The SIG-ERROR function is used to detect a fault on the input signal.
fault detection
Fault detection can be selected at 4 – 20 mA and with a Pt 100 signal.
4 – 20 ma
Fault with input signal ≤→3.5 mA (± 0.5 % of end value, hysteresis 0.5 % of end value)
pt 100
Fault with input signal 225 °C (± 0.5 % of end value, hysteresis 0.5 % of end value)
If other signal types are selected or if process controllers are not activated, the respective menu branch is
hidden. If this configuration does not allow either of the two fault detections,
not available is indicated in
