Re: Failed engine brake 220v single phase C3-31
¿ªÔÆÌåÓýHi Brian, For my machine a single ground wire needs added to bypass the brake board. That is, if the brake board is removed this wire needs to be added to run my machine. Check your schematic it should show a dotted line with verbiage of Ohne Bremse or something Bremse. As for repairing, it is easy to detect when a part is cracked open although no guarantees that something else that visually looks okay isn¡¯t bad. I can take a pic of the new board installed in the KF it is still about 20 Yrs old because brake board failed rather early in the life of the machine. I remember it being identical. I am still curious about the diode on the back side of your board. Are you the original owner? You can also compare your board to mine to see if a diode is missing from topside and it was easier to place it on the bottom due to tall components each side. I did do a quick check and the vias used to solder the diode on the back side do not have a diode on the top side on my board. However, it might still be connected between the same electrical nodes as one on the top side. Imran Malik On Jul 26, 2023, at 2:13 PM, ibsenafshar <brian@...> wrote:
?Imran, you are being incredibly helpful. My part number is exactly the same. There is a repair shop I use to repair large (40 amp) electronic dimming modules that fail at about 20 years due to capacitors aging out. Drawback is they take a long time to get to it. Do you think the saw will run if I remove the board to have it repaired? Or is there an easy way to jump around it? I've sent this info to FelderHQ in Austria. <STICKER.jpg>
