Operation "PROFILING"
5.5.1 Wheel measuring run (PROFILING)
•
Lower the wheel guard from the fully raised position.
Pull the guard smoothly at medium speed, without
stops or jerking even to the side.
Note:
You must be very careful when lowering the guard,
as the machine simultaneously scans the wheel
external rim profi le.
If you lower the wheel guard incorrectly:
the machine immediately indicates the incorrect
manoeuvre, showing a specifi c warning icon on the
screen. See Fig. 5-32.
The message is cleared
- automatically after a few seconds
- when you reopen the wheel guard
- when you press the STOP key or the ESC key
If you decide not to repeat wheel guard lowering, you
can press START to continue with the measuring run.
In this way the wheel width is not automatically
detected by the sensor and the machine uses the
last value saved. To check the width present press
"Profi ling" (1, Fig. 5-33) and select RIM DATA INPUT.
The width value is shown in red, indicating that it was
not detected automatically.
If necessary you can set the width manually before
proceeding. If you enter the value manually the
machine will supply the balancing data correctly but
some recalculation functions will not be possible.
If you lower the wheel guard correctly:
- With the PROFILING MEASURING RUN NOT
ACTIVATED,
no signal appears on the screen, therefore to proceed
with the run
•
press the START button.
The balancer performs the measuring run with the
unbalance measuring cycle and rim profi le detection
(to fi nd the type, steel/aluminium and count the spokes,
if present).
At the end of the run, the unbalance values and the
points where the balancing weights should be applied
are displayed.
Select RIM DATA (1, Fig. 5-33) to check the rim
nominal dimensions.
Directly press the grey-coloured weights, located on
the rim profi le, to set the desired ALU mode.
Alternate the type of ALU by selecting it from those
suggested. The Menu contains only the ALU that the
machine retains possible, based on the type of rim
detected.
