7ML19985KE01 SITRANS LR260 (HART) – INSTRUCTION MANUAL Page 13mmmmmInstallationAir 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 14. 1• 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: for example, by fitting an NRV valve. 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 LR260 antenna system.Recommendation for effective cleaning Air Consumption(Flow rate versus applied pressure)Pressure: 90 to 110 psiAir Pressure Approx. inlet volume flow rate20 5 SCFM40 6 SCFMInlet flow: 10 SCFM 160 8 SCFM80 9 SCFM90 10 SCFM 1.

Page 76 SITRANS LR260 (HART) – INSTRUCTION MANUAL 7ML19985KE01mmmmmB: TroubleshootingAppendix B: TroubleshootingCommunication TroubleshootingGenerally:1. Check the following:• There is power at the instrument• The LCD shows the relevant data you are expecting• The device can be programmed using the hand programmer2. Verify that the wiring connections are correct.3. Check that the device address is correctly set.4. If you continue to experience problems, go to our website at: . www.siemens.com/processautomation, and check the FAQs for SITRANS LR260, or contact your local Siemens Milltronics representative.Specifically:1. If you try to set a SITRANS LR260 parameter via remote communications, but the parameter remains unchanged:• Some parameters can only be changed when the device is not scanning. Try putting the device in PROGRAM mode using the operating mode function.• Try setting the parameter from the keypad. (First make sure that the lock parameter [6.1] is set to the unlock value.)• The communications control parameter 5.2 must be set to Read/Write to allow you to write parameters to SITRANS LR260.2. If you see unanticipated displays, for example:• PROGRAM mode displayed instead of Measurement mode• the wrong parameter displayed in response to a command• a parameter displayed in response to no commandmake sure no infrared-capable device is close to SITRANS LR260. Any device with infrared capabilities (laptops, cell phones, PDAs) can cause interference which simulates a command to the SITRANS LR260, potentially causing it to switch modes or to change a parameter.3. If the operation is erratic, make sure the Hand Programmer is not being used at the same time as SIMATIC PDM.

7ML19985KE01 SITRANS LR260 (HART) – INSTRUCTION MANUAL Page 85mmmmmH: HART CommunicationsAppendix C: MaintenanceSITRANS LR260 requires no maintenance or cleaning under normal operating conditions. Under severe operating conditions, the horn 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. Unit Repair and Excluded LiabilityAll changes and repairs must be done by qualified personnel, and applicable safety regulations must be followed. Please note the following:• The user is responsible for all changes and repairs made to the device.• All new components must be provided by Siemens Milltronics Process Instruments Inc.• Restrict repair to faulty components only.• Do not re-use faulty components.

7ML19985KE01 SITRANS LR260 (HART) – INSTRUCTION MANUAL Page 89mmmmmD: Technical ReferenceFar RangeIn applications where the base of the vessel is conical or parabolic, a reliable echo may be available below the vessel empty distance, due to an indirect reflection path. Increasing the range extension to 30% or 40% can provide stable empty vessel readings.1Measurement ResponseThe 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. There are three preset options: slow, medium, and fast.mA OutputThe mA output is proportional to the level, in the range 4 to 20 mA. Generally, the output is set so that the output for 0% is 4 mA, and the output for 100% is 20 mA. 0 and 100% are percentages of the full-scale reading (m, cm, mm, ft, in). When SITRANS LR260 is put into PROGRAM mode it stops responding to the process. It stores the most recent measurement, and holds the associated readings and mA signal output. The instrument reverts to the parameter last addressed during the previous program session.1. On 30 m vessel, range extension cannot exceed 31.5 m.2.2.7.2. Fill Rate (FILL RATE/MIN)2.2.7.2.

Page 90 SITRANS LR260 (HART) – INSTRUCTION MANUAL 7ML19985KE01mmmmmD: Technical ReferenceWhen the instrument is returned to Measurement mode, the transceiver resumes operation. The reading and mA output default to the last measurement taken. The reading and associated outputs migrate to the current process level at a rate controlled by the response rate (2.2.7.1).If SITRANS LR260 is left in PROGRAM mode for 10 minutes without input, it automatically reverts to Measurement mode.DampingA damping filter smooths out the response to a sudden change in level. This is an exponential filter and the engineering unit is always in seconds. The setting can be modified in 2.2.4.3.2. Damping Filter.Damping example 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. If the LOE condition persists beyond the time limit set in 2.4.1. Fail-safe Timer the LCD displays the Maintenance Required icon, and the text region displays the fault code S: 0 and the text LOE.If two faults are present at the same time, the fault code, error text, and error icon for each fault are displayed alternately. For example, Loss of Echo and Fail-safe High. S: 0 LOE S: 52 FAIL-SAFEFail-safe ModeThe 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. 00.511.522.533.544.51234567Series 1 Ser i es2time constant = 2 secondsinput (level) change = 2 mIn 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.Level (m)Time (s)smoothed outputinput (level)

Parameter 3.14.1 is required to monitor the Internal Temperature. It gives you an excellent indication of how reliably the product will perform thermally when installed on your process vessel.3.14.1 also allows you to decide whether or not attention should be focussed on redesigning the installation. For example, if the internal temperature exceeds the maximum allowable limit, a sun shield or a longer nozzle may be required. Engineering will use this temperature reading (3.14.1) to gauge the extent of change required to the installation in order to provide a reliable thermal-operating zone for the SITRANS LR260.Note: The chart below is for guidance only: WARNING: Internal temperature must not exceed 80 °C (176 °F). 01020304050607080900 10 20 30 40 50 60 70 80 90 100 110 120 130 140 150 160flangetempera-tureprocesstemperatureAmbient Temperature (oC)Process Flange Surface Temperature (oC)Maximum Flange and Process Temperatures versus allowable ambient for flange adapter versions of SITRANS LR260• The chart does not represent every possible process connection arrangement.

7ML19985KE01 SITRANS LR260 (HART) – INSTRUCTION MANUAL Page 107mmmmmGlossaryGlossaryaccuracy: degree of conformity of a measure to a standard or a true value.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. There are four basic types of antenna in radar level measurement, horn, parabolic, rod, and waveguide.attenuation: a term used to denote a decrease in signal magnitude in transmission from one point to another. Attenuation may be expressed as a scalar ratio of the input magnitude to the output magnitude or in decibels.Auto False-Echo Suppression: a technique used to adjust the level of a TVT curve to avoid the reading of false echoes. (See TVT.)Auto False-Echo Suppression Distance: defines the endpoint of the TVT distance. (See TVT.) This is used in conjunction with auto false echo suppression.beam width: the angle diametrically subtended by the one-half power limits (-3 dB) of the microwave beam.beam spreading: the divergence of a beam as it travels through a medium. blanking: a blind zone extending away from the reference point plus any additional shield length.The instrument is programmed to ignore this zone.capacitance: the property of a system of conductors and dielectrics that permits the storage of electricity when potential differences exist between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference, and the unit is a Farad. confidence: describes the quality of an echo. HIgher values represent higher quality. Confidence threshold defines the minimum value.damping: term applied to the performance of an instrument to denote the manner in which the measurement settles to its steady indication after a change in the value of the level.dB (decibel): a unit used to measure the amplitude of signals.

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.range: distance between a transmitter and a target.range extension: the distance below the zero percent or empty point in a vessel. relative humidity: the ratio of the actual amount of moisture in the atmosphere to the maximum amount of moisture the atmosphere could hold (which varies depending on the air temperature).relative permittivity: see dielectric constant.repeatability: the closeness of agreement among repeated measurements of the same variable under the same conditions.shot: one transmit pulse or measurement.speed of light: the speed of electromagnetic waves (including microwave and light) in free space. Light speed is a constant 299, 792, 458 meters per second.stillpipe: a pipe that is mounted inside a vessel parallel to the vessel wall, and is open to the vessel at the bottom.
