Guidelines for Mounting on Quarter‐Turn (Rotary‐Shaft) Actuators
The 4320 wireless position monitor can be mounted to any quarter‐turn (rotary‐shaft) actuator, as well as those that
comply with the NAMUR guidelines. A mounting bracket and associated hardware are required. Refer to figure 13.
Before mounting, verify the rotary motion is 45 to 90 degrees of rotation.
1. Attach the magnet assembly to the actuator shaft, as shown in figure 14. Position the magnet assembly 19.5 mm
(0.77 inch) away from the bottom base of the housing as measured from the base of the assembly to the base of the
housing. At mid‐travel, the flats on the magnet assembly must be parallel to the channel on the back of the 4320
housing, as shown in figure 15.
2. Install the mounting bracket on the actuator.
3. Attach the wireless position monitor to the mounting bracket using the 4 mounting bolts, as shown in figure 13.
4. Check for clearance between the magnet assembly and the positioner feedback slot.
5. Once the instrument is mounted perform the local interface calibration procedure, as described on page 28. Verify
that the magnet assembly is centered throughout the entire rotating range.
