Outdoor-safe laser scanner

The OS2000 is a certified-safe laser scanner system for outdoor use. It combines the hardware and software of the Sick LMS outdoor laser measurement system with the safety level of the UE4470 safe programmable logic controller, which is certified as a safety component within the sense of the Machine Directive. Typical application examples of the system solution, which received approval from TÜV Rhineland, include door and gate protection, cranes, manned and unmanned vehicles, waterway structures such as bascule bridges or locks, and rail or conveyor systems.

In the OS2000 system, the monitoring and test signals of up to three LMS units are evaluated by the UE4470 safety network controller. The controller, certified as Safety Category 4 (EN 954-1) and SIL 3 (IEC 61508), handles the machine-side connection, evaluation of the output signals of up to three LMS units, control of the LMS units, evaluation of their output signals and control of the cyclical testing of the sensors on the basis of fixed test targets. The OS2000 safe laser scanner system thus fulfils the demands of Performance Level ‘d’ according to EN ISO 13849-1 and SIL2 in compliance with EN IEC 62061.

Depending on the task, IP67-protected laser scanners with scanning angles of 100° or 180° are available and can be used in environmental temperatures between -30 and +50 °C. The protective fields can be parameterised and evaluated as desired within the safety-oriented range of 20 m.
