Battery Charger Troubleshooting
No Lights at all
No Lights at all indicate that AC power to the charger is
not connected or that the AC voltage is too low. It could
also indicate an internal failure in the charger.
1.
Check the connections to AC power. Check for
AC voltage between 90 and 260 VAC at the char-
ger.
2.
If the AC voltage is verified to be correct at the
connection to the charger, and the charger still
displays no lights at all, return the charger for
service.
FAULT LED Flashing
The Fault LED flashes to indicate the micro-controller
inside the battery charger has detected a fault. The fault
detected is indicated by the number of flashes. Count the
number of flashes to determine the fault.
With any battery system, the most common problem will
be a faulty battery connection. Because of the high likeli-
hood of a battery connection problem, it is always worth-
while to confirm that all connections are good before
checking for any other problems.
[1 Flash] - High Battery Voltage
1.
Indicates a high battery voltage. Check that the
battery charger voltage is consistent with the
battery pack voltage. The first two digits of the
four digit model name indicate the battery volt-
age the charger supports.
2.
Check for wiring errors.
3.
This fault will automatically clear and the char-
ger will restart charging when this problem is
removed.
4.
High battery voltage could also occur if there is
another source charging the battery. Disconnect
any other sources during charging.
5.
If this problem does not clear after the battery
voltage is confirmed to be less than 2.4V per cell,
return the charger for service.
[2 Flashes] - Low Battery Voltage
1.
Indicates either a battery failure, no battery con-
nected, or a lower than expected battery volt-
age. Check the battery and battery connections.
2.
Check the nominal battery voltage. The first two
digits of the four digit model name indicate the
battery voltage the charger supports. Confirm
that a nominal battery voltage is the same as the
charger voltage.
3.
This fault will clear automatically when the low
battery voltage problem is rectified.
4.
If this problem does not clear after the battery
voltage is confirmed to be higher than 1.0V per
