voltage(s) change. The distance from the balancer to the wheel is generated from the voltage output and the diameter
of the wheel is generated from the amount of voltage output when the arm is moved up. Adjustment are made using
the C80/C81 service code, this procedure can be found later in this manual.
3.20 SONAR WHEEL DATA SYSTEM
The sonar sensor device is used on some ranges of balancers
to read the rim width. The sonar is a detector of distance and
detect a possible return echo generated by the presence of an
object within the nominal fl ow.
On the wheel balancer the sonar must work in conjunction with the inclination of the wheel guard, rim offset and
diameter.
This because it must make a board of returned echo signals to be converted through a specifi c trigonometry
recalculation, to the rim width.
3.21 SONAR SENSOR
The Sonar Sensor is used to detect all information required by the IBP about
the rim to make rim width measurement.
The present sonar is of digital type and it is equipped by an electronic
inclinometer to avoid the using of the wheel guard potentiometer.
The Sonar Sensor, old and new, are not reparable and can be replaced
separately from the scanner.
