Safety information
2.3.4 LED radiation from the ICI890 Illumination
LED radiation!
The Camera Systems ICR880 and ICR890 are classified in LED risk group RG 1 according
to IEC 62471-1:2006-07/EN 62471-1:2008-09. The illumination type-depending uses
LEDs with red, blue or white light.
The entire window surface is the LED radiation outlet opening.
The accessible radiation from the LEDs does not not represent a risk due to the normal re-
strictions imposed by human behavior. It is not possible to entirely rule out temporary, dis-
orientating optical effects on the human eye (e.g. dazzle, flash blindness, afterimages,
impairment of color vision), in particular in conditions of dim lighting. No safety measures
are required.
Caution — use of controls, adjustments or performance of procedures other than those
specified herein may result in hazardous radiation exposure.
Do not deliberately look directly into the illumination for a lengthy period.
Do not open the housing. (The illumination is not switched off if the housing is opened).
Always observe the latest valid version of optical radiation protection regulations for
photobiological safety of lamps and lamp systems.
Radiation power
The ICI890 Illumination type-depending uses LEDs with the following wavelenghts:
Red light: = 620 nm (amber)
Blue and white light: = 470 nm
The radiation emitted is not harmful to human skin.
Important Maintenance is not required to ensure compliance with LED risk group RG 1.
The ICI890 Illumination operates as follows:
The reading pulse (pulse source) controls the on and off mechanism of the LED illumi-
nation during the reading process. The LEDs are switched on in pulsed mode during
the reading operation depending on the reading gate duration.
A time stage (illumination timeout) automatically switches off the illumination during
the reading operation after 3 seconds (default setting) following the start of a continu-
