Reversing 1ph motor

[hotponyshoes]

If the contact blocks in the pendant are rated for the motor load and there is room to stack another pair of N/O on the back of the existing ones then that's how I'd do it.
Those contact blocks can often be clipped onto each other to give extra poles.

To do it with just the hardware you have you'll need a bit of 4 core cable to run to the pendant.

Incoming mains connected to U1 & U2.
Remove the link bar.
Remove the link from X5 to Z*
Using the 4 core:
Connect from U1 to #3 on the white button.
Connect from X5 to #2 on the white button
Connect from Z1 to # 4 on the white button
Connect from Z2 to # 4 on the black button
Get some single bits of cable and connect the pendant terminals together:
White Button #1 to White Button #4
White Button #2 to Black Button #2
White Button #3 to Black Button #3
Black Button #1 to Black Button #4

Somebody might want to draw this out and check it first!!
Also, this will go bang if you press both buttons at the same time which you could prevent by sourcing a couple of extra N/O contact blocks.
I suppose you could just add a quick blow fuse somewhere just incase you drop the pendant and both buttons get pressed at the same time.

Thanks for all the bits of info for various ways to wire it up.

I'm going to go with a reversing contactor operated by the pendant.

I'll take a pic if it all blows up.

This turned up this morning.

Will this not leave that winding getting power all the time? Or do the windings connect U1-Z1 & U2-Z2?

240v pull down coil?

240v pull down coil?

Yes

That's going to be more complicated than the change over switch.

Quick sketch

I was thinking that the pendant arrangement would be more user friendly.
It's going to be at the end of 7-8m of cable incase i have to wrestle with the end of a bit of steel as it starts through the roller.
I can operate it one handed. If i get dragged in or pinned to the wall by a bit of steel i can just let go of the pendant and it stops. A change over switch on the end of a bit of cable might need two hands to operate.
The contactor might even allow me to use some sort of electrical device and different pendant to push down the middle roller instead of threaded bar.

The contactor might even allow me to use some sort of electrical device and different pendant to push down the middle roller instead of threaded bar.

I have often thought it would be nice to have a feature like that on my bead roller,
Either a remote adjuster or something that winds down a bit each time you change direction automatically.
A ratchet on the threaded bar and a solonide driven by the fwd/rev push buttons might do the trick. If the solonide gave 1 click pet press you could joggle the fwd/rev buttons at the end of the run to get the depth you wanted.
I think you might be able to do it simpler than a remote control though, just some sort of spring loaded twiddler or adjustable clutched motor might do the job? By keeping a constant pressure trying to turn the thread it should just wind itself down as required?
