| Symptom | Likely Cause (via manual) | Solution | | :--- | :--- | :--- | | | Faulty sensor or excitation voltage missing | Measure between terminals 6 & 7; should be 5V DC. | | Tension reading drifts | Zero calibration not done after warm-up | Let unit run 15 min, repeat Zero/Span (Sec 5.2). | | Output always max | Broken analog output transistor or mis-set DIP switch for output direction | Check DIP switch #3. If correct, measure output at terminals 10-11. | | Erratic reading during acceleration | Incorrect damping setting | Increase "Damper" pot (labeled DAMP) per manual Section 7.3. | | "OL" on display | Overload – tension exceeds sensor range | Remove load. Check for mechanical binding. | In industrial plants, the tension controller is often
