Training objectives
- The main objective of the course is to provide the theoretical and practical basis for the verification of conformity of machinery with the essential requirements of the Machinery Directive.
The main knowledge gained will be:
hazards identification;
estimation and risk analysis;
reading, understanding and conformity validation of a safety circuit of a machine;
conformity validation of security solutions adopted by the manufacturer;
The main skills (the ability to apply knowledge acquired) will be:
drafting of the final report of compliance;
construction of the Technical File with justification of the solutions adopted and the residual risks, with their documentation on the User Manual and its reporting on the machine;
drafting of the Declaration of Conformity Prerequisites
- Understand the fundamentals of electrical and magnetic base.
Course programme
- The course includes 60 hours of teaching between lessons and visits to companies.
