INSTALLATION
Example of attaching to actuator
Example 1.
Case of directly attaching to diaphragm valve.
Example 2.
Case of using a bracket.
Connection with Feedback Lever
Attach in the position that the valve stem and lever form a right angle when the
input signal is 50%. Attach to the position that the runout angle is within the range
of 10 to 30°.
INSTALLATION cont.
Direct Action & Reverse Action
Attach the cam in the procedure of loosening the hexagonal nut with flange first,
setting the actuator to the starting position and then setting the cam reference line
and the bearing contact point of span adjusting arm unit to the same position. Do
not apply the supply pressure when attaching the cam as otherwise it is very dan-
gerous. When the positioner is shipped out, the cam is tentatively tightened to the
shaft. Be sure to firmly lock the cam to the lock nut [tightening torque 17.7 to 22.1
in-lbs (2.0 to 2.5 NM)].
AIR PIPING CONNECTION
Fully purge the pipe to remove foreign matter. Use a clean supply air fully
removed of humidity and dust. Use a Series AFR filter regulator to keep supply
air pressure constant.
