INTERNAL DIAGNOSTICS

5.1 Internal diagnostics
CODE EXPLANATION
Pr1 Cabinet probe error
Solution:
• look at parameter P0
• check the integrity of the probe
• check the connection between controller and probe
• check the cabinet temperature
Effects:
• the compressor will be turned on
When the conditions that triggered the alarm are no longer present, the
controller will return to normal operation.
