needs to be hidden behind two spokes for
aesthetic reasons. This programme subdivides
the outer balancing weight (Pe) into two equal
weights (P1 and P2) placed in concealed positions
behind two spokes of the alloy rim.
α ≤ 120°
The two weights must be placed within an arc of
120°, including the Pe weight.
To start this programme, proceed as indicated
below:
- Select one of the balancing programmes,
ALU1 or ALU2.
- Perform a spin.
- At the end of the spin, if there is an unbalance
on the outer side (Pe), the machine will display
the Hidden Weight button
the main screen.
- Press this button;
- The machine performs a full-speed low speed
wheel during which, by means of the front
laser triangulator, recognizes the number of
spokes in the rim;
- At the end of the on-screen procedure appears
the image of the imbalances with two position
indicators for the outside. The unbalance
value displayed for this side refers to the
indicator in the centered position.
The application of each of the two balancing
weights is carried out as described in the
paragraph "Applying balancing weights".
If the operator wants to change the position
of the imbalances automatically calculated
by the machine, it is possible to perform the
procedure in MANUAL mode by pressing the
EM9780 plus - EM9780 C plus AutomaticLine - Operator's manual
above button again
the internal laser pointer will automatically
move onto the outer plane (Pe).
- Turn the wheel clockwise until you reach the
point where you want to apply the first outer
weight (P1) and align the laser point with a
spoke.
- press the
button on the monitor to confirm the opera-
tion;
- Turn the wheel anticlockwise until you reach
the point where you want to apply the second
outer weight (P2) and align the laser point with
18 the second spoke.
- press the
button on the monitor to confirm the opera-
tion;
- When the procedure is completed, the unbal-
ance image is displayed on the screen includ-
ing two position indicators for the outer side.
The unbalance value displayed for this side
refers to the indicator in the centred position
condition.
Each of the two balancing weights is applied as
described in the "Balancing weight application"
on
section.
CAUTION:
If the machine in automatic mode is not able
to recognize the rims of the rim, the program
is predefined manually at the end of the cycle.
You can quit the Hidden weight procedure at
any time by simply pressing the Exit button
The Hidden weight function can be disabled by
pressing the Hidden Weight.
Hidden Weight Programme is enabled even
when the operator inserts the wheel dimen-
sions manually (possible anomaly of one or
both lasers).
