Procedures that could lead to dangerous situation, criticalinjury ordeath if not carried out properly.

Refer SE2L user's manual for details.
Read section 12 "Instruction for using SE2L for the ﬁrst timeafterpurchase" when using the device for the ﬁrst time.

1. Safety precautions
DangerPlease 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. Opticalradiations 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 bymonitoring 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 thefunctionality 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 theoperator 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 thelocal safety requirements, standards, rules and regulations, lawsof respective nations, states or districts when the SE2L is used in asafety-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. I D E C
cannot take responsibilities for any loss from the misuse except for
the responsibilities govened by low.

2017.11● 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 thestated 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 priornotice for the improvement.
● SE2L should be disposed as industrial waste or in accordance withthe local disposal directives.
● Do not drop the product. Otherwise, the product may be damaged,
lead to failure and the performance will be degraded. Injury may
also be caused.

(2) Operating environment
Danger● Make sure that SE2Lʼs operating environment is within the statedspeciﬁcation (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 suchenvironments may decrease the detection capacity of SE2L.
● This product is for indoor use only.

(3) Installation
Danger● Install t h e

SE2L on a ﬁrm surface or structures to avoid
displacement. Also, do not step on or hung on SE2L after installation.
● The SE2L should be ﬁrmly mounted using screws. Shock andvibration should not loosen the mounting. SE2L will not operateproperly 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 byplacing 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 thewhole 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 spacefor maintenance.
● Do not add any protective materials such as glass, transparent
cover etc in front of the optical window. This would lead to loss ofdetection capability of the SE2L.
● Minimum detectable width varies with the distance.

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 andsecondary circuitc) Holding time of the output should be above 20msd) The power supply must comply with the requirements ofelectrical safety and electromagnetic compatibility (EMC)
regulations of the respective country, states and district.
● All the input/output signal cables should be installed away frommachines 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 asthese are non-safety signals.
● Both the OSSD1 and OSSD2 outputs should be connected to thesafety-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 andsafety-related machines or systems.

Interlock is a function to prevent automatic restart of the OSSD
signal switching from OFF-state to ON-state. OSSD1/2,RES̲REQ1
and RESET1 are for protection zone 1; OSSD3/4,RES̲REQ2 and
RESET2 are for protection zone 2 when setting the sensor by SLS
Project Designer. We use OSSD, RES̲REQ and RESET in the restof 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 E 2 L is in the lockout state due to error, OSSDs willremain in OFF-state even if the interlock function is disabled.

5.Functions
SE2L's function can be conﬁgure using the SLS Project Designer.

(1)Scanning area

Scanning area of S E 2 L consists of protection zone and warningzones. Maximum 32 sets of area can be conﬁgured. Further, two
combinations for protection and warning zones can be selected forthe operation.
a) Protection zone, Warning zone 1 andWarning zone 2b) 2 Protection zones (Dual Protection)
In dual protection mode, two protection
areas can be conﬁgured therefore twomchines can be protected by one unitof S E 2 L .Protection and warning zones
can be conﬁgured by using S L S ProjectFig-1. Protection zone conﬁgured
Designer.
using manual mode

● Protection zone

Warning zones are non-safety zones and are connected to Warning1 andWarning2 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 orobjects 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

Ethernet

SD cardthe OSSD signal can be used as the emergency stop signal. Figure
1 shows the examples of protection zone conﬁgured using manualmode and teaching mode respectively. User must conﬁgure thesezones accordingly to ensure hazardous area is completely protected.

Protection zone is safety-critical and directly connected to the OSSD
signal. When an obstacle is detected in the protection zone, S E 2 L
will switch the OSSD from ON-state to OFF-state (which should
trigger a switch to stop a machine or AGV). For mobile applications,

When interlock function is set to manual restart mode, even if thedetected obstacles or system error is removed, OSSD signals willremain in OFF-state. An external reset input signal is required torelease the interlock which allows the S E 2 L to switch to normal
operation. RES̲REQ signal will be switched to ON state whenobstacles disappear from protection zone. S E 2 L will resume normal
operation only after conﬁrming the reset signal (RESET). The
duration of the reset signal should be more than 500ms. After RES̲REQ 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 remainin 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 RES̲REQ signal
switches to ON-state after the S E 2 L completes initial routines andready 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 fromthe controlled machine or automated guided vehicle (AGV). EDM
is conﬁgured using the S L S 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 tomatch the userʼs 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 S L S project designer. Whenmuting inputs fulﬁll the muting start conditions, SE2L will suspend thesafety 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 timeinterval. 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 mutingtime.
c) Objects are detected in the protection zone which is not coveredby the muting zone.
d) Error is detected by the self-diagnostics function.
e) During muting state when the area is switched to another area.

＜ Area switching sequence ＞
When area sequence is disabled, S E 2 L can switch from an area toany other areas (Figure 3) whereas it can only switch to speciﬁed
areas if area sequence is enabled. (Figure 4).
Area3(6)Reference monitoring function

Reference monitoring is a function to monitor the displacement of theSE2L 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 isdetected, and also if the distance between S E 2 L and the reference
structure changes. This function is compulsory for verticalapplications.

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 individuallyfor each area using the S E 2 L 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 foreach protection area.
When longer response time is conﬁgured, the stability of S E 2 L canbe 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.
Table-1. Response time of SE2L

● Muting override function

Muting override is a function to recover S E 2 L when the OSSD isswitched to OFF state due to muting related errors by temporarilysuspending the safety function. Override function is active when theoverride input (OVERRIDE 1/2) and the reset input (RESET1/2) areswitched in a sequence.

(9)Area switching

A maximum of 32 sets of area can be conﬁgured in SE2L. However
the maximum conﬁgurable area number diﬀers depending on theselected 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 S E 2 L for switching the area.
Each signal has a pair of normal and inverted signal. For example,
it is necessary to provide both input signal IN̲A and inverse IN̲
A signal to switch the area. Error will occur if IN̲A and inverse IN̲
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 S E 2 L . It is also possible to
conﬁgure area input delay. Conﬁgure the necessary delay required
for the system to provide stable input signals to S E 2 L . 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 throughthe speed monitoring of increment encoder signal connected to
SE2L.

8. High reﬂective background
Measured value will be longer than the actual distance of the object
due to high reﬂective background leading to wrong detection.
When high reﬂective background cannot be avoided in the working
environment, additional distance of 200mm is necessary while
conﬁguring the protection and warning zones (Figure 13).

* Speciﬁcation of Distancetolerance is “+100mm”.

7. Mutual interference

Cautions are required while using two or more units of S E 2 L or
identical products as pulsed laser signal from one another could leadto false detection. Figures below show the installation method foravoiding the mutual interference.

(1) Changing the height of installation

Install at diﬀerent heights to separate the mutual detection plane by 5degrees or more.

9. Limited detection capability zone
The limited detection capability zone is deﬁned as a region between
the optical window and start of the detection zone. The limited
detection capability zone of the S E 2 L is 90mm from the origin of
SE2L (Figure 14). Presence of object with low reﬂectance may not be
detected in this zone.

6.Light interference
SE2L uses pulsed laser for object detection. Light sources in thesurrounding could interfere with its operation leading to false
detection. User should examine the surroundings environments
before installing the S E 2 L . Some of the light sources that could
interfere with SE2L are as below.

Maximum 4 units of S E 2 L 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 unitʼs
OSSD. Figure 5 shows the connection example.
