9.2 OPTIMA ENTRY Screen
(fig. 9.2-0)
Press
F6 in the balancing screen to access.
The control software automatically displays this screen
whenever, at the end of the wheel measuring run, the
measuring values exceed the preset limits.
The overall wheel (rim + tire) measuring run is displayed.
To move the cursor on the wheel graph, rotate the wheel
by hand in both directions.
All of the OPTIMA ENTRY screens show the first
harmonic Peak index (1, fig. 9.2-1), which facilitates
advanced diagnosis of the rim or the wheel.
The unbalance data is shown under the graph (first runout
harmonic).
The automatic Position Brake fitted on the machine will
be activated when the peak position is manually brought
to the 12 o'clock point.
The Position Brake function can be temporarily disabled
in two ways:
- In the BALANCING or OPTIMA ENTRY screens press
the STOP key once to disable, press it a second time
to re-enable the function.
- The brake is not activated if the "Rim Cleaning Position
Brake Control" function has been activated in the
FUNCTIONS menu.
a) Wheel radial runout.
b) Rim radial runout (if measured).
c) Rim lateral runout (if measured).
d) Runout proportion due to rim or tire.
e) Equivalent static unbalance estimate given by the
runout at 100 km/h.
f) Describes the performance improvement if the
geometric matching is applied.
g) Runout value at the position the graph cursor is
in, which corresponds to the wheel at 12 o’clock.
h) Peak to peak (p-p) graph; the peak to peak value
is the difference between the maximum and
minimum value.
i) Preset threshold on the wheel runout.
k) Warning of defective rim and/or tire. The software
prompts the operator to check for rim or tire
defects, suggesting
matching or automatically
showing the screen for the appropriate corrective
action, where necessary.
If defects are found, box “j” may display from one to
three Warning Messages (Section 9.2.1). Each
message may indicate two levels of seriousness,
as follows:
For measurements above the limit value, a Problem
indication is displayed.
For measurements straddling the limit value, the
Possible Problem indication is displayed.
