5-15Controller Cards
Original — December 1991 UM4.6:CS6003
Step 8: If the configurable controller card does not have discrete I/O,
skip to Step 9. Otherwise, observe that CONTROLLER DO
indicators 1 thru 7 light up in sequence and then repeat the
cycle. If the CONTROLLER DO indicators fail to light, or light
in an improper sequence, the configurable controller card
requires repair.
Step 9: Press the CAL HIGH mode switch. The OK indicator of the
CAL STATUS indicators should light. If not, adjust the SPAN
(R22) potentiometer on the configurable controller card to the
mid range of settings over which the OK indicator lights.
Step 10: If the configurable controller card does not have discrete I/O,
skip to Step 11. Otherwise observe that CONTROLLER DO
indicators 1 thru 7 blink on and off in a binary counting test. If
some or all of the seven CONTROLLER DO indicators do not
blink on and off, the configurable controller requires repair.
Step 11: Repeat Steps 7 thru 10 until the proper indications occur
without adjustment on any step.
Step 12: Connect jumpers from the +CO1 and –CO1 breakout
terminals to the 250 ohm LOAD terminals.
Step 13: Connect the voltmeter across the 250 ohm LOAD terminals
(ensure the calibrator is in the CAL HIGH mode). The
voltmeter should read 5.00
± 0.01 volts dc. If not, adjust the
configurable controller card Current Output SPAN (R17)
potentiometer to produce the proper reading.
Step 14: Press the CAL LOW mode switch and observe the voltmeter.
The voltmeter should read 1.00
± 0.02 volts dc. If not, the
configurable controller requires repair.
Step 15: Press the SCAN mode switch. The OK indicator of the CAL
STATUS indicators should light. If the SCAN ERROR indicator
of the CAL STATUS indicators lights, repeat Steps 7 thru 11
and then repeat this step.
Step 16: If the configurable controller card does not have discrete I/O,
skip to Step 20. Otherwise, press Switch 1 of the data
switches labeled MUX DI/DO OR CONTROLLER DI. The 1
ACTIVE indicator of the DI STATUS indicators should light. If
the 1 ACTIVE indicator fails to light or if another indicator
lights, the configurable controller card requires repair.
Step 17: Press Switch 2 of the data switches labeled MUX DI/DO OR
CONTROLLER DI. The 1 ACTIVE indicator goes out and the
> 1 ACTIVE indicator should light. If the > 1 ACTIVE indicator
fails to light or if another indicator lights, the configurable
controller requires repair.
