Hi Tom, thanks that helps. Were you having the same symptoms as Hoover? The contactor would only work if you pushed the button
but the coil wouldn't pull it?

ps Hoover I suspect the coil has failed somehow, probably gone high resistance. If you have an ohmmeter you could compare the readings of both coils (shut off the power and disconnect the coil wires) to verify the problem for sure

this is very encouraging. I can make a new enclosure box easily enough. I do a lot of sheetmetal fabrication projects for a friend that is an electrical guy- bartering is the best!
I will compare resistance in the two. it didn't even occur to me to try that.

thanks again!
 
Hi Hoover, yes you could certainly fab a new box - you mentioned the transformer is not being used on yours, you could remove it, but if you decide you wanted to run your lathe on 220 volt you would need it.
At least now you have a part # for a possible replacement contactor- I believe Allen Bradley also makes some that are 5 pole, if I can find the data sheet I'll post it here

Yes, in that I had to use the button to engage the contacts. Ultimately the problem was the contactor itself, not the coil.
 
6 Pole contactor

You can also get a 4 pole (DPA34 is a 4 pole 30A contactor) and add an auxiliary contact on the side or top as indicated above. You need to map out/label the wires and if the additional two terminals are NO/NC. The auxiliary contactor below adds a NC/NO set of contacts. You can also call a distributor or tech support if you need assistance in the contactor parts.

You also might try calling some of the machinery distributors like Eisen or Acer.

Thanks for all of the advice!
It turned out to be some corrosion on the faces of the magnets.
The contactor bench rests perfectly now.
 
Ah! (slaps forehead) another mystery solved- I had a feeling that unit was still good, glad you found the problem
