Operation
•
Spinn the wheel
(START
).
After the measuring run four readings are possible:
II - OP.7
Proceed with the OP program. It is recommended that
the tyre be turned over on the rim.
OP.7 - II
Proceed with the OP program. It is recommended to
shift the tyre on the rim (manual rotation).
H0
Optimum condition has been achieved and cannot be
improved.
H2
Silent running cannot be improved.
•
Press
STOP
(
5
) to exit.
However, it is possible to readjust the tyre relative to
the rim to achieve signifi cant weight minimisation (i.e.:
smaller balance weights) without having an adverse
effect on silent running.
Depending on the readings, there are several
possibilities for proceeding with the program. These
possibilities are described below.
Reading
II - OP.7
(
Fig. 5-37
)
Turn the tyre over on the rim (the left display bars are
rotating).
Option 1:
Turn the tyre over on the rim (normal
program).
•
Readjust the wheel according to the left direction
indicator and make a double mark on the left side
of the tyre exactly perpendicular to and above the
main shaft.
•
Remove the wheel from the machine.
•
Turn the tyre over on the rim and readjust until the
double mark coincides with the valve.
•
Clamp the wheel on the balancer and readjust it so
that the valve is exactly perpendicular to and above
the main shaft.
•
Press the
ENTER
key
(
1
)
to acquire the valve
position.
Reading
OP.8
appears
(
Fig. 5-34
)
.
•
Spinn the wheel
(START
).
If balancing optimisation (silent running) has been
carried out correctly (according to the program cycle),
after the check run the machine automatically returns to
the type of weight positioning previously selected and
indicates the residual dynamic imbalance on the wheel.
•
Balance the wheel according to the readings.
Both optimisation and balancing are accomplished.
Message
E9
Message E9 means that at least one error occurred
during the optimisation cycle. Press the
STOP
key
(
5
)
to exit the optimisation program and repeat
optimisation if necessary.
