Door

An SE2L can monitor two separate hazardous areas to stop machines
when detecting the access of humans. No reflective 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 thehazardous area without stopping the machine.

E-115

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

Optical window can be replaced on-site

Operational status is displayed on the SE2L. It can also be displayed on
PC to monitor errors and data log for easy trouble shooting.
Also, the detection log can be displayed not only by numerical values
but can be displayed intuitively by mapping.

Cover Bracket

Optical window can be replaced by the user, reducing downtime andcost. A cover bracket to protect the SE2L for damage by collision is
also available.

Optical window contamination countermeasure
When an error occurs, I/O output can be set to turn on.
Especially when an optical window is contaminated,
it is possible to output a warning alert before stopping
due to contamination.
Also, the PC monitor displays the position of the contamination when the optical window is contaminated,making maintenance and countermeasures easier.

Operating Principle

Area Switching

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 reflected back from an object within the range.

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

The distance can be calculated as follows:
1
L = − ×c×T
2

L = Distance to the object
c = Speed of light
T = Time difference

Note 1: Muting function modes cannot be used when encoder input mode isselected.
Note 2: Among the eight input patterns, at least one pattern must be used for
encoder input. Other seven remaining patterns can be selected to be
used as a static input or not in use. A pattern with encoder input mode
has up to 128 sets of area.

Input combination for area switching

Scanning Area
Scanning area of SE2L consists of protection zone and warning zones
or only a protection zone. In both cases, maximum 32 sets of area canbe configured (128 area sets when encoder input function is used).
A software SLS Project Designer supplied with the SE2L is used toconfigure the protection and warning zones, providing excellent userinterface. Automatic zone configuration by referring the boundary is
also possible. See SE2L User's Manual “7. Function Configuration of
SE2L” for details. The latest version of the software can be downloaded
from IDEC website.

The OFF response time (default: 60ms) for the OSSD signal and ON
response time (default: 270ms) can be configured by using the SLS
Project Designer. The response time for WARNING 1, 2 is the sameas 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 configurable response timeis shown in the table below. Be sure to add the time taken to switch
areas (30 ms).

In SE2Ls, the OSSD signal has a self-diagnosis function that tests thesignal periodically to detect malfunction. The OSSD signal will turn OFF
when a error is detected due to the self-diagnosis function. The selfdiagnosis function of the OSSD detects abnormality by switching off
OSSD 1 to OSSD 4 at intervals of 300 µs maximum. Be sure to use aforce-guided relay, converter, or controller that does not respond to thisself-diagnosis function.

Safety Precautions
For correct use of the SE2L, take note of the following precautions.
• SE2L is a AOPDDR (Active Optoelectronic Protective Device responsive to Diffuse Reflection) that detects diffused emitted light within
the protection zone.
• Perform tests before operation to check the function and performanceof the SE2L.
• SE2L is designed to protect human beings or systems by monitoring
the hazardous area. It is not designed for the protection from highspeed objects or electromagnetic radiation.
• To maintain the degree of protection and to prevent injury or death,
do not modify or disassemble the SE2L.
• IDEC does not warrant any problems that were caused by modification or disassembly of the SE2L.
• The operator must be a person qualified to operate the SE2L. The
operator must be trained and be able to operate the SE2L correctly.
• The administrator must provide continuous training to the operator forcorrect use of the SE2L.
• The administrator must understand the user's manual and be responsible for ensuring appropriate operating conditions for SE2L.
• SE2L has been manufactured and shipped under strict quality control.
If you find any defect in the product, contact distributor or sales
representative.
• IDEC does not take responsibility for damage caused by improperuse of the product by customers or third parties. IDEC cannot takeresponsibilities for any loss from the misuse except for the responsibilities governed by law.
• To examine the object detecting performance, use a test piece thesize equivalent to the minimum detectable object.
• Error occurs when detection capability is below 30% due to homogenous dirt on the optical window. The operator must keep thewindows clean.
• When the interlock function is active, make sure that the surrounding environment, especially within the protection zone, is safe before
resetting the interlock.
• While SE2L is removed, a protective measure must be taken to
ensure safety within the protection zone. To prevent entry into thedanger zone, use protective materials such as a safety guard or lightcurtain.
• SE2L and its accessories are subject to change for improvement
without prior notice.
• Dispose the SE2L as industrial waste or in accordance with the local
regulations.
• 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.

• Take measures on the network system side to prevent unauthorizedaccess to SE2L from external devices. Under no circumstances shall
IDEC Corporation be held liable or responsible for any indirect orconsequential damages and expenses resulting from unauthorizedaccess.

Operating Environment• Make sure that the operating environment is within the range of thespecifications (temperature, humidity, light interference) describedin User’s Manual, otherwise malfunction or degradation of detection
performance may result.
• Do not use the SE2L near a machine that may generate strong radio
waves. It may interfere with the operation of the SE2L.
• Do not use or install the SE2L where dust, smoke, or corrosive chemical substances exist. Using the SE2L under these environments maylead to degradation of detection performance.
• The SE2L is for indoor use only.

Installation• Install the SE2L on a stable surface or structure to prevent displacement of the sensor.
• Install the SE2L securely so that screws do not loosen due to shockor vibration. (Recommended tightening torque 3 N∙m). Displacement
may degrade protection performance.
• Determine the safety distance before installing the SE2L. After installing the SE2L, use a test piece for all protection zones to check thesensing functions.
• After installing the SE2L, use protective materials such as safety
guards and light curtains to prevent entry into the protective zone.
• The following switches must be installed far from the protection zone,
so that the operator can operate the switches while overseeing theentire protection zone.
* Switch to reset the interlock function* Switch to start muting function* Switch to start override function• If several SE2Ls are installed on the same sensing plane, mutualinterference may occur.
• Provide enough space for installation and maintenance of the SE2L.
• Do not cover the front of the optical window with glass or transparent cover, otherwise detection characteristics of the SE2L may be
impaired.
• Minimum sensing width differs according to the distance.

Safety Precautions
WiringTesting and Maintenance• Be sure to turn off all power before wiring.
• When using converter power, make sure to use power that satisfies
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 eachcountry, state, and district.
• All input/output cables must be located away from power cables andhigh voltage cables.
• 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.
• Both the OSSD1 and OSSD2 outputs should be connected to safetyrelated machines or control system. When OSSD3 and OSSD4 areused, connect the outputs in the same manner.
• Use shielded cable for the connection between OSSD signals andsafety-related machines or systems.

• The operator should perform the following tests or maintenancebased on the checklist described in the User's Manual.
1) 	Pre-operation inspection2) 	Operation inspection3) 	Daily inspection4) 	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.
• Stop the machine if failure occurs during tests.
• Clean the optical window if any dirt is found, and ask for repair if
damaged. Refer to the User's Manual for details.

Controllers• A password is used for configuring the safety function. Only an administrator or operator should be able to set safety functions.
• SE2L will not operate without initial configuration.
• Perform test operation and check the configuration before using the
SE2L.
• 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.
• The operator must record the changes made in the configuration. SLS
Configurator report function is available. For details, see the User's
