Behind–the–spokes
Hidden Weight Mode
placement (
When spoked wheels are balanced, the behind–the–
spokes placement mode (also called split weight
mode) allows balance weights which would have to be
fitted 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 menu key F5 in the screen BALANCING.
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 F5 (Fig. 5-27) is
only active after the number of spokes have been
entered using the F1 menu key.
How to proceed
After this run, in the BALANCING screen:
Use the F1 (Fig. 5-27) menu 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 F1 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 centred
relative to and above the main shaft (Fig. 5-28,
arrow).
