Problems and error codes

During the working of the balancing machine, there can be several problems If the microprocessor detects them,
they appear on the display through the notice „Er" followed by a number which stands for the meaning.
Here is a list of the general malfunctions and the error codes with their respective and possible solutions:
Error code Problems
The machine does not turn on.
After having selected the programme and
having pressed the button OK the machine
does not start.
After the launch, the machine does not brake.
After the engine starts, it does not stop (even
if you turn the machine on and off, the engine
starts immediately).
Unbalance values are not steady when you
make several consecutive launches on the
same wheel (variations higher than 5 gr.).
Err 0 Generic problem
Err 1 The board has lost the calibration and
configuration data set up in factory.
Err 1 One or more calibration or configura-
tion steps have not been made.
Err 2 The protecting carter has been lift-
ed up before the end of the measure.
Err 3 During the spin (when you pressed
START or lowered the carter) the
wheel was turning backwards
Err 3 Inverted windings of the engine
Err 4 The engine does not reach the neces-
sary turns for a good balancing.
Err 4 Malfunctioning of the electronic board.
Err 4 Malfunctioning of the electric circuit.
Err 5 The calibration weight has not been applied
to the wheel.
Err 5 The pick-ups have not been connected.
Err 6 The protecting carter is not down.

Causes and possible solutions
R
Absence of power supply from the outside or ab-
sence of a phase. Check that the phase and the neu-
tral are connected to the balancing machine.
R
Breaking of the fuses in the electric circuit (see the wiring di-
agram N. 654636). Substitute the fuses with other identi-
cal fuses having the same characteristics. A new break of
the fuses involves a malfunction in the electrical part.
R
Breaking of the fuses in the electric circuit (see the wiring di-
agram N. 654636)). Substitute the fuses with other identi-
cal fuses having the same characteristics. A new break of
the fuses involves a malfunction in the electrical part.
R
Substitute the board (Chapter Substitution of the board).
R
Check the electric circuit with a tester (See diagram n.654636).
R
Check the microswitch of the cover (cap.6.5).
R
Check the inverter assembly (chap. motor and inverter).
R
Check the motor (chap.6.3).
R
Replace the board (chap. board replacement).
Check/substitute the inverter plant.
Check/substitute (Chapter Substitution of the board).
Check the inverter plant, disconnect the machine from the
electrical system for about 30 sec in order to discharge the
condersers and restart.
Substitute the board. (Read the paragraph of the Substitution of
the board).
N.B.: to understand if the problem is in the inverter or on the
board, you only need to take off the board connector from the
inverter.
Recalibrate (chapter.2.5).
Check the tension and the phase o the pick-ups(chapter 6.1 and
chapter 6.4.1).
Check the correct locking of the wheel on the flange.
Check that the cone-flange is properly assembled.
Make other tests with another wheel or be sure that there are no
movable part inside (ex. Water, sand, etc.).
Disconnect the power supply for about 30 sec and restart.
Substitute the board. (Read the paragraph of the Substitution of
the board).
Recalibrate and reconfigure the balancing machine (Chapter 2.5).
R
Make the missing calibrations steps. (Chapter 4 and chapter 5).
R
If the error persists, substitute the board.
R
Before lifting up the protecting carter, wait un-
til the launch of the measure has been completed.
Check the micro switch. (Chapter 6.5).
Be sure that the wheel is not moving during the start. An-
yway, do not turn it backwards during the start.
Verify the correct connection of the engine. (Chapter 6.3).
Check that the condenser plant works properly.
Check the net tension and the wiring diagram N. 654636).
Substitute the electronic board. (Chapter Substitution of the
board).
Substitute the engine. (Chapter 6.3).
Check and if necessari substitute the inverter plant.
Check the driving belt.
Repeat the calibration procedure from the beginning and apply the
calibration weight when the calibration requires to. (Chapter 2.5).
Check the connection of the pick-ups. (Chapter 6.1 and chapter
6.4.1).
Check that the automatic closing time of the carter is not too high.
