one plane only, or if the data of the outside plane have been acquired before those
of the inside plane, the message "Err 23" appears and the data entered are ignored.
- Carry out a spin.
Attaching balancing weights (ALU P= EASY ALU, fig.19)
- Select the plane where the first balancing weight is to be applied.
- Rotate the wheel until the central element of the corresponding position indicator is
illuminated.
If the balancing weight is of the traditional clip type (inside plane in ALU 2P= EASY
ALU 2), position the balancing weight at 12 o'clock. If, on the other hand, the weight is
of the adhesive type:
- position it inside the cavity in the weight holder end of the measuring arm (A, fig.
19), with the backing paper of the adhesive strip facing up. Then remove the backing
paper.
- Move the sensor until it is in the position indicated. In this phase, one display
continues to show the imbalance value of the side to be balanced, while the other
shows a numerical value updated on the basis of the sensor position, which becomes
zero when the position for application of the weight is reached.
- Rotate the end of the sensor until the weight adhesive strip is in position in
correspondence with the rim surface.
- Press the push button (C, fig. 19) to eject the weight and make it stick to the rim.
- Return the sensor to the rest position.
- Repeat this process for the application of the second balancing weight.
- Carry out a test spin to check the accuracy of the balancing.
In order to be sure that the weight sticks to the rim the surface must be perfectly clean.
If necessary, clean the rim surface with a suitable detergent.
"Shift planes" program (only available with ALU P= EASY ALU programs)
This function is automatically activated when an ALU P= EASY ALU program is
selected.
It modifies the positions chosen for application of the adhesive weights in order to
allow the wheel to be perfectly balanced using commercially available adhesive
weights. This means that the balancing weights to be fitted to the rim will always be
multiples of five grams for car wheels and multiples of fifty grams for truck wheels.
This means there is no need to round the weights to be applied up or down or to
cut them to come closer to the real imbalance values. The result is a significant
improvement in balancing precision.
Normally the machine modifies the weight application positions on the basis of criteria
preset by the program.
(only available on demand with ALU P= EASY ALU programs)
This program sub-divides the outside balancing weight into two combining weights,
located in a hidden position behind the two spokes on the aluminum rim.
- First select either the ALU 1 P= EASY ALU 1 or the ALU 2 P= EASY ALU 2 program.
