NOTE
Static charging may cause dust particles to stick to the viewing window. This effect can
be avoided by using an anti-static cleaning agent in combination with the SICK lens
cloth (part no. 4003353) (can be obtained from www.sick.com).
The viewing window is made of glass, see "Technical data", page 61.
Cleaning procedure:
CAUTION
Optical radiation: Class 2 Laser Product
The human eye is not at risk when briefly exposed to the radiation for up to 0.25
seconds. Exposure to the laser beam for longer periods of time may cause damage to
the retina. The laser radiation is harmless to human skin.
■
Do not look into the laser beam intentionally.
■
Never point the laser beam at people's eyes.
■
If it is not possible to avoid looking directly into the laser beam, e.g., during
commissioning and maintenance work, suitable eye protection must be worn.
■
Avoid laser beam reflections caused by reflective surfaces. Be particularly careful
during mounting and alignment work.
■
Do not open the housing. Opening the housing may increase the level of risk.
■
Current national regulations regarding laser protection must be observed.
b
Switch off the device for the duration of the cleaning operation. If this is not
possible, wear suitable laser safety goggles. These must absorb radiation of the
device’s wavelength effectively.
b
Glass window: remove dust from the viewing window using a soft, clean brush. If
necessary, also clean the viewing window with a clean, damp, lint-free cloth, and a
mild anti-static lens cleaning fluid.
b
Plastic window: 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.
b
Clear the build up of dust on the housing with a soft brush.
Cleaning other, optically effective surfaces
Depending on the equipment of the reading station, additional local sensors with
optically effective areas may be installed (e.g. photoelectric sensor for external read
cycle). Contamination on these sensors can result in faulty switching behavior.
