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. 45 ADC functioning error ▪ Turn the wheel balancing machine off and on again
▪ Replace the computer board
Err. 80 Spotter operating error ▪ Check spotter connection
▪ Replace the spotter
Err. 81 Spotter control microswitch operating error ▪ Check the mechanical opening/closing control of the microswitch
inside the spotter
▪ Turn the machine off and on again and check that the spotter
correctly positions on zero
▪ Replace the spotter
Err. 82/
Err. 83
Spotter motor operating error ▪ Check spotter connection
▪ Check the mechanical opening/closing control of the microswitch
inside the spotter
▪ Check that there are no mechanical obstacles to the Spotter device
movement
▪ Replace the spotter
Err. 96 Spotter device calibration error ▪ Repeat the Spotter device calibration by following the instructions
Err. 97 Error in number of steps calculated for
spotter movement
▪ Repeat automatic measurement of the distance and diameter
▪ Calibrate the spotter
▪ Calibrate the distance gauge
▪ Calibrate the diameter gauge
▪ Check mechanical fitting of the spotter
Err. 98 Dimensions error ▪ Repeat the automatic measurement of the dimensions
▪ Calibrate the diameter gauge
Err. 99 Spotter home function timeout error ▪ Repeat automatic measurement of the distance and diameter moving
the gauge slowly
▪ Check spotter connection
▪ Replace the spotter
Err.100÷108 Spotter using error ▪ Repeat automatic measurement of the distance and diameter moving
the gauge slowly
Unbalance

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
