When the device is abnormal, sometimes the corresponding code will be displayed in the middle of the lower part of the display, each code has its own specific meaning, thus, you can analyze the cause of the fault according to the information contained in the different codes And parts, at the same time work out corresponding treatment methods. Checking the fault code during machine maintenance is helpful to quickly repair the excavator fault. Entering the excavator monitoring to view the fault code requires a password, please refer to the relevant tutorial.
