3-2-3 Cam attaching procedure
(1) Use the DA face of cam to turn the actuator main shaft clockwise (viewed from the positioner
front cover side) at the time of input signal increase. Use the RA face to turn it
counter-clockwise (reverse actuation). Correctly attach the cam to the flange part of feedback
shaft.
(2) Attach the cam in the procedure of loosening the hexagonal nut with flange first, setting the
using actuator to the starting position and then setting the cam reference line and the bearing
contact point of span adjusting arm unit to the matching position.
(3) Do not apply the supply pressure when attaching the cam as otherwise it is very dangerous.
(4) When the positioner is shipped from our plant, the cam is tentatively tightened to the shaft. Be
sure to firmly lock the cam to the lock nut (Tightening torque 3.6～4.1 Nm)

(1) Attach to the position at which the
positioner feedback shaft and the rotary
actuator main
concentric (range in which the spring pin
of feedback shaft edge enters the hole of
fork lever assembly shaft edge).
(2) If the separation joint type for IP610 is
made in a special specification, it can be
used for this connection.
