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®.

23 3
Fig.1: Installation of the device
1 Unit 2 Field of view of the device
3 Area adjacent to the field of view
Mounting the unit:
uDo not place any objects in area (3).
wThis avoids disturbing contours and possible measurement errors.
uAvoid transparent panes in the viewing area of the unit (2).
wEven a very clean glass plate reflects some of the light. This means that measurement errors
are possible.
uUse strain reliefs for all cables connected to the device.
uConnect the housing of the device and the OVP8xx image processing system to the same earth.
wIf no connection to the same earth is possible: mount both units isolated from the earth.
uAvoid installation in heavily polluted environments.
uConsider the installation tolerances when selecting an installation location.
Measurement errors when using the unit
uFollow the instructions.
wIf the instructions are ignored, measurement errors are possible when using the unit.
4.1 Preparing the set-up
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.
uAdapt operating mode and parameters.
uUse a contact protection for the device.

Reducing the surface temperature
To reduce the surface temperature of the device:
uMount the device on heat-conductive metal parts.
wA large-surface contact of the device with metal parts increases heat dissipation (e.g. conventional
aluminium heat sinks or profiles).
uReduce obstructions around the device. Reduce the density of objects mounted near the device.
wObstructions around the device and a high installation density may have a negative impact on
convection (air movement).

5 Electrical connection
ATTENTION
The unit must be connected by a qualified electrician.
Protection class III (PC III) unit (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 unit (see data sheet).
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. The
separation of external circuits must comply with IEC61010-2-201, Figure 102.
uDisconnect power before connecting the unit.
uUse a maximum cable length of 20 m for the coaxial lines to the sensor ports.
wLonger coaxial cables will dampen the signal too much.
ATTENTION
Units 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 units.
uConnect a camera head to only one vision system.
When the camera head is connected to an image processing system:
uObserve the operating instructions of the vision system.
Observe when connecting the unit:
uUse strain reliefs for cables connected to the unit.
