Maintenance
7.1
Maintenance during operation
The CLV490 functions maintenance free. Regular maintenance is not required to guarantee
laser class 2 of the CLV490.
Note
Don’t open the device. The warranty will be forfeited if the device is opened.
The CLV indicates any faults or malfunctions by outputting coded system and error messa-
ges (e. g. "CLV SYS-Failure: 081") via its auxiliary interface. The messages are displayed in
the "CLV-Setup" program window in the fourth field from the left on the bottom, in the status
line (see also
Chapter 8.3 Error messages, Page 8-2
). CLV-Setup logs the messages in a
file.
7.2
Cleaning the CLV490
Recommendation
In order to make use of the full optical reading capacity of the CLV490, the reading window
should be checked regularly (e. g. weekly) for soiling. This is especially recommended when
operating the device in harsh conditions (dust, abrasion, humidity, finger prints, etc.).
7.2.1
Cleaning the front window
Laser beam can cause blindness.
The CLV490 uses a class 2 red-light laser. Looking directly at the laser beam can
seriously damage your eyesight.
¾
Never look directly into the path of the beam (similar to sunlight).
¾
Switch off the device while it is being cleaned.
¾
Never look directly into the reading window while the device is in operation.
Damage on the reading window
The reading window is made of glass. Scratches and streaks on the window will reduce the
reading performance.
¾
Do not use aggressive cleaning agents.
¾
Do not use cleaning agents which cause increased abrasion (e. g. powder).
¾
Avoid cleaning motions at the reading window which could cause scratches or abrasion
Cleaning the reading window:
Note
Electrostatic charges cause dust particles to stick to the reading window.
This effect can be combated by using anti-static SICK synthetic cleaner (no. 5600006) in
combination with a SICK lens cloth (no. 4003353).
¾
Use a clean, soft brush to free the reading window (
) from dust.
¾
If necessary, additionally clean the reading window with a clean, damp, lint-free cloth
and a mild, anti-static window cleaning fluid.
