Operator’s manual
Keep the
keys pressed to rapidly increase or decrease the previously
set values.
After completing the wheel data update, press the
button to exit and display the
unbalance values recalculated according to the new dimensions, or to perform a wheel spin.
- if two subsequent measurements are taken inside the rim on two balancing planes, the
machine interprets the presence of a rim with balancing using a clip weight on the inner
plane and an adhesive weight on the external one (ALU 2P).
In this phase, the machine could automatically change the type of weight on the inner
plane from clip to adhesive (ALU 1P). The operator is able to change this setting by press-
ing the
or
key. In this case, the balancing programme switches from ALU
1P to ALU 2P and vice versa.
Wheel data entry for wheel balancers with an ultrasonic sensor
(if installed)
To enter the distance, diameter and width values automatically, proceed as follows:
- Bring the internal automatic measuring arm into contact with the inner side of the rim
(fig.11). During this phase, the graphic shown in figure 11a will appear on the display.
Take great care to position the arm correctly so as to ensure accurate data reading.
- Keep the arm in contact with the rim until the machine has acquired the wheel's diameter
and distance values. During this phase, the graphic shown in figure 11b will appear on
the display.
- If only one measurement is taken, the machine interprets the presence of a rim with
balancing using a clip weight (Dynamic Balancing Programme).
- When the automatic internal measurement arm returns to the rest position, “Lr” will
appear automatically on the left display and the type of wheel will be shown on the
right display:
- P (Passenger Tyre) for medium sized wheels (wheels with a tyre shoulder that does not
protrude much from the rim);
- Lt (Light Truck Tyre) for large sized wheels (such as off-road, trucks or wheels with a tyre
shoulder that protrudes considerably from the rim).
- Use the key
to select the type of wheel in use.
- If you press the
button in the phase indicated above, the width can be entered
manually using the keypad.
