This is the digital display tube circuit board with fixed time controlling function. There are 12VDC power input and output terminals, manual switch, digital tube for time and jumper.
There are also several buttons and terminals at circuit board. S1 (SET), S2 (+), S3(-), S4(LEARNING BUTTON) from right to left.
There are 3 controlling methods in it. They are manual switch control function, remote control function and fixed time controlling function. First of all, we will introduce the code learning and manual switch control function.
Code Learning:
1) Press button S4; signal LED on the controller keeps shining. The controller enters into status of LEARNING.
2) Press any one button on remote control. If signal LED flashes quickly 5 times and turns off, it means learning is successful.
3) When controller is in the status of LEARNING, press again button S4, signal LED turns off, learning process will be discontinued.
4) The controller can learn several remote controls with different codes.
We can test the learning situation, press “▲”, motor rotates in positive direction. Press “■”, stop the motor.
Code Deleting:
If you don’t want the controller to work with the remote control when you have learned remote control to the controller, you can delete all codes of remote controls, which are stored in the controller.
Operation: Press and hold S4 until signal LED flashes slowly; release the button, LED keeps slow flash. We can test the code deleting situation, press any buttons of transmitter, there is no response from motor. That means all stored codes have been deleted successfully.
Here is code learning and deleting videos for your reference.
