2. Safety precautions


Read the following guidelines for correct use of the SE2L. Proper handlingand usage will ensure the SE2L to operate accordingly.

2.1 General precautions


SE2L is designed to protect human begins or systems by monitoring the hazardous area. It is notdesigned for the protection from high speed objects or the electromagnetic radiation.

Perform pre-operation tests in order to verify the performance of SE2L.
Do not modify or disassemble SE2L. Such modifications will affect the detection capability leading toinjuries or death.



Do not modify or disassemble SE2L to maintain its housing rating. Such modifications will void thewarranty.

The person-in-charge should be qualified to operate SE2L. The person must be trained, on safety
requirements with necessary cautions for handling the device.

The person-in-charge should train the user with correct installation, operation, inspection andmaintenance procedures.

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 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 thesmallest object that is intended to be detected during the operation.

Maximum level of homogeneous pollution for SE2L to operate normally is under 30%. SE2L willreport 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 thehazardous 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.
Do not drop the product. Otherwise, the product may be damaged, lead to failure and the performance

SE2L User’s Manual (SE9Z-B1865)8will be degraded. Injury may also be caused.



Take measures on the network system side to prevent unauthorized access to SE2L from external
devices. Please note that under no circumstances shall IDEC Corporation be held liable or responsible
for any indirect or consequential damages and expenses resulting from unauthorized access.

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 arepresent. 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. Also, do not step on or hung on SE2L
after installation.

SE2L should be firmly mounted using the screws (recommended torque for screws is 3N･m). Shockand vibration should not loosen the mounting. Detection may fail if actual protection zone differs fromthe 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 thedetails 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 awayfrom the protection zone.

Mutual interference can occur when identical SE2Ls are mounted at the same detection plane. Refer tochapter 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.

SE2L User’s Manual (SE9Z-B1865)
9



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.



All the input/output signal cables should be installed away from machines power lines and highvoltage 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 areallowed 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 thedetection capability towards moving objects. User must perform risk assessment before using thisfunction.



Changes made during the configuration must be recorded and saved. Use the report function in the SLS
Project Designer for this purpose. (for detail, refer to section 7.9.3)

User must check the operations of this user configurable product on user's responsibility. Under nocircumstances shall IDEC Corporation be held liable or responsible for the operations of the functions

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 willlead the OSSD signal to change from ON-state to OFF-state. Similarly, an object detected in the warningzones 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 areradiated into the scanning range of 270º by the rotating motor. These pulsed laser beams are reflected backby objects inside the scanning range. The duration of reflected beams are used for distance calculation asshown below:

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 thewarning 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 isdetected in the protection zone, SE2L will switch the OSSD to OFF-state (which should trigger a switch tostop 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.

In dual protection mode, two protection zones can be configured independently. SE2L will monitor thesezones simultaneously. OSSD1 and OSSD2 are dedicated to protection zone1 and OSSD3 and OSSD4 arededicated to protection zone2.
Figure 3-8 shows an example of the dual protection zone configuration. Warning zones cannot be
configured in dual protection mode.

3.4.2 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. Figure 3-9 shows an example of warning zone
configuration.

3.5 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 3-1 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 andinverted signal. For example, it is necessary to provide both input signal IN_A and inverse IN_A signal toswitch 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 toprovide stable input signals to SE2L. The default value is 30ms.
There are maximum 5 input pairs (a pair is 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 (for detail, refer to section 3.6.4 ).Maximum
configurable area in encoder input mode is 128.

3.6 Incremental 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 byencoder's phase A and phase B signals having the phase difference of 90°. Speed and rotating direction ofboth encoders are constantly monitored to detect abnormal travel and stop the AGV.
Incremental encoder output signals should be connected to the respective input terminals of SE2L. There
are two patterns of signals generated by the combination of Phase A and Phase B of encoders depending on
the direction of travel (Figure 3-10). In the first pattern, Phase B is 90 degrees ahead of Phase A wherein, at
the rising edge of Phase A, state of Phase B is “H”. This pattern is considered as positive direction (forward
motion). In the second pattern, Phase B lags behind Phase A by 90 degrees and the state of Phase B at therising edge of Phase A is “L”. This is considered as negative direction (backward motion).

Figure 3-10 Input signal through Incremental encoder

SE2L User’s Manual (SE9Z-B1865)
23

3.6.1 Pulse per cm travel generated by incremental encoders
When AGV travels, increment encoder generates pulses due to the transmission ratio between AVG tires
and increment encoder frictional wheel. Pulse count per cm depends on AGV's speed.

Figure 3-11 Calculation of pulse count for per centimeter travel

AGV tire diameter : 40 cm

Frictional wheel diameter mounted in increment encoder: 5 cmIncrement encoder pulse number per revolution : 1000 pulse

AGV tire circumference = Diameter × Circumference ratio = 40 cm × 3.14 = 125.6 cm
AGV tire's one rotation is equivalent to 8 rotations of frictional wheel. This equals to the 8,000 pulses ofincrement encoder.
From above, increment encoder pulse count per cm is obtained as
8,000/125.6 = 63.7
While setting encoder parameters (Encoder 1 Pulse and Encoder 2 Pulse) in SLS Project Designer, set theencoder pulse count after rounding the calculated value to nearest whole number (64 in this case).
In the explanation above, the transfer method of the rotation was based on the frictional wheel. Samemethod can be applied for other cases to estimate the pulse count generated for one rotation of the wheel.

SE2L User’s Manual (SE9Z-B1865)
24



User should verify the proper area switching through encoder inputs.



Always use 2 units of increment encoder. It is not possible to detect the failure ofincrement encoder or abnormal travel of the vehicle with single unit.



Use separate sets of cable to connect outputs from incremental encoder 1 and 2 to therespective encoder input terminals of SE2L.



Separate the power supply cables and power source of each incremental encoder.
Output pairs of encoder connection should match the input pair of SE2L.



Do not wire other power lines parallel to encoder and SE2L or wire in the same duct.
There is a possibility of noise disturbance.

3.6.2 Recommend increment encoder specification
・ Phase setting 90° dual channel rotary encoder
・ Power supply: 24V DC
・ Output : Complementary output
・ Protective class : IP 54 or more・ Output cable : Twist pair/ shield cable・ Maximum pulse frequency : 100 kHz

・ Minimum pulse frequency : 50 pulse / cm
3.6.3 Tolerances allowed for encoder
When AGV travels in a forward direction, speed input through the two increment encoder will be same as
the original pulse frequency. However, there are cases when two speed input values may differ, such as while
cornering and due to AGV tire exhaustion. The difference between two input speeds should not exceed theerror tolerance for more than a fixed period of time. Set the error tolerance in the range of 0 to 80%.
Of the two speeds, the larger value will be considered for vehicles speed calculation. When permitted error
tolerance exceeds the fixed period OSSD will go to OFF state. Tolerance period differs according to thevehicle speed as shown in table 3-3.

3.6.4 Area switching by encoder input
When encoder setting is enabled, four patterns can be selected from two available external inputs. For
each pattern, select either to use as static input or the encoder input or not used. It is necessary to select atleast one pattern for encoder input.
Further, patterns can be increased to 8 patterns by activating the “8 patterns (Input E Enable)” checkbox.
For encoder input pattern maximum 128 sets of area switching can be performed for the range of speed.
Encoder setting is enabled by the SLS Project Designer, as shown in Figure 3-12. For using the SLS Project
Designer refer to chapter 7.
Set the error tolerance and encoder pulse count for per cm travel.
The minimum and maximum speed is automatically calculated from the pulse count and maximum pulse
frequency (100 kHz). Next, select the input patterns to use as static input or for the encoder input or not used.
Figure 3-12 shows an example of encoder input setting. In this example, pattern 1 and pattern 2 are used asstatic input, pattern 3 is used as encoder input and pattern 4 is not used.

Figure 3-12 Example of pattern switching through encoder input
Next, divide the speed into number of ranges and specify the area number for each range. An example isshown below (maximum 128 sets of area can be set). Same area cannot be specified for different speed
within a pattern. However it is possible to select same area for a different pattern.
Figure 3-13(a) shows the example of encoder input setting.
In this example, speed is divided into 4 ranges and each speed range is assigned Area 3 to Area 6.

Figure 3-13 (a) Example of encoder input setting

SE2L User’s Manual (SE9Z-B1865)

When the pattern is set for static input, area number and encoder velocity monitoring are configured.
Velocity monitoring monitors the encoder velocity and if it exceeds the specified limit OSSD will beswitched to OFF state. Further, it is also possible to individually monitor the speed of encoders by selecting
the independent check checkbox.
Figure 3-13(b) shows the example of static input setting. In this example, Area1 is assigned to the input
pattern and speed monitoring is enabled with the monitoring speed range -20 to 500cm/sec.

Figure 3-13 (b) Example of static input setting

3.7 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 thesignal periodically by switching it to OFF state for a brief period. 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 theymust be connected in the same manner.


OSSD is a safety related signal and should be connected directly to the relay or device
that switches the machine or vehicle under control.

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 connectedsimilarly.

Sufficient time for the machine or vehicle must be allocated to stop when configuring
the response time of OSSD.



User must verify the configuration before actual operation.

SE2L User’s Manual (SE9Z-B1865)
27



When OSSD is at ON state, the signal is 24V and the signal is 0V during OFF state.

3.7.1 Self-diagnostic function of OSSD
Self-diagnostic is a function to detect the malfunction in the output circuit by switching OFF the OSSD 1
to OSSD 4 for an interval of approx. 300μs. Therefore, safety-relay or power converter used must not
response to this diagnostic function. Figure 3-14 below shows the timing chart of the self-diagnostic functionof the OSSD during dual protection mode.

Figure 3-14 Timing chart of the OSSD’s self-diagnostic function
In single protection mode, self-diagnostic function is done for OSSD 1 and OSSD 2 signals only.

3.7.2 Lockout state
When an error is detected by the self-diagnostic function and SE2L cannot operate normally it willswitch to lockout state. During the lockout state, OSSD1/2, OSSD3/4, WARNING1, WARNING2 willswitch to OFF-state. After removing the error, SE2L can be reset by restoring the power to release from thelockout state.

3.7.3 Interlock function
Interlock is a function to prevent automatic restart of the OSSD signal switching from OFF-state to
ON-state. Automatic restart, manual restart and manual start interlock functions are configurable using the
SLS Project Designer.

SE2L User’s Manual (SE9Z-B1865)28

3.7.3.1 Automatic restart
SE2L will restart automatically when interlock function is disabled or only the start interlock function isenabled. When obstacle from the protection zone is removed, OSSD signals switch from OFF-state to
ON-state automatically. OSSD response times for ON and OFF states are configurable (See section 3.12).
However, if SE2L is in the lockout state due to error, OSSDs will remain in OFF-state even if the interlock
function is disabled.

Figure 3-15 Timing chart of automatic restart

In automatic restart configuration OSSD will automatically switch to ON state after
the object is removed. Confirm the safety while removing the object.

Configured response time should be sufficient for the machine or AGV to stop safely.

SE2L User’s Manual (SE9Z-B1865)29

3.7.3.2 Manual restart (Interlock enabled)
SE2L operates in manual restart mode when interlock function is set to manual mode. The OSSD signal
switches from ON-state to OFF-state, if SE2L detects any obstacle within the protection zone or detects any
system error. In this mode, even if the detected obstacles or system error is removed, OSSD signals willremain in OFF-state. An external reset input signal is required to release the interlock which allows the SE2L
to switch to normal operation.
SE2L will resume normal operation only after confirming the reset signal (RESET). The duration of thereset signal should be more than 500ms. Figure 3-16 shows the timing chart of the manual restart. After 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.

Figure 3-16 Timing chart of manual restartUser should verify that the detected obstacle is safely removed before resetting the
SE2L.



If restart interlock function is used to restart the machine, the reset switch should be
mounted away from the protection zone.



Falling to comply with the above could lead to critical injury or death.

Even after the object is removed from the protection zone, if the OSSD still
remains in OFF-state, check the error code and suggested solution (Refer to
Chapter 9).

Duration of reset input should not exceed 30s; otherwise it will be detected as
hardware malfunction.

SE2L User’s Manual (SE9Z-B1865)30

3.7.3.3 Manual start (Interlock enabled)
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 thereset input should be more than 500ms. Figure 3-17 shows the sequence of start interlock. Delay can be
configured in the range of 1s to 6s.

Figure 3-17 Manual start sequence

3.8 External device monitoring (EDM) function
EDM is a function that monitors the state of the input signal from the controlled machine or automatedguided 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 bealways inverse of the OSSD signal. EDM input signal ON/OFF delay is configurable to match the user’s
system. Figure 3-18 and 3-19 below shows the EDM circuit and EDM timing chart respectively.

Figure 3-18 EDM circuit

SE2L User’s Manual (SE9Z-B1865)
31

Figure 3-19 EDM timing chart
In dual protection mode, EDM2 circuit and timing chart for OSSD3 and OSSD4 are same as above.

3.9 Muting function
Muting function temporarily suspends the safety function in the configured zone of SE2L when thespecified 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 andend the muting function. Muting zone is configured using the SLS Project Designer (Refer to section 7.9.1).
When muting inputs fulfill the muting start conditions, SE2L will suspend the safety function within 60ms
and resume the safety function if they fulfill the muting stop conditions.

3.9.1 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 predefinedsequence within the pre-set time interval. However, the switching interval between two input signals
should not be 0 (Refer to figure 3-20).
The following configurations are necessary for the muting function. User can configure these by using the
SLS Project Designer.


Muting inputs sequence▶ Muting 1  Muting 2▶ Muting 2  Muting 1

Time interval between two inputs (T1)
▶ 1second▶ 3seconds▶ 5seconds▶ 10seconds

When using muting function in dual protection mode, Muting 3 and Muting 4 are configured in the similarway.

SE2L User’s Manual (SE9Z-B1865)
32

3.9.2 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 predefined (preset) maximum muting time T2 exceeds (1 minute and above) (Figure 3-20).
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 other area.
Figure 3-20 shows the muting sequence.
Maximum muting period (T2)
Maximum muting period can be selected from one of these values▶ 1 minute▶ 6 minutes▶ 12 minutes▶ Unlimited

When using the muting function in dual protection mode, Muting 3 and Muting 4 are configured in thesimilar way. Same applies for muting input sequence, time interval between inputs and maximum muting
period.

3.9.3 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 (RESET 1/2) are switched in a sequence. Figure 3-21 shows theoverride sequence.
Override start conditions▶ At least one of the muting inputs is in ON-state.
▶ Object is present in the protection zone.
▶ Time interval between override input and reset input is within 0.03s to 1s (T3).

Override stop conditions▶ Both muting inputs are in OFF-state.
▶ Override input or reset input is in OFF-state.
▶ When predefined maximum override time T4 exceeds.
▶ Error is detected by self-diagnostic function of the SE2L.
▶ During override state when area is switched to the other area.

Maximum override period (T4)

When using muting override in dual protection mode, Muting 3, Muting 4, Override input 2 and Reset
input 2 are configured in the similar way.
When muting function is enabled, user must ensure the safety of the protection zone.



Before using the muting function, user must perform risk assessment.



A qualified person should configure the appropriate muting period according to therequirement of the application. It is the user’s responsibility to properly perform the risk
assessment when configuring muting period to unlimited.



Failing to comply with the above could lead to critical injury or death.

3.10 Reference monitoring function
Reference monitoring is a function to monitor the displacement of the SE2L or the structure used as
reference boundary.

3.10.1 Area protection
An example of reference monitor function used for area protection is shown in figure 3-22. If reference
segments are configured on moveable objects (example: door) the OSSD will switch to OFF-state when thedoor position is changed.

SE2L

SE2L User’s Manual (SE9Z-B1865)35

3.10.2 Access protection
An example of reference monitor function used for access protection is shown in figure 3-23(a), (b).
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 structurechanges. This function is compulsory for vertical applications.

3.11 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. Thisfunction 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 3-24 (a) whereas
it can only switch to specified areas if area sequence is enabled. (Figure 3-24 (b)).
Area sequence function is recommended for control systems where switching area sequences can be
configured.

Figure 3-24 (a) Operation without area sequence

Figure 3-24 (b) Operation with area sequence

3.12 Response time
Response times of OSSD signal (Figure 3-25), OFF response time and ON response time areconfigurable individually for each area using the SLS Project Designer. Response time of the Warning 1 andWarning 2 will be same as the OSSD response time. Table 3-4 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. (Refer to chapter 4). User must perform risk assessment before
configuring the response time. Addition of maximum 1 cycle (30ms) has to be taken into account for the areaswitching.

3.18 Laser Off Mode
Laser off mode is a function to completely stop the laser emission in the measurement region in order toprevent the interference to the surrounding equipment.
When this mode is enabled, Area1 is automatically assigned for laser off function. During the operation,
SE2L will stop the laser emission and switch the OSSD and the Warning output to OFF state whenever thearea is switched to Area1.

3.19 Scan Skip Function
Scan skip is a function to stop the laser emission for a specified number of scan cycles in themeasurement region. The function may reduce the interference to the surrounding equipment.
When this function is enabled by specifying the skip count, SE2L will operate by skipping the scan for
the number of cycles. During the skipping cycle the laser is switched off in the measurement region.
Configurable value for skip cycle is 0 - 3 count. Response time of SE2L for the different settings is shown in
Table 3-7.

4. Application examples of SE2L
The section describes some application examples of SE2L and safety distance calculation in therespective application. When using the SE2L as protective equipment, guidelines below should be taken into
account.

Hazard should be identified and risk assessment should be carried out.
SE2L should not be used for finger protection.
Working environment should be within the specification of SE2L.
Safety distance must be determined in accordance to ISO 13855 and IEC 61496-3.
Operating the SE2L beyond its specification could lead to critical injury and death.

4.1 Access protection (Horizontal application Stationary Protection zone 1)
In this kind of application, SE2L is mounted horizontally to protect the hazardous area (Figure 4-1).
The protection zone is configured around the hazardous area to prevent the entry of human beings or object.
Warning zone 1 and Warning zone 2 are configured surrounding the protection zone. Warning zones are used
for alerting human beings or object from approaching the protection zone and preventing unnecessary stopsof the protected machine. Any objects or human beings detected in the protection zone will cause the OSSD
signal to switch to OFF-state from ON-state. Any objects and/or human beings detected in the warning zones
will cause the warning signal to switch from ON-state to OFF-state. The safety distance for this applicationis shown in figure 4-2 and 4-3.

where:
S = Safety distance (mm)K = Approach speed 1600 (mm/s)
Tm = Maximum stopping/run-down time of the machine or system (s)Ts = Response time of SE2L (s)C = 1200-0.4×H≧850
H = the height at which the protective field is mounted (mm)1000≧H≧15× (d−50)

d = Minimum detectable object width (mm)Zs = SE2L tolerance distance (mm)

User must ensure the distance between the hazard zone edge and origin of theprotection zone “a” must be less than the minimum detectable width. In application
where the value of “a” is greater than the minimum detectable width, additional
protective measures should be taken to prevent penetration through this unprotected
area.
SE2L should not be mounted higher than 300 mm to prevent the possibility of
crawling beneath the detection plane.
For applications which require the SE2L to be mounted higher than 300 mm,
additional measures should be taken to prevent intrusion beneath the detection plane.
If SE2L is mounted in a public area, the height of the detection plane should be
reduced to 200 mm or to the height required by regulations of the local authority.

It is recommended to mark the floor of the protection zone.
Distance tolerance should be taken into account when configuring the safety distance.
Additional tolerance should be applied when SE2L is used in the presence of highreflective background.
User should ensure that boundary or protective measures used are not included inside theprotected zone. They will be detected as obstacles causing the OSSD to remain in
OFF-state.
User should ensure the gap of 100mm between the protection zone and the distance of
the wall “b” to prevent the detection by the sensor.

4.2 Access protection (Stationary Horizontal application with Dual
Protection zone)
In this kind of application, SE2L is mounted horizontally to simultaneously protect two hazardous areas(Figure 4-4). Protection zones are configured around the hazardous area to prevent the entry of humanbeings or object. Warning zone cannot be configuration in dual protection mode. Any objects or humanbeings detected in the protection zones will switch the respective OSSD signal to OFF state from ON-state.
In this configuration it is possible to protect two equipment using a single SE2L.
The safety distance for this application is shown in figure 4-1.

Protection zone 2
Figure 4-4 Example Horizontal application of access protection (Dual protection zone)

4.3 Access protection (Vertical application- whole body detection)
SE2L can be used as a protective shield by mounting it vertically (Figure 4-5). Application shown in the
figure is generally used in preventing the access to hazardous area. When an object or human enter thepassage, OSSD signal will switch from ON-state to OFF-state.
In this configuration, SE2L detects objects or human beings in vertical plane. It is not possible to detect anobject or human being at the front or back side of the detection plane. Therefore, caution should be taken
while setting the distance between the detection plane and hazardous area. Configure the shortest responsetime of SE2L not exceeding 90ms. Always use reference monitoring function in such applications to detectthe displacement of fences and SE2L which may expose the hazardous area. OSSD signal will switch to OFF
state when the position of reference is changed. The safety distance for this application is shown in figure
4-6 and 4-7.

If the value of “a” is greater than minimum detectable
width, additional protective measures should be taken to prevent the penetration
through this unprotected zone.

In the access protection application where the angle of approach exceeds ±30º,“Reference monitoring” function should be used with 100mm tolerance range for thereference zone. Response time should be configured below 90ms in such application.



Reference segments should be configured on each sides of reference boundary.
SE2L should be mounted in such a way that accessibility towards hazardous point is
impossible. Use additional protective measures if necessary.



Tolerance should be taken in account when configuring the reference segments.

4.4 Access protection (Vertical application Stationary)Figure 4-8 shows an example to prevent the access when part of the body is approached near thehazardous area. If objects or part of body enters such area, OSSD signal switches to OFF state from ON-state.
SE2L detects an object or human being in vertical plane in such configuration. It is not possible to detect anobject or human being at the front or back side of the detection plane. Therefore, caution should be taken
while deciding the distance between approaching point and hazardous area. The width of protection zone
should be sufficient to protect the hazardous area. Always use reference monitor function in suchapplications to detect the displacement of fences and SE2L which may expose the hazardous area. OSSD
signal will switch to OFF state when the position of reference is changed. The safety distance for thisapplication is shown in figure 4-8 and 4-9. Refer to section 7.15 for configuring the protection zone.

4.5 Area protection (Horizontal application Mobile) Fixed area
SE2L can be used for mobile applications such as AGV (Figure 4-10). It is installed on an AGV todetect objects while travelling along a fixed route. Warning signals in such application can be used for
reducing the speed and stop the AGV. A maximum 32 area sets (128 area sets when encoder input function isused) can be used to match the travel route of the AGV. Confirm the time and distance required for the AGV
to stop completely when configuring the protection and warning zones. The safety distance for thisapplication is shown in figure 4-11 and 4-12.

When using the SE2L on an AGV, user should confirm the time and distance required for the AGV tostop completely as it will move forward during the response time of SE2L. It is important to note that
distance required to stop is not proportional to the speed, but proportional to the square of the speed.
Further, sufficient ground clearance should be provided to prevent injuries, such as, hitting the toes.
Figure 4-13 shows the relationship between ground clearance h and Zg.

SE2L should not be mounted higher than 200mm to prevent the possibility of crawling
beneath the detection plane.
Detection plane should not be inclined as this could lead to the failure of SE2L todetect an object with a diameter of 200mm.

User should ensure that boundary or protective measures used are not inside theconfigured protected zone. It will be detected as obstacles causing the OSSD toremain in OFF-state.

Cautions during the installation of SE2L are explained in this chapter.

5.1 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.
Incandescent lightFluorescent lightStroboscopic lightFlashing beacon

SunlightInfrared light sources
In case the light source cannot be avoided during the operation, SE2L should be installed with the lightsource located at ±5 degrees or more from the detection plane to prevent the interference (Figure 5-1).

Figure 5-1 Installation to avoid light interferenceUser should perform risk assessment for light interference in the working
environment before the installation.



Avoid direct light such as stroboscopic, flashing beacon, fluorescent.

Failing to comply with the above could lead to critical injury or death.

User should verify detection capability before actual operation.

SE2L User’s Manual (SE9Z-B1865)66

5.2 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 themutual interference.
a) Changing the height of installation
Install at different heights to separate the mutual detection plane by 5 degrees or more.

Figure 5-2 Opposite facing installation

Figure 5-3 Parallel installation

SE2L User’s Manual (SE9Z-B1865)
67b) Changing the angle of installation
Change the installation angle of SE2L by 5 degrees or more from the mutual detection plane.

Figure 5-4 Opposite facing installation

Figure 5-5 Parallel installationC) Adding a shield between SE2Ls
Add a shield between SE2Ls such that laser beam of one unit cannot reach the other to avoid the possible
mutual interference.

Figure 5-6 Opposite facing installation

SE2L User’s Manual (SE9Z-B1865)
68

Figure 5-7 Parallel installation



Shielding material should be opaque.

5.3 High reflective background
Measured value will be longer than the actual distance of the object due to high reflective backgroundleading to wrong OSSD output. 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 5-8). Refer to SE2L’s specification for the required distance tolerance.

100+200mm* Additional distance : Required additional distance when operating SE2L under high reflective background

Specification of Distance tolerance is “+100mm”.

Figure 5-8 Additional distance in high reflective backgroundSE2L User’s Manual (SE9Z-B1865)
69



Measured value will be longer than actual distance of the object if the
background is highly reflective. Additional distance should be included when
configuring the protection zone.

High reflective background (Ex.: Mirror, corner cube reflector, reflective safety
jacket, road reflector) should be avoided. Reflectance caused by these materials
could lead to false detection in the protection zone.

Verify the configured areas before actual operation.

Failing to comply with the above could lead to critical injury or death.

5.4 Limited detection capability zone
The limited detection capability zone is defined as a region between the optical window and start of thedetection zone. The limited detection capability zone of the SE2L is 90mm from the origin of SE2L (Figure5-9). Presence of object with low reflectance may not be detected in this zone.

Figure 5-9 Limited detection capability zoneUser should perform risk assessment for possibility of object penetration into
the limited detection capability zone.

6. Wiring
This chapter describes safety precaution when wiring the SE2L. To connect SE2L-H05LPC, use an
Optional Connector cable (SE9Z-HS2-C***).

6.1 Precautions
During electric wiring make sure that all devices are disconnected from power supply. Switch off all thepower supply during wiring. Confirm that power supply is OFF.

6.2 Power supply
Make sure that power supply is within the range of 24V DC ±10%. For battery operation, power supply
should be within the range of 24V DC -30% / +20%. SE2L could be damaged if rated output voltage exceeds
this range.

For safety, switch OFF the power supply during electrical wiring.

6.3 Wire color and function

● Avoid touching the internal parts of SE2L as it may contaminate them decreasing thedetection capability.
Caution ● Afterreplacing the optical window it is necessary to apply the adjustment SE2L isready to use only after completing the adjustment.
● Use the [Optical Window Adjuster] application to only calibrate a newly replaced
optical window. Using it to recalibrate an old optical window may reduce the detection
capability of the device.

8.6.2 Adjustment of the optical window
During the operation SE2L constantly monitors the transmittance of optical window. When it decreases
due to contamination SE2L reports an error. Therefore, it is necessary to measure the initial transmittance ofthe new optical window and save it into the device. Contamination should not be present while performing
this adjustment.

<Adjustment steps>a) Use adjustment software “Optical Window Adjuster” included in the CD. Create a local folder and savethe application into it. Log file generated during the process (format “serial_number_time.log”) and theadjustment data (format “serial_number_time.csv”) are saved in the same folder where the application issaved. Retain these files for reference and troubleshooting.
b) Supply the power to SE2L and connect with the PC through USB cable.
c) Start Optical Window Adjuster. Window as shown in figure 8-2 will appear.

Figure 8-2 Optical Window Adjusterd) Click connect button after SE2L is detected and COM port number is displayed. Click search, if COM
port number is not displayed.
e) Click Start Adjustment button when it is enabled.
f) When application is ready, password window will appear. Enter the password of the device and click“OK” button. SE2L will restart once and start the calibration. It will approximately 6 minutes tocomplete the calibration of 8 contamination channels. 7-segment display on SE2L will show the code“CE” durting the process.

Figure 8-4 Error displayg) When adjustment is complete, dialog box as shown in Figure 8-3 will appear. Click the OK button andthen click disconnect button (Figure 8-2). Remove the USB cable. SE2L will switch to normal operation.
Retry the adjustment after checking the optical window and USB connection if an error dialog as shown in
Figure 8-4 is displayed. If adjustment fails even after repeated trial contact the nearest distributor or sales
representative for support. Send the log file and calibration data file for investigating the cause of failure
in such case.

8.7 Check the firmware version
Check the firmware version of the target SE2L by the following methods:a) Supply the power to the SE2L. Connect USB cable of the SE2L to the computer.
