Hoping someone out there can give me a hint or two what I might be doing wrong. I'm using PJ's diagram that he did for Johnodon's EBIAB build (diagram in this thread: https://www.homebrewtalk.com/f170/a...ssel-single-pump-illuminated-switches-264251/). I've got everything wired up and tried it out today. Pump outlet worked great and the PID worked perfectly as well. But when I hit the switch for the element (the one controlling the contactor) it made a god awful buzzing. Not a normal buzz, but an extremely loud one that you can't think with it going on. And I'm pretty sure the outlet didn't power on either because the element did not start seem to get hot. I tried switching it on and off a few times since I found that in the forums. Didn't help at all.
I checked the schematic again and it looks like I have the 40 amp 2 pole 240V Auber contactor connected properly - I check continuity to the outlet, power, and SSR. I checked continuity to the switch and the neutral on both sides of the coil and it looked good there too. For the power side of the coil, I just ran each of the two from X2 and 24 on the switch each of the two spades on the same side.
I'm at a loss what might be wrong. Any ideas? Is mounting the contactor directly to the Auber project box causing an issue? I've got it locked down with machine screws through the box and nuts on the inside.
Thanks for any help.
