ALARM MESSAGE
RTC
CABINET PROBE
EVAPORATOR PROBE
CONDENSER PROBE
NEEDLE PROBE
THERMAL SWITCH
HIGH PRESSURE
LOW PRESSURE
Clock error
To correct: Re-set the date and time.
Main results: The device will not save the date and time an HACCP alarm
occurred. The alarm output will be activated.
Cabinet probe error
To correct: Check the integrity of the probe. Check the device-probe connection.
Check the cabinet temperature.
Main results: If the error occurs during "stand-by", it will not be possible to start
up an operating cycle. If the error occurs during blast chilling or blast freezing,
the cycle will continue with the compressor in continuous mode. The maximum
temperature alarm will never be activated. The door heaters will never be
switched on. The alarm output will be activated.
Evaporator probe error
To correct: The same as for the cabinet probe error but with reference to the
evaporator probe.
Main results: the alarm output will be activated.
Condenser probe error
To correct: The same as for the cabinet probe error but with reference to the
condenser probe.
Main results: The condenser fan will operate in parallel with the compressor.
The condenser overheat alarm will never be activated. The compressor locked
alarm will never be activated. The alarm output will be activated.
Needle probe error
To correct: The same as for the cabinet probe error but with reference to the
needle probe.
Main results: If the error occurs during stand-by, the temperature controlled
cycles will be started up as time-controlled.
Thermal switch alarm
To correct: Check the condition of the multi-purpose input.
Main results: The cycle underway will be interrupted.
High pressure alarm
To correct: Check the condition of the multi-purpose input.
Main results: If the cycle underway requires the use of the compressor, the cycle
will be interrupted. The condenser fan will be switched on.
Low pressure alarm
To correct: Check the condition of the multi-purpose input.
Main results: If the cycle underway requires the use of the compressor, the cycle
will be interrupted. The condenser fan will be switched on.
