Laser Description and Safety Information
CAUTION:
· Return defective units to the manufacturer. · Use of controls or adjustments or performance of procedures other than those specified herein may result in
hazardous radiation exposure. · Do not attempt to disassemble this sensor for repair. A defective unit must be returned to the manufacturer.
Class 2 Laser Models
CAUTION: · Never stare directly into the sensor lens. · Laser light can damage your eyes. · Avoid placing any mirror-like object in the beam. Never use a mirror as a retroreflective target.
For Safe Laser Use - Class 2 Lasers · Do not stare at the laser. · Do not point the laser at a person's eye. · Mount open laser beam paths either above or below eye level, where practical. · Terminate the beam emitted by the laser product at the end of its useful path.
Reference IEC 60825-1:2007, Section 8.2.

LTF Time of Flight Laser Distance Sensor Quick Start Guide
Continued from page 2
Class 2 Lasers Class 2 lasers are lasers that emit visible radiation in the wavelength range from 400 nm to 700 nm, where eye protection is normally afforded by aversion responses, including the blink reflex. This reaction may be expected to provide adequate protection under reasonably foreseeable conditions of operation, including the use of optical instruments for intrabeam viewing.
FDA (CDRH) warning label (Class 2)
Class 2 Laser Safety Notes Low-power lasers are, by definition, incapable of causing eye injury within the duration 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 Installation
NOTE: Handle the sensor with care during installation and operation. Sensor windows soiled by fingerprints, dust, water, oil, etc. may create stray light that may degrade the peak performance of the sensor. Blow the window clear using filtered, compressed air, then clean as necessary using 70% isopropyl alcohol and cotton swabs or water and a soft cloth.
Mount the Device
1. If a bracket is needed, mount the device onto the bracket. 2. Mount the device (or the device and the bracket) to the machine or equipment at the desired location. Do not tighten the mounting
screws at this time. 3. Check the device alignment. 4. Tighten the mounting screws to secure the device (or the device and the bracket) in the aligned position.

Sensor Programming
Program the sensor using the buttons on the sensor or the remote input (limited programming options).
From Run mode, use the buttons to access the Quick Menu and the Sensor Menu. See "Quick Menu " on page 4, Key definition for "{keyrefName}" not found in the DITA map., and the instruction manual (p/n 194135) for more information on the options available from each menu. For TEACH options, follow the TEACH instructions in the instruction manual.
In addition to programming the sensor, use the remote input to disable the buttons for security, preventing unauthorized or accidental programming changes. See the instruction manual for more information.
