20 Most Recent Vision Fitness T9550 Folding Treadmill Questions & Answers

hi. i think the problem is with your touch switch panel. regards, nuwan

Step 1:

please see this test and fix it. God bless you

The Steps for Newer Style Console Calibration:

1. Locate the calibration area on the rear or underside of the console (a hole, near the console's center, that goes through to the electronics board. (This hole should not have a screw in it.)

2. Insert a pencil (eraser end), into the hole and feel around for the cal button (will click when pressed).

3. Press the button 2 times (with the pencil eraser). The first click should show CL11 in the console, the second click should show CL21.

4. If the process was done correctly, and CL21 appears in the console, you are in "calibration mode." The next few steps consists of pressing buttons on the console and observing settings. This will not require any other tools.

5. Press ENTER. CL22 should display in the TIME window and (??) in the SPEED window.

6. Press ENTER. CL23 should display in the TIME window and (??) in the SPEED window.

7. Press ENTER. CL24 should display in the TIME window and (??) in the SPEED window.

8. Press ENTER. CL25 should display in the TIME window and (??) in the SPEED window.

9. Press ENTER. CL26 should display in the TIME window. You should then see the letter "E."

10. Press ENTER. You should see "SS" or "55" in the console.

11. Push the STOP/START button. For safety, at this point, you should step off, or be off, the treadmill.

12. Push the ENTER button. The walking belt should start to move, accelerate to maximum speed, then stop on its own.

13. When the belt stops, the incline should self test by raising to its highest incline position, then lowering back down to its lowest position.

14. Once the incline test is complete, push the POWER button 2 times. The unit should shut off and the console should go completely blank. If this happens, the treadmill is done calibrating and is ready for use.

15. If the letter "F" appears in the SPEED or INCLINE window when the power button is pressed 2 times, the treadmill is indicating a failure somewhere either in the SPEED or INCLINE (depending on the window the "F" appeared in).

Step 2:

The SCR lower board is designed with diagnostic LED lights. The LED's are color coded according to

their specific function. Green indicates a properly operating treadmill; the green lights should always

be ON when power is supplied to the treadmill. Yellow indicates a treadmill function. Red indicates a

treadmill malfunction. Here is a list of each LED and what it signifies:

MOTOR (yellow) - The MOTOR LED illuminates when dc (direct current) voltage is sent to the drive

motor. The LED gets brighter when the dc output is increased.

RLC (yellow) - The RLC (R = Reactance / L = Inductance / C = Capacitance) LED illuminates when

the filtering system is properly working. The filtering system includes the capacitor and filter choke. If

there is a short in either component then the RLC light will not come on.

DN & UP (yellow) - The DN and UP LED lights tell us if the elevation DN and UP relays are

functioning properly. When the LED lights, it tells us that the relay has energized and is sending high

voltage (110vac or 220vac) to the elevation motor.

AC PWR (green) - The AC PWR (Alternating Current Power) illuminates when AC line voltage is

delivered to the treadmill. It then passes through the in-line fuse (110)/s(220) and lights the AC PWR

LED.

+12V (green) - When the proper AC voltage is delivered to the treadmill, passes through the in-line

fuse/s, through the full wave bridge rectifier (changes AC to DC), through the transformer (steps down

This the board LED, who control the DC to +12vdc) then the +12V LED lights.signal for Main Motor+Elevation Motor. You must see, the LED DN+ UP( both will be Lit) in any position down or Up.

2) The RELAY board is designed with diagnostic LED lights. The LED's are color coded according to

their specific function. Green indicates a properly operating treadmill; the green lights should always

be ON when power is supplied to the treadmill. Yellow indicates a treadmill function. Red indicates a

treadmill malfunction. Here is a list of each LED and what it signifies:

AC PWR (green) - The AC PWR (Alternating Current Power) illuminates when AC line voltage is

delivered to the treadmill. It then passes through the in-line fuse (110)/s(220) and lights the AC PWR

LED.

VDC (green) - The VDC LED will light when it receives DC voltage from the DC power supply.

DN & UP (yellow) - The DN and UP LED lights tell us if the elevation DN and UP relays are

functioning properly. When the LED lights, it tells us that the relay has energized and is sending high

voltage (110vac or 220vac) to the elevation motor.

UPSW (green) - This LED will illuminate when the low voltage dc is delivered from the upper display

board to the elevation UP relay. This low voltage dc is what energizes the coil of the relay.

DNSW (green) - This LED will illuminate when the low voltage dc is delivered from the upper display

board to the elevation DOWN relay. This low voltage dc is what energizes the coil of the relay.

BELTSW (green) - This LED will illuminate when the low voltage dc is delivered from the upper

display board to the belt (motor start) relay. This low voltage dc is what energizes the coil of the relay.

SPD (yellow) - The SPD LED flashes on and off (relative to speed) when the speed sensor is

operating properly.

PWM (yellow) - This LED will light when the upper board is sending a speed signal to the PWM.

Both the PWM LED and BELTSW LED must be lit for belt movement.Finally this this Relay Board, the Each Led will be Lit, for any Relai control for DN down, or UP for elevation Motor. You must clean contact of the Relay with Special Spray(Radio Schack).With this you must fix it.

Step 3:

please lube the elevation motor, shaft, and gear, and adjust the POT for RPM, and see what happen. see the diagram + block diagram attached for troubleshooting and fix it. God bless you

Good Luck

It sound like either the function pad ( more likely the problem ) or the upper electronics have failed. You will need to call Vision Fitness customer support @ 1-800-335-4348

Question edited for clarity and toss in some CAPS. It is sold as an entry level fitness bike, but try the troubleshooting or contact them direct.

1)probably a faulty speed sensor 2) the speed sensor is not plugged in properly.3) possibly a faulty motor test for 115 vca without load 4) control board or lower board for measure 115 vca and +5vca 5) Run the calibration sofware for easy diagnotic see the diagram attached.6) Test the transformer for primARY VOLtage and secondary voltage. see the TIP.

First thing to do with these folding vision fitness treadmills is REPLACE THE MAINS SUPPLY CABLE They were supplied with very poor quality cable that cause issues like juddering stopping and speed fluctuations.

My guess is the drive belt has come off. Open the plastics up slightly and look in with a torch.
