Confirmation Of Feedback Lever Angle - SMC Networks IP8001 Series Operation Manual

2. Confirmation of feedback
lever angle
Confirm the angle of the feedback lever of the positioner. Confirm
that the actuator operates within -30 to 30 Deg on the display

No.
OUT1 output is 0MPa
at the end. Ensure "Angle" is -30 Deg or more, and 30Deg
1
or less.
Paying attention to the operation of the actuator, rotate the
pilot valve unit auto/manual switch by approx. 1/8 turn for
2
manual direction
OUT1 output becomes max., and the valve stem becomes
3 end position which is the opposite of item 1 above. And,
Ensure "Angle" is -30 Deg or more, and 30 Deg or less.
If the LCD displays shows "-99 or 99", indicating that the value
4 exceeds +/-30 at the end position, readjust the position of the
positioner so that the angle is within the specified range.
After confirmation, turn the auto/manual switch to auto
5
direction to tighten properly.
4: Although the rotation angle of the feedback lever is adjustable within
+/-5 to +/-15 degrees, setting at +/-5 degrees is recommended to avoid
reduction in linearity due to geometric error. The rotation angle of the
standard stroke of the positioner is 10 to 30 degrees.Rotation of less than
10 degrees or more than 30 degrees is not acceptable as the mounting
condition.
5: A Description of pressure gauges mounted on the positioner are as
shown in Fig. 6.

6: Auto and manual mode can be switched by rotating the pilot valve
unit auto/manual switch screw to the manual (M) side as shown in
Fig. 7. A small stopper screw in the top is to prevent loosening and
must not be tampered with or loosened. Also, a sensitivity holding
screw is set prior to factory shipment and must not be accidentally
rotated.
