Operation
6.4
Using the battery monitor
The cooling device is equipped with a multi-level battery monitor that protects
your vehicle battery against excessive discharging when the cooling device is
connected to the DC power supply.
If the cooling device is operated when the vehicle ignition is switched off, the
cooling device switches off automatically as soon as the supply voltage falls
below a set level. The cooling device will switch back on once the vehicle
battery has been recharged to the restart voltage level.
A
NOTICE! Damage hazard
When switched off by the battery monitor, the vehicle battery will
no longer be fully charged. Avoid starting repeatedly or operating
current consumers without longer charging phases. Ensure that the
vehicle 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
Proceed as follows to select the battery monitor mode:
1. Switch on the cooling device.
2. Press the "SET" button three times.
3. Use the "+" and "–" buttons to select the battery monitor mode.
✔ The selected mode then appears in the display for a few seconds. The dis-
play flashes several times before it returns to the current temperature.
I
NOTE
When the cooling device is supplied by the vehicle battery, select
the battery monitor mode "HIGH". If the cooling device is con-
nected to a supply battery, the battery monitor mode "LOW" will
suffice.
