However, it is possible to readjust the tire relative to
the rim to achieve signifi cant weight minimization (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. 37
)
Turn the tire over on the rim (the left display bars are
rotating).
Option 1:
Turn the tire 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 tire exactly perpendicular to and above the
main shaft.
•
Remove the wheel from the machine.
•
Turn the tire 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. 34
)
.
•
Spin the wheel
(START
).
If balancing optimization (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 optimization and balancing are accomplished.
Message
E9
Message E9 means that at least one error occurred
during the optimization cycle. Press the
STOP
key
(
5
)
to exit the optimization program and repeat optimization
if necessary.
Option 2:
Do not turn the tire over on the rim
•
Press the
FINE
key (
3
).
The result is recalculated.
Reading
OP.7 - II
or
H0
or
H2
appears
•
To go to
II - OP.7
(turning over the tire) press the
FINE
key (
3
) again.
Option 3:
Abort optimization
•
Press the
STOP
key (
5
) to exit the OP program and
return to the balancing program.
The imbalance on the wheel is shown on the readout.
•
Balance the wheel according to the readings.
Reading
OP.7 - II
(
Fig. 37
)
Readjust the tire on the rim (the right display bars light
up permanently).
