ALU 2 balancing programme:
Calculates statistically the balancing weights to
be applied on the inner side and the inner part
of the rim, as illustrated by the icon.
ALU 3 balancing programme:
Calculates statistically the balancing weights to
be applied on the inner part (inner and outer
side) of the rim, as illustrated by the icon.
ALU 4 balancing programme:
Calculates statistically the balancing weights to
be applied on the inner side and the inner part,
outer side of the rim, as illustrated by the icon.
ALU 5 balancing programme:
Calculates statistically the balancing weights to
be applied on the inner part and the outer side
of the rim, as illustrated by the icon.
- Correctly set the wheel data as described for
the Dynamic balancing program.
- Perform a spin.
- at the end of the spin, select the balancing
programme icon
knob or the ENTER button
the required programme is selected.
- The video displays instructions for where to
position the balancing weights relating to the
selected programme: always to 12 o'clock
if the weight is a conventional spring type,
whereas for the application of the adhesive
66
and press the Kis
until
weight, use 6 o'clock if the "LASER" config-
uration is active or 12 o'clock if the "H12" or
CLIP configuration is active.
- Set the wheel's rated geometric data by fol-
lowing the steps described in the WHEEL DATA
ENTRY chapter. If the values of the diameter
and of the distance between the 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 A
5 message is displayed.
IMPORTANT: in ALU1 and ALU2 programmes the
unbalance displayed by the machine on the
outer side refers to the adhesive weight centre
of gravity at the shaft assembly bearing flange,
see figure 25a.
- Some slight residual unbalances may remain at
the end of the test spin due to the considerable
difference in shape that may be found on rims
having the same rated dimensions. Therefore
change the value and position of the previously
applied weights based on the configuration
performed in the programme "SELECTION OF
ADHESIVE WEIGHTS APPLICATION POSITION"
until an accurate balance is obtained.
