Operation
5.15.4 Behind–the–spokes placement -
SWM (Split Weight Mode)
The behind-the-spokes placement mode (SWM) allows
to split balance weights that, according to the machine,
would have to be fitted in a visible position that probably
the customer would not like.
With the SWM Mode instead, two weights, equivalent
to the first one, are placed behind the closest spokes
(see example, Figure 5-57).
After a measuring run the electronics calculates the
behind–the–spokes placement automatically and
reads the relative balance weight locations on the
screen.
The operating steps for the behind–the–spokes
placement mode are described and illustrated below.
5.15.4.1 Selecting the Split Weight Mode
The behind–the–spokes placement mode is activated
with key (17,Fig. 5-58) in the BALANCING screen.
Weights can be positioned behind the spokes in the
Alu 2, Alu 2P, Alu 3 and Alu 3P (hidden compensation
weight) balancing modes and can be selected in these
spheres as required.
Note: The "Hidden Weight" selection key (17,Fig. 5-58)
is only active after the number of spokes have
been entered using the key (19,Fig. 5-58).
How to proceed
After this run, in the BALANCING screen:
 Use key (19,Fig. 5-58) to select the number of
spokes in the wheel being processed (if not already
entered). Each time the key is pressed there is an
increment.
The Key field (19,Fig. 5-58) displays the indication:
number of spokes set.
The number of spokes can vary from 3 to 15.
 Rotate the wheel so that a spoke is perpendicular
to and above the chuck shaft (Figure 5-59, arrow).
