13. Troubleshooting
Manually rotate the wheel. If the LED lights do not turn off and the machine starts balancing, check the
motherboard, position sensor and cables.
When rotating the wheel manually the screens don’t turn off and the machine begins balancing. Check
the motherboard, position sensor and cables.
After the machine has been powered on, the display stays blank. Check the indicator light of the power
switch. If the light isn’t on, the power source has an issue. Otherwise check the microcomputer,
motherboard and cables.
Epätarkkuus ei yleensä johdu koneesta. Se voi johtua renkaan huonosta asennuksesta koneeseen,
epätarkasta rengaspainosta tai epätarkasta 100 gramman kalibrointipainosta. Alkuperäinen 100 gramman
paino täytyy pitää huolellisesti tallessa itsekalibrointia varten. Inaccuracy isn’t usually caused by the
machine. It can be caused by the wheel being badly installed on the machine, inaccurate wheel weight or
inaccurate calibrating weight. The original 100 gram calibrating weight must be kept safe for future use.
If the data changes between balances, it isn’t caused by the machine. It can be caused by the wheel being
badly installed on the machine, or the machine not being properly installed to the floor. Attach the
machine to the floor with anchor bolts.
Hint:
Checking the accuracy of the wheel balancer
Input the rim’s correct data (values a, b, d) and do the self-calibration procedure. Measure the balance, and write
down the values the machine reads. After this, attach the 100 gram calibration weight to the outer edge of the rim
(the place, where all of the outer imbalance indicators light up). Run the balance measuring sequence again. Add
the outer imbalance value that the machine gave during the first measuring to the new value, and the result should
be 100±2. Rotate the wheel slowly until all of the outer imbalance indicators light up. Check if the 100 gram
calibration weight is at the 6 o’clock position. If the value you previously calculated isn’t near 100 or the
calibration weight isn’t at 6 o’clock, the machine isn’t accurate. You can check the inner balancing accuracy using
this same method.
