2000 ECS-12U Controller J85501E-2
Issue 3 July 1998 Product Description 2 - 15
will enable an automatic equalize function. Note that this
control method is overridden when equalize is hardware
disabled.
Microprocessor Control: The microprocessor board
(CP2) is equipped with a variety of software features for
float/equalize control. These features are also disabled by
the hardware strap on the 113B. (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 Board
Major and Minor Fuse Alarms are generated by the fuses on the
board, as well as for plant distribution fuses, circuit breakers and
user-selectable interfaces.
The fuse board contains six fuses for power and sense voltage
distribution in the controller, 12 fuses for battery sense voltage
to the regulation leads of the rectifiers, three fuses for user
defined low power distribution, and three spare fuse holders.
A 12-position terminal block is also available for connection to
external Major and Minor Fuse Alarm inputs and for connection
to the three low power distribution fuses. See Table 4-E for
terminal block (TB501) designations.
There are three fuse board codes: BCB2 for -48V applications
(Low Voltage Disconnect option), BCB5 for -48V applications,
and BCB6 for +24V applications.
