These programs are recalled from the main menu using the icon,
opens the submenu of seven icons in two groups: ALU P and normal ALU programs.
These programs are used for maximum precision balancing on light aluminum rims
that require the application of both weights on the same side (inner) in relation
to the rim disk.
After selecting the icon,
programs.
ALU 1P
The screen shows the video page for measuring imbalances on alloy wheels.
With the ALU P programs the user can define the balancing planes on which the
stick-on weights are to be applied with absolute precision, and in relation to the
specific shape of the rim. However, bear in mind that in order to reduce the size
of the weights to be applied, it is best to select balancing planes as far apart as
possible; if the distance between the two planes is less than 37 mm (1.5") the
message "Err 5" is displayed.
To perform the measurement:
- Move the end of the inner automatic sensor in correspondence with the plane
chosen for application of the inside weight. In Alu 1 P, the centre of the groove on
the end of the arm, in which the adhesive weight for application will be placed
(fig.18a) is taken as reference. In Alu 2 P reference is made to the edge of the rim,
since the inside weight is of the traditional clip-on type (fig.14).
Make absolutely certain that the end of the sensor is positioned in an area free
of discontinuity, so that the weight can be applied in the same position.
- Keep the arm in position. After two seconds the machine will give a beep to
confirm that the distance value has been acquired.
- Bring the end of the automatic sensor arm onto the plane chosen for application
of the outside weight (fig. 18b), as already described for the inside of the rim.
- Keep the arm in position and wait for the beep of confirmation.
If the measuring arm is returned to the rest position after acquisition of the data
for one plane only, or if the data of the outside plane have been acquired before
those of the inside plane, the message "Err 23" appears and the data entered are
ignored.
- The machine now presets for input of the nominal diameter of the wheel.
- Modify the diameter value displayed by pressing the arrow keys
set the number required.
The diameter can be set in millimetres or the values already set can be
