Example calculation of the PL for an electromechanical safety switch as door position sensor What is SISTEMA? SISTEMA provides developers and testers of safety related machine controls support in the evaluation of safety in the context to EN ISO 13849-l.The tool enables to model the structure of safety-related control components based upon the designated architectures, thereby permitting automated calculation of the reliability values. The SISTEMA program may be downloaded and distributed to third parties free of charge. The software was published by IFA www.dguv.de/ifa. A library with...

Fault exclusion on an electromechanic safety switch with and without guard locking Consider the following when working with fault exclusions: The fault exclusion should remain restricted to the mechanical parts of a switch. The electrical connection should comply with the required category (compare EN ISO 13849-1:2015, section 7.3: „lf faults are excluded, a detailed justification shall be given in the technical documentation." and EN ISO 13849-1:2015, section 8: „The design of the SRP/CS shall be validated ... . The validation shall demonstrate that the combination of SRP/CS providing each...

Step-by-step procedure for the determination of the system performance of a SRP/CS Risk diagram 1. Determination of the required PL (PLr) acc. to EN ISO 13849-1, Annex A Determine the risk (use risk graph or, if applicable, C-Standard) Work out a (constructive) solution Document the remaining risks point them out in the user information 2. Determination of structure (category) A structure must be found, with which the determined risk can be minimized 3. Determination of MTTFd values for electromechanical safety components Use B10d values for calculation of MTTFd. The value for every safety...
