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：

Show【LS】 on TIME window.

OFF the AC power source and wait 1 seconds

then ON the AC power.

Press START.

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？

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』

f still show error signal, have to check

the console wire, damage or connect

terminal problem.

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』

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

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』

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

lease maintenance or replace the running

belt and running deck.

On the AC power and check the fan where on

the inverter operate normal, otherwise the

inverter will over heating and to start

protect.
