Eletric treadmill Speed Sensor Adjustment

hi margaret.
see if this link helps you out.
How do set the alarm on my Doogee X5 MAX mobile phone Google Search

Hi There, Speed sensor too far from front roller or defective? Lower control board not reaching target "set-speed" when compared to roller feedback may be a failing lower control board. Good Luck

Hire a professionals, many mishaps and damage to electronics to the machine can occur during a mobe.

1) Faulty sensor speed try to adjust it face to face magneto motor
2)Sensor speed try to tight the connector very well.
3) Replace if neceesary.4) Main motor faulty or burn. Test 115vac for input measure without load fore easy running.
5) Test the main motor controller board for 115vac input and output for +5VCD,
6) Adjust the deck bel for 2-3" for lift max.
7)Lubricate the deck bel.
8) Test the transformer for input and secondary voltage.
See the block diagram for illustration how the main motor controller has 90% aprox of function of any treadmills.

sincerely. Merry Christmas.

hi,
There are two possibilities for this problem
1. Check the speed sensor on near the motor pulley. Remove the sensor and clean it and re-fix it. then make a try. if problem remains then
2. The motor speed controller is faulty. There is an IGBT for controlling the motor speed. If it get shorted the motor will run it its high speed.

Be sure before opening the treadmill remove the power.
ok

Remove the console from the treadmill and remove the back
remove and replace the ribbon cables that run from the keypads to the control board (they are flat plastic strips that push into the board).
remove and replace all the connections on the console
reattach the console and calibrate by doing the following:
1. With the key off press the speed + and stop buttons at the same time and hold
2. place the key on and release the buttons
3. press the stop key once
4. press the speed up til it reaches 85
5. if your max speed is 10 mph then it should read about 9.8-10.2

If the keys will not work then the console is bad and would need replaced.

Go to iconservice.com click on manual input manufacturer and model name 1000.
Try this calibration procedure:
1) Press the Stop and the Speed Up keys down while inserting the safety key. If this doesn’t work, click on the help topic entitled “Alternate Calibration Codes” for key sequence instructions to enter calibration.
2) Press the Stop key one time. The Time window should read EP:2P. Some newer models may also say FP, Pass, or the like. This means that it passes the EPROM test.
3) Press either incline key and the incline will calibrate automatically.
4) BE CAREFUL, THE TREADMILL WILL RUN AT FULL SPEED IN THIS NEXT MODE! DO NOT STAND ON THE WALKING BELT. Press the Speed Up key and hold it down until 85 is shown in the Distance window (some models may show the 85 number in another window).
5) If the top speed of the treadmill does not match the displayed speed on the computer console, adjust the max speed potentiometer (pot) on the motor control board. This is the board that the red and black motor wires connect directly into in the motor area. The Max Speed pot is clearly labeled.
6) The max speed potentiometer is a small square with a mobile center and is located in one corner of the board and is labeled MAX SPD. It is near the harness that carries the speed signal labeled H,W,L. Using a small insulated screwdriver adjust this potentiometer clockwise to speed up and counter-clockwise to slow down the max speed of the treadmill. A tiny turn of this potentiometer will make a big difference in speed so be careful when making adjustments.
7) It is not important to get the speed set exactly at the max speed of the treadmill but do make sure to get the speed within .2 MPH of the max speed of the treadmill. For instance if the max speed of the treadmill is 10 MPH, make sure to have the speed set between 9.8 MPH and 10.2 MPH. Some models have a 12 MPH top speed, so please check your manual if you aren’t sure.
8) THIS IS A VERY IMPORTANT STEP BECAUSE YOU WILL GET AN ERROR MESSAGE IF THIS STEP IS SKIPPED.After completing calibration of the speed, press the Speed Down key. The treadmill will automatically return to 0 MPH. Please allow the unit to stop completely before continuing.
9) THIS IS A VERY IMPORTANT STEP BECAUSE YOU WILL GET AN ERROR MESSAGE IF THIS STEP IS SKIPPED.Press the Stop key once and remove the safety key.
