475 FIELD
COMMUNICATOR
OVERVIEW
The 475 Field Communicator includes a color LCD touch screen, a Lithium Ion battery
(Power Module), a SH3 processor, memory components, and integral communication
and measurement circuitry.
The 475 Field Communicator supports HART and F
OUNDATION
fieldbus devices, letting
you configure, maintain, or troubleshoot devices. When using the 475 Field
Communicator to communicate with devices, follow all standards and procedures
applicable to the location. Failure to comply may result in equipment damage and/or
personal injury. Be sure to understand and comply with the sections in this manual.
Device Interoperability
The 475 Field Communicator is designed to operate with a wide range of HART and
F
OUNDATION
fieldbus devices independent of device manufacturer. Device
interoperability is achieved through the Electronic Device Description Language
(EDDL) technology supported by the HART Communication Foundation and Fieldbus
Foundation.
Basic testing is performed on all device descriptions. Each device manufacturer is
asked to certify that they thoroughly tested their devices with the 475 Field
Communicator. If certification is not received, a warning message displays when you
attempt to communicate with an untested device. New device descriptions are
available from the Field Communicator Easy Upgrade Utility.
Working in a Hazardous Area
An Intrinsically Safe (IS-approved) 475 Field Communicator can be used in Zone 0
(FM and CSA only), Zone 1, or Zone 2,
for Group IIC, and Class I, Division 1 and
Division 2, Groups A, B, C, and D locations.
An IS-approved 475 Field Communicator may be connected to loops or segments that
are attached to equipment located in Zone 0, Zone 1, Zone 2,
for Group IIC; Zone 20,
Zone 21, Zone 22, and Class I, Division 1 and Division 2, Groups A, B, C, and D
locations.
IS-approved 475 Field Communicators are ordered with the KL option and have an
additional label on the back of the 475 that lists the approvals.
See Appendix B “Product Certifications” for more information about IS approvals and
installations.
CAUTION
You can install or remove the Li-Ion battery in a hazardous area environment.You
cannot charge the battery in this environment because the power supply/charger is not
IS-approved.
