Error code Problems
Err9
The external pick-up is not connected or
defective.
Err10
Defect of the position detectors in the
optoelectronic system.
Err10
The engine does not turn in the optoelectronic
system.
Err11
Defect of the detector of the zero passage in
the optoelectronic system.
Err17
The weight is out of adjustment field (the
suitable weight to balance the wheel is higher
than 250 grams).
Err18
The wheel data have not been set up.
Err19
The signal at the entry of the right pick-up is
less intense than the one of the left pick-up.
Err20
The brake pedal has been pressed during the
measuring.
Err20
The rotation speed of the engine is irregular.
Err21
The electronic board has detected a
dangerous situation because of the extremely
high speed of the wheel during a phase of
inaction (the shaft turns at a high speed
without the start of the operator): the power
electric part is disabled.
Err22
Irregular signals of the optoelectronic device.
Err23
The gauge for the measure of the distance is
not in rest position.
EEE EEE
Two buttons pressed at the same time.
EEE EEE
Defective keyboard.

Causes and possible solutions
R Check and substitute the right pick-up. (Chapter 9.5).
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.
R If the imperfection persists, check and, if neces-
sary, substitute the optoelectronic device. .
R Check the electrical part (Chapter 11)
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.
R If the imperfection persists, check and, if neces-
sary, substitute the optoelectronic device.
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.
R If the problem persists, do the calibration again. (Chapter 7).
R Set up the wheel data before making the measure launch.
R Check that the gauges are enabled.
R Maybe you inverted the connection of the two pick-ups: Check
(and change if necessary) the connection of the two pick-ups.
R Substitute the pick-ups. (Chapter 9.5).
R 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. (Chapter 11)
R Check the engine. (Chapter 8.3).
R Turn off the machine, push down the protecting carter and
then turn on the machine without moving the wheel: if the
problem persists, you need to check or substitute the elec-
tronic part: board (Chapter 9.2) or encoder (chapter 8.2).
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 neces-
sary, substitute the optoelectronic device.
R Check and, if necessary, substitute the electro-
nic board of the control panel (Chapter 9.2).
R Verify that the gauge is in rest position.
R Check the analog value at 5. (chapter 8.4).
R Repeat the calibration of gauges.
R Press one button at a time.
R Check and, if necessary, substitute the electro-
nic board of the control panel (Chapter 9.2).
