Manually calibrating the sensor
The system can be calibrated manually if no electrical devices
have been switched on in 12V operation. Opening the battery
circuit breaker switches off the electronics in the superstruc
-
ture (see item: battery circuit breaker). Now the sensor can
calibrate itself. This process takes approx. three hours. If the
battery circuit breaker is then switched on again, a value of “1”
should be shown on the display.
Charger (charging the battery)
Battery is charged when the charger is con-
nected to the 230V mains. The integrated fan
is activated.
Battery is charged via the generator. Motor has
been started. Battery charger is not activated.
During calibration, the vehicle must not be hooked up to
the 230V mains (the charger must not charge the battery
during calibration). Furthermore, the vehicle must not be
started while the sensor for the starter battery is being
calibrated.
Battery is charged when the charger is con-
nected to the 230V mains. The integrated fan
is deactivated.
