Is it a machine or a system?

Paul Roman
Good afternoon


I am looking for someone who can help advise regarding an installation of materials handling equipment.  Within the installation you have numerous conveyors, automated cranes, robots cells as an example. Each having a control panel which would isolate that individual item.  The question I have is when you take each of these 'machines' so various conveyors and automated cranes aand they are interconnected can you still treat them as individual machines, thus the electrical design falls under the machinery directive, or do you treat it as a distributed systen and therefore it would be classed as a system and perhaps therefore meet different criteria for electrical design.


I am trying to ensure that our designs which are designed within mainland Europe under the machinery directive meet the requirments as an installation in the UK, where some are looking at it as a distibuted system and therefore applying 17th addition for example.


Any help greatly appreciated.


Paul.

    Hi Roger


    Thanks for the response.


    We have had numerous debates interanlly but my view is very much (reading what the Machinery Directive is defined as) that it is numerous 'machines' making up a whole and therefore  the machinery directive is the starting point, which then cascades down to the Low voltage standards for example.

    The confusion has arisen as the 'machine' which is a number of conveyor systems connected is designed under a standard produced within our group in mainland europe, but people within the UK offices are questioning if the design meets the requirements of the UK. Whereby some believe it shoudl be designed as a distributed system not a maachine.
