• Weights fitting at “6 o'clock”.
TO USE THIS MODE, THE REL-
EVANT FUNCTION MUST BE ENA-
BLED ON THE MENU USER - PA-
RAMETERS CONFIGURATIONS
- PARAMETER 9 (PAR. 20.4).
TO USE THIS WEIGHT APPLICA-
TION MODE THE OPERATOR
MUST REMEMBER THE PRECISE
POINT WHERE THE MEASURE-
MENT WAS TAKEN WITH THE
DISTANCE-DIAMETER CALIPER
ARM.
USING THIS MODE, THE MACHINE
ALLOWS YOU TO APPLY ANY AD-
HESIVE WEIGHTS AT "6 O'CLOCK".
AFTER YOU ENABLE THIS MODE,
THE PROGRAMS WITH FIXED LED
ON THE RESULTS PAGE WILL
REQUIRE THE FITTING OF THE
WEIGHT AT “12 HOURS”.
At the end of the spin, the wheel stops in place to
apply the weight at "6 o'clock". The positioning of
the weight (s) in depth shall be at the discretion of
the operator, depending on where remembers taking
the measure.
MAKE SURE TO FIT THE WEIGHT
(INNER OR OUTER) AS INDICATED
BY THE FLASHING LED ON THE
RIM SHAPE GRAPHICAL DISPLAY-
ING.
BEFORE REMOVING THE DIAME-
TER-DISTANCE CALIPER, PRESS
THE BRAKE PEDAL AND HOLD IT
DOWN UNTIL THE WEIGHT HAS
NOT BEEN APPLIED, ENSURING IN
THIS WAY THAT, DURING THESE
PHASES, THE WHEEL CAN NOT
ROTATE.
14.3.3 Dynamic balancing
Dynamic balancing is a procedure that offsets the
wheel vibrations using 2 weights on different planes.
Clip weights are used on rim inner/outer edge, and
usually on iron rims.
To perform a dynamic measurement spin:
- 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 Chap. 12.0).
- Enter the wheel measurements (see Par. 14.1).
- Close the protection guard to perform the automatic
wheel spin.
In just a few seconds, the wheel runs at normal speed
and the display screens D1-D2 show wheel rotation.
After the spin, the wheel stops automatically, also tak-
ing into account the measured unbalance so that the
fitting position of the outer weight is exactly at “12
o’ clock”.
Open the protection guard.
Display screens D1-D2 show the weight required to
correct the unbalance. The nearby LEDs show the
direction the wheel has to be moved into to fit the
weights (Fig. 30).
Weight can be determined in "grams" or "ounces"; in
this manual examples are shown in grams. To change
the unit of measurement from "grams" to "ounces",
(see Chap. 20).
Once the unbalance of the inside and outside of the
wheel is known, it is possible to proceed with position-
ing for correction of unbalance.
Should wheel dynamic unbalance be quite high and the
weight to be fitted not available, the “SPLIT” procedure
can be used so as to correct the dynamic unbalance
dividing the weight amount into two smaller weights
(see Chap. 16).
