Helps with a start button mate
What's the blue wire for !!!!

Just noticed it on the photo
oops

Monkee,

I'm assuming the start button is under the black 'shadowy' bit on the right?
If so it should be wired in parallel with aux contact 13 and 14.
Your coil/control cct is wired 440v............L1-A1 and then L3 through O/L start/stop and aux to A2 of coil.

Phenomenal Tony. That's taking advice to another level.

I'm slowly going through all my drawings and animating them.

Another gem Tony absolutely brilliant.

Now if the sparks I served my apprenticeship under had animations like that it would have saved me a few sleepless nights trying to understand control circuits !

All they had was some tattered and torn ( covered in coal dust and oil) wiring diagrams that they produced from their inside pocket now and again ffs lol.

I'll take the 1st stab at fault finding and put my head on the block.

From the OP it sounds like your closing the contactor manually with a screwdriver.
This will indeed power the fan up and the coil will hold in due to the N/O auxilliary contact between 13 and 14.
Now if ,as you say, nothing happens when you push the start button then it would appear you haven't wired it correctly across 13 and 14 ( in parallel with aux contact).

The number of drawings I think you've got, that's you busy for the next 10 years!

hi bud the blue is emmitted to the fan not required the start button is o n the right remember the cover is taken off

 

[monkee]

hi guys thanks for the amazing response the switch part is not clear but it is wired in just hard to seee in the picture it is the small black bit on the right

it was given to me in this state along with the fan i just had to add the power but i did remeber that the coil needed a netrual so i removed the over load and connected in i have not touched any wires around the unit

i should just check that the switch is making or should renew it all is this an old unit thanks again guys lost of cars to spray ha ha

Listen mate.........your messing on with something lethal and telling me the coil needed a Neutral does not tally up with the photo you posted.
If the coil is 230v then fine you need a neutral.
Your photo show the coil/control circuit is wired to 430/440 volt across L1 and L3 !
Did you know that or are you just guessing at all this?

Get a spark in before you blow that coil up or the sad mechanic who turns it on

You've removed the overload? Why?
Put it back!

The unit will be wired as shown in the animation. As Allan said it doesn't require a neutral.

Allan that was OTT even by my grumpy standards.

Excellent work with the animation Tony. If one critique (ducks!!): The third image changes back to the first image before I can read all of the text on the left in one go. But I am a slow reader!

It's also done to the American standard which is OK for 400V control but wrong for UK grounded control.

Have sent you a PM.
