9.25, 9.25i Treadmill Procedure 5.3 - Troubleshooting the Lift System System Description The lift system is powered by a 120 Vac lift motor that uses two independent motors windings, one operates the motor in an upward direction and one operates the motor in a downward direction. The motor contains a 10 KΩ or 1KΩ potentiometer (depending on manufacturer), driven by the motor, that indicates lift position. AC power to operate the lift motor is provided by a pair of triacs.
9.25, 9.25i Treadmill 8. Remove the P2 connector from the lower board. Using an ohmmeter, measure between terminals 1 and 3 of P2, between terminals 1 and 2 of P2 and between terminals 2 and 3 of P2. The measurements should be approximately 14.5Ω, 14.5Ω and 29Ω, respectively. If any of the measurements are significantly low, replace the lift motor. 9. Re-insert the P2 connector in the lower PCA. Set the treadmill circuit breaker in the “on” position.
9.25, 9.25i Treadmill Procedure 5.4 - Troubleshooting the External A.C. Power Source It is extremely important that any Precor treadmill be connected to and operated on a dedicated 20 amp A.C. circuit. A 20 amp dedicated circuit is defined as: a circuit fed by a 20 amp circuit breaker that feeds a single load. A treadmill operating from a non-dedicated circuit or a circuit breaker of less than 20 amps capacity will not have the necessary power available to operate normally under higher load conditions.
9.25, 9.25i Treadmill 2. The circuit breaker correctly feeds a single A.C. outlet but the neutral is common between several A.C. outlets. The common neutral lead must be removed from treadmill’s A.C. outlet and a new neutral lead from the treadmill’s A.C. outlet to the A.C. neutral distribution bar must be added. 3. Both the hot and neutral leads feed several A.C. outlets. Both the common neutral and hot leads must be removed from treadmill’s A.C.
