Re: Electrical Problem with CF731 Pro
¿ªÔÆÌåÓýGreg, From what I gather, for each motor circuit, there is a connector between the selector switch and the motor. This is where you plugged shaper motor into table saw cable from selector switch and it did not work. Similarly, tablesaw motor plugged into the shaper cable from selector switch worked. To me this shows that the issue is between the selector switch and the cable connector on the table saw circuit. Check the connector to ensure pins are not bent and shorted (I do not know if this is possible as I do not know what the inside of this connector looks like). Check each wire from this connector, all the way to the selector switch to make sure wire insulation is not compromised resulting in a short between wires or between a wire and machine chassis. I am assuming there is nothing but wire between selector switch and this connector. If there is another component (relay, etc) then that needs to be checked out.

?Hi Imran, What is the connector? I took the wires off the stop switches for my table saw (the factory installed switch and one I installed to operate the saw from the sliding table).? With the wires dangling, as expected, the entire machine would not operate.? It was as if the a stop button was N/O.? I then tied the wires together, avoiding the switches, and, just as expected, the same malfunction occurred.? I did notice, however, that the K-2 relay closed.? But K-1, which is downstream and latches to send the 3 phases to the motors, did not close, so no action on that motor. Will the strangeness ever cease. Tomorrow, time permitting, I'm going to review every wire that I diagrammed to see where the "as is" diverges from the Felder wiring diagram. Thanks again, Imran! |
