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

 or Local Business Partner 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 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
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.
