SCANNING AREA
The IEC/DIN Warning labels are packed with the scanning head. Stick the Warning
labels on the scanning head or the vicinity where the scanning head is mounted in
order to be easily seen by the operators.
1.4 Safety Consideration
Use of controls or adjustments or the performance of procedures other than those
specified herein may result in hazardous radiation exposure.
The LS-5041 employ a visible semiconductor laser for its light source. The beam is
not harmful to the skin. The possible health hazard is in exposing the eyes to the
laser beam. Damage to the eyes occur if the operator stares directly into the beam.

Chapter 1 Laser Safety Precautions
WARNING
1
Follow the safety precautions below to ensure operator safety:
• Operate the LS-5000 series only according to the procedures described in
this instruction manual.
Otherwise, injury may occur due to exposure to the laser beam.
• Do not disassemble the scanning head.
Laser emission from the LS-5000 series is not automatically stopped if the
scanning head is disassembled. If you disassemble the scanning head for
inspection or repair, you may be exposed to the laser beam. If the LS-5000
series malfunctions, contact KEYENCE immediately.
• Do not look directly into the laser beam.
Looking directly into the laser beam may result in serious eye injury.
• Protective enclosure
We recommend that you install a protective enclosure around the scanning
head to prevent any person from getting near the scanning head during operation.
• Protective goggles
We recommend that you wear protective goggles when using the LS-5000
series.
• You must stop all laser emissions before cleaning the laser aperture. Otherwise,
you may be exposed to the laser beam.
• Be aware of the optical axis of the laser beam.
If you may be exposed to a specularly-reflected or diffused laser beam, provide
an enclosure with reflectivity and thermal characteristics adequate to interrupt
the laser beam.
Install the LS-5041 so that the optical axis of the laser beam will not be at the
same height as your eyes when operating the LS-5000 series.
1.5 Safety Features Provided with the LS-5000 Series

• LASER ON alarm indicator
The scanning head has an LED which indicates that the laser beam is currently
being emitted or is about to start.
Even when you are wearing safety goggles, you can check whether the indicator is
lit or not.
Laser ON alarm indicator
• Laser beam shield
The LS-5000 series includes a laser beam shield which is to be attached to the
scanning head’s transmitter. Attach this shield when your eyes may be exposed to
the laser beam, for example during operation at the front of the scanning head.

CAUTION
1.6 Preparation for Operation
■ Suppressing noise interference
Be sure to isolate the connection cable from high-voltage or power lines. If the
connection cable is placed in the same conduit as these lines, the LS-5000 series
may malfunction due to noise interference.
■ Cooling fan
Do not block the cooling fan at the bottom of the LS-5501. If the cooling fan is
blocked, the LS-5501 may overheat and malfunction.
■ Operating environments
• Use the controller at an ambient temperature of 0°C to 45°C (32 to 113°F), No
freezing.
• Fluctuations in the ambient temperature cause measurement errors; therefore,
the ambient temperature should be kept constant. If the temperature changes
by 10°C (18°F), the LS-5000 series will take approximately 60 minutes until the
temperature distribution in the unit becomes even.
• Do not allow any substance which may refract the laser beam, such as water
and oil, to adhere to the scanning head.
* Blow dust off the protective glass using clean air. Wipe off any remaining dust
using a soft cloth moistened with alcohol.
Note 1: Measurement conditions
When the target oscillates, the measured value may fluctuate. The measurement
accuracy can be improved when the number of averaging measurements is set
higher.
Note 2: Target
When the target shape or luster varies, a measurement error may occur. In this
case, place a standard target in the measuring area and perform the calibration
using the [CALIB] key.

This section describes the procedures for starting measurement for trial operation.
3.1.1 Procedure for Starting Measurement
3
Connect the controller and scanning head.
▲
Turn the power on.
▲
Align the optical axis of the transmitter and
receiver.
▲
The 5001 series starts laser emission in
approximately 5 seconds, at which time the
measurement begins.
▲
Place a target in the measuring area.
▲
The measured value is soon displayed.
For information on the connection
procedure, see p. 8.
• When the transmitter and receiver are
fixed to the scanning head mounting
frame, optical axis alignment is not
necessary.
• For information on the scanning head
mounting allowance, see p. 18.
For information on checking the optical
axis, see p. 60 and 61.
For information on the measuring area,
see p. 115.
The factory setting for the number of
averaging measurements is 768 for DIA
mode.
Before changing the measuring mode or the number of averaging measurements,
read this instruction manual thoroughly for the correct settings.
For setting items, see the table of contents.

4.1 Mounting the Scanning Head
The LS-5000 series comes with the transmitter and receiver fixed to the scanning
head mounting frame. To use the LS-5000 series with the transmitter and receiver
removed from the mounting frame, mount the scanning head so that the following
specifications are met. This will eliminate measurement errors caused by optical
axis misalignment.
Allowance for Mounting the Scanning Head
■ Horizontal deviation of transmitter and receiver positions
4
■ Inclination of transmitter and receiver
* Values in parentheses are for the LS-5121.

This width can be
measured when
SEG(m,n) is set to (0,2) in
Normal mode.
5.1 Area/Segment/Edge
When a target is placed in the measuring area, there are areas where the laser
beam is received (laser beam enters the receiver), and where the laser beam is
interrupted by the target (shadow of the target is projected on the receiver). The
border between the light and dark areas is called “EDGE”. Each section divided by
the edge is called a “SEGMENT”. The measurement "AREA" is determined by two
edges and includes all "SEGMENTS" between these two edges.
* The edge number is counted in the laser scanning direction starting at T.EDGE
(top edge).
5
5.2 Normal Mode
Note: EDGE 0
The position of the photodiode for synchronization is called “EDGE 0”.
EDGE 0 can be used as a reference point during roller oscillation measurement or
sheet edge control. (No reference edge is required.)
Example: Roller oscillation measurement
➮
For the setting procedure, see p. 39.
The LS-5000 series has two measuring modes; NORMAL and PITCH. NORMAL
mode provides four types of measurement3: “DIA”, “T.EDGE (Top Edge)”,
“B.EDGE (Bottom Edge)” and “SEG(m,n)”.
The function of each mode is described below. Select the mode that suits your
measurement condition.

Example: Outer diameter measurement using a rod or transparent object
The width between the lower edge of the first light segment and the top edge of the
last light segment is measured.
• When one target is measured
• When several targets are measured
5.2.2 T.EDGE (TOP EDGE) Mode / B.EDGE (BOTTOM EDGE) Mode
Example: Measurement of a gap between rollers
T.EDGE: Measures the width of the first light segment.
B.EDGE: Measures the width of the last light segment.
5.2.3 SEG (m,n) Mode
Example: Inner diameter measurement using a bearing
When two edges are specified, the width between these edges is measured.
5
* (m,n) indicates any number between 0 and 254. “m” should be smaller than “n”.
Note: DIA mode
Since DIA mode is basically intended for outer diameter measurement of a rod,
transparent tube or other round surface, the measurement error due to the round
surface is calibrated.
To perform outer diameter measurement of a round target, select DIA mode.
