My matrix t3x treadmill is not calibrating,it's says calibration fail?what could be the problem .its an AC motor treadmill

Hi There, No "rumble" sounds from the motor? All seems normal but won't calibrate? Is there a speed sensor mounted to the rear of that AC motor? Little black box looking thing that watches an encoder wheel to measure speeds? If so, Matrix had a sensor mounted here for a few years on AC driven treads, with 3 wires coming from it and plugs into that lower board. If the large "slots" in that encoder wheel get dust in them, the controller will loose speed feedback pulses required for regulation. If that is all clean, you may not believe this, but there was a period of maybe 8 months where inside that little black box, one of those 3 wires were not soldered correctly and is loose, touching a nearby wire inside, or open all together, causing that controller to miss feedback pulses. That sensor must be viable to calibrate that machine. If you power off, then pull that speed sensor from the main lower board, power back up, the lower unit will default to no-feedback(open-loop mode) mode and may run very near normal speeds. Power down and re-install that wire and does the tread work normally when not calibrating? Lastly, if the unit has had a lot of use, that lower board could have degraded capacitors on it that decay over time and become a bit lazy, not allowing enough drive current for the motor to calibrate at high speeds, and failing the cal routine? Is that lower maybe marked ASM-ACD3x or similar?You can email me at jatinahATrocketmailDOTcom for more help if needed. Good Luck!

Fuel injector calibration

Injector calibration simply cannot be done without expensive and complicated test equipment. Fuel flow and spray patterns MUST be tested and adjusted using this equipment. Trying to do it without it is folly. Look in your local phone book to see who is in the business.

I have a vision T9500 treadmill. My husband was recalibrating and it got stuck in the highest position and is displaying E5 in the window. Any ideas how to get it down?

Try AUTO-CALIBRATION first. For that do the following.

With the safety key in place, turn the treadmill ON . Press and hold SELECT. Now you can perform auto-calibration by pressing START.

(The treadmill will run through minimum and maximum speed and elevation. This will take 3 to 5 minutes. Let the treadmill perform this complete function. "END" will appear when auto-calibration is complete. When auto-calibration is complete, it will take about 30 seconds for the treadmill to reboot and return to the start-up screen)

If it doesn't help then the motor control module is faulty. You have to replace or repair the motor control module.
