ALARMS AND ERRORS
COD.
ALARM TYPE
Solutions
Consequences
MINIMUM TEMPERATURE ALARM
AL
Check the temperature of the cell
The equipment will continue to operate regularly but checking the integrity
of the products stored is required.
MAXIMUM TEMPERATURE ALARM
AH
Check the temperature of the cell
The equipment will continue to operate regularly but checking the integrity
of the products stored is required.
DOOR MICRO SWITCH INPUT ALARM
id
Check the causes for input activation / See parameters i0 and i1
Effect established by parameter i0
MALFUNCTION INPUT ALARM
iA
Check the causes for input activation / See parameters i0 and i1
Effect established by parameter i0
OVERHEATED CONDENSER ALARM
COH
Check temperature of the condenser / See parameter C6
The device will continue to operate regularly
COMPRESSOR LOCKED ALARM
CSd
Check the temperature of the condenser / See the parameter C7 / turn off and
on the instrument: if at restart the temperature of the condenser is > of par. C7,
disconnecting the power supply and cleaning the condenser is required
The condenser will be turned off
dFd
DEFROSTING ENDED FOR MAXIMUM DURATION
Check the integrity of the evaporator probe. Press a key to restore normal
display.
The device will continue to operate regularly but performing an
additional manual defrosting is recommended.
Pr1
CELL PROBE ERROR
Check integrity of the probe and check the instrument-probe connection.
Check temperature of the cell
compressor operation will depend on the C4 and C5 parameters
Pr2
EVAPORATOR PROBE ERROR
The same of the previous case but relative to the evaporator probe
if the P4 parameter is set to 1, defrosting will last for the time set with
the parameters d3;
if the P4 parameter is set to 1 and the d8 parameter is set to 2, the
instrument will operate as if the d8 parameter was set to 0;

for 4 s: the display will show "PA"
or key
within 15 s to set "-19"
or do not operate for 15 s: the display will
or key
or key
within 15 s
or do not operate for 15 s
for 4 s or do not operate for 60 s.
Translation of the original instructions
After resolving the cause of the alarm, the instrument restores normal
operation, except for the following alarms:
• " dFd " - press any key;
• "CSd" - turn the instrument off or disconnect power supply
FAULT
The following items will help you find possible solutions to some
troubles the unit could be subject to. It is understood that the
information given here does not cover all possible cases.
Whenever a safety device triggers, it means that there is a
malfunction; before resetting it, check and remove the cause.
After making the above checks, if the fault persists contact your after-
sales service. Remember to specify the nature of the defect, the
appliance's code and serial number (you will find on its nameplate).
PROBLEM
Possible cause
What to do
1
APPLIANCE DOESN'T START
1.1
Appliance isn't connected to the power supply
Check that the plug is fitted into the mains power supply socket correctly.
2
COMPRESSOR RARELY STOPS
2.1
Room temperature is too high
Ensure proper ventilation to the room
2.2
Refrigerated cabinet condenser is dirty
Check it on a regular basis and clean it thoroughly.
2.3
Low refrigerant charge
Call an authorised technical support centre to find and repair any
leaks and to recharge the compressor with refrigerant.
2.4
Door gaskets do not ensure proper seal
Call an authorised technical support centre to perform the
necessary replacement
2.5
Frost build-up on the evaporator
Do not place hot or high water content foodstuffs into the
appliance and, if needed, perform a manual defrost cycle
2.6
Evaporator motor fan(s) damaged
Call an authorised technical support centre to perform the
necessary replacement
3
OVERFLOWING OF SELF-EVAPORATING CONDENSATE TRAY
3.1
Hot or high-water content foodstuffs are being introduced into the
appliance too often.
Do not introduce hot or high water content foodstuffs into the appliance
3.2
Doors and/or drawers are opened too often.
Pay attention to the conditions of use of your appliance
4
COMPARTMENT TEMPEATURE TOO HIGH
4.1
Refrigerated cabinet condenser is dirty
Check it on a regular basis and clean it thoroughly.
4.2
Feeble aeration of the zone around the technical compartment.
Remove any obstructions for a correct airflow
4.3
Hot air entering the compartment.
Check the correct closure of the door and the gasket to be proper.
If it's not possible to adjust functioning, call a technical support
centre to perform replacement and regulations
4.4
Frost build-up on the evaporator
Perform a manual defrost cycle
