The assembly of the pickup PCB takes place on the original fastening spots of the original plate.
The adjustment is made only on one cylinder, the others fits automatically via the given distance of the light barriers. A small LED near every light barrier shows the correct position during the adjustment. Each cylinder has its own independent ignition, i.e. three microcontrollers for three cylinders, therefore also three light barriers. The advantage is the separately exactly computed advance for each cylinder. (ZDG3.3).
