P ▪ ress : a window appears with the list of avai
lable USERS. The current user is displayed in red.
Press the number corresponding to the required USER.
▪
The system automatically returns to the initial screen
with recalculation of the unbalance values on the basis
of the effective dimensions of the USER called.
INDICATION
The dimensions memorized as USER are lost when the
machine is switched off. The USER control is also valid
for the ALUS dimensions.
The current USER is always displayed in the
Measurements and Dimensions screens.
5.4 RESULT OF MEASUREMENT
After performing a balancing spin, the unbalance values are
displayed as well as arrows useful for positioning the point of
application of the correction weight. After positioning of the
wheel, apply the weight in the 12 o’clock position. When the
beep signal is enabled ( ACOUSTIC SIGNAL ), reaching
of the correction position is accompanied by a “beep”. If the
wheel clamp option is enabled (
WHEEL LOCKING ),the
wheel is automatically clamped in the correction position. If
the unbalance is less than the chosen threshold value, the
“OK” appears instead of the unbalance value to indicate, on
that particular side, the wheel is in tolerance; the resi-dual
unbalance can be displayed by pressing button
with
an accuracy of 0.5 g (0.1 oz).
The following buttons are enabled:
Display of residual unbalance
Selection of correction mode (STATIC/DUAL
SURFACE). When the mode is changed, the
unbalance values are recalculated automatically
on the basis of the previous spin.
When this push button is held down for more
than 1.5 seconds, eccentricity measurement is
temporarily disenabled (enabled in SPECIAL
FUNCTIONS ). To re-enable eccentricity measure
Use of the wheel balancer
ment, press push button [4] again for more than
1.5 seconds. Every time the machine is switched
on, the status of eccentricity measurement refl ects
the settings in SPECIAL FUNCTIONS .
Split control for splitting of unbalance over preset
table components (
“SPLIT” CONTROL ). Button
only enabled in STATIC or ALUS correction.
Indication of the longitudinal position of the unba-
lance
( INDICATION OF EXACT CORRECTION
WEIGHT POSITION ) is enabled.
For selection of special functions
Balancing spin.
INDICATION
If the machine remains on this screen without being
used for more than the time preset in the Setup
parameters, the screen automatically returns to the
screen-save.
5.4.1 Indication of exact correction weight
position
It is possible use this function in the event of correction of
the external side using an adhesive weight placed inside
the rim. Remember to thoroughly clean the application
areas. This function allows cancelling approximations in the
mounting of counterweights with consequent reduction of the
residual unbalance.
From the measurement results frame:
▪ Press button from the Measurements screen.
▪ Pull out the rim distance+diameter gauge in position A,
fi gure in STANDARD WHEELS . Approach of the weight to
the correction position is indicated by a moving coloured
arrow [
].
▪ When a fi xed arrow [ ] is reached, rotate the wheel to
correction position (FI or FE) and apply the counterweight
by turning the tip of the gauge towards the outside, into
the position in which the pincers touches the wheel.
Compensation is made for the fact that the weight appli-
cation position is no longer at 12 o’clock (where appro-
