The yellow light will be on and the meter will indicate low current. BATTERY CHARGE - After testing the battery, the control will select a charging rate suitable for the voltage and state of charge of the battery. A small battery, or a nearly charged battery will cause the charger to rapidly step down in current to avoid heating and gassing. FINISH CHARGE - In order to reach a 100 % state of charge on the battery, a 3 hour finish cycle has been programmed into the charger control. During this cycle, if the battery voltage does not change over a fixed period of time the charger shuts off and the green light comes on. TIME OUT - An 11 hour timer will terminate the charging cycle if for some reason 100 % state of charge has not been reached. COOLING FAN - When charging current exceeds 10 amps the cooling fan will come on to keep the electronics from overheating. Below 10 amps the fan shuts off. The fan will also come on briefly when the AC power first comes on. BATTERY MAINTAINER - If the charger is left connected to the battery, it will begin recharging if the terminal voltage falls below 12.44 VDC. It is recommended that the electrolyte level be checked regularly when charging batteries for an extended period of time. OPERATING PROCEDURE: 1. Plug AC cord into outlet. Turn AC Power Switch on back of cabinet to the ON « I » position. The Red light should come on and the fan will run briefly. 2. Put selector switch in the CHARGE position. 3. Connect the BLACK clamp to the negative (-) terminal of the battery. Connect the RED clamp to the positive (+) terminal of the battery. The GREEN light should come on for 3 seconds. 4. The YELLOW light will come on when the GREEN light goes off. After a 6 second battery test charging will begin. The amount of charging current can be observed on the meter. 14 5. The battery is charged when the GREEN light is blinking. If a 100 % state of charge is not needed the battery can be used when the meter indicates low charging current. NOTES: a. If the charger is connected to a battery which will not accept a charge, the charging cycle will end and the GREEN light will blink. b. If the charger is connected to a fully charged battery the charger will shut off and the GREEN light will blink. c. If the clamps are removed during the battery test sequence the charger will shut off and the GREEN light will blink. d. It is best to reset the charger control before beginning to charge another battery. This can be accomplished by pulling the AC Power Switch OFF « F » then ON « I » again. e. Any time a malfunction is suspected reset the control by turning the AC Power Switch OFF « F ». VEHICLE STARTING: 1. Charge the battery for a minimum of 10 minutes using the procedure above. 2. Put the selector switch in the ENGINE START position. 3. Attempt to start the vehicle. If the engine does not start, put the selector switch back to the CHARGE position for another 10 minutes before trying again. NOTE: The output circuit breaker may open during the engine start. It will reset in a few seconds and battery charging will continue. WIRING DIAGRAM 15 16 MAINTENANCE INSTRUCTIONS Worn clamps, cords or cables should be replaced.
