Equalization Charging
The C-Series offers either manual or automatic triggering of
the equalization charging process. Equalization charging is
the deliberate process of charging a battery (or battery bank)
at a high voltage for a set period of time to remix the
electrolyte and destratify the internal plates. Equalize
charging helps to remove sulfate buildup on the battery plates
and balances the charge of individual cells.
Equalization charging holds the voltage above the B
ULK
setting for 2 hours by 1 volt for 12-volt systems, 2 volts for
24-volt systems, and 4 volts for 48-volt systems.
The default setting for this feature is M
ANUAL. Automatic
equalization is enabled by moving the jumper located on the
right side of the circuit board above the reset switch to the
appropriate A
UTO pin set. See Figure 2-18
When automatic has been selected, an equalization charge
will occur every 30 days.
During the equalization process, the status LED indicates
equalization by alternately blinking green and red.
:
CAUTION: Damage to Batteries
Equalization should be done for standard electrolyte, vented
batteries only. Sealed, GEL cell, or NiCad batteries should not be
equalize-charged. Consult your battery supplier for details on
equalize-charging for the battery type in your system.

Important: The auto equalization period is reset when DC
power is removed from the controller.
