rules and regulations, laws of respective nations, states or districts when 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.
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 to operate normally is under 30%. SE2L will
report error if the pollution exceeds the stated limit. Always keep the optical window in clean condition
to avoid the error.
Before resetting the interlock of SE2L, user must ensure the surrounding is safe especially the protected
area.
Apply sufficient measures to ensure safety of the protected area when decommissioning SE2L.
Protective materials such as guards or light curtain should be used to prevent the passage to 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.
Read the following guidelines for correct use of the SE2L. Proper handling and
usage will ensure the SE2L to operate accordingly.

SE2L User’s Manual (SE9Z-B1865)

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.
2.2 Operating environment
Make sure that SE2L’s operating environment is within the stated specification (temperature, humidity,
vibration, ambient light, etc.)
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.
2.3 Installation of SE2L
Install SE2L on a firm surface or structure to avoid displacement.
SE2L should be firmly mounted using the screws (recommended torque for screws is 3N･m). Shock
and vibration should not loosen the mounting. Detection may fail if actual protection zone differs from
the intended zone due to displacement of SE2L.
Safety distance should be determined before installing SE2L. User must verify the function of SE2L
after installation by placing a test piece at all the positions of protection zone (refer to chapter 4 for the
details on the safety distance calculation for various applications).
When installing 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.
Mutual interference can occur when identical SE2Ls are mounted at the same detection plane. Refer to
chapter 5 for countermeasures to avoid mutual interference.
SE2L should be mounted at the location which has sufficient space for maintenance.
Do not add any protective materials such as, glass and transparent cover, in front of the optical window.
This could lead to loss of detection capability of the SE2L.
Minimum detectable width varies with the distance. Refer to chapter 10 for details.
2.4 Wiring
Switch off all the power supplies during wiring.
When a converter is used for supplying the power, make sure it fulfills the following requirements.
A rated output voltage within the range of 24V DC ±10% (SELV circuit, Category II).
Reinforced insulation or double insulation for the primary and secondary circuit.
Holding time of the output should be above 20ms.
The power supply complies with the requirements of electromagnetic compatibility
regulations (EMC) of the respective country, state and district.

SE2L User’s Manual (SE9Z-B1865)
11
All the input/output signal cables should be installed away from machines power lines and high-
voltage cables.
Use the OSSD signal of SE2L to control safety-related machines or control 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.
2.5 Configuration
Configuration of safety functions are password protected. Only authorized users with password are
allowed to configure SE2L.
SE2L does not operate without initial configuration.
Pre-operation tests should 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 and saved. Use the report function in the SLS
Project Designer for this purpose. (page 100)

3.3 Operation principle
Figure 3-4 Scanning range
Figure 3-4 shows the scanning range of SE2L. Protection zone and warning zones are configured using
the SLS Project Designer application software. Any object or human beings entering the protection zone will
lead the OSSD signal to change from ON-state to OFF-state. Similarly, an object detected in the warning
zones will lead the warning signals to change to OFF-state.
Distance to the object is measured using the Time of Flight (TOF) principle. Pulsed laser beams are
radiated into the scanning range of 270º by the rotating motor. These pulsed laser beams are reflected back
by objects inside the scanning range. The duration of reflected beams are used for distance calculation as
shown below:
Where, L＝Distance of the object
C＝Speed of the light
T＝Time difference

The operating principle of TOF is schematically shown in Figure 3-5. The angular resolution of SE2L is
0.125°.
Figure 3-5 TOF operation principle
3.4 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.
Combination 1: Protection zone, Warning zone 1 and Warning zone 2
Combination 2: 2 Protection zones (Dual Protection)
In dual protection mode, two protection areas can be configured but it is not possible to configure the
warning zones Protection and warning zones can be configured by using SLS Project Designer. Refer to
Chapter 7 for configuration details.
3.4.1 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 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 3-6 and 3-7 show the examples of protection zone configured using manual mode and teaching mode
respectively. User can configure these zones accordingly to ensure hazardous area is completely protected.

User should verify the detection capability using an actual object.
User should verify the configuration before actual operation.
The configured zone should be of minimum safety distance or more.
Minimum possible detectable width changes according to the distance.
Additional distance must be taken into account while configuring the protection
zone.
