Line
The following steps verify that the rectifier responds properly to
plant controller commands and outputs proper signals in return.
Referring to Schematic Drawing SD83281-01 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:
• Verify that dc voltage is not present between the
rectifier output bus bars. See Figure 5-3.
• Install the regulation (REG) fuse associated with the
rectifier in the plant controller.
• Check for battery voltage between pins 27 and 2 of
control cable connector J5A. The J5A connector is at
the rectifier end of the plant control cable. Pin 27 should
be positive with respect to pin 2.
• As an extra precaution, check for battery voltage
between ground and pin 2 (-48V or -24V rectifier) or
pin 27 (+24V rectifier). If no voltage exists, there is a
wiring problem associated with the control cable or
controller. The problem must be found and repaired
before proceeding with testing.
