Step 4: Press the calibrator RESET switch. The IN PROGRESS
indicator lights and remains lit until the card self-test is
finished. When finished, the COMPLETE indicator lights. If
the COMPLETE indicator fails to light within one minute, the
MPU and discrete I/O cards require repair.
Step 5: Press the CAL LOW switch.
Note
The SCAN ERROR indicator may be lit while the
calibrator is in the CAL LOW mode. This is a
normal condition.
Step 6: Observe the CONTROLLER DO indicators. CONTROLLER
DO indicators 1 thru 4 light up sequentially and then repeat
the sequence. If a discrete I/O card is also being tested,
CONTROLLER DO indicators 5 thru 8 are also part of the
sequence. If some or all of the CONTROLLER DO indicators
fail to light or light in an incorrect sequence, the MPU card or
discrete I/O card requires repair.
Step 7: Press the CAL HIGH switch.
Note
The SCAN ERROR indicator may be lit while the
calibrator is in the CAL HIGH mode. This is a
normal condition.
Step 8: Observe the CONTROLLER DO indicators. CONTROLLER
DO indicators 1 thru 4 blink on and off as the discrete outputs
are subjected to a binary counting test. If a discrete I/O card
is also being tested, CONTROLLER DO indicators 5 thru 8
are included in the binary counting test. If some or all of the
CONTROLLER DO indicators fail to light, the card or cards
require repair.
Step 9: Ensure that all switches labeled MUX DI/DO OR
CONTROLLER DI are OFF.
Step 10: Press the SCAN switch. The NONE ACTIVE indicator of the
DI STATUS indicators lights. If the NONE ACTIVE indicator
fails to light, or if another of the DI STATUS indicators lights,
the MPU card or the discrete I/O card requires repair.
