5-20 Controller Cards
UM4.6:CS6003 Original — December 1991
Step 5: Ensure the INT/EXT switch is set to INT.
Step 6: Connect jumpers from the +CO1 and –CO1 breakout
terminals to the 250 ohm LOAD terminals.
Step 7: Connect the voltmeter across the 250 ohm LOAD terminals.
Step 8: Press the CAL LOW mode switch. The OK indicator of the
CAL STATUS indicators should light. If not, adjust the ZERO
(R44) potentiometer on the computing controller card to the
mid range of settings over which the OK indicator lights.
Step 9: Observe the CONTROLLER DO indicators. CONTROLLER
DO indicators 1 and 2 light up in sequence and then repeat
the cycle. If the CONTROLLER DO indicators fail to light or
light in the wrong sequence, the computing controller card
requires repair.
Step 10: Press the CAL HIGH mode switch. The OK indicator of the
CAL STATUS indicators should light. If not, adjust the SPAN
(R45) potentiometer on the computing controller card to the
mid range of settings over which the OK indicator lights.
Step 11: Observe the CONTROLLER DO indicators. CONTROLLER
DO indicators 1 and 2 blink on and off in a binary counting
test. If CONTROLLER DO indicators 1 and 2 fail to blink on
and off, the computing controller requires repair.
Step 12: Repeat Steps 8 thru 11 until the proper readings occur
without adjustments on any step.
Step 13: Observe the voltmeter (ensure the calibrator is still in the CAL
HIGH mode). The voltmeter should read 5.00
± 0.01 volts dc.
If not, adjust the computing controller card Current Output 1
(CO1) SPAN (R61) potentiometer to obtain 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
computing 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 8 and 11
and then repeat this step.
Step 16: 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 of the DI STATUS indicators lights, the
computing controller card requires repair.
