Use and Maintenance Manual
ENGLISH
Code 24
Pneumatic spindle released during the
measuring cycle
1. Lock the wheel before starting the measuring cycle
2. Check that the wheel is correctly locked on the spindle and that the
pneumatic system air pressure is sufficient to hold it locked
Code 25
Rotation start timeout
1. Check that there are no obstructions to normal wheel rotation
2. Use the self-diagnostics function to check the encoder
3. Use the self-diagnostics function to check proper functioning of the
electromagnetic switch
4. Check the connection of the cables between the various boards
AC versions - Check functioning of the power board relay
CC versions - Replace the motor drive board
Code 26
Wheel braking timeout
1. Check functioning of the power board relay
2. Check the connection of the cables between the various boards
AC versions - Check functioning of the power board relay
CC versions - Replace the motor drive board
Code 27
Inverse rotation
1. Use the self-diagnostics function to check the encoder
Code 28
Unbalance measurement timeout
1. Repeat the unbalance measuring cycle
Code 29
Eccentricity measurement timeout
1. Repeat the eccentricity measuring cycle
Code 31/
Code 32/
Code 33
Error during motor speed calibration
1. Repeat the DC motor calibration function checking that there are
no obstructions hindering normal spindle rotation
2. Check the motor connections
3. Use the self-diagnostics function to check the encoder
Code 34
DC motor acceleration error
1. Check the motor connections
2. Check proper functioning of the motor belt
Code 35/
Code 45
ADC functioning error
1. Turn the wheel balancing machine off and on again
2. Replace the acquisition board
Code 36/
Code 37/
Code 38/
Code 39
Unbalance measurement error
1. Use the self-diagnostics function to check the encoder
2. Check detection unit connections
3. Verify machine earth/ground connection
4. Mount a wheel with more or less known unbalance (less than 100
grammes) and verify the response of the machine
5. Replace the acquisition board
Code 40/
Code 41/
Code 42/
Code 43
Runout measurement error
1. Check the connection of the runout measurement devices
2. Use the self-diagnostics function to check the encoder
3. Verify machine earth/ground connection
4. Replace the acquisition board

Code: all
Communication errors via Ethernet
between the PC and the acquisition
board
1. Turn the wheel balancing machine off and on again
2. Check the Ethernet connection cables between the PC and the
acquisition board
3. Replace the acquisition board
GENERAL
ERRORS
CAUSE
CHECKS
Unbalance
incorrect with
back centring
cones
Wheel slipping on the adapter because
the BP system is at the end of travel or
because of incorrect fitting of the tyre
tie-rod
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
The unbalance
is always (0-0)
The firmware version is not compatible
with the computer board GP1 Rev.04
Update the software of the machine to the M3700 version or higher,
and proceed with the firmware update
