What is the UCF trip code on the ATS22?

This is a motor underload (undercurrent) condition based on the setting of parameters UId and UIt in the Protections menu, PrO.
UId is the undercurrent threshold as a % of parameter In, motor rated current.  It can be set to oFF to disable the feature.
UIt is the undercurrent time delay.
In a run state, if the motor current remains below the UId threshold for the UIt time period, the ATS22 will trip on UCF.
