Precor Fitness equipment – Error code and troubleshooting - Error 74 to 87

ERROR 74, 75, 76, 77

Flat Belt Count, Mismatched console
Applies to
AMT12, all models
Issues Symptoms
The upper PCA and lower PCA compare the stride count record written on each EEPROM.
# Error 74: The lower PCA stride count is less than that of the upper PCA, and the upper PCA is less than 30,000 strides.
# Error 75: The lower PCA stride count is less than that of the upper PCA, and the lower PCA is less than 30,000 strides.
# Error 76: The lower PCA stride count is greater than that of the upper PCA, and the upper PCA is greater than 30,000 strides.
# Error 77: The upper PCA stride count is greater than that of the lower PCA, and the lower PCA is greater than 30,000 strides.
The events will be recorded to the error log during the workout summary and the lower PCA stride count record is written to the upper PCA EEPROM.
The most likely cause of these errors is that upper PCA or lower PCA was replaced during troubleshooting, utilizing the related board from an adjoining unit.
Troubleshooting steps
In general, no action is needed. This is an event that has been recorded to the error log.
Troubleshooting Note:
If you are swapping a PCA to perform troubleshooting, note the process below to prevent the stride count odometer from being prematurely overwritten.
# When you stop pedaling the AMT, the AMT will pause for 20 seconds, and then give a 10 second workout summary (which is when the records are written between the PCA’s). After the PCA is replaced and testing the AMT is complete you will need to unplug the data cable from either PCA within the 20 second pause period to prevent the summary from happening. If the AMT is prevented from going into the summary, the stride count will not be overwritten.
# When testing is complete make sure that each PCA board is replaced in the original unit from which it was removed. The only exception to this would be if you find a bad board that needs to be replaced.
# All of these functions will place a code in the error log, and they should be cleared before returning the unit to use.

ERROR 78, 79

Flat Belt Replacement
Applies to
AMT 12
Issue Symptom
The AMT12 flat belt system has a predetermined life span of 100,000,000 (100M) strides. The AMT12 maintains a stride count independent from the overall machine stride count. When this stride count reaches 90,000,000 (90M) strides, error 78 is recorded in the error log and displays a message, alerting that the flat belts need to be replaced soon. Normal workout operation is still available. When the stride count reaches 100M strides error 79 is recorded in the error log and displays a message, indicating that the flat belts must be replaced. If this occurs during a workout the user will be able to continue the workout until ended. No further workouts will be allowed until the stride count is reset in the console after the belts have been replaced.
Troubleshooting steps
1. Replace all four flat belts.
2. Reset the flat belt stride odometer.

ERROR 80, 81, 82, 83

Phase A or B Missing / Incline Control
Applies to
P30 Console, all products
Issue Symptoms
The main symptoms for these errors are lack of control for incline and speed (TRM) or resistance and crossramp (EFX, AMT). These errors will occur upon “lack of” or broken hardware communication. The sensors communicate through an 8-pin connection. Pins 1-3 are incline controls; pins 6-8 are drive (speed or resistance)
controls.
# Error 80 - Incline (or crossramp) will stop at current incline. Error 80 is displayed when there is a missing incline signal on pins 1 or 2.
# Error 81 - Incline (or crossramp) will stop at current incline. Error 81 is displayed when there is a missing incline signal on pin 3
# Error 82 - Speed will decrease at 0.1mph per key press until belt stops. Error 82 is displayed when there is a missing drive signal on pins 6 or 7
# Error 83 - Speed will remain at current speed. Error 83 is displayed when there is a missing drive signal on pin 8.
The most likely causes for these errors are a loose or disconnected connector to the upper PCA, damaged cables, or a faulty machine control.
Troubleshooting steps
1. Check the Error log for multiple occurrences of the error with the same odometer reading. Clear the error log, and cycle power to the machine.
2. Open the console and check the connectors. Ensure that they are securely connected to both the upper PCA and to the machine control.
3. Check the cable for visual damage; use an ohmmeter to verify continuity on each line. Replace both the cable and machine control if a fault is found.
4. Inspect the machine control for corrosion or damage, and replace both the machine control and cable if any damage is found.
5. Review the software version of the P30. If the user states the issue is related to the machine controls not working as designed, the P30 software may need to be updated in addition to the replacement of the machine control and cable assemblies.

ERROR 85

No Dynamic Brake Resistor Detected
Applies to
TRM800.v2
Issue Symptoms
The dynamic brake resistor (DBR) is designed to absorb the excessive current produced by the drive motor turning faster than it is being driven. When the Machine Controller boots up, it checks for the resistor to be plugged in. If it detects an open an error 85 will be displayed. It will only be displayed briefly when power is applied. The most probable cause for this is the DBR not being plugged in, or it is open due to overheating or a broken cable.
Troubleshooting steps
1. Visually determine if the DBR is connected to the MC.
2. Use a multimeter and measure the DBR. It should read 100 ohms. If this is significantly higher than 100 ohms replace the resistor.

ERROR  86,87

Console Mismatch
Applies to
TRM800.v2 P10, P30
Issue Symptoms
The P10 and P30 for the TRM800.v2 require different software versions than the TRM800.v1 for communicating with the Machine Controller. Installing a console with mismatched software between the console and MC will cause an error to be displayed.
# Error 86 occurs when TRM800.v1 console software is connected to TRM800.v2 MC software.
# Error 87 occurs when TRM800.v2 console software is connected to TRM800.v1 MC software.
Troubleshooting steps
Update the software in the console to the correct version.

ERROR MESSAGES
NOVRAM - DGA3J:

Px values "Init"(flashes on board and beeps) on power up. Px values stored in NOVRAM are outside valid ranges or the checksum is invalid. The system checks for a valid P6 configuration. It writes the default values with respect to P6, if valid. If not, it writes default values to the NOVRAM based on a "4" (T9350) configuration. No user interface necessary - occurs on power up. P6 value may need to be recalibrated depending on model: This console will reconfigure itself for a T9350.
NOVRAM - DGA3J:

User program values "UCLr" (flashes on board and beeps) on power up. Time, speed, and elevation values stored in NOVRAM are outside valid ranges or the checksum is invalid. The system clears the user program values. No user interface necessary - occurs on power up. If "init" occurs, "UCLr" also occurs afterwards, but not vice versa. 

NOVRAM - DGB1J:

Same NOVRAM error as the DGA3J except the treadmill will reconfigure itself for a T9600HRT. P6 value may need to be recalibrated depending on the model: NOVRAM - DGB1J: Same NOVRAM error as the DGA3J

Precor Fitness equipment – Error code and troubleshooting - Error 50 to 73

Error 50
Too Much Brake (Magnet) Current
Applies to
Consumer EFX, AMT, U/RBK
Issue Symptoms
This error is associated with eddy current EFX’s, AMT's, Climbers and Bikes. The resistance (brake) control system constantly monitors the amount of current being demanded by the eddy current magnet. Error 50 indicates that the amount of current being demanded by the eddy current magnet is excessive. The most common cause of this error is shorted or damaged wiring between the lower PCA and the eddy current magnet. While possible but lease likely, this can be caused when the eddy current magnet is bad or the lower PCA is bad.
Troubleshooting steps
1. Carefully check the eddy current wiring and connections, ensuring that the wires are not shorted together or shorted to the frame. Repair or replace the damaged wiring as appropriate.
2. Unplug the eddy current cable connection from the lower PCA. Pedal the unit and increase the resistance level, if the error is still displayed, replace the lower PCA. If the error is not displayed, replace the eddy
 

Error 60, 61
Auto Stop Not Working/Present
Applies to
These errors are associated with the TRMv1 Treadmill
NOTE: These errors will not be present if the magnet on the deck is missing or misaligned. These errors will only indicate an electrical problem with the sensor. Failing to move or correctly align/gap the magnet when the deck is flipped, or moved to a new deck when a previously flipped deck is replaced, will cause the Auto Stop function to engage after 90 seconds of use, with a 10 second countdown following.
Issue Symptoms
Error 60 indicates the Auto Stop feature has stopped functioning during a workout. If the error is detected while a workout is in progress, the treadmill will operate normally until the workout has ended. At the end of theworkout, the error will lock out the next user, displaying "Temporarily Out of Order, Please Use another treadmill" on the P80 console and "PLEASE USE ANOTHER TREADMILL" on the P30 and P10 consoles. When this error occurs error 60 will be recorded in the error log of the console. The most likely cause of error 60 is a poor or missing connection between the Auto Stop sensor and the cable connecting the sensor to the console. A damaged or faulty Auto Stop sensor may also cause this problem. Least likely but possible is a failure in the upper PCA/Console.
Error 61 indicates the Auto Stop sensor is not detected. If the error is detected the user will be locked out, displaying "Temporarily Out of Order, Please Use another treadmill" on the P80 console and "PLEASE USE ANOTHER TREADMILL" on the P30 and P20 consoles. When this error occurs error 61 will be recorded in the error log of the console. The most likely cause of error 61 is a broken or disconnected cable between the sensor and the console. Less likely but possible is a missing or faulty sensor.

Troubleshooting steps
1. Check that the Auto Stop cable connectors are secure at the sensor and console. Visually verify the Auto Stop hardware components are installed onto the treadmill frame. If the Auto Stop hardware is notpresent contact Precor Customer Support. Check that the Auto Stop cable connectors are secure at the sensor and console. Visually inspect the Auto Stop sensor for physical damage and correct installation. Replace if appropriate.
2. Access the diagnostic system tests, and select the Auto Stop test. If the feature is enabled the P80 Auto Stop sensor test will count the number of times the magnet crosses the sensor. The P30 and P20 consoleswill display "USER DETECTED" if motion is detected from the running deck or "NO USER DETECTED" if no motion is detected from the running deck. If the Auto Stop test in the P80 did not count steps or if the P30 and P20 consoles displayed "NO USER DETECTED", disconnect the Auto Stop cable from the Auto Stop sensor and check for 5 vdc between the red and black wire. If 5 vdc is present replace the Auto Stop sensor. If not present, continue with the next test.

3. Check for 5 vdc at the upper PCA or console. Disconnect the Auto Stop cable connector from the upper PCA or console and measure the voltage from the console. If 5 vdc is not present replace the upper PCA or console. If 5 vdc is present then replace the Auto Stop cable.

Error 62
Vertical Sensor Failure
Applies to
AMT 12
Issue Symptoms
Error 62 will occur when the vertical stride is not detected. The most likely cause of this will be a faulty, broken or poor cable connection at the lower PCA. A missing or reversed magnet on the crank arm is also a possibility, as is a defective sensor. Least likely but possible is a fault on the lower PCA.
Troubleshooting steps:
1. Check to ensure vertical sensor cable connector is secure on lower PCA, and that the cable is intact, that it has not been compromised.
2. Verify the magnet is present in the crank arm, and is correctly installed. The sensor is polarity sensitive, and an incorrectly installed magnet will cause this error. To test it, remove the magnet from the crankarm, and while in the Stride Sensor test move the magnet back and forth past the sensor, if the polarity is correct you will see counts recorded.
3. If the previous test does not show a count (regardless of polarity) eplace the vertical sensor with a known good vertical sensor. Retest.

4. Substitute the lower PCA with a known good lower PCA.

Error 70-79
Flat Belt Count Error Overview
Applies to
AMT12, all models
Issue Symptoms
These errors have to do with the flat belt count of the AMT12. The AMT12 utilizes a flat belt system to provide fluid movement and support to the stairarms. It is critical that the flat belts are replaced at a defined stride count.
To ensure the stride count is maintained throughout the life of the AMT12, the stride count is stored on both the lower PCA and the upper PCA.If either PCA is replaced, the stride count will be written to the new board, depending on certain criteria. Different conditions will cause an error to be logged. In most cases errors 70 to 77 will be for informational purposes, and will not affect the operation of the AMT. Errors 78 and 79 will indicate that belt replacement is imminent or necessary. The PCA’s will compare software versions and stride counts, and an appropriate error will be generated as an indicator of the condition. These error scan be used to determine if used or new PCA’s were installed.

Error 70, 71, 72, 73
Flat Belt Count/Software Mismatches
Applies to
AMT12, all models
Issues Symptoms
When power is applied to the upper PCA and lower PCA, the stride count written on each of the EEPOMs will be compared to each other and to a set of preset stride conditions. If the stride count written on the EEPOM's do not match or meet a preset stride count condition, a error will be written to the error log or displayed to the user at the end of the workout summary.
# Error 70: Lower PCA not read. The upper PCA EEPOM cannot detect the stride count written on the lower PCA. This error is only reported to the error log. This is usually caused by a lower PCA with no software installed.
# Error 71: Lower PCA. The upper PCA has detected a lower PCA that does not have a stride count written to the lower PCA EEPROM. This is not an error and is used for tracking only. For reference it will be reported to the error log.
# Error 72: Lower PCA version not known. A version mismatch is detected between the EEPROMs of the upper PCA and the lower PCA. When the upper PCA reads the data from the lower PCA’s EEPROM, andthe internal version isn’t correct, the upper PCA logs error 72. The upper PCA will then attempt to write the correct version number to the lower PCA. If the correct version can be successfully written to thelower PCA’s EEPROM, then this error probably won’t be seen again. If the upper PCA version number cannot be successfully written to the lower PCA, then numerous errors will be logged with different odometer values. The occurrence of this error would be rare and if it did occur, the normal operation of the AMT12 would not be effected.
# Error 73: Lower PCA record bad. A byte size error is detected between the EEPROMs of the upper PCA and the lower PCA. When the upper PCA reads the data from the lower PCA’s EEPROM, and the byte sizeisn’t correct, the upper PCA logs error 73. The upper PCA will then attempt to write the correct byte size to the lower PCA. If the correct byte size can be written to the lower PCA’s EEPROM, then this errorprobably won’t be seen again. If the upper PCA byte size cannot be successfully written to the lower PCA, then numerous errors will be logged with different odometer values. The occurrence of this error would be rare and if it did occur, the normal operation of the AMT12 would not be effected.
Troubleshooting steps
1. Error 70: Replace lower PCA with a known good lower PCA.
2. Error 71: None, this is for informational purposes only.
3. Errors 72 and 73: These errors will not affect the operation of the AMT12 and the error would only be recorded in the error log. Replacing the lower PCA would only resolve the repeated recordings of theerror in the error log.

Precor Fitness equipment – Error code and troubleshooting

Error 35, 36
Excessive AC Input Current
Applies to
TRM 800.v2
Issue Symptoms
Error 35: This error monitors the instantaneous input current to the treadmill. If the input current should spike above 65 amps, an Error 35 will be displayed. The most likely cause of this error will be a catastrophic failure internally to the MC.
Error 36: This error monitors the average input current to the treadmill. If the MC detects current in excess of 20 amps for a sustained period an error 36 is displayed and the treadmill shuts down. The most likely cause of this is a worn deck and belt. It is possible that this error could be caused by a combination of a worn deck/belt and the DB Resistor being stuck ON. Low line voltage can cause error 36; however this usually causes an error 16, so check for that error in the log. If the error 36 occurs when the treadmill is fairly new, and the facility has not had other treadmills plugged in previously, it is possible that the wiring to the outlet is not of sufficient gauge to handle the current required.
Troubleshooting steps Error 35
If error 35 is persistent, replace the MC.
Troubleshooting steps Error 36
1. Check the belt rating (120VAC only) and current draw of the treadmill, replace the belt and deck as necessary
2. Monitor the minimum line voltage as follows:
a. With the TRM at the Welcome banner
b. With a runner at 6MPH
c. With the TRM at the Welcome banner, and a runner at 6MPH on an adjoining tread
3. If fluctuations of greater than 15% are observed between the banner case (a.) and the runner @6MPH case (b.), or if fluctuations of 5V or more are seen when running on the adjoining TRM, request an evaluation of the distribution wiring.

Error 37
E-STOP Upper PCA/Lower PCA Mismatch
Applies to
TRM800.v2, TRM2XX
Issue Symptoms
The error 37 may occur after an E-STOP event. If the E-STOP event is not successfully cleared in the lower PCA and the upper display believes the E-STOP has been cleared, a error 37 will occur. Possible causes include pulling and resetting the E-STOP twice within the 10 second time-out period, pulling the E-STOP, turning off the treadmill, turning the treadmill back on, and then starting a course, or pulling the E-STOP, turning off the treadmill, reset the E-STOP, turning the treadmill back on, and then starting a course. Also possible is a break in the E-STOP line, or a loose cable connection.
Troubleshooting steps:
1. Verify the connectors are seated properly.
2. Verify Dielectric grease has been applied to both connectors.
3. Run the treadmill and move the communications cable attempting to duplicate the error. If it reproduces, change out the cable.
4. If this error is persistent and none of the above corrects the problem, install a new console.
5.If the console does not correct the problem, change the MC.
Recommended Additional Action:
Add Dielectric grease, to both connectors, recommended for all products regardless of age.

Error 40
No Lift Motion Detected
Applies to
All Treadmills and EFX, AMT12
Issue Symptoms
Error indicates that the incline (lift) system on either a treadmill, EFX or AMT12 has been instructed to start moving and no lift motion has been detected by the lift position monitoring system. Most likely causes are a blown lift fuse on the lower PCA or the lift motor is physically jammed and unable to move. On the EFX and the AMT12 a fully dead battery can also cause this error. While unlikely but possible, a faulty lift motor capacitor or winding will prevent movement.
Troubleshooting steps:
1. Remove power from the unit and remove the lift fuse from the lower PCA. Measure the fuse with an ohmmeter, if the reading is higher than very near zero, replace the fuse.
2. Disconnect the lift motor from the lift platform (treadmill, AMT12) or ramp (EFX). If the lift tube or lift nut is jammed against the motor housing, rotate the lift nut or lift tube away from the motor housing.Calibrate and install the lift motor per the appropriate service manual procedure.
3. With a voltmeter reading AC volts, measure between the black wire of the lift motor connector and the hot lead of the line filter. You should read line voltage. Enter Diagnostics, Machine Test, Incline Test, and operate the lift in the up direction. You should read approximately 200VAC (120V Units) or 300V (240V Units). If this value is significantly low the capacitor is failing, requiring lift motor replacement.
4. If a lift motor winding is bad the lift will not operate in one or both directions depending on the exact fault in the motor. The lift motor winding may be checked with an ohmmeter. A.C lift motors will have a splitwinding (3 wires). D.C lift motors will have a single winding (2 wires). On A.C motors both windings must be checked. Depending on the lift motor being tested, normal winding readings could vary anywherebetween 1 and 60 ohms. Refer to the appropriate service manual for the motor being tested.

Error 42
Lift Position Out Of Range
Applies to
All Treadmills and EFX, AMT12
Issue Symptoms
The software on the lower PCA is expecting that the A/D value from the lift potentiometer is within a certain range, low to high. If the A/D value goes outside this range, an Error 42 will be displayed. The most likely cause of this error is the motor moving further than it should, or jamming against the housing. A loose connector or a damaged potentiometer inside the motor assembly will also cause this error.
Troubleshooting steps:
1. If the lift motor has drifted too low, disconnect the motor from the lift assembly and adjust the jack screw until the motor is in range. Perform the appropriate lift motor calibration procedure. If the motorcontinues to drift low, replace the motor.
2. Inspect the lift motor connector, verifying the pins are secure in the connector. Attach the connector to the lower PCA and ensure that it is locked into the header.
3. Enter Diagnostics, Machine Test, Incline or Crossramp test. Run the lift all the way extended and back to minimum. The A/D number should climb and decrease smoothly during the test. If not, replace the liftmotor.
4. While in the Incline or Crossramp test scroll to see Glitches, and run the lift to both extremes. Glitches are anomalies recorded by the lower board during lift movement, indicating a possible or existing problemwith the internal potentiometer or the gearing that turns it. Very few if any glitches should be recorded. If greater than 50 glitches are recorded during a full movement to either extreme, replacement of the liftmotor is necessary.

Error 44
Un-commanded Lift Motion
Applies to
All machines with a lift actuator
Issue Symptoms
The lift control system has detected that the lift is in motion without a lift command having been issued. This can happen in one of two ways: either the lift drive circuit has failed in a turned on condition or the lift position sensor (lift position potentiometer or revolution sensor) is sending an erroneous signal to the lift control circuit. This is most often caused by a poor or intermittent connection of the lift motor potentiometer, or the potentiometer itself is defective. Less likely but possible is a defective lower PCA.
Troubleshooting steps:
1. Verify all wiring and connections associated with the lift motor assembly. Repair or replace wiring or connections as appropriate.
2. Operate the lift in the diagnostics while monitoring the lift position A/D number being displayed. If the reading is erratic and makes large changes in readings the lift position potentiometer is probably bad.
Replace the lift motor assembly.
3. If there is actual lift motion without a manual or program control lift command having been issued, replace the lower PCA.

Error 45
Lift Moving In The Wrong Direction
Applies to
All machines with a lift actuator
Issue Symptoms
The lift control system has detected that the lift is moving in the opposite direction of the issued lift command. This error would typically happen when the lift was already in motion (typically downward) when a lift command in the opposite direction (lift up) was issued. Some motors exhibited a very long turnaround time and the lift motor would still be moving in the original direction (downward) while the control system was attempting to move the lift in the opposite direction. Less likely but also possible would be a defective motor controller.
Troubleshooting steps:
1. Check that the MC is properly controlling the lift motor. Measure between the line filter hot output and the red wire of the lift motor connector while pressing the up button in Diagnostics. You should see line voltage when the motor is not being driven, and 0Vac when it is being driven. Repeat the test with the black wire of the connector and the downward drive. If the MC is not switching properly, replace the MC.
2. If the error 45 condition is persistent and the voltages from the controller are correct, replace the lift motor.

Error 46
Low Battery Voltage
Applies to
All self-powered units
Issue Symptoms
The operating system has a battery monitoring system. If the battery voltage falls below 11 Vdc when stride height movement is initiated (AMT12) or the battery voltage falls below 10 Vdc after the ramp movement has been initiated (EFX), ramp movement will be stopped and the message ERROR 46 will be displayed. Stride Height motion will not be enabled until such time as the battery voltage exceeds the above limits. The battery voltage must be raised to correct this condition either by battery charging or battery replacement. This is strictly a battery problem and not an incline system or incline motor problem. Possible causes include an open 10A slow blow fuse (AMT12 only) on the battery terminal, faulty or poor connection on the battery or lower PCA, or a depleted battery.
Note: While an occurrence of the error is possible, this error is rarely reported on self-powered bikes and climbers.
Troubleshooting steps:
1. (AMT12) Remove the lift fuse from the in-line fuse holder on the positive battery cable. Measure the fuse with an ohmmeter, the fuse should read approximately 1 ohm or less. If the ohmmeter reading is significantly high, replace the fuse.
2. Check battery cable connector for shorts or poor connections.
3 Enter the diagnostic program per procedure, P80 Settings or Accessing the P30 Diagnostic Software. Using the diagnostic program allows you to test the incline system without continuously pedaling the unit if you have an external power supply. Otherwise, you will need to continue to pedal the unit. Connect a DC volt meter to the J3 connector on the lower PCA as follows: voltmeter common lead to terminal 3 (black wire) and voltmeter "hot" lead to terminal 2 (red wire). Using the STRIDE HEIGHT. The voltmeter should read +12 Vdc approximately when the incline is instructed to move upward and -12 Vdc approximately when the incline is instructed to move downward. If the either voltage measurement is significantly low, replace the battery.
