1. Error Signal Check Steps And Sol tions
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.
1.1.1.Steps illustrate：

1
Show【LS】 on TIME window.
2
OFF the AC power source and wait 1 seconds
then ON the AC power.
3
Press START.
4
Do the running belt moved?
A：Moved then show【LS】：Execute step 5~8
B：Did not move then show【LS】：

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 para
meter on
CALORIES window when calibrate speed at
max speed 2 km/h(± .1).
In normal condition, the SPEED parameter
shall be between 34 ~35 .
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』
I
f still show error signal, have to check
the console wire, damage or connect
terminal problem.
I
f 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』

I
f 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 t
he 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
1 ~11.
1 I
f 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.
Refer to 2.2『Console Wire』
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. I
f loading
is too heavy the motor noise will more
louder over 12km/h and running belt speed
will decreased or slippery while loading
.
P
lease 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.

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 ERROR
ELEVATION ERRORELEVATION ERROR
ELEVATION ERROR PRESS STOP TO BYPASS
PRESS STOP TO BYPASSPRESS STOP TO BYPASS
PRESS 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.
