  "notes": "Generic v1.126 example (not tied to one scene). A conveyor carries bottles from an inspection sensor through eight tracked positions; the reject station is at position 6. X1 = infeed photo-eye, ON once per bottle (the shift pulse). X2 = inspection reject sensor, ON = bad bottle. X3 = Reset PB (N.O.). X4 = reject confirm photo-eye at the reject station. C1-C8 = BSL tracking register, one bit per bottle position (C1 = the bottle just inspected). C9 = unload bit: the bit leaving position 8. Y1 = reject solenoid (on while a bad-bottle bit is at position 6). Y2 = missed-reject alarm (latched when a bad-bottle bit leaves the tracked zone).",
