4 - 6 Installation and Setup
Issue 3 August 1998
not known and is not directly indicated in the plant manual,
check the plant assembly drawing. (See Figure 4-3 or the label
on the cover plate of the 113B control unit.)
Battery on
Discharge
Threshold
The voltage threshold for the BD alarms is set with DIP switch
SW103. (See Figure 4-2.) Refer to the label on the CP1 cover
plate for the DIP switch setting for the desired alarm threshold.
The same table of settings also appears on the schematic drawing
SD-82669-02 and assembly drawing J85501D-2. The
recommended threshold is approximately 1.0 volts below the
float voltage for nominal 48-volt plants or approximately 0.5
volts below float for nominal 24-volt plants.
Be sure to also set DIP switch 6 of SW103 for the proper
operating voltage.
High Voltage
Shutdown
Thresholds
The controller is equipped with two separate high voltage
shutdown thresholds. The first is used during normal float
operation. The second threshold is used when the plant is in
equalize mode. The float shutdown is set with DIP switch
SW102 on CP1. (See Figure 4-2.) The equalize shutdown is
controlled by settings on DIP switch SW101 on CP1. The
equalize shutdown level does not need to be set if equalize is
hardware disabled (“Equalize Enable/Disable”). The
recommended shutdown levels are approximately 1.0 volts
above operating voltage for nominal 48-volt plants or
approximately 0.5 volts above operating voltage for nominal
24-volt plants. The actual operating voltages in float and
equalize modes are determined by the battery manufacturer’s
recommendations and by any restrictions imposed by the load
equipment.
DIP switch position 6 on SW101, SW102, and SW103 must also
be set for 24 or 48 volts. All three must be set to the same
voltage. This switch setting may be done as part of the BD and
HV level setting procedures in this section.
Rectifier Restart
Group Isolation
In plants equipped with all SR-series rectifiers, the controller’s
two restart signals should not be isolated from each other.
Jumper P108 should be placed across pins 1 and 2 for all
SR-series rectifiers. For plants with mixed rectifier types the
jumper should be connected across pins 2 and 3.
