* If the 'positioning timeout' alarm has been set, the positioner monitors if the position changes more than 0.1 % over 5 seconds. If not, a 'Valve Blocked'
diagnosis notice is output. No alarm is output in the end position.
Possible cause
Defective position sensor
Friction too high
Positioning time up-scaled
friction high
Change disturbance variables
Valve seat is damaged
Friction too high
Friction too high
Defective DCS card
Auto adjust has not yet been
executed
Test function activated
Many valve strokes
Many valve strokes or vibrating
valve
Temperature sensor defective
Temperature is too high or too
low
Output piping mixed up
Faulty electronics
Leakage in actuator, piping,
connections, or positioner
Leakage in chamber 1 of the
actuator or pneumatics output
line 1
Leakage in chamber 2 of the
actuator or pneumatics output
line 2
