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 reflected back from an object within the range. 

**==> picture [201 x 81] intentionally omitted <==**

**----- Start of picture text -----**<br>
Laser Emitted pulse laser<br>Object<br>Received pulse laser<br>Photodiode<br>Time difference<br>Distance to object (L)<br>**----- End of picture text -----**<br>


The distance can be calculated as follows: 

= −[1] × c × T L 2 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 configured. A software SLS Project Designer supplied with the SE2L is used to configure the protection and warning zones, providing excellent user interface. 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. 

Protection zone: The area obtained by risk assessment and calculation of safety distance Warning zone: The area to send alarms which can be set according to the application 

## Area Switching 

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. 

Maximum number of patterns 

|Mode|Protection|Max.<br>Internal<br>Input|Max.<br>Area|Max.<br>Encoder<br>Area|
|---|---|---|---|---|
|Standard|1|5|32|−|
||2|5|32|−|
|EDN|1|4|16|−|
||2|4|16|−|
|MUTING/EDM|1|2|4|−|
||2|1|2|−|
|Encoder(Note 1)|1|2|3|32(Note 2)|



Note 1: Dual protection and muting function modes cannot be used when encoder input mode is selected. 

Note 2: Among the four input patterns, at least one pattern must be used for encoder input. Other three 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 32 sets of area.

## SE2L Safety Laser Scanner 

## Response Time 

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 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 configurable response time is shown in the table below. Be sure to add the time taken to switch areas (30 ms).

## Safety Distance 

Warning zones 1 and 2 are set around the protection zone to send alarms to prevent humans or objects from entering the hazardous area and stopping the machine. By detecting humans or objects in the protection zone, the OSSD signal switches from ON to OFF. Also, when humans or objects are detected in the warning zone, WARNING signal switches from ON to OFF.

## Access protection 

In this application, the SE2L is horizontally installed to protect the hazardous area. The protection zone is set around the hazardous area to prevent humans or objects from entering the hazardous area. Warning zones 1 and 2 are configured to surround the protection zone. 

## Protection zone 1 application (horizontal, stationary installation) 

## Calculation 

S = (K × (Tm + Ts) + C + Zs 

- S  = Safety distance (mm) K = Human approach speed 1,600 (mm/s) 

- Tm = Maximum stop speed of machine or system (s) 

- Ts = Response time of SE2L (s) 

- C = 1200 − 0.4 × H ≥ 850 

H = height from the floor to the sensing plane (mm) 1000 ≥ H ≥ 15 × (d − 50) 

   - d = Minimum sensing width of object (mm) 

- Zs = Additional safety distance of SE2L (mm)

## SE2L Safety Laser Scanner 

## Highly Reflective Background 

## Wiring 

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

The table below shows the functions of each wire. Use of a shielded wire is recommended.

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** 

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

- x SE2L is a AOPDDR (Active Optoelectronic Protective Device responsive to Diffuse Reflection) 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 modification or disassembly of the SE2L. 

- x The operator must be a person qualified 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 find 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. 

## Operating Environment 

- x Make sure that the operating environment is within the range of the specifications (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. 

- 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.

## **Safety Precautions** 

## Wiring 

- x Be sure to turn off all power before wiring. 

- x 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 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. 

## 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. 

- 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 configuring the safety function. Only an administrator or operator should be able to set safety functions. 

- x SE2L will not operate without initial configuration. 

- x Perform test operation and check the configuration 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 configuration. SLS Configurator report function is available. For details, see the User's Manual.
