The device continues functioning in emergency mode but it must be replaced
as quickly as possible.
The emergency mode on the display is indicated by a blinking closed-loop op-

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. However,
the positioner continues operation according to its set point so that the process
remains in a safe state.
