a) Mounting the actuator
Î To mount the actuator, proceed as de-
scribed in the associated actuator docu-
mentation.
b) Aligning the travel indicator
scale
After mounting the actuator, the travel indi-

'0' on the travel indicator scale with the tip
of the stem connector clamp (see Fig.5-4).
1. Move the valve to the closed position.
2. Loosen the screws on the travel indicator
scale.
3. Align the travel indicator scale.
4. Fix the travel indicator scale into place
by tightening the screws.
