Fault Indications And Troubleshooting - Exide 12/15 User Manual

is equipped with a cut-out function that interrupts the process, at
the same time as the fault is shown by the LED shining a constant
red. NOTE: This alarm can be triggered when charging batteries
that have capacities exceeding the recommended battery size, or
in connection with other equipment drawing current (parallel loads)
being connected to the battery during charging.
Batteries are damaged when charged at high temperatures. For
this reason, the charger features a safety function that terminates
charging when the temperature is too high, approx. 50 °C.
Information about faults and fault indications is explained in the
table below.

1.
to the battery terminals.
Probable cause: If the cable clamps are incorrectly connected to the
battery, the polarity reversal protection will be activated and charging
will not start.
Action: Check that the charger is connected using the correct polarity.
2.
Fault: Charging does not start, i.e. the lamp continues to shine,
and the yellow LED does not change to the steady yellow light.
Probable cause: The battery voltage is too low to start the char-
ger. This may be because the battery is worn or faulty or has been
completely discharged.
Action: Try to connect the 13.7 V Supply mode for a little
while (max. 10 min). Restart charging. This usually works
if the battery is really heavily discharged, but otherwise in
good condition.
3.
Fault: Charging started normally, but did not complete. The red
LED lights, the yellow LED flashes and charging is terminated.
Probable cause 1: Defective battery. The battery has a fault that
does not permit it to be charged, e.g. a short circuit.
Action: Replace the battery.
