ERRORS
CAUSE POSSIBLE REMEDY
Black The wheel balancing machine does not
switch on.
1. Check the machine is properly connected to the mains power supply.
2. Check the fuses on the power board and replace if necessary.
3. Check display functioning.
4.
Replace the PC.
Err. 1
STOP button pressed with the motor
running.
1. Reset the error.
2. Repeat the spin.
Err. 2 Speed too low during measurement.
During the unbalance measurement
spins, the wheel speed dropped to
below 42 rpm.
Make sure that a vehicle wheel is mounted on the wheel balancing 1.
machine.
Use the self-diagnostics function to check the encoder.2.
Disconnect the measuring head connector from the board and perform 3.
a spin (if there is no error, replace the measuring heads)
Replace the computer board.4.
Err. 3 Unbalance too high. 1. Check the wheel dimensions setting.
2. Check the detection unit connections.
3. Run the machine calibration function.
4. Mount a wheel with a more or less known unbalance (defi nitely less
than 100 grams) and check the response of the machine.
5. Replace the computer board.
Err. 5 Guard open.
Guard opening during the measuring
cycle
1. Reset the error
2. Check functioning of the protection switch
