SPEED CALIBRATION: L-SERIES PWM TREADMILLS

1. Enter the O.L.S. Mode (Open Loop Speed) by pressing "MENU" and "START" simultaneously
for Executive Trainers and "FAST" and "START" for all other models.
2. Adjust the max speed first. Bring the set speed to 12mph. Let actual speed stabilize.
3. Adjust the MAX potentiometer on the PWM motor control board accordingly. (See Picture on
page 43)
CW = increase speed / CCW = decrease speed.
The actual speed will be displayed in the center display window.
4. Decrease set speed to 2.0mph. Let actual speed stabilize. Adjust the MIN pot
accordingly. (1.9 to 2.1mph is acceptable)
5. Before turning treadmill off, check the MAX speed one more time for accuracy. If speed
calibration does not fix problem suspect relay board failure.
