OPTIMIZATION/WEIGHT MINIMIZATION
Balancing optimization program cycle
The following is a description of the balancing
optimization program cycle (code OP) and weight
minimization (code UN).
Balancing optimization
Figure 32
If after the measuring run the imbalance in the left or
right correction plane and/or the static imbalance is
more than 30 grams, perform automatic optimization
by activating the
MODE
+
ENTER
key (
3
+
1
).
•
Before optimization check that the rim dimensions
have been set correctly.
You cannot correct the data later.
•
Demount the tire and clamp only the rim for the
compensation run.
•
Press the
ENTER
key (
1
).
The
OP.1
reading appears
(
Fig. 33
)
.
In all fi gures in which the valve symbol appears on the
edge of the rim, shift the tire on the rim then press
the
ENTER
key (
1
) to set the valve position (exactly
perpendicular to and above the main shaft).
•
Readjust the rim so that the valve is exactly
perpendicular to and above the main shaft.
•
Press the
ENTER
key (
1
) to acquire the valve
position.
The
OP.2
reading appears.
An incorrect valve position entry can be corrected
afterwards.
Weight minimization
If no optimization, but only weight minimization (i.e.
without compensation run for the rim without tire),
proceed as follows:
•
Clamp the complete wheel (rim and tire).
•
Press
FINE
(
3
)
+
ENTER
key (
1
) if minimization is
started separately from optimization.
The
OP.1
reading appears.
•
Press the
MODE
key
(
3
)
to activate the weight
minimization program.
The
Un.3
reading appears;
Run the minimization program.
•
With program
OP.2
the rim compensation run can
still be omitted. Go to the next step in the program
by pressing the
FINE
key
(
3
)
.
The
UN.4
reading appears.
•
Continue the minimization program.
The valve position entered with
OP.1
is automatically
used.
