Figure 120: Flat Belts - Precor AMT Series Service Manual

The stride count odometer is now stored on both the upper PCA and Lower
PCA. The dual memory locations allow the stride count to be transferred
in the event that an upper PCA or lower PCA is replaced. If the upper
PCA is replaced, the stride count stored on the lower PCA will be
written to the new upper PCA. If the lower PCA is replaced, the stride
count stored on the upper PCA will be written to the new lower PCA.
Note: When the belts are replaced, it is required that all 4 flat belts be replaced
at the same time.

Precor recommends not swapping lower and upper PCA boards to
troubleshoot, but if swapping is the only option to isolate a problem,
swap only one PCA board at a time.
If you are swapping a PCA board 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). After the PCA board is replaced and testing the AMT is
complete you will need to unplug the data cable 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 (70-79) in the error log,
and they should be cleared before returning the unit to use.
The following table shows the possible belt and PCA board swapping
event codes.
