Safe radar system - LBK System


Sicheres Radarsystem - LBK System

Safe protection zone monitoring in rugged conditions

With the world’s first safe complete solution for protection zone monitoring based on radar technology, Pilz is expanding its portfolio in the field of safe sensor technology. It consists of the safe radar system LBK System from Inxpect S.p.A. and the configurable small controller PNOZmulti 2. This complete solution enables complex applications and rugged environments to be monitored safely, even outdoors. The robust radar technology ensures high availability even where there are external influences such as dust, dirt, rain, light, sparks or shock.

Safe protection zone monitoring with radar technology

With the underlying radar technology (FMCW: frequency modulated continuous wave), the LBK System offers volume monitoring with a frequency of 24 - 24.25 GHz and it can be used up to SIL 2, PL d and Category 2. The safety-related functions covered by the system include the “detection function” and the “restart interlock”. While the detection function brings the machine to a safe state as soon as the danger zone is violated, the restart interlock prevents the machine starting up automatically when there are still persons in the danger zone.

Flexible setup of protection zones

The safe radar system solution includes, depending on the application, up to six radar sensors, one control unit and the configurable safe controller PNOZmulti 2. Depending on the size of the area to be monitored, a wide or narrow protection zone can be set up for each sensor: the wide protection zone has an opening angle of 110° horizontally and 30° vertically, the narrow protection zone has an opening angle of 50° horizontally and 15° vertically.

Simple configuration with the LBK System Configurator

The actual protection zone of the sensor depends on the positioning, installation height and inclination (horizontal/vertical) of the sensor. This way, flexible shapes can be created for the protected areas. As a maximum, an area of 15 x 4 m can be monitored. The sensors are selected and configured via the appropriate Configurator. In addition to the protection zone, it is also possible to configure a warning zone. If a person violates the warning zone, this may be signalled by an optical signal, for example. This way, productivity of the plant can always be maintained. 

Benefits of the safe LBK System

  • Complete solution for safe protection zone monitoring in complex applications or with external influences in combination with PNOZmulti 2

  • Insensitive to dust, rain, light, dirt, steam and shock

  • Series connection of up to 6 sensors

  • The Configurator is used to select the sensors and set up the protection zone

  • Warning zone to signalise approaching objects

  • Integral muting for the whole system or for individual sensors

  • Restart interlock to prevent the machine restarting when there are people in the danger zone

Pilz PSENopt II
The second generation of light curtains, PSENopt II, provide safe access to the production process and provide finger, hand and body protection, depending on the requirement. The first Type 3 safety light curtains are specifically designed for applications up to PL d of EN/IEC 61496-1. Type 4 light curtains are also available for applications up to PL e in accordance with EN/IEC 61496-1/-2.

Phoenix Contact Axioline
The modular station communicates with a PROFINET controller, e.g., a distributed control system DCS, via a bus coupler. As an option, up to eight PROFIBUS PA segments can be connected to the individual proxy outlets in a compact way. To ensure the individual segments are immune to interference, appropriate shield connection technology is available.

Schneider XIOT
The Internet of Things \(IoT\) is the extension of the Internet to connected devices. Telemecanique Sensors offers a wireless solution to collect data from remote equipment and use this data, via the Internet, on a PC or mobile device. The XIOT Cloud connected switch from Telemecanique Sensors is based on LPWAN \(low power wide area network\) technology, operated by Sigfox. The Sigfox network covers 32 countries and is already very extensive in Europe. It is also being rapidly deployed in the US and Asia-Pacific. It uses antennas with a range of around 50 km. The map on the Sigfox website shows exactly which areas are covered by the Network.
