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 vehicle's engine is running
and the alternator supplies sufficient 12 V operating power.
Gas operation
If the 240 V power supply is not connected and the vehicle's engine 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. In the case of a fault in gas operation the text "GAS" flashes in the oper-
ating indicator (Fig. 195,4).
Change-over between
energy sources
When changing over between the different power sources there are forced
delays built in the AES. This means, that after a change-over to a new energy
source the refrigerator can not be operated immediately. When changing over
from 12 V operation to gas operation, a 15-minute delay is built in the AES.
This prevents a change-over to gas operation when the vehicle is stopped
briefly and the engine is switched off (e.g. stop to fill tank).
Refrigerating temperature
control
When turned on the first time the refrigerator automatically selects the middle
thermostat position. This position can be adjusted manually by using the
switch for temperature setting (Fig. 195,6). The indicator LEDs (Fig. 195,5)
show the selected thermostat position. The refrigerating temperature for the
three types of energy is set with the switch. It takes a few hours till the refrig-
erator reaches its normal operating temperature. When changing over the
operating mode the thermostat setting will be maintained. The refrigerating
temperature is retained regardless of the type of power being used.
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.
Never let gas escape unburned due to danger of explosion.
Open the regulator tap on the gas bottle and the gas isolator tap "Refriger-
ator".
Open flames are prohibited at petrol stations. If the stop takes longer
than 15 minutes, the refrigerator has to be turned off at the energy
selector switch.
