4.4 Low voltage protection battery monitor setting:
The cooling device is equipped with a 3-level battery monitor which protects your vehicle battery
against excessive discharging when the device is connected to the on-board DC 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.
NOTICE! Danger of Damage!
When switched off by the battery monitor, the battery will no longer be fully charged. Avoid starting
repeatedly or operating without longer charging phases. Ensure that the battery is recharged. In
“H3” level, the battery monitor responds faster than at the level
“H1”
and
“H2”
.
When the cooler is supplied by the started battery, select the battery monitor level
“H3”
, if the
cooling device is connected to a supply battery, the battery monitor level
“H1”
will suffice.
