INDICATION
when the acoustic signal is enabled ( ACOUSTIC
SIGNAL), the reaching of a fixed arrow [ ] is
accompanied by a “beep”.
5.4.2 “SPLIT” control
SPLIT is only possible in the event of static unbalance or
ALUS external side and is used to hide any adhesive weights
correcting unbalance behind the rim spokes.
To split the unbalance detected in two different positions,
proceed as follows :
Position static unbalance or ALUS external side in 1.
the correction position :
Select a spoke close to the 12 o’clock postion to be 2.
corrected, more it into the 12 o’clock position and
press button [6].
Turn the wheel in the rotation direction indicated on
3.
the unbalance display, brining the second spoke to
the 12 o’clock position and press button [6].
Turn the wheel in direction of rotation.
Turn the wheel in reverse direction of rota-
tion.
At this stage, the screen shows the graphic display 4.
of the correction spokes with the relative weight of
the unbalance detected.
Position the spokes indicated on screen in the 12
5.
o’clock position and correct with the value displayed.
Any error in this procedure is clearly shown on screen.
Always follow the information provided by the wheel to opti-
mise correction.
When SPLIT is enabled, the icon appears
on the left of the screen.
5.4.3 Automatic minimization of static unba-
lance
This program is designed to improve the quality of balancing
without any mental effort or loss of time by the operator. In
fact by using the normal commercially available weights, with
pitch of 5 in every 5 g, and by applying the two counterweights
which a conventional wheel balancer rounds to the nearest
value, there could be a residual static unbalance of up to 4
g. The damage of such approximation is emphasized by the
fact that static unbalance is cause of most of disturbances
on the vehicle. This new function, resident in the machine,
automatically indicates the optimum entity of the weights
to be applied by approximating them in an “intelligent” way
according to their position in order to minimize residual static
unbalance.
