We regularly prepare articles for technical magazines that deal with the safety of machines and plants, be this in general or with respect to special aspects or product families of machine safety. You can download the appropriate PDF file to your computer via the download function.
From hardware into the software The safety-related functions are increasingly shifted from the hardware to the software level. This is enabled by safety controllers, which can be flexibly adapted to the individual application. An example of such safety controller is the new PROTECT PSC System from the Schmersal Group. With its modular structure, this system is suitable both for relatively simple applications and complex tasks. If this controller is combined with the PDMS drive monitoring system, realizing new operating modes such as "set-up mode" and "process observation" become a piece of cake, as shows the example of a crane manufacturer, who has modernised his old boring machine with the latest safety technology. more
Safety sensors are often used as an alternative to the “conventional” electro-mechanical safety switches for the non-contact monitoring of the position of the safety guards installed on machinery and plants. An innovative sensor technology enables realising additional functions as well as a simplified integration of the safety switchgear both in the surrounding construction and in the safety circuit. more
In 2005, the BGIA (today IFA) conducted a representative survey, which revealed that the safety equipment on more than one third of machinery and plants is permanently or temporarily tampered. Although the necessary conclusions have been drawn from this survey, it can be assumed that tampering still exists today. This article demonstrates that tampering however can be prevented. more
In machine safety, the “after-travel” element is a critical parameter. The Schmersal Group offers a reproducible after-travel measurement by way of service. The following practical example explains the details of the measurement. more
