Application Areas

The PFEA113-20 is widely utilized in continuous-web industries where precise tension control is critical to product quality. Key applications include:

• Paper & Board Mills: Controlling tension on high-speed paper machines, rewinders, and calenders.
• Steel & Metal Processing: Managing strip tension in pickling lines, rolling mills, and galvanizing lines.
• Converting & Packaging: Regulating web tension for film extrusion, laminating, and high-speed printing presses.
• Textiles: Ensuring consistent tension during fabric dyeing, finishing, and weaving processes.

Product Operating Instructions

The PFEA113-20 is designed for easy installation on a standard 35 mm DIN rail. Ensure the module is mounted in a well-ventilated control cabinet to maintain optimal operating temperatures. When wiring the load cells, use high-quality shielded cables to prevent electromagnetic interference from affecting the low-voltage sensor signals. The unit features a user-friendly front-panel display and a six-button keypad for manual configuration of load cell sensitivity, zero-set, and calibration parameters. For automated systems, the Profibus-DP interface allows for remote calibration and real-time tension data transmission. Regular maintenance should include checking the integrity of the sensor connections and verifying the zero-point calibration during machine downtime.

Q&A: Frequently Asked Questions

Q1: What is the benefit of the Profibus-DP interface on the PFEA113-20? A1: The Profibus-DP interface allows for digital integration into a control network, enabling remote diagnostics, parameter setting from a central HMI, and higher accuracy compared to traditional analog signaling.

Q2: Can this module handle more than two load cells? A2: No, the PFEA113-20 is a 2-channel unit. If a machine requires monitoring for more than two load cells, multiple PFEA units must be installed and networked.

Q3: Does the PFEA113-20 support both voltage and current outputs? A3: Yes, the two analog outputs are independently configurable for either voltage (0–10 V) or current (0/4–20 mA) through the internal software menu.
