolation buffer device as defined in IEEE 279-1971 is questionable and requires further evaluation as Class lE equipment.

Response to Requirement

1. 3 As was the case with the DLS analog input isolation circuits, the adequacy of the A709C operational amplifier circuitry to provide effective isolation can be demonstrated by review and calculation.

In accordance with IEEE 279-1971, the effects of credible failures including short circuits,_open circuits, grounds and the application of the maximum credible have been evaluated in Attachment

1. 12, Pages 6 through 8. As can be seen in the Attachment, these fai,lures have no significant effect on the safety-related RPS, a . I -c -* . ( ---I I J I J I

1. 5 Page 1 of 2 Gulf General Atomic Dual Linear Power Channel Model NP-6 Instruction Manual increased to the level of the bistable trip without interferring with the normal protective action, i .. e. , an increasing flux cursion will still cause a bistable trip action even though the TRIP-TEST is operated.

The TRIP-TEST control is a combination switch and potentiometer. The magnitude of the test current increases as the TRIP-TEST knob is advanced in a clockwise .direction. R24 controls the maximum TRIP-TEST current and is adjusted to make use of nearly the entire rotation range of the TRIP-TEST potentiometer. The magnitude of the test current depends on channel sensitivity. However, the setting of R24, TEST CURRENT RANGE ADJ is not at all critical to the channel's proper operation.

2. 2 Buffer Amplifiers ELJ-147-1121 Because various external devices require low source ance signals from within the linear power channel drawer, buffer isolation amplifiers have been included to prevent the destruction of vital circuits by various types of output cable faults. The buffer amplifier board consists of four non-inverting, unity gain, operational amplifier circuits.

The following discussion will consider only one (Al) of these four identical circuits. Circuit board pin #4 is groui;ided, while the input signal is applied to circuit board pin #2. Resistors R2 and R4 attenuate the signal by 50% to insure that the "common m=>de" voltage limit of the monolithic amplifier is not exceeded. Diodes CRl and CR3 insure that the ma.*dmum "Differential Mode" voltage could be only one diode's forward voltage drop or about 0. 6V. Diode CR2 and the zener diode VRl, insure that the "common mode" voltage cannot exceed about 7. OV at either input to ampli!ie r Al. The feedback network composed of resistors R6 and RI set the gain of Al. The selected ratio provides a gain of . two that will just offset the 50% loss due to the input attenuator, and thus provide an overall circuit gain of unity. The output circuit contains a 1 /10 ampere fuse (Flj and two 1N4005 power rectifier diodes (CR4 and CRS connected to the &. TONR 73.:..81 Attachment

1. 5 Page 2 of 2 , Gulf General Atomic Dual Linear Power Channel Model NP-6 Instruction Manual positive and negative power supply lines. Normally these diodes are reverse biased and contribute negligible loading tu the amplifier.

If however, an output cable fault tries to drive the amplifier output more than 15 volts from ground in either direction, one of the power diodes will turn-on conducting sufficient current directly to the power supply lines to blow the output fuse (F 1) and disconnect the defective external circuit. 2. 3 Power Summer and Subchannel Deviation ELJ 147 ELJ14 7-0010 The power summer is made up of three subcircuits that utilize the two subchannel flux signals (Va and Vb) to derive an average output (V AVG) for the bistable trip inputs. The first of these three, subci:tcuits, amplifier A2, is connected as a signal averager. Input signals Va and Vb are applied through switch, SS to input pins # 10 and #8 of the "Power Summer" board. Resistors R9 and RIO are connected to pin #2 of A2 which, because of negative .feedback, has become a virtual ground. Therefore iR9 v = a R9 and iRlO = vb RIO Because .the total current. entering or leaving a node must equal zero and also because the amplifiers input current is negligible, the sum of these two input currents must leave the node through the parallel feedback resistors Rl4 and RIO. i. = -ifb = input Rf b = iR9 + iRlO Rll X Rl4 Rll +Rl4 J.f 3 "t ...,. *.r_,. . .. o( ; I l I ' I* I .. .

7.4.1 General

Tennecomp Systems, Inc 1978 Technical Information and Instruction Manual for the Data Logger Sys*tem Volume II-Maintenance Part 7 -FRS Analog inputs to the Field Remote Station are conditioned, converted to digital values, and compared with appropriate alarm limits by several pieces of equipment in the field remote station cabinet. The input connectors are wired directly to terminals of signal ditioning cards in panels and Fll. T.he conditioning card provides protection against high voltage surges overloads

• . It also provides relays which disconnect the input wires from the input to the analog-to-digital converter (ADC) substitute a precision ADC calibration voltage. Each analog signal leaves the ditioning card at the edge connector and is carried through a shielded twisted pair_ to a relay multiplexer input card in the ADC chassis, panel Fl2. The multiplexer card has a low pass RC filter for each input signal and relays to connect the signal to the common ADC input bus. The ADC is controlled by the microcomputer system, panel F9, through an interface which permits th2 microcomputer to select an inp.ut signal for conversion-and the amplifier gain to be L1Sed. The microcomputer receives a digital value for the selected channel in binary code. This value is compared in the microcomputer with binary limit values previously transmitted from the CCS *. If the input value is out of limits,the FRS advises the CCS over the serial communication lines. If the selected analog *input channel has been assigned to a PRE/POST history.group, its binary value is stored in core memory by the microcomputer.

An analog input may have its binary value returned to the CCS over the serial communication lines if it is a member of a logging group or if a printout of its value has been requested.

7.4.2 Detailed

Description 7.4.2.1 Signal Conditioning Signal conditioning cards for up to 60 customer channels are contained in panel Fll, drawing 113-002815-001. The first card position is used to hold 4 required for thermocouple referencing and permanent calibration. See "CALIBRATION" section. If more than 60 customer channels a.re required, a *second conditioning crate is installed in panel FlO. It is the purpose of the signal conditioning card to provide protection to the ADC from overloads which may be applied to input wiring. A second function of the conditioning card is to provide signal stitution calibration of eac:h ADC channel. The conditioning circuitry. is best understood on Tennecomp drawing For all input signal ranges below 10 volts full scale, Rl and R2 are lK (nominal) positive temperature coefficient thermistors. R3 is not used. The .01 mf capacitor filters high frequency transients. 01 and 02 are* zener diodes which break down if the normal mode voltage on an input 7-8

This current heats the thermistors and within 1/2 second their resistance increases to limit the current to 6 ma. The ADC can accept* common mode voltages of up to 200V. Should the common mode voltage exceed 200V, bipolar zener Zl will*break down through Dl and/or D2, l imi ting the common mode seen by the ADC to 200 volts. Rl and R2 again act to limit current. The relay shown is used to swtich the ADC input from the field input to a calibration voltage. 7.4.2.2 Detailed Conditioning Circuitry

-10 volts or less full scale Actual circuitry used on all conditioning cards for lOV fu.11 scale or less is shown on schematic 114-002815-000. Component location and values are shown on 141-002815-000. The first sheet of logic shows input circuitry similar to 161-002815-000. R12, R15, R18,.*and R21 correspond to R3 and are omitted. R6-R9 are omitted as these would be required only for sensing current inputs. Sheet 2 of the logic diagram shows the elements required to support calibration and gain assignment. This logic is connected to the computer through an analog conditioning interface (see information on panel F9). The four channels connected to any one card must be of the same input range. Rl through RS are 0.1% resistors selected to provide a voltage 903 of full scale when lOV is applied between CALSIG and CALCOM. Jumpers 11 P 11 are installed, as is W2. W2 selects calibration for one analog panel at one time. For additional details of calibration see 11 CALIBRATION 11* Jumpers are selectively installed (as shown on 141-002815-000) to provide the appropriate ADC gain code for the input signal range assigned to the card. The microcomputer reads this gain code through its analog conditioning interface and sends this code to the ADC through its face. This technique permits input ranges to be changed for any channel group on one conditioning card by replacing the conditioning card with one for the desired new range. No changes in the microcomputer program are required to accommodate the input range change. 7 .4 *. 2.3 Detailed Conditioning Circuitry -120V input The voltage attenuator shown on 161-002815-000 for the 120-volt range was reconfigured to achieve proper operatiOn with the ADC. R2 was replaced with a fuse which opens on overloads applied to the 11 low 11 input terminal. Rl and R3 form a.100:1 divider.* All other components perform as on the lower -voltage boards. Details of the 120V conditioning logic are shown on drawing 114-002856-000 and physical component location is shown on 141-002856-000 .. Sheet l of 141-002856-000 shows input circuitry. RlO and Rll correspond to Rl on 161-002815-000, Rl2 corresponds to R3, and the network forms a 100:1 divider. This ratio requires an ADC range of 1.2 volts ful1 scale, and the balance of the card is set up for that range. R6 through R9 are not used. 7-9

1. 13 Page 2 of 2 4. 2. 8 Multiplexer Fischer & Porter Co Series 3000 Data System Instruction Manual CF Co Vendor File #Ml-PA, The ha.sic function of the Multiplexer is to progra input signals to the measuring system and to each input point.

Reference:

Schematic SC 3 0-15 42 SC30-1545 / The Multiplexer circuit card cons is ts of ten relay channels. One side of all relays are common and connected to the output of one Source Driver Switch. The other side of each individual relay is in.dependently connected to the output of an individual Typer Driver Switch for.the sink drive circuit. The relays have been specially selected for low level multiplexing tion and generate a maximum of 7 microvolts of offset for 100% duty cycle. Diode CRl, across the relay coil serves as arc SUJ:>pression while diode CR2 in the "source driver" side of the relay is used for steering. The contain 2 sets of form A contacts. These contacts are used for the positive and negative side of the input signal thru a filter network. The input data. is connected from* the input termipal strips to these data contacts. The output of the data contacts are combined iri groups of ten and are routed to the Analog-to-Digital Converter. r . Thus, via the means of upper and lower driver control, the vidual relays are energized sequentially or selectively as the need mands. The relay coil is rated to operate at 14 VDC; contact ratings are 0.2 amperes. + +IS + + + +IS ;.(. -Y'L_ .. TOAOC SOURCE DRIVER e-:,-.. '"':"..., l._ ... .....,, .........

u"-C. ---INSTALLATION .' ' b) High level analog signals (1 volt to 10 volts) 'are transmitted over twisted pairs which may be cabled with other pairs carrying .a similar age level and current levels less than 100 MA. Shielding is 'not required : except as noted be low. ", . '* c) Analog signals are not transmitted in the same -cable as digital signals. d) Analog signal cables are located at least six feet from a parallel length of AC power cable and from AC machinery. e) If signal cables are located in a high electromagnetic field area, they are run in ferrous conduit which is insulated from ground at the nal source end only. The conduit is nG:>t connected to the sys tern cabinet. f) If signal cables are located in a high electro-static field area, or close to AC power cables or digital signal carrying cables, they may be constructed with a conducting shield insulated with an overall jacket. Provisions are made to connect the shield to ground or to the computer (but not both) at the time of system startup. g) Digital signals are transmitted over twisted pairs which may . be cabled with other pairs carrying like signals. The cable does not carry AC power'. Shielding is not required. h) Pulse inputs are transmitted in the same cable as other digital signals. Twisted pairs are required.

2. 3. 3 AC Power Wiring a) It is recommended that system power should be provided from an independent isolation transformer located as close to the system as practical.

The transformer primary shield should be connected to the primary low side and the secondary shield connected to the system ground. b) A circuit breaker is connected between the isolation transformer and the system AC input connections. c) The isolation must not supply power to any device other than the system cabinet. Peripheral devices such as typewriter, card punches, etc., must be connected to other power sources. d) The system requires 11 7 volts AC +/-1 0%, .6 0 Hz . I rlf!.u.a.
