DESCRIPTION
POSSIBLE CAUSES
• Food probe misuse (for exam-
ple, wire pulled or squeezed)
Core probe fail-
• Connector failure
ure sensor n°5
• Probe failure
• PCB failure
• Food probe misuse (for exam-
ple, wire pulled or squeezed)
Core probe fail-
• Connector failure
ure sensor n° 6
• Probe failure
• PCB failure
• Power supply missing
Supply power
• Supply power system failure
missing
• Other electrical issues (for
example current dispersions)
• Battery of User interface is low
Low battery
• Electronic board failure
• Door left open
Cavity high
• Food too hot in the cavity
temperature
• Issue with parameter ady or
with temperature measurement
• Fan condenser overload (exam-
ple: room temperature too high)
• Electrical issue (example: con-

failure
• Gas leak
• Compressor damaged
• The door remained open
beyond the time limit set whit
Door open
the active cycle
• Door closure recognition system
is failed
• ACU board not programmed or
ACU protocol
programmed with an incompat-
error
ible Software version
• Electronic boards disconnected
ACTIONS
• Current running cycle:
a) the cycle continues in probe
mode until at least one out of the 6
food probe points is working.
b) the cycle switches to time mode
if none out of the 6 food probe
points is working.
• During STANDBY:
a) the cycle can be started until at
least one point is working.
b) the cycle can be started in time
mode in case all points are failed.
• To restore full functionality, call
Service.
• Current running cycle:
a) the cycle continues in probe
mode until at least one out of the 6
food probe points is working.
b) the cycle switches to time mode
if none out of the 6 food probe
points is working.
• During STANDBY:
a) the cycle can be started until at
least one point is working.
b) the cycle can be started in time
mode in case all points are failed.
• To restore full functionality, call
Service.
• Current running cycle: the cycle
restarts automatically when the
power is back.
• The machine was not in operation
for a certain period of time: check
initial and end time.
• Check the plug or general electric
control panel.
• If the alarm reoccurs, Call Service.
Problem with battery of internal clock.
Functions related to the clock will not
operate (example: HACCP event
recording will be wrong).
CALL SERVICE
• The cavity temperature has
exceeded the set limit, in additional
to the signal delay time.
• Current running cycle: the cycle
continues.
• If the alarm persists even if the
cavity temperature is low, call
service.
• The chiller will be blocked and only
fan condenser runs.
• Check if there is any obstruction at
the suction air condenser.
CALL SERVICE
• Ensure the chiller door is closed
and any physical obstruction is not
preventing the door closure.
• Start new cycle: if either a new
cycle will not start or the alarm
persists even with the door closed,
Call Service.
• Communication protocol error
detected.
• If the problem persists, Call Service.
