Working Principle:
The PFEA111-65 processes the raw signal from force sensors, applying mathematical models to derive true web tension. It compensates for factors like roller bearing friction and web inertia. The final calculated tension value is output as a stable analog signal, allowing the drive or controller to adjust motor torque precisely to maintain constant tension.

Installation Requirements:

  • Power Supply: Verify the required power supply voltage matches the “65” variant specifications.
  • Sensor Connection: Follow the wiring diagram precisely for 3-wire or 4-wire load cell connections.
  • Environment: Ensure the installation environment falls within the specified temperature and humidity limits.

Usage Precautions:

  • Variant Identification: Do not interchange the “-65” variant with “-20” variants without verifying electrical compatibility.
  • Overload Protection: Install mechanical stops on load cells to prevent physical damage from excessive web tension.
  • Signal Integrity: Use isolated analog inputs on the receiving PLC or drive to prevent ground loop issues.
