1 Turn OFF the ac circuit breaker of rectifier #1. Verify that
the AC and MIN alarm LEDs illuminate, the rectifier

FAIL : G01.
2 Turn ON the ac circuit breaker of rectifier #1. Verify that the
rectifier starts and the alarms retire.
3 Turn converter #1 (if equipped) from ON to STBY. Verify
that the REC-MIN alarm LEDs illuminate and the controller
alarms screen indicates CONVERTER FAILURE : C01

4 Turn converter #1 ON and verify that the converter starts
and the alarm retires.
5 Simulate a load circuit breaker alarm by shorting the alarm
contacts on the circuit breakers or inserting an operated
alarm fuse. For ED83143-31 G1-6 (101-106), add a jumper
from the hot bus to the FAJ input signal on the associated
BNL1 (P4-1) or BNL7 (P5-6) alarm card. Verify that the
DIST and MAJ alarm LEDs illuminate and the controller
alarms screen indicates EXTERNAL FUSE MAJOR.
