If things go wrong on an install it's no good saying to a paying customer "well that's what I was told on a forum" does your customer know you're getting most of your information on here? even how to make a good job of traywork lol

don't know why that posted twice
 
It's not for a customer, it's an install at the company i work for. Im the plant manager here, but do all the maintenance, electrical and plumbing work. Well i do everything really.

Yes the tray work isn't brilliant, im totally over that, it's not affecting the operation of the circuit, ill get it looking nicer next time, and no i fully understand it's not ideal getting tips from a forum, but i'm not entirely sure what else i should do. For topics i am unsure about, i seek help where available, and, for all intents and purposes, i have now installed a safe and operational circuit after some guidance. I'm happy.
 
sorry Wade I was getting misled by your link to a website I thought you were an electrical contracting company, my mistake, my advice would be if they've employed you as a plant manager why don't you contract the electrical work out to a qualified electrician? and then manage the contractors?
 
That (was) my company, don't work self employed anymore, but as the websites suggests i only did domestic jobs and event power, now i have moved into a more industrial environment by proxy i guess.

Yes some work is contracted out, so typically as a plant manager i would be managing the tasks to be completed by outside contractors, but because im fairly handy, i started to do everything my self, and then i ended up falling into the control side of things, of which i know very little. Everything else i am totally happy with, but since having been involved in PLC's and the actually operation of heavy machinery and their panels, i have for sure lost my way a little.

I am however, picking it up quite fast, and rest assured, and i am being more sincere, any jobs i seriously don't feel comfortable with, i simply get people in, that goes for everything else i do outside of electrics. But, electrics kill people, a badly soldered yorkshire joint on a soak away will just get someone wet, so i fully respect the difference and always have.

I think people here think i just dive head first into serious work with no idea what im doing...... *cough* ........ but i do honestly do as much research and reading and general background as i possibly can before i even get the tools out.

I do need to remove that link now you mention it.... not that its even done me any good lol! But i am just a humble plant manager now.
 
All I can say Ben, it must be a laid back plant to manage. Been there got the tee shirt and made the maintenance guys life a misery. I hadn't got time to go delving in to things. I'd got 50 guys to keep employed in some way or another. Fix that bloody plant NOW! or I'd have you shot at dawn!
 
Hmmm... i applaud your enthusiam wade but even with the advice give and links the risk assessment and safety side of a control system isn't something you can work out, learn or be competent to do in a short space of time, there are so many indepth requirements as well as positioning segregation and design of the control system that couldn't have possibly even been touched on here in such a short thread up to press.

Ive briskly wisked through the posts and il stand corrected but i see no mention of seperate reset in that resetting of the E-stop will not on it own re-energise the disabled circuit or control circuit as a seperate manual reset will be required to be operated to be able to start the the dropped out circuits.

I can recommend you pop into your local Engineering wholesalers and pick up the free booklets from the likes of Pilz, Schneider or rockwell....i have the rockwell catalogue on their control safety products and is a wealth of info although biased with their products as solutions it gives an indepth read-up on how to risk assess to find what safety catagory the machine falls under , relevant EN an IEC standards, examples of safety set-ups with wiring diagrams for each catagory and all the formulas for designing more advanced systems where distance to hazards need calculating in relation to safety detection circuits.

I know you won't take offense when i say you really shouldn't be entertaining designing your own E-stop systems with the help of a forum as too many questions and answers to ask and know about the machine and job and user interaction that could be possibly asked .

Tred carefully as no PL-insurance will cover you for this unless you have specified it within your duties to design and alter or build control systems, if you or your company has this clause covered in insurance you will probably still lose cover if it dosn't comply to EU Directives and regulations. If the worst case happened without such cover it could bring your company down.
 
Ok, aside from Tony's useful input and don't feel you need to come back with anymore helpful nuggets of wisdom here old boy im sure you have plenty of other people to go and wittle away at.

Aside from college, as i just can't go down that road for an array of reasons anymore, where and how is the best way to read up on the "regs" of such topics such as control circuits, industrial control and the like. Are there courses available that are recognised, and what is the best way to learn more. I have a lot of reading to do which some kind forum members have sent my way, and i am attending a NEBOSH course in a month as i will be taking over the SHE managers job role in the forthcoming weeks also.

Yes it is a small company, and yes for the last ten years it has been a self sufficient entity with no outside involvement in regards to maintenance and everything else. Repairs and new builds of gear have taken place in a very Heath Robinson manner but i was asked to come in and take over that aspect of things as well as over see the design and build of any new engineering projects we are undertaking.

I undoubtedly don't hold the experience many of you do, and undoubtedly have not "commanded" as many men as some of you either, led the charge through the breach at the Tea room 2 minutes before break time, or even shouted at a poor maintenance tech till he cried and curled up in the fetal position, but i have just started this career no more than two years ago, and have not had my hand held through the beginning of it so have done my very best to work things out for myself and do what i feel is best. I do my upmost to keep safety as a priority and yes, as pointed out, sometimes get it wrong or have done things in somewhat of an unorthodox fashion, so i come here to get a little steering in the right direction, not to highlight my incompetence for the pleasure of the vultures here who love to take people apart for a good ego massage.

This forum has fast become more of an executioners social club, where people wait for "silly" questions just to run in swords drawn and hack the poor bugger to pieces. But in my opinion, better a stupid question asked and a person leaves understanding, then no question asked at all. So i fully intend to just keep on asking.

For those of you who deem me to not be worth the effort, thanks for coming this far but by all means do one. But for everyone else who has personally gone out of their way to help me, i appreciate it very much.
