The target: Monitoring devices conforming to the standards
The standards and regulations for machine safety form an important basis for the selection of safety switchgear. We are happy to provide you with assistance in this respect. We work in close co-operation with the standardisation authorities and can actively support you in the task of designing monitoring devices to particular national and international standards in each case. |

Initial information on this complex subject is to be found here on our homepage. The new edition of our book “Safety on machines and engineering plants” contains appreciably more information on the harmonised safety standards in the EU. And for concrete questions, our specialist engineers for safety technology are at your disposal. |
We are pleased to note the continued significant interest in this brochure, which is now issued in its 3rd edition. A contributory factor may well be that until the end of the year (up to 31.12.2011) the harmonised standard EN 954-1:1996 can be used as basis for the implementation of safety-related parts of control systems (and that this was not withdrawn with loss of the so-called presumption of conformity on 29.12.2009 as originally planned). more
Simplification of the risk analysis to DIN EN ISO 13849-1
In order to further facilitate this task for the engineers and to provide for a clear and praxis-oriented valuation base for the safety of machine controls, the Schmersal Group has created a library for its products, which can be directly imported into SISTEMA. more
Projects and libraries in the new version are compatible with those in Versions 1.1.x. more
Before the machine designer can begin the calculation of the Performance Level, he must deduce from his circuit diagram the safety-related block diagram illustrating the implementation of the safety function in functional channels and tested components. The SISTEMA-Kochbuch 1 deals with this unusual and difficult step of abstraction and with the subsequent step, the transfer of the blocks and their characteristics into SISTEMA. more
2006/42/EC was finally adopted on 25th April 2006, and was published in the Official Journal of the EU (L157) in June. more
Arrangement of the EN standards. The requirements of the Machinery Directive are substantiated by means of the EN standards, which are divided into three hierarchically arranged type classifications..... more
How safe must machines be? To the basic thoughts which follow through the whole standards work is the procedure for the design of a safe machine layed down in Appendix 1 of the Machinery Directive and detailed in EN 292. more
