The '52.XDIAG' Activating for extended diagnostics (Page 174)
parameter is set to 'On1', 'On2' or 'On3'.
• OFF
• On
Use this parameter to activate and deactivate the partial stroke
test. To activate monitoring, set the parameter to 'On'. Sub-
parameters are displayed.
Trigger the partial stroke test using:
• Buttons on the device
• A binary input
• Communication
• A cyclic test interval
The current status of the partial stroke test displayed in Diagnostic
value '12.PST - Monitoring of partial stroke test' (Page 214).
Diagnostic value '13.PRPST' - Time since last partial stroke test'
(Page 215) and Diagnostic value '14.NXPST - Time until next par-
tial stroke test' (Page 215) provide further information on the partial
stroke test.

0.0 ... 100.0
Use this sub-parameter to define the start position of the partial
stroke test in percent. Set the start position in a range from '0.0' to
'100.0'. The triggering of alarms (limits) is relative to the MPOS
scale.
The actuator moves during the partial stroke test from the start
position to the target position. The target position is determined
from the interaction between start position (A1.STPOS), stroke
height (A3.STRKH) and stroke direction (A4.STRKD).
