Conditions for
Testing Off
Line
The following steps verify that the rectifier responds properly to plant
controller commands and outputs proper signals in return. Referring to
Schematic Drawing SD83102-03 may be helpful while performing
these procedures.
1. Verify that the ac supply and rectifier controls are as shown in
Table 6-B.
2. Use the documentation for the particular battery plant to perform
all the preliminary checks on the plant prior to the rectifier tests. If
the rectifier is in a microprocessor- controlled plant with an
efficiency algorithm feature, disable this feature. (See the
appropriate controller manual for instructions.)
3. Using the digital multimeter (DMM) on the dc volts scale, make
the following checks:
a. Verify that dc voltage is not present between the rectifier output
bus bars. See Figure 5-3.
b. Install the regulation (REG) fuse associated with the rectifier in
the plant controller.
