Estimated 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.
1, 2, 3, 4
- low ambient
- App settings
- controller
9
Estimated 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.
2, 3, 4
NO Swap unit required to be taken (but may be
required as fault could still be with sealed
refrigeration system)
- condenser blocked
- poor installation / ventilation
- frozen blocked evap coil
- unit gasket leaking (to cabinet seal / lid seal)
- door leaking air (bad gasket / door not self
closing)
- product; hot / blocking cabinet airflow
- overloaded from excess door openings / ambient
- fan motor / blade (condenser / Evap)
- App settings
- controller
- compressor / gas leak = arrange SWAP unit
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.
2, 3, 4
NO swap unit required
- condenser not clean
- poor installation / ventilation
- condenser fan motor / blade
- controller
17
Control probe failure
A critical system sensor has failed and the
cabinet can no longer operate.
2, 3, 4
NO swap unit required
- control Probe / circuit
- controller
18
Electrical over-current protection activated
The compressor was drawing too much
current and has shut down to prevent
permanent damage.
2, 3, 4
Take spare unit in case refrigeration system fault.
- condenser blocked
- poor installation / ventilation
- cabinet / unit gasket seals leaking
- door not self closing / gasket leaking
- product; hot / blocking cabinet airflow
- overloaded from excess door openings / ambient
- fan motor / blade (condenser / Evap)
- controller
- compressor / gas leak = SWAP unit
19
Failed to reach set temperature
The refrigeration system has been operating
continuously for a long period without
reaching the set temperature.
2, 3, 4
Take spare unit in case refrigeration system fault.
- condenser blocked
- poor installation / ventilation
- frozen blocked evap coil
- cabinet seal leaking / door / unit
- product; hot / blocking cabinet airflow
- overloaded from excess door openings / ambient
- fan motor / blade (condenser / Evap)
- controller
- compressor / gas leak = SWAP unit
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.
1, 2, 3, 4
- confirm if really too cold; change parameters
accordingly
22
Evaporator fan over-current protection
The current supplied to the evaporator fan
motor is too high.
2, 3, 4
NO swap unit required
- faulty fan motor
- fan blade fault (imbalance / debris / blockage)
- controller
23
Condenser fan over-current protection
The current supplied to the condenser fan
motor is too high.
2, 3, 4
NO swap unit required
- faulty fan motor
- fan blade fault (imbalance / debris / blockage)
- controller
24
Controller communication error
Controller has lost communication channels.
1, 2, 3, 4
