5-27Controller Cards
Original — December 1991 UM4.6:CS6003
5.8.2 Calibration Procedure
Use the following procedure to calibrate the card:
Step 1: Verify that the calibrator ON/OFF switch is OFF.
Step 2: Insert the indicator card shown in Figure 5-14, in the test slot
labeled CONFIG SVCE XFER IND.
Step 3: Set the calibrator ON/OFF switch to ON.
Step 4: Connect the voltmeter between test point TP1 on the indicator
card and the –CO1 breakout terminal on the calibrator.
Step 5: Ensure the INT/EXT switch is set to INT.
Step 6: Press the CAL LOW switch. The voltmeter should read 0.995
± 0.003 volts dc. If not, adjust the ZERO (R18) potentiometer
on the indicator card to obtain the proper reading.
Step 7: Press the CAL HIGH switch. The voltmeter should read 4.975
± 0.003 volts dc. If not, adjust the SPAN (R13) potentiometer
on the indicator card to obtain the proper reading.
Step 8: Because the ZERO and SPAN adjustments interact, repeat
Steps 6 and 7 until the proper readings are obtained without
an adjustment on any step.
Step 9: Disconnect the voltmeter.
Step 10: Set the calibrator ON/OFF switch to OFF.
Step 11: Remove the indicator card.
5.9 Type CP7202 Controller Power
Conversion Card
This calibration procedure for the controller power conversion card
allows the user to adjust the output voltage levels and the alarm trip
points. Adjustments are made by observing the voltmeter and the
RESET TEST and RELAY TEST indicators on the calibrator, and then
adjusting potentiometers on the power conversion card.
