Troubleshooting

If the preceding remedies have not produced satisfactory results, the false echo has to be ignored. Extend Near Blanking (P800) to a distance (from the transducer face) to just beyond the distance represented by the Reading. This also increases the nearest distance the material level/object may come within the transducer face and still be detected.

If increasing Near Blanking is unacceptable (the transducer cannot be mounted higher) see Auxiliary Transducer (P725). Otherwise, the TVT Curve must be raised in the area of the false echo.

Connect an oscilloscope to the SITRANS LU01, ( see Enhancement Parameters Scope Displays, P810). Adjust the TVT Start Min (P833), TVT Start Duration (P834), and TVT Slope Min (P835) slightly.

Continue making minor TVT Curve adjustments and taking new measurements while observing the Echo Marker position until the Echo Lock Window repeatedly locks onto the true echo. Verify the false echo is still ignored, regardless of the vessel material level, or empty/fill activity.

Wrong Reading

If the Reading is erratic, or jumps to some incorrect value periodically, ensure the:

1.Material (object) surface monitored, is not beyond the transducers maximum range.

2.Material is not falling in the transducer sound beam.

3.Material (P002) value matches the material monitored.

4.Measurement Response (P003) is not set too fast.

5.Transducer (P004) type entered matches the transducer used.

If the periodic incorrect value is always the same, see Fixed Reading. If the incorrect value seems to be random, verify the material surface to transducer distance is less than the Empty value entered plus 20%. If the material/object monitored is outside this distance, increase Range Extension (P801) as required.

If the material monitored is a liquid, check for splashing in the vessel. Decrease Measurement Response (P003) as required to stabilize the Reading, or install a stilling well (contact Milltronics or your local distributor).

Access the Noise (P807) parameter. If the peak value jumps wildly, verify the transducer cable shields are connected to the SITRANS LU01 shield terminals and not to ground elsewhere.

If the SITRANS LU01 is mounted in close proximity to (or transducer cables run near those of) another ultrasonic level monitor, see Level System Sync (P726).

Temporarily disable nearby SCR control drives, high voltage or current contactors. If the condition disappears, move the SITRANS LU01 to another location.

Set Echo Lock (P711) to "max verification" (response to material level changes may be slowed somewhat).

LU01 specifications

The Siemens LU01 is a state-of-the-art train control and signaling system designed to enhance the safety and efficiency of rail networks. This sophisticated system leverages advanced technologies and innovative features to ensure seamless train operations, lower maintenance costs, and improved overall performance.

One of the main features of the Siemens LU01 is its implementation of the European Train Control System (ETCS). ETCS is a vital component in modernizing rail infrastructure across Europe, aiming to standardize various train control systems for enhanced interoperability among different national networks. The LU01 facilitates the integration of ETCS Level 1 and Level 2, allowing for both trackside equipment and onboard systems to work in harmony to manage train movements effectively.

Additionally, the LU01 employs a decentralized architecture that enhances system reliability and minimizes downtime. This design means that it can operate even in the case of individual component failures, ensuring that train operations remain uninterrupted. Furthermore, the LU01 utilizes advanced diagnostic tools and predictive maintenance technologies to monitor system performance continuously. This proactive approach allows for early identification of potential issues and timely maintenance, which contributes to reducing operational costs.

Another critical characteristic of the Siemens LU01 is its capability for real-time data transmission. The system integrates wireless communication technologies, enabling constant connectivity between trains and control centers. This feature allows for real-time updates on train positions, speeds, and other critical operational data, thereby enhancing situational awareness for train operators and maintaining optimal schedules.

Moreover, the LU01 is designed to be compatible with existing rail infrastructure, ensuring a smooth transition for railway operators looking to upgrade their signaling systems without extensive overhauls. This adaptability makes it an appealing choice for both new projects and retrofitting existing rail networks.

In summary, the Siemens LU01 stands out for its cutting-edge features, including support for ETCS, decentralized architecture, real-time data communication, and compatibility with legacy systems. With these technologies and characteristics, the LU01 significantly contributes to the safety, efficiency, and sustainability of modern rail transport systems, making it a pivotal solution in the evolution of railway operations.
