2.2
Applications of the device
The VML Prime measurement system is used to determine object dimensions on flat belt
conveying systems with the help of light grids. Light grids are non-contact optical
measurement systems which detect the object contour using the principle of shadowing.
The use of light grids means it is even possible to recognize reflective, transparent, or very
dark objects, such as PET containers wrapped in film.
On the basis of the number of interrupted light beams, the evaluation unit simulates an
object model and derives the individual object dimensions from this. All information is
output to downstream systems via a central data interface for further processing.
VML Prime is available in different system variants.
• VML Prime 3D is made up of two light grid pairs which span the conveyor belt vertically
and horizontally. With this system variant, it is possible to determine the length, width,
and height of objects as well as the rotation of the object and the box volume.
• VML Prime 2D V is made up of a vertical light grid pair. With this system variant, it is
possible to determine the object height. If the objects are aligned on the belt, it is also
possible to determine the object length.
• VML Prime 2D H is made up of a horizontal light grid pair. With this system variant, it is
possible to determine the width and length of objects as well as the rotation of the
object. If the objects are aligned on the belt, it is also possible to determine the object
length.
Legal-for-trade mode
If VML Prime is used for billing purposes on the basis of the dimensions determined, the
measurement system must be operated with the VML520 MID or VML520 MID-s
calibratable system variant (in legal-for-trade mode, abbrev.: LFT mode). You can find more
information in the supplement to operating instructions (8021098).

Intended use
The VML measurement system may only be used as described in section 2.2 Applications
of the device. It may only be used by qualified personnel in the environment in which it was
mounted and initially commissioned by qualified safety personnel in accordance with
these operating instructions.
The equipment may be operated in an industrial environment. The system can be used for
the dimensioning of objects of any kind, before they are forwarded to downstream
systems.
For example, by way of the classification of objects into automated high bays, smooth
operation of the entire system, and of the conveying and sorter systems and storage and
retrieval systems in particular, can be ensured. Downtimes are reduced.
The VML Prime measurement system must not be used outdoors or in an
explosion-protected environment.
If used in any other way or if alterations are made to the system or the devices are opened
– including in the context of mounting and installation – this will void any warranty claims
directed to SICK AG.

VML Prime
To facilitate mounting of the system components on the customer’s conveying system,
aluminum profiles can be provided for constructing the frame.
In all system variants, the light grids are mounted between two conveyor belts. In the VML
Prime 3D system variant, the light grids are mounted at right angles for volume detection.
1 – The light grids
An MLG-2 light grid pair determines the object contour using the principle of shadowing. It
consists of a sender unit with emitting diodes and a receiver unit with receiving diodes.
The resulting field of measurement is determined by the beam separation and the number
of beams.
Receiver
Sender
Fig. 3:
MLG-2 sender and receiver unit
In the VML Prime 3D and VML Prime 2D V system variants, the vertical light grid pair also
provides information about when exactly an object enters the detection range (trigger). The
controller requires this information, together with the signals from the measuring wheel
encoder, to identify the exact position of the object on the conveyor belt. In the VML Prime
2D H system variant, a separate photoelectric retro-reflective sensor is used as a trigger
(see below).

VML Prime
1a – Protective pipe and cleaning unit (recommended)
We recommend fitting the VML Prime 3D and VML Prime 2D H system variants with a
cleaning set for the sender unit of the light grid mounted underneath the conveyor belt.
This prevents an increased risk of contamination of the emitting diodes due to the
horizontal mounting position of the sender below the belt.
Variant 1
The sender module (1) is mounted in a closed protective pipe made of plastic (2). The light
beams are directed vertically upward through the Plexiglas to the receiver diodes.
Fig. 6:
Variant 2
As in variant 1, the sender module (1) is pre-mounted in a closed protective pipe (2). In
addition, there is a vent duct with vent slot (3) mounted parallel to the plastic pipes, as
well as a fan with hose (4).

The light beams are directed vertically upward through the Plexiglas to the receiver diodes
(1). The air is blown into the vent duct and exits via the vent slot transversely over the
surface of the protective pipe (2), thereby blowing off any dirt particles on the surface of
the protective pipe.

Principle of operation of the cleaning unit
2 – Measuring wheel encoder
A measuring wheel encoder below the conveyor belt provides the exact position of the
object on the conveyor belt once it has passed through the photoelectric sensor.
Fig. 9:
Measuring wheel encoder
As part of this process, the measuring wheel encoder sends two incremental signals to the
controller – there is a 90-degree phase shift between the signals. Based on these signals,
it is possible to determine the speed and path of the object directly on the conveyor belt.
Measurement is performed directly on the running surface of the conveyor belt using a
precise measuring wheel, which is mounted on a spring-loaded arm.
The following operating instructions describe the DFV60 measuring wheel encoder.
Another incremental encoder, which has a minimum resolution of 1 mm, can be used.

VML Prime
2nd photoelectric retro-reflective sensor (VML Prime 2D H only)
The VML Prime 2D H system variant also uses a separate photoelectric retro-reflective
sensor as a trigger. The emitted light is reflected back by a reflector. The sender and
receiver are located in a single housing, where they are arranged parallel to one another.
Fig. 10: Photoelectric retro-reflective sensor
The photoelectric sensor provides information about when exactly an object enters the
measurement system via the CAN bus. The MSC800 requires this information, together
with the signals from the measuring wheel encoder, to identify the exact position of the
object on the conveyor belt.
Alternatively, the system can be triggered via the PLC of the conveying system.
The following operating instructions describe the WL-27 photoelectric retro-reflective
sensor. Another photoelectric retro-reflective sensor (e.g., WL18-3) can also be used.
4 – Controller cabinet with MSC800-1100
The controller cabinet contains the MSC800 controller (1) and the power supply unit for
the central voltage supply (2).
The MSC800 processes all signals from the system components and delivers the
measurement results to the higher-level system control. The data is delivered via a
customer-specific interface.
All the components are pre-mounted and pre-wired inside the controller cabinet.

Operating instructions | SICK
With the VML520 MID or VML520 MID-s calibratable system, the MSC800 is connected to
a second controller. Data is stored in the alibi memory and all additional sensors are
connected via this controller (see also chapter 3.2.4 Calibratable operation).

VML Prime
Supplementary system components
In principle, AutoIdent systems or scales can also be added to the VML Prime
measurement system.
 AutoIdent systems: Laser scanners and camera-based systems allow the automatic
identification of the object using its bar code, thereby accelerating process automation.
The LTR data for focusing the camera systems is provided by VML Prime.
 Scales: The in-motion scales determine the weight of the passing object. The weight,
together with the bar code and the calculated volume, can be transmitted for the
purpose of controlling the goods and material flow.
3.2.2
VML Prime operating principle
The VML Prime measurement system dimensions individual objects on flat conveying
systems. The objects must not be placed side by side and there must be a minimum
distance of 200 mm (measured from the rear edge of the object to the front edge of the
subsequent object) between them as they are being transported.
Fig. 12: Correct minimum distance between objects
Objects that are touching or lying side-by-side cannot be measured using the VML Prime.
Fig. 13: Non-permissible object positions (touching and side-by-side)
Recording the measured values
The light grids span one horizontal and/or one vertical monitoring field. Providing no object
is located within this field, the light beams from the sender lines will hit the diodes of the
receiver lines.

Operating instructions
VML Prime
If the monitoring field is interrupted by an object, the shadowing and the resulting number
of light beams prevented from reaching the receiver lines can be used to detect the profile
of the object.
The change in the number of beams at the receiver lines resulting from this shadowing is
transmitted to the MSC800 via the light grid interfaces in the form of a digital signal.
Calculating volume with VML Prime 3D
The motion of the object generates two-dimensional sections in the VML Prime 3D system
variant.
Fig. 14: VML Prime 3D operating principle
The individual 2D sections of the object are merged together in the MSC800. When the
transport speed and the position of the object on the belt are also taken into account, a
three-dimensional image can be rendered. The smallest enveloping cuboid and volume of
this image can then be determined from this.
To calculate the length, the system needs to know the position of the object on the
conveyor belt after it has passed in front of the trigger. This is provided by the measuring
wheel encoder in the form of incremental signals.
Calculating height and length* with VML Prime 2D V
In the VML Prime 2D V system variant, the vertical light grid pair provides one-dimensional
rows of dots of the respective object side.

VML Prime
The individual 2D rows of dots of the object are merged together in the MSC800. To
calculate the side contour, the most extreme/highest point of the incoming data is always
evaluated. When the transport speed and the position of the object on the belt are also
taken into account, a two-dimensional image can be rendered, from which the object
height is detected.
* VML Prime 2D V can also output the trigger length, which corresponds to the object
length with aligned objects.
Calculating the width, length, and angle of rotation with VML Prime 2D H
In the VML Prime 2D H system variant, the horizontal light grid pair provides onedimensional rows of dots of the object or profile width.
Fig. 16: VML Prime 2D H operating principle
The individual 2D rows of dots of the object are merged together in the MSC800. To
calculate the object contour, only the outer points in the row of dots are evaluated. When
the transport speed and the position of the object on the belt are also taken into account,
a two-dimensional image can be rendered. The object length, the object width, and the
rotation of the object on the conveyor belt can then be determined from this.

3.2.3
Data output
All information converges in the MSC800 central control unit. The MSC800 processes the
trigger signal and forwards the object’s position so that the length can be calculated.
The data of all measurement results is output to the higher-level system control by the
host data interface. Alternatively, the digital switching outputs of the MSC800 are
available for further processing of the deformation result.
In addition to the measured values, the LTR data for camera focusing can also be
transmitted if desired.
The calculated measured values are typically transmitted to downstream systems 350 ms
after the measuring range (1) at the earliest, measured from the back edge of the object
(3). The time of the data output can be configured at will (see chapter 6.4.6 Configuring
the data output).
The object release time (2) refers to the point in time by which the calculation of the
measurement data must have finished. The object release time (also measured from the
back edge of the object) must be before the data output time.

Conveying system requirements
The following requirements apply to the conveying system and the objects that are being
transported:
• The two adjacent conveyor belts must run at the same speed, and must be horizontally
aligned.
Fig. 18: Conveying system requirements
• An ideal measurement result is achieved when the width of the belt gap is 10 mm.
• It must be ensured that the objects travel along the conveyor belt one by one.
• If the objects rotate, vibrate, roll, or slip on the conveyor belt and on uneven conveying
surfaces, the accuracy may be reduced, and this may influence the measuring behavior
of the VML Prime measurement system.
The measuring range of the horizontal light grid must cover the full width of the conveyor.
Here, the points of reference are
• the edges of the conveyor (in the case of conveying systems without guiding plates); or
• the inner edge of the guiding plates.

Mounting requirements
Frame
The VML Prime measurement system requires both a stable, secure frame to prevent
rotation and a sufficient load bearing capacity to support the light grids and the controller
cabinet, where applicable.
• The frame must be assembled in such a way that it is free of vibrations and oscillations.
• The frame must be rectangular, and must be positioned at right angles to the conveying
direction.
• The frame must be firmly anchored in the ground.
To achieve a high level of measurement accuracy, use the optional item aluminum
profiles or a steel frame construction in the defined dimensions.

Mounting the light grids
The light grids are mounted on the frame in such a way that both light grid pairs form a
rectangular detection field in the middle of the point of transition between the two
conveyor belts.
The light beams of the vertical and horizontal light grids must be aligned. The beams are
offset by 2 mm, meaning that the senders and receivers must be aligned with each other
exactly.
Fig. 21: Misaligned light beams
Optimizing the measurement results
To achieve an optimum measurement result, observe the following:
• The light grids must be far enough away from bends, induction lines, start/stop areas,
areas with upward and downward slopes, and breaks in the conveying system.
• The conveyor speed must be constant from the measurement start point up until
leaving the reading field. Both conveyor belts must run at the same speed.
• The measuring wheel encoder should be mounted on the belt element in such a way
that a good connection is formed between the encoder and the belt. At this point, the
belt should run with as little vibration as possible

Assembling the item aluminum frame
4.2.1
Frame components
The frame that holds the device components is constructed in the form of a gate around
the conveying system. The gate must be mounted at the gap between two conveyor belts
so the light beams from the light grid fall on the center of the gap.
The gate frame is usually made up of individual aluminum profiles. The height and width of
the profiles are customer-specific. More detail can be found in the delivery specification.
The frame consists of the following components:
Fig. 25: item mounting frame: components

Designation
1
Carrier profiles
2
Transverse profiles for connecting the two carrier profiles
3
Brackets for stabilizing the frame
4
Longitudinal and transverse profiles for constructing the foot and for
mounting the devices
5
Angled feet for leveling and anchoring the frame to the floor
Tab. 8: item mounting frame: components
The aluminum profiles are mounted using the universal connector for extruded aluminum
profiles that is included with delivery. Universal connectors for extruded aluminum profiles
are rectangular friction-fitted aluminum profile connectors that can be adjusted.

Mounting the light grids
4.3.1
Overview
Mount the vertical and horizontal light grid components on the frame in the order
described:
1. Horizontal receiver at the top
2. Horizontal sender (in the protective pipe if necessary)
3. Vertical receiver on the right (in conveying direction)
4. Vertical sender on the left (in conveying direction)
Fig. 32: Mounting the components (overview)
Notes
• The end with the cable connection on the associated sender and receiver units must
always point in the same direction. Due to the beam offset of 2 mm, the cable
connections for the horizontal light grid (in conveying direction) must point to the right
and the cable connections for the vertical light grid must point downward.
If they are mounted inversely, the monitored areas will not be in a single plane.
• The light grid is mounted (in conveying direction) behind the frame.
• Sender and receiver must not be installed at 180° rotated relative to each other. The
sender and receiver must be mounted in the same orientation.
• Sender and receiver can each be recognized via an icon on the type label.
Icon
Designation
Sender unit
Receiver unit
Alignment
All light grid beams must lie exactly on a single plane. The light beams sent must fall
exactly on and at a right angle to the relevant receiver unit diode. To achieve this, the
components must be aligned on the frame.
The frame must ensure that the vertical light grids are orthogonal to the conveying system
and the horizontal ones are parallel to it.

Making sure the light beams fall on the center of the gap
Firstly, make sure that the light grid beams fall on the center of the gap.
1. Move the frame with the mounted light grids in the x-axis until the component diodes
fall on the center of the gap. Use the upper horizontal grid as a reference.
Fig. 51: Making sure the light beams fall on the center of the gap
2. Check they are centered using a plumbline. To do this, first place the plumbline on the
first diode of the horizontal receiver.
Tip
In order to be able to identify the diodes better behind the blackened glass of the
receiver, it is best to illuminate them with a flashlight.

4.3.4.2
Adjusting the horizontal light grids
The sender and receiver of the horizontal unit must be in the same plane and aligned
vertically to the conveying system.
Adjusting the sender
If the (lower) horizontal sender is attached without the protective pipe using the QuickFix
brackets, this generally ensures that the sender and receiver are positioned at a right
angle to the conveying system due to the orthogonal alignment of the mounting frame.
By screwing the two fixing screws into the upper bracket, the sender located in the
protective pipe is already aligned correctly.
Adjusting the position of the first horizontal receiver diode
Align the components of the horizontal light grid so the diodes cover the entire monitored
area. The first diode (the right-hand one viewed in the conveying direction) must be at least
2 mm away from the edge of the conveyor or from the lateral boundary when the
measuring range is the same as the belt width. If the light grid covers more than the
monitored area, it should project to the right and left above the conveyor.
Fig. 54: Adjusting the position of the first horizontal receiver diode
1. Check the distance of the first diode using a plumbline. As described previously, place
the string of the plumbline on the horizontal receiver diode.
2. Move the receiver until the plumbline meets the right-hand edge of the conveyor. That is
either the inner edge of the lateral boundary or the outermost point where an object
could be as it passes through.
3. Then move the receiver in the profile slot to the edge or 2 mm away from the edge
respectively.
4. Then tighten up the Allen screw on the QuickFix bracket.
Adjusting the position of the first horizontal sender diode
Adjust the position of the first sender diode.
 Without protective pipe: Move the QuickFix brackets on the horizontal sender in the
profile slot.
 With protective pipe: If the measuring range is the same as the belt width, move the
two protective pipe brackets in the profile slot until the first diode is 2 mm away from
the right-hand edge of the conveyor. Otherwise, align the first diode with the lateral
boundary.

Checking the correct position of the first diode
The alignment must ensure that the light grid beams fall exactly in a single plane and that
each emitting diode meets the opposite receiver diode vertically.
Check the correct position of the first two diodes using a plumbline.
 Without protective pipe: Place the string of the plumbline on the first receiver diode.
The plumb must fall exactly on the first sender diode.
 With protective pipe: When the light grid is mounted in the protective pipe, the plumb
needs to fall from the (in conveying direction) left mechanical end of the upper light grid
on the upper bracket of the protective pipe (top of MLG).

1. First move the vertical receiver in the z-direction until you have achieved the required
distance between the first diode and the belt.
Tip
In order to determine the required distance more precisely, place a sheet of paper on
the gap. This provides a clearly defined zero point for measuring the height.
2. Take the sender to the same height.
3. Place a board or a profile on the two components.

Fig. 119: Checking voltage supply to the light grids
Checking signal strength
Yellow (3 Hz)
After the system is switched on for the first time, the alignment mode for coarse
alignment is active at the receiver unit. The yellow LED on the receiver unit flashes rapidly
if the signal it is receiving is too weak. The LED goes out as soon as the signal strength is
sufficient.
Note
The LED behavior does not provide information about optimum alignment of the
components. It only indicates whether the signal arriving at the receiver is strong enough.
After the first teach-in process, the alignment mode is deactivated.
Checking whether objects are detected
 Move an object into the monitoring field. The yellow LED must light up on the receiver of
each of the light grid pairs. The yellow LED lights up if at least one beam of light is
interrupted.

Teaching in light grids
The light grids must be taught in during initial commissioning.
The teach-in process ensures optimum sensitivity of the light grids. For this, the switching
thresholds for all beams are adjusted for the sensing range and the ambient conditions.
Prerequisites
Before the teaching in the light grids, the following prerequisites must be fulfilled.
 Clean the front screen of the MLG-2 modules.
 Stop the conveyor belt to prevent vibrations during the teach-in process.
 Remove all objects from the detection field. During teach-in, there must be no objects
in the light path.
Performing the teach-in process
Both light grid pairs are taught in separately.
1. In the Teach MLGs area, click the Teach Y-MLG button. The horizontal light grid pair is
taught in.
At the MLG-2 receiver, all LEDs will briefly illuminate one after the other. The yellow LED
flashes slowly during the teach-in process.
If the teach-in process has been successful, the yellow LED on the receiver will go out. A
successful teach-in process will be indicated by a green light symbol on the page of the
wizard.
2. Perform the teach-in process in the same way for the vertical light grid pair.
Teach-in process unsuccessful
If the teach-in process for a light grid pair has been unsuccessful, the red LED on the
relevant receiver will flash rapidly. A red light symbol will be displayed on the page of the
wizard.
 In this case, check that the light grid pairs are correctly aligned, that the front screens
are clean, and that there are no objects located in the light path.
 Then carry out the teach-in process again.
 Check whether the MLG-2 sender is connected.

Permanently blanking beams (for systems with guiding plates or protective barriers)
If beams are shadowed during the teach-in process, this will be taken into account
accordingly for all measurements in future.
Therefore, it is essential that no objects are accidentally located in the light path.
The targeted exclusion of certain beams is only intended for conveying systems with
guiding plates or protective barriers, if the latter permanently shadow individual diodes.
Through the teach-in process, VML Prime can be adjusted to the permanently shadowed
diodes so that this does not have a disruptive effect on the calculation of measurement
values.
In doing so, it does not matter if there are diodes below the guiding plates or not. No
measuring points below the guiding plates are required for measuring objects.
Fig. 128: Permanently blanking beams
The one prerequisite is that the object height to be measured is higher than the guiding
plates.
6.4.3
Calibrating light grids in relation to the coordinate system of the conveyor
The position of the light grids in relation to the origin of the conveyor is determined using a
reference box.
We recommend using the SICK reference box available as an accessory with the defined
dimensions 402 mm x 302 mm x 202 mm. This reference box can be ordered from SICK
using part number SICK PN 4040035.
The reference box is placed in different positions on the conveyor belt and measured. The
wizard determines all key system parameters, such as resolution, detection height, and
detection width, from the measured values.
These values only need to be checked for plausibility and then saved.
Getting started
 Click Next to end the successful teach-in process for the light grids. You will end up at
the position wizard.

Configuring the data output
In the Data Output workspace, you can configure the data interface and the format for

The MSC800 is essentially set up as a server within the network. This means that the
measurement results are initially buffered and retrieved by the client computer. The
TCP/IP network protocol is used.
Configure the data interface in the Ethernet area. A static address is used for the MSC800
by default.
1. In the IP address field, specify the IP address at which the MSC800 can be reached in
the customer’s network. The field contains the preassigned default IP address
192.168.0.1. If necessary, change the IP address accordingly.

3. Define the reference point of the data output and the output time using the Output
related to and Position (1) fields.
• The data output time is usually related to the trailing edge of the object. This is also
the default setting. In this case, the information in the Position field calculates the
output time as a distance value from the trailing edge to the measuring range.
The output time therefore depends on the object length.
• If the reference point for the data output is switched to the leading edge, you must
take the object length into account when specifying the distance value. The distance
value must not be smaller than the maximum object length plus the calculation time
for the path of 300 ms.
Select this setting if you wish to always have the same output time, regardless of the
object length.
4. The Output length in conveyor direction checkbox is ticked by default. This means
that the length of the object is always determined in the conveying direction, even if
this is not the longest side of the object.
If you untick the checkbox, the VML Prime determines the longest side, regardless of
the orientation of the object on the conveyor belt.

The measurement results from the measuring runs are listed line-by-line in the Volume
Result table.
This list can be used to verify the measurement accuracy of the system.
 Make sure that the calculated measured values are within the tolerance range.
 Make sure that the measured values are also correct for all orientations of the object.
Displaying the status
If the measurements are free of errors, a value of 0 appears in the VMD Status 1 column.
If there is an incorrect measurement, further information on the error can be provided by
the status value.
 For this, show the VMD Status 2 and VMD Status 3 columns using the arrow button in
the table header.
 The table in the appendix shows how you can decode the errors using the numerical
code (see chapter 9.4 Error codes (VMD status)).
If no dimensions are calculated
If no dimensions are calculated, proceed as follows:
 Check that the system has been cabled correctly.
 Ensure that the signal ground of the measuring wheel encoder and the trigger is
switched on.
 Check that the encoder parameters have been determined correctly.

Optimizing the measurement results
If necessary, the measurement results can be optimized even further.
6.6.1
Optimizing the height measurement
In the example, we can see that the height measurement does not fall within the tolerance
limit. Here, the reason for this is that the vertical light grid is mounted too low. As the first
diode is below the conveyor belt, and the height is determined from the furthest shadowed
diode from the bottom diode, the measurement result displayed is too high.
The height measurement can be adjusted by adjusting the z-coordinate in the coordinate
system. In the example, the z-axis is moved upward by 18 mm (reference value – actual
value) so that it is at the same height as the conveyor belt.
Fig. 129: Optimizing the height measurement
 Go to the System Configuration workspace in the SOPAS configuration and analysis
interface and adjust the Z-MLG position.
As a rule, the following applies:
 If the measurement result is smaller than the actual height value, reduce the zcoordinate (+X mm).
 If the measurement result is larger, increase the z-coordinate (-X mm).

Optimizing the length measurement
If a systematic length error occurs, the length correction factor of the incremental encoder
may need to be adjusted.
Note
Do not change the factor manually in the System Configuration workspace.
Call up the VML encoder wizard and correct the factor by carrying out new measurements
of the reference object (see chapter 6.4.4 Calibrating the incremental encoder).
6.6.3
Optimizing the width measurement
The width values determined should not require measurement calibration if the light grids
have been correctly mounted and aligned.
If deviations from the required width of the reference box should arise, however, this could
be a result of misalignment of the two horizontal MLG-2 components in the y-direction.
Fig. 130: Optimizing the width measurement
This would mean that although the beam still hits the receiver diodes due to beam
expansion in this case, it does not do so at the perpendicular angle required. Due to the
inclination of the light beams, an object might shadow more diodes than if the beam were
pointing in a vertical direction, resulting in a deviation in the width measurement.
 Check the mechanical structure of measurement assembly and correctly align the
horizontal components with the y-axis.

The following behavior of the LED receive indicator suggests a fault/error:
LED
Meaning
Permanently off
Reflector is not aligned with the light beam of the photoelectric
sensor.
Flashing
 Readjust the photoelectric sensor, clean it, or check the
application conditions.
Reflector is only being detected in the fringe range.
 Readjust the photoelectric sensor, clean it, or check the
application conditions.
Lit or flashing even
when there is an
object in the path of

Detailed fault analysis in SOPAS
The SOPAS configuration and analysis interface helps to analyze faults.
 Start SOPAS configuration software and establish a connection to the system.
Measurement error
Measurement errors are documented directly in the measurement value table in the Start
workspace using error codes.
If the measurements are free of errors, a value of 0 appears in the VMD Status 1 column.
If there is an incorrect measurement, further information on the error can be provided by
the status value.
 For this, show the VMD Status 2 and VMD Status 3 columns using the arrow button in
the table header.
 The table in the appendix shows how you can decode the errors using the numerical
code (see chapter 9.4 Error codes (VMD status)).

System messages and error codes
The Diagnostic workspace lists both system and error messages.
Fault output is staggered, allowing for an increasingly detailed level of analysis.
Communication errors can occur when transmitting telegrams to the MSC800 via the
Ethernet interface, for example.
The system differentiates between four error types: information, warning, error, and
severe error.
Note
Please contact SICK support for a more detailed analysis of the fault situation.
Cause of severe measurement errors
Severe measurement errors can be caused by various factors, including:
Cause
Remedy
Static object in measuring
range
 Remove the object from the measuring range.
Although the MLG-2 is no
longer taking measurements,
it is not indicating a fault
 Check the connecting cables and replace defective
cables.
 Check the MLG-2 and, if necessary, replace the
device.
 Check whether the trigger is permanently engaged.
There is no/insufficient
contact between the
measuring wheel and the
conveyor belt
 Check the measuring wheel for signs of wear.
 Replace the measuring wheel encoder if necessary.

VML Prime data sheet
Component
Explanation
Min. object size
(L x W x H)
Up to 50 mm x 50 mm x 5 mm
The minimum detectable object size depends on the
beam separation and the conditions of the conveyor.
The minimum object length depends on the diameter
of the roll at the belt gap. It is calculated using the
following formula:
L (min.) = 2.5 * Ø (roll)
Max. object size
(L x W x H)
2,600 mm x 1,000 mm x 1,000 mm
Conveying system
• Flat conveying surface
Higher object sizes on request.
• Both belts synchronized at the same
speed
• On one level, not misaligned
• Singulated objects (see minimum distance)
Dimensioning accuracy
(L x W x H)
Up to ± 5 mm x 5 mm x 2 mm up to 1.0 m/s
Up to ± 5 mm x 5 mm x 5 mm up to 2.0 m/s
The values depend on the beam separation and the
belt speed.
Higher speeds on request.
Minimum distance between
objects
200 mm
Minimum distance between the
vertical light grid and the first
data output point
Data output typically occurs 300 ms (milliseconds)
after the measuring range at the earliest (measured
from the back edge of the object* and depending on
the maximum object size and conveyor speed).
* Assumed max. object dimensions
650 mm x 650 mm x 450 mm (L x W x H)
