6.4.3 - CHANGE OF GAUGE CHARACTERISTIC
[P.Ph.]

 set to OFF:

ALUM and ALU3M adhesive weights can be applied by:
- applying the weights manually at 12 o’clock
- applying the weights positioning them on the clip and pulling out the distance gauge up to the correct axial position.

[P.Ph.]

 set to ON:

The ALUM and ALU3M adhesive weights can only be applied using the weight clip.

N.B.: Remember to always check the angular weight application position (LEDs all on).

7 - ERRORS

During machine operation, various causes of faulty operation could occur. If detected by the microprocessor, they appear 
on the display as follows:

ERRORS   CAUSES 

 

 

            CONTROLS

Black

The wheel balancer does not turn on.

1. 

Check proper connection to the mains.

2. 

Check and if necessary replace the fuses on the power board.

3. 

Replace the computer board.

Err. 1

No rotation signal.

1. 

Check belt tautness.

2. 

Check functioning of the phase encoder and, in particular, the reset 
signal.

3. 

Replace the phase encoder.

4. 

Replace the computer board.

Err. 2

Too low speed during measurement.
During the unbalance measurement 
revolutions, the wheel speed has fallen to 
below 42 rpm.

1. 

Check that a vehicle wheel has been mounted on the wheel 
balancer.

2. 

Check belt tautness.

3. 

Check functioning of the phase encoder and, in particular, the reset 
signal.

4. 

Replace the computer board.

Err. 3

Too high unbalance.

1. 

Check the wheel dimension setting.

2. 

Check the sensor connections.

3. 

Run the machine calibration function.

4. 

Mount a wheel with a more or less known unbalance (less than 100 
grams) and check the machine response.

5. 

Replace the computer board.

Err. 4

Rotation in opposite direction.
After pressing [START], the wheel 
starts turning in the opposite direction 
(anticlockwise).

1. 

Verify the connection of the UP/DOWN - RESET signals on the 
phase encoder.

Err. 5

Guard open
The [START] pushbutton was pressed 
without 

fi

 rst closing the guard.

1. 

Reset the error.

2. 

Close the guard.

3. 

Verify the function of the protection Switch.

4. 

Press the [START] button.

Err. 7 / 
Err. 8 /
Err. 9

NOVRAM parameter read error

1. 

Repeat machine calibration

2. 

Shut down the machine.

3. 

Wait for at least ~ 1 min.

4. 

Restart the machine and check proper functioning.

5. 

Replace the computer board.

Err. 11

Too high speed error.
The average spinning speed is more than  
240 rpm.

1. 

Check if there is any damage or dirt on the phase encoder disc.

2. 

Check functioning of the phase encoder and, in particular, the reset 
signal.

3. 

Replace the computer board.

Err.14/
Err.15/
Err.16/
Err.17/
Err. 18/
Err. 19

Unbalance measurement error.

1. 

Check functioning of the phase encoder.

2. 

Check the sensor connections.

3. 

Check the machine earthing connection.

4. 

Mount a wheel with a more or less known unbalance (less than 100 
grams) and check the machine response.

5. 

Replace the computer board.

Err.20

Wheel at standstill. The wheel is at a
standstill for more than one second after
START.

1.    Check functioning of the phase generator.
2.    Check the connections on the power board.
3.    Replace the computer board.
