Error code Problems
Err 6 Breaking of the carter micro switch.
Err 7 The gap of phases of the two
pick-ups is too wide.
Err 8 The internal pick-up is not con-
nected or defective.
Err 9 The external pick-up is not con-
nected or defective.
Err 10 Defect of the position detectors
in the optoelectronic system.
Err 10 The engine does not turn in the op-
toelectronic system.
Err 11 Defect of the detector of the zero pas-
sage in the optoelectronic system.

toelectronic system.

Causes and possible solutions
Substitute or reposition the electormagnet-
ic micro switch. (Chapter 6.5).
R
Verify that the weight for each calibra-
tion has been applied in a correct way.
R
Verify the position of the machine: maybe it
is not stable and it vibrates too much.
R
If the problem persists even after fixing the ma-
chine correctly, check the connection of the de-
tectors and of the electronic board.
R
Substitute the pick-ups. (Chapter 6.1 and chapter 6.4.1).
If the problem persists after changing the pick-ups, substitute the
board. (Read the charter of the Substitution of the board).
Check and substitute the internal pick-
up. (Chapter 6.1 and chapter 6.4.1).
Check and substitute the external pick-
up. (Chapter 6.1 and chapter 6.4.1).
R
Verify the connection of the optoelectronic device.
R
Verify that the optoelectronic device is protected by
the environment light and cover it if necessary.
If the imperfection persists, check and, if necessary, substitute the
optoelectronic device. (Chapter 6.2).
Check the electrical part, see the wiring diagram N. 654144.
R
Verify the connection of the optoelectronic device.
R
Verify that the optoelectronic device is protected by
the environment light and cover it if necessary.
If the imperfection persists, check and, if necessary, substitute the
optoelectronic device. (Chapter 6.2).
Check the electrical part, (see the wiring diagram N.654636).
R
Check that the wheel has been fixed correctly on the flange.
R
Search for the external position (anyway), ap-
ply a 100 gram weight and launch again.
If the problem persists, do the calibration again. (Chapter 5).
Set up the wheel data before making the measure launch
R
Maybe you inverted the connection of the two pick-ups: Check
(and change if necessary) the connection of the two pick-ups.
Substitute the pick-ups. (Chapter 6.1 and chapter 6.4.1).
Do not press the brake pedal when the engine is on.
R
Be careful not to hit the machine during the measuring.
R
Check the net tension. See the wiring diagram N. 654636.
Check the engine. (Chapter 6.3).
R
Verify that the optoelectronic device is protected by
the environment light and cover it if necessary.
R
If the imperfection persists, check and, if necessary, sub-
stitute the optoelectronic device. (Chapter 6.2).
Check and, if necessary, substitute the electronic board of the
control panel (Chapter Substitution of the board).
R
Check that the inverter has been properly connected.
R
Check that the motor is correctly connected.
R
Check and eventually replace the invert-
er assembly and/or the CPU board.
R
Check that he laser group is correctly connected.
R
Eventually replace the laser assembly.
R
Check that the laser group has been correctly connected.
R
Eventually replace the laser assembly.
R
Repeat the measuring.
R
If the error persists check that the wheel does
not have too big defects to be measured.
R
Check the correct fixing of the wheels.
R
Check if the other laser measurements are correct.
R
Repeat the measuring.
R
Check that the laser moves along its stroke before the cycle.
R
Check that the wheel does not come out of the measuring field.
R
Check that the laser emits a "red dot" light.
