Criteria
Cause of problem
1. How to diagnose
1) If the Sump temperature right before the start of compressor = Tsump.ini, current compressor's SUMP temp =Tsump. real,
When the difference between Tsump.ini and Tsump.real is an absolute value so that it cannot be more than 2˚C,
In other words, the condition of Tsump.real-Tsump.ini<2˚C has been satisfied for 60 minutes since a compressor started, it is diag-
nosed as an error.
After 60 minutes of compressor operation, there will be no Sump sensor dislocation detection.
2. How to check
1) Check if a sensor of the relevant compressor has been dislocated in accordance with error code, assemble and correct the error.
