8.3 Fault/malfunction
A status classication is assigned to all status
and fault alarms in the positioner. The de-
fault settings of the status classication are
listed in the code list.
The assignment of the status classication
can be changed in TROVIS-VIEW and over
the PROFIBUS-PA parameters. Refer to the
Operating Instructions for the valve
diagnostics uEB8389 and the
Conguration Manual uKH8384-4 on the
enclosed CD-ROM for more details.
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.
− Process-related malfunction/
out of specication
The positioner is running outside the
specied operating conditions.
− Function check
Test or calibration procedures are per-
formed in the positioner. The positioner is
temporarily unable to perform its control
task as long as the procedure is taking
place.
If an event is classied as “No message”, this
event does not have any affect on the con-
densed state.
