Adjustments of the speed control potentiometer will change resistance at terminals P1 and P2 varying the DC voltage to the motor. The speed of the conveyor motor will increase or decrease as the DC voltage from the board increases or decreases respectively. NOTE: The conveyor control uses a sensor and magnet, mounted on the conveyor motor that senses motor speed.
