Working Principle:
When a strip passes over the measurement roll, tension creates force vectors detected by the piezomagnetic load cells. The PFEA113-65 receives these raw signals, applies the configured Wrap Gain based on the geometric wrap angle, and subtracts the mechanical tare weight. The resulting absolute tension is scaled to the selected engineering units and transmitted to the automation system, which adjusts motor torque to maintain the desired setpoint.
Installation Requirements:
- Load Cell Verification: Cross-reference the load cell nameplate Nominal Load with the PFEA113-65 configuration before commissioning.
- Wrap Angle Calculation: Accurately measure and input the wrap angle to calculate the correct Wrap Gain; incorrect angles will result in false tension readings.
- Network Termination: Ensure proper Profibus termination resistors are in place at both ends of the network segment.
- Pre-Thread Zeroing: Execute the SetZero routine immediately prior to threading the strip to account for any residual mechanical forces.
Usage Precautions:
- Range Scaling: If the process tension is significantly lower than the unit’s maximum capacity, reduce the configured measurement range to maximize resolution and control accuracy.
- Sensor Protection: Avoid striking or overloading the load cells during mechanical maintenance, as piezomagnetic elements are sensitive to extreme shock.
- Backup Configuration: Regularly export the parameter set via PC to prevent loss of critical calibration data during unexpected hardware failures.
