Charger Operation - Liberty Pumps 441 Manuel D'installation

Cha r ger Opera ti on
The charger circuitry opens under severe overload. This condition
may occur if attempting to charge any severely discharged or
heavily sulfated battery. Once opened, the charger stops charging
for a short period and then automatically resumes charging. The
AMBER LED (Charging) will be OFF until charging resumes.
Overloading could be due to an external load; remove the load
condition prior to attempting to recharge the battery.
The charger has reverse battery and short circuit protection. If a
reverse battery condition exists, unplug charger from AC power
and reverse the connections.
The unit will automatically detect the battery internal cells
condition as well as battery sulfated conditions.
The charger has internal overheat protection. The charger will turn
off power until the temperature is down to a safe level, then
automatically start charging again. All LEDs will be off.
The charger is designed to charge 12 V lead acid batteries.
• Never charge lithium ion batteries on this charger.
• The charge time is dependent on the Ah rating of the
