ERRORS
The following table illustrates the meaning of the error codes
Code
Meaning
Pr1
Cabinet probe error.
Solutions:
- check the value of parameter P0
- check the integrity of the probe
- check the device-probe connection
- check the temperature of the cabinet.
Main consequences:
- if the error occurs during the “stand-by” status, no operating cycles can be selected or started
- if the error occurs during blast chilling or deep freezing, the cycle will be interrupted
- if the error occurs during storage, compressor activity will depend on parameters C4 and C5
or C9
- defrosting will never be activated
- the door resistances will never be switched on
- the minimum temperature alarm (“AL” code) will never be activated
- the maximum temperature alarm (“AH” code) will never be activated
Pr2
Needle probe error.
Solutions:
- the same as the cabinet probe error (“Pr1” code) but relative to the needle probe.
Main consequences:
- if the error occurs during the “stand-by” status, temperature-controlled operating cycles will
be started by time-control
- if the error occurs during temperature-controlled blast chilling, this will have duration of the
time set by parameter r1
- if the error occurs during temperature-controlled deep freezing, this will have duration of the
time set by parameter r2
- if the error occurs during needle probe heating, this operation will be interrupted.
Pr3
Evaporator probe error.
Solutions:
- the same as the cabinet probe error (“Pr1” code) but relative to the evaporator probe.
Main consequences:
- if parameter P4 is set at 1, defrosting will last for the period of time established with
parameter d3
- if parameter F0 is set at 1, parameter F16 will have no effect
- if parameter F4 is set at 1, the device will operate as if it were set at 2.
