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.
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.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.
Err. 24
Distance between the spokes
less than 18 degrees.
The minimum distance between the spokes where the
1.
unbalance is to be split must be greater than 18 degrees.
Repeat the SPLIT function increasing the distance between
2.
the spokes.
Err. 25
Distance between the spokes
greater than 120 degrees.
The maximum distance between the spokes where the
1.
unbalance is to be split must be less than 120 degrees.
2. Repeat the split function increasing the distance between the
spokes.
Err. 26
First spoke too far from the
unbalance
The maximum
1.
distance
between the unbalance position and
the spoke must be less than 120 degrees.
Repeat the split function increasing the distance between the
2.
spokes and the unbalance.
