Precor Error Code 80, 81, 82, 83 Motion Controller Switch Errors

Feb 10, 2022

Applies to

P30 Console, all models

Issue symptoms

The main symptoms for these errors are lack of control of the ramp incline and/or speed (TRM) or resistance (EFX, AMT). These errors will occur whenever there is either poor or missing hardware communication between the motion controller and sensors. The motion controller to sensor interface cable uses an 8-pin connector. Pins 1-3 are incline controls; pins 6-8 are either drive (speed or resistance) controls.

• Error 80: Incline (or CrossRamp) will stop at current incline. Error 80 is displayed when there is a missing incline signal on pins 1 or 2. Restart is not needed to clear the error; self-recovery is possible when the control is returned to the center position.
• Error 81: Incline (or CrossRamp) will stop at current incline. Error 81 is displayed when there is a missing incline signal on pin 3. Restart is not needed to clear the error; self-recovery is possible when the control is returned to the center position.
• Error 82: Speed will decrease at 0.1 MPH for each key press until the belt stops. Error 82 is displayed when there is a missing drive signal on pins 6 or 7. Restart is not needed to clear the error; self-recovery is possible when the control is returned to the center position.
• Error 83: Speed will remain at current speed. Error 83 is displayed when there is a missing drive signal on pin 8. Restart is not needed to clear the error; self-recovery is possible when the control is returned to the center position.

The most likely causes for these errors are a loose or disconnected connector to the UPCA, damaged cables, or a faulty machine control.

Troubleshooting steps

1. Check the error log for multiple occurrences of the error with the same odometer reading. Clear the error log, and cycle power to the machine.
2. Open the console and check the connectors. Ensure that they are securely connected to both the upper PCA and to the machine control.
3. Check the cable for visual damage; use an ohmmeter to verify continuity on each line. Replace both the cable and machine control if a fault is found.
4. Inspect the machine control for corrosion or damage and replace both the machine control and cable, if any damage is found.
5. Review the software version of the P30. If the exerciser or facility owner states the issue is related to the machine controls not working as designed, the P30 software may need to be updated in addition to the replacement of the machine control and cable assemblies. Current software versions are available on the Precor Connection website.
