Using The Battery Monitor - ARB ELEMENTS Bedienungs- Und Serviceanleitung

6.12 Using the battery monitor

Your ARB Fridge is fitted with a battery monitor to control the level of discharge of your
battery. The battery monitor has three settings; HIGH, MEDIUM and LOW. When set to
HIGH, the battery monitor will provide maximum protection for the battery against
excessive discharging. When set to LOW, the battery monitor will allow maximum use
of the energy stored in the battery. Table 1 shows the voltage cutout levels for the three
battery monitor settings.
If your fridge can operate without the vehicle ignition being on, the battery monitor will
cause the unit to switch off as soon as the supply voltage falls below the set level. The
fridge will automatically restart once the restart voltage is reached.
NOTE - When the battery monitor is active, the cooling unit (including
compressor) will not run. The power LED on the control panel will be OFF
and the check LED will flash RED. The cooling unit will not restart until the
voltage level of the battery reaches the restart voltage listed in Table 1.
Switch off voltage – 12V DC
Restart voltage – 12V DC
Switch off voltage – 24V DC
Restart voltage – 24V DC
If your fridge is connected to the starting battery on a 12/24V DC system, ARB
recommends that the battery monitor level be set to HIGH/MEDIUM.
If your fridge is connected to an auxiliary battery on a 12/24V DC system, ARB
recommends that the battery monitor level be set to LOW.
NOTE - ARB recommends that the battery be charged once the battery
monitor has been triggered. ARB also recommends that all non-essential
electrical equipment that draws power from the same source as the fridge be
turned off until the battery is fully charged.
