Universal control board working with potentiometer or keypad / manual tilt.

Control board adapted for use with potentiometer or keypad. Manual tilt.
The board does not have the tilt management part.
It works with a potentiometer, with added security features, such as:
- Motor line protection to increase safety in the event of a mosfet circuit;
- Input Signal Protection: If the potentiometer short-circuits, or the customer leaves the treadmill off at full power, the board will stop instead of going to full power;
- Protection on sudden commands: If the customer inadvertently turns the speed very quickly, the board will respond by increasing the speed gradually;
- Incoming AC line protection fuse.
