Using the battery monitor
A
The device is equipped with a multi-level battery monitor that protects your
vehicle battery against excessive discharging when the device is connected
to the on-board 12/24 V supply.
If the cooler is operated when the vehicle ignition is switched off, the cooler
switches off automatically as soon as the supply voltage falls below a set lev-
el. The cooler will switch back on once the battery has been recharged to the
restart voltage level.
I
In “HIGH” mode, the battery monitor responds faster than at the levels “LOW”
and “MED” (see the following table).
This is how to select the battery monitor mode:
➤
Switch on the cooler.
➤
Press the “SET” button (fig.
2
4, page 3) three times.
➤
Use the “+” (fig.
2
6, page 3) and “–” (fig.
2
7, page 3) buttons to select
the battery monitor mode.
✓
The selected mode then appears in the display for a few seconds. The
display flashes several times before it returns to the current temperature.
NOTICE! Danger of damage!
When switched off by the battery monitor, the battery will no
longer be fully charged. Avoid starting repeatedly or operating
current consumers without longer charging phases. Ensure that
the battery is recharged.
NOTE
When switched off by the battery monitor due to low voltage the
display (fig.
2
5, page 3) goes blank and the “POWER” LED
(fig.
2
2, page 3) flashes orange.
