By configuring a reference point,
moving parts such as doors can
be detected when SE1L is not
correctly positioned, and turns off
the safety output (OSSD). Because
the misalignment of the SE1L can be
detected, hazardous areas can be
avoided, enhancing safety.
When a moving part is set as a reference point, the
output turns OFF when the door is opened.
With the override function, when a
light curtain is interrupted by an object
or when a line stops before muting
conditions are established (when only
one muting sensor is interrupted),
the object interrupting the light does
not have to be removed. Therefore,
the line can be started smoothly and
safely.
Specific areas of the protection zone
can be disabled by the muting sensor.
Complicated protection zones can be
configured easily.

Warning zone 2
Similarly, when an object is detected in a warning zone,
the WARNING signal will turn OFF. The distance is
measured by the Time of Flight (TOF) principle. When
the motor rotates, the pulse laser beam is emitted within
the scanning range of 190º and is reflected back from an
object within the range. The distance can be calculated as
follows:
L =1

2× C × T
L = Distance to the object
C = Speed of light

Scanning Area
The scanning area of the SE1L consists of a protection
zone and two warning zones. A protection zone is an
area that is directly connected to an OSSD signal. When
an object is detected in the protection zone, the SE1L
switches the OSSD signal to OFF (triggers the switch that
stops the machine or the AGV). For moving applications,
the OSSD signal is used as an emergency stop signal.
Protection Zone
Below are examples of protection zones configured by
manual mode and auto mode with the SLS Configurator.
The operator must configure the software so that the
hazardous areas are fully protected.

SE1L Safety Laser Scanner
Warning Zone
The warning zone is a non-safety area and is connected to
WARNING 1 and 2 outputs.
When an object is detected within this zone, the WARNING
signal turns from ON to OFF. The warning signal can
be used as an alert signal to prevent humans or objects
approaching the protection zone. For moving applications,
warning zones can be used to reduce the speed of the
AGV to avoid collision.
Warning Zone 1
Warning Zone 2
OSSD
The OSSD signal is a safety signal. When humans are
detected inside the protection zone, the OSSD signal turns
from ON to OFF. Also the OSSD signal has a self-diagnosis
function that tests the signal periodically to detect
malfunction. The OSSD signal will turn OFF when a error is
detected due to the self-diagnosis function.
xThe OSSD is a safety signal and should be
connected directly to a force guided relay or a
device that controls the machine or AGV.
xWhen setting the response time of the OSSD
signal, provide sufficient time to stop operation
of the machine or AGV.
xThe operator must test to make sure the settings
are properly configured before operation.
Note: The signal is 24V when the OSSD signal is ON and 0V when OFF.
Self-Diagnosis Function of the OSSD
The self-diagnosis function of the OSSD detects
abnormality by switching OSSD 1 to OSSD 2 at intervals
of 300 µs maximum. Therefore, a safety relay or converter
must not respond to this self-diagnosis function.

OSSD Signal and Condition of SE1L
The OSSD signal will switch to OFF (0V) when an object
enters a protection zone or when a error is detected by the
self-diagnosis function. By observing the READY signal
and ERR signal with OSSD signal, the operator is able to
recognize the condition of the SE1L. Below shows the
start-up status and operating status between the OSSD,
READY, and ERR signals.

Area Switching
The SE1L can store up to 16 area patterns. Each area
consists of a protection zone, warning zone 1, and
warning zone 2. To switch areas, an external input signal
is required. Table below shows the combinations of input
signals for switching areas.
The number of the current area is displayed on the
7-segment display of the SE1L. The switching time of
areas can be configured.

Lockout
When an error is detected by the self-diagnosis function
normal operation cannot be performed, and SE1L will
change to a lockout state. In this condition, the OSSD1, 2
and WARNING 1, 2 signals turn OFF. Only when the cause
of the error is removed and the power is reset, the lockout
state can be cleared.

OSSD Interlock
Interlock is a function to prevent the OSSD signal restarting
automatically from OFF to ON. The following functions can
be set using the SLS Configurator.
Automatic restart
When the interlock function is disabled or restart interlock
is set to automatic mode, the SE1L will operate in
automatic restart mode. When the objects in the protection
zone are removed, the OSSD signal will automatically turn
from OFF to ON.
In the figure below, “a” is the OFF delay and “b” is the ON
delay. However, if the OSSD signal changes due to lockout
of the sensor, the OSSD signal will remain OFF even when
the interlock function is disabled.

Note:
xWhen using automatic restart, because the OSSD automatically turns ON
when the object is removed, take appropriate safety precautions.
xWhen using the delay function, make sure that the delay time is sufficient
to stop the machine or AGV.
Manual Restart
When the restart interlock is set to manual, the OSSD
signal will remain OFF even when the object in the
protection zone is removed or when an error is cleared. For
the SE1L to return to normal operation, an external reset
input signal is required to clear the interlock. The SE1L
will resume normal operation when there is a reset signal.
The time for the reset signal should be 0.5s minimum.
When the reset delay is set to “c” as shown in the figure
below, the OSSD signal will turn ON when the OSSD signal
reaches the delay time. However, if the OSSD signal turns
OFF due to internal failure, the OSSD signal remains OFF
regardless of the set delay time. The reset delay can be set
from 1 second to 6 seconds.

The configuration for start interlock can only be configured
manually. This function is used to maintain the OSSD in an
OFF state until the external reset signal is input at start-up.
The RES_REQ signal turns ON after start-up preparation
and ready to receive the reset signal. When the reset signal
is input, if there is no object in the protection zone, the
OSSD signal will turn ON. The input time of the reset signal
must be more than 0.5 seconds.

Muting Function
Muting function is a function to temporarily stop the safety
function in the protection zone. During muting, the OSSD
signal will remain ON even when an object is detected
in the muting area. The muting function can be started
and stopped using two signals that are independently
wired. Muting areas can be configured using the SLS
Configurator. When the muting input satisfies the starting
conditions, the SE1L stops the safety function within 60
ms. (For details, see the user’s manual)

consideration the guidelines mentioned below.
1) The hazard must be identied before performing a risk
assessment.
2) Do not use the SE1L for nger protection.
3) Use under an operating environment within the
specications of the SE1L.
4) The safety distance must be determined in accordance
to ISO 13855 and IEC 61496-3.
xUsing sensors that exceed specifications may
lead to critical injury or death.
Hazardous Area Protection (Stationary)
In this application, the SE1L is horizontally installed to
protect the hazardous area. The protection zone is set
around the hazardous area to prevent humans or objects
from entering the hazardous area. Warning zones 1
and 2 are configured to surround the protection zone.
The warning zones prevent the machine from stopping
unnecessarily and can be used as a warning to humans or
objects that approach the protection zone. By detecting
humans or objects in the protection zone, the OSSD signal
switches from ON to OFF. Also, when humans or objects
are detected in the warning zone, the warning zone output
(WARNING signal) switches from ON to OFF.

Response Time
The response time for the OSSD signal can be configured
by the SLS Configurator. The response time for WARNING
1, 2 is the same as the response time for OSSD. The
stability of the SE1L can be increased by setting a long
response time, but a long safety distance is required. (See
Calculating the Safety Distance on page 13 to 15.) Before
setting the response time, the user must perform a risk
assessment. The configurable response time is shown in
the table below. Be sure to add the time taken to switch
areas (30 ms)

Other Outputs
SE1L has 3 non-safety outputs such as WARNING1,
WARNING2/ERR/MUT_OUT, and READY/RES_REQ.
WARNING2/ERR/MUT_OUT (WARNING2 at default) and
READY/RES_REQ (READY at default) use the same
output terminal and can be configured using the SLS
Configurator.
Warning Output (WARNING1)
This signal turns OFF when an object is detected in
protection area 1.
Warning Output (WARNING 2)
This signal turns OFF when an object is detected in
protection area 2.
Error Output (ERR)
ERR output shows the operating status of the SE1L. This
signal turns OFF when an error is detected by the self-
diagnosis function of the SE1L.
Muting Output (MUT_OUT)
MUT_OUT indicates the MUTING/OVERRIDE status of the
SE1L. When muting is activated, MUT_OUT turns ON. In
a muting status, the 7-segment display shows “18”. In an
override status, the display shows “19”. Use this signal to
indicate whether the SE1L is in a muting status.
Ready Output (READY)
This signal turns ON when the SE1L is ready for operation.
Reset Request (RES_REQ)
This signal turns ON when the SE1L is ready to receive the
reset signal.

Zs = Additional safety distance of SE1L (mm)
xInstall the SE1L so that the distance between the
end of the hazardous area and the origin of the
protection zone “a” is shorter than the minimum
sensing width. If the distance of “a” is longer
than the minimum sensing width, additional
protection measures must be taken so that
objects cannot enter the unprotected area.
xDo not install the SE1L higher than 300 mm
to prevent obstacles entering beneath the
sensing plane. If there is a need to install the
SE1L higher than 300 mm, take measures to
prevent obstacles entering beneath the detecting
surface.
xTo install the SE1L in a public area, make sure
that the height from the floor to the sensing plane
is within 200 mm or install according to local
height regulations.
xTo use the SE1L for presence detection (when
an object enters the protection area horizontally),
make sure to set the minimum sensing width to
less than 70 mm.
Note:
xIt is recommend that markings are placed on the floor so that the
protection zone is clearly defined.
xTo configure the safety distance, the additional safety distance must be
taken into consideration.
xWhen operating the SE1L in a high reflective background environment,
additional distance must be added.
xMake sure that protective measures or background are not detected in the
protection zone. If they are detected as an object, the OSSD remains OFF.
Hazardous Area Protection (Movable)
The SE1L can be used for movable applications. In an
application using an AGV, the SE1L on the AGV detects
humans or objects while traveling on the fixed route.
The warning zone signal is used to slow down the AGV
and the OSSD signal can be used to stop the AGV when
required. By using the area switching function of the SE1L,
the AGV can use 16 different area patterns based on its
traveling route. When using the SE1L on an AGV, take
into consideration the time needed for the AGV to stop
completely when configuring protection zones and warning
zones.

Access Detection (Detecting the Entire Body)
When constructing a protective shield, the SE1L can be
installed vertically. In the application below, it is used to
prevent access into hazardous areas. When an object
or human enters the hazardous area, the OSSD signal
switches from ON to OFF. When the SE1L is installed
vertically, an object or human is detected by the vertical
sensing plane. The front and rear of the sensing plane
cannot detect objects or humans. Therefore, the distance
between the approach and hazardous area must be
carefully determined. The reference monitor function must
be used for this kind of application. If a displacement
occurs within the reference background, the OSSD signal
turns OFF.

than the minimum sensing width, additional
protection measures must be taken so that
objects cannot enter the unprotected area.
xFor access detection applications, if the
approach angle exceeds ±30º be sure to use the
“reference monitor function” The response time
must be 90 ms maximum for access detection
applications. Set the tolerance range of the
reference area to 100 mm.
xIn order to detect displacement, make sure to set
a reference area on each side.
xMake sure that the SE1L is installed in a way that
access to hazardous points is impossible. Take
additional protection measures if necessary.
xBefore setting the reference area, take into
consideration the tolerance range.
Note: When setting the minimum sensing width to 30 mm,
the value C can be replaced by 0.
Access Detection (Detecting Parts of a Body)
When constructing a protective shield, the SE1L can be
installed vertically. It is used to prevent a part of a body
from reaching a hazardous area. When an object or a part
of a body enters the hazardous area, the OSSD signal
switches from ON to OFF. When the SE1L is installed
vertically, the vertical side of the object or human is
detected. The front and rear of the sensing plane cannot
detect objects or humans. Therefore, the distance between
the approach and hazardous area must be carefully
determined. The width of the protection zone must be
configured to fully cover the hazardous area. The reference
monitor function must be used for this kind of application.
If a displacement occurs with the reference background,
the OSSD signal turns OFF. For details, see the user’s
manual.

Installation
Light Interference
SE1L is a sensor that transmits pulsed laser for obstacle
detection. Interfering light sources may lead to false
detection. Before using the SE1L, examine the surrounding
environment. Be sure to avoid the following light sources.
1) Incandescent light
2) Florescent light
3) Strobe light
4) Flashing beacon
5) Sunlight
6) Infrared light source
However, if the SE1L must be used under the above
environment, install the SE1L so that the light source is
located more than ±5 degrees from the sensing plane to
prevent light interference.

xFor details on the wire colors and function, see page 17.
xTo examine the object detecting performance, use a
test piece the size equivalent to the minimum detectable
object.
xError occurs when detection capability is below 30% due
to homogenous dirt on the optical window. The operator
must keep the windows clean
xWhile SE1L is removed, a protective measure must
be taken to ensure safety within the protection zone.
To prevent entry into the danger zone, use protective
materials such as a safety guard or light curtain.
xDispose the SE1L as industrial waste or in accordance
with the local regulations.
xDo not perform withstand voltage tests or insulation
resistance tests. Varistors that are used in power circuits
may be damaged.
Operating Environment
xMake sure that the operating environment is within
the range of the specifications (temperature, humidity,
vibration, light interference).
xDo not use the SE1L near a machine that may generate
strong radio waves. It may interfere with the operation of
the SE1L.
xDo not use or install the SE1L where dust, smoke, or
corrosive chemical substances exist. Using the SE1L
under these environments may lead to degradation of
detection performance.
xWhen the interlock function is active, make sure that the
surrounding environment, especially within the protection
zone, is safe before resetting the interlock.
Safety Precautions
For correct use of the SE1L, take note of the following
precautions.
xSE1L is a AOPDDR (Active Optoelectronic Protective
Device responsive to Diffuse Reflection) that detects
diffused emitted light within the protection zone. The
emitted light is irradiated within the protection zone by
the rotating motor and reflects back from the objects as
diffused reflective light and is detected by the receiving
unit of the SE1L.
xPerform tests before operation to check the function and
performance of the SE1L.
xUse the SE1L within the specification range described
in the manual. To prevent degradation of detection
characteristics, make sure that maintenance is carried
out.
xTo maintain the degree of protection, do not modify or
disassemble the SE1L.
xThe operator must be a person qualified to operate
the SE1L. The operator must be trained and be able to
operate the SE1L correctly.
xThe administrator must provide continuous training to the
operator for correct use of the SE1L.
xWhen using the SE1L in a safety-related system, the
administrator must be responsible for following safety
requirements, standards, rules, regulations, and laws of
each country, state, or district.
xThe administrator must understand the manual and be
responsible for ensuring appropriate operating conditions
for SE1L.

Safety Precautions
Installation
xInstall the SE1L on a stable surface or structure to
prevent displacement of the sensor.
xInstall the SE1L securely so that screws do not loosen
due to shock or vibration. (Recommended tightening
torque 3N∙m). Displacement may degrade protection
performance.
xDetermine the safety distance before installing the SE1L.
After installing the SE1L, use a test piece for all protection
zones to check the sensing functions. (Calculating safety
distance : see page 13)
xAfter installing the SE1L, to prevent entry into the
protective zone, use protective materials such as safety
guards and light curtains.
xThe reset switch to reset the interlock function should be
installed far from the protection zone.
xIf several SE1Ls are installed on the same sensing plane,
mutual interference may occur. For countermeasures on
mutual interference, see page 16.
xProvide enough space for installation and maintenance of
the SE1L.
xDo not cover the front of the optical window with glass or
transparent cover, otherwise detection characteristics of
the SE1L may be impaired.
xSE1L will not operate without initial configuration.
xMinimum sensing width differs according to the distance.
For details on performance specifications see page 6.
xThe stability of the SE1L increases by delaying the
response time of the OSSD signal but the sensing
performance decreases for moving objects. Before using
this function, be sure to carry out risk assessment.
Wiring
xBe sure to turn off all the power before wiring.
xWhen using converter power, make sure to use power
that satisfy the following requirements.
1) The rated output voltage is within 24V DC±10% (SELV
circuit, overvoltage category II)
2) The circuit between primary circuit and secondary
circuit is reinforced insulation or double insulation.
3) The output holding time is 20 ms.
4) The power supply must comply with electrical safety
and electromagnetic compatibility (EMC) regulations
requirements of each country, state, and district.
xAll input/output cables must be located away from power
cables and high voltage cables.
xTo control safety-related machine or system, use OSSD
output. Because warning zone output (warning signal) is a
non-safety signal, do not use for safety purposes.
xOnly use cables made for the SE1L. (For details see page
17.)
xUse an exclusive cable for connecting OSSD output wire
cable and safety-related machine or system.
Installation
xA password is used for configuring the safety function.
Only an administrator or operator should be able to use
the password.
xPerform test operation and check the configuration
before using the SE1L.
xThe operator must record the changes made in the
configuration. SLS Configurator report function is
available. For details, see the user’s manual.
Testing and Maintenance
xThe operator should perform the following tests or
maintenance based on the checklist.
1) Pre-operation inspection
2) Operation inspection
3) Daily inspection
4) Periodic inspection
This checklist is a basic guideline for performing
tests and maintenance. The operator should perform
additional tests and maintenance if necessary.
xStop the machine if failure occurs during tests.
xClean the optical window if any dirt is found, ask for
repair if damaged.
xDo not drop the SE1L. Otherwise damage or
failure may occur and performance cannot be
guaranteed. Also, injury may occur.
xSE1L cannot be sold, imported, or used in the Federal
Republic of Germany until December 2013.
