Beam Attenuator - MICRO-EPSILON scanCONTROL 25 Series Assembly Instructions Manual

Laser Class 3B
The sensors with the /3B option fall within laser class 3B. The laser is operated on a
pulsed mode, the maximum optical power is ≤ 50 mW.
Attach the following warning labels to the cover (front and rear side) of the sensor
housing:
Laser warning sign and laser label, LLT25xx-25, LLT25xx-50, LLT25xx-100
COMPLIES WITH 21 CFR 1040.10 AND 1040.11
EXCEPT FOR CONFORMANCE WITH
IEC 60825-1 ED. 3., AS DESCRIBED IN
LASER NOTICE NO. 56, DATED MAY 8, 2019
Class 3B laser sensors are notifiable and a laser protection officer is required.
Mark the laser area recognizable and everlasting. During operation the laser area has
to be restricted and marked.
i
Sensors of laser class 3B requiry an external key switch to switch off the laser, see
operating instructions Chap. 5.2.6.

Beam attenuator

Laser products certified as Class 3B products (EN 60825-1) require a beam attenuator,
other then the key-operated control. The beam attenuator prevents access to all laser
and collateral radiation.
Sensor with close beam
attenuator
To open or close the aperture please follow the steps below:
Loosen the knurled screw
Change the attenuator position and tighten the knurled screw.
The laser aperture must be open during measurement. Please observe the notes on
external laser switching, see operaring instructions Chap. 5.2.6.
