Kettler treadmill - Kettler marathon ST – Service mode – Calibration procedure - Error codes – Error code troubleshooting

SERVICE MODE
When incline motor needs calibration:
1.When controller changed.
2.When incline motor is changed.
3.When both controller and incline motor are changed.
4.If controller CPU is changed.
CALIBRATION
1.To calibrate, make sure the treadmill is not running (running belt not moving).
2.Turn power on. Wait a few seconds.
3.Press the STOP and SPEED- buttons at the same time, then the buttons STOP and SPEED+, then the SPEED- button. The treadmill is in calibration mode.
Press the START button. The treadmill will run calibration for the incline motor.
NOTE: If error 5 appears, it means the controller remembers a different value, so we need to bypass the controller to calibrate the incline motor. In that case, we have to disconnect the incline sensor cable to bypass the old memory. Then calibration can be done properly.
4.Just run through a few functions to make sure everything is in good condition.
Er 01
Speed sensor
Speed sensor is broken.
Main power relay is broken(in the motor controller).
Motor is broken or motor wire is badly connected.
PWM circuit that is in console is broken.
Main cable is damaged.
Turn off and on the power.
Push Start key to test the treadmill.
Warning : Do not step on the treadmill, it is very dangerous.
1) Check if motor is running for short time.
if NO.
Check motor wire connection, motor brush connection, motor itself.
Motor controller circuit or signal cable was broken.
PWM circuit that is in console was broken.
if YES
Speed sensor wire connection , or speed sensor was broken.
Speed sensor circuit that is in motor controller was broken.
Signal cable or console was broken
Er 02
Over speed
When treadmill runs faster than target speed. - Check Power circuit.
When User kicks the treadmill belt faster intentionally.
Frequency is very low.
It usually happens during workout(14Km/h to 16Km/H).
Turn off and on the power.
Start the treadmill and check if there are Error 41 or others.
Warning : Do not step on the treadmill, it is very dangerous.
Er 06
Memory
EEPROM of console error, eeprom problem or circuit problem.
Frequency is very low.
Turn off and on again. If it happens continually , you have to change the console
Er 08
Angle switch
Angle switch broken.
When the treadmill is folded.
When Err 08 on the console, even if treadmill is not folded.
Check the cable connection first and then check the angle switch(motor control board).
Er 15
Under speed
When treadmill runs slower than target speed.
Motor is damaged.
AC input is lower than normal value(lower than 210VAC), with heavy user.
Deck and belt condition is not good.(Check silicone).
Turn off and on the power.
Push Start key to test the treadmill.
Warning : Do not step on the treadmill, it is very dangerous.
During testing, if motor makes electric howling noise.
Check the motor condition and motor wires are tightly connected.
Check the condition of deck and belt, if deck and belt are damaged
you have to change the deck and belt , and lubricate it with silicone.
Er 05 , Er 51 , Er 52 , Er 53
Elevation
Check incline sensor or motor.
Err 51,Err 52,Err 53 happen during self test or calibration.
Turn off and on the power.
Calibrate the elevation motor again and check the console value.
Push and hole 12%+ 6% keys together for 2seconds to calibrate the motor.
Then treadmill goes up and goes down to the bottom, please check the value on the it
It should be more than 190 at the top, and it should be less than 40 at the bottom.
Check the error message.
Er 51, Er 52, Er 53 or no message.
Check the elevation motor runs or not, when you test it ?
Warning : Do not step on the treadmill, it is very dangerous.
If no error message,
Please send the value that is displayed of the LCD during calibration to KETTLER.
You have to do calibration again, if you want to use the elevation function.
Er 40 , Er 41
Over acceleration
Treadmill accelerates too fast than normal.
It happens when the speed is less than 8 Km/H.
Fatal error. Stop using treadmill.
Power circuit could be broken.
Same as Er 40, but it happens at the beginning of workout.( During Start)
Turn off and on the power.
Start the treadmill and check the Error message again.
Check the motor runs or not , when you test it ?
Warning : Do not step on the treadmill, it is very dangerous.
