Introduction
Scope of Manual
This instruction manual includes specifications, installation, initial setup, configuration, operation, troubleshooting,
and maintenance 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
The 4320 uses digital set point signals from a control host that causes the pneumatic output to deliver a discrete
(open/closed) control action to a valve actuator. Confirmation of the control command is provided with valve position
feedback, as shown in figure 2.
The input signal is received where the internal microprocessor runs a digital control algorithm resulting in an output
signal to the pneumatic output stage.
The pneumatic output stage is connected to supply pressure; using the set point action, air is directed to 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 one of the output ports on the spool valve will be
plugged.
For both monitoring and on/off control, 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. The valve continues to move until the correct position is attained.
The on/off control device can also be configured as a snapacting controller. In this configuration, 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 process being monitored generates the command to the controlled valve.
The 4320 uses position feedback to cause valve changes, as shown in figure 3. When the level in the storage tank
reaches a high level, the 4320 changes the inlet valve to closed, as a high level protection instrument. In this example,
the control system is alerted to changes in the level and valve, but the control action remains in the field instrument.
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.

Terminology
Local Interface—All 4320 wireless position monitors come standard with a Liquid Crystal Display (LCD) and two (2)
pushbuttons. The local interface provides the capability to setup and calibrate the monitor.
Magnet Assembly—This is the feedback component that is mounted directly to the valve stem. It supplies a magnetic
field that is sensed by the wireless position monitor. This component is typically part of most mounting kit assemblies.
Specifications
Specifications for the 4320 wireless position monitor are shown in table 1.
FCC Compliance
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of
the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to
radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in
which case the user will be required to correct the interference at his own expense.
This product is an FCC approved device. Changes or modifications to the 4320 wireless position monitor that are not
expressly approved by the party responsible for compliance may void your authority to operate the device.
WARNING
This product is intended for a specific temperature range and other application specifications. Failure to adhere to these
specification could result in the malfunction of the product, property damage, or personal injury.

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 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
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.
Installing Standard and Extended Life Power Modules
There are two battery-sourced power options, standard life and extended life power modules. Refer to the power
module warning labels, shown in figure 4, to determine which power module you have. Refer to figure 5 when
installing.

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
