Problem
The charger is not
functioning
The battery is not
being charged fully
The battery is
overcharged
Battery charge
current drops to 0
when the
absorption voltage
is reached
22
Cause
The AC input voltage or
frequency is out of range
The thermal circuit breaker has
tripped
Incorrect charging current
A defective battery connection
The absorption voltage has been
set to an incorrect value
The float voltage has been set to
an incorrect value
The internal DC fuse is defective Inverter is damaged
The absorption voltage has been
set to an incorrect value
The float voltage has been set to
an incorrect value
A defective battery
The battery is too small
The battery is too hot
Alt. 1: Battery overtemperature
(> 50°C)
Alt 2: Battery temperature sensor
faulty
Solution
Ensure that the input voltage is
between 185Vac and 265Vac, and
that the frequency matches the
setting
Reset the 16A thermal circuit
breaker.
Set the charging current at
between 0.1 and 0.2x battery
capacity
Check the battery terminals
Adjust the absorption voltage to
the correct value
Adjust the float voltage to the
correct value
Adjust the absorption voltage to
the correct value
Adjust the float voltage to the
correct value
Replace the battery
Reduce the charging current or
use a battery with a higher
capacity
Connect a temperature sensor
- Allow battery to cool down
- Place battery in a cool
environment
- Check for shorted cells
Unplug battery temperature sensor
from the MultiPlus.
Reset the MultiPlus by switching it
off, then wait for 4 seconds and
switch it on again
If the MultiPlus now charges
normally, the battery temperature
sensor is faulty and needs to be
replaced
