Incline Lift System Troubleshooting

The incline Lift system consists of an
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
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.
