10.6.4 Operation (Dometic 7 series with AES)
Operating modes The refrigerator is equipped with an automatic system to select the type of
power (AES). The AES automatically selects the optimal energy source and
regulates the refrigerator operation. Manual intervention to select the type of
power is possible but not required.
The AES selects from the following types of power:
Solar installation 12 V
240 V AC
12 V DC
Gas
Choosing the available energy source highest on the list.
240 V operation If the 240 V power supply is connected, this energy source is selected as the
first priority by the AES.
12 V operation 12 V operation is only selected by the AES if the engine of the towing vehicle
is running and the alternator supplies sufficient 12 V operating power.
Gas operation
If the 240 V power supply is not connected and the engine of the towing
vehicle is not running the AES selects the gas supply. When selecting gas
operation the ignition fuse is opened automatically so gas can get into the
burner. At the same time the electronic ignition is activated. If the gas flame is
extinguished, e.g. by blast of wind, the ignition is activated immediately and re-
ignites the gas. When the gas operation is faulty, the "GAS" indicator lamp
(Fig. 157,2) flashes red.
Even when the 12 V power supply is switched off, a small electrical power
flows which puts an extra load on the living area battery. Always switch off
the refrigerator for a temporary lay-up.
