3.1.7 Forced charging
There is provision for the battery chargers to provide
a forced charge to the batteries. The Forced Charge
function will only activate immediately after applying
power to the charger with DIP Switch 8 in the ON
position and a battery connected.
When the charger is in the forced charge mode, it will
attempt to recover a battery by delivering 10 amps. If the
battery does not reach the minimum battery voltage (8 Volts
for a 12 Volt system; 16 Volts for a 24 Volt system) within
5 minutes, the recovery attempt will terminate. Once the
battery reaches its minimum battery voltage, the normal
charge sequence will commence.
Forced charging will only occur once per battery charger
power cycle.
