3.5 TROUBLESHOOTING - SPEED FEEDBACK INACCURATE
SPEED FEEDBACK INACCURATE
1) SYMPTOM:
a. The treadmill speed is higher or lower than the actual speed.
1) SOLUTION:
a. Enter Engineering Mode (See Section 4.1), and scroll to ENG 2 (Auto Calibrate). Press the key “ENTER” first
and then the key ”START” (Figure A & B). The treadmill running belt will begin to move automatically from speed
level P0 to P4.
P0—speed range around 0-1 KMPH P3—speed range around 10-15 KMPH
(Figure C)
P1—speed range around 1-5 KMPH P4—speed range around 15-20 KMPH
(Figure D)
P2—speed range around 5-10 KMPH
Upon successful calibration, the treadmill will beep several times. The console will automatically exit
Engineering Mode and return to the start-up screen.
b. If Auto Calibration can be completed successfully, normally this issue will be fixed.
If “E1” mistake is presented on the console during auto-calibration (Figure A), check the connection of the speed
sensor wire from the left frame (close to front roller pulley) to the MCB (Figure C). Replace the speed sensor wire
if needed.
If auto calibration can be still not performed, replace the MCB as the last step.
