Alex,

I have a schematic of single phase BF6-31 but your machine should have a schematic that would be best to use.

Both single and 3 phase BF6-31 show use of transformer T2, P1 Rectifier and Relay K6 for braking function. Apparently this is before the current era of using electronics implemented on a circuit board.

Felder usually labels all major parts. If you can located T2 and K6 in your electrical cabinet, we can troubleshoot. I am assuming that you are comfortable carrying out this kind of exercise. If not, an electrician should be able to check these 3 components. The part numbers for these components are in your schematic.

Let me know if you need any further assistance.

Hi all, it’s a first post on this forum for me. I have the above machine and have enjoyed using it for quite a few years. It’s 25 years old, single phase, built like a tank and is a great tool, but it’s suddenly developed an issue with the braking system. The normal noise when braking was amplified and didn’t stop until it had tripped the rcd. I’d be interested to hear from anyone that may have knowledge of this kind of problem or perhaps experienced the same thing please ?
?Thanks,
Alex
