BATTERY CHARGER - If ERROR LED comes on, see ERROR CAUSES section.
PROBLEM INDICATION SOLUTION
AC IN GOOD LED is flashing, but will
not start charging
(allow 40 seconds to synchronize)
Check for the correct AC voltage or
frequency at the AC input terminal.
AC frequency at the AC input terminal
is out-of- tolerance (too high or low) or
AC voltage outside ‘Upper/Lower VAC
limit’ settings If AC source is a generator, adjust AC
voltage or frequency accordingly.
Charger drops off before full
charging has finished. (No ERROR
comes on)
Check for the correct AC voltage or
frequency using the Control Panel.
AC frequency at the AC input terminal
drops out-of- tolerance (too high or low)
or AC voltage falls outside
‘Upper/Lower VAC limit’ settings. If AC source is generator, adjust AC
voltage/frequency accordingly.
Reduce your ‘Set AC Amps’ setting to
limit the pull on the AC source.
Open the ‘Upper/Lower VAC limit’
settings “window” to allow
synchronization.
Circuit breaker on inverter is open Engage circuit breaker on side of unit
(press hard on breaker button to ensure
it is engaged)
Ambient temperature may be high
causing unit to overheat and ramp down
the charging. Cool the unit down or check the inverter
cooling fan, or check for anything
preventing air flow
Charger drops off before full
charging (or equalization) has
finished
ERROR LED flashes and AC output
drops momentarily.
Cold temperature around batteries with
BTS (Battery Temperature Sensor)
installed may be causing unit to reach
HIGH BATTERY CUTOUT setting Disconnect BTS during charging or
increase HIGH BATTERY CUTOUT
setting.
Charger drops off before full
charging has finished.
(ERROR comes on)
See ERROR CAUSES section
Charger output is low Loose or corroded battery connections Check and clean all connections
Loose AC input connections Check all AC wiring connections
Weak/soft batteries Replace batteries
Battery cables too small or too long Refer to cable and battery
recommendations in owner’s manual
Batteries being charged above the
Bulk/Float setting NOTE: To bring batteries that are cold to the correct state of charge may require
charging at a higher voltage. Remove the BTS and determine if your voltage returns
to the bulk/float voltage
Temperature probe is installed Refer to the 'Battery TempComp volts
DC' reading while charging. (a) Ensure that the temperature probe
is not in a cold area or has not fallen off
the batteries.
(b) Ensure that there is no other DC
charging source on the batteries
Temperature probe is not installed Refer to the ''Battery actual volts DC'
reading while charging. Ensure that there is no other DC
charging source on the batteries
LBX mode is enabled, but you do not
want the unit to go into Float mode
(Float LED is ON)
Ensure your 'Set Low Battery Cut In
VDC' setting is lower than the 'Set Bulk
volts DC'' setting Low Battery Cut In voltage is set to high
to prevent the charger from going into
the float charge
