Operation
5.8 Preliminary verifi cations
Preliminary operations:
– If necessary, perform a compensation run (C4
7.1.1).
– Check the wheel is clamped correctly (
– Read the rim dimension parameters (
5.8.1 Measuring unbalances
Having completed the preliminary operations, a
Measuring run can be launched:
Wheel run - AUTOMATIC
— Starting from the completely lifted position, lower
the wheel guard at medium speed, without stops
or jerks even to the side.
Note: You must be very careful when lowering
the guard, as the machine simultaneously
measures the width on the external wheel
(Sonar).
After measurement the balance weights can be fi tted
or a weight minimisation or optimisation run can be
carried out.
The display shows the unbalance measured for
each correction plane and the rotation direction for
positioning.
5.8.2 Result recalculation
After the wheel measuring run, it is possible to change
wheel dimensions and select different positions for balance
weights. New unbalance values will be automatically
displayed, according to the inputs.
For recalculation:
• Select the preferred application method. Check if the
rim or offset plane data must be modifi ed.
• Rotate the wheel to the WAP position of left plane
and apply the weight.
• Rotate the wheel to the WAP position of right plane
and apply the weight.
• Start a check run.
