If the lift motor drive screw rotates the lift calibration number will no longer be The lift calibration number must be and the distance measurement must be correct for the lift calibration to be correct.

Do not exit the diagnostic program in the normal manner. Exiting the diagnostic program will cause the lift to self center and invalidate the lift calibration just performed. Skip to step Raise the ramp assembly to a convenient height and slide the ramp end cap into the ramp assembly.

Thoroughly test all lift related functions per Section Four. Diagram 5. Remove the s front cover per Procedure 7. Remove the four screws that retain the lift yoke to the ramp assembly. Support the lift motor and ramp assembly as you separate the lift yoke from the ramp assembly. Do not exit the diagnostic program in the normal Page 24 C Elliptical Fitness Crosstrainerl manner. Raise the ramp assembly to a convenient height and slide the lift yoke into the ramp assembly.

Remove both stairarms as described in Procedure 7. Operate the unit by rapidly rotating a crankarm by hand. As the unit operates watch the drive belts for proper alignment. The belts should operate parallel to each other and the belts should maintain even spacing. If the belts are not correctly aligned Skip to step 13 6. Refer to Diagram 5. The right and left tension bolts have locking tabs. If necessary, use pliers to bend the locking tabs out of the way so that the bolts can be turned.

If the step up pulley belt is out of alignment to the right, continue with step 9. If the step up pulley belt is out of alignment to the left, continue with step Repeat step 8, alternating between the left and right tension bolts until the alignment is correct. Continue with step Repeat step 11, alternating between the right and left tension bolts until the alignment is correct. Page 26 C Elliptical Fitness Crosstrainerl Belt tension must now be checked and if necessary corrected.

Remember, if it is necessary to change the belt tension, the belt alignment must be maintained. Lay a straight edge along the length of the belt and beside the belt gauge. Slide one of the o-rings up against the shoulder of the belt gauge. Press downward on the belt gauge, causing the belt to deflect.

Read the deflection on the belt gauge at the edge of the straight edge. Read the tension across the top edge of the o-ring. If the belt is correctly tensioned the gauge will read between 19 and 21 pounds. If the tension in step 13 is correct skip to step Otherwise continue with the next step. If the locking tabs on the right and left tension bolts have not been straightened, use pliers to bend the locking tabs out of the way so that the bolts can be turned.

The belt tensioning gauge reads less than 19 pounds THEN Verify that the belt alignment is still correct by performing the procedure in step 4. The input pulley tension must now be checked and corrected, if necessary. There is not sufficient room to use the belt tension gauge to set the input pulley belt tension. It will be necessary to use the correctly tensioned step up belt as a comparison to set the input belt tension. Page 28 C Elliptical Fitness Crosstrainerl Using your finger, press in on the center of the lower span of the input belt.

Compare the pressure required to deflect the input belt to the pressure required to deflect the step up belt. Loosen the stub tensioner axle nut slightly. Turn the stub tensioner adjustment bolt clockwise to increase or counterclockwise to decrease the input belt tension.

Remove the interconnect cable cover. See Diagram 7. Remove the rear cover. For convenience the upper interconnect cable is the cable that attaches to the upper PCA and the lower interconnect cable is the cable that connects to the lower PCA. There is an access hole in the bottom of the main frame tube that allows access to the junction of the upper and lower interconnect cables. Disconnect the upper interconnect cable from the upper PCA and the lower interconnect cable.

Connect a known good upper interconnect cable from the lower interconnect cable to the upper PCA. Route the cable outside of the unit at this time. Check operation as described in Section Four. If the unit operated correctly when the new interconnect cable was installed, the original Page 30 C Elliptical Fitness Crosstrainerl interconnect cable is bad. Install a new interconnect cable per Procedure 7. If the unit does not operate properly, continue with the next step. Reconnect the original upper interconnect cable to the upper PCA.

Troubleshooting the Lower Interconnect Cable Remove the shield from the lower PCA. Remove the interconnect cable from the lower PCA.

Access the diagnostics program per procedure 3. If the key s necessary to access the diagnostic program is not functioning, skip to step Test the keypad per Procedure 3. If all of the keys test good, the problem may be user error or a key function that is normally disabled during a particular user program.

If one or more keys do not function correctly, either the keypad display housing or upper PCA could be defective. Replace the display and repeat step If the display housing did not correct the problem, re-install the original display housing and replace the upper PCA.

A magnet is mounted on the right hand crankarm and passes the hall effect sensor once per revolution. The output from the speed sensor is a 5 Vdc square wave, the frequency of which indicates the operating speed. When a square wave output is not being generated by the speed sensor the system assumes the unit is not in use and removes resistance from the eddy current magnet system.

Set the unit in the manual program and operate the unit. If a stride rate is not displayed, the speed sensor is not operative. We shall use the presence of a stride rate to determine when the speed sensor is functioning normally. If the stride rate is not being displayed in step 1, verify that a magnet is installed in the crankarm associated with the speed sensor and that the south pole faces outward.

The magnet polarity may be checked with another magnet with known poles or a compass. The north pole of the test magnet or the south facing needle should be attracted to the speed sensor magnet.

Using a DC voltmeter, measure the voltage between terminal 1 red wire and terminal 5 black wire on the speed sensor connector.

The measurement should be approximately 5 Vdc. If the voltage is correct, skip to step 5. If the voltage is missing or significantly low, disconnect the speed sensor connector from the speed sensor and repeat the measurement on the connector.

If the voltage is now correct, replace the speed sensor. If the voltage is still missing or significantly low, continue with step 4. Repeat the measurements in step 3 at terminals 1 and 5 of J8 on the lower PCA. If the voltage is missing or significantly low, replace the lower PCA. If the voltage is now correct, replace the speed sensor assembly. Slowly rotate the flywheel as you monitor the voltage. The measurement should switch between approximately 0.

If the voltage is correct, skip to step 6. If the voltage does not switch the voltage is constantly low or high as the flywheel is slowly rotated , replace the speed sensor. If the voltage switches correctly, but the stride rate is still not displayed when the unit is operated, replace the lower PCA.

Page 39 C Elliptical Fitness Crosstrainer 6. Repeat the measurement in step 5 at terminals 1 and 2 of J8 on the lower PCA. If the voltage is missing or significantly low, replace the speed sensor assembly. If you have performed all of the above tests and the stride rate is not displayed when the unit is operated, there are three parts that could cause the problem. There are not any good tests to check these parts other than substituting a known good part.

Replace only one part at a time. If the new part does not correct the problem, replace the original part. If you have performed all of the above tests and the speed sensor is still not functioning, call Precor Technical Support. The speed sensor must detect motion in order for lift operation to be enabled. In the following procedures, when lift motor movement is being tested the stairarms must be in motion. Before performing this procedure, ensure that the speed sensor is operating normally per Procedure 6.

Note: On version 1 units manufactured prior to August 16, a single lift connector J4 was used. If the lift motor will not move skip to step 7. If the lift motor moves and an error occurs continue with step 2. Access the diagnostics program per Procedure 3. If the lift calibration number is 0 or skip to step 3. Operate the lift, if the lift calibration number does not increment as the lift moves, skip to step 3. If the calibration number increments as the lift moves, re-calibrate the lift per Procedure 5.

If recalibration does not correct the problem, continue with step 3. Using an ohmmeter, measure between terminal 1 brown or green wire and terminal 3 orange wire of the J4 connector on the lower PCA.

Using an ohmmeter, measure between terminals 1 and 2 of J4 and measure between 2 and 3 of J4 on the lower PCA. If you have performed all of the above tests and an error still occurs when the lift motor operates, there are three parts that could cause the problem. Page 41 C Elliptical Fitness Crosstrainer 6. If you have performed all of the above tests and the lift system is still not functioning, call Precor Technical Support.

Remove the F2 2 amp slow blow fuse from the lower PCA. Measure the fuse with an ohmmeter. If the fuse is good, re-insert the fuse and skip to step 9. Before operating the lift motor it is necessary to perform a continuity test on the lift motor. Remove the J3 connector from the lower board. Using an ohmmeter, measure between terminals 1 and 3 of J3, between terminals 1 and 2 of J3 and between terminals 2 and 3 of J3.

The measurements should be approximately If any of the measurements are significantly low, replace the lift motor. Repair any wires or connections that are bad.

If the cable and connectors are good, replace the lift motor. Re-insert the J3 connector in the lower PCA. Using an AC voltmeter, monitor the voltage between terminals 1 and 2 red and white wires of the J3 connector.

The measurement should be approximately Vac line voltage. If the voltage is present and the lift motor moves normally, skip to step The voltage will only be present until such time as an error occurs. If line voltage is not present skip to step If line voltage is measured but the motor does not move, replace the lift motor. Monitor terminals 1 and 3 white and black wires of J3.

If the voltage is present and the lift motor moves normally skip to step The DC voltmeter should read approximately 5. The DC voltmeter should read near 0 Vdc and the ramp should go downward.

The DC voltmeter should read near 0 Vdc and the ramp should go upward. If all of the voltages in step 11 were correct but the ramp did not move in both directions replace the LPCA. If one or more of the voltages in step 11 were incorrect the problem is either one of the interconnect cables or the Upper PCA. Use Procedures 6. Therefore, when it is necessary to check the resistance or take voltage measurements in the eddy current system it will be necessary to slowly turn the flywheels to ensure that the power time out has not occurred.

There are three typical symptoms concerning the eddy current system. No resistance pedaling resistance , no resistance shortly after power up and incorrect resistance. If the problem is no resistance, continue with step 2.

If the problem is no resistance shortly after power up, test the speed sensor per Procedure 6. If the problem is incorrect resistance, skip to step 7. Using a DC voltmeter, check the voltage across the magnet. The voltage should measure approximately If the voltage is missing or significantly low, skip to step 4.

If the voltage is correct, continue with step 3. Check the magnet wiring per Diagram 8. If any of the magnet wiring is reversed or incorrect the resistance will be affected. If you have performed all of the above tests and there is still no resistance, call Precor Technical Support. If all of the wiring connections are good and there is still no resistance, there are three parts that could cause the problem.

If the new part does not correct the problem replace the original part. If the resistance is greater than normal, the cause could be mechanical rather than electrical. Replace the appropriate parts. Page 43 C Elliptical Fitness Crosstrainer 9. If the voltage is still significantly high or low, there are three parts that could cause the problem. If you have performed all of the above tests and the resistances are still incorrect, call Precor Technical Support.

Remove the fuses from the input power module. Check all four fuses with an ohmmeter. Replace any fuse that reads significantly high.

Replace the fuses in the power input module. The ohmmeter reading should be very high, megohms or greater. If the reading is good skip to step 11, otherwise continue with the next step. Replace any cut or nicked wiring. Check the line cord for nicked or cut wiring. Replace the line cord if necessary. If you have performed all of the above tests and are unable to resolve the problem, contact Precor customer support.
