MATRIX T3x - 05

Auto Calibration Procedure:
1) Press and hold the INCLINE DOWN and SPEED DOWN keys for three seconds until Manager appears on the middle LED display.
2) Press the SPEED or INCLINE UP key until Engineering appears on the display.
3) Press ENTER once Engineering is displayed.
4) Scroll between programs in the Engineering Mode using any UP or DOWN key until Auto Calibration appears on the middle LED display.
5) Press ENTER once Auto Calibration is displayed., you should not be standing on the running belt.
6) After completion, the display will either return to normal operation (if the unit passed the Auto Calibration) or display that the Auto Calibration failed.
Adjusting The running belt
After placing the treadmill in the position it will be used, the belt must be checked for proper tension and centering. The belt may need to be adjusted after the first 2 hours of use. Temperature, humidity, and use cause the belt to stretch at different rates. If the belt starts to slip when a user is on it, be sure to follow the directions below.
Step 1: Locate the two hex head bolts on the rear of the treadmill. The bolts are located at each end of the frame at the back of the treadmill. These bolts adjust the rear roller. Do not adjust until the treadmill is on. This will prevent over tightening of one side.
Step 2: The belt should have equal distance on either side between the frame. If the belt is touching one side, do not start the treadmill. Turn the bolts counter clockwise approximately one full turn on each side. Manually center the belt by pushing the belt from side to side. Tighten the bolts the same amount as when the user loosened them, approximately one full turn. Inspect the belt for damage.
Step 3: While the treadmill is running at 3 mph, observe the belt position. If it is moving to the right, tighten the right bolt by turning it clockwise 1/4 turn, and loosen the left bolt 1/4 turn. If it is moving to the left, tighten the left bolt by turning it clockwise 1/4 turn and loosen the right 1/4 turn. Repeat Step 3 until the belt remains centered for several minutes.
Step 4: Check the tension of the belt. The belt should be very snug. When a person walks or runs on the belt, it should not hesitate or slip. If this occurs, tighten the belt by turning both bolts clockwise 1/4 turn. Repeat if necessary.

Troubleshooting
Error message 01A8 / 01AD / 02B6 / 02B7 / 02B8
1) Cause:
a. 01A8 - Main motor over current of 7 Amps.
b. 01AD - Motor over temperature.
c. 02B6 - Speed up is over current.
d. 02B7 - Speed down is over current.
e. 02B8 - Running status over current.
2) Solution:
a. Perform an amp draw (see instruction for how to run an amp draw on Matrix treadmills). Flip the deck or replace the running belt as needed.
b. If the amp draw is normal, replace the MCB.
Error message 01AB
1) Cause:
a. Inverter error.
2) solution:
a. When the display is showing an 01AB error, the MCB Fault LED should be lit .
b. If the MCB Fault LED is not lit, replace the console.
c. If the MCB Fault LED is lit, replace the MCB.
Error message 02A0 / 02A8
1) Cause:
a. 02A0 - Main motor failure. The belt does not move when it is supposed to move.
b. 02A8 - Inverter circuit of the motor failed. Motor resistance is closed.
2) Solution:
a. Check the Motor wire connection between the Motor and MCB .
b. Press the start key and check the MCB PWM LED (Figures B).
-- If PWM LED does not flash, replace the console.
-- If PWM LED flashes, follow the steps below.
c. Use a multi - meter to check the 3 points (U / V / W) and see if there’s a resistance reading .
-- If yes, replace the MCB.
-- If no, replace the motor
Error message 02A1 / 02A2
1) Cause:
a. 02A1 - Over AC power input voltage.
b. 02A2 - Over / low DC bus voltage.
2) Solution:
a. Use a multi - meter to check if the input power matches local power specifications at the MCB. Switch to a different outlet if necessary.
- If a known good outlet is not providing the correct power, replace the power components as needed.
b. If the power input is ok, replace the MCB.
Error message 02AD
1) Cause:
a. MCB over temperature.
2) Solution:
a. Check the Motor wire connection between the Motor and MCB .
b. Use a multi meter to check the for a resistance value across the 2 blue wires of the motor wire .
-- If there is a resistance value, replace the MCB.
-- If there is not a resistance value, replace the motor.
Error message 02B9 / 02BA / 02BC / 02BD
1) Cause:
a. 02B9 - The inner memory IC data write error.
b. 02BA - The inner memory IC data read error.
c. 02BC - Ground connection or fuse error.
d. 02BD - Inverter hardware interrupt error.
2) Solution:
a. Replace the MCB.
Error message 04A0
1) Cause:
a. PCB communication disconnected.
2) Solution:
a. Check the console cable connection between the UCB and MCB
b. Replace the console cable if any damage is found.
c. Replace the console if the connections are good.
