PRODUCT DESCRIPTION
1.3. 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 haz-
ardous radiation exposure.
• Do not attempt to disassemble this sensor for repair. A defective unit must be returned to the manufacturer.
1.3.1. 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.
Escape Button
Press Escape to:
• Leave the current menu and return to the parent menu
• Return to Run mode from the Quick Menu
IMPORTANT: Pressing Escape discards any unsaved programming changes.
In the Sensor Menu, a return arrow in the upper left corner of the display indicates that pressing Escape returns to the parent menu.
Press and hold Escape for 2 seconds to return to Run mode from any menu or remote teach.
A lock symbol displays in the upper left corner of the display to indicate when the sensor is locked.
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.
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.
Figure 3: 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
2. 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.
2.1. 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.
2.2. Wiring Diagrams
2.3. Connecting to RSD1
The following diagram depicts the connection of the LTF to the optional RSD1 accessory.
Figure 3: LTF to RSD1

SENSOR PROGRAMMING
3. 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 for the LTF and Sensor Menu (MENU) for
more information on the options available from each menu. For TEACH options, follow the TEACH instructions.
In addition to programming the sensor, use the remote input to disable the buttons for security, preventing unauthorized or accidental program-
ming changes. See Remote Input for more information.
3.1. Quick Menu
The sensor includes a Quick Menu with easy access to view and change the analog and discrete output switch points. Access the Quick Menu
by pressing Down or Up from Run mode. When in the Quick Menu, the current distance measurement displays on the first line and the menu
name and the analog value alternate on the second line of the display. Press Enter to access the switch points. Press Down and Up to change
each digit. Press Enter to move right one digit. After reviewing each digit, press Enter again to save the new value and return to the Quick Menu.
Press Cancel to ignore any changes made if only some digits have been changed.
Figure 2: Quick Menu Map (Window Mode)
3.2. LTF Sensor Menu (MENU)
Access the Sensor Menu by pressing Enter from Run mode. The Sensor Menu is also accessible from the Quick Menu: navigate to MENU and
press Enter. The Sensor Menu includes several submenus that provide access to view and change sensor settings and to view sensor informa-
tion.

See Sensor Menu Full Map and the Menu sections of this manual for more information.
3.3. Remote Input
Use the remote input to program the sensor remotely. The remove input is disabled by default. Activate remote input using the buttons to navigate
to the Input Type menu option.
The remote input provides limited programming options and is Active Low by default. For Active Low, connect the gray input wire to ground (0 V
DC), with a remote switch connected between the wire and ground. To use the Active High function, configure the sensor for Active High using
the buttons on the sensor, then connect the gray input wire to V+ (12 to 30 V DC). Pulse the remote input according to the diagram and the
instructions provided in this manual.
The length of the individual programming pulses is equal to the value T: 0.04 seconds ≤ T ≤ 0.8 seconds.
Exit remote programming modes by holding the remote input low for > 2 seconds, or waiting for the automatic 60-second timeout, or by pressing
and holding Escape for 2 seconds. The sensor returns to Run mode without saving any new settings.
