WHEEL SPIN AND
AUTOMATIC DIMENSION
MEASUREMENT
Wheel spin takes place automatically by lowering
the guard or pressing the Start button
with the guard lowered.
During the spin, the balancer, using the front and
rear laser sensors, will process the rim dimensions
using a special software for the final unbalance
calculation.
At the end of the spin, the rated dimensions of
the wheel are displayed in the feedback window,
specifically:
- The nominal rim width (only for dyn, sta, alu3,
alu4 and alu5 programs).
- The nominal rim diameter.
- The distance from the body to the inner edge
of the rim.
Note: at the end of the spin, if the automatic
position search function is enabled, the wheel
may spin with the guard raised.
NOTE
If the width measurement is highlighted in
red, it means that one of the automatic control
parameters has not been met and it is therefore
advisable to check the dimension. Using the
touch screen select, if necessary, the feedback
window and manually enter the nominal width
of the rim, press enter and exit the manual
entry mode.

NOTE
If the laser sensors fail to operate, the geometric
data can be entered manually by following the
procedure indicated in the "Manual wheel data
entry" section. This function is present in the Utility
and Configuration programmes.

NOTE
The laser sensors may not measure the rim
dimensions correctly on particularly reflective
surfaces. In this case enter the geometric data
manually following the procedure described in
the paragraph "Manual wheel data entry", which
is a function present in the Utility and Configura-
tion programmes.
CAUTION
bear in mind that the nominal wheel diameter
(e.g. 14") refers to the planes on which the tyre
beads rest which are obviously inside the rim.
On the other hand, the data measured refer to
external planes, so they will be lower than the
rated values because of the thickness of the
rim. The correction value therefore refers to
an average thickness of the rim. This means
that the data measured on wheels with differ-
ent thicknesses may vary slightly (2 or 3 tenths
of an inch maximum) from the rated values.
This is not a lack of accuracy of the measuring
devices, but reflects reality.
Do not operate the machine without the guard
and/or if the safety device has been tampered
with.
Never raise the guard before the wheel has
come to a stop.
If the wheel keeps spinning permanently due to
a fault on the machine, switch off the machine
using the main switch or disconnect the plug
from the power supply board (emergency stop)
