7 FAULT DIAGNOSIS
The charger is not operating
Check that the incoming AC supply is correctly connected and within
limits and check the integrity of any external fuse that may be fitted.
Ensure the charger is not being operated above the maximum
temperature specification.
Check the LED indications against the LED descriptions listed
elsewhere in this document.
Charge fail relay
continuously operated
Check the connected load of the charger is not reverse connected or
short circuit.
Batteries fail to charge
Check the batteries using the battery manufacturers
recommendations.
Charge time is too long
Typically a battery will charge from flat to 80% capacity in 16hrs when
when charged at C/10.
For example charging a 50Ah battery for 16hrs at 5A will charge the
battery to 80% of its full capacity.
Remember to take into account any other standing load such as
control panel requirements when calculating how much power is ‘left’
to charge the battery.
