Cause : Analog input wire breakage comes when the wire-break monitoring for an analog input has responded. The input current of the analog input has undershot the threshold value parameterized in p0761[0...3].

p0756[0]: analog input 0 (only CU240D-2)
p0756[1]: analog input 1 (only CU240D-2)

1. Check the connection to the signal source for interruptions.
2. Check the magnitude of the injected current - it is possible that the infed signal is too low.
3. The input current measured by the analog input can be read in r0752[x]
