DESCRIPTION
A E LECTRICAL C ONFIGURATION
Note: Electrical servicing of this treadmill is limited to board
level replacement.
1. XT90-NT23 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
consol e、 incline drive r 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.
