With no material on the rollers, use the "Zero" potentiometer or menu setting. This tells the controller that the current weight of the roller equals "0" tension.

The controller continuously calculates the roll diameter using:

on the tension controller side. It is strictly forbidden to share a common ground with strong electrical power systems. Noise Mitigation: Control lines should be laid at least 100mm (3.94") away from main power lines to prevent signal noise. Enclosure Requirements: | Model | Display Language | Primary Application

For DIN rail mounting, ensure adequate clearance around the unit for airflow and wiring access. When mounting in a control cabinet, verify that internal cabinet temperatures remain within the specified 0–40°C operating range.

Usually indicates a broken wire in the load cell circuit or a sensor that has gone out of range.

The official Mitsubishi LE-30CTA manual is comprehensive, often running over a hundred pages. It covers everything from technical specifications to detailed wiring diagrams. Below is a structured summary of the core sections found in the manual. 1. Installation and Wiring This tells the controller that the current weight

| Param | Name | Exclusive Setting Advice | | :--- | :--- | :--- | | | Target Tension Unit | 0=kg, 1=N, 2=lb. Change only with no roll loaded. | | F01 | Max Tension Range | Set to 120% of your max operating tension. Exclusive: Prevents ADC saturation. | | F02 | Load Cell Sensitivity (mV/V) | Enter value exactly from load cell certificate. Even 0.1 error causes 5% reading drift. | | F05 | Proportional Gain (P) | Start at 2.0. Low inertia webs (film) need <1.5. Heavy paper >3.0. | | F06 | Integral Time (I) | Start at 2.0 seconds. Too low = hunting. Too high = sag response. | | F10 | Dancer Pot Range (0-10V) | Exclusive: Set to 10.00 only if using full 330-degree pot. For 270-degree, calculate (270/330)*10. | | F23 | Soft Start Time | Ramp setpoint over 3–10 sec. Exclusive: For elastic webs (stretch film), use 8 seconds minimum. | | F31 | Zero Calibration Offset | Run with no web. Press SET for 2 sec. Do NOT do this with load cell pre-tension. | | F40 | RS-485 Station Address | Default = 01. Exclusive: For multi-zone systems, each LE-30CTA must have unique address. |

LX-TD type strain-gauge load cells (2 channels). Control Output: Analog output: 0–10V DC, 4–20mA.
