Notes
■
You can only select one of the following evaluation modes: Standard, Blocked
Beams Hold (BBH) or Lost Beams Hold (LBH)
■
The Lost Beams Hold (LBH) evaluation mode affects all beam functions.
Description of operation
In the Lost Beams Hold (LBH) evaluation mode, a blocked beam is displayed as a blocked
beam until a new beam is blocked. This allows the position to be determined for objects
that are smaller than the minimum detectable object.
This evaluation mode assumes that the object being detected is always positioned
within the detection area. This means that the object must be located either above or
below the last beam blocked when a previously blocked beam is no longer blocked and
a different beam is not yet blocked. Once the object blocks a different beam, this new
position is detected and the saved last beam blocked is deleted. If the object moves
outside the detection area, the last beam blocked remains blocked.
Example
The Lost Beams Hold (LBH) output mode is used to detect the position of thin objects that
are no longer detected with a parallel beam.
Configuring the Lost Beams Hold (LBH) function via SOPAS ET

►
In SOPAS ET, click on the Beam evaluation expandable menu in the right-hand
window.
►
In the Evaluation mode area, select the Lost Beams Hold (LBH) evaluation mode.
✓
The message "Lost Beams Hold selected" appears in the Configuration area. This
function affects all process data".
✓
At the bottom of the E/A tab in the left-hand window, the beam evaluation mode
OFF, Blocked Beams Hold or Lost Beams Hold is displayed.

Simulation
If you configure an MLG-2 offline – i.e., without a connection to the device – you can
simulate the operation of the MLG-2 using simulation objects. The objects required
for the simulation can be set via the expandable Simulation menu. This includes the
number of objects, their shape, size, and speed.
►
Click on the plus sign to add a simulation object.
