Fault Finding
Power Supply fault
A power supply fault is indicative of one or more of the following faults: -
Loss of Mains power
Check that 230V AC is present at the mains terminal block
Check mains fuse
Check charger fuse FS1.
Loss of Battery power
Check that 2 X 12V batteries are fitted in series to give 24V backup
Check battery fuse
Check that battery connections are secure.
Check that the batteries are not over 5 years old
Loss of Charger
The Power supply will monitor the charger circuit. In the rare event of a component failure that affects the charger,
the PSU will bring up a fault.
Loss of Battery Capacity
The Power supply will monitor the Battery condition. If it detects a high internal resistance, which usually means a
loss of capacity in the battery, it will bring up a fault.
