3.3.5 Use of the Special Programme Types for ALS1 and ALS2 aluminium wheels
The machine features two Special Programme Types for aluminium wheels called ALS1 and ALS2.
These two programmes are different from the normal Programme Types for aluminium wheels (from ALU1
to ALU5) because they allow the user to select the planes on which apply the balancing weights. This allows
balancing aluminium wheels with special rim confi gurations where the use of conventional programmes
for aluminium, which require precise weight positioning, would result diffi cult.
The difference between the ALS1 and ALS2 programmes lies in the fact that in the ALS1 Programme Type the
user can freely choose only the external balancing plane (the internal plane is in a predetermined position)
whilst, in the ALS2 Programme Type, the user can freely choose both balancing planes.
The ALS1or ALS2 Programme Types use only the Distance/Diameter sensor to acquire the balancing planes
chosen by the user. The Width sensor is not used.
Use of the ALS1 or ALS2 Programme Types is divided into three parts:
• acquisition of balancing planes;
• balancing launch;
• search of the balancing planes for weight application.
3.3.5.1 Acquisition of the balancing planes
The two balancing planes are acquired at this stage. During acquisition, the two pairs of distance and diameter
values are stored. These pairs are called di1 and da1 (distance 1 and diameter 1) for the internal plane
and di2 and da2 (distance 2 and diameter 2) for the external plane.
Once acquisition is completed, you can view (and even edit) these two pairs of values by pressing [P1]
q
for the distance and [P3]
(
for the diameter.
By pressing [P1]
, the displaying of the distance values di1 and di2 are alternated. By
pressing [P3]
, the displaying of the diameter values da1 e da2 are alternated.
To carry out acquisition, proceed as follows:
1. Select the ALS1 or ALS2 Programme Type by repeatedly pressing [P4]
or [P5] ;
