ERROR 01, 02, 03, 04 - Memory, Ram & EEPROM Test Errors
Applies to
All cardio equipment
Issue Symptoms
Errors 00 through 04 check upper PCA memory locations, RAM memory locations, and the EEPROM checksum during the power up test sequence. If a fault is found during the power up test sequence, the appropriate error code will be displayed. While rare, these messages may display intermittently due to external causes. If the unit's AC input significantly dips during the power up test sequence the test could fail resulting in triggering one of these errors. In addition, treadmills operating on non-dedicated branch AC circuits may see these errors on an intermittent basis.
Troubleshooting steps
1 Reproduce the error and evaluate
a. Turn off unit.
b. Turn on unit. Repeat.
c. If the error message is consistently displayed when the unit is powered up, replace the upper PCA

ERROR (05) - Key In The Operated Position At Power Up
Applies to
All consoles
NOTE: Error 05 has not been displayed on Precor equipment since 2003. It was replaced by the simpler “Stuck Key” message, and is not recorded in the error log.
Issue Symptoms
The power up test sequence has detected a key in the operated condition. A permanently stuck key inhibits the correct operation of the unit. Likely causes are liquids present on a touch sensitive display, or a key in the display housing is stuck in the operated condition. Less likely but possible is a failure on the upper PCA.
Troubleshooting steps
1. Check for visible liquid
2. Wipe off any visible liquid from the surface of the touch sensitive display.
3. Restart the unit. If error 5 is no longer present, the liquid was the cause.
4. Test the keypad
5. Turn off the unit.
6. Remove the keypad connector cable from the upper PCA.
7. Restart the unit, if error 5 is no longer present, the keypad is the cause. Note that the keypad is typically part of the display housing.
8. Replace the display housing to correct the problem.
9. Test the upper PCA
10. Turn off the unit.
11. Remove the keypad connector cable from the upper PCA.
12. Restart the power up sequence, if error 5 is still present, the upper PCA is the cause.

Error 10 - Line Frequency Out Of Acceptable Range
Applies to
Treadmills built since 2006
Issue Symptoms
The AC line frequency must be either 50Hz or 60Hz for Experience treadmills built 2006 2013, and between 45Hz and 65Hz for TRM800 v2 (2014 onward). Error 10 is triggered if the line frequency moves beyond these acceptable ranges, or if electrical noise is generated causing a perceived change in frequency. Error 10 can also be caused by electrical wiring and supply issues, such as shared neutrals or AC hot and AC neutral wires being reversed. If facility power is lost, and a backup generator turns on the frequency can be off for a short time, causing Error 10.
Troubleshooting steps
Verify electrical supply
1. Treadmills must be installed on an AC 20 amp dedicated branch circuit. Both the hot and neutral leads must be dedicated to the treadmill. If another piece of equipment is sharing a circuit with the treadmill it can create enough electrical noise to make AC line frequency identification impossible. The treadmill’s AC
circuit must be reconfigured as a completely dedicated 20 amp circuit.
2. Most line frequency detection systems monitor the AC line frequency on the hot AC line. In the case of a reversed 120 V.A.C circuit, the monitoring is taking place on the neutral (ground) side of the AC line. Many of the monitoring systems are incapable of detecting line frequency on the neutral wire. It must first be determined if the reversal is in the AC wiring feeding the treadmill or in the treadmill internal wiring. The hot and neutral wires can be verified by measuring each in reference to AC (green wire) ground.
3. Even though unlikely, the AC line frequency could actually be out of acceptable limits. This is more likely to occur in countries where AC power systems may not be well developed and controlled. There may be little that can be done about this condition. If a generator is used during a power outage, during the time the generator is coming up to speed the line frequency may be detected as incorrect.
4. Sometimes AC being fed into the distribution system is too electrically noisy to allow correct line frequency identification. This can be caused by other equipment within the AC distribution system creating the electrical noise. Identifying the source of the electrical noise can be difficult. There may be little that can be done about this condition.

ERROR LS - Speed Sensor Signal Missing
Applies to
9.23, 9.27
Issue Symptoms
This error is displayed in the display’s TIME window when the drive motor speed signal is not received from the speed sensor for eight consecutive seconds. When the LS error occurs, all drive motor and lift motor motion is halted and the display is blanked except for the error display. The treadmill utilizes a reed switch and two magnets in the drive roller pulley as a speed sensing system. The most likely causes for this are the speed sensor wiring having an intermittent or open connection, an intermittent or defective reed switch, or bad drive motor brushes. Least likely but possible is a bad upper PCA.
Troubleshooting steps
1 Check the reed switch wiring and connection to the lower PCA.
2 Check the reed switch using an ohmmeter while rotating the drive pulley. The reed switch will close when
a magnet passes in front of it.
3 Replace both drive motor brushes.
4 Substitute a known good upper PCA to determine if the upper PCA is bad.

ERROR E2 - Lift Error
Applies to
9.23, 9.27
Issue Symptoms
This error is displayed in the display’s TIME window indicating an incline problem. This error will occur if the incline is unable to move or if the incline position potentiometer is not functioning. When the E2 error occurs, all drive motor and lift motor motion is halted and the display is blanked except for the error display.

When the E2 error occurs, all drive motor and lift motor motion is halted and the display is blanked except for the error display.
Troubleshooting steps
1 If the lift motor has drifted too low, disconnect the motor from the lift assembly and adjust the jack screw until the motor is in range. Perform the appropriate lift motor calibration procedure. If the motor continues to drift low, replace the motor.
2 Inspect the lift motor connector, verifying the pins are secure in the connector. Attach the connector to the lower PCA and ensure that it is locked into the header.
3 Enter Diagnostics, Machine Test, Incline or Crossramp test. Run the lift all the way extended and back to minimum. The A/D number should climb and decrease smoothly during the test. If not, replace the lift motor.
4 While in the Incline or Crossramp test scroll to see Glitches, and run the lift to both extremes. Glitches are anomalies recorded by the lower board during lift movement, indicating a possible or existing problem with the internal potentiometer or the gearing that turns it. Very few if any glitches should be recorded. If greater than 50 glitches are recorded during a full movement to either extreme, replacement of the lift motor is necessary.
