Re: Electrical Problem with CF731 Pro
¿ªÔÆÌåÓýGreg, For switches, just use the continuity test. Each ON and OFF switch has a redundant terminal on my machine. Just put the meter probes in the unused holes and look for short (red NC) or open (green NO). Also check for state change when the button is pushed. Per my other msg, switch fault is not my first choice because they have gone bad on mine (start sw) but it does not create the situation where power cycle is needed.

?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! |
