Lucent Technologies 415B Battery Plant for 4ESS
Issue 6 September 1999
System Testing 5 - 9
Perform the following procedures before continuing test:
•
Turn all rectifiers to the Off position via the ON/OFF power
switch at the rectifier.
•
Remove all control (J202) and REG (J208) cables at the
208G board in all rectifiers.
•
Turn all battery switches to the Off position at the Control
and Distribution Bay.
FA Test
1. Replace a fuse on the 329B (CM1) board with a blown
fuse. Turn on the rectifier via the ON/OFF power switch.
The rectifier shuts down immediately and the RFA and FA
LEDs should light on front of the rectifier.
2. Turn off the rectifier via the ON/OFF power switch.
3. Repeat Steps 1 and 2 until all five fuse positions on the
329B have been tested and verified.
4. Turn off the rectifier via the ON/OFF power switch.
Replace the blown fuse with a good fuse.
BUHVSD
5. Set load to 10-20 amperes.
6. Turn on the rectifier via the ON/OFF power switch, and
record the voltage on the display. This recorded voltage
will be used to reset the rectifier in Step 11.
7. Set the load to 2 amperes and adjust to 161.5 volts.
Observe that the rectifier remains operational.
8. Increase the voltage by depressing the RAISE VOLTAGE
pushbutton to 164.5 volts. Within 20 seconds the rectifier
will shut down and the red RFA led will light.
9. Turn off the rectifier and lower the voltage via the
LOWER VOLTAGE pushbutton by depressing the switch
for approximately five seconds.
ISHVSD
10. Set load to 15 amperes (minimum) and adjust the output
voltage to 158.5. (Wait 30 seconds). The rectifier should
not shut down. Increase the voltage to 161.5 volts. Within
