This is where the manual pays for itself. The DO 3001 has 28 terminal pins. The manual provides the critical pin-out guide:
In textile, paper, and film converting, precise web guiding is critical. The Erhardt+Leimer (E+L) DO 3001 digital sensor is a cornerstone technology for edge detection and web positioning. This comprehensive technical guide serves as an operational reference for engineering, maintenance, and production teams working with the E+L DO 3001 system. 1.

The front panel typically features:
Unlike modern touch-screen controllers, the DO 3001 uses a . The manual includes a table of numeric codes (e.g., P01 = proportional gain, P02 = integral time, P03 = deadband width, P04 = sensor type selection). To change a parameter, the user holds a “Set” or “Prog” button, enters a code via arrow keys, and adjusts the value.
IP65 rated, offering robust protection against dust and water splashes in harsh industrial environments. 2. Installation and Mechanical Mounting
– After centering the web manually, pressing “Teach” stores the current sensor voltage as the setpoint. Some DO 3001 versions allow edge or center teaching.
