F0799 fault in WEG CFW701 Drive indicates a High Level of the External PID 2 Process Variable. This means the second external PID feedback sensor remained above the safe threshold, triggering a system fault.
Cause:
Parameter P1095 is programmed in 2 and the External PID controller 2 feedback value is remaining above the value programmed in P1098 for the time programmed in P1099.
Remedy:
Verify that the process pressure, level, or variables are within expected system parameters. Check the sensor output and parameter values for P1095, P1098, and P1099.
