OLYHAn AES/compressor refrigerator is powered by the living area battery
when the vehicle engine is switched off.
Mains charging of starter
battery This feature provides an automatic float charge for the starter battery at up to 8 A if the 230 V mains is connected to the Electrobloc.
Awning light relay This relay controls the power supply of the awning light. The power supply to
the awning light is automatically interrupted as soon as the engine is running
and the D+ connection is live. The awning light can also be used if the 12 V
power supply is switched off.
Tank heater relay This relay controls the waste water tank heater. The waste water tank heater
is activated at the control and switch panel.
6.3 Battery monitor
Automatic disconnector The battery monitor of the control and switch panel compares the voltage of
the living area battery to a reference voltage. As soon as the battery voltage
falls below 10.5 V, all 12 V consumers are switched off via main switch relays
1 and 2. Only the frost protection valve is still powered. The automatic discon-
nector is not triggered by short-term low voltage (less than 2 seconds),
caused by high current when switching on consumers.
If an overload or an insufficiently charged living area battery causes the volt-
age to fall so low that the automatic disconnector is triggered, any consumers
which are not essential should be switched off.
You may be able to switch on the 12 V power supply for a short time. To do
this, switch on the 12 V main switch on the control and switch panel.
However, if the battery voltage remains below 11.0 V, you cannot switch the
12 V power supply back on.
Fully charge up the living area battery as soon as possible.
7 Maintenance
The Electrobloc requires no maintenance.
Cleaning Clean the Electrobloc with a soft, slightly damp cloth and mild detergent.
Never use spirit, thinners or similar substances.
Do not allow fluid to penetrate the inside of the Electrobloc.

ing area battery. The separation of the batteries is activated with the control
and switch panel.
Switch off the system if you are not going to use the motorhome for a lengthy
period (for example during the winter).
Shutting down the system
for up to 6 months Fully charge up the living area battery before shutting down the system. The living area battery is then protected against total discharge. This applies only
if the battery is intact. Follow the instructions of the battery manufacturer. The
shut down system requires approx. 4 Ah a month.
