BATTERY CHARGING
NOTE: The FP3000-12 is ON whenever AC
power is connected to the charger input. The
charger can be turned OFF using the
CHARGE switch on the front of the unit. This
sequence will occur each time external AC
power is available. The charger can be turned
ON/OFF using the Remote Control Panel.
Each time the battery charger is engaged, the
three-stage charger proceeds automatically,
resulting in an efficient complete charge and
safe battery maintenance. Use of the Remote
Control Panel provides the ability to periodically
apply an equalizing charge.
Refer to Remote Control Panel owner’s
manual for more information.
The battery charger stages are:
Stage 1 - Bulk Charge During the bulk
charge stage most of the energy that has been
consumed during discharge is returned to the
battery bank. This phase is engaged as soon as
the battery charger is activated. Full rated charger
current is delivered to the battery bank until the
acceptance charge voltage limit is reached.
This results in a relatively rapid recharge.
Generally, a wet cell battery bank should not
be charged at a rate that exceeds 25% of its
capacity.
