Re: Felder Bf6-31 compact. Motor brake gone pop
|
Hi Alex,
Correct, this schematic is for 2KW but for one w/o brake function. If the motors are starting up and running normally then capacitors are good.
My schematic has a date (bottom left) 15.09.1994. I cannot read the date on your schematic but I assume it is older because your machine does not show the low voltage transformer. So all switches are 220VAC vs ~24VAC in newer machines including the schematic I have dated 1994.
If you machine has/had braking function then the schematic is not correct. I was fine for capacitors purpose. You should request a sch for your machine with brake function.

Hi Imran,?
I¡¯ve managed to find the big book, but it¡¯s only a spare parts book. However a capacitor replacement a while back (just one replaced) instigated a request for the wiring diagram from felder for this 2kw machine : ?I will replace the other capacitor
which I have to see if that rectifies the problem when I get time and see where we go from there.?
Thanks?

? No Worries Alex. Is your machine ~5KW? If so, I see Y-D start which adds more relays; K4 is one of them. There is no K4 in the first schematic I shared which was for a 2KW machine.
Do you have the big book of your machine? The schematics and other important info is in there. Here are couple of shots to show you what is in the book that I have.

If you do not have the machine book with wiring diagram info as shown above, I suggest you contact Felder and get a copy. They may be able to guide you as well as to the location of the relays.
The pics you shared are not very sharp. Appears there is at least one more relay by the selector switch. Still it would be difficult to guide you because I do not know where these are located and for that matter if my schematic matches your machine in
the first place.
Once you have the wiring diagram and you poke around a bit more to try to locate components, I can try to help.

? Hi Imran,?
Sorry for the late response, just found your message in my junk ! Thanks for the wiring diagram , most useful as I seem to have misplaced mine. Looking on the circuit board, I could only find K1 and K4 and the other connecting block visible from the top
where the capacitors feed into. There is nothing on the circuit board where the K2 and K3 markings are. Do you know if the circuit board is serviceable or do I replace the whole unit ??
Thanks?

? Hi Alex,
Yes, a wiring diagram. Sharing what I have but you should have a copy of yours. Now a days, it is placed in a pouch on the inside face of the electrical cabinet cover but not sure what they did back then.

?Hello Imran,
thanks for your kind response. ?I¡¯ll have a look for those components you mention tomorrow. I¡¯m not an electrician, although my brother is and if I can make it easier for him, all the better. I¡¯m guessing a schematic is a wiring diagram ?
Many thanks?
Alex
