3 Device description
3.1 General information
The contour measuring system CMS 700i is a complete system consisting of:
Light curtains,
An evaluation unit and
An encoder, depending on the version.
The evaluation unit is responsible for data acquisition, processing and preparation. The system
provides the process data via defined interfaces such as Profinet or Ethernet TCP/IP.
The integration of peripheral devices such as scales, barcode readers and cameras is possible. The
evaluation unit loops through the peripheral data unprocessed as part of its TCP/IP protocol.

4 Functions
4.1 Operating principle
The contour measuring system CMS 700i detects of an object of any shape:
Length, width, height of the smallest enveloping cuboid
Rotation angle to transport direction
Smallest vertical distance between the object and the conveyor belt.
All objects are measured as they pass through.
System setup with 3 light curtains
Measurement start: Interruption of the first beam of the length light curtain or trigger by an optional
trigger.
Measurement stop: No beams of the width and height light curtain are interrupted.
System setup with 2 light curtains and 1 rotary encoder
Measurement start: Interruption of one beam of the height or width light curtain or trigger by an
optional trigger.
Measurement stop: No beams of width and height light curtain are interrupted.
After the measurement, the control unit (LSC-Box) automatically forwards the calculated object data to
a host via a fieldbus interface. Data from other peripheral devices such as scales or barcode readers
can also be transferred in the interface protocol. After data output, the next object can be acquired.
NOTICE
Important for valid measurement!
As long as the measurement is running, the beams of the light curtains must not be
additionally interrupted by manual interventions or other actions! This falsifies the measured
values.
Observe minimum object distance and maximum transport speed! See chapter 4.5.

4.2 Object rotation angle, object length and width
Object rotation angle:
The object rotation angle determined by the CMS 700i is the angle between the longitudinal edge of
the measuring object and the vector of the conveying direction.
The angle can take values between -45° and +45°. When the rotation angle of 45° is exceeded the
assignment of length and width changes and the smaller value with alternate sign is sent out, see
Figure 4.
Object length:
The object length or length is defined as the side of the object in top view that is at an angle of less
than 45 degrees to the conveying direction (= longitudinal direction).
Object width:
In the top view, the side adjacent to the object length is the object width.

4.3 Object overhangs, object bulges
This chapter describes the function of overhang suppression and the detection of bulges. For the
settings of these functions in WebConfig, see Chapter 8.2.2.
The evaluation of measurement objects for projections and bulges is always carried out in 2 steps.
4.3.1 Operating principle
In stage 1, the system determines overhangs in length, width and height from the raw object data and
suppresses them according to the threshold value entered. The suppression serves to ensure that
overhangs on the object that do not interfere with further handling do not influence the object
measurement.
In stage 2, the system determines the cuboid corner points of the object from the overhang-reduced
object data and calculates the bulges between the corner points. The determination of the bulges is
called deformation detection.
Deformation detection can only be selected in conjunction with object overhang detection.
Example
Figure 5 shows an object with overhang and bulge. The overhang has the width ∆A. The bulge has a
maximum length of Xnet-Xmin.
Figure 5: Object with overhang and bulge shown in blue.
The following cases may occur.

The overhangs and bulges can occur in longitudinal, width and height direction.
The following figure of an object (grey box) on a conveyor serves for orientation of the direction
information. The red bars represent the light curtains. The grey arrows indicate the conveying
direction.
Figure 6: Views to display the direction information.
4.3.2 Overhang suppression Length
If the width of the overhang ∆A is smaller than the threshold value entered, it is suppressed and not
taken into account in the length measurement.
NOTICE
The overhang suppression and deformation detection is also carried out for the versions with
rotary encoder for longitudinal measurement.
Figure 7: Schematic representation of an object overhang in longitudinal direction

Leuze electronic
CMS 700i –Contour Measurement System
Page 16
4.3.3 Overhang suppression Width
If the width of the overhang ∆A is smaller than the entered threshold value, it is suppressed and not
taken into account in the width measurement.
Figure 8: Sketch of an overhang of an object in width direction
4.3.4 Overhang suppression Height
If the width of the overhang ∆A is smaller than the entered threshold value, it is suppressed and not
taken into account in the height measurement.
Figure 9: Sketch of an overhang of an object in height direction
4.3.5 Deformation detection
The system detects bulges as deformations that protrude from the projected view of the object, see
Figure 10.

Leuze electronic
CMS 700i –Contour Measurement System
Page 17
Figure 10: Top view of an object with lateral bulge
Limitations of deformation detection
Deformations that protrude into the object and are shaded by edges cannot be detected by the system
as shown in the following figure. In this case Xnet < Xmin.
Figure 11: Object with inward bulge
If, as shown in Figure 12, the smallest enclosing perimeter (blue) is much smaller than the object
perimeter (red), a deformation cannot be distinguished from the rest of the object structure.
In this case, after the measurement, the system outputs the status NOK and the length, width and
height of the smallest enveloping box (including all projections of the object).
Figure 12: Object sample which smallest enclosing perimeter is much smaller than the object perimeter
4.4 Minimum distance between two objects
Formula for calculating the minimum distance Dmin between two objects:
Dmin = 12 x [Fix resolution of CML 730: 5mm] + [Cycle time: 50ms] x [Conveying speed v in m/s]
Sample calculation with conveying speed v = 0.8 m/s
Dmin = 12 x 5mm + 50ms x∙0.8 m/s = 100mm
4.5 Maximum conveying speed
NOTICE
Be sure to observe the maximum conveying speed!
If the maximum conveying speed is exceeded, the system may not provide reliable
measurement results.

Leuze electronic
CMS 700i –Contour Measurement System
Page 18
The maximum conveying speed depends on the added measuring length of width and height light
curtain. To determine the maximum conveying speed:
1) Read the measuring lengths on the type plates of the height and width light curtains.
2) Add both values and
3) Read off the conveyor speed in the following diagram for the appropriate sum.

5 Mounting and installation
5.1 General information
The exact alignment of the light curtain pairs to each other directly influences the quality of the
measurement results. The system should be mounted on a largely vibration-free frame. Strong
vibrations can falsify the measurement result. The figures are valid across all interfaces for all
connection types. The respective interface chapters provide specific connection diagrams.
5.2 System with 3 light curtains
NOTICE
The following installation instructions must be observed!
The light curtains for height and width must be on the same level.
The first beam of the length light curtain must be in front of the plane of height and width.
The light curtains for length, width and height must be at right angles to each other.
The length light curtain must be oriented parallel to the conveying direction.
