CAUTION
Use of controls or adjustments or the performance of procedures other
than those specified herein may result in hazardous radiation exposure.
Class IIIb/3R Laser Products
WARNING
Follow the instructions mentioned in this manual. Otherwise, injury to the
human body (eyes and skin) may result.
•
Do not directly look at or touch the laser beam and its reflection from a
mirror-like surface.
• Do not direct the beam at other people or into areas where other people
unconnected with the laser work might be present.
• Be careful of the path of the laser beam. Make the laser path as short as
possible and be sure to terminate the laser path with a diffusion
reflector or diffusion absorber with proper reflectance and thermal
characteristics so that the laser beam does not diffuse. (It is recommended that you install a protective enclosure.)
• Install the laser product carefully so that the laser beam is not unintentionally directed at mirror-like surfaces.
• Install the products so that the path of the laser beam is not as the same
height as that of human eye.
• Wear protective eye goggles appropriate for the laser beam wavelength.
• Do not disassemble this product. Laser emission from this product is
not automatically stopped when it is disassembled.
• Clean the aperture regularly. In addition, stop the emission of the laser
beam when cleaning.
Class 1 Laser Product
WARNING
Follow the instructions mentioned in this manual. Otherwise, injury to the
human body (eyes and skin) may result.
• Do not stare into the beam.
• Do not disassemble this product. Laser emission from this
4
product is not automatically stopped when it is disassembled.
5. Safety features provided with the LB-70
series.
The LB-70 series is provided with the following safety features. Make
sure these features function correctly before operating.
1. Laser radiation emission warning
A visible LED informs you that the laser beam is being emitted, or is
about to be emitted, at least 3 second after power is provided to the
controller and the sensor head.
2. Laser emission delay
Laser emission only starts after the LED has been ON for at least 3
seconds, thus decreasing the possibility of laser exposure.
3. Laser emission stop input terminals
Terminals for controlling laser emission are provided on the controller.
You can remotely control laser emission using these terminals.
4. Key-operated switch
Set to the ON position to supply power. You can lock the power
switch using the supplied key; the key can be removed only when the
switch is set to the OFF position.
5. Beam attenuator
A laser beam shield is supplied. This cover is to be attached to the
laser-beam-emitting portion of the sensor head. If an operator must
work in front of the sensor head and there is risk to the eyes from the
laser beam, be sure to attach this cover.

140 mm [LB-11(W)/70(W)] or 30 to 50 mm [LB-12(W)/72(W)] from the
target. Be sure that the laser-emitting portion of the sensor head is
parallel to the target. When the target is within the measuring range,
the STABILITY LED indicator lights yellow. When the target is at the
center of the measuring range, approximately 100 mm [LB-11(W)/

TROUBLESHOOTING
When abnormal operation occurs, first check following, Trouble-shooting points. If abnormal operation continues after taking the steps outlined below,
Please contact out nearest distributor or the Overseas Division of Keyence Corporation.
Troubles
The monitor voltage
does not change.
The resolution is
not high enough
The monitor voltage
fluctuates.
The monitor voltage
changes drastically
when tow sensor heads
are used, e.g. When
measuring thickness.
Item to be checked
Is the sensor head installed in the correct position?
Is the connector of the sensor head tightened firmly?
Does the STABILITY LED indicator turn red?
Is the voltage in proportion to the displacement out put?
Is the response speed selector switch set to 0.7 ms?/
0.15 ms?
Is the sensor affected by external disturbance light?
Is the main power voltage at the correct level?
Are the lenses of the sensor head clean?
Is the sensor affected by nose?
Is there any vibration on the feeder line?
Is the main power voltage at the correct level?
Does any electric potential reside on the sensor head
mounting surface?
In the span range of only sensor adjusted?
Countermeasures
Install the sensor head in the range where the
STABILITY LED indicator turns yellow or green.
Firmly attach the connector by completely turning the
fastening ring.
Adjust the position and angle of the sensor until the
STABILITY LED indicator turn yellow or green.
Adjust the output voltage using the SPAN dial.
Set the response speed selector switch to SLOW
when fast response is not required.
Take countermeasures against external disturbance
light so that it does not fall on the lenses of the
sensor.
Use a stabilized power supply so that the power
voltage stays within the allowable range
Wipe off dirt or dust with a soft cloth.
Route the wiring of the sensor away from power
cables and high-tension cables.
Reduce vibration near the measurement point as
much as possible.
Use a stabilized power supply so that the power
voltage stays within the allowable range.
Install insulation between the mounting surface and
sensor head.
Adjust the span range of both sensors.

HINTS ON CORRECT USE
CAUTION
Sensor mounting
• When a target consists of differently colored portions or different
materials separated by a border, measurement error may result
depending on the orientation the sensor head. To minimize measurement deviation, install the sensor head parallel to the border line as
shown in the illustration below.
Be sure to use a "W" type controller in combination with a "W" type
sensor head. If you connect a non "W" type controller to a "W" type
sensor head, it may cause an electric shock or may burnout the
controller or the sensor.
Tightly fasten the cable mounting ring
when installing the sensor head.
Avoid turning the cable when
installing or removing the sensor
head; otherwise the cable may be
damaged.
• The sensor head is case-grounded. If noise is generated on the
surface where the sensor head is mounted, it may cause variation in
the analog voltage output, or degradation and breakage of the laser
diode. In this case, install insulation between the mounting surface
and sensor head.
Incorrect Correct
Detectable objects
Mirror surfaced objects may not be detected depending on the direction
in which the light beam is reflected from the target. To correct this,
carefully adjust the angle of the sensor head to the target.
Compatibility
The controller and sensor head are calibrated as pair. Therefore, to
satisfy specifications, combine units having the same serial number.
12
Operating environment
• Keep the sensor head free from water, oil or dust. Any substance that
refracts light or decreases the light quantity may cause measurement
error.
• Do not allow extraneous light to enter the lens of the sensor head.
When highly accurate measurement is required, attach shielding to
the sensor head.
* If extraneous light enters the sensor when no target is present, use
the laser emission control input.
Power supply
All circuit in the sensor head are grounded to the case through a
capacitor. However, noise conveyed through the power supply line may
cause the sensor head to malfunction. Use a stabilized DC power supply
having an insulated transformer. When using a commercially available
switching regulator, be sure to correctly ground the chassis ground or
earth ground terminal.
Warming up operation
Start using the LB series at least 30 minutes after you turn the power
ON. The circuit condition is not stable immediately after the power is
provided, so that the measurement value may vary.
