V/tank gauge for battery voltage and water or waste water
levels
Battery voltage
The V/tank gauge is for the indication of the battery voltage of the starter bat-
tery or the living area battery.
With the V/tank gauge (Fig. 117,2), note the top scale. The gauge automati-
cally lights up as soon as a switch is pressed.
Displays:
Press switch (Fig. 117,11) "
": The battery voltage of the starter battery
is displayed.
Press switch (Fig. 117,10) "
": The battery voltage of the living area bat-
tery is displayed.
The following tables will help you correctly interpret the battery voltage of the
living area battery displayed on the panel IT 96.
Z
When leaving the vehicle, switch off the main 12 V power supply at the
panel. This prevents any unnecessary discharge of the living area battery.
Z
Appliances, such as control units (e.g. solar charge regulator, defroster or
panel) or fitted appliances (e.g. heating, refrigerator or step) continue to
take power from the battery capacity, even if the 12 V power supply on the
panel is switched off. Therefore disconnect the living area battery from the
12 V power supply via the switch on the transformer/rectifier if the vehicle
will not be used for a long period of time.
