A. PST≠OFF
Case 1: ... a partial stroke test
is successfully executed with‐
in the reference stroke time or
the function is deactivated.
Case 2: Move the actuator into
the range of the PST start tol‐
erance. Or increase the PST
start tolerance until the actua‐
tor (PST start position) is with‐
in the PST start tolerance.
Start the partial stroke test
again.
Possible causes
Compressed air failure, actua‐
tor fault, valve fault (e.g. block‐
ade).
The device has been config‐
ured or is in the manual mode
The contact connected to the
binary input was active (e.g.
packing gland monitoring,
overpressure, temperature
switch).
The total path covered by the
actuator exceeds one of the
configured thresholds.
The number of changes of di‐
rection exceeds one of the
configured thresholds.
Wear and tear of the valve
seat, deposits or foreign bod‐
ies in the valve seat, mechan‐
ical misalignment, friction
clutch moved.
Wear and tear of the valve
seat, deposits or foreign bod‐
ies in the valve seat, mechan‐
ical misalignment, friction
clutch moved.
Increased packing gland fric‐
tion, mechanical gap in the po‐
sition feedback.
Case 1: Valve is stuck or rus‐
ted. Increased stiction.
Case 2: Valve is present in the
safety position.
