2000 125A Ferroresonant Rectifier J85502C-1
6 - 14 Testing
Issue 8 July 1999
equalize voltage you just established. If not, use the
EQUAL ADJ potentiometer to correct the voltage.
7. Turn the POWER switch Off.
8. Remove strap on test points E16 and E17.
9. Turn the POWER switch On. The EQUALIZE LED
should be off and voltage should be at float.
Test for 434A or
434B Circuit
Module
1. Turn the rectifier On/Off switch to On. Adjust the load
about 20-30% of rectifier rated current capacity. The green
LED should be on.
2. Using the clip lead, momentarily short E1 and E14 (+12V).
The rectifier should shut down, and the red RFA LED
should be on.
3. Restart the rectifier by cycling the front On/Off switch.
4. Using a clip lead, momentarily short E3 and E14 (-12V).
The rectifier should shut down, and the red RFA LED
should be on.
5. Restart the rectifier by cycling the front On/Off switch.
Off-Line Test
Completion
1. Reduce load so the rectifier delivers 25-38A, 20-30% of its
rated current.
2. Adjust the OUTPUT VOLTS ADJ potentiometer to
between 52.02 and 52.13 (or 26.01 and 26.06) volts read
on the OUTPUT meter, or to float voltage as determined
in “Adjusting Rectifiers to Float Voltage” in this section.
3. Turn the POWER switch Off.
4. Reduce the load to zero.
5. Turn Off the ac power at the ac service panel.
6. Disconnect and remove the Battery Plant Simulator Test
Set, the DMM (Digital Multimeter), and the test load.
