ABORTED CHARGE
If charging cannot be completed normally,
charging will abort. When charging aborts, the
charger's output is shut off and the
CHARGING
flash. The digital display will show an error
code (see the Troubleshooting section for a
description of the error codes). To reset after
an aborted charge, unplug the charger from
the AC outlet, wait a few moments and then
plug it back in.
DESULFATION MODE
Desulfation could take 8 to 10 hours.
If desulfation fails, charging will abort and
the CHARGING
will flash.
COMPLETION OF CHARGE
Charge completion is indicated by the
CHARGED/MAINTAINING
LED. When pulsing, the charger has
switched to the maintain mode of operation.
MAINTAIN MODE
(FLOAT-MODE MONITORING)
When the CHARGED/MAINTAINING
(green) LED is lit, the charger has started
maintain mode. In this mode, the charger
keeps the battery fully charged by delivering a
small current when necessary. If the charger
has to provide its maximum maintain current
for a continuous 12 hour period, it will go into
abort mode (see Aborted Charge section).
This is usually caused by a drain on the
battery or the battery could be bad.
MAINTAINING A BATTERY
The XC75-CA, XC75W-CA, XC103-CA and
XC103W-CA charge and maintain both 6
and 12 volt batteries.
NOTE: The maintain mode technology
allows you to safely charge and maintain a
healthy battery for extended periods of time.
However, problems with the battery, electrical
problems in the vehicle, improper
connections or other unanticipated conditions
could cause excessive current draws. As
such, occasionally monitoring your battery
and the charging process is required.
USING THE ENGINE START FEATURE
Your battery charger can be used to jump
start your car if the battery is low. Follow all
safety instructions and precautions for
charging your battery. Wear complete eye
protection and protective clothing.
WARNING: Using the ENGINE START
feature WITHOUT a battery installed in the
vehicle could cause damage to the vehicle's
electrical system.
NOTE: If you have charged the battery and
it still will not start your car, do not use the
(yellow/orange) LED will
(yellow/orange) LED
(green)
Engine Start feature, or it could damage the
vehicle's electrical system. Have the battery
checked.
1. With the charger unplugged from the
AC outlet, connect the charger to the
battery following the instructions given
in the CHARGING A BATTERY IN THE
VEHICLE section.
2. Plug the charger AC power cord into the
AC outlet.
3. With the charger plugged in and
connected to the battery and chassis,
press the RATE SELECTION button until
the ENGINE START LED is lit.
4. Crank the engine until it starts or 3 seconds
pass. If the engine does not start, wait 3
minutes before cranking again. This allows
the charger and battery to cool down.
NOTE: During extremely cold weather, or if
the battery is under 2 volts, charge the battery
for 5 minutes before cranking the engine.
5. If the engine fails to start, charge the
battery for 5 more minutes before
attempting to crank the engine again.
6. After the engine starts, unplug the AC
power cord before disconnecting the
battery clamps from the vehicle.
7. Clean and store the charger in a dry
location.
NOTE: If the engine does turn over but
never starts, there is not a problem with the
starting system; there is a problem
somewhere else with the vehicle. STOP
cranking the engine until the other problem
has been diagnosed and corrected.
ENGINE STARTING NOTES
During the starting sequence listed above,
the charger is set to one of three states:
• Wait for cranking – The charger waits until
the engine is actually being cranked before
delivering the amps for engine start and will
reset if the engine is not cranked within 15
minutes. (If the charger resets, it sets itself to
the default start up settings). While waiting for
cranking, the digital display shows rdy.
• Cranking – When cranking is detected, the
charger will automatically deliver up to its
maximum output as required by the starting
system for up to 3 seconds or until the engine
cranking stops. The digital display shows a
countdown of the remaining crank time.
• Cool Down – After cranking, the charger
enters a mandatory 3 minute (180 second)
cool down state. The digital display indicates
the remaining cool down time in seconds. It
starts at 180 and counts down to 0. After 3
minutes, the digital display will change from
displaying the countdown to displaying rdy.
The CHARGING LED
• 6 •
will then be lit.
