Wheel Spin And Position Search - Mondolfo Ferro MT 3800 LASER Manual De Uso

- in this phase, it is possible to perform a new
acquisition of the rim planes.
- lowering the guard confirms the selection that
was made (manual width entry or wheel type
selection) and the width scanning and spin are
performed.
Note:
- automatic width acquisition is re-enabled
only with a new acquisition of the automatic
internal measuring arm;
- if the wheel guard is closed or in the case of
a fault of the sensor located on the guard,
the machine will automatic setup for manual
width entry when the internal measuring arm
is moved to the rest position;
- at the end of the spin, it is possible to change
the width acquired automatically by the ma-
chine by selecting the following icon on the
work page :
IMPORTANT
bear in mind that the wheel's rated diameter
(e.g. 14") refers to the planes on which the
tyre beads rest, which are obviously inside the
rim. On the other hand, the data measured
refer to external planes, so they will be lower
than the rated values because of the thickness
of the rim. The correction value therefore
refers to an average thickness of the rim.
This means that the data measured on wheels
with different thicknesses may vary slightly
(2 or 3 tenths of an inch maximum) from the
rated values. This is not a lack of accuracy of
MT 3800 LASER - Operator's manual
the measuring devices, but reflects reality.
If the automatic measuring arm fails to operate,
the geometric data can be entered manually
by following the procedure indicated in the
"manual wheel data entry" section, function
present within the utility and configuration
programmes.
WHEEL SPIN AND POSITION
SEARCH
Wheel spins take place automatically by
lowering the guard or pressing the start button
with the guard lowered.
A special safety device stops rotation if the
guard is raised during the spin; in this case,
the A Cr message is displayed.
During position search, the wheel can rotate
with the guard raised. Every time the start
button is pressed
position of one side switches to the centred
position of the other.
This function is active only if the RPA program
is set to ON (see "RPA - Automatic position
search configuration", function present in the
configuration programs).
WARNING
Do not operate the machine without the
guard and/or if the safety device has been
tampered with.
WARNING
Never raise the guard before the wheel has
come to a stop.
WARNING
If the wheel keeps spinning permanently due
to a fault on the machine, switch off the ma-
chine using the main switch or disconnect the
plug from the power supply board (emergency
stop) and wait until the wheel stops before
raising the guard.
