CODE MESSAGE
Pr1 Cabinet probe error
Remedies:
•
see P0 parameter
• check probe integrity
• check probe-device connection
• check the cabinet temperature
Consequences if the error occurs while in "stand-by" mode:
• if parameter C11 is set to 0, it will not be possible to start any of the cycles
• if parameter C11 is set to 1, the pin probe will function as the cabinet probe and
only timed cycles will be allowed to start
Consequences if the error occurs during a timed chilling operation:
• if parameter C11 is set to 0, the cycle will be interrupted
• if parameter C11 is set to 1, the pin probe will function as the cabinet probe and
the chilling operation will continue
Consequences if the error occurs during a set-temperature chilling operation:
• if parameter C11 is set to 0, the cycle will be interrupted
• if parameter C11 is set to 1, the pin probe will function as both the cabinet probe
and pin probe and the chilling operation will continue
Consequences if the error occurs during a storage operation:
• parameter C11 is set to 0, the compressor activity will depend on parameters C4,
C5 and C6
• if parameter C11 is set to 1, the pin probe will function as the cabinet probe and
the storage operation will continue
Pr2
Pin probe error
Remedies:
• the same as for the previous case, but in relation to the pin probe
Consequences if the error occurs while in "stand-by" mode:
• only timed operation cycles will be allowed to start
Consequences if the error occurs during a timed chilling operation:
• chilling will continue
Consequences if the error occurs during a set-temperature chilling operation:
• chilling will continue in timed mode
Consequences if the error occurs during storage mode:
• storage will continue
