Status Indicators
MAINS
- This light will be illuminated when 240V AC mains power is applied.
In this mode, the refrigerator will operate at high-speed.
RUN
-
This indicator will be illuminated whenever the refrigerator compressor is
running. (either on mains or battery power)
FAULT ID.
- This indicator is used to identify common faults. The light will flash a
sequence of pulses and then pause before repeating the code.
Refer to the Troubleshooting section Pg 8 for more details.
REVERSE POLARITY
- This indicator identifies that the power applied to the 12V input has the
incorrect polarity. Check all wiring connections for correct polarity.
POWER PACK OVER-TEMPERATURE
- In the event that the fridge electronics overheat, a
cooling fan will be activated. If the fan cooling is insufficient to correct the error, the refrigerators'
compressor will automatically slow-down (over-temperature light will flash).
If temperatures continue to increase, the refrigerator will be shut-down as a protection feature
(over-temperature light will be permanently illuminated)
This error is self-correcting and normal operation will resume when electronic temperatures
return to normal.
The National Luna Weekender is equipped with status indicators which show the
operation of the refrigerator and help to identify faults that may occur.
A brief description of the status indicators is shown below :

Fault description
2 Fan over-current cut-out. There is a problem with the ventilation fan.
3 Motor start error. The rotor is blocked or the system pressure is too high.
4 Minimum speed error. The motor cannot maintain a minimum speed of 1900 rpm.
5 Thermal cut-out. The electronic circuitry has over-heated.
1 Low voltage. Battery is flat, there is poor wiring or poor connections.
# of
flashes
Fault description
wiring losses are too high or there is a poor connection to the power source.
2 Fan over-current cut-out. There is a problem with the ventilation fan. It is possible that
the ventilation fan is obstructed, blocked or damaged.
3 Motor start error. The compressor has not started successfully. This can happen in extreme
environments where the refrigerator is heavily loaded and temperature is very high.
4 Minimum speed error. The motor cannot maintain a minimum speed of 1900 rpm. This can
be the result of an internal electronics failure.
5 Thermal cut-out. The electronic circuitry has over-heated. This can occur in very hot
environments. The electronics will reset when the temperature has dropped.
1 Low voltage. This is shown when the supply voltage is low. The battery could be flat,
