1. Attach the mounting bracket to the actuator.
2. Loosely attach the feedback pieces and magnet
assembly to the valve stem connector. Do not
tighten the fasteners because fine adjustment is
required.
CAUTION
Do not install a magnet array that is
shorter than the physical travel of the
actuator. Loss of control will result
from the magnet array moving outside
the range of the index mark in the
feedback slot of the 4310 housing.
3. Center the feedback array inside the retaining
slot 5.7 mm (0.22 inch) away from the bottom base
of the housing, as measured from the center of the
feedback array bolt holes to the base of the housing
(see figure 5).
4. Align the magnet array as shown in figure 5.
5. Tighten the fasteners.
6. Mount the wireless positioner monitor to the
mounting bracket, using the mounting bolts. Any of
the mounting holes may be used for linear actuators.
See figure 6.

7. Once the instrument is mounted perform the local
interface calibration procedure, as described on
page 12. Verify the feedback array position through
the entire range before putting into service.
Guidelines for Mounting on
Quarter−Turn (Rotary−Shaft) Actuators
The 4310 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 7.
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 8. 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
feedback array 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
4310 housing, as shown in figure 9.
2. Install the mounting bracket on the actuator.
