Siemens Mag Starter WS10-2301P : Compressor Wiring

[mwalt91]

First off , let me say thanks to all those who have posted on this subject in the past. Im not an electrical guy but I was able to learn a ton off of old post. It has gotten me to where I am today with this project.

I’m trying to wire up my compressor that is run with a 1PH Baldor 10HP electric motor. I am having trouble getting the magstarter ( Siemens WS10-2301P) wiring configuration correct. I have attached some photos and my own wire diagram with the starter specs. Basically when I turn the switch to Auto or Hand, the coil engages, but all I get is a humm, and the motor doesn't start. I know it’s not my start or run capacitors for two reason ( 1. They are brand new 2. If I wire directly from the panel and throw the breaker on, the compressor/motor starts right up and runs fine ). SO I am guessing I have something wrong with my starter wiring.

Any help would be appreciated. I plan on talking with a electrical engineer buddy today but I know there are a lot of guys on here with a wealth of knowledge on this subject and may be able to steer me in the right direction. Thanks in advance

Sorry but your pics are way out of focus to be of use to me! Where is the humm coming from - motor or coil? If its the coil, check coil voltage - rated 220v? or is there junk in the region where the contactor gets pulled in - like wire insulation scraps? Do you have the wiring diagram from the mfr? If so scan it and post (in focus).
Disconnect motor at t1/t2 and turn on starter - humm?. Is there 220v at t1/t2?, 110v t1 to ground, 110v t2 to ground. let us know what you find.

It looks like it's wired correctly from you diagram, but it's hard to tell for sure in your pictures! Take an non-metallic tool and press in the contactor block "button" (the small black square in the center of the contactor) to see if it starts. If so there is some problem with your coil or its wiring. If not look at the overload to make sure its not tripped.
