5.9 Behind–the–Spokes Placement
(Split Weight Mode)
When spoked wheels are balanced, the behind–the–
spokes placement mode (also called split weight
mode) allows balance weights which would have to be
fi tted between two spokes according to the measured
unbalance (hence would be visible from outside) to be
placed in hidden position behind two spokes adjacent
to the unbalance location (see example, Fig. 5-26).
After a measuring run the electronic unit 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.
5.9.1

Selecting the Hidden Weight Mode

The behind–the–spokes placement mode is activated
with the key (17,Fig.5-27) 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 is only active
after the number of spokes have been entered using
the 19 key.

How to proceed

After this run, in the BALANCING screen:
— Use Spoke selection (19,Fig. 5-27) to select the
number of spokes in the wheel on the machine (if
not already entered). Each time the key is pressed
increases.
The key 19 displays the indication:
- number of spokes set.
The number of spokes can vary from 3 to 12.
— Rotate the wheel so that a spoke is centered
relative to and above the main shaft (Fig. 5-28,
arrow).
