The Erhardt+Leimer DO 3001 is a sophisticated web guide system (often referred to as a web guiding controller) used in printing, packaging, and converting industries to keep material webs aligned.

Because Erhardt+Leimer manuals are copyrighted technical documents, I cannot provide a direct PDF download. However, I can provide a comprehensive operation and setup guide based on the standard functionality of the DO 3001 unit. or inductive sensors (e.g.

This guide covers the typical workflow, from wiring to calibration.

6. Manual Operation

Sometimes you need to move the guide frame manually (e.g., for threading the web).

Switch the mode selector to Manual.
Use the Left/Right arrow keys to jog the actuator frame to the desired position.
Note: The sensor is ignored in Manual mode.

Parameterization and Calibration

Unlike modern touch-screen controllers, the DO 3001 uses a parameter code system. 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.

Calibration procedure from the manual:

Disconnect actuator.
Set sensor at center of detection range.
Adjust offset trim until display reads “0” (or 5V out of 10V).
Reconnect actuator and run a manual full-stroke to verify no limit switch conflict.

Troubleshooting charts in the manual address common errors: “E-01” (sensor signal out of range), “E-02” (motor amplifier fault), “E-03” (limit switch active).

Signs of imminent failure (from the manual's maintenance log):

The "Zero" calibration drifts weekly (requires re-Potting).
LED segments flicker (power supply capacitor failing).
The manual indicates "Service life: 10 years under normal load." If yours is older, stock a spare.

Design and Build: Robustness in a Hostile Environment

The "Manual" for the Do 3001 highlights a device built for the "dusty, oily, and high-vibration" environment of a weaving mill.

1. The Sensor Head: The sensor itself is typically a small, modular unit designed to be mounted directly in the thread path, often near the bobbin or the pre-tensioner. It is constructed from high-grade, wear-resistant materials (often specialized ceramics or hardened metals) to ensure that the constant rubbing of abrasive yarns (like denim cotton or polyester) does not degrade the sensor's sensitivity over time.

2. The Control Housing: The Do 3001 unit usually consists of a rugged cast aluminum housing containing the evaluation electronics. Unlike modern touchscreens, units of this era often utilized potentiometers (adjustable knobs) and DIP switches for configuration. This analog adjustment method is a key feature of the Do 3001 manual:

Sensitivity Adjustment: The operator can tune how "hard" the sensor listens for the thread. This is crucial for switching between thick, fluffy yarns (which generate high friction signals) and fine, silky yarns (which require high sensitivity).
Delay Time: One of the most critical manual settings. The operator sets a delay window. This prevents the machine from registering a "false stop" during the split second when the weft insertion mechanism is picking up the thread but movement hasn't yet started.

Purpose and System Context

The DO 3001 is a digital web guide controller designed to actuate a guide roller or frame to maintain a defined web edge or centerline position. It receives signals from photoelectric, ultrasonic, or inductive sensors (e.g., E+L’s FR 55, FR 60, or similar) and drives a servo or AC motor via a power amplifier (often external, like the PA 60). The manual’s first chapters typically emphasize that the DO 3001 is not a stand-alone device but part of a closed-loop positioning system.

Typical applications from its era (late 1990s–mid 2000s):

Unwind/rewind edge guiding
Centerline guiding for adhesive tape or label stock
Line-following for printed registration marks
Laminating and slitting lines

7. Troubleshooting Common Issues

Part 1: What is the Erhardt-Leimer DO 3001?

Before we dissect the manual, we must understand the machine. The Erhardt-Leimer DO 3001 is a derivative of the famous DO 3000 series—a compact, high-precision digital edge controller used to guide moving webs (materials like foil, fabric, or rubber) so they run perfectly straight.

Unlike older analog controllers, the DO 3001 utilizes digital signal processing to interpret input from photoelectric or ultrasonic sensors. It then sends corrective signals to a proportional directional valve or an electric actuator, steering the web back to the desired path. It is most commonly found on:

Slitter-rewinders
Coating lines
Calenders
Laminators
Printing presses
