2000 ECS-6U Controller J85501E-1
Issue 4 August 1998
Product Description 2 - 15
rectifiers in the plant from float mode to equalize mode
and back again. This control is disabled when equalize is
hardware disabled with the jumper described above.
External Timer Panel: The 113A2 may interface with an
external equalize control panel. Since the basic controller
with the 113A2 and RIB boards has no built-in on/off
timer (see Section 4, “Wiring”) CP1 may be connected to a
timer panel to automatically terminate equalize without
manual intervention. For example, use of the control relays
on the datalogger board in conjunction with the logic
functions provided for the datalogger board will enable an
automatic equalize function. Note that this control method
is overridden when equalize is hardware disabled.
Microprocessor Control: The microprocessor is
equipped with a variety of software features for
float/equalize control. These features are also disabled by
the hardware strap on the 113A2. (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.
Fuse Alarm
Board (FAB)
The BAD8 FAB provides fused power and voltage sense
distribution for the ECS-6U controller and the rectifiers in the
plant containing the controller. Major and
Minor
Fuse Alarms are
generated by the fuses on the board, as well as for plant
distribution circuit breakers and user selectable interfaces.
Power and Sense
Voltage Fusing
The fuse alarm 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.
