Second, the control system incorporates a low
battery protection circuitry that will prevent a
total lack of cooling due to a gradual loss of 12
volts DC to the refrigerator’s terminal block. If
the battery voltage to the terminal block drops
to approximately 9.5 volts DC and the
refrigerator is operating on 120 volts or LP
gas, the system will electronically bypass the
thermostat and the refrigerator will operate
continuously on LP gas until the low voltage
condition is corrected.

As a warning of this condition the L.E.D. lamp
assembly will shut off during the voltage drop.
When the battery voltage returns to an
acceptable level the green L.E.D. lamp will
turn on and the refrigerator will again operate
on its predetermined priority system.
