Cybex 525T Treadmill Part Number
Error 140: Can not find home position on power-up
Cause:
The Drive Controller did not encounter the incline zero switch within timed limits on power-up. The
treadmill will function normally, with the incline disabled. The display will shut down power to the incline
motor, and show dashes for incline until the drive has made a satisfactory calibration.
Service:
Note that V1.26 and later drive controller software improve the Error 140 conditions.
• Ensure the 50Hz/60Hz selection in Setup is correct for the line frequency used.
• Check the incline motor for binding, functioning cam/switch, and wiring.
• Verify the switch activates at 0% Grade.
• Calibrate incline motor.
