Designing Safety-Related Machinery Control Systems in Accordance with ISO 13849 and IEC 62061


This three-day technical training course will cover Functional Safety Standards and concepts related to the EU Machinery Directive.  Standards covered in this course include ISO 13849 (Safety of Machinery – Safety-Related Parts of Control Systems) and IEC 62061 (Safety of Machinery – Functional Safety of Safety-Related Electrical, Electronic, and Programmable Electronic Control Systems).  In addition, other topics such as Hazard Identification and Risk Assessment in accordance with ISO 12100 will be covered.  Case studies such as motor drives and safety PLCs will be used to provide examples of how the requirements and concepts of the standards are applied.
