4 - Controls and components
4.1 - Brake pedal
This pedal allows the operator to hold the
wheel when fitting the counterweights.
It
must not be actuated during the mea-
suring cycle.
4.2 - Pneumatic locking pedal (SE Version)
This pedal allows releasing the device
fastening the wheel on the adapter.
Do not
actuate this pedal during the machine
cycle and/or when adapters other than the
standard cone adapter are mounted.
The pedal has two stable positions:
top, wheel unclamped; bottom, wheel
clamped.
4.3 - Automatic distance and diameter gauge
This gauge allows measurement of the distance of the wheel from the machine and the wheel diameter at the point of
application of the counterweight. It also allows correct positioning of the counterweights on the inside rim by using the
specific function (see
INDICATION OF EXACT CORRECTION WEIGHT POSITION ) which allows reading, on the monitor,
the position used for the measurement within the rim (For calibration, see the corresponding section).
The gauge can only be used with the counterweight pincers mounted.
4.4 - Automatic width gauge (optional)
Width gauging is through a SONAR device which measures the distance of the wheel without mechanical contact,
merely by closing the guard and each time a valid measurement has been made with gauge
AUTOMATIC DISTANCE
AND DIAMETER GAUGE .
4.5 - Automatic wheel positioning
At the end of the spin, the wheel is positioned according to the unbalance on the outside or else according to the static
unbalance (when selected).
Accuracy is ± 20 degrees.
4.6 - Clock control
The wheel balancer is provided with a clock having a back-up of about one month with the machine switched off. If the
machine remains off for a long period, at the first switch on, check the date and time (see
CLOCK SET-UP ), adjusting
them if necessary.
4.7 - Printer (option)
Used to print useful information for the vehicle, residual imbalance and eccentricity for the balanced tyre.
