Quick Start Guide

Laser displacement sensor with both analog and discrete (switched) out puts 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: Not To Be Used for Personnel Protection Never use this device as a sensing device for personnel protection. Doin g so could lead to serious injury or death. This device does not include the self-checking redundant circuitry nece ssary to allow its use in personnel safety applications. A sensor failure or m alfunction can cause either an energized or de-energized sensor output condition.

Features and Indicators

Figure 1. LE Analog Sensor Features

Three LED indicators provide ongoing indication of the sensing status.

Analog Output LED Indicator

Solid Amber = Displayed distance is within the taught analog output window Off = Displayed distance is outside the taught analog output window

Power LED Indicator

Solid Green = Normal operation, power On and laser On Flashing Green (1 Hz) = Power On and laser Off (laser enable mode)

Discrete Output LED Indicator

Solid Amber = Discrete Output is On

Off = Discrete Output is Off

Laser Description and Safety InformationCAUTION: Use of controls or adjustments or performance of procedures other than t

hose specified herein may result in hazardous radiation exposure. Do not attempt to dis assemble this sensor for repair. A defective unit must be returned to the manufacturer. Class 2 Laser Models Laser light can damage your eyes. Avoid placing any mirror-like object in the beam. Never use a mirror as a retr oreflective 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 pract ical. • Terminate the beam emitted by the laser product at the end of its useful path.

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 resp onses, including the blink reflex. This reaction may be expected to provide ade quate protection under reasonably foreseeable conditions of operation, includi ng the use of optical instruments for intrabeam viewing.Figure 2. FDA (CDRH) warning label (Class 2)Class 2 Laser Safety Notes Low-power lasers are, by definition, incapable of causing eye injury wit hin the duration of a blink (aversion response) of 0.25 seconds. They also mus t emit only visible wavelengths (400 to 700 nm). Therefore, an ocular hazard may e xist only if individuals overcome their natural aversion to bright light and stare di rectly into the laser beam.

Class 1 Laser Models

Class 1 lasers are lasers that are safe under reasonably foreseeable con ditions of operation, including the use of optical instruments for intrabeam viewin g.

Figure 3. FDA (CDRH) warning label

(Class 1)Laser wavelength: 650 nmOutput: < 0.22 mWPulse Duration: 150 µs to900 µs Sensor InstallationNOTE: Handle the sensor with care during installation and operation. Sensor wi ndows soiled byfingerprints, dust, water, oil, etc. may create stray light that may deg

rade the peak performance of thesensor. 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 sensi ng. See the following figures for examples of correct and incorrect sensor-to-object orientation as certain placements may pose problems for sensing distances.

Sensor Mounting

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 equ

ipment at the desired location. Do not tighten at this time.

3. Check the sensor alignment.

4. Tighten the screws to secure the sensor (or the sensor and the bracket)

in the aligned position.

Down and Up Buttons

Press Down

and Up to: • Access the Quick Menu from Run mode • Navigate the menu systems • Change programming settings When navigating the menu systems, the menu items loop. Press Down and Up to change setting values. Press and hold the buttons to cycle through n umeric values. After changing a setting value, it slowly flashes until the change is sa ved 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 check mark 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 MenuImportant: Pressing Escape discards any unsaved programming changes.

In the Sensor Menu, a return arrow Escape

returns to the parent menu.

Press and hold Escape

for 2 seconds to return to Run mode from any menu or remote teach. Sensor ProgrammingProgram 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 M enu. See Quick Menu on page 5,

Sensor

Menu (MENU) on page 6, 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 t he buttons for security, preventing unauthorized or accidental programming changes. See the instruction manual for more information.
