It is common to see this error as and L5 error, but it is actually an LS error. The following information will define this error and give you the possible solutions to fix this issue.

LS Error with No Belt Movement on Landice Series Treadmills

LS Error on Landice L-Series Treadmills with No Belt Movement Probable Cause A LS error on the Landice L-Series treadmills can also look like L5 and this error code means there is a loss of speed signal. If this error occurs with no belt movement, the causes for the LS or L5 error are:A) Faulty upper display board or faulty relay board
B) Improper speed control wiring
C) Improper motor control wiring
D) Worn or faulty motor brushes
E) Faulty pwm/relay combo board or faulty drive motor
Corrective Action A) Enter Open Loop Speed mode and set treadmill speed to confirm proper line voltage to pwm board and that the green BELTSW light is lit on the relay board. Replace upper display board or relay board if necessary.
B) Inspect speed control wiring and correct wiring if necessary:

1. Checking purple wire from V+ on pwm board to P3 on the relay board
2. Checking orange wire from P1 on pwm board to P1 on the relay board
3. Checking brown wire from P2 on pwm board to P2 on the relay board
4. Confirm P3 on pmw board has no connection

C) Inspect motor control wiring, checking wires from motor to A+ and A-. Correct wiring if necessary.
D) Inspect motor brushes verifying brushes slide freely, are at least 3/8" long, are curved and have no burns or cracks. Also check the brush springs and verify that the brush copper wire is not burned or broken. Replace both motor brushes if necessary.
E) Inspect motor turns and is not seized up or has a broken shaft. Replace motor if necessary. Also verify at least 90VDC present from the black (A+) wire and white (A-) wire from the pwm board to the drive motor. If voltage is present, replace pwm/relay combo board. If no voltage present, replace drive motor.
Details about LS Error on Landice Series Treadmills with Belt Movement
LS Error on Landice L-Series Treadmills with Belt Movement Probable Cause A LS error on the Landice L-Series treadmills can also look like L5 and this error code means there is a loss of speed signal. This error can occur with belt movement but speed will not increase. Causes for the LS or L5 error with belt movement are:A) Speed sensor is out of adjustment
B) Speed sensor is damaged or faulty
C) Display cable is damaged or faulty
D) Improper speed control wiring Corrective Action A) Speed sensor should sit parallel with the flywheel and gap between speed sensor and flywheel should be within 1/16". Adjust speed sensor if necessary.
B) Inspect speed sensor connector to relay board. Check for pushed pins or loose wires. Repair or replace speed sensor assembly if necessary.
C) Inspect upper harness or display cable connector to relay board. Check for pushed pins or loose wires, giving specific attention to pin 5 (brown) and pin 9 (green). Repair or replace display cable if necessary.
D) Inspect speed control wiring:

1. Checking purple wire from V+ on pwm board to P3 on the relay board
2. Checking orange wire from P1 on pwm board to P1 on the relay board
3. Checking brown wire from P2 on pwm board to P2 on the relay board
4. Confirm P3 on pmw board has no connection

Correct speed control wiring if necessary.

The blue wire from the Ac goes to the y2 on the board for the furnace the yellow and brown goes to c on the board for the furnace and the last wire goes to y1 on the board for the furnace

antenna wire connection on the circuit is cut and I do not know where the weld

antenna wire connection on the circuit is cut and I do not know where the weld

you might need to solder it
You attach wires to printed circuit boards (PCB) in a process called soldering. You heat the wire and PCB pad, melting the solder wire and allowing it to flow onto the wire and pad. The solder wire used is typically a lead-tin alloy although in some special cases, silver is used. Soldering a wire to a printed circuit board may be part of making, repairing or modifying the board or connecting it to another device.

Clean the pad on the circuit board where the wire will be attached. Gently rub the eraser on the pad until it is clean and shiny. Strip about 1/4 inch of insulation from the wire. Tin the end of the soldering iron by melting a small amount of solder onto the iron tip. Heat the wire end with the soldering iron for a few seconds and briefly touch the solder wire to the bare wire, just long enough to melt the solder, and let it flow into the stranded wires. This is called tinning the wire. Tinning the wire is not necessary with solid or single strand wire. Insert the wire end through the hole in the circuit board pad from the top or component side of the board. Bend the end of the wire slightly to prevent the wire from falling out while soldering but do not let the wire end touch any other component lead or another pad on the circuit board. Apply the soldering iron tip to the wire end and solder pad at the same for a few seconds until the solder used to tin the wire end melts. Apply just enough new solder to make a dome-shaped puddle on the pad that covers the hole and the wire. Remove the iron from the pad but do not move the board for a minute. Cool the new soldered joint and do not move the board until the solder hardens. Clip the wire end off with the wire cutters. The wire is permanently attached to the printed circuit board.

Communication problem. Check the wiring between the Main
Control Board and the Speed Control Board. Wiring bad, correct wiring problem. Wiring good, replace the Main Control Board. If the problem is not corrected, replace the Speed Control Board.

please remember the wires before. wires again the old board, and make a wiring diagram. After you did , you must try again with the new board, and repeat the process, very Important.
If the problem persist, call to the supplier board, and tell them if the can send some wiring diagram, or see if with the new board there are some schematic wiring diagram. Otherwise, you must make some errors and additional problem you will find it.Contact them inmediately.
God bless you

Hello there,


Below is an image of *********** Board with number indication and wiring explanation. From your manual page 1-6 you can see the image below and 1-7 for the connector, jumpers, slots. as indicated in your problem I will only answer problems related to the wirings.

• For the Front Panel

1. There are 8 wires from the front panel's casing, excluding USB connectors and front audio cable.

2. Just plug the front panel switch headers to the F_Panel main board connectors. 1 & 2 are positive, if the led do not light change polarity but Im sure it will.

Note:The mainboard provides a front panel connector for electrical connection to the front panel switches and LEDs. JFP1 is compliant with Intel® Front Panel I/O Connectivity Design Guide.

• For the USB connectors

1. If your casing has a USB header on the front bezel you can put it on any connector. You can also purchase a USB module cable or an internal card reader and plug the headers to any of those connectors.


Note: Observe Polarity, do this Vcc, -Data, +Data, Gnd ,(NC) ground is always near to NC.

Plug it at your own risk, reference image are already shown.

• Front Panel Audio connectors

1. Look for FP_Audio header from your casing and plug it to the connector.

*Asus recommend you connect a high definition front panel audio module to this connector to avail of the motherboard's high-definition audio capability.



Hopefully this information helps.


Thank you for using FixYa.

Upper display lights up;treadbelt moves;speed will not increase;L5 error.

Check speed sensor alignment.
It should be within 1/16" of the flywheel
and parallel to the flywheel.
Is it out of position?
Unplug 3 wire speed sensor connector from
relay board. Check for pushed pins or loose
wires.
Any found?
Unplug 12 wire upper harness connector
from relay board. Check for pushed pins or
loose wires. Specifically look at 8 (White)
and 12 (Green).
Any found?
Is speed control wiring OK?
Purple wire from V+ on pwm board to P3 on relay board.
Orange wire from P1 on pwm board to P1 on relay board.
Brown wire from P2 on pwm board to P2 on relay board.
P3 on pwm board has no connection.
Adjust speed sensor:
1.Use 1/2" wrench and loosen
the two lock nuts securing
sensor to it's bracket.
2. Adjust sensor gap to 1/16".
3. Tighten lock nuts.
Repair or replace speed
sensor / harness assembly.
