OPERATING THE CHARGER

The LED Function Chart below describes the charging process.

NOTE:

The LEDs discussed below in the table are the Charge Status LEDs.

NOTE:

The AC Present LED green#2 is lit at all times when AC is connected, and off when AC is

not connected.

Display

Operating Condiiton

Red = on

When the red LED is on, it indicated that your battery is discharged and
the model 2820-24 is recharging the battery at the "Bulk" rate (Stage 1).

Yellow = off

This charging rate is approximately 20 Amps.
While the red LED is on, the voltage measured (with the charger on) will

Green#1= off

be approximately 23 to 28 Volts.

If an excessive amount of time is taken to complete this stage, the
charger will time out and present a fault indicator. (See section 5.)

Red = on

When both the yellow and the red LED's are on, it is charging at the
"absorption" rate. (Stage 2). During this second charging stage, the

Yellow = on

charger holds the battery voltage at approximately 29 VDC, and
gradually reduces the amount of current delivered to the battery.

Green#1 = off

If an excessive amount of time is taken to complete this stage, the
charger will time out and present a fault indicator. (see section 5)

Red = on

When all three charge status LEDs are on, the model 2820-24 is
charging at a "Finish" rate of 10 Amps, (Stage 3). The "Finish" stage will

Yellow = on

charge the battery up to approximately 30.5-31 VDC.

Green#1 = on

If an excessive amount of time is taken to complete this stage, the
charger will time out and present a fault indicator. (see section 5.)

Red = off

When the green#1 LED is on, and red and yellow are off, the charge
cycle is completed and the battery is ready for use. At least 100% of

Yellow = off

charge has been returned to the battery. If the battery voltage falls below
approximately 24 VDC, the charger will automatically restart the charge

Green#1 = on

process.
