Test Mode
To enter Test Mode press and hold down any key on the display while turning the power switch to the on (I) position. When all keys are released “PRO” and the software revision “rx.x” are shown on the display. To exit Test Mode press Stop.
Error Description
bAd2 > Internal RAM error.
bAd3 > Watchdog timeout.
Err1 > Belt didn't start (or no speed sense).
Err2 > Underspeed (2 mph for 2 seconds without correction in process).
Err3 > Speed sense lost.
Err5 > No 0 switch sense within timed limits. This is declared when the timed elevation reaches -2% without tripping the index.
Err6 > Overspeed (1 mph for 1 second or 2 mph for 0.2 seconds without correction).
Err7 > EEPROM error (memory lost, loads new defaults, enters Test Mode).
Err9 > Brush wear too low. Indicator has been activated for over 100 miles.
ErrE > 0% always on (or switch disconnected or wired backwards). This means that timed elevation has gone up 2% and the index is still sensed.
Motor Current and Voltage
Tools Required
# Phillips screwdriver
# Voltage meter
Measure current draw.
A. Enter Test Mode by holding down any key on the display while turning the power switch to the on (I) position.
B. Quick Press the Start key. The belt will move at 1 mph (1.0 kph).
C. Without standing on the belt, bring the speed of the treadmill up to 3 mph (4.8 kph), Press the
METs key and take note of the load value in the top center display.
D. Have a second person walk on the belt at 3 mph (4.8 kph) and take note of the load value in the top center display and the weight of the person.
E. Stop Press to exit Test Mode.
2. Disconnect the external power source.
A. Turn the main power switch on the left side to the off (O) position.
B. Unplug the treadmill from the power outlet.
3. Remove the motor cover.
A. Using a Phillips screwdriver, loosen three screws on each motor cover side (left and right).
B. Lift the motor cover center up and off the treadmill. The screws will stay in place.
4. Check the belt and deck condition.
5. Check the motor voltage.
A. Plug the treadmill back in and turn it to the on (I) position.
B. Enter Test Mode.
C. Without standing on the belt, Bring the speed of the treadmill up to maximum speed, 12.4 mph (20 kph).
D. Using a voltage meter, contact the meter’s red lead to the connector of the motor’s red lead and the meter’s black lead to the motor’s black lead on the lower board.
E. Note the reading on the voltage meter then carefully remove both leads.
F. Exit Test Mode by pressing Stop.
6. Attach the motor cover.
A. Lower the motor cover center into position.
B. Using a Phillips screwdriver, tighten the three screws on each side.
Speed Sensor Adjustment
Tools Required
# Phillips screwdriver
# 1/4” Socket wrench
3 7/16” Open end wrench
1. Disconnect the external power source.
A. Turn the main power switch on the left side to the off (O) position.
B. Unplug the treadmill from the power outlet.
2. Remove the motor cover.
A. Using a Phillips screwdriver, loosen three screws on each motor cover side (left and right).
B. Lift the motor cover center up and off the treadmill.
NOTE: The screws will stay in place.
3. Visually inspect the drive motor fan.
A. Turn the flywheel slowly and look for dirt or damage to the drive motor fan.
NOTE: If the drive motor fan or speed sensor is dusty use a soft dry cloth to wipe off the dust.
A. Using a 1/4” Socket wrench, tighten the mounting screw that attaches the drive motor fan to the drive motor shaft.
4. Visually inspect the speed sensor.
A. Inspect the speed sensor and look for dirt or damage to the speed sensor or speed sensor mounting bracket.
NOTE: If the speed sensor is dusty use a soft dry cloth to wipe off the dust.
B. Using a 7/16” Open end wrench, tighten the mounting nut that attaches the speed sensor bracket to the drive motor.
C. Ensure that the gap between the speed sensor and drive motor fan is even on both sides.
5. Test for speed errors.
A. Connect the power cord to a power outlet.
B. Enter Test Mode.
C. Bring the speed of the treadmill up to maximum speed, 12.4 mph (20 kph).
D. After reaching maximum speed take note of the actual speed that is displayed in the lower left window. If it fluctuates in over 0.5 mph increments then your speed sensor gap needs to be inspected.
E. Slowly adjust the speed down to 1.0 MPH (1.0 KPH).
F. Stop Press and turn the power switch to the off (O) position.
G. Enter Test Mode again and check the error log for Error 3. If Error 3 occurred readjust the speed sensor and test again.
H. Exit Test Mode by pressing Stop.
6. Attach the motor cover.
A. Lower the motor cover center into position.
