1.3 Laser Description and Safety Information

CAUTION: 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.

1.3 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.

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.

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.

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 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.

Figure 5. Orientation by a wall

Figure 8. Orientation for a height difference

Figure 6. Orientation in an opening

Figure 9. Orientation for a color or luster

difference

Figure 7. Orientation for a turning object

Figure 10. Orientation for a highly reflective

target

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.

2.2 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 location. Do not tighten
the mounting screws at this time.

3. Check the sensor alignment.

4. Tighten the mounting screws to secure the sensor (or the sensor and the bracket) in the aligned position.

3.5.2 Midpoint TEACH

The Midpoint TEACH uses both the window size and the
TEACH midpoint to determine the actual measurement
window. For example, a window of 200 mm with a midpoint
of 600 mm places the measurement window from 500 mm to
700 mm.

To use Midpoint TEACH:

1. Set the window size.

2. Set the measurement window using TEACH Midpoint

3.5.8 Switch Point Reference (SPtRef)

The SPtRef menu only displays for a discrete output when it is set to switch mode. The SPtRef settings, object or
background, for the two discrete outputs are set independently. This setting cannot be changed with remote teach.

• Object (default). Object mode sets the switching threshold just past the location of the taught object, farther away
from the sensor's face.

• Background. Background mode sets the switching threshold in front of the taught object, closer to the sensor's
face.

• Custom. Custom mode allows the user to define the location of the switching threshold relative to a taught
distance using the Offset menu that appears only after selecting Custom Switch Point Reference.

The distance between the surface of the taught object and the switching threshold varies depending on measurement
strength and can be affected by target distance, color, reflectivity, etc. Use object mode when teaching an object if a
change in state is required when the object is no longer present. Use background mode when teaching background so that
the output state changes when a new object is in front of the background.

Navigate: MENU > Dx_OUT > SPtRef
Remote Input: Not available
Default: Object

3.5.9 Switch Point TEACH Offset

Use this menu to set an offset from the taught distance after a switch point TEACH, if SPtRef is set to Custom.
By default, the value is 0 mm. A positive offset value always shifts the threshold towards the sensor.

4 Sync Master/Slave

Two LE250/550 Laser sensors may be used together in a single sensing application. To eliminate crosstalk between the
two sensors, configure one sensor to be the master and one to be the slave. In this mode, the sensors alternate taking
measurements and the response speed doubles.

1. Configure the first sensor as the master; navigate: MENU > INPUT > Type > SyncMstr.

2. Configure the second sensor as the slave; navigate: MENU > INPUT > Type > SyncSlve.

3. Connect the gray (input) wires of the two sensors together.

If using a combination of Class 1 and Class 2 laser models, the Class 1 laser model must be used as the master.

The TEACH failed. The target is in range but
the offset value caused the setpoint(s) to
be out of range.

The adjusted or taught window size is too
small; the minimum window size is
displayed.

sensor is not measuring.
The sensor input is set to laser enable and

the input is not active.
The laser shut off, the Power LED flashes

red and Output LEDs flash amber at 1Hz,
and the display is blank.

The laser has experienced a fault.
One of the switch points is located outside

the sensor's range, either too close to the
sensor or too far away.

The slave mode sensor does not see the
master's pulse.

Adjust the offset value or target distance to keep
the setpoint(s) within the measurement range.

The sensor automatically adjusts the window size
to maintain the minimum window size and
completes the adjust or TEACH operation.

Move the target within the measurement range.

See Input Type on page 21.

Contact Banner Engineering to resolve.

The desired window size is maintained, but the
usable portion of the window is restricted to be
within the sensor's range.

Verify the master mode sensor is configured and
functioning properly. Check the input wire
connection between the master and slave.
