Introduction
Scope of Manual
This instruction manual includes specifications, installation, basic setup and configuration, and maintenance and
troubleshooting information for the Fisher 4320 wireless position monitor.
This manual describes using the local interface to setup and calibrate the instrument.
Do not install, operate, or maintain a 4320 wireless position monitor without being fully trained and qualified in valve,
actuator, and accessory installation, operation, and maintenance. To avoid personal injury or property damage, it is
important to carefully read, understand, and follow all of the contents of this manual, including all safety cautions and
warnings. If you have any questions about these instructions, contact your Emerson Process Management sales office
before proceeding.
Description
Valve position is sensed through the non­contact, linkage­less feedback sensor. There are no moving linkages and the
4320 is physically separated from the valve stem through the use of a magnetic Hall effect sensor. A magnetic array is
mounted to the valve stem and the sensor is embedded in the 4320 housing. The sensor is electrically connected to
the printed wiring board to provide a travel feedback signal used in the control algorithm.
On/Off Control Option
The 4320 position monitor with on/off control option relays a digital set point generated by a control host to deliver a
discrete (open/closed) control action to a valve actuator. Valve position feedback provides confirmation of the control
action, as shown in figure 2. The valve command is converted to a pneumatic output signal. The pneumatic output is
connected to the supply pressure, and depending on set point, will either open or close the valve. The output can be
used with either air­to­open or air­to­close and supports both single and double­acting actuators. When a
single-acting actuator is used it is necessary to plug one of the output ports on the spool valve.
The on/off control device can also be configured as a snap­acting controller. In this configuration, there is no feedback
signal for the controlled equipment. The state of the monitored process triggers a command to the controlled valve.
The control system is alerted to changes in the process and the valve command, but the control action remains in the
field instrument. The 4320 uses the position signal, switch thresholds, and snap-control mode setting to decide when
to open or close the valve. For example, in figure 3, when a high level in the storage tank is reached, the 4320 closes
the inlet valve. In direct­acting snap, high or open trip on the input causes the controlled valve to open, and low/closed
trip on the input causes the controlled valve to close. In reverse­acting snap, high/open trip causes the controlled valve
to close, and low/closed trip causes the controlled valve to open.

Installation
WARNING
Before mounting the 4320 wireless position monitor:
D Always wear protective clothing, gloves, and eyewear when performing any installation procedures to avoid personal
injury or property damage.
D If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this
instruction manual.
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
WARNING
The 4320 power module contains two primary lithium­thionyl chloride batteries. Under normal conditions of use, the
battery materials are self­contained and are not reactive as long as the batteries and power module integrity are
maintained. Care should be taken to prevent mechanical, electrical, or thermal damage. DO NOT recharge, short-circuit,
disassemble, heat, or expose the power module to water. The batteries contain flammable materials and performing any of
the above actions could cause them to become damaged, ignite, or explode, resulting in personal injury or property
damage. Observe all warnings included with the power module before installing, operating, storing, or shipping the 4320
position monitor.
Personal injury and property damage can result from fire or explosion if the power module is subjected to heat above
100_C (212_F). Power modules should be stored in a cool, dry and ventilated area; for maximum life, storage should not
exceed 30_C (86_F).
CAUTION
When installing components, proper means of electrostatic discharge protection is required. Failure to use a grounding
strap, or other means of electrostatic discharge protection can result in damage to the electronics.
WARNING
To avoid static discharge do not rub or clean the antenna with solvents.
The 4320 has two available power sources; a battery-sourced power module, or an external power source.
Note
A 4320 powered by a battery-sourced power module cannot be converted to a 4320 powered by an external power source. The
housing and electronics are not the same for a 4320 powered by a battery-sourced power module and a 4320 powered by an
external power source.

STANDARD LIFE POWER MODULE
GE57655X012
EXTENDED LIFE POWER MODULE
Note
Default configuration is for a standard power module. If installing the extended life power module you must change the
configuration. Incorrect power module configuration will affect remaining days of life calculations. If using the Field
Communicator go to Configure, Manual Setup, Power Module, Reset Module Data. In AMS Device Manager go to Configure, Manual
Setup and select Reset Power Module Variables from the Power tab.
To install the power module:
1. Loosen the two instrument screws and open the cover.
2. Align the power module over the four banana plug connectors and insert on the main board.
3. Insert the four self tapping screws into the corresponding female receptors on the cover/main board assembly and
tighten to a torque of 0.282 N•m (2.5 lbf•in) to ensure that the power module is secured properly.
4. If you are replacing the power module see the additional steps to reset the power module remaining life counter, in
the Resetting Power Module Variables procedure found on page 63.
5. Close the cover and tighten the instrument cover screws to a torque of 5.6 to 6.7 N•m (50 to 60 lbf•in).

Refer to figure 6 when installing the wiring.
1. Loosen the two instrument screws and open the cover.
WARNING
Select a cable gland that is rated for the environment of use (such as hazardous area, ingress protection and temperature).
Failure to use properly rated cable glands can result in personal injury or property damage from fire or explosion.
When installing the cable gland or conduit fitting minimize the amount of wires remaining in the housing cavity so they do
not get compressed or damaged when closing the cover in step 7.
2. Insert a user-supplied cable gland or conduit fitting into the housing.
3. Insert the wires through the cable gland/conduit fitting.
4. Connect the wires to the connections as shown in figure 6. The terminals and electronics connections are
polarity-insensitive; ie., you can connect the positive or negative wire to either terminal screw.
5. As shown in figure 6, a ground terminal is available for connecting a safety ground. Make connections to this
terminal following national and local codes and plant standards.
6. Tighten the wiring terminal screws.
7. Close the cover and tighten the instrument cover screws to a torque of 5.6 to 6.7 N•m (50 to 60 lbf•in).

Network Setup
The 4320 should have wireless network parameters configured prior to becoming part of a wireless network. All
WirelessHART devices within a network have two network parameters that are the same; the Network ID and the Join
Key.
The 4320 is shipped with a pre‐configured Network ID of 1229 and a Join Key which is set to all zeros. Prior to being
installed these should be set to match the other devices on the network. These configuration changes can be made
using a 475 or 375 Field Communicator, AMS Wireless Configurator, or AMS Device Manager 10.5 and above.
Note
When the 1420 or other WirelessHART gateway is configured in an advanced security mode each device is required to have an
individual join key.
Using the Field Communicator
1. Verify the Field Communicator has a device description (DD) loaded for the 4320 Device Revision 4 (DD Revision 1
or later).

Valve / Actuator Mounting
If ordered as a part of a control valve assembly, the factory will mount the wireless position monitor on the actuator
and calibrate the instrument. If you purchased the wireless position monitor separately, you will need a mounting kit
to mount the wireless position monitor on the actuator. The following procedures are general guidelines you 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.
Note
All mounting materials should be non-ferrous. Ferrous materials are magnetic and may affect feedback.
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 assemblies.
CAUTION
General Guidelines for use of High Power Magnets with Position Monitoring Instruments
Use of high power magnets in close proximity to any position monitoring instrument which is operating a process should
be avoided. Regardless of the model, high power magnets can affect feedback accuracy. Technicians should avoid the use
of high power magnets in close proximity with any position monitoring instrument.
Use of Magnetic Tools with the 4320
D Magnetic Tip Screw Drivers – Magnetic tip screw drivers can be used to work on the 4320.
However, they should not be brought in close proximity to the magnet assembly (located
at the back of the instrument) during process operations.
Note
As a general rule, do not use less than 50% of the magnet assembly for full travel measurement. Performance will decrease as the
assembly is increasingly subranged.
The linear magnet assemblies 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 11.
The linear magnet assemblies 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:
D Linear or sliding‐stem actuators with up to 210 mm (8.25 inch) travel
D Rotary actuators with travel up to 90 degrees
D Device-specific applications for rotary actuators requiring 13 to 30 degree rotation

Sliding‐Stem (Linear) Actuators (e.g. Fisher 667)
Before mounting, verify that linear travel is greater than one‐half and not more than the maximum recommended
travel of the feedback kit.
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 assembly that is shorter than the physical travel of the actuator. Loss of control will result from the
magnet assembly moving outside the range of the index mark in the feedback slot of the 4320 housing.
3. Center the magnet assembly 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 assembly bolt holes to the base of the housing (see figure 13).
4. Align the magnet assembly as shown in figure 13.
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 14.
7. Once the instrument is mounted perform the local interface calibration procedure, as described on page 31. Verify
the magnet assembly position through the entire travel range before putting into service.

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 15.
Before mounting, verify the rotary motion is 45 to 90 degrees of rotation.
1. Stroke the actuator to one end of its travel.
2. Attach the magnet assembly to the actuator shaft, as shown in figure 16. 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. If the actuator is stroked all the way to the left or counterclockwise, attach the magnet assembly so it
points to the antenna (upper left corner of the instrument). If the actuator is stroked all the way to the right or
clockwise, attach the magnet assembly so it points to the upper right corner of the instrument. See figure 17.
Note
When the actuator is at its travel limits the magnetic array must always be at a 45 degree angle, regardless of the orientation of the
4320.

5.
6.
Install the mounting bracket on the actuator.
Attach the wireless position monitor to the mounting bracket using the 4 mounting bolts, as shown in figure 15.
Check for clearance between the magnet assembly and the positioner feedback slot.
Stroke the actuator and make sure that the magnet assembly is centered in the slot throughout the entire range of
rotation.
7. Once the instrument is mounted perform the local interface calibration procedure, as described on page 31. Verify
that the magnet assembly remains centered throughout the entire rotating range.

Pneumatic Hookup Procedures for On/Off Control Option
WARNING
To avoid personal injury or property damage resulting from bursting of parts, do not exceed maximum supply pressure.
Personal injury or property damage may result from fire or explosion if natural gas is used as the supply medium and
appropriate preventive measures are not taken. Preventive measures may include, but are not limited to, one or more of
the following: Remote venting of the unit, re‐evaluating the hazardous area classification, ensuring adequate ventilation,
and the removal of any ignition sources. For information on remote venting of this controller, refer to page 26.
Severe personal injury or property damage may occur from an uncontrolled process if the instrument supply medium is not
clean, dry, oil‐free, and noncorrosive. While use and regular maintenance of a filter that removes particles larger than 40
micrometers in diameter will suffice in most applications, check with an Emerson Process Management field office and
industry instrument air quality standards for use with corrosive air or if you are unsure about the amount of air filtration or
filter maintenance.
WARNING
When using natural gas as the supply medium the following also applies:
D When disconnecting any of the pneumatic connections or any pressure retaining part, natural gas will seep from the
unit and any connected equipment into the surrounding atmosphere. Personal injury or property damage may result if
natural gas is used as the supply medium and appropriate preventive measures are not taken. Preventive measures
may include, but are not limited to, one or more of the following: ensuring adequate ventilation and the removal of any
ignition sources.
Supply pressure must be clean, dry, air that meets the requirements of ISA Standard 7.0.01.
Alternatively, natural gas must be clean, dry, oil-free, and noncorrosive. H2S content should not exceed 20 ppm.
A maximum 40 micrometer particle size in the air system is acceptable. Further filtration down to 5 micrometer
particle size is recommended. Lubricant content is not to exceed 1 ppm weight (w/w) or volume (v/v) basis.
Condensation in the air supply should be minimized.
Use of a 67CFR filter regulator with standard 5 micrometer filter, or equivalent, to filter and regulate supply air should
suffice in most applications. The 67CFR filter regulator can be integrally mounted with the position monitor. Supply
connections are 1/4 NPT.
Prior to connecting the supply air to the spool valve, flush the system to remove any debris or contaminates.
4-Way Spool Valves
The spool valve is a 5 port, 4-way valve driven by an internally mounted pilot. Refer to figure 18 for spool valve supply
port and work ports locations and installation options.
CAUTION
Failure to install the supplied vents in the exhaust ports (ports 3 and 5) can result in damage to the seals.
24
Instruction Manual
4320 Position Monitor
D103621X012
April 2014
Never plug, block or restrict port 5 as any blockage or restriction may cause an internal pressure build­up inside the
enclosure, resulting in damage to the housing gasket.
Install the supplied vents in the exhaust ports (ports 3 and 5) to prevent debris from falling into the spool valve. Apply a
general purpose instant sealant to pipe threads and fittings. A flow control, such as a needle valve, may be used in Port
3, but should never be used in Port 5. To achieve IP67 protection, remote venting of ports 3 and 5 is required.

WARNING
This unit vents the supply medium into the surrounding atmosphere. When installing this unit in a non‐hazardous
(non‐classified) location in a confined area, with natural gas as the supply medium, you must remotely vent this unit to a
safe location. Failure to do so could result in personal injury or property damage from fire or explosion, and area
re‐classification.
When installing this unit in a hazardous (classified) location remote venting of the unit may be required, depending upon
the area classification, and as specified by the requirements of local, regional, and federal codes, rules and regulations.
Failure to do so when necessary could result in personal injury or property damage from fire or explosion, and area
re‐classification.
Vent line piping should comply with local and regional codes, should be as short as possible with a minimum inside
diameter of 12.7 mm (1/2‐inch), and few bends to reduce case pressure buildup.
To remotely vent the exhaust or to achieve IP67 protection, connect tubing and 1/4 NPT fittings to spool valve ports 3
and 5.
Communication Connections
A HART communicating device, such as a 475 or 375 Field Communicator, interfaces with the 4320 wireless position
monitor. Convenient termination points are located inside the front cover, as shown in figure 5. The
polarity-insensitive connection pins provide access to the Maintenance Port defined in the WirelessHART
specifications.
Wireless Communications
Devices in a WirelessHART network are time synchronized and send their data to the gateway at selectable update
rates. The update rates of the device have an effect on the number of devices that the gateway can service. For
example, if each device sent an update once per minute the gateway could support 100 devices.
Battery powered devices conserve energy by only sensing and transmitting data at the selectable update rate.
The faster the update rate the the shorter the life span of a power module. Figures 19, 20, 21, and 22 show the
correlation between power module life and update/sample rate, the number of sub-devices, temperature, and
actuations, respectively.

Continuous updates is the default communication method for the selected device variable; the device sends the data
to the gateway at every update period, whether the data has changed or not. However, the 4320 can also be
configured to allow position feedback sampling at faster than the default update rate and to send data only when the
measured variable has changed. This is useful in certain applications; for example, when used with relief valve

monitoring. When using the standard and extended life battery sourced power modules, sample rates can be set to as
fast as 0.5 second sampling. When using the external power option, the sampling rate is set to approximately 20 times
per second.
Note
Faster than publish rate sampling can only be configured when at least one of the three burst messages is being triggered.
Refer to Advanced Wireless Reporting (Report By Exception and Delayed Trigger Reporting) on page 39 for additional
information on faster sampling.

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 device to malfunction.
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 vice 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 calibration function of the local user interface can be locked out from the HART master for security purposes.
The two buttons on the LCD display (see figure 23) are used to activate the display when the LCD is in the sleep state
(blank or off). The buttons can be pressed alone or simultaneously. The Emerson logo will display when the LCD is
activated from a HART “squawk” command. Refer to Locate on page 58 for additional information.
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 23 for the local interface flow chart.
Identifying Firmware Revision
To identify the firmware revision when the device is in the sleep state, press the right button.

prompted press NEXT to return to the CALIBRATE menu.
Note
If it takes longer than 5 minutes to move the valve in each direction during Auto Calibration, Manual Calibration will need to be
performed. A normal auto calibration moves from Open > Closed > Open > Closed, and may take up to 20 minutes.
Manual Calibration
Press the right button to access MANUAL calibration with on/off control. Press the left button to access MANUAL
calibration with monitoring option.
Feedback— For on/off control press the left button for FEEDBACK calibration. For monitoring press SELECT.
This will allow you to select the first calibration point to be used, either 0% or 100%. Push the left button to select 100%
and the right button to select 0%. For monitoring only, the next display instructs you to set the valve or monitored
piece of equipment in either the 0 or 100% location, depending on the first calibration point chosen. Once set in
position, use the left button to toggle the recording position to MARKED. MARKED indicates that the location has been
recorded; UNMARKED indicates that position has not been recorded. After the first position has been MARKED press
NEXT to select the second calibration point (it will be be the opposite of the first calibration point). Use the left button
to toggle the recording position to MARKED. Press NEXT to enter the APPLY menu. Select YES to apply the changes.
When prompted press NEXT to return to the CALIBRATE menu.

return to the CALIBRATE menu.
When calibration is complete, the calibration status will be displayed:
SUCCESS—indicates that the calibration procedure was successful.
SPAN HI—indicates that a problem with the high end of travel or rotation was observed. Check the mounting and
magnet assembly placement and re‐attempt calibration.
SPAN LO—indicates that a problem with the low end of travel or rotation was observed. Check the mounting and
magnet assembly placement and re‐attempt calibration.
ERROR SPAN— indicates that the distance between the two marked endpoints was too small to provide a reliable
calibration. See table 5 on page 60 for troubleshooting help.
D Check the mounting and magnet assembly placement and re-attempt calibration.
D When using the rotary magnet assembly ensure that the magnet does not go perpendicular to the positioner
feedback slot.
FAILED— indicates that Auto Calibration failed, most likely because the valve failed to move or did not settle in time;
settle time for each position is 5 minutes.

Refer to figure 25 for the Configure menu tree.
Device configuration activities involve access to and the modification of information in the instrument that is not
published by the device, and therefore not cached in the gateway. When configuration is performed using a host that
talks to the device via the proxy (gateway), additional traffic is generated over the wireless network.
The Field Communicator or other portable host may be connected directly to the wired maintenance communication
port. All communications for configuration are then handled directly via the device's internal HART modem, bypassing
the device radio and the wireless network.

Enabling burst mode provides periodic publication of the configured messages to the gateway. The gateway maintains
a cache of this published information. It then acts as a proxy for all wireless devices by fulfilling routine host requests
using the latest data in its cache.
Note
It is recommended that you set burst mode to defaults during initial setup, and make any detailed adjustments to burst
configuration after the device is connected to an operating wireless network.
Burst mode is only supported over the wireless link. No burst transmissions are made over the wired Maintenance Port connection.
To select the basic message content, choose from Primary Variable, PV % Range and Loop Current, Dynamic Variables and
Current, Selected Device Variables, Additional Status, Emerson Specific, and Discrete Variables.
If Dynamic Variables and Current, Selected Device Variables, or Emerson Specific are chosen for basic content, you can
configure individual device variables in the message slots. Select variables from the available drop­down or selection
list that are relevant for your application.
Note
Variables marked with an asterisk (*) are not calculated by the device under the current installed options and/or structure
configuration. They should not be assigned for publication unless your host will not function correctly without them.
If an Emerson Gateway is in use, the 'Emerson-Specific' choice can be used. It combines the four Dynamic Variables and
the Additional Status in one message. However, it does not include the Loop Current or PV % Range variables. If the
control system requires PV % Range and Loop Current, make sure that these two variables are included in a message
configured for 'Selected Device Variables'.

Advanced Wireless Reporting (Report By Exception and Delayed Triggering)
Report By Exception (RBX) or Triggered Burst Mode allow you transmit data only when a change occurs. When a
triggered burst mode is enabled, a “trigger” variable is identified, and the data is sampled and published at a fast rate
when there is a significant change in the monitored trigger variable. A slower “default” rate is used when the trigger
conditions are not met. This feature results in lower energy consumption by the device, as there are fewer data
transmissions. You can define what is a “significant” change, as well as the values of the fast and default update rates.
To use this feature, configure one of the triggered burst modes. The “triggered” burst modes include: Windowed,
Rising, Falling, and On-Change trigger modes.
D Windowed— allows you to define a +/- boundary around the last sampled of the trigger variable. The trigger
variable must change by more than that “window” to trigger the fast update rate.
D Rising— the faster updates begin when the value of the trigger variable rises above the trigger level you select.
D Falling— the faster updates begin when the value of the trigger variable falls below the trigger level you select.
D On-Change— the whole burst message content is monitored for the slightest change. Any change initiates the
fast update rate.
Note
On-Change trigger mode is used for messages that contain discrete data. It should not be used on messages that contain floating
point data that dithers as a result of system noise or resolution limitations, such as the temperature variable.
The trigger variable varies with the selected message content. When “Selected Device Variables” is the general burst
message content, the variable that you assign to slot 0 in the Detailed Message Contents is the one monitored against
the trigger conditions. In most cases the assigned trigger variable is one of the process-related variables, i.e., one of
the 3 switch state signals. In other configurations of general message content, the trigger variable is predefined and
can be determined by viewing the configuration data.
Sensor Sample Rate—If any burst message is being triggered (is not in Continuous mode), a common sensor sample
rate is used for all data acquisition. For battery-powered devices, select a value between 0.5 seconds and the Triggered
Update Rate, in increments of 0.5 seconds.
Normally, the device wakes up to sample the data for a burst message in preparation for each scheduled publishing
event. In some applications it is possible to miss transitions that occur between the update intervals. Delayed
Triggering reduces the possibility of this occurring by defining a faster sample rate for monitoring. The sample rate
should be faster than the published rate. When a trigger condition is detected by the Delayed Triggering mechanism,
the time stamp and data are captured immediately. Publishing of the message is scheduled for the next available
publishing slot. For example; if you have the default update rate set for 1 minute, and the fast update rate set to 8
seconds, enabling Delayed Triggering with a 1/2 second sample rate allows you to detect a trigger event almost as
soon as it occurs. Without Delayed Triggering, transient events that occur during the 8 seconds interval are not
detected.

Identification
Tag—enter the HART tag for the instrument (up to 8 characters). The HART tag is the easiest way to distinguish
between instruments in a multi‐instrument environment. Use the HART tag to label instruments electronically
according to the requirements of your application. The tag you assign is automatically displayed when the Field
Communicator establishes contact with the 4320 at power‐up.

D103621X012
Long Tag—enter the HART Long Tag information (up to 32 characters).
Date—enter a date (mm/dd/yyyy) associated with configuration, commissioning, or maintenance history.
Description—enter a descriptor for the application with up to 16 characters. The descriptor provides a longer
user‐defined electronic label to assist with more specific instrument identification than is available with the HART tag.
Message—enter any message with up to 32 characters. Message provides the most specific user‐defined means for
identifying individual instruments in multi‐instrument environments.
Polling Address—used by the Host to identify a field device on the wired maintenance port (valid range is 0 through 63).
It has no significance on the wireless network and can only be edited at the maintenance port.
Structure
Snap Acting Control—when enabled, control valve action is derived from the position feedback or position being
monitored. The controlled valve is separate from the position being monitored by the device. (There is no feedback
signal for the controlled equipment.) The state of the switch monitoring the sensor generates the command to the
controlled equipment.
Direct-Acting Snap—high or open trip on the input causes the controlled valve to open. Low or closed trip on the
input causes the controlled valve to close.
Reverse-Acting Snap—high or open trip causes the controlled valve to close. Low or closed trip causes the controlled
valve to open.
Adjust switch thresholds and deadband for additional refinement of this behavior. If the device is a controller and not
in snap-acting mode, it may not report the Process state or use a latching switch mode.
When Snap-Acting Control is disabled, the device is in normal feedback control mode.
Note
Snap Acting Control is only available for units equipped with the on/off control option.
Latching Mode—when enabled, any change to the specified switch state (either opened/high or closed/low) will be
latched (or locked) in that condition until the latch mode is manually reset.
Note
Latching Mode can only be used in monitoring and snap-acting control applications. It is disabled in normal feedback control mode.
Application Mode—indicates sensor reporting mode: process feedback or valve travel feedback. A device with the
controller option installed must report valve travel when not in snap-acting mode.
Configure Structure—select whether the control mode is snap-acting, whether the switch state will latch when tripped,
and whether the position variable is labeled for valve or process reporting.

Operational Options
Valve Retry Enabled ­ when enabled, the device will automatically attempt to drive the controlled equipment back to
the set point 3 times before tripping the Valve Drift monitor. (On/off control only)
Dwell Tracking - when enabled provides increased resolution for dwell time measurements in monitor devices by
increasing the internal position-sampling rate to about 11 samples per second when a position change is detected.
(monitoring only)
Fast sampling ends when position changes remain below 1% for the Tracking Debounce Count. Enhanced Dwell
Tracking will work best when Hardware Triggering is also enabled.
When Dwell Tracking appears as an Operational Option, an additional menu item appears below it:
Tracking Debounce Count ­ the number of samples during which position change must be less than 1% of span before
terminating fast sampling for the enhanced dwell­time measurement.
Note
Operational Options is not available when the device is in snap acting mode.

Opened, Closed, Part-Open, Low, Mid, High, or Unknown (displayed for reference).
Opened/High Trip Point and Closed/Low Trip Point—user-defined threshold that determines when the monitored
condition is declared tripped.
Deadband—the amount of return travel inside the threshold that must occur before a tripped state is reset. Valid values
are from 0% to 20%. Default value is 5%.
Edit Parameters—sets the trip points and the deadband for the limit switches under procedural control to prevent
selections that could lead to indeterminate switch states.
D Mapping—allows configuration of the dynamic variable array. Select Set to Defaults to reset to the default values.
Warning Information— If your control system polls devices by using HART Command 3, either 'Dynamic Variables +
Current' must be configured as the content of one of the burst messages, or the Loop Current and the Device Variables
that you have mapped to Dynamic Variables must be included in the data being published. The 'Delayed Response'
mechanism will be used to acquire variables that are not being published, and your host may interpret that as a
communications failure.
D Fault Behavior (On/Off Control)
The device can be configured to enter a Fault State that attempts to drive the pneumatic output to the configured
“fault state”.
Note
When a fault condition is enabled and is active (i.e., in the fault state), the device does not act on the set point from the host. The
device controls the valve using the set point defined during configuration.
All Fault Conditions are disabled by default.

Calibration
WARNING
During calibration the valve will move full stroke. To avoid personal injury and property damage caused by the release of
pressure or process fluid, isolate the valve from the process and equalize pressure on both sides of the valve or bleed off the
process fluid.
Note
You cannot change the valve set point (i.e. open to closed) when the instrument is in snap-acting mode. This is because the
position signal from the monitored equipment is used to change the state of a different valve. Refer to figure 3 on page 3.
Manual calibration of the output is required when in snap-acting mode.
Calibration Date—indicates when the instrument was last calibrated.
Note
The Not Calibrated Alert replaces Calibration Date when it is active.
Sensor Calibration—allows you to run a calibration on the instrument. Follow the prompts on the Field Communicator
to run Auto or Manual Calibration.
Note
If it takes longer than 5 minutes to move the valve in each direction during Auto Calibration, Manual Calibration will need to be
performed. A normal auto calibration moves from Open > Closed > Open > Closed, and may take up to 20 minutes.
Output Assignment—allows you to associate the output ports with a stroke direction (open or close) by observing the
action during a stroke. This procedure is used to complete a controller calibration process if Manual Calibration was
used for the sensor, and is the only way to assign output sense in snap-acting mode.
Note
Output Assignment is only available for units equipped with the on/off control option.

Instruction Manual
D103621X012
Note
The 4320 wireless position monitor also includes a power module voltage warning and a critical power failure alert. These can be
viewed through the 1420 gateway web interface. Look under Monitor then Point Data and select your device from the available
HART tags.
There are two fields (true or false) that can be mapped into Modbus, OPC, or DeltaV:
D TAG.BATTERY_WARNING_GETTING_LOW and
D TAG.CRITICAL_POWER_FAILURE
BATTERY_WARNING_GETTING_LOW occurs at approximately 6.5 volts, at room temperature, and should be used to indicate that
maintenance should be performed or scheduled soon.
CRITICAL_POWER_FAILURE occurs at approximately 6 volts, at room temperature, and should be used to indicate that
maintenance should be performed or scheduled immediately.
For information on using Modbus or OPC with the 4320 wireless monitor refer to 4310/4320 Wireless Position Monitor OPC
System Integration Guide (D103530X012) or 4310/4320 Wireless Position Monitor Modbus System Integration Guide
(D103529X012), available from your Emerson Process Management sales office or at www.Fisher.com.
D Open or close stroke time indicates how long the on/off controller took to previously open or close the valve (not
available in snap-acting mode). Increased stroke time could suggest increased packing or bearing friction, loss of
motive-force, or trim clogging. Decreased stroke time could indicate the loss of process pressure or separated
linkage.
Refer to figure 25 and 26 for the Field Communicator menu trees.
In AMS Wireless Configurator or AMS Device Manager, go to Service Tools, Variables, then select the Valve tab to view
Last Close Stroke Time or Last Open Stroke Time and the Dwell Time in the current state, as shown in figure 31.
D Opened/high or closed/low dwell time indicates how much time has elapsed since the switch state last entered
opened/high or closed/low region. This can be used to determine when the valve last moved.
Transition Dwell provides the total elapsed time the valve was in the transition state ­ between limits. This was
initially implemented for safety relief valve monitoring applications to eliminate the need of calculating the
difference of timestamps sent to the control system host. This refers to the time the valve was not closed. In order
for this feature to report correctly you must first map to the Transition Dwell as a published variable. Go to
Configure, Manual Setup and click on the Wireless tab. Select View/Configure Message 0 (or whichever message is
publishing Selected Device Variable). Click on Modify, then set Transition Dwell as one of the published variables.
