The SE2L is a safety sensor that can detect approach.
Stop area can be made smaller by detecting approach
at the additional protection zone to start slowdown.

(Conventional conguration of one protection zone +
two warning zones is possible)

Master slave function, rst in its industry

A maximum of four SE2Ls can be interconnected using
RS-485 for master/slave operation.

RF2 force-guided relay
(2-pole)

Can be used as interface
relays to send input
signals to a controller, or to
amplify current for driving a
contactor.

RF1V force-guided relay
(4-pole/6-pole)

Can interrupt a small load
directly.

Access Protection

Allows only objects to pass
through. Detects the access
of humans.

Doo

An SE2L can monitor two separate hazardous areas to
stop machines when detecting the access of humans. No
reective sensor is necessary, thus eliminating the need
of optical axis alignment. Can replace two light curtains.

Reference monitoring function ensures safety by
detecting the positional change of SE2L or reference
boundary, such as a door’s opening/closing status.

Ensures safety at entrance of works. Override function enables restart from unintended stop.

By disabling some areas of protection zone, muting
function allows objects to enter the hazardous area
without stopping the machine.

FS1A Safety Controller LD6A LED SignaLight Towers

A variety of safety products can be
connected to the controller equipped
with various control logics.

With override function, when stopped by errors
at muting status, the work can be moved easily.

Used to indicate the status of
processes. Visible even at a distance.

Collision Avoidance

A maximum of 32 area patterns

Protects humans from colliding.
Also prevents loads on from
falling.

Utilize distance measurement data

A maximum of 32 area patterns can be congured/
switched according to the mobile application such
as AGV, ensuring the optimum protection in various
applications.

Monitors external output equipment

During safety protection, the SE2L can send out
distance measurement data through the Ethernet
port, in order to obtain the data of the obstacles.

Encoder inputs

Force-guided relay

Pulse signals from an incremental encoder can be sent
to the SE2L directly without a controller, enabling to
switch areas easily depending on the speed.

Emergency Stop Switches
XW/XN/X6

A variety of models to choose from.

Supports area conguration

Excellent Usability

Easy-to-use conguration and useful functions for simple
and comfortable maintenance.

Check detection status with video

Teaching function enables automatic area
conguration by referring to obstacles such as walls
and columns. Area can be congured easily even
with complicated background.

Detection log report reduces maintenance

No human in the
protection zone

Area data and distance measurement data can be
recorded while monitoring on PC. Video of detection
status can be replayed with the le.

Human approaching
the protection zone

Human inside the
protection zone

Reduce maintenance and start-up time

Area data and function settings
created on PC can be transferred
to the SE2L using not only by
USB cable but also micro SD
card.

Stable operation even in dusty environment

Checks dust in air with signals
and reduces unintended
detection. Safety function is not
impaired.

Operational status is displayed on the SE2L. It can
also be displayed on PC to monitor errors and data
log for easy trouble shooting.

SE2L Safety Laser Scanner

Operating Principle

With the SE2L, the distance is measured by the Time
of Flight (TOF) principle. The SE2L sends out very short
pulses of infrared light. The mirror rotated by the motor
sends the infrared light within the scanning range of 270º,
and is reected back from an object within the range.

Laser

Distance to object (L)

The distance can be calculated as follows:

× c × T

L = Distance to the object

c = Speed of light
T = Time difference

Scanning Area

A scanning area of the SE2L consists of:

•Aprotection+twozones

•Aprotectionzone

•Twoprotectionzones

Up to 32 sets of scanning areas can be congured.
A software SLS Project Designer supplied with the SE2L
is used to congure the protection and warning zones,
providing excellent user interface. Automatic zone
conguration by referring the boundary is also possible.
See SE2L User's Manual “7. Function Conguration of
SE2L” for details. The latest version of the software can be
downloaded from IDEC website.

Area Switching

The SE2L can store up to 32 area patterns. The number
of maximum congurable areas depends on selected
functions such as scan area mode and muting.

Response Time

The OFF response time (default: 60ms) for the OSSD signal
and ON response time (default: 270ms) can be congured
by using the SLS Project Designer. The response time for
WARNING 1, 2 is the same as the response time for OSSD.
In dual protection mode, different response time can be
set for protection zone 1 and 2 each. The stability of the
SE2L can be increased by setting a long response time,
but a long safety distance is required (see User's Manual

4. Application Examples of SE2L). Before setting the
response time, the user must perform a risk assessment
thoroughly. The congurable response time is shown in the
table below. Be sure to add the time taken to switch areas
(30 ms).

Light Interference

SE2L is a sensor that transmits pulsed laser for obstacle
detection. Interfering light sources may lead to false
detection. Before using the SE2L, examine the surrounding
environment. If the SE2L must be used under the
environment shown below, install the SE2L so that the light
source is located more than ±5 degrees from the sensing
plane to prevent light interference.

a) Incandescent light
b) Florescent light
c) Strobe light

Highly Reflective Background

Highly reective backgrounds may cause false detection
causing the SE2L to detect a longer distance than the
actual distance. If an operating environment with a highly
reective background cannot be avoided, an additional
distance of 200 mm, in addition to the 100mm additional
safety distance, is needed when conguring protection or
warning zones.

SE2L Safety Laser Scanner

OSSD

In SE2Ls, 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. The self-diagnosis function of
the OSSD detects abnormality by switching off OSSD 1 to
OSSD 4 at intervals of 300 µs maximum. Be sure to use a
force-guided relay, converter, or controller that does not
respond to this self-diagnosis function.

Safety Precautions

Safety Precautions

For correct use of the SE2L, take note of the following
precautions.

x SE2L is a AOPDDR (Active Optoelectronic Protective

Device responsive to Diffuse Reection) that detects
diffused emitted light within the protection zone.

x Perform tests before operation to check the function and

performance of the SE2L.

x SE2L is designed to protect human beings or systems by

monitoring the hazardous area. It is not designed for the
protection from high speed objects or electromagnetic
radiation.

x To maintain the degree of protection and to prevent injury

or death, do not modify or disassemble the SE2L.

x IDEC does not warrant any problems that were caused by

modication or disassembly of the SE2L.

x The operator must be a person qualied to operate

the SE2L. The operator must be trained and be able to
operate the SE2L correctly.

x The administrator must provide continuous training to the

operator for correct use of the SE2L.

x The administrator must understand the user's manual

and be responsible for ensuring appropriate operating
conditions for SE2L.

x SE2L has been manufactured and shipped under strict

quality control. If you nd any defect in the product,
contact distributor or sales representative.

x IDEC does not take responsibility for damage caused

by improper use of the product by customers or third
parties. IDEC cannot take responsibilities for any loss
from the misuse except for the responsibilities governed
by law.

x To examine the object detecting performance, use a test

piece the size equivalent to the minimum detectable
object.

x Error occurs when detection capability is below 30% due

to homogenous dirt on the optical window. The operator
must keep the windows clean.

x When the interlock function is active, make sure that the

surrounding environment, especially within the protection
zone, is safe before resetting the interlock.

x While SE2L 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.

x SE2L and its accessories are subject to change for

improvement without prior notice.

x Dispose the SE2L as industrial waste or in accordance

with the local regulations.

Operating Environment

x Make sure that the operating environment is within the

range of the specications (temperature, humidity, light
interference) described in User’s Manual, otherwise
malfunction or degradation of detection performance may
result.

x Do not use the SE2L near a machine that may generate

strong radio waves. It may interfere with the operation of
the SE2L.

x Do not use or install the SE2L where dust, smoke, or

corrosive chemical substances exist. Using the SE2L
under these environments may lead to degradation of
detection performance.

x The SE2L is for indoor use only.

Installation

x Install the SE2L on a stable surface or structure to

prevent displacement of the sensor.

x Install the SE2L securely so that screws do not loosen

due to shock or vibration. (Recommended tightening
torque 3 N∙m). Displacement may degrade protection
performance.

x Determine the safety distance before installing the SE2L.

After installing the SE2L, use a test piece for all protection
zones to check the sensing functions.

x After installing the SE2L, use protective materials such as

safety guards and light curtains to prevent entry into the
protective zone.

x The following switches must be installed far from the

protection zone, so that the operator can operate the
switches while overseeing the entire protection zone.

* Switch to reset the interlock function
* Switch to start muting function
* Switch to start override function

x If several SE2Ls are installed on the same sensing plane,

mutual interference may occur.

x Provide enough space for installation and maintenance of

the SE2L.

x Do not cover the front of the optical window with glass or

transparent cover, otherwise detection characteristics of
the SE2L may be impaired.

x Minimum sensing width differs according to the distance.

Wiring

x Be sure to turn off all power before wiring.
x When using converter power, make sure to use power

that satises 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.

x All input/output cables must be located away from power

cables and high voltage cables.

x To 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.

x Both the OSSD1 and OSSD2 outputs should be

connected to safety-related machines or control system.
When OSSD3 and OSSD4 are used, connect the outputs
in the same manner.

x Use shielded cable for the connection between OSSD

signals and safety-related machines or systems.

Installation

x A password is used for conguring the safety function.

Only an administrator or operator should be able to set

safety functions.
x SE2L will not operate without initial conguration.
x Perform test operation and check the conguration

before using the SE2L.
x The stability of the SE2L 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.
x The operator must record the changes made in the

conguration. SLS Congurator report function is

available. For details, see the User's Manual.

Testing and Maintenance

x The operator should perform the following tests or

maintenance based on the checklist described in the
User's Manual.

1) Pre-operation inspection

2) Operation inspection

3) Daily inspection

4) Periodic inspection
The checklist in the User's Manual is a basic guideline

for performing tests and maintenance. The operator
should perform additional tests and maintenance if

necessary.
x Stop the machine if failure occurs during tests.
x Clean the optical window if any dirt is found, and ask for

repair if damaged. Refer to the User's Manual for details.
