Machine Controls Troubleshooting
Applies To: P30 consoles
The main symptoms caused by bad machine incline and speed controls are lack of control for
incline and speed (treadmills) or resistance and crossramp (ellipticals & AMTs). Machine con-
trol error codes will occur when the machine controls no longer provide reliable mechanical
inputs to the console machine control software. The controls communicate through an 8-pin
connection. Pins 1-3 are incline controls; pins 6-8 are drive (speed or resistance) controls.
Using dielectric grease
A common issue with machine controls is pin contact contamination in cable connector due to
sweat and moisture. Verify that the machine control cable connector contacts are not con-
taminated. Clean contacts and apply a thin coat of dielectric grease to the pin contacts.
The following error codes can be caused by bad machine control hardware:

ERROR CODE DESCRIPTION
80 Error 80 - Incline (or crossramp) will stop at current incline. Error 80 is dis-
played when there is a missing incline signal on pins 1 or 2. Restart is not
needed to clear the error, self-recovery possible when the control is
returned to the center position.
81 Error 81 - Incline (or crossramp) will stop at current incline. Error 81 is dis-
played when there is a missing incline signal on pin 3. Restart is not
needed to clear the error, self-recovery possible when the control is
returned to the center position.
82 Error 82 - Speed will decrease at 0.1 mph per key press until 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 possible when the
control is returned to the center position.
83 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 possible when the control is returned to the center
position.
