Bezpečnostní funkce u regulovaných pohonů

Abstract

The work will focus on familiarization with the concept of machine safety functions, norms and history capabilities meet safety standards for industrial machinery. As an objective of the work is introduction with various options to implement security circuits compare their advantages and disadvantages for the installation, operation and maintenance. The theoretical part describes the standard requirements for safety systems and their parameters practically test the tools Siemens Safety Evaluation Tool, using components from Siemens and firms PILZ. In the practical part, thus adding to the program as well as third-party circuits. I chose the commonly used safety relays, which are used in practice in many applications. All components describe in detail the practical part. Including an illustrative view. The aim is to compare different solutions and to design a system for testing the safe shutdown
