2000 100A Ferroresonant Rectifier J85503A-1
Issue 6 October 1998
Testing 6 - 9
3. Verify that no ac voltage is present on the input leads of
the ac contactor K1 (see Figure 5-3).
4. Disconnect one input lead, L1, L2, or L3 on K1, or at the
ac service panel, whichever is more convenient. Insulate
the lead.
5. Turn on the ac at the service panel. The rectifier should not
restart, and the PWR, MAN, and PH lamps on the test set
should light. The PHA lamp on the rectifier should also
light.
6. Turn off the ac at the service panel and reconnect the input
lead.
7. Turn on the ac at the service panel. The rectifier should
restart. On the test set, only the PWR and MAN lamps
should light.
Backup High
Voltage
Shutdown
(HVSD) Test
(Off Line)
1. If the DC Output circuit breaker is On, turn it Off (down).
2. Slowly turn the Output Volts Adj potentiometer
clockwise until the rectifier shuts down. This should occur
between 29 and 31.25 volts (24-volt rectifier) or between
58 and 62.5 volts (48-volt rectifier). The RFA on the
rectifier and the RFA on the test set should light.
3. Turn the Output Volts Adj potentiometer
counterclockwise.
4. Restart the rectifier using the RS switch on the test set.
5. Adjust the voltage to approximately 26.0 volts (24-volt
rectifier) or 52.0 volts (48-volt rectifier). The RFA lamps
on the rectifier and the test set should go out.
Control (TR) Test
1. Press and hold the transfer rectifier (TR) switch on the test
set for 5 seconds. The rectifier should turn off simulating a
remote shutdown from the controller. The Power On light
should go off. The digital meter on the rectifier should go
off, and the TRH lamp on the test set should light.
2. Release the switch. The rectifier should restart and the
TRH lamp should go out.
