ASF Alu Special Functions (ALU-6h, ALU-MAT, ALU-DIM)
for 16-bit wheel balancers

For a quality wheel balancing, good software can do a lot.
FASEP wheel balancers are equipped (1) with ASF (Alu special functions) for maximum accuracy when balancing ALU rims.

ASF functions are a FASEP exclusive design, for ease of use and maximum accuracy of balancing also when using adhesive weights on ALU rims.

ALU-6h (Stick-on at 6 o'clock)
Application of stick-on weights on ALU rims can be difficult because of the position of the weight at top-dead-center (12 o'clock).
With ALU-6h, the user can choose to place weights at 6 o'clock (bottom-dead-center) when needed.
6 o'clock is a convenient position for the user to apply the balancing weight as in that position it is easy to clean the rim and to place the weight in the exact position.

NOTE Obviously, Laser is always the preferred choice to ease this job!

ALU-DIM (Stick-on weights dimensions setup)

In case of stick-on weights for ALU rims, calculations of center of gravity are depending on weight width. A weight width that is different from the one written in the wheel balancer software may alter the weight position calculated by the computer and then result in measurements cross-talks from Inside to Outside and viceversa.
Since different weights manufacturers use different standards, balancing a wheel with stick-on weights is always more difficult then balancing a wheel with clip weights.
ALU-DIM let the user setup the wheel balancer for the specific width of adhesive weights used with the choice among 12, 15 and 19 mm width.
ALU-MAT (Balancing Materials)
With the new European regulations coming in place, the use of LEAD (Pb) on balancing weight has been banned.
Consequently, balancing weights are being manufactured using new materials such as Zinc (Zn), Iron/Steel (Fe) and Tin (Sn).
The density of the materials used instead of Lead (Pb) is quite different and this fact affects the dimensions of the weights. Weights in materials other then Lead are usually longer and larger.
Using the new weight on old wheel balancer may introduce a relevant error in calculations "center-of-gravity" of the weight especially in case of clip-weights.
With longer weights, the weight center-of-gravity position changes and consequently an error is introduced in the wheel balancer calculations.
ALU-MAT let the user setup the wheel balancer for the specific type of materials used, choosing among Zinc (Zn), Iron/Steel (Fe) and Tin (Sn).
In this way a more accurate balancing job is done with no extra spins or extra efforts!

 

Just another smart solution from FASEP!

 

(1)
ASF maybe optional on some models
Balatron 16-bit requires program version 2.4e or higher
Videotronic 16-bit requires program version 7.0 or higher
