Incline Lift System Troubleshooting
The incline Lift system consists of an AC voltage driven lift motor (120 Vac or 240 Vac) and an
internal 1 K ohm potentiometer for lift position monitoring.
The first step in troubleshooting the lift system is to review the error log for any lift system error
codes. Then determine whether the problem is related to a lift movement issue or a lift position
sensor issue. If the lift does not move, then the problem is most likely related to defective lift
motor windings or the

lift motor control circuitry. if the issue is with the lift platform pos-
ition, then most likely the issue is due to a defective lift position sensor potentiometer.
Use the lift motor related error codes 40 thru 45 to help isolate and repair the fault.

ERROR CODE DESCRIPTION
40 No Lift Motion Detected
42 Lift Position Out Of Range
44 Un-commanded Lift Motion
45 Lift Moving In the Wrong Direction
Troubleshooting Procedure
Error code events are generated when the lift system has been commanded to move and no
and/or incorrect lift motion has been detected.
Review the machine Error Log or CPA

Event Log and note any lift system related error codes
(codes 40 thru 45). Then use the Error Code and Troubleshooting Guide to learn about these
error codes and procedures to troubleshoot and repair the issue, see Error Code
Troubleshooting Guide .
Operating the lift motor for troubleshooting
In normal operating mode, the treadmill requires the running belt to be moving to operate the
lift. Therefore, it is recommended to operate the lift motor from the service Hardware Val-
idation > Machine Test > Incline Test diagnostic test (see
"Hardware Validation Service Menu
(51765761)" on page 23 ) .
The Incline Test diagnostic test will allow the incline to be changed without the running belt
movement requirement. The Incline Test also allows lift incline control during an out-of-range
lift position fault. This allows recovery from an out-of-range fault condition.
