Appendix C: Maintenance SITRANS LR560 requires no maintenance or cleaning under normal operating conditions. Under severe operating conditions, the antenna may require periodic cleaning. If cleaning becomes necessary: • Note the antenna material and the process medium, and select a cleaning solution that will not react adversely with either. • Remove the instrument from service and wipe the antenna clean using a cloth and suitable cleaning solution.
Appendix D: Technical Reference Note: Where a number follows the parameter name (for example, Algorithm (2.4.5.1.) this is the parameter access number via the local control buttons or the handheld programmer. See Parameter Reference on page 62 for a complete list of parameters. Principles of Operation SITRANS LR560 is a 2-wire 78 GHz FMCW (Frequency Modulated Continuous Wave) radar level transmitter for continuous monitoring of solids in vessels1).
Process Intelligence is able to differentiate between the true microwave reflections from the surface of the material and unwanted reflections being returned from obstructions such as seam welds or supports within a vessel. The result is repeatable, fast and reliable measurement. This technology was developed as result of field data gained over some twenty years from more than 1,000,000 installations in many industries around the world.
CLEF (Constrained Leading Edge Fit) • Uses the leading edge of the echo. • Is used mainly to process the echo from materials with a low dK value. In an almost empty flat-bottomed vessel, a low dK material may reflect an echo weaker than the echo from the vessel bottom. The echo profile shows these echoes merging. The device may then report a material level equal to or lower than empty The CLEF algorithm enables the device to report the level correctly.
CLEF Range (2.4.5.4.) Determines the level below which the CLEF algorithm will be used. Above this level the Center algorithm is used when Hybrid is selected in Position Detect (2.4.5.2.). CLEF Range is referenced from Far Range. sensor reference point CLEF Range Low Calibration Point Far Range Echo Threshold (2.4.5.3.) Confidence (2.4.7.1.) describes the quality of an echo. Higher values represent higher quality.
The material level should be below all known obstructions at the moment when Auto False Echo Suppression learns the echo profile. Ideally the vessel should be empty or almost empty, and if an agitator is present, it should be running. The device learns the echo profile over the whole measurement range and the TVT is shaped around all echoes present at that moment. Auto False Echo Suppression Range (2.4.8.2.) Auto False Echo Suppression Range specifies the range within which the learned TVT is applied.
Measurement Range Near Range (2.4.1.) Near Range programs SITRANS LR560 to ignore the zone in front of the antenna. The default blanking distance is 27.8 cm (0.91 ft) from the sensor reference point. Near Range allows you to increase the blanking value from its factory default. But Auto False Echo Suppression (2.4.8.1.) is generally recommended in preference to extending the blanking distance from factory values. Far Range (2.4.2.
Damping Filter Time Constant (2.5.8.1.) smooths out the response to a sudden change in level. This is an exponential filter and the engineering unit is always in seconds. Damping example time constant = 2 seconds input (level) change = 2 m Level (m) In 5 time constants the output rises exponentially: from 63.2% of the change in the first time constant, to almost 100% of the change by the end of the 5th time constant.
Fail-safe Behavior The purpose of the Fail-safe setting is to put the process into a safe mode of operation in the event of a fault or failure. The value to be reported in the event of a fault is selected so that a loss of power or loss of signal triggers the same response as an unsafe level. Fail-safe mode 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 is activated. Mode (2.5.9.1.
Temperature derating curve WARNINGS: • Never attempt to loosen, remove or disassemble process connection or instrument housing while vessel contents are under pressure. • This product is not intended for use as a safety device per Directive 97/23/EC. • The user is responsible for the selection of bolting and gasket materials which will fall within the limits of the flange and its intended use and which are suitable for the service conditions.
Appendix E: PROFIBUS PA Profile Structure PROFIBUS Level Device Design The device follows the profile block model and is implemented as a Profile 3.01, Class B, PA device. Standard profile parameters are used to program the level transducer block. Block Model The Block Model represents how measured values are recorded and processed. All data is viewed from the perspective of the DCS or PLC, so information from the sensor is an input.
Description of the blocks Transducer Block The figure below shows the signal flow of measured values from the sensor through the Transducer Block into the output value: • Primary Value (PV)1): Level (or Volume, if supported. LR560 does not support volume). • Secondary Value 1 (SV1): Level • Secondary Value 2 (SV2): Distance The Transducer Block implements all of the basic parameters of the PROFIBUS profile standard (illustrated in step 2 below).
2) Level Calibration is a linear transfer function that converts a sensor value to a level value.
Electronics temperature The Transducer Block monitors the internal temperature of the device electronics. A change in temperature can provide advance warning of a possible device failure, and allow for preventive maintenance. If a temperature limit is exceeded, the output value is unchanged but the output status changes. (The permitted limits correspond to those of the permitted ambient temperature.) Peak indicators1) allow you to check the maximum and minimum temperatures that have occurred.
3) 4) 5) 6) E: Profile structure mmmmm 7) Damping may be applied based on a user-selected time constant (see Damping on page 121 for details). The status of the input value received from the Transducer Block is checked. If the status is Bad, a Fail-safe condition occurs. The setting for Fail-safe Mode determines the Fail-safe value to be output. Mode (2.5.2.) allows the entire AI block to be overridden by a Manual Output value. See Simulate Output on page 53 for details.
PROFIBUS PA is an open industrial protocol. Full details about PROFIBUS PA can be obtained from PROFIBUS International at www.profibus.com.

A device for creating turbulence. algorithm: a prescribed set of well-defined rules or processes for the solution of a problem in a finite number of steps. ambient temperature: the temperature of the surrounding air that comes in contact with the enclosure of the device. antenna: an aerial which sends out and receives a signal in a specific direction.
dielectric constant (DK): the ability of a dielectric to store electrical potential energy under the influence of an electric field. Also known as Relative Permittivity. An increase in the dielectric constant is directly proportional to an increase in signal amplitude. The value is usually given relative to a vacuum /dry air: the dielectric constant of air is 11. echo: a signal reflected with sufficient magnitude and delay to be perceived as a signal distinct from the one directly transmitted.
PROFIBUS PA: one of the PROFIBUS family of protocols, specifically tailored for the needs of process industries (PA = Process Automation). pulse radar: a radar type that directly measures distance using short microwave pulses. Distance is determined by the return transit time. radar: radar is an acronym for RAdio Detection And Ranging. A device that radiates electromagnetic waves and utilizes the reflection of such waves from distant objects to determine their existence or position.
