Using The Battery Monitor - Dometic CFF12 Instrucciones De Uso

Operation
The coolers have an integrated multi-voltage power supply with priority circuit for
connecting to an AC voltage source. The priority circuit automatically switches the
cooler to AC operation if the device is connected to an AC power supply, even if the
DC connection cable is still attached.
When switching between the AC power supply and the battery supply, the red LED
may light up briefly.
1. Plug the AC connection cable (fig. 1 3, page 3) into the AC voltage socket of
the cooler (fig. 4 1,page 5).
2. Connect the connection cable to an AC power outlet.

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
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.
A
NOTICE! Damage hazard
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
The battery monitor mode can be selected as follows:
1. Switch on the cooler.
2. Press the "SET" button (fig. 3 5, page 5):
– CFF12, CFF20, CFF35, CFF45: Three times.
– CFF70DZ: Four times.
