Excessive compressor cycling protection
The system has been turning on and off too frequently.
Take spare cassette in case refrigeration system fault.
• Condenser blocked
• Poor installation or ventilation
• Cabinet or cassette gasket seals leaking
• Door not self-closing or gasket leaking
• Product hot or blocking the cabinet’s airflow
• Overloaded from excess door openings/ambient
• Fan motor or blade (condenser or evaporator)
• Controller
• Compressor or gas leak = SWAP cassette

Description Possible root cause
Table 7: Alarms
Code Description Possible root cause
8Estimated product temperature below allowable range
The estimated product temperature has been below the allowable
range for longer than the permissible time. Potential causes are: an
empty or partially filled cabinet, or low ambient temperature.
• Low ambient
• App settings
• Controller
9Estimated product temperature above allowable range
The estimated product temperature has been above the allowable
range for longer than the permissible time. Potential causes are:
excessive door openings, door being left open, or warm product
loaded into cabinet.
NO Swap cassette required to be taken (but may be required as
fault could still be with sealed refrigeration system).
• Condenser blocked
• Poor installation or ventilation
• Frozen blocked evaporator coil
• Cassette gasket leaking (to cabinet seal or lid seal)
• Door leaking air (bad gasket or door not self-closing)
• Product hot or blocking the cabinet’s airflow
• Overloaded from excess door openings/ambient
• Fan motor or blade (condenser or evaporator)
• App settings
• Controller
• Compressor or gas leak = arrange SWAP cassette
15 Excessive condensing temperature protection
The system was operating at an excessive temperature and has shut
down to prevent permanent damage. This alarm may occur due to
very high ambient temperature.
NO swap cassette required
• Condenser not clean
• Poor installation or ventilation
• Condenser fan motor or blade
• Controller
17 Control probe failure
A critical system sensor has failed and the cabinet can no longer
operate.
NO swap cassette required
• Control probe or circuit
• Controller
18 Electrical over-current protection activated
The compressor was drawing too much current and has shut down to
prevent permanent damage.
Take a spare cassette in case refrigeration system fault.
• Condenser blocked
• Poor installation or ventilation
• Cabinet or cassette gasket seals leaking
• Door not self-closing or the gasket is leaking
• Product hot or blocking the cabinet’s airflow
• Overloaded from excess door openings/ambient
• Fan motor or blade (condenser or evaporator)
• Controller
• Compressor or gas leak = SWAP cassette
19 Failed to reach set temperature
The refrigeration system has been operating continuously for a long
period without reaching the set temperature.
Take a spare cassette in case refrigeration system fault.
• Condenser blocked
• Poor installation or ventilation
• Frozen blocked evaporator coil
• Cabinet, door or cassette seal leaking
• Product hot or blocking the cabinet’s airflow
• Overloaded from excess door openings/ambient
• Fan motor or blade (condenser or evaporator)
• Controller
• Compressor or gas leak = SWAP cassette
20 Over cooling product
The internal temperature is too low. The system has temporarily shut
down until the temperature has returned to normal. This can occur if
the set temperature has been raised by a large amount.
Confirm if really too cold; change parameters accordingly.
