6 - 4 Testing
Issue 6 October 1998
Initial
Conditions for
Testing Off
Line
The following steps establish initial conditions for the
equipment before testing.
1. Verify that the ac supply and rectifier controls are as
shown in Table 6-A.
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 controller manual for
instructions.)
3. Using the digital multimeter (DMM) on the dc volts scale,
make the following checks:
–
Before the REG fuse is installed in the plant controller,
verify that battery voltage is not present between the
rectifier output charge terminal and dc output return (see
Figure 5-4).
–
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 J2A. The J2A connector is at
the rectifier end of the plant control cable. Pin 27 should
be positive with respect to pin 2.
