E-stop contactor not energizing

[john543]

My build mimics Marty's SYIL build it's wired the same as best as I can tell I just can't get the right contactor to finish it. The only part that not on the print is the contactor wiring.

And so is this.

[ShawnM]

What print are you following? What voltage are you switching with the contactor? 110v or 220v? I'm not following Marty's build.

Wire your incoming power into the L1, L2 and L3 (two hots and a neutral for 220 0 and just use L1 and L2 for 110 (hot and neutral). Wire whatever you want to power up to T1, T2 and T3. When you apply 24 VDC to A1 and A2 the contactor will latch and connect your incoming line power to whatever you have wired to the termination side. This make sense?

[john543]

This is the second one I was sent and was told it was 24 vdc

[ShawnM]

That's a contactor and it has a 220/240 coil. It says it right on the front. You wont use the NO contacts unless you need it to signal something else.

I was switching 74 vdc for Technic motors but Marty said my motors draw too much amps so he said run my 220vac through it instead.

Yeah it is they sent me the wrong part

[ShawnM]

Yes, they clearly sent you the wrong part.

What voltage powers the power supply for the motors? 220?

74 vdc whoops 220 powers the power supply

[john543]

Right now I have 220 single phase going into L1 L2
T1 &T2 power the power supply. L3 goes to common T3 goes to common side of relay6
NO contact goes to my C86ACCP.
A1 goes to common A2 goes to my E-stop switch
