Description


The excavator computer board (scientific name main controller) is called the "brain" that controls the machine and plays a vital role in the normal operation of the excavator. The computer board is like our human brain, which will collect various sensors The information is compared, calculated, processed and output, and the engine speed is controlled to coordinate and match the action of the hydraulic system. Each excavator has a computer board, but the installation place is also different.

 


Characteristic
 
1. The throttle computer board of the excavator brand that uses the DC motor can be replaced.
2. External power supply, 2 pressure switches, accelerator knob potentiometer, accelerator motor and speed sensor are required. According to the wiring as above, it can have the electronic throttle function.
3. The throttle knob can be used to increase or decrease the throttle. After turning on the automatic idle speed switch, if the rotation speed is above about 1200 rpm, the automatic idle speed adjustment will be performed after 5 seconds. When any condition of the pressure switch, automatic idle speed switch and throttle knob changes, the automatic idle speed will be exited. to the RPM position set by the throttle knob.
4. Different engines have different flywheel teeth, so there will be differences in the detection of the speed signal.
5. The pressure switch is normally open type. That is, when the pressure switch is turned off, it is a necessary condition for automatic idle speed. When the pressure switch is turned on, it will exit the automatic idle speed when it is grounded.
6. The speed sensor connection only needs to be connected in parallel, that is, there is no need to disconnect the original car line, just peel off the original car speed sensor wiring harness, and connect two wires in parallel.
