One alarm LED
lights and the
second flashes.
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.
Check this table for appropriate
measures in regard to this alarm
state.
The charger does
not operate.
The AC input voltage or frequency is
not within the range set.
Ensure that the AC input is between
95 VAC and 140 VAC, and that the
frequency is within the range set
(default setting 45-65Hz).
Circuit breaker or fuse in the
AC-in input is open as a result of
overload.
Remove overload or short circuit on
AC-out-1 or AC-out-2, and reset
fuse/breaker.
The battery fuse has blown.
Replace the battery fuse.
The distortion or the AC input voltage is
too large (generally generator supply).
Turn the settings WeakAC and
dynamic current limiter on.
The charger does
not operate.
“Bulk” LED flashes
and
“Mains on” LED
illuminates.
MultiPlus is in “Bulk protection” mode
thus, the maximum bulk charging time
of 10 hours is exceeded.
Such a long charging time could
indicate a system error (e.g. a battery
cell short-circuit).
Check your batteries.
NOTE:
You can reset the error mode by
switching off and back on the
MultiPlus.
The standard MultiPlus factory setting
of the “Bulk protection” mode is
switched on. The “Bulk protection”
mode can be switched off with help of
VEConfigure only.
The battery is not
completely charged.
Charging current excessively high,
causing premature absorption phase.
Set the charging current to a level
between 0.1 and 0.2 times the battery
capacity.
Poor battery connection.
Check the battery connections.
The absorption voltage has been set to
an incorrect level (too low).
Set the absorption voltage to the
correct level.
The float voltage has been set to an
incorrect level (too low).
Set the float voltage to the correct
level.
The available charging time is too short
to fully charge the battery.
Select a longer charging time or
higher charging current.
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.
Reduce the charging current or select
the ‘fixed’ charging characteristics.
The battery is
overcharged.
The absorption voltage is set to an
incorrect level (too high).
Set the absorption voltage to the
correct level.
The float voltage is set to an incorrect
level (too high).
Set the float voltage to the correct
level.
Poor battery condition.
Replace the battery.
The battery temperature is too high
(due to poor ventilation, excessively
high environmental temperature, or
excessively high charging current).
Improve ventilation, install batteries
in a cooler environment, reduce the
charging current, and connect the
temperature sensor.
The charging
current drops to 0
as soon as the
absorption phase
initiates.
The battery is over-heated (>50°C)
─ Install the battery in a cooler
environment
─ Reduce the charging current
─ Check whether one of the
battery cells has an internal
short circuit
Defective battery temperature sensor
Disconnect the temperature sensor
plug in the MultiPlus. If charging
functions correctly after
approximately 1 minute, the
temperature sensor should be
replaced.
