There are 2 EU directives you need to know here -
- 1 The Machinery Directive
- 2 The Use of Work Equipment by Workers at Work Directive
These directives are directly related to the Essential Health and Safety Requirements (EHSR's) from the machinery directive and can be used to conform the safety of equipment in the Use of Work Equipment Directive.
Reading your responses to the issues we raised its becoming clear you really have no clue as to your requirements and probably don't realise how to do a risk assessment and design, alter or extend a system to conform to it.
The OP set-up is a manual start and no mention to it ever been supplied as an auto option, of cause some feeders may be sold with this option but to be CE compliant it would have to comply with the above - if any one alters, makes additions or designs the control system of any machinery then they must do so having a full knowledge of the above as well as the LV Directive of which the BS 60204 will probably play a big role...
Mock it and drop silly comments all you want but all this does is show your incompetence in this field, its not just about understanding how to achieve the desired control system, to be fully competent you need to know the weight of responsibilty you place on your shoulders. By doing any additions or alterations to any machinery exempts the manufacturers of liability and places it on you shoulders - any future accident that comes to the attention of H&S will see you answering some very tough questions, I've been there a few times and shown I took all the necessary steps to conform to regulations and met the required risk cat' placed on the machine....(It was the operators by-passing safety measures that was the issue on both cases), like I said before; this may be a simple case of the machines design allows for auto set-up with minor alterations and still meets its safety cat' but it must be mentioned and made clear that it may breach the required directives by making alterations without ensuring the machinery still complies.
t-s a pig feeder is a machine it has no bearing if its in a factory or a field it still has to meet all the EU regulations and directives, these strict measures are put in place because people get killed and seriously injured daily and mainly through mis-use, over-riding safety systems and lack of understanding to the dangers, we have to build machinery and controls to be idiot proof because these are the people that tend to run them on minimum wage.
I had a similar set-up where they had been quoted £120 to have an auto feature with a timer, I quoted over £700 and explained why to the company director, he went with my quote and informed the other guy he lost the job because he didn't do a risk assessment and bring it into line to comply with an auto start option...
