Operation
The machine performs the second measuring run with
the tyre. After the measuring run three readings are
possible:
=== - Un.7
Proceed with the UN program. It is recommended that
the tyre be turned over on the rim.
Un.7 - ===
Proceed with the UN program. It is recommended that
the tyre be readjusted on the rim.
H0
The optimum minimisation condition has been achieved
and cannot be improved.
1 2
Depending on the readings, there are several
possibilities for proceeding with the program. These
possibilities are described below.
Reading === - Un.7
Turn the tyre over on the rim (the left display bars are
rotating).
Option 1: Turn the tyre over on the rim
(adjustmment 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 to acquire the valve
position.
Reading Un.8 appears.
- Perform the check run.
If weight minimisation was 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.
3
5.4.1-2
- Balance the wheel according to the readings.
Both weight minimisation and balancing are
accomplished.
Message E9
Message E9 means that at least one error occurred
during the minimisation cycle. Press the STOP key to
exit the minimisation program and repeat minimisation
if necessary.
Option 2: Do not turn the tyre over on the rim
- Press the F key.
The result is recalculated.
Reading Un.7 - = = = or H0 appears
- To return to === - Un.7 (turning over the tyre) press
the Fine key again.
