Chapter 3
A contamination error is also signalled on a digital or external output if this output is con-
figured for the status “Device Ready” (see
section 3.10.3 “Digital switching outputs” on
page 45 ).
Important If you use the “Contour monitoring with blanking” strategy (see section “Evaluation strate-
gy” on page 42 ) in the field evaluation application, the contamination measurement should
be configured as inactive. If the contamination measurement is active, erroneous detec-
tions of contour infringements may occur.
To ensure the reliable operation with deactivated contamination measurement it is
recommended to evaluate an external reference contour additional to the measurement
data output or detection field. If the LMS1xx is no more detecting the external reference
contour, it has to be assumed that there is a significant level of pollution.
3.7 Applications
In principle the LMS1xx can be used for two purposes:

for the measurement of objects (see section 3.8 “Measurement of objects” on
page 34 )

for the detection of objects with evaluation fields (see section 3.9 “Field application” on
page 40 )
Therefore, the possible applications are very wide-ranging. In particular the following can be
stated:

container loading/handling

traffic/transport

robots

object protection (low false alarm rate)
