2 - 14 Product Description
Issue 6 August 1998
intervention. 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-6 controller and the rectifiers in the
plant containing the ECS-6 controller. This board produces
Major and Minor fuse alarms for the fuses on the board and 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-6 controller.
Power and Sense
Voltage Fusing
The LVD/Fuse Board has 12 fuses to distribute power and sense
voltages:
•
F501-F506 provide battery sense voltage to the regulation
leads of the rectifiers.
•
F507 provides power and plant voltage sensing to the meter
circuits of the 113A2 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
control board.
•
F510 provides power to the controller interface circuits on
the rectifiers.
•
F511 provides power to the ABS leads of the 113A2.
•
F512 provides power to the circuitry on the 113A2 that is
not powered by F507 or F509.
