x signal
Actuator's measured value recording failed.
The conductive plastic element is defective.
The device continues functioning in emergency mode but it must be re-
placed as quickly as possible.
The emergency mode on the display is indicated by a blinking closed-
loop operation icon and 4 dashes instead of the position reading.
Note on the open-loop operation:
If the measuring system has failed, the
positioner is still in a reliable state. The positioner switches to emergency
mode where the position cannot be accurately controlled anymore. How
-
ever, the positioner continues operation according to its set point so that
the process remains in a safe state.
Status classification
