9 Malfunctions
Malfunctions are indicated on the display by
errorcodes.Section11.4listspossibleerror
messages and recommended action.
The error codes appear on the display corre-
spondingtotheirstatusclassicationsetover
thecondensedstate(Maintenancerequired/
Maintenance demanded:
,Outofspeci-
cation:
blinking, Maintenance alarm: ).
If 'No message' is assigned to the error code
asthestatusclassication,theerrorisnotin-
cluded in the condensed state.
Astatusclassicationisassignedtoevery
error code in the default setting. The assign-
mentofthestatusclassicationcanbe
changedinTROVIS-VIEWandoverthepa-
rametersoftheDD.Refertotheoperatingin-

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.
