Description
The 4320 wireless position monitor is a true
linkage−less non−contacting wireless position
transmitter and limit switch. It is a rugged
measurement device that provides a precise
wireless feedback signal to indicate equipment
position with a percent (%) of span plus on/off
indication. The 4320 can be used to monitor
equipment such as valves, sliding−stem regulators,
displacement and float level sensors, and relief
valves. It is designed to be simple to use, compact,
and easily mounted.
The wireless position monitor periodically reads the
position of a measured device and transmits that
data over a wireless network. The transmitted data
includes the percent of span value, two limit switch
status indications, internal device temperature, and
power module voltage. It also checks for
configuration and service instructions from host
systems such as distributed control systems (DCS),
asset management systems (AMS), and supervisory
control and data acquisition (SCADA) systems.
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.
Feedback 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.
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.

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 10.0 and
above.
