2000 25A Ferroresonant Rectifier J85502A-1
Issue 4 May 1998
Testing 6 - 11
5. Restart the rectifier using the RS switch on the test set.
6. 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
LED 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.
3. Press the HV switch on the test set. The rectifier should
continue to operate.
Selective High
Voltage
Shutdown
(SHVSD) and
Restart
1. Adjust the test load so that the rectifier delivers 2.5-4A, 10
to 15 percent of its rated amperage.
2. Momentarily press the HV switch on the test set. The
rectifier should shut down and the RFA lamps on the
rectifier and the test set should light.
3. Momentarily press the RS switch on the test set. The
rectifier should restart and both RFA lamps should go off.
Meter
Calibration Test
(Off Line)
1. Connect the test meter between the positions 1 and 2 on
TB3 (see Figure 5-2).
2. On the rectifier, hold the meter selector switch in the
RECT V position. The digital display should agree with
the test meter within 0.02 volt for Series 3 CM3 boards or
within 0.5 volt for Series 1 or 2 CM3 boards.
3. Hold the meter selector switch in the BATT V position.
The digital display should agree with the test meter within
0.01 volt. If the display and test meter do not agree, the
207A digital meter board needs adjustment (see “Calibrate
CM3 Digital Meter” in Section 7).
