LECTRICAL CONFIGURATION
Note: Electrical servicing of this treadmill is limited to board
level replacement.
1. CT80-NT04 TREADMILL COMPONENTS
a) Safety key:
To fits on the Console that activate all functions. If no safety
key, console can not be controlled.
b) Console:
Interface that controls all functions of the treadmill.
c) Main controller:
The circuit board consist of the DC power supply for
console、incline driver and DC motor driver, link the
console to output appropriate voltages for motor that
control the treadmill functions.
d) Treadmill motor:
This is a variable speed for DC motor. To control the 0 –90
voltages on the main controller, it can to increase or
decrease speed of running belt.
e) Incline motor:
This is an ac motor. User can to control variable
elevation by console within main controller.

f) Contains touch controls and LCD Display.
2. MAIN CONTROLLER
a) Include power supply 、 motor driver control circuit and
incline control circuit.
3. TREADMILL MOTOR
a) It’s a variable speed on 0-90 volt DC motor.
b) Have three wires red, black and green.
c) If there is DC voltage on the Red wire (M+) the treadmill
motor will turn clockwise.
d) If there is DC voltage on the Black wire (M-) the treadmill
motor will turn counter-clockwise.
e) The higher the voltage the faster the motor turns.
f) The green wire is ground.
4. INCLINE MOTOR
a) This is a 120 volt AC motor.
b) Have four wires, red, black, white and green.
c) Has one 3 pins cable of position sensor.
d) If there is AC voltage on the Red wire (UP) the incline motor
will increase the incline.
e) If there is AC voltage on the Black wire (DOWN) the
incline motor will decrease the incline.
f) The White wire (COM) is neutral.
