Hello,??????????
I am Jonathan, nice to meet you.
I recently acquired a Felder CF731 from 2001 (three-phased powered, with electrical braking of the motors, I do not have digital control of the height/angles of the tools nor any electrical speed control of the motors). I got it from a person who passed away, so I cannot get any info from the previous owner.
Unfortunately, I cannot start the machine. Any support would be a great help.
When I switch on the machine in reverse shaper mode, the yellow light does not light up. I checked all the security switches (saw cover, planer table and planer dust collector) and all stop buttons. All are working fine and to make 100% sure, I short-circuited them. I also checked the yellow light bulb and it is working well.
I checked the main On/Off switch and the ¡°shaper/planer/saw¡± selector and they are working fine.
There is current going to the board and there is a green LED lighted up close to the microcontroller PIC on the board (not sure about the meaning of this LED, I suppose it is showing that the 24V power supply to the microcontroller is working well??)
I checked the 2 relays on my board (one called ¡°K1¡± for the start of the motor and one called ¡°K4¡± for the braking when motor is stopped, in my understanding) and I noticed that they are different, so I assume that one/or both relays were changed by the previous owner. I noticed a strange thing there:
The relays have 4 in/out connections, 3 are for the 3 phases and are NC (normally closed), one is for the activation of the relay (A1/A2) and one called NC or NO that is (I presume) used to know the state of the relay? (open or closed). I¡¯ll call that last connection the ¡°state control connection¡±. I noticed that the relay for the start of the motor has a ¡°state control connection¡± which is NO (Normally Open) but the relay for the braking is a NC (Normally Closed). I think that both relays are originally supposed to be the same and that the previous owner made a mistake when replacing one?? Also, what about the orientations of the connections, he might have made a mistake, too.
Can anyone who have a similar machine check on his board and confirm the connection of the relays K1 and K4 and the type of the ¡°state control connection¡± (NC or NO). (Note: sometimes the two extremities of the C from ¡°NC¡± are almost touching each other, making it is easy to mix that letter with a O. Better to check with a multimeter if not sure)
My board is a Siemens C98451-D6094-P10-2-86 (number engraved on the board) or C98451-D6094-A20-02-22 (number written on the white label sticked on the board).
Also, if by chance somebody have the electrical drawing of the board (not the connection drawing provided by Felder with the machine, but the one of the board circuit), it would also be helpful!
Thanks so much for your support,
Best regards,
Jonathan
