Panel Mounting
Refer to figure 2.
Cut a hole in the panel surface according to the dimensions shown in figure 2. Remove the cap screws (key 252),
brackets (key 251), and vent assembly (key 28). Slide the controller or transmitter into the cutout and reattach the
brackets. Tighten the cap screw located in the center of each bracket to draw the case snugly and evenly against the
panel. Reinstall the vent unless a remote vent will be used.
Wall Mounting
Refer to figure 2.
Drill four holes in the wall using the dimensions shown in figure 2. In the bracket (key 251) are 8.7 mm (0.3438 inch)
diameter holes. Back out the cap screw located in the center of each bracket. (The screws are used for panel mounting
but are not required for wall mounting.) If tubing runs through the wall, drill holes in the wall to accommodate the
tubings. Figure 2 shows the pressure connection locations in the back of the case.
Mount the controller to the bracket using the four cap screws (key 252) provided. Attach the bracket to the wall, using
suitable screws or bolts.
Pipestand Mounting
Refer to figure 2.
Use a hammer and punch to knock out the blanks in the two holes indicated in the back view of figure 2. Attach the
spacer spools (key 228) and the mounting plate (key 213) to the controller with cap screws, lock washers, and nuts
(keys 215, 221, and 216). Attach the controller to a 2-inch (nominal) pipe with pipe clamps (key 250).
Actuator Mounting
Refer to figure 3.
Controllers specified for mounting on a control valve actuator are mounted at the factory. If the instrument is ordered
separately for installation on a control valve actuator, mount the instrument according to the following instructions.
Mounting parts for the different actuator types and sizes vary. Two typical actuator-mounting installations are shown
in figure 3; see the parts list for parts required for the specific actuator type and size involved.
Use a hammer and punch to knock out the blanks in the two holes indicated in the back view of figure 2. Attach the
spacer spools (key 228) and the mounting plate (key 213) to the controller with machine screws, lock washers, and
nuts (keys 215, 221, and 216).
Attach the mounting bracket to the actuator yoke with cap screws (key 222) and, if needed, spacer spools. On some
designs, the mounting bracket is attached to the actuator diaphragm casing rather than to the yoke.
