8.6.4 Alarms
The Alarm warning light (Fig. 134,3) flashes if set limit values are exceeded
or fallen below.
The Alarm warning light (Fig. 134,3) flashes if the battery voltage falls below
11 V. If the 12 V power supply is switched on, the relevant battery symbol
(Fig. 134,6 or 9) also lights up and "11.0" starts flashing on the indicator
scale for battery voltage (Fig. 134,1). Danger of total discharge.
Total discharge damages the battery.
If the voltage of the batteries falls below 10.5 V, the battery monitor in
the transformer/rectifier switches off all the 12 V appliances.
When the battery alarm comes on, switch off all appliances and charge
the battery, either by mobile operation or by connection to a 230 V
power supply.
The Alarm warning light (Fig. 134,3) starts to flash and the corresponding
tank symbol (Fig. 134,7 or 8) lights up as soon as the water tank is empty or
the waste water tank is full.
Fill water tank or empty waste water tank.
If the vehicle is connected to the 230 V power supply, the 230 V indica-
tor lamp is lit even if the 12 V power supply is switched off via the rotary
knob.
The 230 V indicator lamp (Fig. 134,10) illuminates whenever line voltage is
available at the transformer/rectifier input.
