Activating battery
disconnection
(transformer/rectifier
without battery cut-off
switch):
Switch off 12 V power supply.
Press button for living area battery (Fig. 138,14) and hold it down for
approx. 10 seconds. The "V" volt (Fig. 138,2) and "A" ampere (Fig. 138,3)
symbols flash three times. The living area battery is disconnected from the
12 V power supply.
Deactivating battery
disconnection
(transformer/rectifier
without battery cut-off
switch):
Press the "12 V" button (Fig. 138,18) and hold it down for approx.
5 seconds. The "V" volt symbol (Fig. 138,2) flashes three times. The living
area battery is connected to the 12 V power supply. The indicator lights up
after approx. 2 seconds.
9.9.3 Batteries gauge
The voltage and charging/discharging of the living area battery or the starter
battery voltage can be indicated using the batteries gauge.
Displays:
Press button for living area battery " " (Fig. 138,14). The "V" volt symbol
(Fig. 138,2) lights up. Depending on whether the battery is being charged
or discharged, the "A" ampere symbol lights up white or red respectively.
The battery voltage and current of the living area battery are displayed
using the LEDs in the gauge.
Press button for starter battery " " (Fig. 138,15). The "V" volt symbol
(Fig. 138,2) lights up. The battery voltage of the starter battery is displayed
using the LEDs in the gauge.
The tables below will help you interpret the statuses displayed on the panel.
When leaving the vehicle, switch off the 12 V main switch. This prevents
any unnecessary discharge of the living area battery.
Appliances such as the safety/drainage valve, charger, solar charge regu-
lator and panel consume approx. 20 mA to 65 mA of electricity from the
battery capacity, even when the 12 V main switch is turned off. Therefore
disconnect the living area battery from the 12 V power supply, if the vehicle
will not be used for a long period of time.
