should consider when mounting the wireless position
monitor. See the instructions that come with the
mounting kit for detailed information on mounting the
wireless position monitor to a specific actuator
model.
The feedback system for the 4320 wireless position
monitor utilizes a magnetic field for true linkage-less,
non-contacting position measurement. In order to
prevent inadvertent stem movement while the
instrument is in operation, magnetic tools (such as a
magnetic-tipped screwdriver) should not be used.
CAUTION
The magnet material has been
specifically chosen to provide a
long-term stable magnetic field.
However, as with any magnet, care
must be taken when handling the
magnet assembly. Another high
powered magnet placed in close
proximity (less than 25 mm) can cause
permanent damage. Potential sources
of damaging equipment include, but
are not limited to: transformers, DC
motors, stacking magnet arrays, and
magnetic tipped screwdrivers.
Note
As a general rule, do not use less than
50% of the magnet array for full travel
measurement. Performance will
decrease gradually as the array is
increasingly subranged.

Figure 4. Mounting—Sliding-Stem Magnet Array
The linear magnet arrays have a valid
travel range indicated by arrows
molded into the piece. This means that
the hall sensor (on the back of the
4320 housing) has to remain within
this range throughout the entire valve
travel. See figure 2.
The linear magnet arrays are
symmetrical. Either end may be up.
There are a variety of mounting brackets and kits
that are used to mount the 4320 to different
actuators. However, despite subtle differences in
fasteners, brackets, and connecting linkages, the
procedures for mounting can be categorized as
follows:
DLinear or sliding-stem actuators with up to
4 inch travel
DRotary actuators with travel up to 90 degrees.
See figure 3 for the different travel feedback magnet
assemblies.

Communications Connections
A HART communicating device, such as a 375 Field
Communicator, interfaces with the 4320 wireless
position monitor. Convenient termination points are
located inside the front cover. The connection pins
are not polarity sensitive. The instrument must be
powered before digital communication will
commence.
Basic Setup using the Local User
Interface
CAUTION
When accessing the pushbuttons or
terminals proper means of
electrostatic discharge protection is
required. Failure to provide
appropriate protection can cause the
valve to move, resulting in
valve/actuator instability.
The primary function of the local user interface is for
calibration. However, information for checking the
status of the device, as well as the connected
equipment or valve, is also available through the
local user interface.
Note
The valve must move from open to
closed, or vise versa, in order for the
wireless position monitor to be
calibrated. Attempting to calibrate the
device without moving the valve will
result in the action being discarded.
The operation of the device will be
unchanged.
The two buttons on the LCD display (see figure 9)
are used to activate the display when the LCD is in
the sleep state. The buttons can be pressed alone or
simultaneously. The Emerson logo will display when
the LCD is activated from a HART “squawk”
command.
When navigating the interface the left button is
generally used to “SELECT” or take an action, the
right button is used to go to the “NEXT” option. Refer
to figure 9 for the local interface flow chart.

DBurst Mode
Burst Mode—Enabling burst mode provides
continuous communication from the wireless position
monitor. Burst mode applies only to the transmission
of burst mode data and does not affect the way other
data is accessed.
Access to information in the instrument is normally
obtained through a wireless network or a 375 Field
Communicator. The field communicator or the
network may request any of the information that is
normally available, even while the instrument is in
burst mode. Between each burst mode transmission
sent by the instrument, a short pause allows the
Field Communicator or control system to initiate a
request. The instrument receives the request,
processes the response message, and then
continues “bursting” the burst mode data.
Burst Command—there are six burst commands;
Command 1, Command 2, Command 3, Command
9, Command 48 and Command 178.
DCommand 1 returns the Primary Variable
(PV) for the 4320
DCommand 3 returns the loop current,
Percent of Range, Close Trigger Status, Open
Trigger Status, and Temperature (outside of the
instrument).
DCommand 48 returns status about the
instruments operation.
Note
Commands 2 and 9 are not covered in
this manual. Command 178 is used
exclusively with the 1420 gateway for
efficiency.

Principle of Operation
The basic concept of the electronic positioner can be
understood by visualizing a magnet mounted to a
piece of equipment that either has a rotating motion
or sliding linear movement. The device has the
ability to detect position of the magnet and transmit
wirelessly the relative position. The 4320 wireless
position monitor is similar to a wired position
transmitter on a valve but without wires.
The 4320 is a communicating micro-processor
based instrument that includes the use of a hall
sensor to detect the relative position (or percent of
span) of a magnet that is attached to equipment
(e.g. process control valve; either automated or
manual). The 4320 is a battery powered device with
the power modules located on the inside of the
device. The primary means of communication is
wireless, conforming to the WirelessHART
communications standards. The device also
supports wired communication using the HARTR
protocol to connect to a handheld device, such as
the 375 Field Communicator. The handheld
connection is used for initial device configuration (i.e.
network set-up). The device includes a local user
interface (LCD display and two pushbuttons)
primarily used to calibrate or define the span of
position being measured. No ground point is
required. Device contains an internal patch antenna.
Maintenance
When replacing any of the components of the 4320
wireless position monitor the maintenance should be
performed in an instrument shop whenever possible.
WARNING
Before performing any maintenance
procedures on the 4320 wireless
position monitor:
