@BlindViper

I did some poking around and found a thread over at PM.

has a link off to dropbox with several manuals available.

I hope that helps!

Thank you.

These manuals are the ones I have. The only wiring diagram in them doesn't match my lathe options.

The pictures would indicate that not much is left of the original control system and that it has been completely rewired and pretty poorly at that. My question would be if it worked before on a static converter that nothing would change by adding an idler RPC, it still would have been wired the same. If your intent is to replicate the original design, I would replace everything, as the current condition of the wiring/switch gear would be of concern. On the 2 speed motor, typically people incorporate a separate motor switch to change the motor speed ranges, larger machine may use contactors which is a bit more complicated.

The 2nd speed is what I was after. I believe all of the original wiring is in place. The other issue was the "electrical" compartment cover. Which was a DOT truck placard frame and insert.

I rarely try to figure out what others may have done- i’ve seen too many “fixes” .
When in question, i’ll rip everything out and start from scratch.
I have designed a few types of control systems that are used for meat processing machinery and packaging equipment.
Regardless of the manufacturer, control systems are used for turning motors on and off by using small amounts of current to operate electromagnetic coils, that operate relays and/or contactors , that in turn control larger amounts of current.
If I were to retrofit, I’d wire up 4 contactors (2-40 amp , 2-25 amp ( Fwd, Reverse {interlocking}, Low Speed, High Speed) I would use the apron switch for directional control .
A maintained contact contact switch would be used for high and low speed control.
I would simplify the control circuit by the use of 220v coils in the contactors, and use the fused potential from a hot leg through the switch and control circuit, another fused hot leg would be common to the contactor coils.
Provision for an ESTOP, and a jog button could easily be wired in.

Something like this...



this is the line inputs and contactor power cable layout only
control circuit to be outlined soon

here's the 208-230VAC control system i'd use for the drawing above.

its interlocked and provides forward, reverse,high speed, low speed and e-stop.
a jog button can easily be added upon request...
