The input current of the analog input has undershot the threshold value parameterized in p0761[...3]. The manual's first action is: “Check the connection to the signal source for interruptions. Check the magnitude of the injected current - it is possible that the inefed signal is too low. The input current measured by the analog input can be read in r0752[X].”

What F03505 means
CU: Analog input wire breakage p. 688
Common causes
- The input current of the analog input has undershot the threshold value parameterized in p0761[...3]. This fault only occurs when p0756[0...1] = 1 (2 ... 10 V with monitoring) or p0756[0...2] = 3 (4 ... 20 mA with monitoring) is set. p. 688
What to do
- Check the connection to the signal source for interruptions. Check the magnitude of the injected current - it is possible that the inefed signal is too low. The input current measured by the analog input can be read in r0752[X]. p. 688
