2000 MCS controllers and when the
output current reading on the rectifier does not agree to within
±2.5 percent of the rectifier output current reading on the
controller. This procedure must be performed while connected
to the controller and a battery.
Refer to Figure 6-3 for components on the 208F1 control board.
Plant control cable connector J5A MUST be connected to P5A
on CM4 for this procedure.
1. Connect a DMM, set on the dc millivolt scale, across the
329 test points E25/E26. See Figure 6-2.
2. Adjust the rectifier to deliver approximately 100A, 50% of
its rated current capacity.
3. Observe the DMM and record the rectifier's shunt voltage.
The shunt is rated
250A/50mV = 5A/mV
which means that each millivolt of voltage drop across the
shunt indicates 5A of output current.
4. Convert the DMM shunt voltage reading to amperes. For
example, if the DMM reads 40mV, then
40mV X 5A/mV = 200A
of output current. As this calculation indicates, the rectifier
is operating at full load, and the rectifier shunt voltage is
40mV at full load.
5. Compare the amperes calculated in Step 4 with the rectifier
drain indication on the controller.
6. If the rectifier drain indication is between 0 and 2% higher
than the amperes calculated in Step 4, and indicated on the
controller, this procedure is completed.
7. If the rectifier drain indication is not as indicated in Step 6,
adjust potentiometer R35 on CM2 control board to obtain
a rectifier drain reading on the controller that is between 0
and 2% higher than the amperes calculated in Step 4.
