Using the battery monitor
NOTICE! Danger of damage!
A
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.
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.
NOTE
I
When switched off by the battery monitor due to low voltage the dis-
play (fig. 2 5, page 3) goes blank and the "POWER" LED
(fig. 2 2, page 3) flashes orange.
In "HIGH" mode, the battery monitor responds faster than at the levels "LOW"
and "MED" (see the following table).
Battery monitor mode
Switch-off voltage at 12 V
Restart voltage at 12 V
Switch-off voltage at 24 V
Restart voltage at 24 V
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.
