Activate the ILLUMINATOR DISABLING program by selecting
.
The illuminator is also automatically manage 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.
21.5 SWI wheel stop procedure on the positions of imbalance (only on MEC 820VD)
Machines equipped with the electromagnetic clamping brake are capable of automatically stopping the wheel at the first 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 T21.2.

Notes
Automatic
At the end of every launch.
Machine
This is performed only if there is at least one
imbalance value on the wheel. Otherwise,
conventional braking will occur.
Low speed
At the end of the launch, when
the wheel is stationary and the
wheel guard is raised.
Operator
The procedure is started by pressing [P8] Start
: the wheel starts at low speed until it reaches
the first imbalance angular position.
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 operator’s tasks quicker.
21.5.1 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.
