NOTE
Static charge causes dust particles to adhere to the reading window. This effect can be
avoided by using an anti-static glass cleaner in combination with the SICK lens cloth
(can be obtained from
).
Cleaning procedure:
CAUTION
Optical radiation: Laser class 2
The human eye is not at risk when briefly exposed to the radiation for up to 0.25 sec‐
onds. 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 com‐
missioning 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 will not switch off the laser. Open‐
ing 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 possi‐
ble, use suitable laser protection goggles. These must absorb radiation of the devi‐
ce's wavelength effectively.
b
Glass lens: Remove dust from the reading window using a soft, clean brush. If nec‐
essary, also clean the reading window with a clean, damp, lint-free cloth, and a
mild anti-static glass cleaning agent.
b
Plastic lens: Clean the reading window only with a clean, damp, lint-free cloth, and
a mild anti-static glass cleaning agent.
NOTE
If the reading window is scratched or damaged (cracked or broken), the lens must be
replaced. Contact SICK Service to arrange this.
Cleaning the housing
In order to ensure that heat is adequately dissipated, the housing surface must be kept
clean.
b
Clear the build up of dust on the housing with a soft brush.
9.2.2
Cleaning surfaces that have an optical effect
Depending on how the reading station is equipped, additional local sensors may have
other surfaces with an optical effect installed (e.g. single-beam photoelectric safety
switches for an external reading pulse). Contamination on these sensors can result in
faulty switching behavior.
