Siemens SIPART PS2 Kit Installation Instruction page 5

Install the Mounting Plate and PS2 Assembly to the Actuator
1. First, use an air regulator to position actuator/valve to the mid-stroke position. This will ease with
assembly.
2. While positioning the mounting plate & PS2 assembly to the actuator, be sure the feedback pin
intersects the feedback arm and spring clip. You will need to slide down the stem block and pin
down the actuator shaft to secure mounting plate to actuator.
Be sure the feedback pin engages the feedback arm and spring clip as you assemble.
Remember you can unscrew the pin from the stem block if you need more pin length.
It may also be necessary to cut the feedback pin to length. If cutting the pin is necessary be
sure a ¼" of the pin protrudes through the feedback arm.
3. Once mounting plate & PS2 assembly is fully down on actuator, secure mounting plate to actuator
using the four M6 x 16 hex bolts and lock washers.
4. Once feedback pin is properly protruding through feedback arm, tighten pin to stem block using
the 5/16" hex nut.
5. Slide the PS2 along the four slots of the mount plate so the feedback arm exceeds 30 degrees of
rotation when the valve fully strokes. The maximum rotation is 100 degrees. To achieve the best
mechanical feedback performance, try to get as much physical rotation without exceeding 100
degrees.
6. Once rotation is achieved, secure PS2 to multi-mount plate by securing the four M6 bolts to PS2.
7. Go to the Initial PS2 Setup section on the next page.
