Maintenance
The illumination unit is maintenance-free. No maintenance is required in order to ensure
compliance with LED risk group RG 1 or RG 2.
Safety measures for risk group RG 2
If directly looking into the beam for more than 0.25 seconds cannot be ruled out,
eye protection is strongly recommended while handling the product (commissioning,
adjustment, cleaning, etc.).
Warning label for risk group RG 2
Illumination units equipped with LEDs in risk group RG 2 feature the following warning
label:
For the devices, the label is located on the exterior of the housing.
If the device itself is integrated into machinery, for example, in a way which obscures
the warning label attached, additional clearly visible labels should be attached to the
machinery close to where the light is emitted.
Radiated power
Depending on the model, the ICI890 illumination unit works with LEDs with the following
wavelength:
•
Red light: λ
= 630 nm (amber).
•
White light: λ
= 400 nm to 750 nm
•
Blue-
white light: λ
= 470 nm
•
Blue light: λ = 449
nm
The ICI890 illumination unit works as follows:
•
The reading pulse (pulse source) controls the switching on and off of the LED illumina-
tion during the read process. In read mode, the LEDs are switched on in pulse mode
depending on the reading gate duration.
•
In read mode, a time stage (illumination timeout) automatically switches off the
illumination 3 seconds (default) after a continuous reading pulse has started, but does
not end the reading pulse. The reading pulse must be ended with a corresponding
clock signal. The next reading pulse switches the illumination back on.
•
The illumination timeout can either be set or switched off in the range of 3 s ... 25 h.
For safety reasons, the maximum switch-on time of the illumination is 3 seconds.
