30 July 2007

Many managers, specifiers and design engineers with responsibility for machinery safety-related control systems are concerned about EN ISO 13849-1 superseding EN 954-1, Safety of machinery. Safety related parts of control systems. General principles for design. For example, there is some confusion over the new Performance Levels and whether they are the same as the familiar Safety Categories of EN 954-1. And then there is the question of the calculations that need to be performed to validate the design for the safety-related control system. [See this more recent announcement confirming the extended transition period for EN 954-1 - Ed]

Pilz says it probably knows as much as anyone about the new standard (the company had representation on the committee that developed ISO 13849-1), so Pilz is organising a series of six seminars to demystify the migration from the old standard to the new one. The seminars will explain the current legal status of the two standards, the timescale for the changeover, the differences between the standards, and when each should be used in preference to the other.

Delegates will be shown how to use the new standard and how to perform the necessary calculations to validate the design for the safety-related control system - which may be electrical or non-electrical.

Six seminars are being organised around the UK, and the number of places is strictly limited. The dates and venues are as follows:

  • 11 September - Horsley Park, near Leatherhead
  • 18 September - Museum of Science and Industry, Manchester
  • 2 October - National Space Centre, Leicester
  • 31 October - Tewkesbury Park Hotel, Tewkesbury
  • 7 November - Northampton Saints rugby ground, Northampton
  • 21 November - Darlington Arena, Darlington

Each delegate will receive documentation, a free copy of the Pilz PAScal safety calculator, light refreshments and a buffet lunch.
