When the equipment is abnormal, sometimes the corresponding codes will be displayed in the middle of the lower part of the display, and each code has its own specific meaning. Therefore, you can analyze the causes and parts of the fault according to the information contained in different codes, and formulate corresponding treatment methods at the same time. Checking the fault code during machine maintenance is helpful to quickly repair the excavator fault. Entering excavator monitoring to check the fault code requires a password. Please check the relevant tutorials.
