Connection with Feedback Shaft
(1) Screw in a fork lever-type fitting to the major
shaft of actuator and adjust its height to avoid
interference with the fork pin unit.
(2) Adjust the angle of the fork lever-type fitting
to avoid interference with the positioner body
while the actuator is fully opening from a
fully-closed condition

.
(3) Mount so that the feedback shaft of the
positioner and major shaft of actuator are
almost aligned (where the spring pin at the
end of the feedback shaft engages with a
hole at the end of the fork lever-type fitting
axis).

2: Fig. 7 shows the details of how to adjust the fork
lever angle. Adjust the fork lever angle to avoid
interference with the positioner foot when the
positioner fork pin unit rotates along with the
actuator. Also, the effective angle of the
positioner angle sensor is +/-60
o
, and the fork
lever-type fitting has to be fixed to remain within
that range. The angle can be checked by
following the instructions in

3: Pay attention not to apply a strong impact to a feed back shaft of the positioner when the shaft is
connected to a fork lever-type fitting. The angle sensor might be damaged due to the strong impact. Do
not apply any impact when the positioner and actuator are connected.
