The Manual
This manual will help you set up your SITRANS LR 460 for optimum performance.
SITRANS LR 460 is available in two versions (HART or PROFIBUS PA), and the manual is
in three parts:
Part I: information common to both versions
• introduction to LR 460
• specifications
• installation
•wiring
Part II: SITRANS LR 460 4-20 mA version
• 4-20 mA Quick Setup
• local operation using handheld programmer
• LCD menu charts
• HART communications
Part III: SITRANS LR 460 PROFIBUS PA version:
• PROFIBUS PA Quick Setup
• remote operation
•PAprofile
•PADataMaps
Appendices provide further information common to both models:
•
Appendix A: Parameter Descriptions
• Appendix B: Technical Reference
• Appendix C: Troubleshooting
• Appendix D: Maintenance
• Appendix E: Software Revision History
We always welcome suggestions and comments about manual content, design, and
accessibility. Please direct your comments to t[email protected]om.

Application Examples
The application example used in this manual illustrates a typical installation using
SITRANS LR 460. Because there is often a range of ways to approach an application,
other configurations may also apply. If the example does not apply to your application,
check the applicable parameter reference for the available options.
If you require more information, please contact your Siemens Milltronics representative.

Abbreviations and Identifications
Note: 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.
WARNING: Changes or modifications not expressly approved by
Siemens Milltronics could void the user’s authority to operate the
equipment.

SITRANS LR 460
SITRANS LR 460
SITRANS LR 460 is a long-range FMCW radar level transmitter for level measurement of
solids. It can be used in high pressure applications or applications requiring gas safety
approvals. The Easy Aimer design makes it easy to set up the device even in conditions of
extreme dust. The narrow antenna beam creates a sharp emission cone, which makes the
LR 460 quite insensitive to vessel interferences.
