10. Auto-Orientation Mode / Sticky-On-Top
B9460 Specific Features
If C11 has been set to mode 1 or 2, the balancer will automatically brake to either the left or right weight
application position after a measuring run. Pressing and releasing the PLUS key will auto-orientate the
wheel into the weight application position for the other correction plane.
Rotating the shaft by hand following a measuring run will result in a motor pulse being generated when
the wheel is turned through either weight application position where the unbalance is greater than the
set threshold.
11. Split Weight Mode
The split weight mode is accessed via the star menu (see above). Upon selecting this mode "S1" or "S--"
is displayed in the right display panel. The left plane and its display panel are unaffected throughout this
function.
"S1" indicates that the first spoke can be selected in the present wheel position. Spoke positions are
entered at the 12 o'clock position. Spoke 1 can be +/- 120.0 degrees from the original outer plane weight
position. Spoke 1 is entered by pressing return.
"S2" or "S--" is now displayed similarly to before. Again, the return key is used to enter he second spoke
position.
The second spoke can be within 120.0 degrees of spoke 1, but must be on the "other side" of the original
weight position.
If the return key is pressed a number of times while "S--" is displayed (invalid spoke position) the
function exits.
Upon selecting spoke 2 the results are recalculated and displayed. The application position shown in the
weight bar incorporates the sape offset and the split weights must be applied with the sape (like all stick
on weights in HWM modes). The closest weight to the application position is that which is displayed in
the right display panel.
The function is exited by pressing the return key. A beep is generated and the original weight value is
displayed.
Split weight mode can also be exited at any time by starting a wheel spin.
SWM can only be selected from a HWM mode with an outer plane unbalance of 10 grams or
greater. SWM is always performed in low resolution mode (not fine mode) regardless of
whether fine mode is active prior to SWM selection.
