ERROR CODES
Errors are divided in speed related errors (E1) , console memory related error (E2) , and elevation related errors (E3 /
E6). System should be properly calibrated (if possible) before attempting to troubleshoot error codes.
The following table contains standard error codes. Other error codes are enabled for development purposes but
cannot be remedied via engineering variables. Error codes can be remedied in some conditions by system calibration
or require toggle of system power to reset
MaintenanceLamp
Blue Light: Normal Opertation Mode: When the treadmills accumulated distace reaches the 5,000 mile mark
the Blue light will be displayed meaning the it is time for general maintenance to be performed. This light will
then come on at every 5,000 mile interval. To turn off the light after you have finished the maintenance hold
the incline ↓and the speed -at the same time for 3 seconds.
Red Light: Normal Operation Mode: This light will occure when there is a Error sent to the console display.
To fix this please see the Error Code guide number and follow the instruction on how to fix the problem.

E1 - Speed Feedback Error
OVERVIEW
If no belt movement is detected 10 seconds after pressing START the console calls a speed stall error (E1).
During normal run time operation the value stored during auto calibration is used to initially set the speed (e.g. target speed = 12
MPH, PWM ticks = Maximum PWM = 999). Once the speed is stabilized the actual speed is monitored and if different than the
target speed the PWM value is adjusted until the actual speed matches the target speed. If the PWM value is changed by more
than the amount of ticks required to change .8 MPH and the actual speed does not match the target speed then an (E1) error is
flagged. This error indicates the motor controller system is unable to maintain the target speed.

E2 – Console Memory Loss
OVERVIEW
If the console memory chip is damaged or has some sort of electrical spike the console memory could be lost. If so you will need to
replace the console board.

E3– Elevation Range / Elevation Stall
OVERVIEW
When elevation movement is commanded (e.g. elevation up) the elevation position feedback is expected to change in the correct
direction (e.g. increase in pot value for an elevation up command). If the elevation position feedback changes in the opposite of the
expected direction (e.g. elevation command up and elevation feedback decreases) a reverse elevation error (E3) is flagged.
To prevent the elevation from stalling at the lower travel end or running off on the top end of travel the elevation position feedback is
monitored. If the elevation position feedback is lower than expected (e.g. < 10) or higher than expected (e.g. > 250) then an (E3) is
called. To reduce the risk of elevation motor/system damage or overheating in the event of a stall elevation stall conditions are
monitored. If movement is commanded and the position feedback indicates no movement-taking place an elevation stall error is
called. This problem has been caused most frequently by overheated elevation motor.
