SITRANS LR 460

SITRANS LR 460 is a 4-wire 24 GHz FMCW (Frequency Modulated/Continuous Wave) radar level transmitter with advanced signal processing for continuous monitoring of solids up to 100 meters. It is ideal for extreme dust and difficult applications. The Easy Aimer design makes it easy to install the device and orient the signal towards the material angle of repose. The high frequency signal creates a narrow emission cone, which makes the LR 460 quite insensitive to vessel interferences.

SITRANS LR 460

SITRANS LR 460 is available with an optional air purge connection for cleaning the interior of the antenna.

Programming

SITRANS LR 460 carries out its level measurement function according to the set of built-in parameter tables. You can make parameter changes via the Siemens Milltronics handheld programmer, a PC running SIMATIC PDM or a HART handheld communicator.

Approvals and Certificates

SITRANS LR 460 is available with General Purpose approval, or approval for hazardous areas containing dust. For details see

Approvals

on page 10.

System Implementation

SITRANS LR 460 supports HART communication protocol, or PROFIBUS PA (optional), and SIMATIC PDM software.

Key considerations

• Correct location is critical to a successful application.

• Avoid reflective interference from vessel walls and obstructions by following the guidelines below.

Nozzle design

• Bottom edge of horn must project from nozzle.

• Nozzle must allow adequate clearance to allow positioning if LR 460 has to be at an angle so that emission cone perpendicular to material surface.

Min. clearance: 10 mm (0.4")

Nozzle location

• Locate antenna at least 1 meter away from side wall.

• Keep emission cone free of interference from ladders, pipes, I-beams or filling streams.

• Make allowance for beam spread to avoid interference with the emission cone.

Device orientation

• Align the antenna so that the radar cone is perpendicular to the surface of the monitored material, if possible.

Installation in vessel with obstructions

Polarization Reference Point

Obstructions such as ladders, pipes, or the fill path, can cause false reflections. To avoid this, use the Polarization Reference Point to orient the device.

• A small center punch mark provides a polarization reference point.

• To get the best signal, rotate the device till the Polarization Reference Point either faces towards the obstruction, or faces away from the obstruction (at 180 degrees).

Note: the device can be rotated through 360

Air Purging System (Optional)

For more frequent cleaning, a purging system can be installed between the flange and the horn antenna. The system provides an 1/8" inlet (female thread) on the flange where cooling air or cleaning fluid passes through the flange and exits the inside of the horn to clean it. The customer will supply the purging medium by a manual or automatic valve system.

This option is only available with the universal flange for purging shown on page 17.

Notes:

• The Air Purge feature should not be activated with a dust cap in place.

• Purge duration, pressure, and interval, will vary with each application. It is the user’s responsibility to determine the requirements depending on the application and cleaning required.

• Short duration bursts of high pressure provide more effective cleaning than continuous low pressure air.

• Some dust particles are highly abrasive and can be drawn into the inside of the horn during purge cleaning, damaging the internal PTFE emitter of the antenna. A replacement kit is available from your local Siemens Milltronics representative.

• It is the customer’s responsibility to ensure that any vacuum or pressure in the measured vessel is maintained, considering the hole that passes through the process connection and SITRANS LR 460 antenna system.

• The purge connection is closed by the manufacturer, using a 1/8" plug.

• When the plug is removed to connect a purging system, the operator is responsible for ensuring that the purging circuit conforms to "Ex" requirements:

Optional Dust Cap

Note: The dust cap must be removed before using the Air Purge feature (see

The dust cap fits onto the end of the horn and prevents the buildup of dust and other process material inside the horn.

• It is particularly useful for applications in areas of high humidity, or with bulk solids with a high moisture content.

• Two sizes are available, to fit the standard 3" and 4" horns.

3.5.6. TVT (Auto False Echo Suppression) setup

Note: If the Reform parameter has been used to reshape the echo profile, Auto

False Echo Suppression must be re-enabled, to relearn the TVT curve

SITRANS LR 460 first learns the echo profile. Then the learned profile, or part of it, is used to screen out false echoes. (See Auto False-Echo Suppression on page 73 for a more detailed explanation.)

To use Auto False Echo Suppression via SIMATIC PDM:

a. Determine Range (the distance within which the learned TVT will

replace the default TVT). Measure the actual distance from the antenna reference point to the material surface using a rope or tape measure, and make allowances for the actual location of the LR 460.

Subtract 2 m (6.56 ft) from this distance, and use the resulting value. b. Open the menu Device – Auto False Echo Suppression. c. Enter the value for Range and click Set Range. d. Click Learn. The On and Off buttons disappear while the new curve

is being learned. e. When the buttons reappear, click Close. Auto TVT is now on, and the

learned TVT curve will be used. f. To turn Auto False Echo Suppression off or on, reopen menu Device

– Auto TVT and click On or Off.

Appendix A: Technical Reference

Principles of Operation

SITRANS LR 460 is a long range FMCW (Frequency Modulated Continuous Wave) radar transmitter. Radar level measurement uses the time of flight principle to determine distance to a material surface.

FMCW radar transmits a continuous wave. The frequency of the wave is constantly increasing: this is known as the sweep. By the time the first part of the wave has been reflected off the target and returned to the device, the part of the wave that is just being emitted is at a higher frequency. The difference in frequency between the transmitted and received signals is proportional to time of flight.

Electromagnetic wave propagation is virtually unaffected by temperature or pressure changes, or by changes in the vapor or dust levels inside a vessel.

SITRANS LR 460 consists of an enclosed electronic component coupled to an antenna and process connection. The electronic component generates an electromagnetic signal from 24.2 GHz to 25.2 GHz that is directed to the antenna.

The signal is emitted from the antenna, and the reflected echoes are digitally converted to an echo profile. The profile is analyzed to determine the distance from the material surface to the reference point on the instrument. This distance is used as a basis for the display of material level and output.

Measurement Response

The measurement response (response rate) limits the maximum rate at which the display and output respond to changes in the measurement. Once the real process fill/ empty rate (m/s) is established, a response rate can be selected that is slightly higher than the application rate. The response rate automatically adjusts the filters that affect the output response rate.

A: Technical Reference

There are three preset options: slow, medium, and fast.

Parameters

Values

If none of the preset options is satisfactory, the filters can be adjusted individually.

You will see the echo profile, the Time Varying Threshold (TVT), and a vertical line indicating the distance from the sensor to the echo selected.

Echo strength is indicated on the Profile (dB) vertical axis. The distance shown on the horizontal axis is the distance from the sensor to the target.

Time Varying Threshold (TVT)

The TVT is a threshold curve used to detect the presence of significant echoes. See

Page 79

False Echoes

False echoes can appear during the receive cycle. They can be caused by interference with the emission cone, or by internal impediments like a ladder rung, and are usually indicated by an incorrect high level reading.

You can rotate the device to minimize false echoes. See page 14 for details.

Polarization Reference Point

Auto False-Echo Suppression

Note: If possible, rotate the instrument before using Auto False-Echo Suppression, to

lower the amplitude of false echoes.

The TVT adjustment parameters allow you to manipulate the TVT (Time Varying Threshold), so that SITRANS LR 460 will ignore false echoes.

The default TVT hovers above the echo profile, and effectively screens out small false echoes. But if an obstruction is causing a large echo before the material level echo, that echo will rise above the default TVT.

1. Set Auto False-Echo Suppression to Learn. The instrument learns the echo profile at that moment

. The new TVT follows the echo profile, so that nothing rises above it.

2. Set Auto False Echo Suppression Distance so that the learned TVT will be used in the area of the false echoes, which will not rise above it. From that point on the default TVT will be used. The material level echo rises above this, and is selected as the true echo.

See page 58 for examples of the echo profile before and after using Auto False-Echo Suppression.

Set Auto False-Echo Suppression to Learn when the material level is substantially lower than process full level (ideally when the vessel is empty or almost empty).

7ML19985JM01 SITRANS LR 460 – INSTRUCTION MANUAL Page A-73

Page 80

Near Range (Blanking)

Note: Auto False-Echo Suppression is generally recommended in preference to using

Near Range.

Near Range allows you to set a distance in front of the antenna, within which any echoes will be ignored.

A: Technical Reference

Echo confidence

Echo confidence is an internally generated numeric rating given to an echo based on its relative strength, area, and height.

Loss of Echo (LOE)

A loss of echo (LOE) occurs when the calculated measurement is judged to be unreliable because the echo confidence value has dropped below the echo confidence threshold. The LOE timer starts running, and if the LOE condition persists beyond ten minutes (the time limit set by the LOE timer) the Unreliable Echo indicator replaces the Reliable Echo indicator.

Reliable Echo indicator Unreliable Echo indicator

While LOE is pending the x flashes, alternating with the two horizontal bars. When LOE becomes active, the x becomes solid and the auxiliary display shows fault code S: 0.

Upon receiving a reliable echo, the loss of echo condition is aborted, the Reliable Echo indicator reappears, and the reading returns to the current level.

LOE Timer

The LOE timer determines the time (in minutes) to elapse after the last valid reading before Fail-safe mode is activated. When the LOE timer expires, the material level to be reported is determined by Fail-safe Mode.

Fail-safe Mode

Fail-safe mode defines the reaction of the device if a Fail-safe condition is detected, so that the process will be put into a safe state in the event of a fault or failure. The particular application determines whether a high or low level is safe.

Page A-74 SITRANS LR 460 – INSTRUCTION MANUAL 7ML19985JM01

Page 81

The Fail-safe condition may be triggered by a loss of echo, a bad configuration, or certain device faults. You can select one of three possible values to be reported when a Fail-safe mode occurs:

• User-defined default value (Fail-safe value) used as output value.

• Store last valid output value.

• Calculated output value is incorrect.

Fail-safe value

The user-defined Fail-safe value allows you to enter the safest output value for your application.

Appendix E: HART Communications

Highway Addressable Remote Transducer, HART, is an industrial protocol that is superimposed on the 4-20 mA signal. It is an open standard, and full details about HART can be obtained from the HART Communication Foundation at www.hartcomm.org

SITRANS LR 460 can be configured over the HART network using either the HART Communicator 275 by Fisher-Rosemount, or a software package. There are a number of different software packages available. The recommended software package is the SIMATIC Process Device Manager (PDM) by Siemens.

HART Device Description (DD)

SITRANS LR 460 cannot be set up using a generic DD. The configuration software needs the HART Device Description for SITRANS LR 460.

You can download the HART DD for SITRANS LR 460 from the product page of our website. Go to: https://pia.khe.siemens.com/index.asp?Nr=14655

Older versions of the library will have to be updated in order to use all the features of SITRANS LR 460.

SIMATIC Process Device Manager (PDM)

This software package is designed to permit easy configuration, monitoring, and troubleshooting of HART devices. The HART DD for SITRANS LR 460 was written with SIMATIC PDM in mind and has been extensively tested with this software.

Appendix F: HART Information Structure

SITRANS LR 460 detects a material level via the sensor, and then processes that information to provide a measured value. The measured value is conveyed as a digital signal.

The LR 460 device design enables it to provide outputs to two different channels:

F; Profile structure HART

Block Model for recording and processing measured values

• a 4-20 mA channel

• a digital channel

The LR 460 follows a profile block model similar to a PROFIBUS Profile 3.01, Class B, PA device. The functions of the device are divided into blocks.

Information is recorded by the sensor, then passed through the Level Transducer Block to two independent Analog Input Function Blocks (AIFB1 and AIFB2).

The parameters used to configure the Function Blocks are standard profile parameters, following a convention similar to that used in the PROFIBUS Profile Structure. They can be modified by HART communications via PDM.

Analog Input Function Blocks AIFB1 and AIFB2

The two AIFBs are identical, but completely independent of each other. They utilize the output from the Level Transducer Block.

You set parameters for each AIFB in order for it to apply any required quality checks, scaling, and Fail-safe Operation selections.

AIFB1 The output of Analog Input Function Block 1 supplies the measured value and associated status information as a digital signal to two communication channels:

• via the mA Output Block to a 4 to 20 mA channel

• to the HART digital channel, as the HART Primary Variable. This can only be viewed via the HART digital channel.

AIFB2 The output of Analog Input Function Block 2 supplies the measured value and associated status information as a digital signal to the HART digital channel, as the HART Secondary Variable. This can only be viewed via the HART digital channel.

Description of the blocks
