Precor 9.1 Mode 1 Treadmill Repair Parts Eprom - Answered Questions & Fixed issues


Precor Error 10, Line Frequency out of Acceptable Range Probable Cause 1. Treadmill is connected to a non-dedicated AC circuit
2. The AC hot and AC neutral wires are reversed on a 120VAC circuit.
3. The upper PCA has an incorrect jumper setting.
4. Fuse feeding the stepdown transformer is bad.
5. AC line frequency is incorrect.
6. AC line may be excessively noisy. Corrective Action
  1. Treadmill must be connected to a completely dedicated 20amp AC circuit. Both hot and neutral leads must be dedicated to the treadmill. If the circuit is shared with another piece of equipment, it can cause enough electrical noise to make the AC line frequency impossible to identify. The AC circuit for the treadmill must be re-configured as a completely dedicated 20amp circuit.
  2. Many line frequency detection systems observe the AC line frequency on the hot AC line. In the event of a reversed 120VAC circuit, the observation is taking place on the neutral (ground) part of the AC line. Many observing systems are not capable of detecting line frequency on the neutral line. First it must be determined if the reversal is in the AC wiring feeding the treadmill or in the internal wiring of the treadmill. The hot and neutral lines can be confirmed by measuring each in reference to AC (green wire) ground. The hot wire will read full line voltage (commonly 105 - 120VAC) and the neutral should read about 0VAC.
  3. The upper PCA's for some units had a jumper setting for use with SCR or PWM drive circuits. If the jumper was set on the upper PCA as PWM on an SCR unit, the Error 10 appears. Change the jumper setting to SCR to correct the problem.
  4. A pair of fuses were used on some treadmills (C944 PWM version 2 and C96x PWM version 2) that fed the stepdown transformer for the low voltage power supply on the lower PCA. The AC line frequency was observed on the output of one of the fuses. If the fuse blew, AC line frequency could not be detected even though the treadmill appeared normal under other circumstances.
  5. It is unlikely, however, the AC line frequency could be out of acceptable limits. This would more likely occor in countries were AC power systems may not be well developed and controlled. There is little that can be done to correct this issue. If the source frequency cannot be corrected, the only possibility would be replacing the treadmill with one that utilizes a PWM motor controller. PWM motor controllers do not depend on line frequency for speed control.
  6. At times the AC being fed into the distribution system is too electrically noisy to allow correct line frequency identification. This can be caused by other equipment within the AC distribution system creating the electrical noise. It can be difficult to identify the source of the electrical noise. There is little that can be done to correct this issue. The source needs to be located and removed or made electrically quiet. If this cannot be done, the only possibility would be replacing the treadmill with one that utilizes a PWM motor controller. PWM motor controllers do not depend on line frequency for speed control.

Precor Error E4, Incomplete Initialization Probable Cause Indicates that an incomplete upper PCA to lower PCA initialization occurred. When this error occurs, all lift motor and drive motor motion is ceased and the display will go blank except for the error displayed.
Corrective Action Run the initialization program. Caution: The treadmill's running belt will accelerate to the treadmill's maximum speed (12mph). DO NOT stand on the treadmill's running belt during the procedure.
  1. Set the on/off switch to the OFF position. Wait a minimum of 10 seconds to allow the internal power supply to discharge.
  2. Remove the safety key from the console and set the on/off switch to the ON position.
  3. Press INCLINE UP and SPEED DOWN keys together. While pressing these keys, replace the safety switch on the console. Continue holding the INCLINE UP and SPEED DOWN keys until the display goes blank. INIT will appear in the time window of the display. The EEPROM is now clear and reset. After a second, 1.25 will appear in the distance/calories window, 15.0 (the maximum incline) will appear in the incline window, and 12.0 (the maximum speed) will flash in the speed/pace window.
  4. Press QUICKSTART to begin the speed calibration process. Power bits will appear in the incline window, the target speed will appear in the time window and the actual speed will appear in the speed/pace window. At the beginning of the process, the target speed will be .5mph. The running belt will start. Once the actual speed reaches .5mph, the target speed will then change to 12mph and the running belt will accelerate until it reaches 12mph, then it will stop.
  5. When the running belt stops, the display will return to the user mode and the initialization process is complete.

Step 1:

1) test the fuse see the block diagram
2) replace the old batteries by new ones with the same type
3) tight the RIbonn cable FOR keypads, clean it.
4) Adjust the REED SWITCH, clean it, test for open or faulty, tight very WELL the connector, see the diagrama attached.
God bless you

disassemble as much as you can, and dry up all parts. hope that the electrical circuits/parts weren't damaged.

It might be the battery. A fully charged battery is required to move the ramp up and down. The battery is like a car battery, if you don't use it then it dies and might need to be replaced.

To clear the error log, press "QUICKSTART" for a minimum of four seconds while viewing the list. Prompts will appear on the display and let you know when the log has been deleted.

Are you sure the PSU is functioning? Check it with a multimeter set for DC Voltage. Compare what it is putting out to what the factory specs are.
