1. Error Signal Check Steps And Solutions 1.1. 【LS】：Can not receive signal from speed sensor over 8 seconds while workout, all

windows display will off, all output will stop, and show 【LS】 on TIME window.

※If this is a all new product that just finished assemble, there are more possibly in

assemble problems, maybe connect wire not well or wire damaged while assemble.

5

Press STOP then press START and FAST

simultaneously immediately, to leave you

hand from keys till dot-matrix window show

WELCOME.

6

LED display windows will do the scan mode

after show WELCOME.

After scan mode, to press ENTER till

incline window show 『15』 then press START

to begin calibrate mode.




Do it can be calibrate normally or show LS

on TIME window？

7

If calibrate normally and return to idle

mode, please check the SPEED parameter on

CALORIES window when calibrate speed at

max speed 20km/h(±0.1).

In normal condition, the SPEED parameter

shall be between 340~350.

If calibrate abnormal, open motor cover

and check speed sensor connected well.

If speed sensor connected well, please

replace the sensor and check again.

Refer to 2.3『Speed Sensor』

If still show error signal, have to check

the console wire, damage or connect

terminal problem.

If console wire check ok, please replace

the console wire then back to execute step

2, check the error signal disappear or not.

Refer to 2.2『Console Wire』

8

If still show error signal after replace

the console wire, please replace the

console PCB then back to execute step 2,

check the error signal disappear or not.

Calibrate abnormal, show 【LS】

Calibrate normal, return to idle mode




9 Open the motor cover then ON the AC power,

press START to begin and check the pilot

lamp on interface PCB.

1. Is the LED7 light up before show 【LS】？

2. Is the LED6 flash before show 【LS】？

LED7 or LED6 not light or flash：Execute

step 12~13.

LED7 light up and LED6 flash：Execute step

10~11.

10 If LED6 & LED7 normal, have to check the

inverter first, if inverter check normal,

please replace the interface PCB then back

to execute step 2.

Refer to 2.4『Inverter』

11 Check the console wire, damage or connect

terminal problem.

After check or reconnect or replace the

wire, back to execute step 2.


12 After check or reconnect or replace the

wire but still show error signal, please

replace the console PCB then back to

execute step 2.

13 If all function are normal and no error

signal after reset power, it maybe cause

by power core, maybe power core connect not

well, please check the power core.

If all function are normal and no error

signal after reset power, maybe the

loading is too heavy and inverter to start

the over current protect mode. If loading

is too heavy the motor noise will more

louder over 12km/h and running belt speed

will decreased or slippery while loading.

Please maintenance or replace the running

belt and running deck.

14

On the AC power and check the fan where on

the inverter operate normal, otherwise the

inverter will over heating and to start

protect.

Refer to 2.4『Inverter』



1.2. 【E1】：When memory device damaged or read or write had program, all window display

will be off and all output will be stop and show【E1】on TIME window, show【EEPROM

ERROR】 on dot-matrix window.

1.2.1.Solution：Replace the console PCB.

1.3. 【E2】：IF incline had some problems when initial, incline can not reach the right

position, will show 『ELEVATION ERRORELEVATION ERRORELEVATION ERRORELEVATION ERROR PRESS STOP TO BYPASSPRESS STOP TO BYPASSPRESS STOP TO BYPASSPRESS STOP TO BYPASS』on dot-matrix window,

press STOP to bypass the signal but incline function can not be use, if incline had

some problems when during workout, the INCLINE window will show 【E2】but other

function are normal to use.

※If this is a all new product that just finished assemble, there are more possibly in

assemble problems, maybe connect wire not well or wire damaged while assemble.

1.3.1.Steps illustrate：

magnet close to the speed sensor, then

measure the wire PINs by multi-meter.

It shall be have low resistance in the

normal condition.(short condition)

3 To turn around the front roller till the

magnet leave away from the speed sensor,

then measure the wire PINs by multi-meter.

It shall be have infinity resistance in the

normal condition.(open condition)



2.4. Inverter check：


1 Switch ON the AC power and to check the fan

where on the inverter.

It shall be operate when power ON and stop

when power OFF.

2 To execute the 2.1.3.2 step 1 & 2, it shall

be operate normally.

2.5. Incline motor check：


1 Switch OFF the AC power, to pull out the

incline motor power wires.

(red/white/black wire)

terminal and connect the incline motor

wires white one and red one to inverter

power source terminal.

Switch ON the AC power, the incline motor

shall be operate in the normal condition.




3 To continue, switch OFF the AC power, to

connect the incline motor wires white one

and black one to inverter power source

terminal.

Switch ON the AC power, the incline motor

shall be operate in the normal condition.

resistance(white and black wire connect

terminals), the resistance shall be change

between range 0~10kΩ when turning the VR.

The lowest incline position resistance

about 0.83kΩ, the highest incline

position about 6.72 kΩ

If you want to replace the incline motor

or VR, you have to connect the new incline

motor all wires to interface PCB and switch

ON the power for correction before fix on

the treadmill. Or to adjust the resistance

of VR to the lowest position value.

Otherwise, it will be jam or break away.

12km/h(or higher speed) and wait it to

stable. Decrease speed by press quick

speed key 10.

2 Check the pilot lamp LED3 where on the

interface PCB after press quick speed key.

Do the LED3 flash after press the quick

speed?

Refer to：


3 If LED3 flash after press quick speed key

to decrease speed, the speed command

signal is no problem, console wire no

problem, maybe the interface PCB or

inverter got some problems, please check.

Refer to：


2.4『Inverter』

4 If LED3 did not flash after press quick
