2000 ECS-12U Controller J85501E-2
2 - 14 Product Description Issue 3 July 1998
The TR signal input to the controller may also be used for other
on/off control of rectifiers by an external control device. (See
ECS Controller Options Product Manual, Select Code
167-790-109.)
Float and
Equalize Control
Some Lineage
®
2000 rectifiers are capable of battery equalize
charging in addition to normal float charging. The equalize
feature may be used to recharge flooded type, i.e., non-sealed,
batteries in less time than when the float voltage is used. Some
battery manufacturers recommend equalize charging after a
discharge; others recommend periodic equalizing of batteries.
NOTE Use of equalize on sealed lead acid batteries is NOT
recommended.
The ECS-12U controller has several methods of controlling the
equalize function in plants that are so equipped:
Hardware Disable: A movable jumper (P106) on the
113B may be used to disable the equalize function and
lock the plant in float mode. This is especially important
for plants equipped with sealed-type or valve-regulated
batteries and for plants powering equipment sensitive to
high voltages.
Batteryless plants also have no need for the equalize
function. The controller is always shipped with equalize
disabled by this jumper to prevent accidental
misapplication of the equalize feature. (See Section 4,
“Hardware Setup” for details.)
Local Manual Control: A momentary toggle switch on
the controller front panel may be used to switch the
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 113B may interface with an
external equalize control panel. Since the basic controller
with the 113B and RIB boards has no built-in on/off timer
(see Section 4, “Basic Controller Wiring”) the 113B 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 (CP3) in
conjunction with the logic functions provided for the CP3
