Battery Plant
Simulator Test
Set
The Battery Plant Simulator Test Set is a convenient tool used to
isolate communication troubles between the plant controller and
the rectifier. It simulates the plant controller relative to receiving
signals from, and sending signals to, the rectifier. If there is a
problem and the rectifier works properly with the test set, the
problem is either at the controller or in the interface wiring (plant
cable). Figure 6-1 shows how to construct a test set and cable.
Test Load
Connection
The following procedures are used to connect a test load when
called for in a test or other procedure. Refer to the rectifier
control panel in Figure 2-1. Test load connections are made on
the output terminal block of the rectifier, after the DC OUTPUT
circuit breaker. Therefore, the rectifier must be disconnected
from the plant charge and charge ground bus bars in order to
isolate the unit from the batteries.
1. Turn the rectifier POWER switch Off.
2. Turn Off (down) the rectifier DC OUTPUT circuit
breaker.
3. At the ac service panel, remove ac power to the rectifier.
4. Disconnect the rectifier's “hot” output lead from the plant
charge bus bar. Tape the loose connector.
5. Disconnect the rectifier’s ground output lead from the
charge ground bus bar. Tape the loose connector.
6. Disconnect the + and - output leads from the left side of
TB3, the rectifier ends of cables disconnected in Steps 3
and 4. Tape loose connectors.
Caution
•
Support the CM2 control board when disconnecting the
cable leads or damage to the control board may result.
•
Do NOT disconnect plant control cable connector J2A
from control board CM2 by pulling the cable.
