Start manufacturer reference
Note:
By selecting and executing 'Cancel
manufacturer reference' or by press-
ing the rotary pushbutton, the manu-
facturer reference test is canceled (Test
information = 'Test canceled manual-
ly'). After canceling the manufacturer
reference test, the positioner remains
in the manual mode.
In TROVIS-VIEW 4 the test information and
progress flag of the manufacturer reference
test are displayed. When the manufacturer
reference test has been successfully complet-
ed, the Test information reading indicates
'Test completed successfully'.
Note concerning editing set points
−
The entered set points must continuously
increase from 'Set point 1' to 'Set point
11'.
−
The valve moves to the set points in steps
of 0.1 %. Set points must be rounded up
to two decimal places.
−
User-defined settings can be saved for
other functions (e.g. process reference
test) in a file.

Assessment
While the manufacturer reference test is
running, the positioner determines three
alarm limits. The relation between Valve
position x [%] and Sound level [dB] is shown
in TROVIS-VIEW 4:
−
Relation 1: Valve position and sound lev-
el at 0 % position
−
Relation 2: Valve position and sound lev-
el at the point where the curve in the
'Leakage sensor manufacturer reference'
graph starts to rise monotonously
−
Relation 3: Valve position and sound lev-
el at the last measurement
9.1.1.2
Resetting single status
messages
The short-term monitoring (parameters, mea-
sured data and analysis) can be reset by se-
lecting and executing the command "Reset
'leakage sensor manufacturer reference".
If the test is restarted and a test analysis has
already been performed, the analysis of the
old manufacturer reference test is overwrit-
ten.
