4 - CONTROLS AND COMPONENTS
4.1 - BRAKE PEDAL
Fig. 5
This pedal allows the operator to hold the
wheel when fi tting the counterweights.
It must not be actuated during the
measuring cycle.
4.2 - PNEUMATIC LOCKING PEDAL (Version SE)
Fig. 6
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 specifi c 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 fi rst switch on, check the date and time
(see Clock set-up), adjusting them if necessary.
