L5 code after ten seconds from start up

Hi there!

L5 sometimes may refer to LS(Low Speed). There might be a problem with your motor sensor. It is best to call the place where you purchased this device for possible replacement if a reboot will not suffice.

Hi There, L5 error should refer to the "LS" error which looks up to a speed problem. When you start the machine up, it boots fine and then when you press start or go is says err ls ? If the walking belt doesn't move at all when you try to start it, listen for a "Click" on that lower board when start is pressed..... If the walking belt moves for a second and then stops and the console says err ls, then you may have a speed sensor problem. These control boards are repaired by Jatinah Electronics who can be found with a google search. Good Luck!

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.

This may be a faulty speed sensor.
Or a faulty LCB

follow this steps and fix it. God bless you
SAFETY SHUTDOWN Loss of Speed Signal" or "L5" WITH belt movement
This is usually an indication of a speed control malfunction. The upper board is not recognizing a signal pickup from the speed sensor. This could be due to the speed sensor being misaligned, improper connection, or bad speed sensor. Refer to the flowchart on page
"SAFETY SHUTDOWN Loss of Speed Signal" or "L5" WITH NO belt movement
The speed sensor is not recognizing any motor movement. This displays the error message to the upper board.
NOTE: USE THIS FOR DIAGNOSING THE PWM/RELAY COMBO BOARD

Yeah - the sensor is the problem... It is magnetic... You can find it next to the wheel on the belt - It is fairly small.... There is a metal disc in the wheell on the belt that is a magnet.. As it passes by the sensor - the sensor registers the magnet and can simply calculate speed based on the frequency of the passes... Sometimes the sensor slides too far back and ergo can`t register the magnet passing by - Then you get the L5 error...

hi,
LS mean low speed error, Please check the sensor wire( if moor move). if not move please check control board.
