Presumed Cause
Handwheel or other travel
restriction in place.
The handwheel on the actuator
is not in neutral or is partially
engaged
Extreme valve sticking
Insufficient air supply
Remedy
1. Verify mounting and link-
age are correct.
2. Run Auto Tune.
3. Run Manual Tune.
4. Verify supply pressure.
see if
Using ValVue Trend,
the valve has friction
greater than 50% of the
spring range or
and
Observe the valve
see if the movement
jumps significantly with
a smooth
input signal.
Repair the valve when
possible.
Using ValVue or another
® that
HART interface, verify
the air supply setting.
It must be set to 5 psi (.35
bar, 34.5 kPa) greater than
the spring final.
For double-acting actuator,
the air supply must be that
required to generate the
force to move the valve.
Increase the air supply per
the actuator requirements
