2000 ECS-6U Controller J85501E-1
4 - 8 Installation and Setup
Issue 4 August 1998
The controller works only with the shunt sizes listed in Table
4-C. In battery plants with other shunt sizes, replace the shunt or
use an AKC1B circuit pack. If an AKC1B is used, configure
SW109 according to Table 4-H instead of Table 4-C.

Discharge
Threshold
The voltage threshold for the BD alarms is set with DIP switch
SW103. Refer to Figure 4-6 or the label on the 113A2 cover
plate for the DIP switch settings for the desired alarm threshold.
The same table of settings also appears on the schematic drawing
SD-83122-01 and on the assembly drawing J85501E-1. 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 also 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 CP1. (See Figure 4-5.) 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 (see “Equalize Enable/Disable”). The
recommended shutdown levels are approximately 1.0 volt above
