18. 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 3
Wheel not suitable for performing the sensitivity calibration, use a wheel of
average dimensions (typically 5.5"X14") or larger, but NOT exceeding a weight
of 40kg.
A 5
Incorrect dimension settings for an ALU programme. Correct the set dimen-
sions.
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
Ultrasonic sensor calibration template in an incorrect position during calibra-
tion. Bring it to the indicated position and repeat 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 41
Contact the technical support centre.
A Stp
Wheel stop during the spin phase.
Wheel movement is not integral with swinging unit movement: Check correct
wheel tightening.
A Cr
Contact the technical support centre.
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 3 I/E 2/3 Error condition at the end of sensitivity calibration. Repeat the calibration, if
the message persists perform the following checks:
Correct sensitivity calibration procedure;
Correct fastening and position of the calibration weight;
Mechanical and geometric condition of the calibration weight;
geometry of the wheel used.
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
sensor is not present, or there is a distance-diameter measuring sensor fault,
call the technical support centre.
