Incline System Troubleshooting
The incline system consists of an
AC
1
line voltage driven lift motor (120
VAC
2
or 240 VAC),
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.
Related Error Codes
Incline system error codes: 40 through 45.
Refer to the
Error Code Troubleshooting Guide
for error code description and troubleshooting
information.
Procedure
Determine whether you need to troubleshoot the AC voltages going to the motor windings, or
if you need to troubleshoot the
DC
3
voltages and/or ohm readings from the potentiometer.
The error log will help determine which is causing the issue.
Check the error log for INCLINE system error codes, press and hold the reset key for at least 6
seconds to access the error log.
If there is an error code for a lift system error logged (Error 40 through 45), go to the
and follow the troubleshooting information.
CAUTION
: All resistance measurements must be performed with power removed
from the machine. Performing the resistance measurements with voltage applied to
the circuit can damage the multimeter.
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 "Hardware Validation" - Machine Tests (see ) to
verify lift operation.
