B. Automatic Energy Selection (only with RM 7XX5 L)
5.2.5“AUTO”-operation
RM7XX5 L - models are equipped with an
Set energy selection switch (A) to position “AUTO” .
The LED "AUTO" illuminates.
Manual operation is possible at any time.
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
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
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.
