Precor Error LS, Speed Sensor Signal Missing Probable Cause 1. Intermittent or open connection of the speed sensor (reed switch) wiring.
2. Reed switch is defective or has intermittent connection.
3. Drive motor brushes are bad.
4. Lower PCA is bad.
Corrective Action

1. Inspect the speed sensor (reed switch) wiring for damage or poor connection to the lower PCA. Replace damaged wiring or reset connection as necessary.

Precor Error Code 23 Error Code: 23 Manufacturer: Precor
Model: All Models
Error Description: Error 23, Motor Pulses Missing after Start Up - Indication that the speed sensor signal was lost while the unit was in operation. Possible Reason:

1. The line of sight between the speed sensor and the speed sensor target is obstructed.
2. Incorrect gap between the speed sensor and the speed sensor target.
3. Incorrect adjustment of the speed sensor potentiometer (when equipped).
4. Intermittent connection of speed sensor or drive motor wiring.
5. Badly worn drive motor brushes not able to make proper contact with drive motor commutator.
6. Faulty lower PCA.
7. Faulty interconnect cable between upper and lower PCA.
8. Faulty upper PCA.

Recommended Action:

1. Using a static safe vacuum cleaner, carefully vacuum out the drive motor compartment. Be sure to thoroughly clean the area between the speed sensor and the speed sensor target.
2. Inspect the gap of the speed sensor to the speed sensor target. Proper gap is 3/16" and the speed sensor photo eye should be aimed at the larger portion of the targets wedge shaped section. If unit has a magnetic speed sensor, the gap between the end of the sensor and the flywheel tooth needs to be 3/16".
3. Locate the speed sensor potentiometer (when equipped) on the lower PCA. Set the speed sensor potentiometer to mid-range. Start the treadmill and increase speed to 6 mph. Carefully adjust the speed sensor potentiometer until the treadmill is operating the smoothest. Increase the speed to full speed and again adjust the speed sensor potentiometer until the treadmill is operating the smoothest. These two adjustments are typically small and are generally only a matter of fine tuning.
4. Test all wiring and wire connections of the speed sensor and drive motor. Replace or repair necessary wire connections or wiring.
5. Inspect and replace drive motor brushes if necessary.
6. Determine if the lower PCA is bad by swapping with a known good lower PCA.
7. Determine if the interconnect cable is bad by swapping with a know good cable.
8. Determine if the upper PCA is bad by swapping with a know good upper PCA.

No communication between the product and the Touch Control Panel
Corrective action: Try the following:
1. Check the event log at the EWS support pages to see if there is another SE (for instance 07:10) and troubleshoot the problem more accurately
2. Turn off the product and turn on again, and check to see if the error remains.
3. Upgrade the firmware
4. Check the condition of the USB cable, check it is not damaged or incorrectly connected.Reconnect USB cable (from Engine PCA to the Interconnect PCA or from Interconnect
PCA to the Touch Control Panel
5. Replace the USB cable
6. Replace the Interconnect PCA, see Interconnect PCA on page 315.
7. Replace the Engine PCA see EE Box on page 281
8. If the error continues, replace the Touch Control Panel

Precor Error LS, Speed Sensor Signal Missing Probable Cause 1. Intermittent or open connection of the speed sensor (reed switch) wiring.
2. Reed switch is defective or has intermittent connection.
3. Drive motor brushes are bad.
4. Lower PCA is bad.
Corrective Action

1. Inspect the speed sensor (reed switch) wiring for damage or poor connection to the lower PCA. Replace damaged wiring or reset connection as necessary.
2. Using an ohm meter, test the reed switch while rotating the drive pulley. The reed switch will close when the magnet passes in front of it.
3. Inspect the drive motor brushes and replace if necessary.
4. Test unit with a known good lower PCA. Replace lower PCA if necessary.

Precor Error Code LS

Precor Error 28, Temperature Too High Probable Cause 1. The lower PCA cooling fan is clogged.
2. The lower PCA cooling fan is inoperative.
3. The running belt and/or deck are badly worn.
4. The lower PCA is bad.
5. Drive motor is shorted or de-magnetized causing a high power demand.
Corrective Action

1. Inspect the fan mounted on the lower PCA for dust/debris buildup. Clean if necessary, ensuring the fan spins freely. Some lower PCA's do not have a cooling fan and others may have the fan mounted on the underside of the lower PCA making it not as visible.
2. The fan was free of dust or debris but does not spin. Make sure that the fan wiring is secure and properly connected to the lower PCA. If no obstruction to the fan and the wiring is good but fan still doesn't turn, replace the lower PCA.
3. Check the amp draw using a clamp on AC volt-amp meter during loaded and no load conditions; compare the values to a similar treadmill that is known to have a good running belt and deck. Replace the belt and/or deck if necessary. Don't forget, some units have a double sided deck which means it may be flipped over rather than replaced if it has an unused side.
4. Test unit with a known good lower PCA. Replace lower PCA if necessary.
5. Test unit with a known good drive motor. Replace drive motor if necessary.

Precor Error Code 28

Precor Error 30, 31, 32 and 33, Communications Error Probable Cause 1. Bad interconnect cable between upper PCA and lower PCA.
2. Interconnect cable is mistakenly plugged into the CSAFE connector at the upper PCA.
3. Elliptical 5.17 equipped with old software version 1.01 in upper and lower PCA.
4. Upper and lower PCAs have mismatched software.
5. Another component plugged onto the PCA is overloading the +5VDC power supply.
6. Bad lower PCA.
7. Bad upper PCA.
Corrective Action

1. Test unit with a know good interconnect cable or test the interconnect cable for continuity. Replace interconnect cable if necessary.
2. Disconnect the interconnect cable from the CSAFE connector and attach to the proper position on the upper PCA.3.
3. Replace the upper and lower software of the 5.17 elliptical with the most current versions.4.
4. If one of the PCAs is found to have software version 1.01, replace it with the most current software version.
5. Disconnect all components from the upper and lower PCA leaving the data cable connecting between the upper and lower PCAs and the AC power going to the lower PCA. If the unit shows any error other than the error 3x, reconnect components one at a time. Reset power between each newly connected component until the error 3x reappears. Whichever component was last connected when the error 3x reappears, is the cause for the error. Replace the faulty component.
6. Test unit with a known good lower PCA. Replace the lower PCA if necessary.
7. Test unit with a known good upper PCA. Replace the upper PCA if necessary.
