Failsafe P070 to P072, P062 Offset Reading

P062 Offset Reading

Adds the specified value to the level reading, usually to reference the reading to sea level or another datum level.

Values	Range: -999 to 9999

	Preset: 0.000

Parameters

Failsafe (P070 to P072)

As preset, in the event of a measurement or technical difficulty, the SITRANS LU01 holds the Reading, Bar Graph, mA outputs, and relays at their last known values.

To operate process control equipment under these conditions, alter the following parameters as required.

P070 Failsafe Timer

The time for invalid measurements to elapse before Failsafe State activates.

Values	Range: 0.0 to 9999

	Preset 10.00 minutes
	Preset 10.00 minutes
Altered by	•	P003 Maximum Process Speed
Related	•	P129 Relay Failsafe

In the RUN mode, when a difficulty first occurs, the Reading, Bar Graph, relay status, and mA outputs are held at last known values and the Failsafe Timer is activated.

When a valid measurement is made before the timer expires, the SITRANS LU01 advances to the new material level (if changed) as normal (per Measurement Response, P003) and the timer resets.

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.
