    SITRANS Probe LU is now ready to operate. Using Auto False Echo Suppression If SITRANS Probe LU displays a false high level, or the reading is fluctuating between the correct level and a false high level, you can use the Auto False Echo Suppression TVT setup parameters to prevent false echo detection.

  • Page 28: Remote Operation Via Profibus Pa

    Remote operation via PROFIBUS PA SITRANS Probe LU (PROFIBUS PA) is a Class B, Profile Version 3.0, rev. 1, PA device. It supports Class 1 Master for cyclic and acyclic data exchange, and Class 2 for acyclic services. The full range of SITRANS Probe LU functions is available only over a PROFIBUS PA network.

  • Page 29: Configuration

    In the case of the Probe LU (PROFIBUS PA), the maximum PROFIBUS current is user- PROFIBUS Current Consumption selectable, and can be either 12, 13, 15, or 20 mA. (See page 79.) 7ML19985JB02 SITRANS Probe LU (PROFIBUS PA) – INSTRUCTION MANUAL Page 23...

  • Page 30: Cyclic Versus Acyclic Data

    Configuration information is only needed periodically and is set up as acyclic data. Cyclic Data When you configure SITRANS Probe LU on the PROFIBUS PA bus, there are two slots available for modules. Each of the slots has to have a module defined in it.

    Acyclic Data SITRANS Probe LU supports up to four simultaneous connections by a Class 2 Master (C2 connection). It supports one connection by a Class 1 Master (C1 connection). In order for a Class 1 Master to read parameters from an instrument, it needs to know the slot and absolute index of the parameter.

  • Page 41: Appendix A: Technical References

    The transducer emits a series of ultrasonic pulses: each pulse is reflected as an echo from the material and sensed by the transducer. The echo is processed by SITRANS Probe LU, using Siemens proven Sonic Intelligence techniques. Filtering is applied to help discriminate between the true echo from the material and false echoes from acoustic and electrical noise, and agitator blades in motion.

  • Page 42: Loss Of Echo (Loe)

    • When Echo Lock is Off, SITRANS Probe LU responds immediately to a new measurement (within the restrictions set by the Maximum Fill / Empty Rate). However, measurement reliability is affected. • When Maximum Verification or Material Agitator is selected, a new measurement outside the Echo Lock Window must meet the sampling criteria.

  • Page 43: Failsafe Value

    Auto False-Echo Suppression The TVT adjustment parameters allow you to set a TVT (Time Varying Threshold) curve, so that SITRANS Probe LU will ignore false echoes. The default TVT curve hovers above the echo profile, and effectively screens out small false echoes.
  • Page 44 Distance (meters) Turn on Auto False-Echo Suppression when the material level is substantially lower than process full level (ideally when the tank is empty or almost empty). Page 38 SITRANS Probe LU (PROFIBUS PA) – INSTRUCTION MANUAL 7ML19985JB02...

  • Page 45: Open Channel Monitoring (Ocm)

    Open Channel Monitoring (OCM) OCM converts a level reading (head) into a flow value using a linear algorithm. SITRANS Probe LU can convert a head level measurement into a flow rate, using an eleven breakpoint head-versus-flow characteristic curve. This chart is usually available from the manufacturer of the v-notch weir, Parshall flume, or other open channel device.

  • Page 93 Use the level breakpoints to enter head level values, and the volume breakpoints to enter flow volumes. Each segment defined by a head breakpoint requires a corresponding flow value, so that SITRANS Probe LU can make the head-to-flow calculations. Use the Flow table associated with your open channel device (Parshall flume, v-notch weir, or other measuring device) to calculate the flow rate for each breakpoint.
