Operation
6.4
Using the battery monitor
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 level. The cooler will switch back on once the
battery has been recharged to the restart voltage level.
Caution – 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.
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 "UP +" (Fig. 2 6, page 3) and "DOWN -" (Fig. 2 7,
page 3) buttons to select the battery monitor mode.
✓ The selected mode then appears in the display for a few sec-
onds. The display flashes several times before it returns to the
current temperature.
Note
When the cooler is supplied by the starter battery, select the battery
monitor mode "HIGH". If the cooler is connected to a supply battery,
the battery monitor mode "LOW" will suffice.
If you wish to operate the cooler from the AC mains, set the battery
monitor to the "LOW" position.
