Working Principle

Common Faults and Solutions

• Communication Failure: May be caused by poor communication cable connection, incorrect communication parameter settings, or damaged communication interfaces. Check if the cables are properly connected, confirm whether communication parameters such as baud rate and address are correct, and contact professionals for maintenance or module replacement if the interfaces are damaged.

• Inaccurate Measurement: If there is a large deviation in measuring physical quantities such as temperature and pressure, it may be due to sensor failure, abnormal input signals, or incorrect module calibration parameters. Check whether the sensor is working normally, verify that the input signals are within the module's specified range, and re-calibrate the module if necessary. If the gas detection is inaccurate, it may be due to aging or contamination of the catalytic combustion sensor, and consider replacing the sensor or performing cleaning maintenance.

• Abnormal Output: May be caused by damaged output interfaces, abnormal loads, or internal program errors of the module. Check if the load is normal, try replacing the device connected to the output interface. If the problem remains unsolved, re-download the correct program into the module. If the interface is determined to be damaged, repair or replace the module.

• Module Overheating: May be caused by poor ventilation in the installation environment or long-term high-load operation of the module. Ensure that there is sufficient heat dissipation space around the module, clean up the surrounding dust, avoid long-term use in high-temperature environments, and suspend use if necessary until the module cools down before restarting.
