AC good, output
power limited
1. Charger power is
reduced to protect
charger due to high
temperatures
1. Check for obstructions on
ventilation openings
2. Ensure that all covers are
installed as directed in manual.
3. Reduce operating environment
temperature. Charger will
automatically increase power as
temperature is lowered.

AC good, load
share fail
1. Charger output
settings do not
match between
chargers
1. Check that individual charger
settings are identical. Adjust as
required. After making any
adjustments, unplug and re-plug
load share cable from charger.

1. Too many devices
on the SENSbus
network
1. Ensure that less than max
allowed number of devices is on
the SENSbus.
2. If
step 1 doesn’t resolve
issue, a
failed display board is likely,

AC fail, battery
voltage good
1. Proper AC
voltages or frequency
not applied
2. Charger failure
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. Correct
charger AC input voltage as
required
2. If step 1 doesn’t r
esolve issue, a
charger failure is the likely cause.
Replace charger.

AC fail, high
battery voltage
1. Proper AC voltages
or frequency not
applied
2. Charger failure
And
3. Alarm setpoint
incorrect for

4. DC voltage is high
due to an external
source such as an
alternator

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 reso
lve
RED AC light, a charger failure is
the likely cause. Replace charger.
