Control technology increases safety

21 July 2008

Festo has unveiled a range of pneumatics safety technology designed to help automation systems manufacturers comply with Machinery Directive 2006/42/EC.
The KEC-S clamping unit, and the DNCKE-S cylinder clamping unit, provide a braking action, produced by a clamping unit acting on the piston rod under spring force, and can be sustained over long periods. The units suit applications involving varying loads and are unaffected by system leaks. Both products are certified by the BGIA.

Festo’s MS6-SV soft-start and exhaust valve will be available in the Summer, and serves as a unit for supplying machines and systems with compressed air. It is a self-testing mechatronic system with built-in safety redundancy, which complies with ISO 13849-1. A safety check of the piston rod position is performed directly by the valve during self-test, which simplifies wiring and installation.

The valve vents the system in critical safety areas in the event of an emergency stop. A safety feature is achieved thanks to the unit’s redundant twin-channel design – even in the event of a fault, safe exhaust of the system is ensured. Soft-start valves with sensor feedback integrated onto valve terminals are also now available, enabling entire system segments or critical function units to be pressurised slowly and safely.
