POSSIBLE CAUSE
|
SOLUTION
|
The
battery is connected and the charger is on, but is not charging.
|
The charger is not in char¬ger
mode.
|
Press START/STOP button for the
battery that is connected to the charger.
|
The
indicator lights are lit in an erratic manner, not explained in “Using Your
Battery Charger” section.
|
A button may have been pressed
when the charger was plugged in.
|
Make sure nothing is touching
the control panel, then unplug the unit and plug it in again.
|
“bAd bAt” in Display; CONNECTED LED
lit.
|
The charger is in Abort Mode.
The battery may be bad.
|
See the “USING YOUR BATTERY
CHARGER” section.
|
See
Aborted Charge in the “Operating Instructions” section.
|
This will happen if the battery
did not reach full charge within 24 hours. May be due to a very large battery
or bank of batteries requiring more power than the charger can deliver in 24
hours. The charger is in abort mode. The battery may also be faulty.
|
Reset the charger by unplugging
it. Select the desired battery type again, if necessary.
|
The
charger is making an audible clicking sound.
|
The charger has a relay that
turns the current on and off to the battery.
|
No problem, this is a normal
condition.
|
The measured current is much lower than what was selected.
|
The charger reached the maximum
voltage and is reducing the current.
|
No problem, this is a normal
condition.
|
The
charger detected an over-temperature condition and has reduced the current to
allow the unit to cool.
|
Make sure the char¬ger does not
have the side ventilation holes blocked. Move the charger out of the sun and
into the shade.
|
The
charger was unplugged from the wall but the display is still on.
|
The battery is supplying the
power to the display.
|
Disconnect the battery.
|
While
charging the battery, the battery stays at a certain % (ex. <65%).
|
The % display may not change at
a steady rate.
|
DO NOT UNPLUG OR CHANGE
SET¬TING. Be patient and let the charger finish. This is normal.
|
When the
charger is unplugged or the settings are changed, the number increases or
jumps to 100%.
|
The battery voltage is still
high from a partial charge.
|
Wait for the voltage to settle
before resum¬ing the charge. Try to charge at a lower charge rate. Turn on
the lights to remove the surface charge.
