Excerpt from the document:
This document has been developed for machine designers within manufacturing plants and also to assist system integrators and OEM‘s.
The specification covers the implementation from input devices through to final power elements giving examples utilizing a safety relay based solution and a configurable controller solution.
The diagrams in this document should be used in conjunction with the additional recommendations detailed in:
- EN 60204 – 1: Safety of Machinery – Electrical Equipment of Machines
- ANSI B155.1 – Safety requirements for packaging machinery (North America ).
- EN 415 – 4: Safety of packaging machines – Palletizers and Depalletizers (Europe).
Note: Different regions may have different guidelines.
When implemented correctly the circuits described in this whitepaper will comply with the requirements for PLe (Performance Level) to (EN) ISO 13849- 1: 2015 and SIL3 (Safety Integrity Level) to IEC 62061: 2005.
A detailed description of those standards is provided in Safebook 4, available from Rockwell Automation.
For muting Rockwell Automation provides detailed description of the complete safety function:
