12.OUTPUT CONTROL

12.1This battery charger is equipped with a self-resetting circuit breaker. This device protects the charger from temporary overloads. In the event of an overload, the circuit breaker will trip open, and after a short cooling off period, will reset automatically. This process is known as cycling and can be recognized by an audible clicking sound.

12.2This battery charger is equipped with an electronic control circuit which automatically governs the charge rate to your battery. The charger will satisfactorily charge maintenance-free and conventional batteries. The PS-1022MA (Manual Position) and the PS-2100MA (6V 15A Position) are not controlled by the control board and must be monitored. Overcharging can cause damage to your battery.

13.CHARGE PERIOD

The approximate time required to bring a battery to full charge state depends upon the number of ampere hours (Ah) depleted from the battery. Ahs are determined by multiplying the number of hours by the number of amps supplied to a load.

For example, if a load was connected to a battery, which drew 7 Amp for a period of 5 hours, the battery will have supplied 35 Ah. The approximate recharge time would then be calculated by dividing the 35 Ah depleted from the battery, by the ampere charge rate of the charger. To allow for tapering off of the charge rate, add 25% to the charge time. Indications of a fully charged battery are:

1.When the meter indicates an intermittent current flow to the battery.

2.A hydrometer reading of the specific gravity of the electrolyte (fluid) of a battery in good condition should be between 1.250 and 1.285.

3.When a battery reaches 80–85% of full charge, bubbles will appear on the surface of the fluid. As the battery nears full charge, bubbling will become more noticeably active.

4.The time required to charge two 6 Volt batteries connected in series will be the same as for one 12 Volt battery of equivalent size.

5.DO NOT charge two 12 Volt batteries in parallel.

NOTE: Model PS-1275A – This model turns off when the battery is at full charge and turns on again automatically when the battery needs to be recharged.

Models PS-1022MA and PS-2100MA: These models do not turn off when in the “manual” position of the “type of battery” switch. Monitor the charger frequently when charging a battery in the manual position.

14.MAINTENANCE INSTRUCTIONS

14.1Before performing maintenance, unplug and disconnect the battery charger (see Sections 6, 7 and 8).

14.2After use, unplug the charger and use a dry cloth to wipe all battery corrosion and other dirt or oil from the terminals, cords, and the charger case.

14.3Servicing does not require opening the unit, as there are no user-serviceable parts.
