2.
Laser Safety
The scanCONTROL 27x0 sensors operate with a semiconductor laser having a wavelength of 658 nm (visible/red). The laser operation is indicated visually by the LED on the sensor.
When operating the scanCONTROL 27x0 sensors, the relevant regulations according to EN 60825-1
(IEC 60825, Part 1 of 11/2001) and the applicable accident prevention regulations must be followed.
The housing of the scanCONTROL 27x0 optical sensors must only be opened by authorized persons, see
Chap. 8. For repair and service, the sensors should always be returned to the manufacturer.
2.1
Laser Class 2M
scanCONTROL 27x0 sensors with a maximum laser power up to 10 mW, see Chap. 3.2, are classified in
Laser Class 2M (IIM).
Accordingly, the following applies:
With laser equipment of the Class 2M, the eye is not put in danger during random, short-term exposure to the
laser radiation, i.e. exposure duration up to 0.25 s.
Hazard to the eye via
laser radiation!
Consciously close
the eyes or turn away
if the laser radiation
impinges on the eye.
A direct glimpse into the beam can be dangerous if the eye-closure reflex is deliberately suppressed, e.g.
during adjustment. Direct viewing into the beam with optical aids, e.g. a magnifying glass, is dangerous.
Laser equipment of the Class 2M can be employed without further protective measures, when deliberate
viewing into the laser beam or into a beam reflected by mirrors is not longer than 0.25 s.
Since generally the presence of the eye-closure reflex should not be assumed, one should close the eyes or
immediately turn away if the laser radiation impinges on the eye.
The following information labels are fitted to the sensor housing (front and rear side):

user for the region applicable in
each case before the equipment
is put into operation.

scanCONTROL 27x0
Laser Class 3B
scanCONTROL 27x0 sensors with a maximum laser power up to 20 mW, see Chap. 3.2, are classified in
Laser Class 3B (IIIB).
i
Sensors of laser class 3B (IIIB) need an external key switch to switch off the laser, see Chap. 5.2.5. Accordingly, the following applies: The available laser radiation is hazardous for the eyes and usually for
the skin also. Looking directly into the laser beam is hazardous for the eyes. Also reflections on shining
or mirroring surfaces can be hazardous to the eye. Hazards to the skin through the available laser radiaPage 11

tion are given by class 3B (IIIB) laser equipment if the values of the maximum permissible exposure are
exceeded.
If the sensor is on the laser output can be reduced to 10 mW with the software. Reducing the laser output to
1 mW is not possible. Reducing the laser output from 20 mW to 10 mW with a software affects not the laser
class!
The following information label should be fitted to the sensor housing (front and rear side):

Functioning Principle, Technical Data
3.1
Brief Description
3.1.1
Measurement Principle
The scanCONTROL 27x0 sensor operates according to the principle of optical triangulation (light intersection
method):
-- A laser line is projected onto the target surface via a linear optical system.
-- The diffusely reflected light from the laser line is replicated on a sensor array by a high quality optical system and evaluated in two dimensions.
The laser line triangulation corresponds in principle to the triangulation of a laser point. In addition, during the
measurement a row of lines are simultaneously illuminated by the laser line. Apart from the distance information (Z-axis), the exact position of each point on the laser line (X-axis) is also acquired and output by the
system.
3.1.2
System Setup
The scanCONTROL 27x0 measuring system is a compact sensor with an integrated controller. All necessary
integral parts are combined in one housing.
3.1.3
Special Performance Features
-- scanCONTROL features speed and compact design with simultaneously high measurement accuracy. A
special line-scanning optical system ensures uniform exposure of the measuring field.
-- The sensor array is arranged in the sensor head according to the Scheimpflug condition which facilitates
uniform image focusing over the whole depth of the measurement range (Z-axis).
-- scanCONTROL works even without a PC in conjunction with saved configurations. The sensor runs the
profile measurement internally and calculates default measured values such as angle or edge position.
The measured values can be processed directly in a PLC via the digital inputs /outputs in connection with
the scanCONTROL Output Unit. Furthermore, a determination of internal limit value with subsequent output of the evaluation results (good / bad) is possible via the switching outputs. This series with integrated
profile evaluation is named scanCONTROL 2710.

3.1.4
Advantages of the Used Sensor Array (Difference to Conventional Line Scanners)
-- A global shutter (high speed shutter) for the whole profile enables a high profile accuracy for fast applications.
-- The array enables the simultaneous exposure and reading of the previous image. Thus the exposure time
is longer at the same profile frequency. With it also dark objects can be measured with a high rate.
3.1.5
Further Features
-- The sensors are available in two versions: Connectors on the front or on the rear side.
-- External synchronization and triggering.
-- Serial interface (RS422) for communication with PLCs or PCs.
-- The automatic control of the exposure time enables consistent measurement results with changing surfaces. This function can be switched off on request.
-- Selectable Firewire (IEEE1394a) or Ethernet 100/1000 Mbit as fast standard connection to the PC.

Mounting
5.1
Attachment and Mounting of the Sensor
The sensor can be mounted in two different ways:
1. with 3 threaded holes M4 on the front side or
2. with 3 threaded holes M4 on the side surfaces.
All threaded holes are 5 mm deep blind holes.
Refer to the dimension drawings for the mounting dimensions.
Pay attention to careful handling during mounting and operation.
> Damage to or destruction of the sensor
Pay attention to the depth of the blind holes during selection of the fixing screws
>> Damage to the thread due to screws resting on it.
The tightening torque must not be selected too high.
The laser beam should strike the target surface at right angles. Otherwise, inaccurate measurements cannot
be ruled out.

All switching signals are built in the same way. The programming specifies the assignment as inputs or outputs. The switching circuits used have internal potential isolation.
No potential isolation between 24 V supply ground and internal circuitry, see Fig. 18 (left side). A ground
connection (GND1 and GND2) is assigned to each channel. The ground connections are connected with
each other and must be connected with the ground connector of a synchronization/trigger source or a serial
device.
scanCONTROL 27x0
The channels Ch1 and Ch2 can be used for the following functions:
-- Serial interface RS422 in duplex or simplex mode (Rx and Tx).
-- Synchronization: Using the synchronization signals, several sensors can be synchronized with each other
or individual profiles (scans) can be triggered.
Page 33

-- Optional additional functions (trigger, encoder).
-- External wiring must be performed according to the RS422 standard. Primarily use RS422 driver circuits or
converters. Alternatively use devices with RS422 connectors, e.g. sensors, encoders or SPC‘s.

Also connect both the GND1 pins (Pin 5) of the sensors to each other.
The cable connection must preferably be made using a shielded, twisted-wire cable whereby the cable shield is
connected to the connector cases. The sensor 1 as master then synchronizes sensor 2.

FireWire Connection (1394)
The FireWire connection is the standard connection to the PC for sensors without option and sensors with the
options 001, 002, 003, 004 and 005, see Fig. 15 plug-in connection ”1394/ethernet”. The high data rate allows
the simultaneous operation of several scanCONTROL 27x0 on one IEEE1394 (FireWire) PC plug-in card.
The scanCONTROL 27x0 sensor can also be supplied with operating voltage from the PC on the 1394
connection socket. If its capacity is not sufficient, an appropriate voltage must be connected to the 24 VDC
socket, see Chap. 3.2.
We recommend the FireWire connection cable SC2700-4,5 FireWire from the optional accessories, see Chap.
4.2.2, for use with the FireWire connection.
Further information and links can also be found on the World Wide Web, e.g. at www.firewire-infos.de.
MICRO-EPSILON makes no guarantee for the contents and property rights of the named source.
Use the recommended FireWire connection cable.
Install the driver ([CD]:\\Documentation\english\Installation\index.html). Now connect the connection
cable to the PC. This sequence avoids problems.
A power supply via free cores in the FireWire connection cable is possible if these wires are connected in the
PC (Pin 1 to +8 … 30 V DC, typically 12 V DC; Pin 2 to ground on the FireWire connector).

Ethernet Connection
The Ethernet connection is the standard connection to the PC for sensors with the following options: 500,
501, 502, 503, 504 and 505, see Fig. 15 plug-in connection “1394/Ethernet”. The sensor supports the transmission at 100 Mbit/s and 1 GBit/s.
We recommend the Ethernet connection cable SC2700-5/ET or another length included in the optional
accessory, see Chap. 4.2.2, for the Ethernet connection.
For the power supply a corresponding voltage, see Chap. 3.2, has to be connected to the socket 24 VDC.
Due to a high data rate, we recommend using a high-quality Ethernet PC plug-in card, for example IntelPro/1000 PT. The sensors are to be preferably connected directly to the network connection or by means of a
high-quality switch. As a hub would result in a massive data collision it cannot be used. The PC should have
one or more network cards only for the sensors.
scanCONTROL 27x0
Page 36

The operation of the sensor via Ethernet does not require any driver installation. However, the network settings have to be done correctly:
-- If more network cards are used, they have to belong to different networks, for example different Class-Csub networks, however they may not belong to the same Class-B sub network.
-- The sensors are supported by an automatically, sensor-adapted IP address in the link-local-net
(169.254.x.x). No collision testing is effected. This is the standard setting, too.
-- The sensor supports the DHCP protocol. This setting is activated by default and has priority over the
retrieval in the link-local-net.
-- A fixed IP address can be given.
-- Various network settings can interfere the connection to the sensor (fo example Firewall or packet filter).
-- We recommend using a packet size of 1024 Bytes/packet (payload) which can be set in the demonstration
program or the sensor SDK.

5.3
Installation Instructions
-- The operating voltage can be supplied both from the FireWire (1394) connection socket of the PC as well
as via a separate power source. In the case of inadvertent double connection, the higher voltage prevails.
-- The operating voltage is protected against reverse polarity.
-- The operating voltage for the scanCONTROL 27x0 measuring device should come from a 24 V power supply which is only used for measuring equipment and not simultaneously for drives, contactors or similar
pulse interference sources.
-- Only use shielded cables for all connection cables. Connector and cable must be matched to each other
for hermetically sealed versions. Paired data cables with colored cores and copper shielding are recommended for self-made cables.
-- Connect the cable shields to the potential equalization on the evaluation unit (switch cabinet, PC case,
connector case) and avoid ground loops.
-- Lay all connection cables in accordance with the generally applicable measuring technology regulations,
i.e. for example not directly next to pulse-carrying lines, preferably in a separate cable duct.
-- The minimum bending radii of the recommended cables for flexible laying must not be less, see Fig. 21.
-- MICRO-EPSILON recommends the use of the optionally available power supply PS2020, DIN rail mounting, input 230 VAC, output 24 VDC/2.5 A.

6.1
Displays
After getting ready for operation, switch on the external direct current power supply (24 VDC).
The state LED indicates different error conditions by flashing. If several errors occur at the same time, it
indicates two of them alternately. Therefore the LED can continue to flash for some time after the rectification
of an error. If no flashing occurs for several seconds, no error has occurred.
i
6.2
The scanCONTROL 27x0 sensor needs a running-in time of typically 20 minutes for high precision measurements.
Operating and Demonstration Programs
A CD-ROM is provided for the operation of the sensor: As well as the installation instructions mentioned
above, the CD-ROM also contains various documentation and programs:
-- The demonstration program “DeveloperDemo.exe” in the directory [CD]:\Program\Developer Demo is
used for scanner parameterization and simple display of profile data. A screenshot of the standalone demonstration program can be seen, see Chap. 6.4.3.
-- The directory [CD]:\Development\SDK contains a sensor-specific DLL and descriptions and examples for
creating your own user programs with the C++ programming language. It can also be used with C, Delphi
or other programming languages. The associated descriptions for the DLL in German and in English can
be found in the same directory.
-- scanCONTROL Configuration Tools is used to analyze typical measurement tasks for scanCONTROL 27x0.

Instructions for Operating
6.4.1
Measuring Field Selection
The optical design of the sensor satisfies the so-called “Scheimpflug condition” which ensures optimum
mapping over the complete measuring range. In doing so, the measuring range is mapped on a rectangular matrix. The distortions resulting from this are shown, see Fig. 22. The usable measuring range is always
trapezoidal.
The assigned maximum x-values for the z-coordinates can be found, see Fig. 8, see Fig. 11, see Fig. 14.
Please refer to the sensor acceptance report of your sensor. A slight range shifting of a measuring field is
possible and depends on the sensor.
The top edge corresponds to the start of the measuring range and the bottom edge to the end of the measuring range. The corners of the read image field are on a grid with grid spacing of 1/8 of the matrix. An image
field change is only possible in this raster.
The sensor matrix used in the scanCONTROL 27x0 supports the reading of a restricted measuring field. The
following picture shows the predefined view areas and the associated measuring fields.
scanCONTROL 27x0

The measuring field can be restricted by omitting complete matrix areas in order to suppress interfering image ranges.
No correlation of the measuring field size to the speed of the reading process can be made.
The following measuring fields are used in the demonstration program, see Chap. 6.2.

Fig. 23 Measuring fields used
Measuring field and measuring range must be clearly differentiated in practical use. The measuring field is
related to the matrix and the measuring range is related to the measuring object (the object space).
Both do not have to match on account of the optical mapping and the definitions.
i
The measuring field “Standard” is larger than the measuring range “Standard”. The minimum dimensions can be found, see Fig. 8, see Fig. 11, see Fig. 14.
The scanCONTROL 27x0 sensors are distinguished by
-- a laser line with 20° opening angle.
-- the receiver has a smaller opening angle (view angle) than the laser line.
-- centered measuring field (symmetrical to the center axis).
-- the high resolution sensor image matrix has 640 x 480 pixels. The measuring field geometry is fixed.
-- reference for the distance (Z-axis) is the lowest body edge of the sensor, see Fig. 8, see Fig. 11, see Fig.
14.
-- Use of the DCAM standard 1.3, however with rededication of the parameters:
ƒƒ camera parameter in triangulation parameters
ƒƒ image in profile
Further information for this can be found in the file “OpManPartB.html” on the CD-ROM.
-- Standard digital video camera driver according to DCAM 1.30 from different manufacturers can be used.

Calibration
The calibration of the sensor is performed using the complete matrix and is independent from the selected
measuring field.
The trapeze form of the measuring field is produced from the projection onto the sensor matrix. The standard
measuring range is framed in the center.
A sensor acceptance report is enclosed for each sensor. Three diagrams for the linearity measurement which
are briefly explained in the report are included in the sensor acceptance report. The key diagram in the sensor acceptance report is shown again below, see Fig. 24.

The picture on the top left and bottom right in the acceptance report show sections through the picture, see
Fig. 24 (blue lines).
Page 47

All measuring points in the center of the measuring range (vertical section where x=0) and bottom right of the
horizontal section, also in the (vertical) center of the measuring range (midrange) are shown on the top left of
the acceptance report.
The measurement error increases at both ends of the depth range and particularly in the remote corners.
These areas should therefore be avoided for the measurement.
6.4.3
Automatic Exposure Time Regulation
The automatic exposure time regulation facilitates the recording of the profile with optimum exposure time
(shutter time). The available brightness information for each point of the profile is used for this.
The “shutter time” preset by the user is used as the starting value for the automatic exposure time regulation.
It should be selected so large that still valid measured values can be output at the darkest place of the profile. One of the supplied demonstration programs can be used for determining this. The automatic exposure
time regulation can also be deactivated if required.
If there is no object in the measuring range, the “shutter time” stored in the shutter register of the sensor will
be used as exposure time. This value must also guarantee reliable recognition of the darkest measurement
object.
A previous test is recommended if the target is very dark or has very high contrast. The various demonstration programs are suitable for adjusting and testing the exposure time. In doing so, it is by all means sensible
to work with several different exposure times and to observe the effect in the diagrams.
The current exposure time can be calculated from the timestamps of the measured values. It is displayed as
“Shutter time”, see Fig. 25.

Error Influences
6.5.1
Reflection Factor of the Target Surface
The sensor basically evaluates the diffuse portion of the laser line reflections. Any statement about a minimum reflection factor is only possible with reservations. A preliminary examination is necessary for using the
sensor on transparent or reflecting objects.
The method of direct reflection on reflecting surfaces as it is successfully applied for the point triangulation
cannot be used for the line triangulation on account of the fan-shaped form of the laser line (central projection). Here, the receiving lens would only be able to reach a narrow area near the center. As usually curved
surfaces should also be measured for the profile measurement, this range will be further narrowed.
6.5.2
Color Differences
Color differences of measurement objects have effects. However, these color differences are often also combined with different penetration depths of the laser light into the material. Different penetration depths in turn
result in apparent changes of the line thickness. Therefore, color changes, combined with penetration depth
changes, can result in inaccurate measurements.
As the exposure parameters can only be changed as a whole for one profile, careful matching of the exposure to the target surface is recommended.
6.5.3
Temperature Influences
A running-in time of at least 20 minutes during start-up is required in order to achieve a uniform temperature
spread in the sensor.
If measurements with accuracy in the μm range are made, the effect of temperature fluctuations on the
mounting must also be observed by the user.
Due to the damping effect of the thermal capacity of the sensor, fast temperature changes are only measured
after a delay.
scanCONTROL 27x0
Page 50

6.5.4
External Light
An interference filter in the sensor is present for suppression of external light. In general, the shielding of
external light directly emitted on the target or reflected in the sensor must be ensured using protective covers
or similar.
Pay particular attention to unwanted reflections of the laser line outside the measuring object range (background, object holder or similar) which can be reflected back again into the view area of the receiver.
Matt black surface coatings are recommended for all objects outside the measuring range (object holders,
transport apparatus, grippers or similar).
6.5.5
Mechanical Vibrations
If high resolutions in the μm range should be achieved with the sensor, particular attention must be paid to
stable or vibration-damped sensor and measuring object mounting.
6.5.6
Surface Roughness
Surface roughness of 5 μm and more results in „surface noises“ due to interference of the laser light.
Direct reflections of the laser light to the receiver can also occur at the finest grooves (e.g. abrasion marks
on the surface) particularly if these run in the line direction. This can result in inaccurate measured values.
Prevention of this effect might be possible by adjusting several sensor settings e.g. exposure time, filter.
scanCONTROL 27x0
Page 51

6.5.7
Shadowing Effects
-- Receiver: The laser line can disappear completely or partially behind steep edges. The receiver then does
not „see“ these areas.
-- Laser line: The fan-shaped form of the laser line inevitably results in partial shadowing at vertical edges. In
order to make these areas visible, only changing the sensor or object position helps.
As a general rule, measuring objects with steep edges cannot be one hundred percent measured using laser
triangulation. The missing areas can only be supplemented or interpolated using suitable software.

6.6
Cleaning
A periodically cleaning of the protective housings is recommended.
Dry cleaning
This requires a suitable optical antistatic brush or blow off the panels with dehumidified, clean and oil free
compressed air.
Wet cleaning
Use a clean, soft, lint-free cloth or lens cleaning paper and pure alcohol (isopropanol) for cleaning the protective housing.
Do not use commercial glass cleaner or other cleansing agents.

Commissioning scanCONTROL Output Unit
After having installed the required wiring of the modules of scanCONTROL Output Unit, you have to parameterize the measurement system according to your measurement task to get the desired signals at the digital
and analog output ports.
Connect the sensor to the PC using the enclosed FireWire or Ethernet cable.
Alternatively, scanCONTROL Output Unit can be connected simultaneously to the PC and to the sensor.
Parameterize the measurement system using scanCONTROL Configuration Tools and assign the desired
signals to the digital and analog output ports.
When the parameterization is finished, save the settings to a user mode of the sensor.
scanCONTROL Configuration Tools > Menu > Parameters > Save parameters to scanCONTROL..
Refer to scanCONTROL Configuration Tools manual, Chapter 3.14.4.
Exit scanCONTROL Configuration Tools and disconnect scanCONTROL 2710, PC and if necessary
scanCONTROL Output Unit.
Connect the sensor to the scanCONTROL Output Unit by using the enclosed FireWire or Ethernet cable.
scanCONTROL 2710 and the output unit operate now as an independent measurement system and the
digital and analog signals are output via the assigned ports.
i
scanCONTROL 27x0
Depending on your system configuration it is possible that scanCONTROL Configuration Tools freezes
if scanCONTROL 2710 and scanCONTROL Output Unit are simultaneously connected to the FireWire
bus. In this case, please exit scanCONTROL Configuration Tools and disconnect the sensor and the
output unit from the FireWire bus. Afterwards you should only connect scanCONTROL 2710 to the PC
and parameterize it. After having saved the parameters to a user mode, please exit scanCONTROL Configuration Tools, disconnect the sensor from the PC and connect it to scanCONTROL Output Unit via
FireWire. Now the digital and analog signals are output via the assigned ports.
