Status for reference stroke time in seconds
Use this sub-parameter to measure the reference stroke time for the
partial stroke test.
The reference stroke time corresponds to the controlled movement
from the start position to the target position.
If the positioner has already been initialized, the calculated average
travel time of the control valve is displayed as a reference value.
● NOINI: Positioner has not yet been initialized.
● (C)##.#: An average travel time of 1.2 seconds, for example, is
shown in the display as 'C 1.2', where 'C' stands for 'calculated'.
The average travel time can be used as a reference stroke time.
However, it merely represents a rough guideline value.
● FdInI: 'FdInI' is displayed if the start position cannot be
approached or the stroke target cannot be reached. 'FdInI'
stands for 'failed PST initialization'.
● rEAL: Set the sub-parameters 'A1.STPOS' to 'A5.RPMD'
according to your requirements. Then start measuring the
reference stroke time by pressing the
seconds. The display shows 'rEAL' during these 5 seconds.
The device then moves to the configured start position
automatically and executes the desired stroke. The current
position in percent is continuously shown on the display. 'inPST'
for 'initialize partial stroke test' appears in the lower line of the
display.
