1. ERROR MESSAGES
The machine can recognise a certain number of malfunction conditions and signals them by displaying the relevant messages.
– A – Notice Messages
A 3
wheel not suitable for performing sensitivity calibration - use a wheel of average size (typically 5.5”X1440”) or a larger wheel weighing no more
than 40 kg.
A 5
Incorrect wheel data for an ALU programme. Correct the set dimensions.
A 7
The machine is temporarily not enabled to select the programme requested.
Perform a wheel spin, then repeat the request.
A 20
Internal sensor in an incorrect position during calibration.
• Bring it to the indicated position and repeat the calibration.
External sensor in an incorrect position during calibration.
• carry out the calibration procedure correctly;
• check the external sensor is at 5 +/-1 notch in the rest position;
• in service, check (with the pointer of the external sensor resting on the flange of the swinging unit) that about 167 +/-30 notches are
visualised.
• if the above points are not correct, adjust or replace the potentiometer.
A 23
Incomplete or incorrect data input in Precise ALU/EASY ALU Program. Repeat the input correctly.
A 26
Programme available only after selecting one of the following programmes: ALU 1P / ALU 2P / EASY ALU1/EASY ALU 2 / Motorcycle Dynamic /
Motorcycle ALU, or if selected in Motorcycle Programme but with the wheel NOT in 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 (without guard)" paragraph.
Check the proper operation of the spin button and check for damage to the Start key on the keyboard.
A 52
Started procedure for the assembly of the hub automatic wheel locking system. After 60 seconds the procedure ends automatically.
A Stp
Wheel stop during the spin phase.
The rotation of the unit stopped before completing the entire reading cycle:
• check the weight tray does not touch the unit during the spin;
• Check communication between the MBUGRF main board and the PEAL32F power board via the control signal ribbon cables (check picoflex
connection - replace cable and/or boards if necessary).
Wheel movement is not integral with swinging unit movement:
• make sure the wheel is tightened correctly.
A Cr
The contact of the micro-switch associated with the guard casing is open.
• check the correct working of the automatic start micro-switch associated with the wheel guard casing (with the guard lowered, the contact of
the switch must be closed);
• Replace the MBUGRF main board if the checks described above identified no faulty components.
• Spin performed with guard raised.
• Lower the guard to carry out the spin.
• On machine versions without wheel guard and without the spin button, check that the JUMPER is connected correctly on the main board.
– E – Error messages
E 1
Sensitivity calibration missing. Perform the sensitivity calibration procedure.
• The MBUGRF board has been changed. Perform the sensitivity calibration procedure.
E 2
Error condition on sensitivity calibration. Repeat the sensitivity calibration procedure.
Take particular care NOT to knock the machine during calibration.
Error condition during shaft assembly zero position setting.
