Troubleshooting
The IBC320 charger is designed to provide years of reliable service. However in the event that
it does not seem to be operating correctly, here are some things you can check.
AC Present LED does not come on.
First make sure any external circuit breaker is ON. Unplug or turn off the external power to
the charger. Plug any other device into the AC receptacle or use a multimeter to make sure AC
is present. Remove the fuse and check for continuity with a multimeter. If the fuse is open,
replace it with the recommended fuse listed on the label and reconnect or turn the power back
on. The AC Present LED should come on. If it does not, then there is an internal failure and the
charger will have to be returned for service.
Battery Overtemp Indication
The sensor connected to the battery indicates that the battery temperature has exceeded the
safe maximum limit. The charger will turn off its outputs until the battery temperature returns
to a safe level, at which time the charger will resume normal operation.
Battery Low Voltage Indication
If the battery is seriously discharged, and the charger voltage drops below 85% of nominal
(ie. 10V for a 12V charger), the charger will alternate between its normal display and the Low
Battery Voltage display until the battery voltage exceeds 85% of nominal.
Battery Fail Indication
If the charger determines that the battery is defective and will not accept a charge, the
charger will stop attempting to charge the battery. This condition requires action on the part
of the user to replace the battery before the charger will resume normal operation. Cycling the
power switch to Off and back On again in any way will reset this condition and the charger
will attempt to recharge the battery again.
Charger Overtemp
If the charger gets too hot, it will switch to Standby until it cools sufciently to resume normal
operation.
Low Input Volts
If the input voltage drops below the minimum voltage necessary for normal operation, the
charger will show display. The charger will switch to Standby and wait for the voltage to
recover.
Charger Failed
If the processor detects a condition that prevents the charger from operating, it will show this
display. Try cycling the power a couple of times to see if that clears the problem. If it does
not clear the display the charger will have to be returned for repair. More information on the
nature of the fault can be determined by connecting to the charger using a laptop and using
the Power Wizard program to see if a more detail error message is there.
