ERROR 74, 75, 76, 77
Flat Belt Count, Mismatched console
Applies to
AMT12, all models
Issues Symptoms
The upper PCA and lower PCA compare the stride count record written on each EEPROM.
# Error 74: The lower PCA stride count is less than that of the upper PCA, and the upper PCA is less than 30,000 strides.
# Error 75: The lower PCA stride count is less than that of the upper PCA, and the lower PCA is less than 30,000 strides.
# Error 76: The lower PCA stride count is greater than that of the upper PCA, and the upper PCA is greater than 30,000 strides.
# Error 77: The upper PCA stride count is greater than that of the lower PCA, and the lower PCA is greater than 30,000 strides.
The events will be recorded to the error log during the workout summary and the lower PCA stride count record is written to the upper PCA EEPROM.
The most likely cause of these errors is that upper PCA or lower PCA was replaced during troubleshooting, utilizing the related board from an adjoining unit.
Troubleshooting steps
In general, no action is needed. This is an event that has been recorded to the error log.
Troubleshooting Note:
If you are swapping a PCA to perform troubleshooting, note the process below to prevent the stride count odometer from being prematurely overwritten.
# When you stop pedaling the AMT, the AMT will pause for 20 seconds, and then give a 10 second workout summary (which is when the records are written between the PCA’s). After the PCA is replaced and testing the AMT is complete you will need to unplug the data cable from either PCA within the 20 second pause period to prevent the summary from happening. If the AMT is prevented from going into the summary, the stride count will not be overwritten.
# When testing is complete make sure that each PCA board is replaced in the original unit from which it was removed. The only exception to this would be if you find a bad board that needs to be replaced.
# All of these functions will place a code in the error log, and they should be cleared before returning the unit to use.

ERROR 78, 79
Flat Belt Replacement
Applies to
AMT 12
Issue Symptom
The AMT12 flat belt system has a predetermined life span of 100,000,000 (100M) strides. The AMT12 maintains a stride count independent from the overall machine stride count. When this stride count reaches 90,000,000 (90M) strides, error 78 is recorded in the error log and displays a message, alerting that the flat belts need to be replaced soon. Normal workout operation is still available. When the stride count reaches 100M strides error 79 is recorded in the error log and displays a message, indicating that the flat belts must be replaced. If this occurs during a workout the user will be able to continue the workout until ended. No further workouts will be allowed until the stride count is reset in the console after the belts have been replaced.
Troubleshooting steps
1. Replace all four flat belts.
2. Reset the flat belt stride odometer.

ERROR 80, 81, 82, 83
Phase A or B Missing / Incline Control
Applies to
P30 Console, all products
Issue Symptoms
The main symptoms for these errors are lack of control for incline and speed (TRM) or resistance and crossramp (EFX, AMT). These errors will occur upon “lack of” or broken hardware communication. The sensors communicate through an 8-pin connection. Pins 1-3 are incline controls; pins 6-8 are 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.
# Error 81 - Incline (or crossramp) will stop at current incline. Error 81 is displayed when there is a missing incline signal on pin 3
# Error 82 - Speed will decrease at 0.1mph per key press until belt stops. Error 82 is displayed when there is a missing drive signal on pins 6 or 7
# Error 83 - Speed will remain at current speed. Error 83 is displayed when there is a missing drive signal on pin 8.
The most likely causes for these errors are a loose or disconnected connector to the upper PCA, 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 user 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.

ERROR 85
No Dynamic Brake Resistor Detected
Applies to
TRM800.v2
Issue Symptoms
The dynamic brake resistor (DBR) is designed to absorb the excessive current produced by the drive motor turning faster than it is being driven. When the Machine Controller boots up, it checks for the resistor to be plugged in. If it detects an open an error 85 will be displayed. It will only be displayed briefly when power is applied. The most probable cause for this is the DBR not being plugged in, or it is open due to overheating or a broken cable.
Troubleshooting steps
1. Visually determine if the DBR is connected to the MC.
2. Use a multimeter and measure the DBR. It should read 100 ohms. If this is significantly higher than 100 ohms replace the resistor.

ERROR 86,87
Console Mismatch
Applies to
TRM800.v2 P10, P30
Issue Symptoms
The P10 and P30 for the TRM800.v2 require different software versions than the TRM800.v1 for communicating with the Machine Controller. Installing a console with mismatched software between the console and MC will cause an error to be displayed.
# Error 86 occurs when TRM800.v1 console software is connected to TRM800.v2 MC software.
# Error 87 occurs when TRM800.v2 console software is connected to TRM800.v1 MC software.
Troubleshooting steps
Update the software in the console to the correct version.
