Help Needed for Son

Hi everybody!
I'm wondering if anybody can help me with this diagram, my son has been handed it for college and has no idea (i'm a fitter so i'm useless!)

He's been told to add things to this diagram, can anybody show him/me how it is done...

thanks!

Yip it is a bread and butter circuit for industrial sparks, but we like to see an effort by the student rather than giving the answers straight out.

So I will give a big hint for the first two or three parts that have been asked for.

Starts go in parallel and stops/trips go in series. If he looks at the circuit he will see a couple of stop/trips wired in already and the start and hold on contact wired in.

If you are in the central Scotland area I don’t mind taking him through it.

Get him to have a shot and get back to us.

Also get him to say what he is not sure about, so that we can enlighten him.
