10.2 Replacing the optics cover
P
erform an optics cover calibration with the aid of the CDS after the replacement of the
optics cover!
The level of contamination is measured continuously during the operation of the S300. For
this purpose the optics cover calibration must first be performed; this then serves as a
reference for the contamination measurement (status = not contaminated).
The optics cover calibration is only allowed to be performed with a new optics cover! The
new optics cover must be free of contamination at the time of the optics cover calibration.
The optics cover calibration must be performed at room temperature (10-30 °C)!
If the optics cover is scratched or damaged, you must replace the optics cover. Order the
replacement optics cover from SICK (see section 13.3 “Accessories/spare parts” on
page 135).
The optics cover on the S300 is an optical part that must not be soiled or scratched on
replacement.
The optics cover is only allowed to be replaced by specialist personnel in a dust and dirt-
free environment.
Never replace the optics cover during ongoing operation, as internal parts may be irrepa-
rably damaged in certain circumstances and dust particles may enter the device.
It is imperative that you avoid contamination of the inside, e.g. with fingerprints.
Do not use any additional sealant for sealing the optics cover, e.g. silicon, as these
substances may affect the optics.
Mount the optics cover as per the following instructions to ensure that the housing is
sealed to IP 65.
How to replace the optics cover:
Only use a new optics cover (see 13.3.9 on page 138).
When replacing the optics cover, take ESD protection measures.
Set a torque wrench to 1.2 Nm (hand-tight) and have this at hand.
Disconnect the system plug and remove the S300.
Take the S300 to a clean place (office, repair shop or similar).
First clean the outside of the S300. This prevents foreign bodies entering the device
when it is opened.
Undo the fixing screws to for the optics cover.
