NEW LINEAR MOUNTING INSTRUCTIONS

Tools Required:
• Wrenches (5/16", 3/8", 7/16", 1/2" 9/16", 10 mm, and 13mm)
• Slotted Screwdriver
• Terminating Screwdriver
• Hex Wrench Set

BEFORE CONNECTING THE ACTUATOR AND VALVE STEM:

1 Attach the sliding pin assembly (Keys 2, 3, 4, 5, 6, & 7) to the connecting
block bracket (Key 1), refer to Figure 4B for assembly details. Center the
sliding pin assembly in the connecting block pin slot as shown in Figure 4A.
Hand tighten the hex nut (Key 7).
2 Using lock washers (Key 9) and cap screws (Key 10), mount the yoke bracket
(Key 8) to the Siemens PS2 Positioner as shown in Figure 4C. NOTE: Travel
markings are engraved on the front of the yoke bracket. Travel markings
should be visible when mounting the PS2 to the actuator yoke, as such when
looking at the cover of the PS2 housing you should be able to see the travel
markings.
3 Connect the feedback arm assembly (Key 11) on to the shaft of the PS2
positioner using the socket set screw (Key 12). Refer to Figure 4D.

SIEMENS PS2 LINEAR MOUNTING INSTRUCTIONS:

NOTE: Refer to the appropriate valve and actuator instruction manuals for actuator
mounting instructions. These instructions assume that the actuator has already
been mounted to the valve but that the connecting block has yet to be installed.
The threads of the valve and actuator stems should each engage the threads of
the connecting block (Key 16) by a distance equal to that of the diameter of the
corresponding stem or greater.
1 Set the actuator to the upper bench set. Move the valve stem the required
travel, the valve stem should engage the actuator stem.
2 Place the connecting block on to the valve/actuator stems and align the
connecting block (Key 16) with the window of the actuator yoke. NOTE: The
connecting block should be parallel with the lower mounting pad of the
actuator yoke. Refer to Figure 5A.
Install any spacers (Key 19), connecting block bracket (Key 1), washers (Key
18), and cap screws (Key 17) as shown in Figure 5B. NOTE: The cap screws
(Key 17) should be centered in the connecting block mounting bracket. The
sliding pin assembly and sliding pin slot of the connecting block bracket should
be on the right hand side of the actuator. Refer to Table 3 for actuator sizes
that require connecting block spacers (Key 19).
