Always use shielded twisted-pair cables for load cell wiring. Ground the shield at the controller side only to prevent ground loops. Control Output Wiring
| 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. | mitsubishi tension controller le 30 cta Manual
Select and execute. The controller scales its internal voltage readings against this reference weight. Remove the calibration rope and weight. 4. Parameter Configuration and Tuning Always use shielded twisted-pair cables for load cell wiring
If the tension is oscillating (bouncing up and down) or reacting too slowly, you need to adjust the PID parameters. | | Tension reading drifts | Zero calibration
: Perform Class D grounding (resistance of 100Ω or less) and avoid common grounding with high-voltage electrical systems.
This controller is essential for industries where material integrity is critical to the final product's quality: : Prevents color misregistration and web breaks.
Generally designed for industrial voltages (often single-phase or low-voltage DC).
