Care and maintenance
The L4000 system is maintenance-free. The lenses for the sensors
must be cleaned regularly or if dirty.
Avoid scratching the lenses and the formation of droplets on the
lenses as these could change the optical properties.
= Do not use aggressive cleaning agents.
= Do not use abrasive cleaning agents.
Static charges cause dust particles to be attracted to the lens. You
can prevent this effect by using the antistatic plastic cleaner (SICK-
Part No. 5 600 006) and the SICK lens cloth (Part No. 4 003 353).
How to clean the lens:
= Use a clean and soft brush to remove dust from the lens.
= Then wipe the lens with a clean and damp cloth.
After cleaning, check the position of sender and receiver to make
sure that it is not possible to climb over, creep below or stand behind
the protective device.
= Check the effectiveness of the protective device as described in
chapter 6.3 "Test notes" on page 93.
