5.12.5 Tank check unclear
If the tank level is checked in stationary operation, the red "?" warning lamp
flashes if there is a malfunction of the tank sensors. Check the sensors and
clean them if necessary.
If the tank level is checked in mobile operation, the red "?" warning lamp flash-
es. The tank level cannot be displayed accurately while driving because the
water in the tank will slosh around.
6 Starting up
The control and switch panel can only be started up with an Electrobloc and
the accessories for measuring the water tank levels.
After shutting down If the battery is separated from the system (battery separation by the control
and switch panel or a battery pole is disconnected): Check the off-load volt-
age of the battery immediately after start up. Do not connect the vehicle to the
230 V mains, do not start the engine and do not switch on any consumers
until the off-load voltage of the battery has been checked.
After an off-load time of maximum 6 months, the battery voltage should be
above 12.7 V if the battery was fully charged before shut down. If the voltage
is below 12.0 V, then the battery might be defective and need to be replaced.
Starting up the system
Press the 12 V main switch for more than 5 seconds. The 12 V indicator
lamp flashes. The system has been activated. For information on other
measures after starting up the system, see the instruction manual for the
Electrobloc.
