4. ENTERING WHEEL DIMENSIONS IN
THE ALU1P OR ALU2P BALANCING
PROGRAMMES
With this programme the real wheel data have to be set in relation to the real balancing
planes rather than the nominal values (as in standard ALU programmes). The balanc-
ing planes where the adhesive weights are to be applied may be selected by the user
according to the specific shape of the rim. It should be remembered, however, that in
order to reduce the quantity of the weight that is to be applied it is preferable to select
balancing planes that are as far apart as possible: if the distance between the two planes
is less than 37 mm (1.5”), the “A 5” message is displayed.
The various methods for inserting dimensions are described below based on the sup-
plied devices:
With the version with automatic sensor, proceed as follows:
- Move the end of the automatic measuring arm in line with the plane selected for the
application of the inner weight. In Alu 1P the centre of the notch in the holder is used
as the reference for the centre line of the weight (fig.14). In Alu 2P refer to the rim edge,
since the inner weight is of the clip type (Fig.15).
- Keep the arm in position. After two seconds the machine emits an acoustic confirmation
signal to indicate that the distance and diameter values have been acquired.
- Move the end of the automatic measuring arm in correspondence with the plane selected
for the application of the outer weight (Fig. 14a/15a), in the same manner as described
previously for the inner side.
Pay maximum attention when the end of the arm is being placed in an area of the
rim free of discontinuity, so that the weight can be applied in that position.
- Keep the arm in position. After two seconds the machine emits an acoustic confirmation
signal to indicate that the distance and diameter values have been acquired.
- Return the measuring arm to the rest position. Automatically the machine will setup in
the ALUP balancing programmes (FSP programme).
- Carry out a spin.
- At the end of the spin, if you want to change the balancing programme set automatically
by the machine (FSP), select the
or
key until the required programme is
selected.
