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 measurement
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.
Detach the measuring head connector from the board and do a
3.
spin (if no error is detected, replace the measuring heads).
Replace the CPU board.
4.
Err. 3
Unbalance too high.
Check the wheel dimensions setting.
1.
Check the detection unit connections.
2.
Mount a wheel with more or less known unbalance (less than
3.
100 grams) and check the response of the machine.
Replace the CPU board.
4.
Err. 4
Rotation in opposite direction.
Use the self-diagnostics function to check the encoder.
1.
Check the encoder bearing/spring.
2.
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. 22
Maximum number of spins possible for
the unbalance measurement has been
exceeded.
1.
Check that a vehicle wheel has been mounted on the wheel balancer.
2.
Use the self-diagnostics function to check the encoder
3.
Replace the computer board.
Err. 23
The wheel does not slow down
1.
Remember to release the wheel when the displays go off
2.
Use the self-diagnostics function to check the encoder
3.
Replace the computer board.
