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 the levels
“LOW” and “MED” (see the following table).
