Troubleshooting: Treadmills
E4: Solution
1. Check power to the treadmill, as insufficient voltage to the treadmill can cause this error to reoccur. Check the power
socket that the tread is plugged into. Eliminate any extension cords or surge protectors (plug the tread directly into
a functional power source). Make sure the circuit is not overloaded. Make sure the circuit is NON-GFI.
2. Calibrate (See engineering mode for specific treadmill).
3. If calibrations do not hold, replace upper console.
Note: Usually simultaneous with an E6.
E5: Solution
1. Check large data cable connections at the lower and upper boards
2. Check the elevation plug connection at the lower board.
3. Calibrate (See engineering mode for specific treadmill).
a) If dashes appear and it says DGA3 in profile reboot treadmill.
Reboot treadmill
Or:
b) If console enters engineering check the calibrations of P4 and P5.
4. Test/change large data cable (use large data cable information provided in the data cable portion of this Guide)
5. Replace lower board
6. Replace elevation motor
E6: Solution
1. Check the elevation plug connection at the lower board.
2. Check ALL large data cable connection at the lower and upper boards.
3. Calibrate (See engineering mode for specific treadmill)
4. Test/change large data cable (use large data cable information provided in the data cable portion of this Guide).
5. Replace elevation motor
E7/E9: Solution
1. Certain lower boards have an LED that flashes when the magnet on the roller passes the sensor. Adjust sensor
position if LED does not flash. See lower board basic troubleshooting for lower boards with the LED.
2. Unplug RPM sensor at the lower board. Check continuity. Treadmill will operate without sensor but cannot Auto-
calibrate. Calibrate manually.
3. Replace RPM sensor
