The machine can recognize a certain number of incorrect operations and will signal
them with appropriate messages on the display.
Err 1 Error in first sensitivity calibration.
The sensitivity calibration procedure should be carried out.
Err 3 Error in the execution of the sensitivity calibration procedure.
Make sure that the sample weight has been applied and repeat
calibration.
Err 4 Sensor calibration error.
The sensor calibration procedure should be carried out.
Err 5 Incorrect wheel data for aluminum wheel balancing program.
Correct the dimensions set.
Err 6 Error made during the OPT procedure (optimization).
Repeat the procedure from the beginning.
Err 7 The machine is temporarily unable to select the program requested.
Carry out a spin and repeat the request.
Err 8 Printer out of service; printer not present; printer failure.
Err 9 Imbalance value over 999 grams with car wheels or over 1990 grams with
truck wheels.
Reduce the imbalance and repeat the wheel spin.
Err 10 a) Internal distance sensor not in rest position (completely in) when the
machine is switched on.
Switch off the machine, return the sensor to its correct position and
switch on again.
b) Potentiometer malfunction. Select the Manual data input icon
to disable the sensors and enter the data by hand.
Call in the technical service.
Err 13 Attempt to perform calibration with incorrect wheel- machine distance.
Repeat calibration after fitting a spacer ring to alter the distance or use a
different wheel.
Err 20
Sensors in incorrect position during calibration.
Bring them to the position indicated and repeat the calibration.
Err 23 Incomplete or incorrect data entered in ALU P.
Repeat acquisition process correctly.
Err 25 Program not available on this model.
Err 27 Wheel did not stop within the maximum allowed time.
If this message appears frequently contact your service centre.
Err 28 Encoder error. If this message appears frequently contact your service
centre.
Err 30 During the wheel spin the wheel has not started to rotate within the
maximum permitted time. Repeat the wheel spin; if the error persists call in
the technical after sales service.
Err 31 Optimisation procedure already started by another user.
Err Rot "Zero" reference not found. Turn the wheel shaft by hand until the error
message disappears.
