9.0 SPLIT WEIGHTS - F92
The “Split Weight” function is used to split one large
weight to two smaller weights with 60% of original weight
and 33.6° away each direction from the original position.
For instance, if the original unbalance weight is 3 oz, the
weight is split into two 1.75 oz weights and placed 56.4°
and 123.6° from the original larger value located top dead
center at 90 degrees. The minimum weight to activate
this function is 2 oz. The procedure is described below.
See Figure 37.
1. After balancing, the weight amounts are displayed
in left and right windows.
2. Enter F92, machine will display “ SPL -L- “ or “ SPL
-R- “ meaning which plane should be split.
3. Press the “ STOP ” button alternately to toggle be-
tween the left and right plane.
4. Once the desired plane is chosen, press the "F"
button. The machine splits the weight into two parts.
The split weight is 60% of the original weight. The
position is 33.6° from each side the original posi-
tion.
5. If the displayed weight is less than 2 oz (56.7
grams), the machine will display “
NOT AVL ” for
one second, and then resumes the normal display.
6. Pressing “ STOP ” cancels the split weight mode
and operation returns to normal. The operator can
check if the position of original weight is between
the two smaller weights.
7. Pressing the “ STOP ” button again, returns the ma-
chine to idle mode without weight amount or posi-
tion display.
8. For a check spin, lower the hood guard or press
“
SPIN ” button.
