Grain loading machine wiring

You can't blame the customer normally, it's no their job to know the standards but judging by the gear inside the control panel it's has been modified not too long ago ( within last decade) whether it follows the regulations is another thing, but if they followed the original wiring plans then they are obviously not competent to do any replacements or upgrades.

Unfortunately DW, the law requires that it is the responsibility of the end user to confirm that the CE marking is correct.
I have been involved with two PN's from HSE in the last year where the end user did not ensure that the CE marking was correct, and got a PN for their lack of attention to detail.
It put one of them out of business!
The other also had the first ever IN I have come across for fixed wiring I&T as in EIC & EICR under BS7671!
This is still ongoing.

I agree with all the above safety first, but you could drop motor out of Overload & then do some tests, check E/Stops then work through diagram looks simple enough with coil information & following the route of your auto SW.
at least you have a drawing to follow might not be the best or even have a CE mark but you do have a drawing.
if you manage to get it to work does not mean you have to put it back into service, you could advise it is dangerous or does not conform get client to sign to that affect.
but you might solve the problem.
