The machine can recognise a certain number of malfunction conditions and signals them
by displaying the relevant messages.
A 3
wheel not suitable for performing the sensitivity calibration, use a wheel of
average dimensions (typically 5.5"X14") or larger but with a weight that does
not exceed 40 kg.
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 20
Sensor in an incorrect position during calibration.
Bring it to the position indicated and repeat the calibration.
A 23
Incomplete or incorrect data entry in ALU P.
Repeat the input correctly.
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 31
Optimisation procedure (OPT) already launched by another user.
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.
E 1
Absence of sensitivity calibration.
Perform the sensitivity calibration procedure.
E 2
Error condition on sensitivity calibration.
Repeat the sensitivity calibration, paying attention to the first spin, which
must be performed with the wheel like the subsequent 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.
