8.3 Fault/malfunction

A status classification is assigned to all status
and fault alarms in the positioner. The de-
fault settings of the status classification are
listed in the code list.
Note
The assignment of the status classification can
be changed in the TROVIS-VIEW software.
Refer to the Operating Instructions for the
valve diagnostics
u
CD-ROM for more details.
To provide a better overview, the classified
messages are summarized in a condensed
state for the positioner according to the
NAMUR Recommendation NE 107. The status
messages are divided into the following cate-
gories:
− Maintentance 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
78
EB 8389 on the enclosed
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 specification
The positioner is running outside the
specified operating conditions.
Note
If an event is classified as 'No message', this
event does not have any affect on the con-
densed state.
The condensed state is displayed represented
by the following icons:
