4 … 20 mA signal missing Electrical connection faulty Check connection, correct, if necessary
Voltage supply missing Check cables for breaks; repair if nec-
essary
Operating voltage too low, load resist-
ance too high
Check, adapt if necessary
Current signal greater than
22 mA, less than 3.6 mA
Sensor electronics defective Replace device or send in for repair de-
