the new dimensions, or
to perform a wheel spin.
WARNING
If the diameter and distance values between the two balancing planes, recalculated on a
statistical basis starting from the rated geometric data of the wheel, exceed the normally
accepted interval stated in the technical data section, the message "A 5" is displayed.
4. ENTERING WHEEL DIMENSIONS IN
THE ALU 1P AND ALU 2P 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 balancing 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” mes-
sage is displayed.
The various methods for inserting dimensions are described below based on the supplied
devices:
- Move the end of the automatic measuring arm in line with the plane selected for the applica-
tion of the inner weight. In ALU 1P, the reference of the weight mid-point is the centre of the
gripper cavity (fig.19). In ALU 2P you must refer to the rim edge, because the inner weight is
of the spring type (fig.20).
- 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.
- bring the end of the automatic measuring arm in line with the plane selected for the applica-
tion of the outer weight (fig. 19a/20a) (following the procedure described above, 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 set up in the ALU P 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), use the
or
key to select the required programme.
