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(denitely 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rst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prole
measurement data from the acquisition
board to the PC
1. Repeattheoutsideprolemeasurement
2. Replace the acquisition board
Err. 9
Errorintransferoftheinsideprole
measurement data from the the
acquisition board to the PC
1.Repeattheinsideprole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
rotation, 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
Err. 20 Message management error (incorrect
or no translations) (only for releases
prior to M3343)
1. Change the language, selectable in Setup
2.ContactTechnicalServicetondoutiftheon-screenmessagescan
