Using Battery Monitor - ARB Fridge Freezer User Manual

6.11 Using the battery monitor
Your ARB Fridge Freezer is fitted with a battery monitor to control the level of discharge
of your battery. The battery monitor has three setting; 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 freezer 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 freezer will automatically restart once the restart voltage is reached.
NOTE - When the battery monitor is active, the cooling unit (including
compressor) w ll not run. The power LED on the control panel will be OFF i
and the error LED will flash RED. The cooling unit will not restart until the
voltage level o the battery reaches the restart voltage listed in Table 1. f
Switch off voltage – 12V DC
Restart voltage – 12V DC
Switch off voltage – 24V DC
Restart voltage – 24V DC
If your fridge freezer is connected to the starting battery on a 12/24V DC system, ARB
recommends that the battery monitor level be set to HIGH.
If your fridge freezer is connected to an auxiliary battery on a 12/24V DC system, ARB
recommends that the battery monitor level be set to LOW.
If your fridge freezer is connected to AC mains power, 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
e ectrical equipment that draws power from the same source as the fridge l
freezer be turned o until the battery is fully charged. ff
