Black
The wheel balancer does not
switch on.
Check the machine is properly connected to the mains power
1.
supply.
Check the fuses on the power board and replace if necessary.
2.
Replace the CPU board.
3.
Err. 1
No rotation signal.
Use the self-diagnostics function to check the encoder.
1.
Replace the encoder.
2.
Replace the CPU board.
3.
Err. 2
Speed too low during detection.
During the unbalance measure-
ment revolutions, the wheel speed
has fallen to below 42 rpm.
Make sure that a vehicle wheel is mounted on the wheel balancer.
1.
Use the self-diagnostics function to check the encoder.
2.
Disconnect the piezo connectors from the board and do a spin
3.
(if no error is detected, replace the piezo sensors).
Replace the CPU board.
4.
Err. 3
Unbalance too high.
Check the wheel dimensions setting.
1.
Check the detection unit connections.
2.
Run the machine calibration function.
3.
Mount a wheel with more or less know
4.
n unbalance (less than
100 grams) and check the response of the machine.
Replace the CPU board.
5.
Err. 4
Rotation in opposite direction.
Use the self-diagnostics function to check the encoder.
1.
Check the encoder bearing/spring.
2.
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. 6
Spindle open (SE version)
The guard has been closed
without fi rst closing the spindle
1. Reset the error
2. Close the spindle
3. Close the guard.
Err. 7
Err. 8
Err. 9
NOVRAM parameter read error
Switch off the machine and wait for at least ~ 1 min;
1.
re-start the machine and check it works properly.
Repeat machine calibration.
2.
Replace the CPU board.
3.
Err. 11
Too high speed error.
The average spinning speed is
more than
240 rpm.
1. Check functioning of the phase encoder and, in particular, the
reset signal.
2. Replace the computer board.
Err.14
Err.15
Err.16
Err.17
Err.18
Err. 19
Unbalance measurement error.
Use the self-diagnostics function to check the encoder.
1.
Check the detection unit connections.
2.
Check the machine earthing connection.
3.
Mount a wheel with more or less known unbalance (less than
4.
100 grams) and check the response of the machine.
Replace the CPU board.
5.
Err. 20
Wheel still. The wheel must
remain still for more than one
second after START.
Use the self-diagnostics function to check the encoder.
1.
Check the connections on the power board.
2.
Replace the CPU board.
3.
Err. 21
Motor on for more than 15
seconds.
1. Use the self-diagnostics function to check the encoder.
2. Check the connections on the power board.
3. Replace the CPU board.
