The analog channels offer self-protective functions and diagnosis options in the following situa-
tions:
● Above range of analog value (input)
● Above range of analog value (output)
● Below range of analog value (input)
● Below range of analog value (output)
● Wire breakage
● Short circuit
For further information on behavior and indication of these errors, please refer to the AC500
