Incline System Troubleshooting

The incline system consists of an ACAlternating Current: electric current which periodically reverses direction between positive and negative polarity. line voltage driven lift motor (120 VACvoltage in an alternating current circuit 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 DCDirect Current: electrical current that only flows in one direction. 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 Error Code Troubleshooting Guide 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.
