Devices that set off during operation show that there is a
defect; they must be checked and/or repaired by an electrical
engineering specialist.
Switching it back on again and again will do no good. The
automatic circuit breaker also goes off when the rocker
switch is held firmly in place.
Operation when the motor is running
As soon as the motor is running, a relay connects the starter
battery and the van battery in parallel. Therefore, the dynamo
charges both batteries. If the vehicle engine is issued, both bat
-
teries are disconnected from each other again. In this way, the
starter battery cannot be discharged by equipment in the van.
The absorber refrigerator* can only be operated on 12V when
the vehicle is driving. When the engine is not running, 12V
operation of the refrigerator will automatically be switched off.
Always turn the motor off before hooking up the 230V
mains connection via the CEE external socket.
- If the automatic circuit breaker goes off abruptly again, there is
either a short circuit or an earth fault.
To optimally charge a discharged modular battery while
driving, as many 12V electrical devices as possible should
be switched off.
Checklist
• Turn off the motor.
• Switch on the 12 V master switch.
• Turn off all equipment that uses 12 V.
• Start the motor.
The voltage of the van battery must rise if
- the engine speed is above the idling speed,
- the vehicle‘s battery is not completely discharged.
The control panel shows whether or not the generator has
been charged. If this is not the case, please check the following:
• Is the 50A fuse in the supply line to the ancillary battery
near the motor battery functioning properly?
• Is the “Motor running” signal on the input module on?
