decrease speed of running belt.

NCLINE MOTOR:

This is an ac motor. User can to control variable elevation by console within main controller.

ENERAL INFORMATION

ONSOLE

Contains buttons control and LCD Display.

Main controller Include power supply 、 motor driver control circuit and incline control circuit.

SSeerrvviiccee MMaannuuaal

READMILL MOTOR

It’s a variable speed on 0-90 volt DC motor.(for 120V model) or 0-180 volt DC motor (for 220V model)

Have three wires red, black and green.

If there is DC voltage on the Red (white) 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.

NCLINE MOTOR

This is a 110 volt AC motor for 110V model (220 volt AC motor for 220V model)

Have four wires, red, black, white and green.

Has one 3 pins cable of position sensor.

If there is AC voltage on the Red wire (UP) the incline motor will increase the incline.

If there is AC voltage on the Black wire (DOWN) the incline motor will decrease the incline.

The White wire (COM) is neutral.

The green wire is ground.
