a) Safetykey:
b) Magnetic key fits in the Console to activate all functions.
c) Console:
Interface that controls all functions of the treadmill.
d) Main controller:
A circuit board that incorporates the DC power supply and
takes input from the console and sends out appropriate
voltages that control the treadmill functions.
e) Treadmill motor:
A variable speed, reversing 0 - 90 volt D.C. motor that
powers the main running belt.
f) Incline motor:
A variable elevation, Reversing 110 volt AC motor that sets
the incline of the treadmill.

B GENERAL INFORMATION
1. CONSOLE
a) Contains 6 windows which are twenty rows of RED-color
“dots” indicate each segment of a workout.
2. MAIN CONTROLLER
a) Contains power supply and control circuits.
3. TREADMILL MOTOR
a) Variable speed reversing 0-90 volt DC motor.
b) Has three wires red, black and green.
If there is DC voltage on the Red wire (M+) the treadmill
motor will turn clockwise.
If there is DC voltage on the Black wire (M-) the treadmill
motor will turn counter-clockwise
The higher the voltage the faster the motor turns.
The green wire is ground.
