8.5.2 SWI procedure at low speed

In the low speed SWI procedure, the wheel has already run the launch and is stationary. If the operator

presses [P8]

Start with the wheel guard raised, the machine will apply slight acceleration to the

wheel and then let the same 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.

Note:

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

8.5.3 Manual SWI procedure

In this mode, the SWI procedure is activated by manual rotation of the wheel if the wheel crankcase guard

is raised. 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. Among the most important, they are: wheel

dimensions and weight, adjustment of the electromagnetic brake, 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;

• In the automatic SWI procedure, the wheel must be heavy and large enough to provide the inertia required

for the running of this procedure. In case of particularly light and/or small wheels, the machine might not

run the SWI procedure and will use conventional braking;

• If rotation 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 ﬁ rst angular position of imbalance. If, despite this,

the wheel does not reach this position, the SWI procedure is aborted after 5 seconds and a triple beep

will signal this condition;

• When you use the manual SWI procedure, balancing precision will also depend on the speed with which

the operator rotates the wheel: excessively high or low speeds reduce accuracy.

9. SERVICE MODE

In this mode, the machine allows the user to enter certain settings (for example, selection of the units of

measure) or use special testing programmes (to verify machine functioning) or conﬁ guration.

Some test and conﬁ guration programmes are included in this Menu while the setting programmes

are available with direct access by means of the buttons. See table T9 to consult the full list of settings,

programmes and menus available in the SERVICE mode.

Note:

some test or conﬁ guration programmes are not available to the end user but only to technical support personnel.

To access the SERVICE mode, proceed as follows:

1. Switch the machine on and wait for completion of the initial test. After running the initial test, the

machine will be in the NORMAL mode;

2. Press [F+P3]

. The machine enters the SERVICE mode and will display the Ser Ser

messages. See ﬁ gure F9.1.
