2000 ECS-6 Controller J85501D-1
Issue 6 August 1998
Installation and Setup 4 - 7
Voltage Selection
As shown in Figure 4-1, there are four jumpers for voltage
selection. Verify that all of the jumpers are in the correct
positions. Factory-mounted controllers are typically preset for
the proper plant voltage. The installer, however, should check
these settings.
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 procedure in “Battery on Discharge Threshold”
and “High Voltage Shutdown Thresholds.”
NOTE
Early vintage 113A Control Units (stamped as Series 1) are
suitable for positive ground plants only (i.e., -48V or -24V).
Equalize
Enable/Disable
The equalize jumper, P106, shown in Figure 4-2, is factory set in
the DISABLE position (pins 1 and 2). If the plant is equipped
with equalize-type rectifiers and flooded-type batteries, this
jumper may be moved to the ENABLE position (pins 2 and 3).
When equalize is enabled, the front panel switch and other
equalize control methods can be used to initiate equalize
charging. If the jumper is removed or misplaced, equalize is
DISABLED.
Automatic
Restart
Enable/Disable
The restart jumper, P105, is factory set in the ENABLE position
(pins 1 and 2). (See Figure 4-2.) This setting allows the
controller to attempt to restart rectifiers after a high voltage
shutdown. For one rectifier plant without battery reserve, the
jumper should be moved to the DISABLE position (pins 2 and
3). Manual intervention will be required to restart the rectifier in
such an application.
CAUTION
If the P105 jumper is removed or lost, the automatic restart
function is DISABLED.
Ammeter Scale
DIP switch SW109 is used to select the scale for the plant current
meter. Factory-mounted controllers in bays equipped with plant
shunts are preset to the proper ammeter scale. Use the label on
the cover plate of the 113A2 to check the DIP switch settings
versus the plant shunt rating. If the plant shunt rating is 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 113A2 control unit.)
