AC unit -> rotary phase converter?

ICR is only picked up momentarily for the start operation MC1 is the main three ph contactor. 1CR is just any small control relay with a 220vac coil. You also need an auxiliary retaining contact on MC1.
The start PB only needs to be held for less than a second otherwise you may trip the O.L.
BTW Looking at the schematic again, it is a bit misleading as I have a corrected version, 1M,MC1 & MCR are one and the same, 1CR is separate.

Does 1CR have 2 seperate contacts? One from 12 to l3 thru cap and one to MC1.

Thanks for the help.

Yes, it operates the start cap momentarily and initializes the pick up of MC1.

I made a diagram last night. Here it is. Can I do it like this? The one momentary button turns on both the startup coil and the motor contactor. I want to add the light across the motor contactor relay. BTW I'll be running a 1hp mill off this.
