Error code Problems
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.
Err 11 The engine does not turn in the op-
toelectronic system.
Err 17 The weight is out of adjustment field
(the suitable weight to balance the
wheel is higher than 250 grams).
Err 18 The wheel data have not been set up.
Err 19 The signal at the entry of the right pick-up is
less intense than the one of the left pick-up.
Err 20 The brake pedal has been pressed
during the measuring.
Err 20 The rotation speed of the engine is irregular.
Err 21 The electronic board has detected a dan-
gerous situation because of the extreme-
ly high speed of the wheel during a phase
of inaction (the shaft turns at a high
speed without the start of the opera-
tor): the power electric part is disabled.
Err 22 Irregular signals of the optoelectronic device.
Err 23 The gauge for the measure of the dis-
tance is not in rest position.
EEE EEE Two buttons pressed at the same time.
EEE EEE Defective keyboard.

Causes and possible solutions
+ Verify that the weight for each calibra-
tion has been applied in a correct way.
+ Verify the position of the machine: maybe it
is not stable and it vibrates too much.
+ If the problem persists even after fixing the ma-
chine correctly, check the connection of the de-
tectors and of the electronic board.
+ 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 right pick-up. (Chap-
ter 6.1 and chapter 6.4.1).
+ Verify the connection of the optoelectronic device.
+ Verify that the optoelectronic device is protected by
the environment light and cover it if necessary.
+ If the imperfection persists, check and, if necessary, sub-
stitute the optoelectronic device. (Chapter 6.2).
Check the electrical part, see the wiring diagram N. 654144.
+ Verify the connection of the optoelectronic device.
+ Verify that the optoelectronic device is protected by
the environment light and cover it if necessary.
+ If the imperfection persists, check and, if necessary, sub-
stitute the optoelectronic device. (Chapter 6.2).
Check the electrical part, see the wiring diagram N. 654144.
+ Check that the wheel has been fixed correctly on the flange.
+ 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.
+ Check that the gauges are enabled. (Chapter 4).
+ 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.
+ Be careful not to hit the machine during the measuring.
+ Check the net tension. See the wiring diagram N. 654144.
+ Check the engine. (Chapter 6.3).
+ Turn off the machine, push down the protecting cart-
er and then turn on the machine without moving the
wheel: if the problem persists, you need to check or sub-
stitute the electronic part: board (chapter Substitu-
tion of the board) or encoder (chapter 6.2.).
+ Verify that the optoelectronic device is protected by
the environment light and cover it if necessary.
+ 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).
+ Verify that the gauge is in rest position.
+ Check the analog value at 5. (chapter 6.4.4).
Repeat the calibration of gauges.
+
Press one button at a time.
Check and, if necessary, substitute the electronic board of
the control panel (Chapter Substitution of the board).
