1. Display emits the incline signal, which travels from the ribbon cable to the drive board.
2. The transformer breaks wall power down into smaller voltages for various circuit operation, including the incline motor.
3. The drive board puts out power for the motor. Up operation: K4 relay clicks, LED 4 lights. Down operation: K2 relay clicks, LED 3 lights.
4. The incline motor operates according to power from the drive board. UP operation: K4 relay clicks, LED 4 lights. Down operation:
K2 relay clicks, LED 3 lights.
5. As the incline motor moves, the variable resistor (VR) moves, changing VR output voltage. The VR voltage travels to the drive
board, up the ribbon cable, to the display.
6. The display program IC uses the VR signal to determine the position of the incline. This is used to determine whether to supply or
cut off power for incline motor operation.
