guard raised.
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.
19.4.1 Automatic SWI procedure
During the automatic SWI procedure, the machine will measure rotational speed during braking at completion of the spin 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.
19.4.2 SWI procedure at low speed
In the low speed SWI procedure, the wheel has already run the spin and is stationary. If the operator presses [P8] key Start
with the wheel guard raised, the machine will apply slight acceleration to the wheel and then let it spin 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.
19.4.3 Manual SWI procedure
In this mode, the SWI procedure is activated by having the operator manually rotate the wheel. When the wheel passes through an
angular position of imbalance, the machine will enable the electromagnetic clamping brake.
Angular positioning accuracy depends on many factors. The main ones being: wheel dimensions and weight, electromagnetic brake
adjustment, temperature, belt tension. In all cases, consider the following:
If the electromagnetic clamping brake is disabled, the SWI procedure will not be run in any of three modes;
If revolution speed decreases abruptly due to wheel inertia during the automatic SWI procedure or the low speed SWI
(e.g. due to excessive friction with rotating mechanical parts) the machine applies a little extra acceleration to the wheel
itself in order to reach the first angular position of imbalance. If, despite this, the wheel does not reach this position, the
SWI procedure is aborted after 5 seconds and the machine displays the error code Err 042;
When using the manual SWI procedure, precision also depends on the speed that the operator turns the wheel at:
excessively high or low speeds reduce precision.
19.5 Rotation at low speed to run a visual control of the tyre/rim
The machine has a LOW SPEED PROGRAM to decrease shaft revolution speed to perform a visual check on the tyre on the rim.
To start the program press [F+P4]
.
Press [P4]
and [P5]
to increase or decrease shaft revolution speed within a range of 4 ÷ 50 RPM.
20. “SERVICE” MODE
In this mode, the machine allows the user to enter certain settings (for example, selection of the units of measurement) or use
special testing (to check the machine operation) or configuration programs.
Some testing and configuration programs are included in Menus while setting programs are available with direct access via buttons.
See table T13.2 for the full list of settings, programs and menus available in SERVICE mode.
