: Always turn OFF all phases of the external power supply before installation or wiring to prevent electric shock or equipment failure.
Keep the controller enclosure closed. Powder clutch abrasion creates metallic dust that can short-circuit internal boards.
: Perform Class D grounding (resistance of 100Ω or less) and avoid common grounding with high-voltage electrical systems.

Compatible with LX-TD type tension detectors (load cells). Output Control:
: The unit utilizes real-time digital signal processing to maintain tension within tight tolerances (±1–2%), adjusting outputs within milliseconds to prevent material breakage or slack. Dual Mode Operation : It supports both Automatic mode (using feedback from sensors like the LX-TD series) and Manual mode for setup and troubleshooting. Output Versatility : It can output a 0~24V control voltage for magnetic particle clutches/brakes or a 0~5V torque command for AC servo amplifiers. Integrated Functions
Use the front-panel dial or buttons to set your . This is the exact Newtons or Kilograms of force you want the machine to maintain throughout the run. 💡 Pro-Tips for Peak Performance : Always turn OFF all phases of the
Before modifying your machinery, ensure the hardware specifications of the LE-30CTA match your system requirements. 100V to 240V AC, 50/60 Hz.
Incorrect PID tuning parameters, mechanical binding in the roller bearings, or excessive mechanical backlash.
Connect the AC power source (100-240V AC) to terminals and L2 (or L and N ). : Perform Class D grounding (resistance of 100Ω
: You can find listings at Radwell.com or various eBay sellers. Industrial Applications
The LE-30CTA is designed to maintain constant tension in web handling applications (film, paper, textiles). It achieves this by receiving a signal from a tension meter (Load Cell), comparing it to a set target tension, and outputting a control signal (voltage or current) to a brake, clutch, or motor drive.
| Parameter | Value | |-------------------|--------------------------------| | Power Supply | 100–120 VAC or 200–240 VAC (depending on variant) | | Control output | 0–10 VDC / 4–20 mA (configurable) | | Tension input | Load cell (mV/V) or DC voltage | | Display | 7-segment LED, 4 digits | | Setup parameters | Gain, zero, taper, response time |
The current drawn by the connected powder clutch or brake exceeds 2.4A, typically due to a shorted internal coil.
Nullifies the physical weight of the roller assembly (tare weight).
