Maintenance

If the reading window is scratched or damaged (cracked, broken), it must be replaced. Plea-

se contact the SICK Service.

Cleaning the housing

In order to ensure sufficient cooling for the CLV490, make sure that the housing is always

clean.

¾ Use a soft brush to free the housing from dust.

¾ If necessary, clean the LEDs on the rear of the device.

7.2.2 Cleaning other optical surfaces

If an external reading pulse generator and/or object-height detection sensors are used (e.

g. photoelectric reflex switches), further sensors with optical effective surfaces can be instal-

led. Soiling of these surfaces can cause incorrect switching behaviour.

¾ In order to prevent incorrect switching behaviour, remove soiling from the optical effec-

tive surfaces of the external sensors.
