2.1 Photobiological safety
The device classification according to EN 62471 is based on a distance of the viewer from the light
source of 200 mm for the most unfavourable device configuration (colour, exposure time, frame rate).
Under application-specific conditions, the risk for the viewer may differ depending on the installation
situation and the device settings.
The system architect/operator is required to carry out a hazard analysis and to take appropriate
measures for the protection of persons. In particular national regulations also have to be adhered to.
Possible protective measures may include screens, guaranteed minimum distances of a viewer,
access controls, safety glasses and user training.
It is generally recommended not to look directly into the switched-on light source. Glare or irritation
can also occur in Risk Group 0 (Exempt Group). Ideally, the device is installed in such a way as to
prevent eye exposure to the light source.
2.1.1 O2D540, O2D542
The colour of the illumination LEDs can be switched between red (625 nm), green (525 nm), blue
(453 nm) and white. The colour selection applies to all LEDs at the same time.
The unit complies with Risk Group 1 according to EN 62471:2008.
Reducing the risk for the viewer to equal that of the Exempt Group (RG 0):
u
When selecting the blue and white LEDs, observe the distances between the light source and the
