SITRANS LR 300.book Page 28 Monday, June 10, 2002 7:18 PM Rod Assembly Notes: Teflon paste (supplied) Optional Extension • If water or process fluids enter the connecting threads, this can cause reflections at the connection. These reflections will appear as false echoes. • Apply Teflon paste to the threads, and tighten slowly. Ensure that the rod sections mate securely with no gaps. Do not apply too much Teflon paste or the parts will not mate securely. • Do not use wrenches or pliers.
PAGE 31
SITRANS LR 300.book Page 29 Monday, June 10, 2002 7:18 PM If the mounting illustrated on page 28 is not suitable due to the minimum blanking requirements, consider the shielded rod or horn antenna options. Nozzles that are 200mm (8”) or larger in diameter provide excellent signal conditions. Under these conditions you can use the standard rod without extensions for nozzle lengths of up to 610mm (24”). Mounting: Threaded Rod Antenna You can use 1.5” or 2” threaded process connections.
PAGE 32
SITRANS LR 300.book Page 30 Monday, June 10, 2002 7:18 PM Mounting: Horn Antennas or Shielded Rod The end of the horn, or the end of the shield section, should protrude a minimum of 10mm (0.5”) to avoid interference with the nozzle. 10 mm (0.5") 10 mm (0.5") Mounting: Waveguide Antenna This option is recommended for products with εr lower than 3. See P655 on page 68 for the related propagation factor.
PAGE 33
SITRANS LR 300.book Page 31 Monday, June 10, 2002 7:18 PM Mounting: Stillpipe or Sidepipe This is an alternative to the waveguide antenna option, used for products with an εr less than 3 or for extremely turbulent or vortex conditions. This mounting arrangement can also be used to provide optimum signal conditions on foaming materials. Suitable pipe diameters are 50mm (2”) to 250mm (10”). A rod antenna or a horn antenna may be used.
PAGE 34
SITRANS LR 300.book Page 32 Monday, June 10, 2002 7:18 PM Mounting: Horn with Waveguide Extensions Use this combination if the nozzle is long and the diameter is small. For example, if the nozzle is 100mm (4”) in diameter and 460mm (18”) in length), the rod antenna is not suitable due to nozzle interference. Waveguide extensions are available in custom lengths. If the horn diameter is too large for the nozzle opening, you need to insert it from inside the vessel.

SITRANS LR 300.book Page 45 Monday, June 10, 2002 7:18 PM Operation Overview The SITRANS LR 300 is an advanced level-measuring device for liquids and slurries. Using advanced pulse radar technology, the device calculates material level by emitting a series of radar pulses and then analyzing their reflections. The device consists of an enclosed electronic component mounted to a flanged antenna component. The electronic component generates a 5.8 GHz (U.S.A. 6.
PAGE 48
SITRANS LR 300.book Page 46 Monday, June 10, 2002 7:18 PM Loss of Echo (LOE) A loss of echo (LOE) occurs when the calculated measurement is judged to be unreliable because the confidence (P805) is less than the threshold (P804). Refer to Operation Troubleshooting on page 92. If the LOE condition persists beyond the time limit set by the Fail-Safe timer (P070), the Confidence icon will change from full to partial: Operation mmmmm to The response to LOE is set by P072 and P219.
PAGE 49
SITRANS LR 300.book Page 47 Monday, June 10, 2002 7:18 PM Analog Output The SITRANS LR 300 can be programmed to provide an analog output (P200) of 4 to 20 mA, and for proportional or inverse span. Programming When the unit is put into PROGRAM mode, the analog output level holds its prior value unless the mA output function is the common output or HART is the communication protocol. Run P001 = 2 (space a.k.a.
PAGE 50
SITRANS LR 300.book Page 48 Monday, June 10, 2002 7:18 PM RUN/PROGRAM When you select PROGRAM mode, the SITRANS LR 300 stops responding to the process. It stores the most recent measurement, and holds the associated readings and mA signal output. The unit reverts to the parameter last addressed during the previous program session. When you select RUN mode, the transceiver resumes operation. The reading and mA output default to the last measurement taken.

SITRANS LR 300.book Page 78 Monday, June 10, 2002 7:18 PM P837 Auto False Echo Suppression (F = 1)1 Use P837 and P838 during start up, if possible. It works ideally if the tank is empty or at low levels. Only use this function if there is a minimum 2m distance from the radar unit to the material. The agitator should be running, if the vessel contains an agitator. Use this feature to adjust the TVT Curve height to ignore false echoes on the Echo Profile by placing the TVT above the current signal.
PAGE 81
SITRANS LR 300.book Page 79 Monday, June 10, 2002 7:18 PM Example After Auto False Echo Suppression TVT curve (Learned) Liquid level False echo If the SITRANS LR 300 displays a full level, or if the reading fluctuates between a high level and a correct level, set this parameter to elevate the TVT in this region and to desensitize the receiver from any ‘base noise’ caused by internal antenna reflections and/or nozzle echoes. Entry: 0 = Off (not used). 1 = Use Learned TVT.
PAGE 82
SITRANS LR 300.book Page 80 Monday, June 10, 2002 7:18 PM P838 Auto False Echo Suppression Distance (F = 1.0m) Defines the endpoint of the Learned TVT distance. Set this parameter with P837, as above. P839 TVT Hover Level (F = 40) Defines (in %) how high the TVT is placed above the profile, with respect to the largest echo. When the SITRANS LR 300 is located in the center of the vessel, this parameter may be reduced to prevent multiple echo detections.

SITRANS LR 300.book Page 122 Monday, June 10, 2002 7:18 PM Function Blocks – Analog Input The Analog Input (AI) function blocks produce the device outputs for Profibus. They utilize the outputs from the Level TB (PV, SV1, SV2, … SVn) and then apply any required scaling and quality checks. There are four AI blocks, which each use one of the TB outputs and modify it to produce the Level, Space, Distance and Volume OUT values. Note: These AI OUTs are not the same as the TB outputs available to the LCD.: .
