Troubleshooting the Incline System
Incline System Description:
The Lift system consists of an AC line voltage driven lift motor
(120VAC or 240VAC), and an internal 1 K W (Ohms) potentiometer for lift
position monitoring. It is important when you start to troubleshoot the
lift system to determine if the problem is due to an inability to move
the lift, or an inability to monitor the lift position.
This will determine whether you need to troubleshoot the AC voltages
going to the motor windings, or if you need to troubleshoot the DC
voltages and/or ohm readings from the potentiometer. The error log will
help determine which is causing the issue.
Press and hold the reset key for at least 6 seconds, if there are
errors logged in the error log this action will take you into the error
log.
If there is an error code for a lift system error (Error 40 through 45)
logged in the error log, go to the appropriate error code
troubleshooting page and follow the steps for that error.
Note: All resistance measurements must be performed with power
removed from the treadmill. Performing resistance measurements with
voltage applied may damage your ohmmeter.
Operation of lift motor for testing:
Most Precor treadmills require the running belt to be moving to operate
the lift. For this reason it is recommended that the servicer use the
Machine Tests within the "Hardware Validation" mode (accessible through
Pause-5-1-7-6-5-7-6-1) to check lift operation.
