To turn on the illuminator, press [F+P9] . To turn off the illuminator, press [F+P9]

again.

The illuminator is also automatically managed by the machine that turns it on in the following cases:

• When the Distance/Diameter sensor is extracted;

• After a wheel stop procedure on the position of imbalance (SWI procedure) which resulted in the balancing

position of the internal weight;

• When the wheel itself is in the balancing position of the internal weight by manually rotating the wheel

after a launch;

8.5 SWI wheel stop procedure on the positions of imbalance

Machines equipped with the electromagnetic clamping brake are capable of automatically stopping the

wheel at the ﬁ rst imbalance angular position that is reached during rotation. This allows the operator to

have the wheel in position ready for the application of the balancing weight thus increasing work and

productivity speeds.

The procedure is referred to with the short English acronym SWI (Stop the Wheel on Imbalance). Within

this manual, this acronym will be used to refer to the wheel stop procedure on the positions of imbalance.

The SWI procedure has three different operating modes indicated in table T8.2.

Table T8.2 Types of SWI procedures available.

Notes

Automatic At the end of every launch Machine

This is performed only if there is at least

one imbalance value on the wheel. Other-

wise, conventional braking will occur.

Low speed

At the end of the launch,

when the wheel is stationary

and the wheel guard is raised

Operator

Procedure started by pressing [P8]

Start: the wheel starts spin-

ning at low speed until the ﬁ rst angular

position of imbalance is reached.

Manual

At the end of the launch by

manually rotating the wheel

with wheel guard raised

Operator

At each passage of the wheel in an

angular position of imbalance, the

electromagnetic clamping brake will

be enabled for 30 seconds.

The three SWI modes have functions that are slightly different one from the other although, in all modes, the

ultimate goal is to block the wheel at an angular position of imbalance and make operators’ tasks quicker.

8.5.1 Automatic SWI procedure

During the automatic SWI procedure, the machine will measure rotational speed during braking at completion

of the launch and, when this reaches a predetermined value, it will release the brake allowing the wheel to

spin freely by inertia. When the speed is low enough, the machine will wait until the wheel passes through

one of the angular positions of imbalance, therefore, it will enable the electromagnetic clamping brake.

Note:

for operator safety purposes, the SWI procedure will not be run when the MOTO Wheel Type is enabled.
