Possible
causes
Compressed air
missing, actuator
fault, valve fault
(e.g. blockage).
The device is
configured or is in
manual mode.
The contact
connected to the
binary input became
active (e.g. stuffing
box monitoring,
overpressure,
temperature switch).
The sum of the
distance covered by
the actuator exceeds
one of the set
thresholds.
The number of
changes of direction
exceeds one of the
set thresholds.
Wear of the valve
seat, deposit or
foreign matter in
the valve seat,
mechanical
misadjustment, friction
clutch misadjusted.
Wear of the valve
seat, deposit or
foreign matter in
the valve seat,
mechanical
misadjustment, friction
clutch misadjusted.
Increased stuffing box
friction, mechanical
batches of the
position feedback.
Valve jams or is
rusted in place,
increased friction
actuator fault, valve
fault, valve jams,
increased friction,
compressed air drop
Pneumatic leakage
