11. If the display does not indicate that the speed should be increasing when the
SPEED
S
key
is pressed, the problem is in either the keypad or the upper PCA. Troubleshoot the keypad
per Procedure 5.1. If the keypad is defective, replace the console per Procedure 6.10.
12. If the keypad is good and the display still does not indicate that the speed should be
increasing when the
SPEED
S
key is pressed, replace the upper PCA per Procedure 6.11.
13. If the display does not indicate that the speed should be increasing when the
SPEED
S
key
is pressed, bypass the interconnect cable with a known good interconnect cable. It is not
necessary to install the bypass cable, just connect it between the upper PCA and lower
PCA. If the drive motor functions normally with the bypass cable installed, replace the
interconnect cable per Procedure 6.12.
14. If the drive motor does not function normally with the bypass cable installed, replace the
lower PCA per Procedure 6.5.
15. If you have performed all of the procedures above and have been unable to correct the
problem, call Precor customer support.
