Dismantle a Vision Fitness - Elite T9450 HRT Folding Treadmill

SOURCE: Vision Fitness T9450 Treadmill error code "E4."

Hi,

E4 means
- Elevation parameters out of range
- Recalibrate it

If you want to calibrate it see the manual page no 5.

Dear Sir:

Hello I hope that everything is o.k

Now I will help you, only thing is you need to know how to handle the DVOM(digital Voltimeter)


To use these instructions, you need to have a familiarity with electricity and a working knowledge of a voltage multimeter. With all of
these tests, USE EXTREME CAUTION!!! Never let the voltage ground directly to any part of the treadmill or your leads ground while you
are testing voltage.
To begin, set your volt meter to AC volts. We are going to trace the power from the wall outlet through the
treadmill to see where it ends.
With the treadmill unplugged, test the wall outlet. You should have from 115 to 125 VAC. Optimally, you will
have at least 120 VAC.
Follow the power leads from the power cord to the lead ends. With the treadmill unplugged, connect your
meter to the lead ends. Plug the treadmill in and check your reading. It should be the same as your reading
from the wall outlet.
Continue this process with the electrical system, following the leads, as they pass through, breakers, fuses,
and the like.
Where the power flow ends is where your problem is. Sometimes it will be in a bad connection, sometimes
it will be in a shorted breaker or blown fuse, at times it may be as simple as a safety switch not working
properly, or it may be a major problem with a component.
In some cases, components work in tandem (i.e.- a controller may need a signal from the console
computer to release voltage to the motor) so if you have a question concerning where voltage ends, email
us at [email protected].
TESTING FUSES, BREAKERS, WIRING, AND SWITCHES
1) One of the most common problems with power outages is problems with fuses, breakers, wiring, or switches.
2) If your treadmill is equipped with a safety switch, set your volt meter to continuity. Touch your test leads together to make sure you
are getting a closed circuit. With the treadmill unplugged, back the leads off the safety switch, usually near the upper display computer.
With the safety key out, test the switch. It should be open. Push the safety key in. Your circuit should be closed. If this tests ok, move to
the next step.
3) While testing for voltage, you can unplug your treadmill and test the fuses, breakers, and wiring harnesses. Sometimes a breaker may
have shorted open and not tripped. Test these components individually. You want a closed circuit on all of them

instructions Things You'll Need

• Digital multimeter or analog multimeter

1. Using a digital multimeter
   • 1 Connect the test leads to the volt-ohmmeter. Plug the black test leads into the black jack marked "Com" or "Common" on the front of the meter. Plug the red test lead into the red jack marked "Volts/Ohms" on the front of the meter.
     
   • 2 Set the meter's function switch to "Ohms" and the range switch to the "R x 1" scale. If your digital multimeter is an auto ranging meter, you will not have a range switch. Instead, you'll have just a function switch because the meter will automatically select the right range for the quantity that you are measuring.
     
   • 3 Turn off the power and remove the fuse to be tested from the circuit. Never test a fuse for continuity while it is still connected to the circuit that it is used to protect. If the circuit still has voltage, the meter will be irreparably damaged. If the fuse is still in the circuit when tested it is possible to get a false indication that the fuse is good if the meter gets a completed circuit through other circuit components. To be safe, always remove the fuse from the circuit before testing it.
     
   • 4 Touch the black test probe to one end of the fuse and the red test probe to the other end of the fuse. It does not matter which probe you touch to which end because fuses are not polarized. You are checking to see if there is continuity through the fuse element. A reading of approximately 0.5 on a digital meter's LCD indicates a good fuse. Most digital meters read their own internal fuses resistance, hence 0.5 Ohms and not 0.00 Ohms. LCD readout of "O.L." indicates no continuity through the fuse. The fuse is bad and needs to be replaced
