Operating The Charger - Guest 28003 Owner's Manual

3. OPERATING THE CHARGER

The LED Function Chart describes the charging process for any of chargers listed above.
Display
When the yellow LED is on, it indicates that your batteries are discharged and
Y ellow
is recharging them at the "Charging" rate (stage 1). This charging rate is
specified (3,5,8) Amps.
Green
While the yellow LED is on, the voltage measured (with the charger on) will be
approximately 22.0 – 26.0 Volts.
If the yellow LED stays on for more than 24 hours, the charger will shut down
the output automatically and green LED will become flash, refer to Problem 2
in the troubleshooting section in this manual.
When both the green and the yellow LED's are on, it is charging at the
Y ellow "Finishing" rate. (stage 2). During this second charging stage, the charger
holds the battery voltage at approximately 29 VDC, and then gradually
Green reduces the amount of current (Amps) it delivers to the battery. By doing this,
the battery is able to "absorb" the last 10% of charge as quickly as possible
without becoming overheated.
If both lights stay on longer than 6 hours, the charger will shut down the
output automatically and green LED will become flash, refer to Problem 2 in
the troubleshooting section in this manual.
When the battery approaches full charge, the charger switches into its third
charging stage, gradually reducing the current fed to the batteries to as low as
0.1 Amps. At the same time, it reduces its output voltage to a "Float" or
Y ellow
"Ready" charging rate of approximately 27.1 VDC, indicated by the green LED
light.
Green
batteries, keeping them fully charged and ready until needed. Now you can
store your batteries at full charge indefinitely without overcharging. The green
LED indicates that your batteries are now fully charged and ready for use.
If the green LED stays on when your battery is known to be low, refer to
Problem 1 in the troubleshooting section in this manual.
