mounting screw is located in the groove
of the actuator stem.
3. Mount cover plate (10) with narrow side
of the cut-out (Fig. 5-9, on the left) point -
ing towards the signal pressure connec-
tion. Make sure that the gasket (14)
points towards the actuator yoke.
4. Check the pin position of the follower pin
(2) on M lever (1). Refer to travel tables
for type of attachment. If necessary,
change the pin position (see section 5.4).
5. Insert molded seal (15) into the groove of
