2000 400A, 60Hz Ferroresonant Rectifier J85503C-3
6 - 8 Testing
Issue 10 July 2000
Testing Off
Line
The following tests involve use of the test load and a Battery Plant
Simulator Test Set. Refer to “Tools and Test Equipment” for the
procedures to construct a Battery Plant Simulator Test Set and to
connect a test load.
Refer to Figure 2-2 for location of circuit boards used in the following
tests.
If the rectifier fails any of the tests in this section, replace the CM2
board and begin testing again.
Startup
1. Turn on the ac supply to the rectifier. The PWR lamp on the test
set should light brightly. If it does not light properly, check the
connection of the two small red and black clip leads. They may be
reversed or otherwise incorrectly connected. These leads provide
the operating voltages in the test set, and the red lead should be
approxi27 volts dc with respect to the black lead.
2. The PWR lamp should remain lit during the remaining tests as
long as the ac supply is turned on.
3. Set the test meter to the 100 volts range, and connect it to the Rect
jacks on the rectifier control panel. (See Figure 2-2.)
4. Adjust the test load so that when the rectifier is turned on, it will
deliver 20-80A, 5 to 20 percent of full load.
5. Place the S1 switch on CM4 in the LOC position (see Figure 5-6),
and turn the Power switch On. The rectifier should start and the
green Power LED on the front panel should light. The test meter
should indicate 40-50 volts. The MAN lamp on the test set should
light and remain lit as long as the rectifier is turned on.
Regulation (NL/
FL) Test
1. Watch the test meter and move the Rect Test switch to NL. In the
NL position, the voltage should drop between 0.3 and 0.6 volt.
2. Repeat Step 1 with the Rect Test switch in the FL position. The
voltage should increase between 0.1 and 0.4 volt.
