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
Dmhughes is up to date on these and he will know better than i.

If your drive was bad, you'd get a 26 fault. Make sure your start permit light is not on when you're not trying to run. If it is, trace is out on the prints. go to 4_1 and check what mode it's in.
What's the LCE230 board? Are you in United Stated?
Did you replace the board with the same version, was it G01 G02, was the problem on before you changed it if so why did you change it?
Dave
is it possible fix that errors 0021 and 0102?
So when a lift plays up,,what do u do,,,yep,,diy! Get a lift engineer in,,please!
