概述

Legal framework

Machine manufacturers and plant construction companies must ensurethat their machines or plants cannot cause danger due tomalfunctions in addition to the general risks of electric shock,heat or radiation.

In Europe, for example, compliance with the Machinery Directive2006/42/EC is legally stipulated by the EU framework directive foroccupational safety. In order to ensure compliance with thisdirective, it is recommended that the corresponding harmonizedEuropean standards are applied. This triggers the "assumption ofconformity" and gives manufacturers and operators the legalsecurity in terms of compliance with both national regulations andEU directives. The machine manufacturer uses the CE marking todocument compliance with all relevant directives and regulations inthe free movement of goods.

Safety-related standards

Functional safety is specified in various standards. For example,EN ISO 12100 specifies standards pertaining to machinesafety (risk assessment and risk reduction). IEC 61508specifies basic requirements for electronic and programmablesafety-related systems. EN 62061 (only applicable forelectrical and electronic control systems) andEN ISO 13849-1 define the functional and safety-relatedrequirements of safety-oriented control systems.

The above-mentioned standards define different safety requirementsthat the machine has to satisfy in accordance with the risk,frequency of a dangerous situation, probability of occurrence andthe opportunities for recognizing impending danger.

• EN ISO 13849-1: Performance Level PLa ... e; Category B, 1 ... 4

• EN 62061: Safety Integrity Level SIL 1 ... 3

Trend toward integrated safety systems北京西门子模块代理商通讯电缆总供应商

The trend toward greater complexity and higher modularity ofmachines has seen a shift in safety functions away from theclassical central safety functions (for example, shutdown of thecomplete machine using a main disconnecting means) and into themachine control system and the drives. This is often accompanied bya significant increase in productivity because the setup times areshortened. Depending on the type of machine, it may even bepossible to continue manufacturing other parts while the setup isin progress.

Safety Integrated Functions act much faster than those of aconventional design. The safety of a machine is increased furtherwith Safety Integrated. Furthermore, thanks to the faster method ofoperation, safety measures controlled by integrated safety systemsare perceived as less of a hindrance by the machine operator,therefore significantly reducing the motivation to consciouslybypass safety functions.
