2.1 Status messages
The valve diagnostics integrated into the po-
sitioner generates classied status messages.
Messages generated from the analysis of the
diagnosis can be classied according to the
possible causes. See u Section 4 to 13.
The following classications are possible:
− No message
If an event is classied as “No message”,
this event does not have any affect on the
condensed state.
− 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.
− Maintenance request/maintenance re-
quired
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.
− Out of specication
The positioner is running outside the
specied operating conditions.
− Failure
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.
You can view these messages in TROVIS-
VIEW4 in the Diagnostics folder (> Monitor-
ing) and its subfolders. The 'Positioner sta-
tus', 'Valve status', 'Actuator status' and
'Valve position status' messages provide a
condensed state of the status messages of
each subfolder.
2.1.1 Resetting status messages
When a status message is generated, you
should rst locate the source of the fault and
take action to remedy it.
For recommended action concerning the sta-
tus messages see u Section 17.2.
Status messages can be reset individually or
using the reset function. Table 2 on page
15 contains an overview on how the di-
agnosis can be reset. Resetting is performed
in the Diagnostics folder (> Service/mainte-
nance > Reset).
If you want to keep measured data and the
analysis after resetting the positioner, it is
possible to upload them onto a computer.
Resetting single status messages
− Status messages represented by a code
in the positioner can be conrmed at the
positioner itself. Select the error code
and conrm it by pushing the rotary
pushbutton. See the standard instructions
of the positioner u EB 8384-6S EN.
− On resetting histograms and diagrams,
the data for short-term monitoring are
also reset.
