The hardware of fault diagnosis and alarm system is mainly composed of controller, display screen and other detection and protection control elements.
The system monitors the operation status of the excavator, and can give an alarm in time in case of abnormality, and point out the faulty parts. The system can automatically find faults, find fault components according to the measured fault parameters, and query the time of a fault and the name of the fault within a certain time. The application of the system can eliminate the hidden dangers of accidents as soon as possible, reduce the maintenance time, reduce the maintenance and maintenance cost, improve the operation environment and improve the operation efficiency.
The LCD interface panel is waterproof, dustproof, shockproof and has strong anti-interference ability. It can continuously monitor the operation of the machine and give an alarm according to the requirements. It adopts light control circuit, which can automatically turn on the backlight when the light is dark to illuminate the LCD screen. At different temperatures, the gray level of the LCD screen can be automatically adjusted to achieve the best visual effect. The device has the functions of total working hours and system time display, and can adjust the time. Flip the LCD screen to check the specific values of the collected parameters and whether the switching values are normal or not.
After working, only one working mode can be selected at a time. After a new working mode is selected, the original working mode is automatically eliminated. After restarting the excavator each time, the power mode returns to the standard mode, and the driving high and low speed selection switches are in the low speed state. Only when the switch is pressed can it be switched between high speed and low speed. After restarting the excavator every time, the automatic idle switch is in the effective mode of automatic idle. This function can be cancelled only by pressing the automatic idle switch.
