Associated Equipment 9520GS owner manual Opera Ting Instructions, Operating Procedure

d.Discontinue charging when the specific gravity of the electrolyte reaches 1,260 or above. A temperature compensating hydrometer should be used for this reading. Discontinue charging if the battery begins to gas excessively or when the temperature of the electrolyte reaches approximately 590 C. Do not overcharge the battery.

TING INSTRUCTIONS

*CONTINUOUS RED LIGHT - Indicates AC power is on.

*CONTINUOUS GREEN LIGHT - Indicates correct connection. If when battery is connected, the green light does not light, check for proper polarity or poor connections. If the battery voltage is below 2 volts the green light will not come on.

*CONTINUOUS YELLOW LIGHT - Indicates charging.

*BLINKING GREEN LIGHT - Indicates charging is complete.

NOTES:

THREE SECOND DELAY - To avoid sparking, the charger control tests for correct polarity before applying current to the battery. When connected properly, the green light will come on for 3 seconds before the yellow light comes on.

BATTERY TEST - After the 3 second delay the charger control will begin a 6 second battery test. 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.
