Always use shielded twisted-pair cables for the load cells.
The unit typically uses the terminals for AC power. Ensure your ground (PE) is connected to a dedicated earth point to minimize electrical noise, which can interfere with sensitive load cell signals. Tension Detector (Load Cell) Input Terminals for the LX-TD sensors are highly sensitive.
On the rewind side, you often want tension to decrease as the roll diameter increases to prevent "telescoping" or crushing the core. The LE-30CTA allows for taper settings—start with a 10-20% taper for standard film. mitsubishi tension controller le 30 cta manual exclusive
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.
Ensure the left and right detectors are phased correctly so their signals add together rather than canceling each other out. Output Control Always use shielded twisted-pair cables for the load cells
Always ensure you download the official Mitsubishi Electric "IB" or "SH" document number for the LE-30CTA to ensure you have the correct wiring schematics for your specific revision.
