Safety precautions

Danger
Please 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. Optical radiations 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 by monitoring 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 the functionality 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 the operator 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 the local safety requirements, standards, rules and regulations, laws of respective nations, states or districts when the 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 by customers or third parties. IDEC cannot take responsibilities for any loss from the misuse except for the responsibilities governed by low.
   ● 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 the stated 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 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 will be degraded. Injury may also be caused.

2. Operating environment
   Danger
   ● Make sure that SE2Lʼs operating environment is within the stated specification (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 such environments may decrease the detection capacity of SE2L.
   ● This product is for indoor use only.

3. Installation
   Danger
   ● Install the SE2L on a firm surface or structures to avoid displacement of the sensor.
   ● The SE2L should be firmly mounted using screws. Shock and vibration should not loosen the mounting. SE2L will not operate properly 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 by placing 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 the whole 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 space for maintenance.
   ● Do not add any protective materials such as glass, transparent cover etc in front of the optical window. This would lead to loss of detection capability of the SE2L.
   ● Minimum detectable width varies with the distance.

4. Wiring
   Danger
   ● Switch OFF all the power supply during wiring.
   ● If the source of the power supply is taken from a converter, please ensure the power supply fulfils the following requirements:
   a) A rated output voltage of 24VDC ±10%(SELV circuit, Over voltage Category II)
   b) Reinforced insulation or double insulation for the primary and secondary circuit
   c) Holding time of the output should be above 20ms
   d) The power supply must comply with the requirements of electrical safety and electromagnetic compatibility (EMC) regulations of the respective country, states and district.
   ● All the input/output signal cables should be installed away from machines 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 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.

5. Configuration
   Danger
   ● Configuration of safety functions are password protected. Only authorized personnel or operator with password are allowed for configuration.
   ● SE2L will not operate without an initial configuration.
   ● Pre-operation test must 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. Operator can use the report generating function in the SE2L Project Designer.

6. Test and maintenance
   Danger
   ● User must perform the following tests and maintenance by referring to the checklists in this manual.
   a) Pre-operation inspection
   b) Operation inspection
   c) Daily inspection
   d) Periodical inspection
   *The checklists in this document are provided as basic guidelines while performing the test and maintenance. User must perform additional inspection and maintenance tasks deemed necessary for the respective application.
   ● Stop the machine and stop using the SE2L if faults are detected during these tests.
   ● Clean the optical window when it gets contaminated. If the optical window is damaged it should be replaced by a new one.

SE2L components

Functions

SE2L’s function can be configure using the SLS Project Designer.

1. 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.
   a) Protection zone, Warning zone 1 and Warning zone 2
   b) 2 Protection zones (Dual Protection)
   In dual protection mode, two protection areas can be configured therefore two machines can be protected by one unit of SE2L. Protection and warning zones can be configured by using SLS Project Designer. ● 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 from ON-state 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
   1 shows the examples of protection zone configured using manual mode and teaching mode respectively. User must configure these zones accordingly to ensure hazardous area is completely protected.
   ● Warning zone
   Warning zones are non-safety zones and are connected to Warning 1 and Warning 2 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.

2. 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 the signal periodically. 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 fulfil the required safety level. If OSSD3 and OSSD4 are used they must be connected in the same manner.

3. Interlock function
   Interlock is a function to prevent automatic restart of the OSSD signal switching from OFF-state to ON-state. OSSD1/2,RES_REQ 1 and RESET 1 are for protection zone 1; OSSD3/4,RES_REQ 2 and RESET 2 are for protection zone 2 when setting the sensor by SLS Project Designer. We use OSSD, RES_REQ and RESET in the rest of 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 SE2L is in the lockout state due to error, OSSDs will remain in OFF-state even if the interlock function is disabled.
   ● Manual restart
   When interlock function is set to manual restart mode, even if the detected obstacles or system error is removed, OSSD signals will remain in OFF-state. An external reset input signal is required to release the interlock which allows the SE2L to switch to normal operation. RESREQ signal will be switched to ON state when obstacles disappear from protection zone. SE2L will resume normal operation only after confirming the reset signal (RESET). The duration of the reset signal should be more than 500ms. After RES REQ 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 remain in 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 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 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 from the controlled machine or automated guided 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 be always inverse of the OSSD signal. EDM input signal ON/OFF delay is configurable to match 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 SLS project designer. When muting inputs fulfil the muting start conditions, SE2L will suspend the safety function for the muting zone within 60 ms.
   ● 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 time interval. 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 muting time.
   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 another area.
   ● 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 (RESET1/2) are switched in a sequence.

6. Reference monitoring function
   Reference monitoring is a function to monitor the displacement of the SE2L 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 is detected, and also if the distance between SE2L and the reference structure changes. This function is compulsory for vertical applications. Fig-2. Front view of the access detection using reference monitor function
   ※This function can be also used in area protection applications. Refer to User’s Manual for the detail.

7. 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. This function 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) whereas it can only switch to specified areas if area sequence is enabled. (Figure 4).Area sequence function is recommended for control systems where switching area sequences can be configured.
   Fig-3. Operation without area sequence Fig-4. Operation with area sequence

8. Response time
   Response times of OSSD signal, OFF response time (Default 60 ms) and ON response time (Default 270 ms) are configurable individually for each area using the SE2L 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 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. 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** OFF (ON->OFF)| Response time (ms)
   ---|---
   60| 90| 120| 150| 180| 210| 240| 270
   300| 330| 360| 390| 420| 450| 480| 510
   ON (OFF->ON)| Response time (ms)**
   | | | | | | | 270
   300| 330| 360| 390| 420| 450| 480| 510

9. 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 2 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 and inverted signal. For example, it is necessary to provide both input signal INA and inverse IN A signal to switch the area. Error will occur if INA 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 to provide stable input signals to SE2L. 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 through the speed monitoring of increment encoder signal connected to SE2L.
   Table-2. Input combination for area switching** Mode| Protection| Max internal input| Max Area| Max encoder area**

10. Increment 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 by encoder’s phase A and phase B signal that have the phase difference of 90°. Speed and rotating direction of both encoders are constantly monitored to detect abnormal travel and stop the AGV.

11. Ethernet communication
    Measurement data of SE2L can be obtained from the Ethernet communication. For the communication specification of SE2L, contact Water proof Ethernet connector is located at the back of SE2L. contact the nearest distributor or sales representative.
    To connect sensor with PC use an Optional Ethernet cable (SE9Z-HS2-XCD13).
    ● Ethernet Setting
    a) Default setting
    Factory default value is shown below.
    IP address: 192.168.0.10
    Default gateway: 192.168.0.254
    Subnet mask: 255.255.255.0
    Port number: 10940
    b) Changing the IP address
    IP address can be changed by using SLS project Designer. Refer to section 7.13 and 7.9.1 for details, refer to the userʼs manual.

12. Function to configure SE2L by SD card
    Configuration generated by SLS Project Designer can be saved in a SD card. It is possible to transfer the setting directly from the SD Card to SE2L without connecting to a PC.The type of SD card should be Micro SD card when this function is used.
    Create a project file with set the serial number and password of the SE2L and save it on the SD card using SLS Project Designer. When the SD card is inserted to the specified SE2L, settings are automatically transferred. Setting will not be transferred to the unspecified SE2L.

13. Master-Slave Function
    Maximum 4 units of SE2L 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.

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.

1. Incandescent light
2. Fluorescent light
3. Stroboscopic light
4. Flashing beacon
5. Sunlight
6. Infrared light sources

In case the light source cannot be avoided during the operation, SE2L should be installed with the light source located at ±5 degrees or more from the detection plane to prevent the interference (Figure 6).

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 the mutual interference.

1. Changing the height of installation
   Install at different heights to separate the mutual detection plane by 5 degrees or more.

2. Changing the angle of installation
   Change the installation angle of SE2L by 5 degrees or more from the mutual detection plane.

3. 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.

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 200 mm is necessary while configuring the protection and warning zones (Figure 13).

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 SE2L is 90 mm from the origin of SE2L (Figure 14). Presence of object with low reflectance may not be detected in this zone.

Wiring

Wiring example and cautions are shown bellow.

1. Precautions
   a) During electric wiring make sure that all devices are disconnected from power supply. Switch off all the power supply during wiring. Confirm that power supply is OFF.
   b) Do not exceed cable length stated in the specification of SE2L.

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