Re: KF 700 spindle start up issue

Hi Jonathan,

I enjoyed working with you and learning about Andalusia ?

I confirmed with Felder that the brake board has no switch in the ground path, which could have explained the blowing of the fuse on the 24vac circuit.

If the fuse continues to blow with normal startup then the likely possibility is that the turn off suppression circuit of 1K1 or 1KS relays is compromised or bad.

Did you have any luck in reading the code? The flashes did not seem to have appropriate pauses for a 2 digit code. If you have a code, I should be able to find out what it means.

Hi all.
An update that may help someone in the future.

So after?lots of testing with the help of Imran of this parish, we established it was the 24v side that was causing the problem.
The spindle was running fine with no load, motor NOT heating up.
Everything was pointing to the start caps, which were both new.

The light on the board that should be constant after?start up, was flashing, this flashing was obviously?a code, maybe Felder know this code but was a mystery to me. If any body understands these codes it would be interesting?to know.

So as I don't?have easy access?to start run caps, we decided there was a chance that if we swapped?the caps around we would find something different happened. BINGO one of the caps has a fault and now it's starting and running under load.

New caps ordered from Jeffs Emporium,(the only place I could find them in Europe) he kindly emailed me after?I had paid, to say that delivery was over one month,Grrrrr.

If anybody has a source of quality caps in Mainland Europe please share.

The star here was Imran! I thank him again for helping, I couldn't have done it without him.?

I'm in the process of ordering new start and run caps.

Yes pulley is in correct?position.

Yes hold in the green button untill up to speed.....it blows the 24v fuse before it gets up to speed.?
This only occurs when the spindle is loaded.

I've have no issues with the spindle running with no load.

Fitted a new cap and still same issue, hopefully the new cap is bad, and the new batch will solve the problem.

Kindest regards

Question number one, are you on the correct speed setting? ( pulley)

Question two, are you holding the start button until it’s up to speed?


If yes to both of the above, it’s possible that you have a failed start, or run capacitor as both are engaged during starting.
