Notice for safety
Special markings and symbols are used in this document to alert the
reader especially to safety-related issues. Follow strictly the instructions
marked by these special markings and symbols to ensure safety during
the operation.
Mark Meaning
Danger Procedures that could lead to dangerous situation, critical injury ordeath if not carried out properly.
Refer SE2L user's manual for details.
Read section 12 "Instruction for using SE2L for the first time
afterpurchase" when using the device for the first time.
1. Safety precautions
Danger
Please read the following guidelines for correct use of the SE2L. Proper
handling and usage ensure the SE2L to operate accordingly.
(1) General
Danger
● SE2L is an AOPDDR that detects obstacles within the configured
protection zone by detecting diffused optical radiation. Optical
radiations are generated and emitted into the configured protection
zone. The optical radiations are then rotated by a rotating motor
covering the protection zone. The optical radiations are diffused
and reflected back towards the receiving unit of the SE2L.
● SE2L is designed to protect human begins or systems by
monitoring the hazardous area. It is not designed for the protection
from high speed objects or the electro magnetic radiation.
● Pre-operation tests must be performed in order to verify the
functionality and the performance of the SE2L.
● Do not modify or disassemble SE2L. Such modifications will affect
the detection capability leading to injuries or death.
● Do not modify or disassemble SE2L to maintain its housing rating.
Such modifications will void the warranty.
● Operator is referred to a person who is responsible and qualified
to operate the SE2L. Operator should have attended appropriate
safety-related training and could operate the SE2L correctly.
● A person-in-charge must be assigned and have trained the
operator about the correct use of SE2L.
● The person-in-charge is responsible to ensure the proper working
environment for SE2L.
● The person-in-charge is responsible for the compliance with the
local safety requirements, standards, rules and regulations, laws
of respective nations, states or districts when the SE2L is used in a
safety-related system.
● SE2L has been manufactured and shipped under the strict quality
control. If you find any defect in the product contact the nearest
distributor or sales representative.
● IDEC cannot be held responsible for the damages or failure due
to misuse of the product by customers or third parties. IDEC
cannot take responsibilities for any loss from the misuse except for
the responsibilities govened by low.
● User should prepare test pieces for detection capability verification.
The test piece should emulate the smallest object that is intended
to be detected during the operation.
● Maximum level of homogeneous pollution for SE2L is 30%.
Warning signal will be displayed if the pollution exceeded the
stated limit. However, operator should always keep the optical
window in clean condition.
● Before resetting the interlock of the SE2L, operator must ensure
the surrounding is safe especially in the protection zone.
● During decommission of the SE2L, protective measures must be
taken to ensure safety on the protection zone. Protective materials
such as guards or light curtain should be used to prevent any
passage into the hazardous area.
● SE2L including its accessories are subject to change without prior
notice for the improvement.
● SE2L should be disposed as industrial waste or in accordance with
the local disposal directives.
(2) Operating environment
Danger
● Make sure that SE2L’s operating environment is within the stated
specification (temperature, humidity, ambient light, etc.). Using
SE2L in the out-of-spec environment may cause malfunction or
decrease the detection capacity.
● Do not use or mount SE2L near devices that could generate strong
electromagnetic waves as it could affect the operation of SE2L.
● Do not use or mount SE2L in dusty, smoky, or misty environments,
or where corrosive substances are present. Operating under such
environments may decrease the detection capacity of SE2L.
● This product is for indoor use only.
(3) Installation
Danger
● Install the SE2L on a firm surface or structures to avoid
displacement of the sensor.
● The SE2L should be firmly mounted using screws. Shock and
vibration should not loosen the mounting. SE2L will not operate
properly if the protection zone is different from the intended area
due to the displacement. Recommended torque for screws is 3 N・m.
● Safety distance must be determined before installing SE2L. User
must ensure the functionality of the SE2L after installation by
placing a test piece in all the protection zone.
● During the installation of the SE2L, protective materials such as
guards or light curtain should be used to prevent any passage into
the hazardous area.
● Reset switch used for interlock, muting and override function should
be mounted at a location away from the protection zone. Also the
whole protection zone must be visible from the switch location.
● Mutual interference could occur when identical SE2Ls are mounted
at the same detection plane.
● SE2L should be mounted at a location which has sufficient space
for maintenance.
● Do not add any protective materials such as glass, transparent
cover etc in front of the optical window. This would lead to loss of
detection capability of the SE2L.
● Minimum detectable width varies with the distance.
(4) Wiring
Danger
● Switch OFF all the power supply during wiring.
● If the source of the power supply is taken from a converter, please
ensure the power supply fulfills the following requirements:
a) A rated output voltage of 24VDC ±10%(SELV circuit,
Overvoltage Category II)
b) Reinforced insulation or double insulation for the primary and
secondary circuit
c) Holding time of the output should be above 20ms
d) The power supply must comply with the requirements of
electrical safety and electromagnetic compatibility (EMC)
regulations of the respective country, states and district.
● All the input/output signal cables should be installed away from
machines power lines and high-voltage cables.
● Use OSSD of the SE2L to control safety-related machine/system.
Do not use Warning signals to control safety-related machine as
these are non-safety signals.
● Both the OSSD1 and OSSD2 outputs should be connected to the
safety-related machines or control system. If OSSD3 and OSSD4
are used they must be connected in the same manner.
● Use shield cable for the connection between OSSD signals and
safety-related machines or systems.
(5) Configuration
Danger
● Configuration of safety functions are password protected. Only
authorized personnel or operator with password are allowed for
configuration.
● SE2L will not operate without an initial configuration.
● Pre-operation test must be performed to verify the configurations
before operating the SE2L.
● Increasing the response time of OSSD will increase the stability of
SE2L. However, this will reduce the detection capability towards
moving objects. User must perform risk assessment before using
this function.
● Changes made during the configuration must be recorded.
Operator can use the report generating function in the S E2L
Project Designer.
(6) Test and maintenance
Danger
● User must perform the following tests and maintenance by
referring to the checklists in this manual.
a) Pre-operation inspection
b) Operation inspection
c) Daily inspection
d) Periodical inspection
*The checklists in this document are provided as basic guidelines
while performing the test and maintenance. User must perform
additional inspection and maintenance tasks deemed necessary
for the respective application.
● Stop the machine and stop using the SE2L if faults are detected
during these tests.
● Clean the optical window when it gets contaminated. If the optical
window is damaged it should be replaced by a new one.

5.Functions
SE2L's function can be configure using the SLS Project Designer.
(1)Scanning area
Scanning area of SE2L consists of protection zone and warning
zones. Maximum 32 sets of area can be configured. Further, two
combinations for protection and warning zones can be selected for
the operation.
a) Protection zone, Warning zone 1 and
Warning zone 2
b) 2 Protection zones (Dual Protection)
In dual protection mode, two protection
areas can be configured therefore two
mchines can be protected by one unit
of S E2L .Protection and warning zones
can be configured by using SLS Project
Designer.
● Protection zone
Protection zone is safety-critical and directly connected to the OSSD
signal. When an obstacle is detected in the protection zone, SE2L
will switch the OSSD from ON-state to OFF-state (which should
trigger a switch to stop a machine or AGV). For mobile applications,
the OSSD signal can be used as the emergency stop signal. Figure
1 shows the examples of protection zone configured using manual
mode and teaching mode respectively. User must configure these
zones accordingly to ensure hazardous area is completely protected.
● Warning zone
Warning zones are non-safety zones and are connected to Warning1 and
Warning2 outputs. When the obstacle is detected in the warning zones, SE2L
will switch the respective warning signal from ON-state to OFF-state.
Warning signals can be used as an alert signal to avoid human beings or
objects from approaching near the protection zone. For mobile applications,
warning signals can be used for reducing the speed of automatic guided
vehicle (AGV) to avoid collision.
(2)OSSD
OSSD is safety-related signal. When humans or objects are detected
in the protection zone, the OSSD signal will switch to OFF state from
ON-state. OSSD signal has the self- diagnostic function which tests
the signal periodically. Signal is continuously switched to OFF-state
when an error is detected during the diagnostic.
Output states of OSSD1 and OSSD2 signal are identical. Both
signals should be connected to the safety related machines or
control system to fulfill the required safety level. If OSSD3 and
OSSD4 are used they must be connected in the same manner.
(3)Interlock function
Interlock is a function to prevent automatic restart of the OSSD
signal switching from OFF-state to ON-state. OSSD1/2,RES_REQ1
and RESET1 are for protection zone 1; OSSD3/4,RES_REQ2 and
RESET2 are for protection zone 2 when setting the sensor by SLS
Project Designer. We use OSSD, RES_REQ and RESET in the rest
of this document as representative terms.
● Automatic restart
SE2L will restart automatically when interlock function is disabled or
the restart interlock function is set "auto" when interlock is enabled.
When obstacle from the protection zone is removed, OSSD signals
switch from OFF-state to ON-state automatically.
However, if S E2L is in the lockout state due to error, OSSDs will
remain in OFF-state even if the interlock function is disabled.
● Manual restart
When interlock function is set to manual restart mode, even if the
detected obstacles or system error is removed, OSSD signals will
remain in OFF-state. An external reset input signal is required to
release the interlock which allows the SE2L to switch to normal
operation. RES_REQ signal will be switched to ON state when
obstacles disappear from protection zone. SE2L will resume normal
operation only after confirming the reset signal (RESET). The
duration of the reset signal should be more than 500ms. After RES_
REQ signal becomes ON and reset signal is confirmed, the OSSD
signal will switch to ON-state after the lapse of the configured delay
time. If OSSD's OFF-state is due to an internal fault, it will remain
in OFF-state even when reset signal is provided. Reset delay is
configurable in the range of 1s to 6s.
● Manual start
Start interlock is a function which keeps the OSSD in OFF-state
during the start-up until an external reset input is applied. Start
interlock setting has only manual mode. The RES_REQ signal
switches to ON-state after the SE2L completes initial routines and
ready to accept the RESET input. When RESET input is applied,
OSSD will switch to ON state if no object is detected in the protection
zone. The duration of the reset input should be more than 500ms.
Delay can be configured in the range of 1s to 6s.
(4)External device monitoring (EDM) function
EDM is a function that monitors the state of the input signal from
the controlled machine or automated guided vehicle (AGV). EDM
is configured using the SLS project designer. When EDM function
is enabled, any fault detected in EDM signal will switch the OSSD
signal to OFF-state. Logic of EDM signal should be always inverse of
the OSSD signal. EDM input signal ON/OFF delay is configurable to
match the user’s system. Please do not connect EDM input when
this function is not needed.
(5)Muting function
Muting function temporarily suspends the safety function in the
configured zone of SE2L when the specified conditions are fulfilled. In
the muting state OSSD remains in the ON-state even when an object
is detected in the configured muting zone. Two independent hard
wired input signals are provided to start and end the muting function.
Muting zone is configured using the SLS project designer. When
muting inputs fulfill the muting start conditions, SE2L will suspend the
safety function for the muting zone within 60ms.
● Muting start condition
Muting function will start when the following conditions are fulfilled:
a) There are no objects in the protection zone and the OSSD is in
ON-state.
b) The two independent hard wired muting input signals are switched
to ON state in the predefined sequence within the pre-set time
interval. However, the switching interval between two input signals
should not be 0.
● Muting stop condition
Muting function will stop when any one of the condition below is
fulfilled:
a) One of the muting inputs switches to OFF-state.
b) When the muting state exceeds the predefined maximum muting
time.
c) Objects are detected in the protection zone which is not covered
by the muting zone.
d) Error is detected by the self-diagnostics function.
e) During muting state when the area is switched to another area.
● Muting override function
Muting override is a function to recover SE2L when the OSSD is
switched to OFF state due to muting related errors by temporarily
suspending the safety function. Override function is active when the
override input (OVERRIDE 1/2) and the reset input (RESET1/2) are
switched in a sequence.
(6)Reference monitoring function
Reference monitoring is a function to monitor the displacement of the
SE2L or the structure used as reference boundary.
● Access protection
An example of reference monitor function used for access protection
is shown in figure 1. Reference segments should be configured
on each surface for displacement detection. Reference segments
should be configured such that displacement can be easily detected.
The OSSD will switch to OFF-state when access penetration is
detected, and also if the distance between SE2L and the reference
structure changes. This function is compulsory for vertical
applications.

Fig-2. Front view of the access detection using reference monitor function
※This function can be also used in area protection applications. Refer to User's
Manual for the detail.
(7)Area sequence function
Area sequence is a function to monitor sequences of area switching.
When this function is activated, OSSD signal will switch to OFF-state
if the switching pattern is other than the configured sequence. This
function prevents the machine to operate with random protection
zone.
From each area, switching selection to maximum 31 other areas is
possible when configuring the area sequence. And, it is necessary to
specify 1 or more areas to avoid error.
< Area switching sequence >
When area sequence is disabled, SE2L can switch from an area to
any other areas (Figure 3) whereas it can only switch to specified
areas if area sequence is enabled. (Figure 4).
Area sequence function is recommended for control systems where
switching area sequences can be configured.
Fig-3. Operation without area sequence Fig-4. Operation with area sequence
(8)Response time
Response times of OSSD signal, OFF response time (Default 60ms)
and ON response time (Default 270ms) are configurable individually
for each area using the SE2L project designer. Response time of
the Warning 1 and Warning 2 will be same as the OSSD response
time.Table 1 shows the possible configurable values.In the dual
protection mode, it is possible to set a separate response time for
each protection area.
When longer response time is configured, the stability of SE2L can
be increased. However, longer response time requires longer safety
distance. User must perform risk assessment before configuring the
response time. Addition of maximum 1 cycle(30ms) has to be taken
into account for the area switching.

(9)Area switching
A maximum of 32 sets of area can be configured in SE2L. However
the maximum configurable area number differs depending on the
selected function such as, muting and dual protection. Table 2 shows
the maximum configurable area number according to the used mode.
External input signals are provided in SE2L for switching the area.
Each signal has a pair of normal and inverted signal. For example,
it is necessary to provide both input signal IN_A and inverse IN_
A signal to switch the area. Error will occur if IN_A and inverse IN_
A signals do not complement each other. Table 3-2 below shows
the combination of input signal to switch the area. Area in use will
be displayed in the 7 segment LED of SE2L . It is also possible to
configure area input delay. Configure the necessary delay required
for the system to provide stable input signals to SE2L . The default
value is 30ms.
There are maximum 5 input pairs (a pair is a combination of normal
and inverted signal) in SE2L therefore, it can operate with maximum
32 sets of area. Further, it is also possible to switch the area through
the speed monitoring of increment encoder signal connected to
SE2L.

(10)Increment encoder
In SE2L there are 2 pairs of encoder input terminals for connecting
2 units of dual channel incremental encoder signals. Area will be
switched depending on the encoder speed. Direction of travel
is detected by encoder's phase A and phase B signal that have
the phase difference of 90°. Speed and rotating direction of both
encoders are constantly monitored to detect abnormal travel and
stop the AGV.
(11)Ethernet communication
Measurement data of S E2L can be obtained from the Ethernet
communication. For the communication specification of SE2L, contact
Water proof Ethernet connector is located at the back of SE2L.
To connect sensor with PC use an Optional Ethernet cable
(SE9Z-HS2-XCD13).

a) Default setting
Factory default value is shown below.
IP address : 192.168.0.10
Default gateway : 192.168.0.254
Subnet mask : 255.255.255.0
Port number : 10940
b) Changing the IP address
IP address can be changed by using SLS project Designer. Refer
to section 7.13 and 7.9.1 for details, refer to the user’s manual.
(12)Function to configure SE2L by SD card
Configuration generated by SLS Project Designer can be saved in
a SD card. It is possible to transfer the setting directly from the SD
Card to SE2L without connecting to a PC.The type of SD card should
be Micro SD card when this function is used.
Create a project file with set the serial number and password of
the SE2L and save it on the SD card using SLS Project Designer.
When the SD card is inserted to the specified SE2L, settings are
automatically transferred. Setting will not be transferred to the
unspecified SE2L.
(13)Master-Slave Function
Maximum 4 units of S E2L can be interconnected using RS-485
for Master/slave operation. One unit will function as a master unit
communicating with up to 3 units that function as slaves via safety
communication channel. Use the SLS Project Designer to configure
the devices.
Area switching of the slave unit is linked with the master unit while
the slave units transmit the object detection information to the master
which controls the OSSD. It is also possible to use each slave unit’s
OSSD. Figure 5 shows the connection example.

6.Light interference
SE2L uses pulsed laser for object detection. Light sources in the
surrounding could interfere with its operation leading to false
detection. User should examine the surroundings environments
before installing the SE2L . Some of the light sources that could
interfere with SE2L are as below.
①Incandescent light
②Fluorescent light
③Stroboscopic light
④Flashing beacon
⑤Sunlight
⑥Infrared light sources
In case the light source cannot be avoided during the operation,
SE2L should be installed with the light source located at ±5 degrees
or more from the detection plane to prevent the interference (Figure
6).

7. Mutual interference
Cautions are required while using two or more units of SE2L or
identical products as pulsed laser signal from one another could lead
to false detection. Figures below show the installation method for
avoiding the mutual interference.
(1) Changing the height of installation
Install at different heights to separate the mutual detection plane by 5
degrees or more.
5 °or more
5 °or more
