Description
PS Vent Amount: Position change in the direction of the safety position (venting of positioner
output 1) by which the valve is to be moved.
Timeout Time: If the valve does not reach the new valve position, which has changed by the
amount defined by "PS Vent Amount", within the defined time (Timeout Time), an alarm is issued.
IMPORTANT (NOTE)
The default setting for this time is automatically determined by Autoadjust (only in
Autoadjust mode: Valve Ranges, Full).
Use this parameter to define the time interval according to which the "Partial Stroke Test" is
triggered on a cyclical basis.
Use this parameter to trigger the partial stroke directly.
The result is shown on the display:
Test Passed – Test was successful
Test Failed – Test was not successful
NOTICE – Property damage!
During the test, the valve no longer follows the setpoint current. This change in the
valve position may have a detrimental effect on the process.
