4. Use the mode selector switch to select the “Auto” function,
or one of the power sources that you want. The LCD

POWERING WITH ELECTRICITY
Auto Mode
Mains voltage (230V)
This energy source will be selected if the mains voltage is
greater than 200V. This power supply requires a continuous
current of 12V to operate the electronic control system.
Direct Current (12V)
The SES system will select 12V powering only if a mains
voltage (230V) is unavailable, the vehicle engine is running
and a voltage higher than 11V is available. If a fault occurs
during electrical powering (230V or 12V), an error message
will not be shown on the display as long as another energy
source is available. The system will automatically switch to
the available energy source that has the highest priority.
Selecting Manually
Mains voltage (230V)
The LED on the main switch warns you whenever insufficient
voltage is available or if a fault occurs. If this happens, the
LED will change from green to red and flash once per
second and an error code is shown on the LCD display.
When sufficient current is available again, or the fault has
been resolved, the main switch LED will emit a steady
green light.
Direct current (12V)
The main switch LED warns you whenever your vehicle’s
engine is not running, or if a fault occurs, or in insufficient
voltage is available. If this happens, the LED will change from
green to red and flash once per second and an error code is
shown on the LCD display. Once the engine is running, or
the fault has been resolved, or sufficient voltage is available
again, the main switch will again emit a steady green light.
NB if the refrigerator has been manually set to operate at
12V, it will not automatically switch to another energy
source when your vehicle’s engine is not running. In this
case the refrigerator will stop cooling.
