8.4 Behind–the–spokes placement
When spoked wheels are balanced, the behindthe
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. 8-16).
After a measuring run the electronic unit calculates the
behindthespokes placement automatically and reads
the relative balance weight locations on the screen.
The operating steps for the behindthespokes placement
mode are described and illustrated below.
8.4.1 Selecting the Hidden Weight Mode
The behindthespokes 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 is only active after
the number of spokes have been entered using the F5
menu key.
How to proceed
After this run, in the BALANCING screen:
• Use the F5 menu to select the number of spokes in
the wheel on the machine (if not already entered) (Fig.
8-19).
The Status Bar field 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 centred relative
to and above the main shaft (Fig. 8-18, arrow).
Note:
We suggest you keep the wheel in position with the
brake pedal until the selection has been made.
• Use the F5 menu key to select the Hidden Weight
behind spokes item (1,Fig. 8-17).
The function is now selected and on the right of the screen
two balancing gauges are shown instead of one.
• Proceed, if necessary, with Optimisation/Minimisation, or
apply the compensation weights directly (Chapter 9.3)
