  • Page 17: Chapter 1. General Information

    CHAPTER 1 GENERAL INFORMATION GENERAL DESCRIPTION The Laser Sentinel is an electro-sensitive protective equipment (ESPE). It employs active opto-electronic protective devices responsive to the diffuse reflection of a radiation (AOPDDRs), according to the definition and requirements of international safety stan- dard IEC 61496-3.

  • Page 18: Reference Standards And Regulations

    GENERAL INFORMATION REFERENCE STANDARDS AND REGULATIONS The safety laser scanner is a safety system used as an accident-prevention protection device and is manufactured in accordance with the international Standards in force for safety, in particular: STANDARD DESCRIPTION Harmonisation of the laws of the Member States 2014/30/EU EMC Directive relating to electromagnetic compatibility.

  • Page 19: Package Contents

    PACKAGE CONTENTS Package contains the following objects: • Laser Sentinel • Quick Reference Guide of Laser Sentinel • Periodical checklist and maintenance schedule BASIC INFORMATION The user can follow the indications related to typical application configurations that facilitate the device programming. Two types of configuration have been developed on DL Sentinel so far: 1.

  • Page 20: Chapter 2 Typical Applications

    This area cannot be used for safety pur- poses. The possible applications to employ the Laser Sentinel are: Horizontal (to monitor an area that must be crossed in order to reach the hazardous point) and Vertical (to moni- tor an access point).

  • Page 21: Horizontal Application Configuration

    The device uses a horizontal protective field (the red area in the figures) to detect the presence of an object or a person. The Laser Sentinel will scan the environment surrounding the hazardous point to detect approaching objects or people. If someone is detected in the safety zone (with a given detection capability), the safety laser scanner switches all safety outputs to the OFF state through the safety fieldbus protocol.

  • Page 22: Vertical Application Configuration

    TYPICAL APPLICATIONS VERTICAL APPLICATION CONFIGURATION Figure 3 - Vertical application The device uses a vertical protective field (the red area in the figure) to detect someone passing through it. In this example the only way to reach the hazardous point is to pass through an open- ing: all other access points to the machine are protected by some physical barrier or other sensors.

  • Page 23: Chapter 3. Safety Information

    (e.g. motor power supplies, inverters, etc.). • Do not connect any of the Laser Sentinel inputs to DC power sources outside of the declared range or to any AC power source, to avoid the risk of electric shock. INSTRUCTION MANUAL...
  • Page 24 SAFETY INFORMATION • Every access to the configuration tools must be allowed only to restricted and highly qualified personnel. The configuration upload through the GUI is only allowed by password. • Periodically monitor the optical window during the entire product life-cycle check- ing for any damage, scratches or dirt spots.

  • Page 25: Chapter 4. Installation

    CHAPTER 4 INSTALLATION INSTALLATION PRECAUTIONS Make sure that the protection level assured by the Laser Sentinel is com- patible with the danger level of the working machine, according to EN ISO 13849-1 or EN 62061. WARNING • It must not be possible for operators to approach the dangerous zone without being detected by the Laser Sentinel.

  • Page 28: Light Interference

    INSTALLATION Light Interference Reflecting surfaces located near the safety device may cause passive reflections. These can affect the detection of an object inside the safety zone. The passive light sources can be an incandescent lamp, sunlight, a fluorescent light, a strobe light or other infra- red light sources (e.g.

  • Page 29: Highly Reflecting Background

    If there is a highly reflecting background within 3 meters of the safety zone boundary, e.g. a metallic glossy surface, the Laser Sentinel might fail to recognize the exact dis- tance of the detected object because of an increase in the measure error.

  • Page 30: Zone With Limited Detection Capability

    INSTALLATION ZONE WITH LIMITED DETECTION CAPABILITY Laser Sentinel may not properly detect an object located at a distance of 10 cm or less from the safety zone origin. This zone is called “zone with limited detection capability.” In this circumstance, a risk assessment is recommended taking into account the possi- bility that an object can cross a zone with limited detection capability.

  • Page 31: Device Positioning And Minimum Distance Calculations

    DEVICE POSITIONING AND MINIMUM DISTANCE CALCULATIONS The Laser Sentinel must be carefully positioned to fulfill its safety function. In fact, access to the dangerous area must only be possible by passing through the safety zone. Under standard operating conditions, starting the machine must not be possible while operators are inside the safety area.

  • Page 32: Minimum Safety Distance Calculations For Horizontal Applications

    INSTALLATION Minimum Safety Distance Calculations for Horizontal Applications The Minimum Safety Distance cannot exceed the nominal maximum limit of the Safety Zone for the scanner (5.5 m). NOTE If the device is mounted with a detection angle of less than 30° with respect to the hori- zontal plane (floor), the application is considered horizontal (parallel approach).
  • Page 33 Example of additional distance due to Height: With a given machine stopping time of 0.4 s and a selected Laser Sentinel Response Time of 94 ms, detection capability = 70 mm and without any ambient interference: S = [(1600 mm/s*(0.094 s+0.4 s)] + [(1200 mm –...
  • Page 34 INSTALLATION Example of additional distance due to Ambient Interference: From the previous example with a height of 300 mm, but in the presence of high reflec- tive backgrounds and/or direct bright light: Minimum safety distance S - C = [(1600 mm/s*(0.094 s + 0.4 s)] + (1080 mm + 100 mm) = 1970.4 AMBIENT INTERF = 200 mm for “dust filter level”...

  • Page 36 Figure 7 - Access protection Figure 7 shows the use of Laser Sentinel as a whole-body safety device where the refer- ence boundary is the edge of the safeguarded aperture. In this application we have to take into account the tolerance zone of the safety laser scanner and the dimensions of a possible unprotected zone due to the physical installation (a), taking additional precau- tions by another means, for example additional mechanical protection.

  • Page 37: Minimum Safety Distance Calculations For Mobile Applications

    DEVICE POSITIONING AND MINIMUM DISTANCE CALCULATIONS Minimum Safety Distance Calculations for Mobile Applications Laser Sentinel can be installed on a mobile machine, e.g. an AGV, in order to constantly monitor the absence of persons along the driving direction of the vehicle, detecting their presence in the safety zone parallel to the direction of approach.

  • Page 39 DEVICE POSITIONING AND MINIMUM DISTANCE CALCULATIONS T = response time of the Laser Sentinel, as set by the user according to the number of scans (see " " on page 77 Also when calculating the minimum width of the safety zone, increases must be taken into account to compensate for possible environmental interference and the increase due to the lack of aperture between the AGV and the floor.

  • Page 40: Unprotected Zone

    INSTALLATION UNPROTECTED ZONE The unprotected zone (a) must be small enough to ensure that a person cannot approach the danger zone or stay between the danger zone and the safety zone without being detected. This can require additional mechanical protection. SAFETY ZONE MACHINERY Figure 9 - Safety Distance Example (Top View)

  • Page 41: Distance To Wall

    DISTANCE TO WALL DISTANCE TO WALL The Safety Zone must maintain a tolerance of at least 40 mm from any wall or fixed object (a and b in the image above). This value is generally enough to guarantee normal operation, however accord- NOTE ing to the real reflectance characteristics of the wall, a higher value may be necessary.

  • Page 44: Checks After First Installation

    To test the detection capability of the device(s), the user can use a suitable test piece, e.g. an optically dark, opaque cylinder. The effective diameter should match the configured resolution. Datasensing suggests adopting the following proce- dure: Place the test piece on several points at the edges of the safety area. The safety laser scanner must detect the test piece at each position and go to STOP.

  • Page 81: Muting

    MUTING MUTING The Muting feature allows the automatic deactivation of the safety status overall (Total Muting) or part (Partial Muting) of the safety area. This feature is particularly suitable when an object, but not a person, must pass through the dangerous area. This allows carrying out definite cyclical operations without blocking a working machine.

  • Page 82: Muting Signaling Devices

    FUNCTIONS Carefully select the configuration, because a wrong one can cause the incorrect functioning of the Muting feature and a reduction of the safety level. To correctly use the Muting feature, please refer to the relevant ref- WARNING erence standard. The Muting sensors must be placed so that during the activation of the Muting feature it is not possible for a person to pass through the desired zone.

    APPENDIX D GLOSSARY NAME DESCRIPTION Active opto-electronic A device whose sensing function is performed by optoelectronic protective device emitting and receiving elements. These detect the diffuse reflec- responsive to diffuse tion of optical radiations generated within the device by an reflection (AOPDDR) object located in a detection zone (specified in two dimensions).
  • Page 138 A High Dust Filter Level is used in dirty environments to filter (ignore) detection of airborne particles from being confused with objects to detect. The Laser Sentinel is less sensitive to Dust Filtering dust and therefore avoids shutting down the machinery unnec- essarily.
  • Page 139 This number depends on the parameter set in the configuration. State in which the output circuit is interrupted and does not per- mit the flow of current. When Laser Sentinel detects an object in OFF-state the safety zone it switches to this state which causes the dan- gerous machinery to stop working.
  • Page 140 This is the area around the Safety Zone; the device can signal a Warning Zone warning lamp or siren if it detects an object in this area. This is an area (zone) that is controlled by the Laser Sentinel. Zone Set More than one zone can be defined and therefore switched (set) by a combination of inputs.
