Error condition at the end of sensitivity cali-
bration. Repeat the calibration, if the message
persists perform the following checks:
• Correct sensitivity calibration procedure;
• Correct fastening and position of the calibra-
tion weight;
• Mechanical and geometric condition of the
calibration weight;
• Geometry of the wheel used.
E 6
Error condition when executing optimisation
programme. Repeat the procedure from the
beginning.
E 8
Printer out of service or not connected.
E 10
Internal measuring sensor not in the rest position.
E 11
Internal measuring sensor motor steps coun-
ting error.
E 12L
Faulty sensor external detector; enter the value
of the wheel width in manual mode.
If the error occurs again, call for assistance.
E 12M
External detector not in rest position.
If the error occurs again, call for assistance.
E 13
External measuring sensor motor steps coun-
ting error.
E 27
Excessive braking time. If the problem persists,
call in the technical support centre.
E 28
Encoder counting error. If the error occurs fre-
quently, call the technical support centre.
E 30
Spin device failure. Switch off the machine and
call in the technical support centre.
E 32
The wheel balancer was jolted during the reading
phase. Repeat the spin.
E 50
Automatic wheel clamping system failure.
Restart the wheel balancer.
If the error persists, request servicing.
E 99M
Serial communication error on the MBUGRF card
between the control unit and the graphic module.
If the error persists, request the technical support.
E 99A

If the error persists, request the technical support.
E F0
Swinging unit encoder error.
CCC - CCC
Unbalance values greater than 999 grams.
CHECK FOR CORRECT
FUNCTIONING OF
BALANCING ACCESSORIES
Checking balancing accessories allows the opera-
tor to make sure that wear has not altered the
mechanical specifications of flanges, cones, etc.
beyond the specified limits.
A perfectly balanced wheel, which has been
disassembled and reassembled in a different
position, should not show an unbalance value
greater than 10 grams.
When a higher unbalance is found, check all the
accessories carefully and replace the components
that are not in perfect condition (e.g. showing
dents, abnormal wear, flange unbalance, etc.).
Anyhow it is necessary to bear in mind that, if
the cone is used to centre the wheel, satisfactory
balancing results cannot be achieved if the central
hole of the wheel is out-of-round or incorrectly
centred; better results can be achieved by centring
the wheel using the securing holes.
Bear in mind that any re-centring error made
when the wheel is mounted on the car can be
removed only removed with an "on-the-vehicle
balancing" of the wheel, using an on-the-vehicle
wheel balancer to complement the work of the
wheel balancer.
