"Movable planes" program
This function is automatically enabled when an ALU P program is selected.
It modifies the selected positions for the application of adhesive weights, so as to ensure perfect
balancing of the wheel using commercially available adhesive weights (i.e. multiples of five grams).
The accuracy of the machine is thereby improved, avoiding rounding off or cutting the weights to be
applied to come closer to the actual unbalance values.
The modified positions, where the adhesive weights are to be applied, are identified by the user according
to the information given by the wheel balancer (see the BALANCING WEIGHT APPLICATION section).
This programme divides the outer weight Pe into two weights P1 and P2 located in any position chosen
by the operator.
The only condition is that the two weights and the original outer weight Pe must be within an angle
of 120°, as shown in fig. 23.
Fig. 23. Conditions for using the Hidden Weights programme
The Hidden Weight programme is to be used on alloy rims, only and exclusively in conjunction with
the ALU1P/ALU2P programme, when:
- when the outer weight would rather be hidden behind two spokes for aesthetic reasons;
To use this programme, proceed as follows:
1. Select either ALU1P or ALU2P before starting. by selecting the ALU 1P Balancing programme icon or the
ALU 2P Balancing programme icon. The mask for measuring the unbalance on alloy rims is displayed.
2. Perform the wheel balancing procedure as described in the chapter "ALU1P, ALU2P Programmes",
but without applying the outer weight.
3. Select the Hidden weight icon. If the wheel is balanced on the outer side, the machine displays the
message shown in Fig. 24b on the screen.
