MANUAL-AUTOMATIC SWITCH
Charging may be either Manual or Automatic.
OPERATION
- The charger contains a three-position switch that
determines its mode of operation. There are two AUTOMATIC
positions and one MANUAL position.
MANUAL CHARGING
When the MANUAL position is selected the charger will con-
tinue to charge and will NOT shut off when the battery is fully
charged. The GREEN LED will glow after the charging current
has stabilized at some small value but the charger will continue
to charge.
NOTE:
As a safety precaution, there is a 24-hour maximum time
limit in ALL modes (MANUAL and AUTOMATIC). After 24 hours,
the charger will automatically switch to MAINTAIN MODE, how-
ever, damage may have ocurred to a battery in the MANUAL
position by this time.
LED DISPLAY
BATTERY CHARGER CONTROLS
LED Indicators: The battery charger has three LED lights. They indicate different functions.
RED LED
- A steady glow indicates
POWER ON and proper connection to
the battery. A flashing red LED indicates
the battery is NOT correctly connected
and the connections need to be checked.
The red LED will also flash several times
when the switch position is changed.
(For an explanation of a rapidly flashing
red LED, see "Desulfation Mode" in
Battery Charger Controls section.)
YELLOW LED
- A steady glow indicates
when the charger is CHARGING in the
Automatic modes. It will flash if the
charger goes into Desulfation mode. In
Manual mode to indicate charging, the
yellow LED will flash rapidly.
GREEN LED
- When in Automatic mode,
the battery when FULLY CHARGED will
move to the Charged/Maintain position
and the green LED will flicker. This
indicates that Float-mode Monitoring is
keeping your battery maintained at full
charge.
NOTE
: When charging in Manual mode, the battery needs to be monitored frequently. The charger will NOT sense the battery at full
charge and shut off automatically. You must disconnect the charger when the battery is at Full Charge or battery damage will occur.
As a safety precaution, after 24-hours of charging in either Automatic or Manual mode, the charger automatically switchs into Float-
Mode Monitoring. However, by this time, if using the Manual mode damage might have already occured to the battery. DO NOT rely on
this function to tell you if your battery is fully charged. To continue the charging process, if the charger switches to Float-mode
Monitoring, reset the charger by moving the switch to any position then repositioning it to the mode you want to use.
WARNING:
In the MANUAL position, the charger will continue to
charge even after the battery is fully charged.
WARNING:
Overcharging can damage the battery.
AUTOMATIC CHARGING
When an AUTOMATIC position is selected, the charger goes
through a three-step charging process. During the BULK charge
phase, the charger attempts to deliver 12 amps of current to the
battery until the battery voltage levels off. At this point, the charger
enters the ABSORPTION charge phase. In this phase, the
charger will hold the battery voltage constant and let the battery
determine the charging current. When the charging current sta-
bilizes, the charger will continue to charge for a couple hours to
bring the battery up to full charge. The charger will then auto-
matically enter the MAINTAIN MODE - Float-Mode Monitoring.
During this phase, the charger will hold the battery voltage con-
stant at 13.2 volts to guard against self-discharge of the battery.
The charge current will typically be a few tenths of an amp.
