Battery Sensor
An Intelligent Battery Sensor (IBS) has been connected to the battery
terminal. It monitors the actual current and the actual voltage in a
highly precise manner. Please refer to Chapter 7.3 to calibrate the
sensor.
It is possible to precisely predetermine the operating time of the
battery based on the actual consumption. The IBS ensures that the
battery will be charged in good time and assists in providing active
energy management so that the performance requirements of the
different electrical devices can be coordinated with the charging of
the battery.
The charge state of the battery, age or remaining time until it is too
low to operate are all shown on the TFT display of the control panel.
Charging is carried out gently in accordance with the steady-state
principle by an "intelligent" charger.
Pushbutton
j
A pushbutton is located directly on the battery container. It is
used to disconnect the battery from the 12 V electrical system. At
the same time, this button serves as a 30 A automatic circuit breaker.
If the caravan is not used for a long period of time, please disconnect
the battery from the electrical system in order to prevent the battery
from being excessively discharged.
• Always charge the ancillary battery for at least 10
hours before each journey, directly after each jour-
ney and before you take the caravan temporarily
out of service:
- Before each journey, please check that the battery
is charged (see p. 71). If necessary, connect it to
the mains and press the main switch to start char-
ging the battery.
- The battery is only charged if it's voltage has drop-
ped to 8V.
- Use every opportunity during your journey to char-
ge the battery.
- Leave the main switch on whenever the caravan is
being used so that the battery is charged regularly.
• Do not forget to activate the pushbutton on the
battery container.
• If the caravan is not in use for a long period of
time, the battery should be disconnected after it
has been fully charged by pressing the pushbutton
on the 12V electrical system.
• The battery loses its effectiveness after having
been used for a while and at low temperatures.
- A warning will go off if the battery charge is less
than 50% of its nominal capacity.
- The battery sensor is safeguarded by means of a
10 A fuse.
