Precor Error 50, Too Much Brake (Magnet) Current Probable Cause 1. Shorted or damaged wiring between the lower PCA and the eddy current magnet is the most common cause for this error. 2. Bad eddy current magnet. 3. Bad lower PCA. Corrective Action

1. Thoroughly inspect the eddy current wiring and connections ensuring that the wires are not shorted to the frame or shorted together. Repair or replace damaged wiring as necessary.
2. Disconnect the wires from the eddy current magnet. Using an ohm meter, check for approximately 100 ohms across the eddy current magnet terminals. If the reading is considerably low, replace the eddy current magnet. Measure ohms between each eddy current magnet terminal and the frame ground. You should have no resistance between the eddy current magnet terminal and the frame ground. If resistance is present this would indicate a partial short, replace the eddy current magnet.
3. If the eddy current magnet wiring and the eddy current magnet are both good from the above tests, replace the lower PCA.

Precor Error 05, Key Depressed at Power Up Probable Cause 1. A key is permanently depressed on the display. 2. An interface chip (IC) has failed in the upper PCA's keypad. 3. Liquid (cleaning solution or sweat) may be on the surface of a touch sensitive display. Corrective Action

1. Disconnect the keypad cable from the upper PCA. Reset power to the machine. If the Error 05 is eliminated, the keypad is the cause and should be replaced.
2. Disconnect the keypad cable from the upper PCA. Reset power to the machine. If the Error 05 still appears, the upper PCA* is the cause and should be replaced. *Upper PCA's most commonly do not come with software. Remove the software (chip) from the existing upper PCA prior to replacement and install into the new upper PCA.
3. Wipe away all liquid from the touch sensitive display. Reset power to the unit. If the Error 05 is eliminated, the liquid was the cause.

Precor Error 16, AC Input Voltage Too Low Probable Cause 1. AC input voltage is incorrect. 2. Treadmill operating on undersized AC wiring and/or is drawing high current. Corrective Action

1. Verify AC feed into the building's circuit breaker is correct and connected to the proper transformer tap.
2. The AC wiring must be sized to handle 20 amps of current over the loop length of the AC wiring. Voltage drop across the AC input wiring is a result of the length of the wire run multiplied by the amount of current being demanded by the treadmill. The longer the run and the higher the current the large the wire must be.Verify the unit is connected to an isolated and dedicated 20 amp circuit.

Precor Error 45, Lift Moving in Wrong Direction Probable Cause 1. Lift motor hysteresis. 2. Lower PCA is bad. Corrective Action 1. The error would usually occur when the lift was already in motion (usually downward) when a lift command in the opposite direction (upward) was made. Some lift motors used in production exhibited a very long turnaround time and the lift motor would still be moving in the original commanded direction while the control system was trying to move the lift in the opposite commanded direction. If the error continues to re-occur, replace the lift motor. 2. It is a rare condition, however if the lift moves in the opposite direction commanded, replace the lower PCA. Precor Error Code 45

Adjusting Tension on a Treadmill Running Belt It is necessary to properly tension a treadmill belt when it is replaced. After time, a belt can stretch and may begin to slip. When this happens, it is necessary to adjust the tension of the running belt to stop it from slipping. Manufacturers of treadmills generally agree on one of three procedures for how to tension a treadmill running belt.

1. Adjust for no slippage of the treadmill walking belt on the front roller (Often referred to as the "Stomp Test")
   1. This procedure works well for a previously installed belt that is now slipping.
   2. Underside of belt should be free of any glazing/wax buildup.
   3. Rollers must also be free of wax buildup.
   4. Be sure belt tracking/centering is correct before proceeding.
   5. The most popular speed for this adjustment is 2mph to 3mph.
   6. Try to slow the belt by applying pressure with your foot against the belt movement while grasping the handrails. If the running belt slow, slips or stops (and the front roller does not) adjust BOTH adjustment bolts 1/4 turn clockwise. Test again and repeat adjustment if necessary.
2. This procedure requires two belt gauges or calipers
   1. This procedure works well when installing a new belt.
   2. This procedure requires you to stretch the belt. Depending on the manufacturer*, this varies between .4 and .6 percent. A dial on the gauge or caliper will indicate the amount of stretch. *Consult the owner/service manual for proper tension.
   3. If you are working on a previously tensioned belt you will need to release the tension before attaching the gauges or calipers.
3. Gauges or Calipers unavailable
   1. Release the tension on the belt.
   2. Using a yard stick or tape measure, place two marks on the left and right edges of the belt and deck 36 inches apart (or 50 inches if you prefer).
   3. Adjust the left and right tensioning bolts until both sides measure 36 3/16 inches (or 50 1/4). This is equal to .5% of stretch.
   4. Test for proper tracking and tension, adjust if necessary.

Precor Error LS, Speed Sensor Signal Missing Probable Cause 1. Intermittent or open connection of the speed sensor (reed switch) wiring. 2. Reed switch is defective or has intermittent connection. 3. Drive motor brushes are bad. 4. Lower PCA is bad. Corrective Action

1. Inspect the speed sensor (reed switch) wiring for damage or poor connection to the lower PCA. Replace damaged wiring or reset connection as necessary.
2. Using an ohm meter, test the reed switch while rotating the drive pulley. The reed switch will close when the magnet passes in front of it.
3. Inspect the drive motor brushes and replace if necessary.
4. Test unit with a known good lower PCA. Replace lower PCA if necessary.

Precor Error Code LS

Precor Error 40, No Lift Motion Detected Probable Cause 1. Blown lift fuse in lower PCA. 2. Lift motor is physically jammed and not able to move. 3. Bad lower PCA. 4. Bad lift capacitor. 5. Bad lift motor winding. 6. Bad interconnect cable between upper and lower PCA. 7. Bad upper PCA. Corrective Action

1. Check the lift fuse from the lower PCA. Using an ohmmeter, the fuse should measure 1 ohm or less. If the reading is significantly high, replace the fuse. If the fuse is open, refer to steps 3 and 4 before continuing.
2. Disconnect the lift motor from the ramp (elliptical) or lift platform (treadmill). If the lift nut or lift tube is jammed against the motor housing, turn the lift tube or lift nut away from the motor housing. If the lift was jammed, refer to step 3 before continuing. Calibrate the lift motor per the proper procedure for the unit being serviced and reattach the lift motor to the ramp (elliptical) or lift platform (treadmill). NOTICE: You must find and repair the cause for the jammed lift. Only re-calibrating the lift motor will not solve the problem.
3. One of two modes can cause the lower PCA to fail. The lift switch could fail in an operated condition. If this happens the lift will move (either up or down) as soon as the unit powers up. The usual result is that the lift will be physically jammed as explained above, and probably also being cause for the lift fuse to blow. The lift switch could also fail in an open condition. If this happened, the lift would not operate in one direction. If either of these conditions occur the lower PCA needs replaced.
4. Most units have the lift capacitor mounted inside the lift motor, and others use external lift capacitors. This information applies to units with the external lift capacitors. If the lift capacitor is shorted the lift fuse blows. Check the capacitor for a short using an ohm meter. Disconnect the capacitor from the lift motor and test. A good capacitor reads in the millions of ohms. Replace the capacitor if the reading is significantly low. Capacitor can also fail in the open condition which would result with the lift motor trying to run but not having normal power. Test the capacitor by measuring AC voltage across it. A good capacitor will read AC peak voltage while an open capacitor reads AC RMS voltage.
5. When a lift motor winding is bad the lift will not operate in one or both directions depending upon the exact fault in the motor. Check the lift motor winding with an ohm meter. AC lift motors have a split winding (3 wires) and DC lift motors will have a single winding. Both windings must be checked on an AC lift motor. Normal winding readings could vary anywhere between 1 and 60 ohms, depending on the lift motor being tested. See the proper service manual for the motor being tested.
6. Test unit with a known good interconnect cable. Replace the interconnect cable if necessary.
7. Test unit with a known good upper PCA. Replace the lower PCA if necessary.

On C846 version 1 units, set the on/off switch in the "on" position. It will be necessary to start pedaling for the bicycle to "power up". For any other units, we recommend checking for any loose, crimped, or visually bad wires. Make sure the speed sensor on your bike is working. You can run a quick test by using a magnet to swipe in front of the sensor to see if it is sending signal to your console.

How to Tension Treadmill Walking Belt that Slips

Replacing a Treadmill Running Belt and Deck Following is a basic guideline of removing and replacing the running belt and deck on a treadmill. Due to different brands and designs of treadmills, the following should only be used as a guideline. If any of the information is not exact to the treadmill being serviced, refer to the service manual or call Sportsmith for further help. Tools Needed: Phillips Screwdriver, Set of Allen Wrenches, Set of Box End or Open Face Wrenches (Tools needed may vary depending on treadmill. )

1. Switch the Power off on the unit.
2. Next, unplug the unit from the wall.
3. Remove the finger guard retaining screws and carefully remove the finger guards from the deck at each end of the rear roller.
4. Loosen each rear roller bolt by 10 full turns. Then count the remaining turns necessary to remove the rear roller bolts. Remember to write down the number of turns needed to remove the bolts in each side for future reference.
5. Carefully remove the rear roller from the unit. Clean any wax or debris buildup from the roller and place it aside.
6. Raise the shroud and secure it with a bungee cord.
7. Work the drive belt off the motor pulley by hand turning the flywheel while pushing the belt aside.
8. Now remove the front roller retaining bolts.
9. Carefully remove the front roller from the unit. Clean off any wax or debris buildup and set it aside.
10. Loosen and remove the deck mounting hardware.
11. Move the deck toward the left side of the frame to free the deck from the right side. The deck will move down once the frame has been cleared.
12. Remove the deck and belt by raising the right side edge of the deck over the frame rail and sliding it to the right to remove.
13. When installing a new belt or deck it is important to note that a new belt and deck surface should always be installed together. Failure to adhere to this guideline will severely shorten the life of the newly installed parts. Some decks can be used on both sides. However, be sure that each side is only used once. Be sure to install the belt in the proper direction on the unit.
14. Install the belt and deck by first putting the belt on the deck, and then installing them from the right side as a unit.
15. Be sure the deck is lined up with the frame and push the deck to the left side.
16. Now carefully lower the right side of the deck to insert it into the frame rail and then push the deck to the right as far as possible.
17. Re-install deck mounting hardware. (Check with mfr. for proper torque during install process.)
18. Carefully place the front roller on the deck under the belt and push it forward into place, while placing the drive belt on the inside of the drive pulley.
19. Replace the front roller bolts. (Check with mfr. for proper torque during install process.)
20. Now spin the roller by hand while pushing the drive belt onto the pulley. Be sure to spin the roller several times to insure complete installation of the drive belt on the pulley.
21. Install the rear roller into unit. Carefully start each bolt and turn one to two threads to ensure no cross-threading has occurred.
22. Tighten each rear roller bolt the number of turns you kept earlier for reference.
23. Now, Plug in and power on the unit.
24. Carefully remove the bungee cord from the shroud and lower it back into place.
25. Start the unit at a very slow speed and check for proper belt alignment. Remember to start at the slowest speed possible and be ready to stop the unit quickly if needed.
26. If the belt is moving to right side of unit tighten the right roller bolt, If the belt is moving to the left side of the unit tighten the left roller bolt until the belt is tracking properly.
27. Caution: make very small adjustments such as 1/4 turns and then watch the belt for several moments before making another adjustment.
28. Once the belt is tracking properly walk on the unit at a slow speed and check for belt slippage on foot fall. If this is happening tighten each of the rear roller bolts equal turns until the slippage is no longer occurring. Caution: make very small adjustments such as ¼ turns and then watch the belt for several moments before making another adjustment.
29. Now use the unit at a jogging speed to check for belt travel or slippage.
30. If slippage still occurs make small equal adjustments (1/4 turns) to both sides of rear roller and re-test.
31. Install the finger guards once you have enough clearance from the rear roller.
32. Some manufacturers require wax or lube during the install process, please consult your owner's or service manual for further information regarding this.
