FIG. 1
This refrigerator is equipped with an Automatic Energy
Selector (AES) which controls its operation and energy
supply.
The system selects the available energy source in the
order:
230-240 V - 12 V - LP gas
No manual operation is necessary for selecting the
energy source.
The control panel is shown in fig.1.
The refrigerator is set into operation by pushing button
(A) (main switch). The AES LED (C) lights green show-
ing: AES system working. Push- button (B) is used for
setting the electronic thermostat. The thermostat LEDs
(D) shows the chosen temperature position. When there
is a demand for refrigeration, AES will connect the most
favourable of the available energy sources.
Note: 12 V must always be available to supply the
electronics.
STARTING THE REFRIGERATOR
All references are to fig. 1.
LP Gas operation
AES will select LP gas operation under the following
conditions:
•
No AC (230-240 V) available
•
Engine not running (no high current at 12 V DC
available)
•
AC available but too low
•
Engine running but DC supply too low
(condition three and four are briefly described in
item Undervoltage operation)
When the system chooses LP Gas operation, the flame
failure device is automatically opened, allowing the gas
to flow to the burner. At the same time, the electronic
igniter is energized.
After initial installation, servicing, or changing gas cylin-
ders etc., the gas pipes may contain some air that should
B
D
be allowed to escape by briefly turning on the refrigerator
or other appliances. This will ensure that the flame lights
immediately.
If the flame goes out (by gust of wind etc.), the igniter is
immediately activated and reignites the gas.
Note: The control electronics and the igniter must have
12 V DC supply to operate.
Gas trouble-shooting
If the AES LED (C) is flashing red, the system was not
able to start or continue gas operation. Set the switch
(A) to "OFF" and check that there is enough gas in the
gas bottle, that its valve is open and that any valves in
the gas line to the refrigerator are open.
Then push button (A) to "ON" again. After 10 sec. AES
will repeat the ignition sequence. When the AES LED
(C) again starts flashing red after 30 sec., the trouble
persists (air in the line, no gas?). Switch (A) briefly off
and then on again. It might be necessary to repeat this
operation 2-3 times if the tubing contains air (after
changing gas bottles, repairs etc.).
If this does not help, you should consult a service
technician.
230-240 V Operation
When a mains connection is available, AES will select
this. Please note, that even being in AC mode, 12 V DC
is necessary for the internal supply of the electronics.
12 V Operation
AES will select the 12 V mode of operation only when
the vehicle engine is running (detected by the alternator
connection of the fridge D+).
SWITCHING BETWEEN ENERGY
SOURCES
When switching from one energy source to another,
there are some delays implemented in the AES system.
The 15 min. delay between switching off the engine and
starting gas mode is intended to delay the starting of gas
mode e.g. when stopping at a filling station.
WARNING: It is not allowed to have a naked
flame at a gas filling station. If you are not sure,
that your stop is shorter than 15 min., you are
advised to switch off the main switch (A), fig. 1,
when stopping at a filling station.
Undervoltage operation
The AES system is designed to guarantee the maximum
cooling efficiency under any circumstances. Therefore,
the system monitors continuously the voltage level while
being in either 12 V DC or 230-240 V AC mode. If the
voltage is too low, the system switches to Gas mode
shown by the yellow LED (E in fig. 1.). The system stays
in Gas mode, until the electrical supply voltage has
recovered to normal level.
REGULATING THE TEMPERATURE
The position number refers to fig.1.
It will take a few hours for the refrigerator to reach normal
operating temperature. So we suggest you start it well
in advance of a trip and if possible store it with precooled
