Hi guys I have an old kone mono space I think the first version g01 with the v3f16es drive. My colleague turned the lift off while servicing and after powering on could not drive and would only get the error of 5 unsuccessful starting attempts which I think was 0051 from my memory.
We have checked all safety circuit inputs to lce 230 and all are fine. We are not able to get the main contactor relay on this board to energise which supplies a ground to a2 of the drive contactors. We replaced the lce230 board but still the same problem. Even if we jumper that contact while trying to drive on rdf or auto, the contactors will pull in but lift won't drive. We will also get the start permit and main contactor LEDs to light up on processor if we do this.
This seems to be a drive problem but we have no errors 0026 and drive ok led on processor is up. Mcen led on drive board is not lighting up either even if we jump the ground to the main contactors. I was thinking perhaps the control board of the drive could be the problem? Is there an output from the drive that pulls in the main contactor relay on lce230 board?
Any help I can get would be greatly appreciated. Cheers
