2000 ECS-12 Controller J85501D-2
2 - 14 Product Description
Issue 3 August 1998
External Timer Panel: The 113B may interface with an
external equalize control panel. Since the basic controller
with CP1 has no built-in on/off timer, CP1 may be
connected to a timer panel to automatically terminate
equalize without manual intervention (see Section 4,
“Wiring”). Note that this control method is overridden
when equalize is hardware disabled.
Microprocessor Control: CP2 is equipped with a variety
of software features for float/equalize control. These
features are also disabled by the hardware strap on CP1.
(See ECS Controller Options Product Manual, Select Code
167-790-109.)
These control methods may be used interchangeably. For
example, the front panel switch may be used to initiate equalize,
while an external timer may turn it off.
LVD/Fuse
Board
The LVD/Fuse board provides fused power and voltage sense
distribution for the ECS-12 Controller and the rectifiers in the
plant containing the ECS-12 Controller and low power
distribution for customer applications. This board produces
Major and Minor fuse alarms for the fuses on the board, as well
as for plant distribution circuit breakers and user selectable
interfaces. It also provides low voltage detection circuits that
control the Low Voltage Disconnect Contactor, an optional
feature on many of the plants that use the ECS-12 Controller.
Power and Sense
Voltage Fusing
The LVD/Fuse Board has up to 18 fuses to distribute power and
sense voltages:
•
F501-F506 and F513-F518 provide battery sense voltage to
the regulation leads of the rectifiers.
•
F507 provides power and plant voltage sensing to the meter
circuits of the 113B and optional microprocessor circuit
pack.
•
F508 provides power to the optional microprocessor and
datalogger circuit packs.
•
F509 provides power to the rectifier interface circuits on the
113B.
