5.4.3 Analysis and monitoring
The analysis of the last three partial stroke
tests are saved with a time stamp in the
Analysis of measured data folder. A graph
of the last partial stroke test is shown in the
Partial stroke test folder.
Test completed successfully
When a partial stroke test has been complet-
ed successfully, the analyzed parameters are
displayed separately for the increasing and
decreasing characteristics.
Analysis of measured data (step response
test):
− 'Overshoot' (relative to the step height)
[%]
− 'Dead time' [s]
− 'T63' [s]
− 'T98' [s]
− 'Rise time' [s]
− 'Settling time' [s]
Analysis of measured data (ramp test):
− 'Overshoot' (relative to the step height)
[%]
The results of the rst partial stroke test are
used as the reference measurement.
Changes in the diagnostic parameters listed
below affect the test. The results of the next
following partial stroke test is used as the
new reference measurement:
− 'Step start'
− 'Step end'
− 'Activate ramp function'
− 'Ramp time (rising)'
− 'Ramp time (falling)'
− 'Delay time after step'
Test not completed
If the test was not completed, the reason for
cancellation is indicated in the correspond-
ing reading by the 'Maintenance alarm'
message. The positioner generates a 'PST/
FST' message with the selected status classi-
cation. 'Extended diagnosis' (Code 79) is
activated regardless of the status classica-
tion.
Diagnosis > Status messages > Extended
PST/FST
The 'No test available' status remains active
until a partial stroke is completed successful-
ly.
