ABSTRACT This report contains the descriptions of Maximum Credible Fault Tests performed on the Validyne Model CM249'-
02, class lE Isolator, on July 22, 1987. The tests demonstrated that a 120 Vac, 60 Hz., 20-Amp f ault applied to the output of the CM2 4 9-Q2 does not degrade the isola ter saf et y-related input signal beyond an acceptable level. A fault on the non -lE output side of the isolator causes protective fuses to open, preventing fyrther component damage. Factory rework can restore f ault-damaged CM249-02
~
units to normal operation.

Those shown with an asterisk (*) also signed the data sheets and oscillog::aphs as witnesses to the tests.
2.2 Prior to performing the Fault Tests, the Qualification Test Procedure, QTP621, was reviewed for clarity and ;
eccuracy. Only two corrections were indicated: !
Section 1 on Sheet 2 said CM249-Q2 Carrier Demodulator. This was changed to read CM249-02 Carrier Modulator.
Section 1 on Sheet 2 referenced letter NE-07-006. This was changed to read letter NE-87-0061. These two corrections have been incorporated and the QTP621 has been released as a NO CHANGE revision.

l 2.3 Two units of CM249-Q2 were supplied by Detroit Edison.:
Serial numbers 68136 and 68137.
The sequence of testing is diagrammed in Figures 1 and 2. The results of the tests are shown on data sheets and oscillograph as referenced in the test sequence figures.
Tests of the two units were interspersed, but the sequence of tests for each unit was as shown in Figure 1 and 2.
2.4 Functional testing, paragraph 3 of -QTP621, was performed I l
prior to the Fault Tests of paragraph 4.1.3 or 4.2,3 of l QTP621, and subsequent to the rework of CM249-Q2 units.
As a normal routine, the AC carrier voltage and frequency were measured and recorded at the start of the Functional l Tests, as required by QTPhil, Section 3.1. The data sheet for the first functional test is shown in Appendix A, Sh 1. The DMM (digital multi-meter) model and serial number and the counter model and serial number war recorded along with the instrumeat readings for paragraph 3.1.1 and 3.1.2 data, similarly, the test equipment identification and data readings were recorded for paragraph 3.2, 3.3 and 3.4 tests.
The data sheet results were compared to the limit criteria and the data sheet information was witnessed and signed off by Validyne Engineering and Detroit Edison personnel. All of the functional tests (Appendix A, Sh 1, 2, 4, 6, 8& 10) met the specified requirements.
2.5 The two CM249-02 test units were reworked subsequent to fault tests in which fuse components Nere caused to open.
After fuse component replacement the CM249-02 units were available for further testing without having the silicone potting material replaced in the area of the component replacements. This was an expedient procedure which was deemed to be of no consequence in effecting the subject tests. The visibly rapid interruption times of the fuses in these fault tests are not affected by the presence of silicone potting.
After completion of the testing, the two test units were re-potted and passed the formal production acceptance test procedure, ATP440. The procedure and test reports are shown in Appendixes G and H.
2.6 Detailed connection diagrams are shown in -QTP621. The connections used for paragraph 3, Functional Tests are shown in Figure 1.
The carrier voltage, connected to pins 1 and 4 of the CM249-02 output terminals, is derived from the PS171 plug-in, via jumpers in the CD173 in clot 1 of the MC170T Module Care.

measurement of the carrier voltage amplitude was done .by l l temporarily reconnecting DMM "A" across CM249-Q2 output terminals 1 to 4. The carrier frequency was measured using i the counter, connected as shown in Figure 1.
I The data sheets indicate the test equipment identifications for those instruments which were shown in the test figures as requiring calibration certifications.
a 2.7 The test connections for CM249-02 fault testing with carrier applied were as shown in Figure 2 of QTP621. In this setup as well in the fault test setup of Figure 3, a solid-state switch was used to connect the 120Vac, 60Hz. power source to the output terminals of the CM249-02.
An incandescent lamp, 100 watts, was used to insure that the solid state switch would continue ccnduction for each full half-cycle of the line voltage once initiated by the Datel DVC8500, shown in Figure 2 & 3. The lamp also served as an indicator of the presence of fault power. :
4 Prior to connecting the 120Vac to the CM249-02, the voltage amplitude across the 100 watt lamp was checked using DMM "A" verified to be within the range specified in paragraph 4, (103 to 127Vac).
A trigger circuit was constructed to trigger the oscilloscope when the first zero-crossing of the fault power was applied.
A full wave rectified signal, transformer-isolated from the power line, was applied to the channel B oscilloscope input. ,
This waveform was used to trigger a single-sweep of the storage oscilloscope and was recorded along with the signal of interest:
1 The input terminals of the CM249-02, terminated in a 10,000 !
Ohms +1% resistor, were monitored by channel A of the {
oscilloscope and by DMM "B" shown to Figures 2 & 3 of QTP621. )i Prior to making the 120Vac connections at the CM249-Q2 cutput j terminals, the fault test circuits of Figures 2 & 3 were i exercised repeatedly to insure that the oscilloscope was adjusted to reliably trigger and record the transient signal i
information. Once desired oscilloscope response was j established, the fault power was turned off and the CM249-02 i output terminals were connected as required in Figures 2 or l 3, and the fault test of 4.1 or 4.2 was conducted. l NUMBER REV QTR87-018 SHEET 8 0F 17 8626 WILBUR AVENUE.NORTHRIOGE.

- 3. TEST EQUIPMENT 3.1 Qualification Test Procedure QTP621, in Section 2, describes the equipment needs for the Maximum Credible Fault tests of the CM249-02. Many of the items are not needed to be maintained as calibrated to NBS traceable standards, since their operation in these tests is readily verified by j measurement using other certified instruments. l l
Several examples illastrate this principle:
A) Figure 1 of QTP621 shows the use of an uncalibrated DC voltage source (the Datel DVC8500 was used), the operation of which was verified by using a certified DMM "A".
B) In the same figure, DMM "A" was used to measure the carrier voltage as required in 3.1.1.
C) In Figure 2 and 3, DMM " A" was used to confirn.103 to 127Vac line voltage as required in 4.
3.2 Appendix E contains a test verification data sheet for the Tektronix Model 2230 Oscilloscope, serial number 11343.
In Part (A) of Appendix E, the vertical sensitivity of the input channel A was verified on the 20mV/ division range, which was the range used for monitoring the CM249-Q2 input circuit noise.
Part (B) of Appendix E checked the sweep calibration. The MC170 carrier frequency was verified by the (certified)
HP5315A counter to be 3,00lHz. The oscilloscope, at 0.5 mS/div read 15 cycles in 10 divisions, or 3,000Hz.
The sweep was also checked using the 120Hz waveform, d eriv t-d from Figure 2 of QTP621. The HP5315A verified the input frequency to be 120.01Hz., and the observed number cf cycles was 48 on the oscilloscope in 8 divisions at 50 msec / division. This is exactly 120.00Hz according to the oscilloscope indications. See Appendix A, Sheet 12, for an oscillograph example. The lower trace waveform is the 120Hz signal, and the oscilloscope trace range was 50 eSec/ division.
3.3 Appendix D contains the test equipment certifications for t%ose items of equipment which were identified in QTP621, Section 2.2. as requiring calibration certification.

- 4. ANALYSIS OF TESTS 4.1 Oscillosco e memory was graphically reproduced by the EPSON HI-80 X-Y Plotter. These oscillograph are shown in Appendix A, sheets 11-24.
The oscillograph use several notations to explain the waveform. An example using Appendix A, Sheet 16, is marked up and shown as Figure 3, following this page.
The A V1 indicates the voltage difference between the first and *second cursors for the V1 waveform (upper trace), A T is the time difference between the first and second cursors. The T symbol indicates the trigger point of the channel B waveform.
All the transient waveforms were 2 seconds in total length in the single-sweep oscilloscope memory. The trigger point was pre-set at 5% of the total memory, such that playback can show the results for up to 0.1 second preceeding the start of the fault application. The memory contains 1.9 seconds of waveform subsequent to the fault application. Oscillograph reproduced for this report show several views:
The full 2 seconds at 0.2 seconds / division, A 0.5 second view at the start of the fault, A 0,05 second view at the start of the fault, and for some waveforms, a 0.05 second view of some transient, later in the memory.

l 4.2 The oscilloscope was used to record the transient phenomena which occurred during a 2-second window, 95 percent of which was subsequent to the fault voltage application to the CM249- '
02 output circuitry.
The DMM "B" in QTP621 Figures 2 and 3 was observed during interval 2 through 10 seconds subsequent to fault voltage application to detect any " longer term" effects on the CM249-02 input circuit.
4.3 Visual observation of the CM249-02 circuitry during, fault testing was possible by placing the unit with the mounting surface "up" on the test bench. This orientation exposed the transparent silicone potting to the view of the observers, and allowed the functional internal circuit components to be seen through the potting.
During the fault application the observers were prepared . to note any mechanical effects of the pulse, such as smoke, heating, sparks, or other effects. The observed results were quite minor. For an instant when the fault was first applied, >
observers were able to see a small burst of light coming from ,
within the fuse (or fuses) which were caused to open due to l the fault current. No other effects were noted, such as !
sparks, smoke, heating, sounds, ete-. Upon examination the open fuses were found to be intact externally and did not exhibit visible mechanical damage. The open fuses were determined by continuity testing, using the Kiethley Model 191 DMM.
4.4 Analysis of the tests performed on the CM249-02, serial number 68137, is given in the section. Refer to Figure 1, shown in Section 2 of this report, to see the steps followed in testing this unit.
4.4 (A) Functional Test per QTP621, Section 3. This test resulted in Data Sheet page 1, shown in Appendix A, Sheet 1. j The carrier amplitude and frequency were verified to meet specifications, and the CM249-Q2 functionality was confirmed to meet the specified tolerances of 3.2, 3.3 and 3.4.
4.9 ta: Fault Test per QTP621, Section 4.2.
This test resulted in Data Sheet page 7, shown in Appendix A, Sheet 7. Oscillograph were reproduced from the oscilloscope memory and are shown in Appendix A, Sheets 17-20. The test worked successfully and created no disturbance at the CM249-Q2 input circuit of greater than 10mV, or lasting for more than 20 milli-seconds. NUMBER REV QTR87-018 i
SHEET 12 0F 17 8626 WILBUR AVENUE . NORTHRIDGE. CAUFORNI A 91324.(8181886 2057. TELEX 65-1303 VEC 305-moo

The DMM "B" registered 7.1 mV rms during the 2 to 10 second period after the fault was applied. This was within the 10mV maximum specified limit.
Examination of the oscillograph shown as Appendix A, Sheet 17, shows the 2 second total memory stored in the i oscilloscope at the start of this fault test. The lower trace j (V2, Channel B), was derived from the 120Vac, 60 hertz fault voltage, as shown in QTP621, Figure 3.
The upper trace is the waveform detected at the CM249-02 input circuit (V1, Channel A). The frequency of the Channel A waveform is seen to be 60Hz. The waveform is centered upon zero volts and peaks of typically 10mV are seen along with several spikes near 20mV peak. None of the spike pulses has a width approaching 20 milli-seconds, which is the criteria for concern in this test. The waveform signature is caused by the stray capacitance between input and output of the CM249-02.
About 16 pico-Farads of capacitance could create a 60Hz.
current of 0.69 micro-Amperes, which would cause the waveform amplitude of 6.9mV rms across the input circuit terminating resistor of 10,000 Ohms. ATP 440, in Section 5.1, limits the isolation capacitance to a maximum of 15.9 pF.
Since the stray capacitance gives the derivative of the fault power waveform, it can be understood that minor voltage surges show-up as " spikes" on the Channel A trace.
Another concept for each of the fault test oscillograph to be considered is that the fault current is interrupted by the fuse within probably 10 milli-seconds. A data sheet and time-current curve for the 1/4 - Amp rated fuse used in the CM249-02 is shown in Appendix A, Sheet 28, 29. On sheet 29, one can find the typical blow-time for a 1 Amp current, for the 1/4 -
Amp fuse is 7 msec. All of the oscillograph shown in this report are quite long in duration compared to the probable fuse-blow interval. As a result there is no stored-energy evidence in any of the waveforms to suggest anything could happen subsequent to the fault current interruptions by the fuse. This has also been verified by the stable low voltmeter reading of QTP621, paragraph 4.2.3 C.2.
Expanded views of the waveform under discussion are shown in Appendix A, Sheets 18-20. On sheets 18 and 19 the response waveform in the interval just preceeding and right after the fault application occurred is shown. Sheet 20 shows a window about 1.2 seconds after the trigger. None of these waveforms exceed the acceptable limits.

4.4 (C) REWORK The data sheet Appendix A, Sheet 7, indicated that fuse F1 ,
was found intact after the Fault Test. This was unusual, since earlier informal testing on different CM2A9-02 units had typically blown both F1 and F2 in this test setup. The two fuses, of equal rating, are in series with the fault current and had both blown open on several previous tries. It was decided to rework the S/N 68137 unit by replacing the bad F2 fuse and also the F1 fuse which still had continuity. The plan was to repeat the fault tests of QTP621, Section 4.2, to see if earlier "two open fuse" results would be obtained. The removed fuse F1 was saved for later testing. No other damage was observed during the rework of the CM249-02.
4.4 (D) Functional Test per OTP621, Section 3.
This test resulted in Data Sheet page 8, shown in Appendix A, Sheet 8. All requirement were met in this test.
4.4 (E) Fault Test per QTP621, Section 4.2.
This re-test (with F1 and F2 replaced) was recorded on Data Sheet 9 (Appendix A, Sheet 9). Oscillograph from this test ^
are shown on Appendix A, Sheets 21-24. All test criteria for acceptable results were met in this test. Both fuses F1 and F2 were determined to hase opened during this fault test and the Channel A trace was much lower in noise than resulted in l the previous test (4.4.B Above). A spike at the beginning of j the fault was observed, but the amplitude of 17mV had a 1 duration under 2 msec, well under the limit value of 20msee i permitted by the test plan. Sheet 23 of Appendix A shows this first spike most clearly. j A second spike was seen on Sheet 21, around the 95 percent i point of the 2-second long memory. the second cursor is superimposed on Sheet 21. An expanded view of this portion of the waveform is shown on Sheet 24, where it is seen to be under 2 msec duration, and about 13mV below the average baseline of Channel A waveform. No exceedance of the test plan acceptable limits was observed. i j
This re-tect resulted in both fuses F1 and F2 being open, which disconnected both sides of the fault voltage source ;
from the CM249-02 output circuit. As a result the fault i voltage was no longer impressed on the CM249-02 transformers l and the differentiated 60Hz current observed in the first test (4.4, B) was not present here. The fault test of QTP621, Section 4.2 can result in either one or two fuses being interrupted. Either result meets the acceptable requirements of the test plan.

4.4 (F) Rework The CM249-02 S/N 68137 was reworked to replace F1 and F2 subsequent to the fault test described in 4.4 (E). No damages '
beyond the two fuses was observed. ,
4.4 (G) Functional Test per QTP621, Section 3.

This test resulted in Data Sheet page 2, shown in Appendix A, Sheet 2. All requirements were met in this test, and the unit was confirmed to be ready for Fault Testing.
4.5 (B) Fault tests per QTP621, Section 4.1.
This test resulted in Data Sheet page 3, shown in Appendix A, Sheet 3. While the test produced acceptable performance results,, it was noted that the carrier voltage (See Figure 2 of QTP621) was accidentally left "off" during the fault test. It was decided to repeat this test witn the carrier voltage "on" after rework of the CM249-02. The oscillograph depicting the results of the Section 4.1 tests (but with carrier "off") are shown in Appendix A, Sheets 11-13. The Channel A (upper trace) signal met the criteria for not exceeding 10mV for a period exceeding 20msecs. The peak excursions were less than 10mV and the spike widths were far shorter than the 20 msec acceptable values. Fuse F3 was found to be open as a result of the Fault test.
4.5 (C) Rework The unit was reworked to replace F3, and no other damage was noted during the rework.
4.5 (D) Functional Test per QTP621, Section 3.
This test subsequent to the rework above, resulted in Data Sheet page 4, shown in Appendix A, Sheet 4. All requirements were met in this test, and tae unit was confirmed to be ready for a repeat of the Section 4.1 fault tests.

l 4.5 (E) Fault Tests per QTP621, Section 4.1.
Results of the re-test are found in Data Sheet page 5, Appendix A, Sheet 5. Oscillograph of the waveforms are shown in Appendix A, Sheets 14-16. Very quiet response is seen for Channel A (upper trace) on each of these sheets. The test resulted in fuse F3 being open, as before, and all acceptable requirements for Section 4.1 were met in this test.
4.5 (F) Rework The unit was reworked to replace F3, and no other damage was noted during the rework.
4.5 (G) Functional Test per OTP621, Section 3.
Data Sheet page 6, Appendix A, sheet 6 shows the results of this test. All requirements were met in this test, confirming that normal operation was restored after replacement of the fuse F3.
- 5. SUBSEQUENT TESTS The fuse, F1 from the rework described in 4.4 (C) above, was tested to see if it was unusual compared to other fuses of the same type. These tests were performed by Validyne '
personnel on July 23, 1987. Data sheets for the tests on two new fuses (same rating and port number as the f use F1) are shown in Appendix A, sheets 25 and 26. The same test performed on the fuse F1, removed f rom the S/N 68137 CM249-02 in the rework described in 4.4 (C) above, is shown in Appendix A, sheet 27.
The F1 fuse was shown to withstand 0.4 Amps for 10 seconds, but blew open in less than one second with 0.45 Amps applied.
The two new fuses (Appendix A, sheets 25, 26) blew open in less than 2 seconds at a test current of 0.4 Amps. Data sheets for the 1/4 - Amp fuse and the time - current !
characteristics are shown in Appendix A, sheets 28 and 29. j l
All three tested fuses blew at close to the 0.43 Amp nominal i value suggested on Sheet 29. Lot to lot tolerance variations could easily explain the 0.4 to 0.45 Amp blow-out current !
differences. Fuse F1 was not sufficiently different from others of the same type to cause any concern f or the mode of results observed in Section 4.4 (C) above.

- 6. CONCLUSIONS l
This Maximum Credible Fault Qualification Test of the CM249-Q2 has demonstrated that a 120Vac, 60Hz, 20 Amp fault applied to the output of the CM249-Q2 does not cause degradation of the isolator input signal beyond an acceptable level. The tests have shown that a fault orginating in the non-class 1E output of the isolator does not affect the integrity of the safety-related input signal.
These faults have resulted in the protective fuses of the CM249-Q2 output circuits going to their open circuit condition. This has blocked the fault currents and has prevented any other damage to the components and structure of the CM249-02. Factory -level rework can restore normal operation of CM249-02 units which have been damaged by fault currents on the output circuits.

Subject:
Maximum Credible Fault Test of CH249-Q2 Gentlemen:
Attached to this letter is our proposed Test Plan for Validyne to perform a Maximus Credible Fault Test on the CM249-Q2 Remote Carrier Modulator. This is the plan upon which we agreed in our recent telephone conversation. The test will accomplish the objective of demonstrating that this unit is capable of preventing unacceptable degradation of an input signal when a 120 vac, 20 amp fault is imposed j at its output. We would expect that any significant deviation from i the plan would be discussed with us and an evaluation of that i deviation be included in your final test report. The requirements of ]
10CFR50, App. B as.it applies to tests of this type are naturally j invoked since this involves a component qualified by you for nuclear I safety-related service. For purposes of identification. this plan is )
identified as the attachment to this letter NE-87-OO61, 1 J
We are supplying you under separate cover two test samples, drawn from j our spare parts. {

. Test Plan for Maximus Crediblo Fnuit Test Applied to Validyne Carrier Modulater CM-249-Q2 1.0 Introduction' 1EEE 279 Section 4 7.2 requires evaluation of the effects on the associated protection system of applying a mariaua credible fault to the output of a protection system isolator. The test described herein is designed to show that when a 120 vac, 60 Hz fault potential with 20 amp capacity.is applied to the output of the Validyne isolator, the input signal is not' degraded below an acceptable level. This will then demonstrate the ability of the device to isolate a fault originating in the non-class IE output from the safety-related signal input.
2.0 Fermi 2 Application The IE signals applied to the Validyne Isolators used in the ERIS system at Fermi 2 are typically either from current or voltage sources. Current sources are generally 0-1aa, 4-20aa, or 10-50 na, with the signal tapped as the voltage developed across a 1000 oha, or smaller resistor. The nazimum voltage signals are typically less than 10 yde, and are. tapped either directly or from high impedance voltage dividers. The size of the signal dropping resistor or voltage divider is determined by the anzimus permissible input voltage to the isolator, which is 5 vde, and the load impedance requirement on.the signal
. driver. Typically for a current source the load impedance is required to be less than 1000 ohns, and for a voltage source, greater than 1500-
'ohns. ,
s The smallest signal range tapped by the ERIS systen applied to a Talidyne CM-249-Q2 isolator is 0 to 1.0 yde, while typical input voltage spans je 2.0 yde and 4.0 ydc. While many of the ERIS signals are derived i g a dedicated, bufferred outputs that could withstand the imposition oTyany volts of transient without affecting the IE signal, some are det 94 from direct parallel or series connections with the IE signal. A ietlure of the Validyne isolator to block the energy from a maximum crediole fault driven from the non-IE side of the isolator could result in fault volt-amperes being combined with the IE signal.
For instancs, if a non-IE fault resulted in an additional voltage of 10nv being added to the IE signal voltage whose span is 1 volt, an error in IE sign &1
- 1 percent of span would be produced. Typical IE signal error allow is are auch greater than 1 percent of span. The allowance for the 1 : tor water level wide range signal accuracy, fc,r example, is 1 5% of span. 1 30 criteria When 120 vac, 60 Hz from a 20 aspere source is applied to the Validyne CM-249-Q2 output terminals, no disturbance larger than 10 av steady-state shall be asasured at the input terminals. Voltage transients larger than 10 av any appear at the input provided that they persist for no longer than 20 as.

[ P;ge12 j l
1' f
Th2 basis 'for this crit:ris is that' 10 cv r::preacnts 1 % of tha .
smallest signal span utilized, and an additional 15 error in the IE signal can generally be tolerated indefinitely.. The transient duration time of 20 as is chosen based on the minimum operating time specified for one of the most prevalent:IE relays in use at Fermi 2, the Agastat
, type EGP. In order to facilitate sensurement.of the fault volt-asperes at the. isolators, the_ input shall be terminated with 10 kohns
- resistance. ,
4.0. Procedure l 4.1 Pre-Test Functional T2st The following test is extracted from the Instruction annual for the Validyne CM-249-Q2. See Figure 1.
4.1.1 Connect the 5 Vras 3 kHz carrier source to OUTPUT terminals l- 1 and 4, and the DVM (or scope) to OUTPUT terminals 2 and l
3 Short INPUT terminals 2 and 3 together. The DVM output l reading should be less than 10 nV ras.
l' 4.1.2 -Remove the input short and apply 5 00 301 VDC across INPUT terminals 2 and 3 'the DVM output reading should be 175 150 av ras.
4.1 3 Reverse the DC input polarity. The DVM should read 175 150 mV ras, and this reading should-be within 12% of the reading obtained in 4.1.2.
4.2 ,Marisus Credible Fault Test 4.2.1 See Figure 2. While monitoring the isolator input with a q high-speed oscillograph capable of 1 av vertical and 1 as horizonal resolution at 35 accuracy, apply 120 vac between output terminals 2 and 3. Isolator excitation is provided by a 3 kHz, 5 Vras carrier applied to output terminals 1-and 4 during the test. Fault asperage shall be limited to j 20 amperes. Test equipment shall be protected from fault energy appropriately. Maintain the application of fault long enough to establish short ters and long tera effects on the isolator.
4.2.2 Utilizing a new test sample or the sample from 4.2.1, subjected to 4 3, and then restored to pass the pre-test functional, perform the test illustrated in Figure 3 While monitoring the input as in 4.2.1, apply the 120 VAC, 20 amp source between output terminals 1 and 4. Maintain the fault application long enough to determine long ters effects.

4.3 3 Provide a description of any physical damage.

SECTION 111 MAINTENANCE & REPAIR L
3-1. MAINTENANCE.
The CM249 is a potted unit intended for unattended remote operation and contains no adjustments. If a periodic maintenance schedule is in ;
effect, the CM249 operability can be checked as part of the system by using the procedures given in the examples of Section 2. If the CM249 is to be tested as a component, the following procedures can be used.
For this, the following test equipment is required:
A. A sine-wave generator for 5 Vrms 3 kHz excitation,15 mA )
capability.
B. An AC digital voltmeter calibrated for 3 kHz input.
C. A 1000 volt megohmeter capable of reading 10,000 Megehms !
insulation resistance.
D. A DC digital voltmeter.
E. A DC signal source.
3-2. INPUT /0UTPUT TRANSFER. j j
A. Connect the 5 Vms 3 kHz carrier source to OUTPUT teminals 91 and 82, and the DVM (or scope) to OUTPUT teminals SIG and RTN. Short INPUT teminals +1N and -!N together. The DVM output reading should be less than 10 mV rms.
B. Remove the input short and apply 5.00 20.1 Vdc across INPUT teminals +1N and -!N. The DVM output reading should be 175 :50 mV ms. ,
C. Reverse the DC input polarity. The DVM should read 175 250 mV ms, and this reading should be within 22% of the read-ing obtained in Step B.

put of the CM249 will be 7 mV/V for full scale input. The de-desired output from the CD173 is 0-10 Vdc full scale.
s Step 1 - With zero pressure input (or 0.20 Vdc input to CK249),
adjust the CD173 Zero entrol for 0 Vdc output. t-Step 2 - With full scale pressure input (or 1.00 Vdc input to CM249), adjust the Gain Switch and Span control on the CD173 for +10 Vdc output. This should occur at a Gain switch setting of 5 mV/V and the Span control about 70% of full scale.
2-11. Switch Position Sensina. For switch position sensing, connect the CM249 inputs as shown in Ffgure 2-1 or 2-2. With the switch in the low-level (zero) output position, adjust the carrier demodulator Zero control for zero output. With the switch in the high-level output
' position, adjust the carrier demodulator Span or Gain control for the dekired output. ,
2-12. EXAMPLE The CM249 is te be used for sensing the closing of a remote switch, and is connected to a CD173 Carrier Demodulator in an MC370 installation. A +5 Vdc output level is to indicate switch closed, and zero output for switch open. The CM249 input is connected per Figure 2-2. (CM249 output with switch closed will be approximately 14 mV/V.)
Step 1 - With the switen open, adjust the CD173 Zero control for zero output.
Stec. 2 - With the switch closed, adjust the CD173 Gain switch and Span control for +5 Vdc output. This should occur at a Gain switch setting of 25 mV/V and a Span control' set-ting about 907, of full scale.

Cable Shieldino. In order to preserve the integrity of the iso-lation capability of the CM249, use of shielded cable for signal input connections is not reconnended. Instead, the CM249 should be mounted as close as is practicable to the signal source. The interconnecting cable to the carrier demodulator, on the other hand, should be shielded, with the shield tied to chassis ground at the carrier demodulator end.
Whenever possible, the carrier excitation leads should be in a separate shielded pair from the signal lead to minimi a capacitive unbalance be-tween the s'gnal and carrier lends.
2-9. CALIBRATION & OPERATION. f Fer setup and operation, perfom the following procedures: j I
A. Connect the CM249 to its carrier demodulator, If the carrier j demodulator has a 2-Arm /4-Arm input mode switch, set in the 2-Arm posi-tion for 3-wire cable configuration, or 4-Arm for 4-wire.
With zero signal input to the CM249 adjust the carrier de-B.
modulator for zero output.
C. Apply full scale signal input to the CM249 and adjust the carrier demodulator GAIN or SPAN control to produce the desired full scale output voltage.
2-10. EXAMPLE.
The CM249 is connected to a Validyne CD173 Carrier Demodulator in an MC170 or MC370 system fatallation. Input to the CM249 is the DC voltage across a 50 ohm resistor in a 2-wire 4-20 mA pressure transmitter loop, resulting in 0.2 Vdc input at zero pressure and 1.0 Vdc input at full scale pressure.

2-4 Voltage signal inputs are connected to the (+) and (-) INPUT '
teminal s . For a floating differential input, no signal ground con-nection is required. For a single-ended input, the signal return is connected to the (-) INPUT terminal . The BIAS terminal is not used.
l 2-5. The CM249 can be used for sensing either switch closing or f switch opening. Figure 2-1 shows the applicable input and output con-nections for switch opening mode, and Figura 2-2 wiring for switch closure mode.
2-6. The cable connef:tions from the carrier demodulator are made to the OUTPUT terminals. The carrier excitation leads are connected to the B1 and 82 terminals. Under normal conditions, only one output sig-nal lead is required, which is connected to the SIG terminal, presenting an equivalent 2-Am, or half-bridge configuration to the carrier de-modulator (the RTN, or signal return, teminal is not used).

1-6. FUNCTIONAL DESCRIPTION.
(See Figure 1-2 for a functional block diagram of the CM249) 1-7. The input signal is fed to the modulator stage through a buffer amplifier with a high input impedance. In the modulator stage, the !
signal voltage is used to modulate the amplitude of an AC carrier (nor-mally 3 kHz), which comes thru the interconnecting cable from the carrier demodulator. The modulated carrier signal is fed through a low pass filter to become the input signal' to the carrier demodulator. At zero signal input to the CM249, the output is zero. At *5V input signal, ,
the CM249 output is nominally 35 mil 11 volts per volt of carrier (mV/V) 3 with 180 output phase reversal between + and - inputs. The output -
stage contains a 4 kHz low-pass filter to eliminate carrier hannonics from the sine wave output.
1-8. A DC BIAS terminal on the input side allows sensing of the open .
or closed position of an external SPST switch (such as a valve limit switch) by biasing one or both inputs.
1-9. The eDC operating voltage for the CM249 is obtained by rectifying the carrier excitation voltage. The high electrical input / output isola-tion is provided by transfonner coupling of both the carrier excitation and output voltages.
1-10. TECHNICAL CHARACTERISTICS.
Table 1-1 lists the Technical Characteristics for the CM249.

SECTION I DESCRIPTION 1-1. INTRODUCTION.
This manual contains the installation and operating instructions for the Model CM249 Acmote Carrier Modulator manufactured by Validyne Engineering Corporation, Northridge, California.
1-2. PURPOSE & USE.
The CM249 Carrier Modulator converts a DC or low frequency AC input signal to an amplitude-modulated carrier signal for input te a carrier demodulator. It is designed for remote location at the signal source and derives its operating power from the carrier excitation supply of the carrier demodulator. It features 2000-volt input / output isolation to protect the signal conditioning system from damage and its low out-put impedance allows operation with long signal cables.
1-3. It is used in applications where DC or low frequency AC signal voltages up to :5V are to be transmitted with good protection from high common-mode input voltage or transient high voltage inputs. It can also
- , be used to provide a high/ low output level to indicate an open or closed position of a remote switch.
1-4 Although designed for use with any of the Validyne carrier demodu-lators, it is compatible with other carrier demodulators providing 4-6 Vac 3 kHz balanced sine wave excitation.
', 1-5. PHYSICAL DESCRIPTION.
i Figure 1-1 shows the physical configuration of the CM149, and the CM249 Outling Drawing in the Appendix shows the mounting dimensions. The electronic circuitry is completely potted in a thermoplastic case. In-put and output connections are made via barrier-type screw terminals.
