Direct SITRANS LR260 so the horn antenna is pointed at an angle perpendicular to the material surface, if possible. (As a guide, aim the beam at a point approximately 2/3 of the way across the tank diameter.)3. When the desired position is reached, re-tighten the 5 bolts to 15-23 N m (11 to 17 Lbf-ft).Note: When the Easy Aimer ball is loosened, the device is free to tilt to a maximum of 30°.top clamping plate (upper socket)bottom clamping plate (lower socket)customer gasket as required [recommended thickness 1.5 to 1.8 mm (0.06 to 0.07")]customer mounting plate, as requiredø 4" (102 mm) min., central opening30° max.285 mm (11.22") 0.38" (10 mm)Easy Aimer ball locking boltsEasy Aimer](https://usermanual.wiki/Siemens-Canada-Siemens-Milltronics-Process-Instruments/LR260.USERS-MANUAL/User-Guide-875663-Page-18.png)

The settings can be modified locally via the Local User Interface (LUI) which consists of an LCD display and a handheld programmer. A Quick Start Wizard provides an easy step-by-step guide to help you configure the device for a simple application. There are two ways to access the wizard:•7-step Quick Start Wizard via the handheld programmer on page 28•4-step Quick Start Wizard via SIMATIC PDM on page 32For more complex setups, see Appendix E: Application Example on page 98, and for the complete range of parameters see Parameter Reference on page 42.Activating SITRANS LR260Power up the instrument.

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.](https://usermanual.wiki/Siemens-Canada-Siemens-Milltronics-Process-Instruments/LR260.USERS-MANUAL/User-Guide-875663-Page-82.png)

This “knowledge based” technique produces superior performance and reliability.Time Varying Threshold (TVT) CurvesA Time Varying Threshold (TVT) curve hovers above the echo profile to screen out unwanted reflections (false echoes). In most cases the material echo is the only one which rises above the default TVT curve. In a vessel with obstructions a large false echo may rise above the default TVT. The Auto False Echo Suppression feature (see below) can be used to screen it out.The device characterizes all echoes that rise above the TVT as potential good echoes. Each peak is assigned a rating based on its strength, area, height above the TVT, amongst other characteristics. The true echo is selected based on the setting for the Echo selection algorithm (2.2.4.1.1. Algorithm.).Echo LockIf the echo selected by Algorithm is within the Echo Lock window, the window is centered about the echo, which is used to derive the measurement. In radar applications, two measurement verification options are used:•Lock Off: SITRANS LR260 responds immediately to a new selected echo (within the restrictions set by the Maximum Fill / Empty Rate), but measurement reliability is affected.Echo Position DetectionThe echo position algorithm (2.2.4.1.2. Position) determines which point on the echo will be used to calculate the precise time of flight, and calculates the range using the calibrated propagation velocity (adjusted by a propagation factor, if necessary).
