Safety technology

Safety technolgy in automation

According to a European Union ruling, the transition period for the new Machinery Directive ends on December 29, 2009. Both machine builders and operators must meet the safety requirements contained in the EN ISO 13849 standard from this date on, if not before.

Although the presumption of conformity of the not yet validated EN 954-1 was extended until the 31th of December 2011, just before the new Machinery Directive comes into effect, you are well advised to adhere already to the instructions of EN ISO 13849 and to equip your machines with sustainable safety engineering.

Safety - an issue we take seriously

EN 13849-1 builds on the qualitative aspect of EN 954-1 by including aquantitative calculation of safety functions. For many systems, this willmean that a safety control will need to be used.

As a member of the PLCopen Safety organization, Baumüller has addressed the new automation sector requirements, enabling it to offer you safety solutions in conformance with PLCopen Safety and which can be integrated into the machine’s automation system as a whole.

The scalable integration of the safety functions into the standard automation technology occurs with the consistent utilization of the resources already available within. The concept encompasses centralized, modular decentralized, and hybrid automation structures and is reflected in every area of the application.

In this way, Baumüller integrates its safety concept into all automation components – including communication – as well as into the ProMaster Engineering Framework.

S = Severity of the injury

S1 - Minor, reversible injuries

S2 - Serious, irreversible injuries, including fatal ones

F = Frequency/duration of exposure to the hazard

F1 - Rare or brief exposure

F2 - Frequent or continous exposure to the hazard

P = Possibility of preventing the hazard or limiting its effects
P1 - Possible under certains conditions

P2 - Hardly possible at all
