Care and maintenance
The C4000 Select safety light curtain is maintenance-free. The front screen of the C4000
Select safety light curtain and any additional front screen(s) (see “Additional front screen
(weld spark guard)” on page 93) should be cleaned at regular intervals and when dirty.
Do not use aggressive cleaning agents.
Do not use abrasive cleaning agents.
Note
Static charges cause dust particles to be attracted to the front screen. You can prevent
this effect by using the antistatic plastic cleaner (SICK part number 5600006) and the
SICK lens cloth (part number 4003353).
How to clean the front screen and/or the additional front screen (optional extra):
Use a clean and soft brush to remove dust from the front screen.
Then wipe the front screen with a clean and damp cloth.
Note
After cleaning, check the position of sender and receiver to make sure that the
protective device cannot be bypassed (reaching over, under or around).
Verify the effectiveness of the protective device as described in chapter 7.3 “Test
notes” on page 58.
Only factory authorized personnel may repair C4000 Select devices!
