E-stop contactor not energizing

[john543]

The machine is a Birmingham mill which cnc masters modified for cnc, I'm re-modifying as to all the steps it kept missing.
Using Technics clearpath motors part numbers in the parts list.

This maybe a bad part but am asking if I may have wired it wrong.
I have a Eaton DIL M9-10 220 50hz 240 60hz contactor I have the 240 hooked to L1 & L2 out T1 & T2 going to my Technics power supply
T3 run to e-stop and then to the stop relay and L3 goes to common
A1 to common A2 to my VFD
NO contact goes to the C86ACCP
I have a quencharc suppressor connected to A1 & A2

Here's the skinny I power up the control and VFD, turn on the PC it does it's thing connects to Acorn all's good so I clear the
reset and the contactor doesn't pull in, but I can push it in and then everything works.
Defective contactor?
Or my wiring?

Are they wired in parallel or in series...? I had a similar problem when wired in series. When I wired them in parallel they snap shut !

Well as I'm not an electrician I wired it the same way as I did the 24v contactor, reason I change the contactor t1 & t2 we're opposite each other one was NO the other was NC didn't see that when I purchased it. Now I got a 220/240 contactor wired the same except I'm using 220v instead of 24v. The 24vdc contactor worked but t1 & t2 it didn't power up my power supply to my servos.

220 vac comes in on L1 & L2 comes out T1 & T2 I would think that's parallel.

I asked the wrong question...for your situation. I have multiple contactors, including an E-Stop and they are activated with 24vdc. My 24 volt supply could not activate them when connected in series. In my setup 24vdc from a power supply goes to A2 and 24v COM goes to A1. For a simple check Connect the proper voltage to A2 to ensure it will activate.

When he asked about series or parallel he was referring to the coils on the contactors, not the Line or Termination contacts. There is no series or parallel for those. You have your Line coming in on L1, L2 and L3 and the Termination (or load) wired to T1, T2 and T3. A1 and A2 is the coil and they can be many different voltages. You can wire multiple contactor coils that need to latch at the same time in parallel.

It's best practice to use a separate 24 VDC power supply than the one powering the Acorn, If you are using 24 VDC contactors. Make sure you add snubbers to all your AC coil contactors. My current retrofit/build uses Siemens 3 pole, 120vac coil contactors with snubbers built in.

You clearly have the contactor wired wrong.

Thanks Shawn
I do have a snuber between A1 & A2. It was working when I had a 24vdc contactor, whole problem was the contactor was the wrong kind see picture. 13 & 14 should be NC but it's NO didn't see that when I ordered and the second one I ordered they said it was 24vdc but on fact it was 220 vac.
Also I do have two 24vdc power supply's in the list of parts.

So your saying I Should run 220 through A1 & A2? That's where I have the E-stop connected sounds like a lot volts for that E-stop switch.

That's not a contactor it's a 24 VDC relay.

Your talking to a Machinist not an Electrician
I've just ordered a 24vdc contactor for the third time. This time it says 24vdc and has L1 L2 L3 NO and A1 across the top, T1 T2 T3 NO A2 across the bottom

[ShawnM]

Either way, did you want a relay or a contactor? What are you trying to do? In your first post you wrote "I have a Eaton DIL M9-10 220 50hz 240 60hz contactor" In your picture you're holding a Eaton DIL A-22 XTRE10B22 which is a relay. Did you not Google the part number?

Again, what are you trying to accomplish?

You mention T1 and T2 and L1 and L2, those terminal are not even on the relay.

That's a contactor.
