19. MESSAGES ON THE DISPLAYS
The machine can recognise a certain number of malfunction conditions and signals them to the
user by visualising the relevant messages on the displays.
A 5 Incorrect dimension settings for an ALU programme. Correct the set dimensions.
A 7 The machine is temporarily unable to select the requested programme.
Perform a wheel spin, then repeat the request.
A 10 Internal sensor not in the rest position. Return the sensor to the rest position
(completely in). If the message does not disappear, internal sensor operation can
be disabled by pressing the
A 20 Sensor in an incorrect position during calibration.
Bring it to the position indicated and repeat the calibration.
A 26 Programme available only after selecting one of the following programmes: ALU 1P
/ ALU 2P / Motorcycle Dynamic / Motorcycle ALU or if selected in the Motorcycle
Programme but with the wheel NOT in the centred position.
A Stp Wheel stop during the spin phase.
Wheel movement is not integral with swinging unit movement: Check correct wheel
tightening.
A Cr
Spin performed with the guard raised.
Lower the guard to perform the wheel spin.
E 1
Absence of sensitivity calibration.
Perform the sensitivity calibration procedure.
E 2 Error condition during sensitivity calibration.
Repeat sensitivity calibration paying attention to the first spin, which must be
performed with the wheel as in the successive spins.
Take particular care NOT to knock the machine during calibration.
E 4 a) External mechanical sensor calibration error condition. Perform the external
mechanical sensor calibration procedure.
b) if the error continues after calibrating the external sensor or the external sen-
sor is not present, or there is a distance-diameter measuring sensor fault, call the
technical support centre.
E 6
Error condition when executing optimisation programme.
Repeat the procedure from the beginning.
E 12 a) Mechanical width sensor not in the rest position when machine was switched on.
Switch off the machine, return the sensor to the correct position and switch back
on. If the error persists, call in the technical support centre.
b) External sensor not present or faulty. Visualisation of this error can be disabled
by performing the following procedure:
• press the
