Check that the speed sensor cable is
connected to the MCB on the connector
labeled “SPEED”. If not, attach it (Error C
appears on the LED) and reset the treadmill.
Check the speed sensor cable is not pinched.
* If the Speed Sensor light flashes when you
turn the motor but Error 53 still immediately
appears when the treadmill is turned on it could
be the R64 resistor on the MCB.
EPROM is correctly installed but it self-tested the
code and saw an error.
Most likely solution is a new EPROM.
Check the wire from the Elevation Motor is correctly
plugged in at the connector labeled “INCLINE”.
If it is not plugged in, the walking belt will run as
normal but when the user tries to increase or
decrease incline the value will change on the
screen but the elevation will not move.
If the wire is plugged in then Complete an Elevation
Calibration to see if the problem is solved.
If that doesn’t solve the problem, check the
resistance in OHMS (between the black and white
wires (not red) at the elevation connection) at the
maximum elevation (should be 450 Ohms) and
minimum elevation (850 Ohms)

If the wiring is connected correctly then check the
Reed Switch is in the correct position inside the
console within range of the safety key magnet.
Check the reed switch is functioning correctly by
testing continuity on the reed switch.
The DC Voltage BUS is over its limit.
110V North American units should be
170 V DC so anything over 190 V DC
causes an Error “U”.
220V International units should be
350 V DC so anything over 380 V DC
causes an Error “U”
First, Check the AC power into the machine, it
should not exceed 125 V AC (N/A) or 240V AC
(International)
If the Power into the machine is OK then likely
solution is to change the Motor Control Board.

Quick Motor Functionality Test using a 9V Battery:
Remove the Drive Belt that is connected to the Drive Motor Pulley so the motor can turn easily.
Remove the Motor Wires and connect a 9V battery to the positive and negative connectors. When the
motor wires make contact with the battery terminals the motor should spin.
Thorough Motor Test:
Place a multimeter pin in each motor wire connector and check the resistance.
You should get a reading between 0.9 & 1.6 OHMS. If you get a slightly lower or higher reading then
turn the flywheel a small amount and test again. A slightly higher or lower reading can be caused if the
reading was taken between poles (e.g. lower than 0.9 or up to 4 ohms). If you get “OL” (Overload) on
the multimeter then you have an open circuit in the motor and will likely have it in every position you try
to take a reading. The above-mentioned Quick Motor Functionality Test would fail if you have an open
circuit. You need to confirm if the “OL” is being caused by the Motor Brushes not making contact with
the commutator or an error inside the motor.
Check the Motor Brushes are making good contact with the commutator then it is possible that the
circuit has been opened inside the motor causing the “OL” which requires a motor change.

Hardware current limit has
been exceeded for a very
short period of time.
This means that there is too much current but not high enough to represent a short-circuit which would
create an Error 52.
This can be created by holding back the running belt. Check that nothing is jamming the walking belt,
rollers, drive belt or motor from turning.
A defective component on the MCB may also cause this and therefor change the MCB.
Belt Speed Incorrect
If the actual belt speed is less than 80% or more than 120% of the required speed for more than 5
seconds then an Error 56 will appear.
e.g. if the required speed is 5 mph, then an Error 56 will appear if the actual speed reading is less than
4.0mph or greater than 6.0mph. (+ or -20% for 5 seconds)
Check if something is causing the walking belt, rollers, drive belt or motor from turning.
If not, it is likely a fault on the MCB and needs to be changed.

REQUIRED
TOOLS
Hex Key
Rear Roller
Screw
If the walking belt is not centered and is running to one side then it needs to be
realigned before it hits the foot rails and permanently damages the belt.
Frayed belts damaged from hitting the foot rail are not covered by the parts
warranty, as it is considered user error.
WARNING – Do not stand on the belt during this procedure and keep loose
clothing and long hair away from the belt and rollers.
NOTE – During the belt alignment procedure you may be required to make
several minor 1/4-turn adjustments to the rear roller screws. Never turn a
single screw more than 1 full revolution clockwise in total. Exceeding this may
over tighten the walking belt and cause a high amount of tension that can
result in premature wear of the belt, roller and motor. To prevent this problem,
it is best to adjust only one alignment bolt to centre the walking belt.
To adjust the walking belt alignment:
1. Enter the DIAGNOSTICS Menu and select BELT
ALIGNMENT (For a T240S-T280S-T520S: select “d2”)
and press JustGoTM to accept.
2. Allow the belt to reach 2.0 mph or 3.2 km/h. Stand at the
rear of the treadmill and note the gap between the right
and left sides of the belt (A) and the foot rails (B).
If the running belt is tracking (moving) to the left turn
the left rear roller screw (B) clockwise or turn the right
rear roller screw (B) counter-clockwise to allow the belt to
track to the right and towards the centre.
If the running belt is tracking (moving) to the right
turn the left rear roller screw (B) counter-clockwise or the
right rear roller screw (B) clockwise to allow the belt to
track to the left towards the centre.
3. WALKING BELT ALIGNMENT VERIFICATION
In order to verify that the running belt is aligned correctly, slowly increase the speed to a
maximum of 6.0 mph or 9.6 km/h, and let the belt turn for a least one (1) minute. Carefully
observe that the belt stays centered. If it does, move on to the next step.
However, if the walking belt continues to track to one side, or you hear a rubbing noise (the
belt may be touching the foot rails), immediately press the STOP key to stop the belt. You
will need to complete the alignment procedure again.
4. WALKING BELT TENSION VERIFICATION
Finally you need to confirm that the walking belt tension is correct. Start the treadmill and
begin walking on the belt. Slowly increase the speed to 2.0 mph or 3.2 km/h and check to
see that the belt runs smoothly and does not pause or stop each time you plant your foot. If
the belt does run smoothly, gradually increase the speed all the way to the maximum to
confirm that the tension is correct for all speeds. If at any time during this process the belt
does hesitate, stop the treadmill and TURN BOTH of the rear roller screws exactly ¼-turn
clockwise, which tightens the belt and restart the walking belt tension verification.

WARNING – Do not stand on the belt during this procedure. If the incline calibration is
interrupted, do not use the treadmill. It is important to fully complete the incline calibration
procedure again before using the treadmill.

1. Enter the Diagnostics menu by pressing and holding the iTek button for 3 seconds.
2. You have correctly accessed the Diagnostics menu when you see DIAGNOSTICS on
screen and a scrolling message: “TXXX VERSION”.
3. Use the SPEED INCREASE & DECREASE keys to scroll through the Diagnostics menu
until ELEVATION CALBRATION is on screen.
4. Press the Just Go key twice to begin the Elevation Calibration
5. Once you see “COMPLETE” on the display, press the “Stop” key 4 times to return to the
“Welcome Screen”. Your treadmill is ready to go.
2012 T240S, T240S0, T260P, T280S, T280PO, T460XC, T520P, T560X
1. Remove the motor cover.
2. Locate the Incline Calibration button labeled “INCLINE”. It is
directly below the EPROM and above the LED Display on the
left side of the board. (See picture to right.)
3. Press and hold the button down for 3 seconds. The platform
will start elevating. As soon as the platform begins elevating,
release the button and the calibration will perform on its own (it
will last about 1 minute).
4. When the calibration is completed, start the unit and test the
speed and incline function correctly.
1. Reinstall the motor cover onto the treadmill.
