The Pauly PP2441 hole detector manual provides a general description of the device, its technical characteristics and the principle of operation. It explains how the transmitter emits infrared light through a hole in a strip and how the receiver and control unit generate an output signal.
The document includes ordering examples, assembly instructions, wiring diagrams, and detailed explanations of the control unit functions, including switch positions, potentiometer settings and power‑supply connections.
