From the process of control conveyor system , the first step Research to control the conveyor belt in the conveyor system, then the next step is to design the circuit control cabinet, CCP and HSD control cabinet.With equipment in the control system and control cabinet production according to the designed format, when the design is finished. Install the control cabinet Caleb the circuit with the sensor. In-system equipment when the control circuit is finished, the trial is conducted by a trial operation through a CCP's system and the operation of the HSD cabinet with the sensor. The open-close position of the bead is positioned according to the desired position and test the direction of rotation of the motor and the communication status of the baggage from the scanner according to the system requirements. By the conclusion of the electrical circuit in conveyor control systems, it can be used as well as designed and efficient
