Sharnoa SD 30 wiring diagram

I have a Sharnoa SD 30 with a Sharnoa tiger 4 control Ser# SE23835 that is based on a Lagun mill. I need a wiring diagram for this machine to repair it. It seems fully functional except that I can not get the drivers to lock on. The last company that had it let an inexperienced person work on the control box and they have left one 24 volt power line free and I can not figure out exactly where it should go and I really do not want to cause more damage than I repair. If any one has a wiring diagram for this machine I would really like to get a copy. Thanks

Did you get this sorted out?
If not I can try to help. We have the same machine.
