Err. 11 Speed too high error
During unbalance measurement rotation,
wheel speed is more than 270 rpm
▪ Check in self-diagnostics that the encoder functions properly
▪ Replace the computer board

Unbalance measurement error ▪ Check in self-diagnostics that the encoder functions properly
▪ Check detection unit connections
▪ Verify machine earth/ground connection
▪ Mount a wheel with more or less known unbalance (less than 100
g) and verify the response of the machine
▪ Replace the computer board
Err. 20 Wheel still. The wheel must remain still
for more than one second after START
▪ Use the self-diagnostics function to check the encoder
▪ Check the connections on the power board
▪ Replace the computer board
Err. 21 Motor on for more than 15 seconds ▪ Use the self-diagnostics function to check the encoder
▪ Check the connections on the power board
▪ Replace the computer board
Err. 24 Distance between the spokes less than
18 degrees
▪ The minimum distance between the spokes where the unbalance
is to be split must be greater than 18 degrees
▪ Repeat the SPLIT function increasing the distance between
the spokes
Err. 25 Distance between the spokes greater
than 120 degrees
▪ The maximum distance between the spokes where the unbalance
is to be split must be less than 120 degrees
▪ Repeat the split function increasing the distance between the
spokes
Err. 26 First spoke too far from the
unbalance
▪ The maximum distance between the unbalance position and
the spoke must be less than 120 degrees
▪ Repeat the split function increasing the distance between the-
spokes and the unbalance
Err.230÷238 Operating touch monitor errors ▪ Restart the balancing machine
▪ Calibrate the touch monitor
▪ Check touch monitor connections
▪ Replace the touch monitor
Err. 240 Machine setting error ▪ Execute the initialization function
Err. 241 Estimated width dimension ▪ Manually set the correct rim width value before calibrating the
machine
Unbalance
incorrect

Mount the wheel in vertical position and
push the sleeve up against the wheel. If
necessary, repeat locking/unlocking/
locking and perform the procedure again
