DOL starter 7.5HP, 3 ph motor

Fully agree there should be some form of lock on the lid.

... this mixer is a heap of gypsy waste and needs to be cut into manageable pieces of scrap so it can be carefully loaded onto their flat beds when no one is looking at lunch time.

It's not worth my time, materials, or potential swearing to get functional. The shaft is totally off alignment, the gear box is on its last legs, the bearings are about as smooth as Brian Blessed's chin and the pneumatics leak more than a pensioners underpants.

Sooner is finds itself smelted down to make tea spoons the better.

So, all in all, your having a fab time.....

Wade... don't wire it to that drawing in post #34, else it could start without pressing start!

 

[Knobhead]

How?

The starter has to be reset.

Shouldn't be 230V control though.

 

[wade88]

230v control is what was present on the machine already. is 230v control a problem, or just not ideal? And if so, Tony how would i generate a 24v DC supply voltage from a three phase incoming supply? Would i need a DIN mountable transformer or something to generate my 24v control for the switches or is there something else. Been looking through RS but frankly not sure what im looking for.

I am a bell end. I just want a mini contactor with a 24v coil dont I

 

[wade88]

But i still need a 24V supply..... im going a little mad....and talking to myself at my desk....why is there a penguin under my desk? Who stole my electric wok......why can't i breath properly.

If this is in response to post#50 {wrt post #34} then the wire from 13 and linked from L3 (if I'm reading Wade's schem. correctly) goes to the unswitched side of the start contact, through the stop and pressure switch to A2 thus powering the coil if the pressure switch is/becomes closed!

I'm humble enough to be corrected though.

The schematic shows the control wired across 2 phases mate hence 415v not 230v

edit.
That's an old drawing and not relevant here I gather..........soz

With my eyesight i can hardly make anything out on that drawing. But it seems it's the wrong drawing.

WADE!
