20.CHARGE PERIOD

The approximate required time 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 times the number of Amps supplied by a battery to a load and normally indicated on the battery. For example - if a load was connected to a battery, which drew 7 Amps 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 of the charge rate add 25 percent to the charge time.

OPERATING 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 1 volt the green light will not come on.

*CONTINUOUS YELLOW LIGHT - Indicates charging.

*BLINKING YELLOW LIGHT - Indicates battery is near end of charge and is in the float charge mode.

*BLINKING GREEN LIGHT - Indicates charging is complete and is in the standby mode.

NOTES:

FIVE 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 5 seconds before the yellow light comes on.

BATTERY CHARGE - After the 5 second delay the GREEN light will go off and the YELLOW light will come on. The control will select a charging rate suitable for the voltage and state of charge of the battery.

FINISH CHARGE - In order to reach a 100% state of charge on the battery, a finish charge cycle has been programmed into the charger. During the finish cycle, the yellow light will blink. If the battery is good, there will be enough charge in an automotive type battery at this time to start a vehicle when the yellow light is blinking. If desired, the battery can be removed and replaced in the vehicle. The vehicle alternator will finish charging the battery.

NOTE: To avoid sparking, always pull the AC cord plug from the outlet receptacle to disconnect charger power before removing the output clamps.

SMALL BATTERY CHARGING - In order to properly finish charge a small battery (1 amp-hour or less), it is necessary to reduce float charge current during the finish charge mode. For this reason, it is recommended that batteries smaller than 1 amp-Hr be charged with the selector switch in the SMALL battery position. The charger will not harm a small battery if charged in the LARGE battery position, but it may not reach 100% state of charge before charging is terminated.

BATTERY MAINTAINER - If the charger is left connected to the battery, it will begin recharging if the terminal voltage falls below 12.5 VDC. It is recommended that the electrolyte level on flooded batteries be checked regularly when charging batteries for an extended period of time.

OPERATING PROCEDURE:

1.Put selector switch in the position which matches the size of battery being charged.

2.Plug AC cord into outlet. The Red light should come on.

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 will come on for about 5 seconds.

4.The YELLOW light will come on when the GREEN light goes off and charging will begin.

5.The battery is between 80% and 99% state of charge when the YELLOW light blinks. The charger is in the finish charge mode.

6.The battery has been fully charged when the GREEN light is blinking. No current is supplied to the battery and the charger is in the standby mode..

NOTES:

a.If the charger is connected to a battery which will not accept a charge, the charger will continue to attempt to charge it as long as the battery is connected. Discontinue charging after a reasonable amount of time or if the battery feels hot.

b.If the charger is connected to a fully charged battery the charger will go into the finish charge mode then shut off and the GREEN light will blink.

c.Any time a malfunction is suspected reset the control by pulling the AC plug.
