Instructions
1. Connect the power cord, ensure that the positive and negative switches are in the middle zero position, connect the DC power supply, ensure that the voltage range of the DC power supply is greater than 10V and less than 36V, and ensure that the output power of the power supply meets the working needs of the motor. Do not reverse the positive and negative terminals of the DC power supply, otherwise The governor may be damaged.
2. Connect the motor; the motor line can be positive or negative.
3. Adjust the switch, the forward and reverse switch is used to control the direction of the motor speed, when the switch is at zero, the motor stops.
4. Potentiometer knob, adjusting the potentiometer knob can change the output duty cycle of the governor, and the motor speed can be changed.
Use 0-10V external voltage control wiring instructions
The governor supports the use of an external DC voltage to control the speed, and the steps are as follows:
1. Remove the potentiometer (you can decide to remove it from the side of the circuit board or the side of the potentiometer according to your needs)
2. Connect the O-10V DC control signal to the middle pin of the potentiometer. 3. Connect the ground wire of the 0-10V DC control signal to the right pin of the potentiometer.
