decimal position (DEC); for currents over 999A, place the
jumper or slide switch to the no-decimal position (NO DEC).
The controller will only work with the shunt sizes listed in Table
4-B. In battery plants with other shunt sizes, replace the shunt or
use an AKC1B circuit pack. When the AKC1B is used, use
Table 4-H instead of Table 4-B to configure SW109.
Battery on
Discharge
Threshold
The voltage threshold for the BD alarms is set with DIP switch
SW103. (See Figure 4-4.) Refer to Figure 4-5 or the label on the
113B cover plate for the DIP switch settings for the desired
alarm threshold. The same table of settings also appears on
schematic drawing SD83181-01 and on the assembly drawing
J85501E-2. The recommended threshold is approximately 1.0
volt below the float voltage for nominal 48-volt plants or
approximately 0.5 volt below float for nominal 24-volt plants.
Be sure to 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 the 113B. (See Figure 4-4.) The equalize shutdown is
controlled by DIP switch SW101 on the 113B. The equalize
shutdown level does not need to be set if equalize is hardware
disabled (see “Equalize Enable/Disable.”) The recommended
