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.
