3 Intended use
The unit features a TOF (Time Of Flight) camera and, additionally, an RGB camera.
The TOF camera measures the distance between the camera and the object for each pixel by means
of the time-of-flight principle. For this purpose, the objects are illuminated with the internal infrared light
source.
The RGB camera uses ambient light to capture a colour image of the objects. The infrared light of the
TOF camera is not visible to the RGB camera.
The image processing system OVPxxx is additionally required to use the unit.
3.1 Application area
The device safety is rated for use under the following operating conditions according to EN IEC
61010-2-201:
• indoor use
• altitudes up to 4000 m
• relative air humidity up to max. 90%, non condensing
• pollution degree 2
Electromagnetic compatibility (EMC):
The unit is designed for use in industrial environments.
This product may cause radio interference in domestic areas.
uIf required, take appropriate EMC screening measures.
The IP rating has not been evaluated by UL® Underwriters Laboratories®.

Fig.1: Installation of the device
1 Device 2 Field of view and illumination range of the device
3 Area to be kept free 4 Area without requirements
Installing the device:
uDo not place any objects in area (3).
wObjects in area (3) can cause measurement errors.
wObjects in area (4) are not a problem.
uAvoid transparent panes in the field of view and illumination range of the device (2).
wEven a very clean glass plate reflects some of the light. This means that measurement errors
are possible.
uInstall the device on heat-conductive metal parts or fixtures.
uAvoid installation in heavily polluted environments.
uConsider the installation tolerances when selecting an installation location.
Measurement errors when using the device
uFollow the instructions.
wIf the instructions are ignored, measurement errors are possible when using the device.
For cable lengths over 3 m between the device and the image processing system OVPxxx,
electrical insulation of the device is necessary.
uElectrically isolate the device from the earth.
wFor example, anodising or a coated mounting fixture can be used for insulation.

4.1 Heat management
ATTENTION
The device can heat up depending on the operating mode, the set parameters and the heat
dissipation to the environment.
The difference between the device’s surface temperature and the ambient temperature
must not exceed 25 degrees (according to IEC61010-2-201).
uReduce the surface temperature.
uAdjust the operating mode and the parameters.
The device develops a thermal power loss of up to 8 W, depending on the exposure time and frame
rate set (Ò Technical data).
uDesign a mounting fixture that can dissipate the thermal power loss.
wThe mounting fixture must meet the following properties:
- thermal connection with a thermal resistance < 2.5 K/W,
- cooling surface of > 10x10 cm,
- good heat-conducting material, for example aluminium.
uEnsure sufficient convection on the device and mounting fixtures.
wObstructions around the device and a high installation density may have a negative impact on
convection.
uReduce the exposure time or frame rate.
wThe surface temperature decreases if the parameters are reduced.

5 Electrical connection
The device must be connected by a qualified electrician.
uDisconnect power before connecting the device.
uUse strain reliefs for cables connected to the device.
Protection class III device (IEC 61010-2-201 chap. 6.5.2.101.4).
The electrical supply must
• be provided only by PELV circuits (IEC 61010-2-201 chap. 3.111),
• not exceed 35 V DC during operation,
• not exceed 60 V DC in the event of a single fault and
• not exceed the permitted operating voltage of the device (see data sheet).
The separation of external circuits must comply with IEC61010-2-201, Figure 102.
WARNING
Unsuitable power supply
wElectric shock may cause serious injury or death.
uUse a PELV power supply within the specified voltage range.
Use energy-limited circuits for the electrical supply (IEC 61010-1 chap. 9.4). The energy of the circuit
can be limited at an operating voltage of 24 V by an overcurrent protection device. The overcurrent
protection device must switch off a current of 8.3A in maximum 120s. Observe the specific tripping
characteristic. Possible overcurrent protection devices:
• fuse or
• non-adjustable and non-self-reclosing electromechanical device.
Separate the circuit from other, non-energy-limited circuits by at least basic insulation.
ATTENTION
No suitable energy limitation of the circuit
wFire hazard in case of a malfunction.
uUse energy-limited circuit according to IEC 61010-1 chap. 9.4.
ATTENTION
Devices damaged due to overload
wA camera head has 2 connections. If both connections are connected to different image
processing systems at the same time, an overload will occur. This will damage the
devices.
uConnect a camera head to only one image processing system.
High signal damping due to long coaxial cables
uUse a maximum cable length of 20 m for the coaxial lines to the sensor ports.
When the camera head is connected to an image processing system:
uObserve the operating instructions of the image processing system.
