Frequently Asked Questions (FAQ)

1. Q: What is the recommended cable type for connecting strain gauge sensors to the PFEA112-65?

   A: Shielded twisted pair cables with low capacitance are recommended to minimize signal noise and ensure measurement accuracy, especially over longer distances.

2. Q: Can the PFEA112-65 handle unbalanced or noisy strain gauge signals from old sensors?

   A: Yes, the module includes differential input and internal filtering mechanisms designed to reject common-mode noise, improving performance even in suboptimal sensor conditions.

3. Q: Is it possible to switch between the two input channels without power cycling the module?

   A: Yes, switching between channels is supported via configuration software through the RS-232 or RS-485 interface. No need to restart the module.

4. Q: What are the LED indicators on the front panel used for?

   A: The front-facing LEDs provide quick diagnostics for power status, sensor fault, signal error, and operational readiness, which helps during commissioning and maintenance.

5. Q: How can I verify if the sensor supply voltage (5V DC) is functioning correctly?

   A: Using a multimeter, measure across the sensor supply terminals. A deviation from 5V indicates either an internal fault or external overload.

6. Q: What is the maximum load impedance for the analog output signal?

   A: The analog output can drive loads with an impedance of at least 10 kΩ. Lower impedance loads may cause signal distortion or voltage drop.

7. Q: Can two PFEA112-65 modules be used together in a master-slave tension monitoring configuration?

   A: While each module operates independently, you can synchronize output data via the PLC or controller receiving analog inputs, provided your system supports it.

8. Q: How is zero-load calibration performed on this module?

   A: Calibration is typically done via the configuration software or DIP switches. Zero calibration involves applying no load to the sensor and setting the baseline reading to zero volts or equivalent.

9. Q: What happens if a sensor becomes disconnected during operation?

   A: The module will detect the sensor fault, activate the corresponding LED warning, and optionally drive the output to a failsafe state depending on configuration.

10. Q: Does the PFEA112-65 support sensor redundancy in case one input fails?

    A: It supports dual input channels, which can be configured for redundancy or independent monitoring. In redundancy mode, the second channel can act as a backup for continuity of tension control.
