Class 2 Lasers
Class 2 lasers are lasers that emit visible radiaon in the wavelength range from 400 nm to
700 nm, where eye protecon is normally aorded by aversion responses, including the blink
reex. This reacon may be expected to provide adequate protecon under reasonably
foreseeable condions of operaon, including the use of opcal instruments for intrabeam
viewing.

Class 2 Laser Safety Notes
Low-power lasers are, by denion, incapable of causing eye injury within the duraon of a
blink (aversion response) of 0.25 seconds. They also must emit only visible wavelengths (400
to 700 nm). Therefore, an ocular hazard may exist only if individuals overcome their natural
aversion to bright light and stare directly into the laser beam.
Sensor Installaon
Note: Handle the sensor with care during
installaon and operaon. Sensor windows soiled by ngerprints, dust,
water, oil, etc. may create stray light that may degrade the peak performance of the sensor. Blow the window clear
using ltered, compressed air, then clean as necessary using 70% isopropyl alcohol and coon swabs or water and a
so cloth.
Mount the Sensor
1. If a bracket is needed, mount the sensor onto the bracket.
2. Mount the sensor (or the sensor and the bracket) to the machine or equipment at the desired locaon. Do not ghten the
mounng screws at this me.
3. Check the sensor alignment.
4. Tighten the mounng screws to secure the sensor (or the sensor and the bracket) in the aligned posion.

Sensor Programming
Program the sensor using the buons on the sensor or the remote input (limited programming opons).
From Run mode, use the buons to access the Quick Menu and the Sensor Menu. See Quick Menu on page 4, Sensor Menu (MENU)
on page 4, and the instrucon manual (p/n 194135) for more informaon on the opons available from each menu. For TEACH
opons, follow the TEACH instrucons in the instrucon manual.
In
addion to programming the sensor, use the remote input to disable the buons for security, prevenng unauthorized or accidental
programming changes. See the instrucon manual for more informaon.
