ERRORS
CODE MEANING
Pr1
Cabinet probe error
Remedies:
• look at parameter P0
• check the integrity of the probe
• check the connection instrument-probe
• check the cabinet temperature
Effects:
• equipment in “standby”; no cycle can be selected or started
• during blast chilling, the cycle is interrupted
• during preservation, the compressor activity depends on parameters C4 and C5 or C9
• defrosting is never activated
• the heating elements of the door do not turn on
• the “AL” minimum temperature alarm is never activated
• the “AH” maximum temperature alarm is never activated
Pr2
Needle Probe Error
Remedies:
• look at parameter P0
• check the integrity of the probe
• check the connection instrument-probe
• check the cabinet temperature
Effects:
• equipment in “standby”; the blast chill cycles with probe are timed
• during positive blast chilling with probe, the duration of the cycle is established by parameter r1
• during negative blast chilling with probe, the duration of the cycle is established by parameter r2
• heating is interrupted while heating the needle probe
Pr3
Evaporator probe error
Remedies:
• look at parameter P0
• check the integrity of the probe
• check the connection instrument-probe
• check the cabinet temperature
Effects:
• if parameter P4 has value 1, the defrost will last the timeyou will have set with parameter d3
• if parameter F0 is set to 1, parameter F16 has no effect
• if parameter F4 is set to 1, the equipment works as if the parameter were set to 2
