correct, check and correct battery
/ load voltage (consider battery
surface charge, alternator, and
any connected equipment).

AC LED
1. Using a voltmeter, check that
AC input voltage and frequency at
AC input terminal block/breaker
are in the range 188VAC
–
428VAC / 47Hz
–
63Hz or that >
60VDC is present at DC output
terminal block/breaker and that
the DC polarity is correct. Correct
charger AC input and DC output
voltage as required.
2. If step 1 doesn’t resolve RED AC
light, remove both AC and DC
power for 1 minute, then reapply
power.
3. If steps 1 and 2 don’t resolve
RED AC light, a charger failure is
the likely cause. Replace charger.
DC LED
1. Check that charger battery
settings and alarms are set
appropriately for the application
and battery under charge.
2. If settings and alarms are
correct, check and correct battery
/ load voltage (consider loads and
any connected equipment).
3. If fault remains after the above
steps, check battery health.
Replace battery if weak.
