After the activation has been successfully
completed,
YES
appears on the display.
Note!
On entering the wrong activation code, the
display returns to Code 0. The activation of
EXPERT
+
has been unsuccessful.
After an incorrect activation code has been
entered three times, Err appears on the
display after selecting Code 48 and d8. An
activation code can only be entered again
after the positioner has been reset to its
default settings (Code 36).
1.4 Actuator and valve
specification data
To correctly analyze the diagnostic data,
several actuator and valve specifications
need to be entered for the EXPERT
+
diagnos
-
tics.
Enter the required data in the
Identification
folder (>
Positioner > Actuator
) as well as
(>
Positioner > Valve
).
Download the data to the positioner.
The
Model
and
Booster
parameters in the
Actuator
folder and
Stuffing box
parameter
in the
Valve
folder need to be entered.
The default settings of these parameters are:
4
Model
> Single-acting
4
Booster
> Not present
4
Stuffing box
> Self-adjustable
These parameters do not need to be
changed if the control valve also has these
default settings.
1.5 Start the reference test
After EXPERT
+
has been activated properly,
the reference graphs for future diagnostic
purposes need to be plotted to allow the di
-
agnostics to function in their full scope.
The reference graphs are plotted automati
-
cally after the positioner has been initialized
when the EXPERT
+
has been activated (e.g.
already on delivery).
On activating EXPERT
+
at later time, the ref-
erence graphs are plotted after the
positioner is re-initialized.
If reference graph plotting is to be started sep-
arately in an initialized positioner or if graphs
are to be replotted, proceed as follows:
Set the positioner to manual mode:
Turn
→
Code

blinks.
Turn
→
