    not written out im afraid just did phase 6 at christmas tho so it would still be fairly fresh. dont u have any notes on it?


  • Registered Users Posts: 420 ✭✭NoseyMike2010


    I have no notes ..... I have a degree in Engineering but am seriously thinking of becoming an electrician. I am trying to gather some of the notes/ exams and having a look through them over the summer .... since I have loads of time!!!!!! Any help would be awesome.


  • Registered Users Posts: 630 ✭✭✭mazthespark


    well the whitfield books would be a good start to give u an idea majority of course is based on them neway. and you can buy them most places


  • Registered Users Posts: 420 ✭✭NoseyMike2010


    I'll start looking into that .... Do you still have a copy of your notes? Is it difficult to get copies of the differerent Phase material??


  • Registered Users Posts: 630 ✭✭✭mazthespark


    i do ya but generally there given out by lecturers to students so a lot of it is hand written etc.

    Any chance of getting it scanned? Please.


  • Registered Users Posts: 630 ✭✭✭mazthespark


    theres 4 lever arch folders and thats only half of it ha! where abouts are u in the country?


  • Registered Users Posts: 420 ✭✭NoseyMike2010


    Yikkeeeeeeees Thats alot. If you had a big office printer it you could feed it into it! If not guess it would take ages.

    I'm based around the Kerry area. Is there much information about PLC, Control and automation systems?


  • Registered Users Posts: 630 ✭✭✭mazthespark


    ah rite based in galway myself. theres very little really the course is very outdated in my view. if thats the side ur interested in dit run courses in that side of thing and some colleges do a automation type course also think sligo it do one called mechatronics.


  • Registered Users Posts: 420 ✭✭NoseyMike2010


    Don't think i could face going back to Uni again .... mainly because I have no money. Was going to try learn it myself and see where it takes me!!

  • Registered Users Posts: 630 ✭✭✭mazthespark


    well some of them are distance learning so u work in ur own time and just attend the odd lecture or practical. was looking into them myself im recently qualified but have a huge interest in that area of it


  • Registered Users Posts: 420 ✭✭NoseyMike2010


    Can I ask .... Are you a qualified Electrician or have you been to Uni? If I were to do the electrician apprenticeship how long would it take ( i have a degree!)


  • Registered Users Posts: 630 ✭✭✭mazthespark


    qualified spark. took 4 years. i dont think a uni degree helps you but i know being qualified allows you to skip first year in elec. engineering and similar courses


  • Registered Users Posts: 420 ✭✭NoseyMike2010


    4 years ... ummm. But at least I'd have work. I must look into it.

    Is any of your course material available online to download???

    Q 1:

    Truth table:

    S1 S2 S3 K1
    0 0 0 0
    0 0 1 0
    0 1 0 0
    0 1 1 0
    1 0 0 0
    1 0 1 0
    1 1 0 0
    1 1 1 1

    AND logic: In other words you only get an output if S1 AND S2 AND S3 are closed.



    Q 2:
    Pressure Transmitter
    Temperature Transmitter
    Switch

    Q 3:

    If a device was connected to the first input of a PLC the terminal would be marked "X0". When refering to this in the PLC code it would be identified as "X0" in the code. That way the PLC "knows" which input the programmer wants to refer to.

    The first output would be "Y0". The same applies as above.

    The PLC will scan all of the I/O to establish their status, solve the logic of the programme and the switch the outputs accordingly.

    u need work as an electrician for the four years too its done in phases. not really available online but check out fas.ie for details on apprenticeships.


  • Registered Users Posts: 420 ✭✭NoseyMike2010


    Thanks 2011 :D:D:D Keep up the good work.

    I will study your answers tomorrow when I am fresher!!!


  • Registered Users Posts: 420 ✭✭NoseyMike2010


    Mazethespark ..... I will look into this. If you do manage to find a scanner I would be grateful for a copy of some of the notes to get me up and running.

    NoseyMike2010 most sparks get qualified and then if they want to get more qualifications,they decide to go back and get a degree or do night courses in certain aera's ie plc's or testing etc etc,why are you thinking of going back to do a trade,what was your degree in electrial engineering or electronic engineering?surely there is area's of your course that you enjoyed more than others,would it not be better to be looking into developing your skills in these area's


  • Moderators, Home & Garden Moderators, Technology & Internet Moderators, Regional East Moderators Posts: 12,591 Mod ✭✭✭✭2011


    Glic83, what I am seeing is the opposite. For example Engineers that have a degree in mechanical engineering working in automation. This seems to happen quite a bit nowadays either because engineers find a particular area more interesting or because there is employment in one field and not in another. Within a some departments such as process there is quite a bit of overlap and cross training. That is what I am seeing anyway.

    I agree with above post it is unusual but not unheard of to get a degree and then do an apprenticeship.

    My advice would be to specialise in PLC's,Robotics,energy management or motor control as specialists in these areas (pre boom) were more sought after than say domestic electricians especially in process control.

    I admired electricians who could fault find and programme PLC's in fairness their role was nearer software engineer than electrician.

    Even now there are still a lot of factories/plants with fairly hi tech equipment that needs looking after.

    Pavb2,

    to be honest I misunderstood what noseymike was saying. I thought he was talking of changing from working in 1 type of engineering role to another. I agree 100% with your post.

    I think being a qualified electrician is great and will always stand to you. But if I was an engineer and that is not a qualified electrician I would not be interested in serving my time. Especially now when so many experienced electricians are out of work, what is the point? Serving your time is not easy, I should know!

    If you are going to go back to education I would suggest that you do a masters or study a different aspect of engineering in a area that there is employment in that interests you. That is my view anyway, each to their own I guess.


  • Registered Users Posts: 420 ✭✭NoseyMike2010


    Pav2b/2011,
    Its the hands on experience that I am lacking. Thats why i was thinking of training to become an electrician.

    I would like to get into PLC's and automation side of things. I was hoping to get a copy of the these from an electrician but no look so far. Can anyone answer the questions I have attached and send them to me.


  • Registered Users Posts: 1,519 ✭✭✭glic83


    to be honest the plc stuff is only in phase 6 and its only really a basic introduction into it,i would be looking doing a plc course in 1 of the I.T's and go from there


  • Registered Users Posts: 420 ✭✭NoseyMike2010


    Can I get a copy of Phase 6 off you guys. The PLC section is all I need. I really want to learn the logic side of things and work from there.


  • Moderators, Home & Garden Moderators, Technology & Internet Moderators, Regional East Moderators Posts: 12,591 Mod ✭✭✭✭2011


    I would agree with glic, the PLC stuff covered during an apprenticship is only really designed to give an appreciation of PLC, nothing more.


  • Registered Users Posts: 420 ✭✭NoseyMike2010


    Oh .. Ok. Thanks 2011. Do you recommend any books I can start off on. Remember your talking to a person with very little knowlegde of PLC's, Cabinet design, Ladder logic ... etc etc. I got a copy of the 2 attachments from another guy .... not sure if they are Uni tests or from some other course. i would like to be able to do these.


  • Registered Users Posts: 630 ✭✭✭mazthespark


    i also have an interest in the whole automation side and before i even went to Phase 6 i looked over a few things to get me going. found this site very useful.
    http://www.plcs.net/

    theres a tutorial on the basics on it

    the main thing we used do in fas was convert schematic diagrams into ladder diagrams all plc and automation was very basic indeed so if that was ur main reason for doin apprenticeship id pass. try get in with a instrumentation crowd maybe mite be best for practical automation experience


  • Registered Users Posts: 1,494 ✭✭✭m.j.w


    Hi, dont know if this is any help but you can get all the notes from phase 2 of the apprenticeship from here

    http://www.ecollege.ie/site/liu/html/Electricalnotes.html

    Ive just finsihed phase 2 in fas, obviously the lecturer will give you other notes to take down but these are the notes that they hand out to you. Everything is there. Hope this helps

    Q6=
    Branch 2 20ohms/200v = 10amps, Total Impedence=20ohms, phase angle = -90degrees


    Branch 1 Total impedence= square root of 16squared + 12squared =20ohms,
    20ohms/200v= 10amps, power factor = Resistor/Total Impedence= 16r/20ohms= 0.8, phase angle= cosign teta 0.8= +36.86degrees

    Drawing your diagram with above figures.

    Q7= #1 meter - The current coil is placed in series with phase R and the voltage terminal is connected to phase S
    #2 meter - The current coil is placed in series with phase T and again the voltage terminal is connect to phase S

    Wattmeter #1+#2 = Total power.


    If you need any help you dont be afraid to drop me an email,you have my address.

    Cheers
