Operation
After connecting the battery, charging starts automatically and
the ‘ON’ LED shall light up to indicate this.
The VETUS battery charger has a charging type that can be
denoted as IUoU-float.
BOOST-PHASE
The battery charger begins to charge the battery with the maxi-
mum charging current.
As soon as the gas pressure of the battery is reached (See ‘7
Technical details’, charge voltage, Boost), the charge voltage
shall not further increase and the current will gradually
decrease.
FLOAT-PHASE
If the charging current has decreased to approx. 10% of the
maximum
charging current, the charging voltage will be decreased to the
Float Voltage (see ‘7 Technical details’, charging current, Float).
This reduces the water usage of the batteries.
5.1
Protection
The battery charger switches itself off at the following malfunc-
tions and switches itself on again once the malfunction is
resolved:
-
Mains voltage too low
- Short circuiting of the output
-
Battery voltage too high
-
Battery charger at too high a temperature
By wrongly connecting plus and minus of the battery the charg-
ing current fuse will blow.

LED indicators
The battery charger BC120202 is provided with the following
LED indicators:
The battery charger BC120403/ BC240303 is provided with the
following LED indicators:
The battery charger BC120263/ BC120603/ BC120803/
BC240503/ BC240803 is provided with the following LED indi-
cators:
80 A - 40 A (BC240803) selector switch
The BC240803 battery charger has an 80 A - 40 A selector
switch, with which the maximum charging current of the charg-
er can be set.
By reducing the maximum charging current the amount of
power consumed is simultaneously lowered. A shore power
connection with an otherwise too low fuse can then be used to
charge the batteries.
