One alarm LED
lights and the
second flashes.
The charger does
not operate.
The battery is not
completely charged.
The battery is
overcharged.
The charging
current drops to 0
as soon as the
absorption phase
initiates.

The inverter is switched off due to
alarm activation by the lighted LED.
The flashing LED indicates that the
inverter was about to switch off due
to the related alarm.
The AC input voltage or frequency is
not within the range set.
Thermal circuit breaker (TCB) in the
AC-in-1 or AC-in-2 input is open.
The battery fuse has blown.
The distortion or the AC input voltage is
too large (generally generator supply).
Charging current excessively high,
causing premature absorption phase.
Poor battery connection.
The absorption voltage has been set to
an incorrect level (too low).
The float voltage has been set to an
incorrect level (too low).
The available charging time is too short
to fully charge the battery.
The absorption time is too short. For
adaptive charging this can be caused
by an extremely high charging current
with respect to battery capacity, so that
bulk time is insufficient.
The absorption voltage is set to an
incorrect level (too high).
The float voltage is set to an incorrect
level (too high).
Poor battery condition.
The battery temperature is too high
(due to poor ventilation, excessively
high environmental temperature, or
excessively high charging current).
The battery is over-heated (>50° C)
Defective battery temperature sensor
Check this table for appropriate
measures in regard to this alarm
state.
Ensure that the AC input is between
185 VAC and 265 VAC, and that the
frequency is within the range set
(default setting 45-65Hz).
Press TCB for recovery (see appendix
A, position N and O).
Replace the battery fuse.
Turn the settings WeakAC and
dynamic current limiter on.
Set the charging current to a level
between 0.1 and 0.2 times the battery
capacity.
Check the battery connections.
Set the absorption voltage to the
correct level.
Set the float voltage to the correct
level.
Select a longer charging time or
higher charging current.
Reduce the charging current or select
the 'fixed' charging characteristics.
Set the absorption voltage to the
correct level.
Set the float voltage to the correct
level.
Replace the battery.
Improve ventilation, install batteries
in a cooler environment, reduce the
charging current, and connect the
temperature sensor.
Install the battery in a cooler
─
environment
Reduce the charging current
─
Check whether one of the
─
battery cells has an internal
short circuit
Disconnect the temperature sensor
plug in the MultiPlus. If charging
functions correctly after
approximately 1 minute, the
temperature sensor should be
replaced.
