THERMAL SWITCH
Compressor
thermal switch
tripped.
Compressor overload.
Inadequate power supply.
(connector disconnected).
Damaged compressor.
The blast-chiller is locked and only the
condenser fan remains in operation.
Check for any obstructions in the
condensing coil.
CALL CUSTOMER SERVICE.
HIGH PRESSURE
Safety pressure
switch tripped.
The working ambient
temperature is too high.
The condenser fan does not
work.
The food load exceeds the
suggested values.
Condensing coil clogged with
dust.
Reposition the machine to ensure proper
ventilation.
The blast-chiller is locked and only the
condenser fan remains in operation.
Check the connections of the fan and/or
run condenser if present.
Check for any obstructions in the
condensing coil.
Clean the condensing coil.
CALL CUSTOMER SERVICE.

Safety pressure
switch
intervention.
Refrigerant leak resulting in
insufficient charge.
Evaporator fan not working.
Solenoid valve locked.
Evaporator coil with ice
The blast-chiller is locked and only the
condenser fan remains in operation.
Check solenoid valve functionality.
Defrost.
Check fan connections.
CALL CUSTOMER SERVICE.
DOOR OPEN
Door open
Stop cycle.
The door stays open beyond the
permitted limit. Faulty or
interrupted closing device
(micromagnetic).
Make sure that the machine door is closed
and that any physical obstructions are not
preventing the door from closing.
Check micro connections.
If the alarm remains active call Service.
HIGH
TEMPERATURE
High cabinet
temperature
Door open.
Food in the cold cabinet is too
hot.
Check the cabinet probe.
Refrigerant leak.
Ice or frost on evaporator.
Cabinet temperature has exceeded the set
limit in addition to the signal delay.
Cycle in continuous operation.
Check parameter A4.
Perform defrost cycle.
Check the condition of the gasket.
Check the cabinet temperature with an
external thermometer.
If the alarm persists even when the cabinet
temperature is low, call Service.
LOW
TEMPERATURE
Low cabinet
temperature (only
for positive or
negative holding
cycles)
Low set delay time.
Set temperature difference too
small.
Evaporator frozen.
Evaporator fan not working.
Compressor always ON.
Non-compliant temperature
probe
The cabinet temperature is below the cycle
temperature setpoint minus the differential.
The cycle will continue until it stops.
Open the door to raise the temperature
inside the cabinet and check after about 3
minutes.
Start a manual defrost cycle.
Check compressor relay or contactor.
Check internal temperature with reference
thermometer
Check parameter A1.
If the problem persists, call Service.
CYCLE DURATION
Cycle time over
the permitted limit
Food load in cabinet too high.
Food too thick.
Food temperature too high.
Evaporator fan fault.
Refrigerant leak.
The core temperature has not reached the
setpoint within the set time period.
Reduce thermal load.
Reduce food thickness.

NEEDLE
Fault on all
sensors.
Improper use of the needle
probe (e.g. pinched or frayed
wire).
Connector fault.
Probe fault.
PCB fault.
Cycle running:
•
The cycle continues in probe mode until
at least one of the 3 needle probe points
is running.
•
The cycle switches to time mode if none
of the 3 sensors are operating.
During STANDBY phase:
•
The cycle can be started as long as at
least one of the 3 points is active.
