Operation
H2
Silent running cannot be improved.
However, it is possible to readjust the tyre relative to
the rim to achieve significant 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 === - OP.7
Turn the tyre over on the rim (the left display bars are
rotating).
Option 1: Turn the tyre over on the rim (adjustment
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 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 the main shaft.
•
Press the PRO-MATCH key (2) to acquire the valve
position.
Reading OP.8 appears.
•
Perform the check run.
If balancing optimisation 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 (3)
to exit the optimisation program and repeat optimisation
if necessary.
Option 2: Do not turn the tyre over on the rim
•
Press the F key (1).
The result is recalculated.
Reading OP.7 - = = = or H0 or H2 appears
•
To go to === - OP.7 (turning over the tyre) press the F
key again.
Option 3: Abort optimisation
•
Press the STOP key (3) 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.
