  • Page 6: About The Sitrans Lu10

    About the SITRANS LU10 Notes: • The SITRANS LU10 is to be used only in the manner outlined in this instruction manual. • This product is intended for use in industrial areas. Operation of this equipment in a residential area may cause interference to several frequency based communications.
  • Page 7 The SITRANS LU10 is capable of monitoring wheat in 60 m (200 ft) high silos, acetone in 45 gallon barrels, or almost anything in between, in any combination. (Ensure the transducer selected for each vessel suits the material and measurement range required).

  • Page 8: Important Sitrans Lu10 Features

    While the SITRANS LU10 is typically used to monitor material level in open or closed vessels, any process which requires a distance measurement (within the system range) is a candidate for SITRANS LU10 application. Technical Reference Refer to Application Examples for detailed descriptions of a small sample of process measurement requirements to which the SITRANS LU10 may be applied.
  • Page 9 However, for demanding measurement requirements any operator programmable feature may be adjusted as desired. Following is a list of some of the features that make the SITRANS LU10 easy to program, yet versatile enough to handle complex level measurement requirements.

    The SITRANS LU10 can be used to monitor almost any process (within the temperature, measurement range, and chemical immunity capabilities of the system) where a distance measurement or determination of presence vs. lack of presence of an object is desired.

    Maintenance The SITRANS LU10 should require no maintenance, though good housekeeping practices in and around the area of the enclosure are recommended. Wipe out the area of the enclosure lid docking bay recess with a clean dry cloth (if necessary) before installing the programmer.

  • Page 102: Measurement Difficulties

    If a measurement difficulty occurs for greater than the Failsafe Timer (P070) setting, "LOE" is flashed alternately with the Reading display. Under certain conditions, a measurement difficulty may cause the SITRANS LU10 to "lock on" to a false echo and report a fixed or wrong Reading.
  • Page 103 Sometimes, material simply cannot be detected during vessel filling. In these cases, set up failsafe operation such that the SITRANS LU10 "anticipates" the rate of material level increase and adjusts the reported Reading accordingly. This operation is reliable, as long Technical Reference as when the dust (or foam) settles a valid echo can be received.

  • Page 105 (P852) to stabilize the "shot" mode used for the echo evaluation. Also, adjust the Short Shot Bias to increase (or decrease) the amount of preference given to short shot echoes over long shot echoes. Should a stable measurement still not be attainable, contact Siemens Milltronics or your local distributor. 7ML19985AN02 SITRANS LU10 –...
