SOFTWARE
ERRORS
CAUSE POSSIBLE REMEDY
Black The wheel balancing machine does not
switch on.
1. Check the machine is properly connected to the mains power supply.
2. Check the fuses on the power board and replace if necessary.
3. Check display functioning.
4. Replace the PC.
Err. 1 STOP button pressed with the motor
running.
1. Repeat the measuring cycle avoiding to press the STOP button
unless for an emergency.
Err. 2 Speed too low during measurement.
During the unbalance measurement
spins, the wheel speed dropped to
below 42 rpm.
1. Make sure that a vehicle wheel is mounted on the wheel balancing machine.
2. Use the self-diagnostics function to check the encoder.
3. Disconnect the measuring head connector from the board and perform
a spin (if there is no error, replace the measuring heads)
4. Replace the acquisition board.
Err. 3 Unbalance too high. 1. Check the wheel dimensions setting.
2. Check the detection unit connections.
3. Run the machine calibration function.
4. Mount a wheel with a more or less known unbalance (definitely less
than 100 grams) and check the response of the machine.
5. Replace the acquisition board.
Err. 5 Guard open.
Guard opening during the measuring
cycle
1. Check functioning of the protection microswitch
2. Repeat the measurement keeping the guard closed until the end
of the spin.
Err. 6 Spindle open
Spin enabled without first having closed
the spindle.
1. Check functioning of the spindle closing microswitch
2. Close the spindle
3. Lower the guard
Err. 8 Error in transfer of the outside profile
measurement data from the acquisition
board to the PC.
1. Repeat the outside profile measurement.
2. Replace the acquisition board.
Err. 9 Error in transfer of the inside profile
measurement data from the the acquisi-
tion board to the PC.
1. Repeat the inside profile measurement.
2. Replace the acquisition board.
Err. 10 The inside adhesive weight distance is
greater than the outside adhesive weight
distance.
1. Repeat the wheel dimension measurement.
2. Repeat the laser calibration function.
3. Replace the acquisition board.
Err. 11 Speed too high error.
During unbalance measurement rota-
tion, wheel speed is more than 270 rpm.
1. Use the self-diagnostics function to check the encoder.
2. Separate the encoder cable from the motor power cable.
3. Replace the encoder.
4. Replace the acquisition board.
Err.15 Error dimensions stored invalid (only for
releases prior to M3390).
1. Repeat the wheel dimension measurement.
2. Use the self-diagnostics function to check proper functioning of the
lasers.
3. Replace the acquisition board.
Err. 16 Internal laser position error during the
machine calibration function.
1. Check that the internal laser is in the rest position.
2. Use the self-diagnostics function to check proper functioning of the
internal laser.
3. Check proper functioning of the microswitch that detects the internal
laser in rest position.
4. Turn off the wheel balancing machine, turn it back on again and
directly access the machine calibration screen.
