The switch on the left selects a 2 Stage or 3 Stage charging profile.
A 2 Stage charging profile consists of charging the battery at a constant current until the
battery voltage reaches the Float Voltage. The charger will then maintain the battery at the
Float Voltage and the current will gradually taper down. The recharge is considered complete
when the charging current drops to 10% of the rated current of the charger.
A 3 Stage charging profile consists of charging the battery at a constant current until the
battery voltage reaches an elevated voltage called the ‘Absorption Voltage’. The charger will
then maintain the battery at the Absorption Voltage until the charging current drops to 10% of
the rated current of the charger OR a maximum of 3 hours (adjustable in the custom charging
profile).
The switch on the right tells the Charger what to do when recharging is complete.
Moving the switch to the Left tells the charger to Rest or switch to Standby when the recharge
is complete. The charger will remain in Standby until the power is cycled (either by the front
panel ON/OFF button, the Power Switch on the rear panel or by cycling the external breaker)
OR until the battery voltage drops to 90% of the rated voltage of the battery. Under any of
these conditions, the charger will initiate a new recharge cycle. This is the position the switch
MUST be in to meet the California Energy Commission regulations.
Moving the switch to the Right tells the charger to maintain the battery at the Float Voltage
indefinitely. This will ensure that the battery is always fully recharged and ready for service. A
new recharge cycle will be initiated only if the charger is providing full rated current to keep
the battery at the Float Voltage OR if the power is cycled by any one of the three ways as
described above.
