Toprovideabetteroverview,theclassied
messages are summarized in a condensed
state for the positioner according to the
NAMURRecommendationNE107.Thesta-
tus messages are divided into the following
categories:
Maintenance alarm
The positioner cannot perform its control
task due to a functional fault in the posi-
tioner itself or in one of its peripherals or
an initialization has not yet been suc-
cessfully completed.
Maintenance required
The positioner still performs its control
task (with restrictions). A maintenance
demand or above average wear has
been determined. The wear tolerance will
soon be exhausted or is reducing at a
faster rate than expected. Maintenance is
necessary in the medium term.
Maintenance demanded
The positioner still performs its control
task (with restrictions). A maintenance
demand or above average wear has
been determined. The wear tolerance will
soon be exhausted or is reducing at a
faster rate than expected. Maintenance is
necessary in the short term.
Out of specication
The positioner is running outside the
speciedoperatingconditions.
Ifaneventisclassiedas“Nomessage”,this
event does not have any affect on the con-
densed state.
