Fault Indications And Troubleshooting - Exide 12/7 User Manual

type of battery, the charger is equipped with a cut-out function that
interrupts charging, at the same time as the fault is shown by the
LED lighting constantly red. NOTE: This fault alarm can be trig-
gered during charging of batteries that have capacities above the
recommended battery size, or in connection with other equipment
drawing current (parallel loads) being connected to the battery
during charging.
Batteries can be damaged by being charged at high temperatures,
so the charger has been fitted with a safety function that interrupts
charging when temperatures are too high, approx. 50 °C.
Information about faults and fault indications is explained in the
table below.

Fault: The LED shows constant red when the charger cable
1.
clamps are connected 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 LED does not change to the constant 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: The battery has a fault that does not permit
it to be charged, e.g. a short circuit.
Action: Replace the battery.
