Introduction

Scope of Manual

This instruction manual includes specifications, installation, basic setup and configuration, and maintenance and
troubleshooting information for the Fisher 4320.

This manual describes using the local interface or a Field Communicator to setup and calibrate the instrument.

Do not install, operate, or maintain a Fisher 4320 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 sales office
proceeding.

or Local Business Partner before

Description

Valve position is sensed through the noncontact, linkageless 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 on/off controller 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
airtoopen or airtoclose and supports both single and doubleacting 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 snapacting 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 directacting 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 reverseacting 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:

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 lithiumthionyl chloride batteries. Under normal conditions of use, the
battery materials are selfcontained 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.

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.

Valve / Actuator Mounting

If ordered as a part of a control valve assembly, the factory will mount the 4320 on the actuator and calibrate it. If you
purchased the instrument separately, you will need a mounting kit to mount it on the actuator. The following
procedures are general guidelines you should consider when mounting the 4320. See the instructions that come with
the mounting kit for detailed information on mounting 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 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

Use of high power magnets in close proximity to this instrument should be avoided.

Use of Magnetic Tools

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 8.

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 10).

4. Align the magnet assembly as shown in figure 10.

5. Tighten the fasteners.

6. Mount the 4320 to the mounting bracket, using the mounting bolts. Any of the mounting holes may be used for
linear actuators. See figure 11.

7. Once the instrument is mounted perform the local interface calibration procedure, as described on page 27. 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 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 12.

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 13. 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 14.

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.

3. Install the mounting bracket on the actuator.

4. Attach the 4320 to the mounting bracket using the 4 mounting bolts, as shown in figure 12.

5. Check for clearance between the magnet assembly and the positioner feedback slot.

6. 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 27. 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 22.

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 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.

D The 4320 does not incorporate explosive fluid and/or process seals. Follow appropriate local, regional, and national,

codes for installation of these types of products when using natural gas as the supply medium.

CAUTION

Do not use sealing tape on pneumatic connections. This instrument contains small passages that may become obstructed
by detached sealing tape. Thread sealant paste should be used to seal and lubricate pneumatic threaded connections.

Supply pressure medium must be clean, dry, and noncorrosive and meet the requirements of ISA Standard 7.0.01 or
ISO 8573-1. 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 supply medium 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. 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 15 for spool valve supply
and work port 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.
