5.5 Checking the battery voltage
Battery voltages are indicated on the
to 14.7 V. The illuminated scale points indicate the critical zone in red, the
normal range is green.
„
Press the left side of the battery switch three times briefly:
The living area battery voltage is indicated in volts on the "V" scale.
„
Press the right side of the battery switch once briefly:
The starter battery voltage is indicated in volts on the "V" scale.
In mobile operation, the voltage of the starter battery is indicated slightly too
low if the refrigerator is on with 12 V. If the refrigerator is switched off or oper-
ated using gas, the indicated voltage is correct. If the engine is switched off,
the voltage of the starter battery is also indicated correctly.
The following table will help you correctly interpret the living area battery volt-
ages displayed by the control and switch panel. These values only apply to
lead gel batteries in use, not to off-load voltage.
Battery voltage
Less than 10.5 V
11 V or more
10.5 V to 12 V
12 V to 13.2 V
More than 13.2 V
13.8 V constant

W
If the living area battery is totally discharged or overcharged for a lengthy
period, it will be irreparably damaged.
W
If the 12 V power supply is overloaded, switch off some of the consumers.
W
Inactive consumers can gradually discharge the battery.

Description
P Risk of total discharge
P The battery monitor switches off all
consumers (apart from the frost
protection valve)
The 12 V power supply can be switched
on using the main switch
P If the voltage falls below 12 V, the
battery alarm is triggered
P Warning lamp "CHARGE !" flashes
P If the voltage remains under
1)
11-12 V for more than 1 minute, the
battery capacity is set to "zero"
P If the voltage remains under

11-12 V for more than 5 minutes,
the system is switched off
Battery off load
Battery is being charged: Main charge
