“AUTO”-operation

RM7XX5 L - models are equipped with an “AUTO”-MATIC function.

Explanations:

Upon switching on, the electronics automatically select one of the three

possible energy types: 230V - 12V - liquid gas. The control electronics

automatically ensure that the refrigerator is supplied with the optimum

source of energy in each respective case.

Priority 1.) Solar (12V DC)

2.) 230V AC

3.) 12V DC

4.) Liquid gas

The selected energy is displayed by the corresponding LED (i.e. 230V)

230 V - operation

If sufficient supply voltage is available (more than 200V), this power source is

selected as the first option ( no solar-system installed).

12 V - operation

12V operation should only be selected while the vehicle motor is running or there

is sufficient voltage available from the solar system. This can be detected from

the D+ connection of the alternator to the electronics, or from the respective sig-

nal on the solar charge regulator.

Gas operation

Gas operation is selected in the following circumstances:

 No supply voltage available.

 The vehicle engine is not running.

 Supply voltage less than 200V

Gasfaults at “AUTO” - mode see “5.2.4”

REFUELLING STOP

In order to prevent unintended switching to gas operation during refuelling,

the electronic system starts gas operation of the refrigerator, after the

motor has been turned off for 15 mins. During this time the appliance is in

stand-by operation mode and only the "AUTO" LED lights up.

The use of naked flames is prohibited in petrol station environments.

If the refuelling stop lasts longer than 15 mins., the refrigerator should be

switched off at the main switch (A), or switched over to another energy type.

Set energy selection switch (A) to position

“AUTO” .

The LED "AUTO" illuminates.

Manual operation is possible at any time.
