Theory of Operation
IQ SERIES OWNERS MANUAL - 29 -
This setting is sufficient to keep the battery charged, but not so high as to boil or over-charge the
batteries. The charger will remain in Float Stage until the battery will accept the Bulk Charge Output
Amps selected.
Equalization Cycle
This manually initiated cycle provides a 1 hour equalization charge at the Bulk Voltage level to boil the
battery. This removes the sulfate build-up on the battery plates, and is used only on flooded lead acid
batteries. Refer to the battery manufacturer for frequency recommendations.
WARNING: DO NOT USE WITH SEALED OR LEAD CALCIUM MAINTENANCE FREE BATTERIES.
The Equalization Charge Cycle is initiated by switching Program Switch 3 from OFF to the ON position. The
Equalize Cycle is automatically terminated after 1 hour. The Equalize Cycle will be manually terminated by turning
the Program Switch 3 to the OFF position or by turning the Main ON/OFF Switch OFF or by turning shore power
OFF.
