Installation and Wiring Steps

Correct installation is the foundation for ensuring the long-term stable operation of the 8Q3B. Please follow these steps:

  1. Confirm the power supply is 24V DC and turn off the power switch.
  2. Fix the 8Q3B on a bracket with low vibration, avoiding direct sunlight.
  3. Connect the power and signal wires according to the wiring diagram in the manual, paying attention to polarity.
  4. After checking that the wiring is correct, turn on the power and observe the indicator light status.

Calibration and Debugging Methods

The 8Q3B is calibrated at the factory, but regular calibration is recommended after long-term use. Calibration requires a standard signal source and a multimeter.

  • Zero Calibration: Input a 4mA signal and adjust the zero potentiometer so that the output is 4mA.
  • Full-Scale Calibration: Input a 20mA signal and adjust the span potentiometer so that the output is 20mA.
  • After calibration is complete, record and archive the calibration data.

Common Faults and Maintenance

The 8Q3B has a self-diagnostic function. Common faults can be troubleshooted through the fault code table in the manual. Daily maintenance should note:

  • Regularly check whether the wiring terminals are loose.
  • Use a damp cloth to clean the housing, avoiding corrosive solvents.
  • Perform an accuracy check every 12 months.
