manually enter the values of the two dimension pairs
di1/da1
and
di2/da2
proceed as indicated in section 15.3.2 Entering wheel
size for Program Types ALS1, ALS2
. After the launch, the angular position of the balancing weights is specified in table T15.6.

ALS2 H6 H6 H6
To find the position along the rim section, remove the Distance sensor until you read the manually-set distance value
di1
or
di2,
on the graduated scale. At that point, you must take note of the plane identified by the sensor and apply the weight in the
angular position shown in table T15.6. In the case of Program Type ALS1, the
di1
position always corresponds to the rim internal
edge.
16. HIDDEN WEIGHTS PROGRAM
This program divides the external weight W into two weights W1 and W2 (smaller than the initial external weight W) located in either
of two positions selected by the operator.
The two weights W1 and W2 must form a maximum angle of 120° including the external weight W, as shown in Figure F16.1.
Figure F16.1 Hidden Weights Program: valid and invalid conditions for use. In this example, the external balancing weight W is
marked at 12 o'clock (H12), but it can also be marked at 6 o'clock (H6) or 3 o'clock (H3): see text
The Hidden Weights program is used for aluminum rims when:
•
You want to hide the external weight behind two spokes for aesthetic reasons.
• The position of the external weights coincides with a spoke, therefore a single weight cannot be applied.
NOTE: This program can be used with any Program Type and with any Wheel Type. It can also be used to divide the static weight into
two separate weights.
NOT VALID!
The angle between the two weights
W1 and W2 is ≥ 120 °.
NOT VALID!
External imbalance W is not within W1
and W2.
VALID
The angle between the two
weights W1 and W2 is < 120°
and includes the initial external
weight W.
