    In order for ramp and resistance levels to be selectable the unit must be in use, that is, the system must be receiving a normal pulse from the reed switch speed sensor. The 5.17 EFX operates from a 12 Vdc source. An AC to DC power adapter is provided with the EFX. See Diagram 1.1.
  • Page 3 To remove power from the EFX 5.17, the power adapter’s power cord must be disconnected from the wall outlet. Always ensure that the EFX 5.17 power adapter is unplugged from the wall outlet when you inspect or adjust the EFX 5.17, or when you isolate, remove, or replace a EFX 5.17 component.

  • Page 19: Circuit Description

    5.17 Elliptical Fitness Crosstrainer Procedure 5.3 - Troubleshooting the Speed Sensor Circuit Description The speed sensor is a reed switch. A magnet is mounted on the step up pulley. The magnet passes the speed sensor once per revolution. The output from the speed sensor is a 5 Vdc square wave, the frequency of which indicates the operating speed.
  • Page 20 5.17 Ellipitical Fitness Crosstrainer lower PCA. The measurement should be approximately 5 Vdc. If the measurement is correct, skip to step 4. If the voltage is missing or significantly low, disconnect the speed sensor and repeat the measurement on the J2 connector. If the measurement is now correct (5 Vdc), replace the speed sensor.
  • Page 21 5.17 Elliptical Fitness Crosstrainer Procedure 5.4 - Troubleshooting the Lift System Note: The lift motor is disabled when the EFX is not being used.

If the new part does not correct the problem, replace the original part.
  • Page 23 5.17 Elliptical Fitness Crosstrainer Procedure 5.5 - Troubleshooting the Magnetic Resistance System Note: If the control circuit does not see an output from the speed sensor, the mechanism that changes the resistance level is disabled. Therefore, the speed sensor must be operative and the unit must be in use, before the resistance level can be changed.
  • Page 24 If you have performed the above tests in step 6 and 7 and the magnetic resistance system still does not move when powered up, call Precor Technical Support. In order for the power up procedure (step 4) to be successfully completed, the magnetic resistance system must receive pulses from the infrared photo optic sensor and receive a signal from the home switch.
