3.3.4. THE SIGNALS INVOLVED
The machine controls the incline through the CPU board and the driver board, as illustrated in the
figure below:
The control logic involves the following signals:
• Up Signal
This is the signal generated by the CPU board (pin 5-12 on connector K4) to enable movement
of the up-down motor in the “up” direction. In normal conditions the signal is at logic level low
(0 Vdc), and it goes high (4.65 Vdc) to actuate the motor. The signal remains high for the entire
duration of the movement.
The signal enters the driver board (pin 5-12 of connector J6) and enables the movement of the
motor in the desired direction.
