I have problems with the light curtains on my TP9-2. I have disabled the curtain boards with a jumper as shown in this thread before, but the systems still identify the curtains as affected. Do someone has any idea where to start looking? Can someone share the schematics related to the light curtain circuit?
The machine was working properly before is was moved to a new location, some parts was dissembled to be able to move the machine.
Thanks in advance!
I had the same problem make sure all the Black (transistors) are all straight on both sides on the light curtain boards. I had one that was pointing down just a bit.
