LE250 and LE550 Analog-Discrete Laser Gauging L- GAGE® Sensor Quick Start Guide 

## Product Description 

Laser displacement sensor with both analog and discrete (switched) outputs 

This guide is designed to help you set up and install the L-GAGE® LE Laser Gauging Sensor. For complete information on programming, performance, troubleshooting, dimensions, and accessories, please refer to the Instruction Manual at www.bannerengineering.com. Search for p/n 175094 to view the manual. Use of this document assumes familiarity with pertinent industry standards and practices. 

## WARNING: 

- Do not use this device for personnel protection 

- Using this device for personnel protection could result in serious injury or death. 

- This device does not include the self-checking redundant circuitry necessary to allow its use in personnel safety applications. A device failure or malfunction can cause either an energized (on) or de-energized (off) output condition.

## 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. 

## Sensor Orientation 

Correct sensor-to-object orientation is important to ensure proper sensing. See the following figures for examples of correct and incorrect sensor-to-object orientation as certain placements may pose problems for sensing distances.

Applying tilt to sensor may improve performance on reflective targets. The direction and magnitude of the tilt depends on the application, but a 15° tilt is often sufficient. 

## 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.

Press Down and Up to change setting values. Press and hold the buttons to cycle through numeric values. After changing a setting value, it slowly flashes until the change is saved using the Enter button. 

Enter Button 

- Press Enter to: • Access the Sensor Menu from Run mode • Access the submenus • Save changes 

In the Sensor Menu, a checkmark in the lower right corner of the display indicates that pressing Enter accesses a submenu. 

Press Enter to save changes. New values flash rapidly and the sensor returns to the parent menu. 

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. 

## LE Laser 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 3, "Sensor Menu (MENU)" on page 4, and the instruction manual (p/n 175094) 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.

**CLASS 1 LASER PRODUCT** 

- 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. 

- 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. 

- CAUTION: • Ne regardez jamais directement la lentille du capteur. • La lumière laser peut endommager la vision. • Évitez de placer un objet réfléchissant (de type miroir) dans la trajectoire du faisceau. N'utilisez jamais de miroir comme cible rétro-réfléchissante. 

- CAUTION: • Tout dispositif défectueux doit être renvoyé au fabricant. • L'utilisation de commandes, de réglages ou de procédures autres que celles décrites dans le présent document peut entraîner une exposition dangereuse aux radiations.

For safe laser use: 

- 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.

## Class 2 Laser Description and Safety Information 

- Laser light. Do not stare into the beam. **CLASS 2** 

- Complies with 21 CFR 1040.10 and 1040.11 except for deviations **LASER PRODUCT** pursuant to Laser Notice No. 56, dated May 8, 2019. LJ 

- 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. 

- 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.

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. 

Complies with IEC 60825-1:2014 and EN 60825-1:2014+A11:2021. 

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 nm 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. 

For safe laser use: 

- 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. 

IMPORTANT: This laser device is not bore-sighted.
