We offer a selection of technical articles dealing with the safety of machines and plants - both in general and on particular aspects of product families for machine safety. Some of the contributions are from Schmersal employees, others are written by independent specialists, e.g. from industrial assessment organisations. The applicable PDF file can be stored on your computer by means of the download function.
Ergonomics on meat-processing machinery The control units of the machinery from Seydelmann are designed from scratch according to the principles of hygiene-compliant design and offer a highly ergonomic operation as well. In this way, the man-machine interface also meets the highest requirements. more
What is a Performance Level (PL)? Expressed in simple terms, a PL concerns the safety-oriented overall quality of an SRP/CS architecture (= deterministic perspective) and the SRP/CS reliability (= probabilistic perspective). more
When observing the entire mechanical and plant engineering field, two hand switches surely belong to the more rare, but more costeffective safety devices. However, they are not widely used in metal-working, especially in press technology. The Pressen- und Maschinenbau Erfurt GmbH – short: PME – relies on two-hand control panels by Elan for their metal forming presses. more
The "category principle" for Safety-Related Parts of Control Systems (SRP/CS) of machinery belongs in the past: The familiar control unit categories of EN 954-1:1996 have been replaced by performance levels of EN ISO 13849-1:2005 and must be applied by the end of 2009. What now changes for the designers and safety engineers? more
