14.8 Special balancing programs
14.8.1 Pax
The PAX mode is a special procedure specially devised
to balance wheels using the “PAX System ®”. 2 adhesive
weights on different planes are used on rim inner side.
To launch a PAX measurement, proceed as follows:
- Make sure there are no stones and/or mud on the
wheel. Remove any counterweights. Fit the wheel and
make sure it is properly fastened (see Chapt. 12).
- Press
button from “Home” page. On the screen
that appears, press the programs icon to
switch to measuring mode selection screen below.
Press directly on the wished PAX mode icon in order
to select it.
At the end press push button
. The machine
will be configured as follows to perform the meas-
urement and on the video screen will appear the
indication of the specific measures of the selected
wheel type.
- Close the protection guard to perform the automatic
wheel spin.
In just a few seconds, the wheel runs at normal speed
and the monitor shows wheel rotation.
After the spin, the wheel stops automatically, taking
into account the measured unbalance so that the fitting
position of the weight will be at 12 o' clock.
The the monitor show the weight required to correct
the unbalance.
Open the protection guard and proceed to fit the
adhesive weight as shown for the ALU-S mode (see
Par. 14.6.5).
14.9 Recalculation Function
After making a spin, the wheel automatically stops,
indicating the weight/s to be fitted and its/their posi-
tion. In case the operator does not want the type of
wheel balance proposed by the machine (program type,
weights size, etc ...), proceed with the re-calculation
of the wheel balancing without rerunning the spin of
the wheel.
To do this, proceed as described below:
- press the button
to return to the measures
detection/program selection page;
- select a new balancing program as indicated in Par.
14.2.2;
- press button
to perform the re-calculation. The
monitor will display the weights and the positions in
which they will be applied.
If also in this case the operator should decide to fur-
ther modify the balancing program, it is sufficient to
proceed as described above without having to spin
the wheel.
14.10 Procedures for electronic RUN-OUT
measuring (tyre outer side) (Optional)
The GAR338 RUN-OUT electronic measuring device
(wheel eccentricity) is useful to check any roundness
defects in the wheel-tyre (ex: ovality and/or off-centre
as to the rim).
MAKE SURE THE ICON IN
THE OPTIONS MENU IS ENABLED
(SEE PAR. 15.1).
In order to display the tyre ovality screen page, proceed
as described hereafter:
- perform the wheel spin by closing the guard.
After executing the spin of the tyre with any kind of
program, the weights fitting page is displayed.
Here follows an example of the mentioned page:
By pressing the button (if on this screen page),
