Fresh water tank
The filling level of the fresh water tank can be read off here. Press
lightly on the Alarm icon to activate the alarm (green). If the alarm
has been activated, a beep will go off when the tank is being filled.
These beeps will be sent at increasingly shorter intervals while the
tank is filling up. The filling level of the fresh water tank will be auto-
matically updated on the control panel every few seconds.
To exit from this menu, press the Back icon
one minute and the screen will automatically switch to the Start
display.
Battery management*
The current status of the auxiliary battery is displayed in the battery
menu (self-sufficient package). The charging status is shown in the
battery icon; the example shows a fully charged battery.
"U" indicates the current charging voltage, "I" the current charging
current and the remaining time until the battery is discharged is dis-
played in hours. The value "T" indicates the temperature of the bat-
U : 12,3 V
tery; this must not exceed 50° C. A warning message will be sent if
I : 5,3 A
the temperature exceeds 50° C and the battery will be shown in red
: 6,5 h
T : 0,0 °C
in the main menu on the control panel. If the battery is overheated,
R : 0
it cannot be charged. Should this warning occur repeatedly, the
camper must be taken to an authorised specialist.
The icon for the charger and the arrow towards the battery indicate
that the battery is currently being charged with the set values.
The value "R" shows the calibration check. If "1" is output, the sen-
sor will be calibrated (target state). If "0" is output, the measured
055 Ah AGM
values may deviate slightly and the sensor should be recalibrated.
Normally, calibration is carried out automatically, whereby neither
the charging nor the discharge current may be more than 150mA.
The system can be manually calibrated
- while using the 230V mains operation or
- if no electrical device has been switched on in 12V operation.
To carry this out, the battery's positive terminal (quick release clamp)
must be disconnected (see "Independent power supply"). Follow-
ing this, the sensor will be able to calibrate itself; the process will be
completed in approx. 3 hours. After the battery's positive terminal
has been reconnected the display should show Value "1".
To exit from this menu, press the Back icon
one minute and the screen will automatically switch to the Start
display.
