The viewing window lens must be kept clean and dry during operation.
NOTE
Static charging may cause dust particles to stick to the viewing window. This effect can
be reduced by using an anti-static cleaning agent in combination with the SICK lens
cloth (part number 4003353) (can be obtained from
The viewing window is made of plastic,
.
Cleaning procedure:
CAUTION
Optical radiation: LED risk group 1, visible radiation, 400 nm to 780 nm
The LEDs may pose a danger to the eyes in the event of incorrect use.
■
Do not look into the light source intentionally.
■
Do not open the housing. Opening the housing will not switch off the light source.
Opening the housing may increase the level of risk.
■
Comply with the current national regulations on photobiological security of lamps
and lamp systems.
If the product is operated in conjunction with external illumination systems, the risks
described here may be exceeded. This must be taken into consideration by users on a
case-by-case basis.
CAUTION
Optical radiation: Class 1 Laser Product
The accessible radiation does not pose a danger when viewed directly for up to 100
seconds. It may pose a danger to the eyes and skin in the event of incorrect use.
■
Do not open the housing. Opening the housing may increase the level of risk.
■
Current national regulations regarding laser protection must be observed.
For both radiation types:
It is not possible to entirely rule out temporary disorienting optical effects, particularly
in conditions of dim lighting. Disorienting optical effects may come in the form of
dazzle, flash blindness, afterimages, photosensitive epilepsy, or impairment of color
vision, for example.
b
Switch off the device for the duration of the cleaning operation. If this is not
possible, use suitable laser protection goggles. These must absorb radiation of the
device’s wavelength effectively.
b
Clean the viewing window only with a clean, damp, lint-free cloth, and a mild
anti-static lens cleaning fluid.
NOTICE
If the inspection window is scratched or damaged (cracked or broken), the lens must be
replaced. Contact SICK Support to arrange this.
■
If the inspection window is cracked or broken, take the device out of operation
immediately for safety reasons and have it repaired by SICK.
Cleaning the housing
In order to ensure that heat is adequately dissipated from the device, the housing
surface must be kept clean.
