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 – Notice Messages
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 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
button.
A 20
Sensor in an incorrect position during calibration.
Bring it to the position indicated and repeat the calibration.
A 20
Ultrasonic sensor calibration template in an incorrect position during calibration.
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
Incorrect wheel spin procedure on the wheel balancer without guard. The warning
appears when the spin button is pressed for more than 10 seconds without pressing
the "START" key at the same time. Release the button and spin the wheel according
to the procedure indicated in the "Wheel Spin" paragraph.
If the problem persists, 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
Spin performed with the guard raised.
Lower the guard to perform the wheel spin.
In machine versions with a start button, either the START key or the button released
during the spin.
Perform the spin holding down both the START key as well as the button.
– E – Error messages
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:
