Maintenance and care
The camera system operates maintenance-free. No maintenance is required in order to
ensure compliance with LED risk group RG 1 or RG 2.
NOTE
Repair work on the individual components may only be performed by qualified and
authorized service personnel.
NOTE
Claims under the warranty rendered void
Do not open the device housing.
If the device is opened, any warranty claims against SICK AG will be void.
Checking the incremental encoder
When using an incremental encoder, the position of the friction gear on the drive
technology must be checked regularly.
▸
Ensure that the incremental encoder is in contact with the drive systems and
components and that the friction gear does not slip as it turns.
7.1
Cleaning the camera system
The optical reading performance of the camera system is weakened by scratches or
streaks on the front screen. To achieve the full optical reading performance of the camera
system, the front screen must be regularly checked for contamination or damage. This is
especially true in harsh operating environments (dust, abrasion, humidity, fingerprints,
etc.).
The external deflector mirror is a front surface mirror. This means that cleaning affects the
optical effective area itself.
▸
That is why you should not clean the deflector mirror unless it is necessary.

Cleaning the front screen
Caution
LED light beam
The ICI8x0 line illumination uses LEDs as light source.
Variants with red LEDs (ICI890-0x and ICI890-2x) conform to risk group RG1, variants with
white LEDs (ICI890-3x), blue-white LEDs (ICI890-1x) and blue LEDs (ICI890-4x) conform to
risk group RG2 according to IEC 62471-1: 2006-07/EN 62471-1: 2008-09.
