Topic tags/keywords: powermatic model 66 table saw Hello- I just bought a PM model 66 5hp 1 phase, when I plug it in it is as if the Start button is pushed in. If I push the Stop button in it won’t stick/stay Off. If I hold the Stop button in it will turn off until I release the Stop button, on release it starts back up running. My thought it is setup not to utilize the push buttons, is there a simple diagram that shows the different configurations of this panel? I will attempt to attach pics to show my panel. Thanks in advance for any & all info. |

Sounds very dangerous. I would guess a defective switch. Is it a magnetic switch? -- I admit to being an adrenaline junky; fortunately, I'm very easily frightened |

I agree. Sounds like you need a whole new switch setup. I truly envy you finding a T66. My dream table saw. |

My thought it is setup not to utilize the push buttons, is there a simple diagram that shows the different configurations of this panel? It sounds like it’s been wired to keep the solenoid in the starter energized continuously – which could be used in conjunction with some external switches; but that is certainly not typical or recommended. Is this a new to you machine? Did it work properly before and if so, what changed? There should be a block wiring diagram on the inside cover of the starter. If not, let us know the make/mfg of the starter and maybe someone can pull something up for you. Cheers, -- Brad in FL - In Dog I trust... everything else is questionable |

Thanks for all of the replies so far. This is new to me but far from being brand new. I am attaching a few more pics, I didn’t think to look at the backside of the front panel when I opened it to take the internal pics. It looks like there are switch configuration options (based on these new pics). If anyone has any experience or can interpret this diagram & explain which or what configuration my current wiring is I would be very grateful. |

There is an electromagnet that pulls the contacts closed until the off button is pushed and then it de energizes. Sounds like the magnetic coil is open. A new magnetic starter is probably needed. |

Thanks again for the continued contributions. I am going to approach this slightly different, I am hoping someone can label my pic with connection descriptions OR fill in the “Connect A to….” “Connect B to….” etc etc. The pics show how it is currently connected, but I am assuming it is not correct. Connect A to |

I spent time on the phone & a handful of emails with Powermatic, there isn’t a wire diagram available for this. Thanks |

See in your picture 3rd frame right side wiring diagram, point#3. The left side push button is the start, the right side is the stop, under the start see the open contact? When you push start the power flows through the stop to the coil of the starter, on the starter is that normally open contact (probably on on side or other) that has to close when the magnet pulls in the 240v power to the motor, when it closes it bypasses the on switch and keeps power flowing to the coil of the starter.
See your “B” and “F” it looks like it should be wired “B” to “A”. Need a better picture. |

Solved, cost = $0.00 Take jumper out of F, put into A. |

I am hoping someone can help out on this one- For a Baldor 5hp 1Ph- does anyone have a pic they can post of how their Start & Run Capacitors are hooked up? If you can note the Letters or Numbers on each wire, even better. I will post more detail soon, but I wanted to get the SOS going ASAP. Thanks |

When I had a similar problem with a motor (in fact, I had blown the capacitor by mis-wiring it), I took it to a local motor shop, and they had a new cap installed in about 5 minutes, for a charge of $15. Well worth it. And they showed me how to wire it (numbered wires, like yours; I had never seen that before, being used to color coded wiring). -- I admit to being an adrenaline junky; fortunately, I'm very easily frightened |

I found the correct Baldor wiring diagram, this confirmed I had replaced & reconnected the capacitors correctly. Using the wiring diagram, it was obvious that the manual reset button was bad. A new switch is on order. FYI, the button was not popped out. When I opened up the motor I noticed the centrifugal switch had previous damage and had been repaired (w/ super glue), so I ordered a new one. Opening up this motor & doing some basic wiring checks was a good learning experience. I am very surprised just how simple these motors are. |

Bunch of helpful people on this forum and with the internet – there isn’t much you can’t figure out. -- Bob, FL Keys |
