Cause : ULC configuration - comes when user load curve configuration error due to speed points inconsistent or Frequency points inconsistent.

Check the auxiliary code. See actions for each code below :

1. 0000 - Speed points inconsistent : Check that each speed point (parameters 37.11… 37.15) has a higher value than the previous point.
2. 0001 - Frequency points inconsistent : Check that each frequency point ( 37.16… 37.20) has a higher value than the previous point.
3. 0002 - Underload point above overload point : Check that each overload point ( 37.31… 37.35) has a higher value than the corresponding underload point ( 37.21… 37.25).
4. 0003 - Overload point below underload point : Check that each overload point ( 37.31… 37.35) has a higher value than the corresponding underload point ( 37.21… 37.25).
