Lets make this clear Darren60 .... you asked a question and we helped you best we can we supplied a wiring plan for a standard start/stop contactor, regardless of the numbers on your contactor the wiring plan we supplied should give you your answers, cursing whether written or suggestive is not allowed and will see you taking the high road to a ban if you persist, the control system of a machine is out of the scope of the 17th and to be working on it without relevant qualifications will only open a big deep hole for yourself... the question you asked is as almost as basic as they come when discussing control circuits and asking such a question shows us straight away your getting involved in work you dont hold the relevant qualifications or competence to ensure what you do is safe to use.
We make a judgement call on whether to help you or advice your out of your depth, in the case of your contactor swap we have made it clear how to wire up a contactor as well as also mentioning the responsibilities that come with working on control systems...
The correct way about this would have been for you to explain to the customer that you are not an Electrical Engineer and the work falls outside of the reg' you were taught under.... yes simple as it is you ae hopefully replacing like for like but you need to understand the machine and control system to know you are not replacing a part on a dangerous set-up.... also knowledge of why the existing contactor has failed and whether the original one was specified correctly for the job in hand.
Working parrot fashion by just swapping like for like can be a risky game in machine control so as constructive advice i would suggest you keep well away until you get yourself educated..... and trust me if you ever do you will begin to appreciate the advice and warning we are putting across on this thread .....
