• Enable signal
This is the signal generated by the inverter (pin CM2-L) for enabling the fan. When the treadmill
is halted it is at logic level low (0 Vdc), and immediately switches to logic level high (24.55
Vdc) when the "Start" button on the control panel is pressed.
This signal enters the fan interface board (pin 1-2 of connector CN1) and drives the relay on the
circuit board.
• VAC power supply
This is the mains power supply that enters the fan interface board (IN pin of connector CN2): it
must always be 220 VAC.
Depending on the state of the relay, this voltage is supplied to the fan (OUT pin of connector
CN2): it must be 0 when the motor is stopped, and 220 VAC when the motor is running.
