ONSOLE:

Interface that controls all functions of the Elliptical.

AIN CONTROLLER

The circuit board consist of the DC power supply for console、incline driver and tension motor driver, link the console to output appropriate voltages for tension motor that control the elliptical functions.

ENSION MOTOR

It can change to increase or decrease resistance level of brake.

NCLINE MOTOR:

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

ENERAL INFORMATION

ONSOLE

Contains Key controls and LCD Display.

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

ENSION MOTOR

Work voltage: DC 4.5~7.5V

Control resistance increases and decreases.

NCLINE MOTOR

This is a 120 volt AC motor.

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.

Operation

Window Display Mode

IDLE MODE

1.1 Each program profile will be displayed on the MESSAGE WINDOW sequentially.

1.2 Heart rate BAR will light up from the bottom and move up. Level, HR% Profile and Track loop will light up from bottom middle and move counterclockwise.

1.3 DATD WINDOE will display INCLINE= 10，LEVEL= 12，CAL = 681，TIME = 30：00，DISTANCE = 12.0，PACE =6：00，PULSE = 125. It will get into IDLE MODE without pressing any key after five minutes (not including IDEL MODE, DISPLAY MODE).

DISPLAY MODE

2.1 Pre-set: DISPLAY ON(DISABLE). You could set the DISPLAY ON/OFF by ENGINEERING MODE.

2.2 The console will not get into SLEEP MODE when the set up is “ON”, unless turn off the power. There is no RPM input in IDEL MODE, and enter to SLEEP MODE after thirty minutes without pressing any key.

2.3 Press the QUICK key to change SLEEP MODE. In IDLE MODE, hold and Press “ENTER”, “STOP”, “DISPLAY” key at the same time for more than two seconds to switch the SLEEP MODE ON/ OFF. Press “ENTER” key to confirm the set up and jump out to IDEL MODE.

2.4 In DISPLAY MODE, LCD screen will has no display, and backlit will be off. Press any key to wake up the system, and back into IDEL MODE.

2.5 Resistance in SLEEP MODE: Incline =1, FAN system OFF.

CHILD LOCK MODE

3.1 Pre-set: CHILD LOCK OFF (DISABLE). You could set the CHILD LOCK ON/OFF by ENGINEERING MODE.

3.2 The message window will display “CONSOLE LOCKED” twice, and then show the string “ CHILD LOCK-ON PRESS START AND ENTER TO ENABLE OPERATION ” by blinking when CHILD LOCK setup is ON. You could setup the CHILD LOCK MODE OFF by pressing “START” and ”ENTER” key for more then two seconds. After that it will enter to IDEL MODE.

3.3 All keys will be no action when CHILD LOCK MODE is active.

EXERCISE MODE（QUICK START）

4.1 In IDEL MODE, press START key enter to MANUAL MODE. The age, weight is presetting value. Time counting is count up from 00:00. All countable data will count up from “0”, and resistance is count up from “1”.

4.2 You could chose the program by pressing the key: MANUAL、PROGRAM、USER1、USER2、HRC1、HRC2. And then, press “START” key to start the workout. All parameter will be the preset value.
