CONFIGURABLE FUNCTIONS
Two strategies can be used to calculate the bulk height:
Center point: The point on the bulk contour
which is vertical to the Bulkscan (0° angle)
is used.
Highest point: The point on the bulk contour
with the smallest distance to the Bulkscan
is used.

Fig. 4: Bulk height
The bulk height is the distance between this point and the conveyor belt.
The Bulkscan can monitor the bulk height and signal a violation of the control range on
a digital output.

How to congure the calculation of the bulk height:
 Switch to the Measurement tab.
 Select the required Strategy.

How to congure the signaling of the bulk height on a digital output:
 Switch to the Interfaces tab.
 Click on Digital outputs to open the Digital outputs tab (see "4.13 Digital outputs“
on page 25).
 Select the assignment Bulk height for the required digital output.
 Select the required Logic.
 DenetheLower limit, the Upper limit, and the associated Hysteresis.
How to congure the signaling of the bulk height on an analog output:
 Switch to the Interfaces tab.
 Click on BAM 100 to open the BAM 100 tab (see "4.14 Analog module BAM100“ on
page 26).
 Select the assignment Bulk density for the required output.
 Denethe4 mA point and the 20 mA point.
4.8 Monitoring the center of gravity
The Bulkscan determines the position of the center of gravity of the bulk from the bulk
contour. This enables tilted belts to be detected and prevents malfunctions in the case
ofunsymmetricalbeltllingorunevenmassdistribution.
The value for the position of the center of gravity is calculated in the range from 0.0 to
1.0withintheapertureangle.Theapertureangleisdenedbytheanglesontheleft
and right. A value of 0.5 corresponds to half the aperture angle (see Fig. 6). I.e., if the
