Re: Hammer C3-31 electrical problem

Usually, what you describe is electric brake related. You can take a look and see if you notice a burned component on the brake board. In my case it was a capacitor. In my electrical schematic there are connections shown to run machine with and without Ebrake. I ran mine without brake for a while until I repaired the board. It does require desoldering wires from the board.

?Hi All I thicknessed one piece of wood this morning. Turned it off. Noticed that there still remained a buzzing sound coming from the P/T. Didn't think any more of it. Changed tables out of thicknesser mode, fitted the rip fence etc ...changed the selector switch to table saw but it wouldn't fire up. Checked limit switches...all fine. Tried selector switch to P/T...buzzing sound again. Wouldn't fire up either. Three-phase supply from the rotary converter all good (power feed 3-phase works fine)...T'd off the Hammer feed. Gave Felder a call. Pity Jeremy left. Tech support was about as much use as a chocolate teapot. No idea on the buzzing sound (which I think is the key as that's 'new'). They suggested checking the internal wiring...looked for wiring diagram. Got back to machine and heard a faint click. Thermal overload trip...thinks I. And indeed it is. Table saw works fine. P/T works fine but the buzzing is still there and I am sure that if I leave the machine on long enough then that thermal trip will go again. But why ? If the machine hasn't been turned on then why the buzzing. And just a hint of hot electric smell. |
