4) Connection of feedback pin and feedback lever (1)
There are several points to be careful of when connecting the feedback lever to the
device and the actuator feedback pin. Connect correctly.
- Only a pin with a diameter of 6 mm can be used.
- Insert the pin between the guide and the spring.

- Make the feedback lever perpendicular to the pin when viewed from the above.

Figure 2-7 Angle between Feedback Lever and Pin
- Mount the lever so that it is horizontal when opened by 50%.
- The allowable rotation angle of the feedback lever is horizontal ± 30°. If the angle
exceeds ±30°, the self-diagnostic function detects Valve Travel Detector Out of Range
and the device will not operate normally. (The accuracy is guaranteed when the
rotation angle is between ±4° and ±20°.)
Figure 2-8 Operation Angle of Feedback Lever
- When assembling the lever onto a rotary cylinder so that the shaft of the rotary
cylinder is positioned between the feedback pin and the 700 Series as shown in the
figure below, select Rotary/90° (for 90°) or Rotary/other (for angles other than 90°) as
the Actuator Type according to the rotation angle.
