  • Page 19: 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 20: 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 22: 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 23: 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), a stopping signal is sent to the machine by the device.

  • Page 24: 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 25: Applications With Master And Slave Connection

    The Laser Sentinel can effectively solve this situation: irrespective of the use in horizon- tal or vertical position, up to 4 Laser Sentinel units can be easily connected to each other through Ethernet-based safe communication bus, working as a single system.

  • Page 30: 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 31: High Reflecting Background

    If there is a high 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 distance of the detected object because of an increase in the measure error.

  • Page 32: 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 33: 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 34: 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 70: Laser Sentinel Setup And Configuration

    LASER SENTINEL SETUP AND CONFIGURATION This chapter is dedicated to the Laser Sentinel setup and configuration using the DLSen- tinel software. The aim of this chapter is to guide the user through all the fundamental procedures of configuring the device.

  • Page 71: Program Installation

    When the installation is complete, the DLSentinel entry is created in the Start > All Pro- grams menu under “Datalogic” along with a desktop icon. Double-click the desktop icon to run it. A dedicated computer running DLSentinel must be connected to a Safety Laser Scanner through the Ethernet port to perform the configuration and monitoring features.

  • Page 72: Functions

    Laser Sentinel and no input signals are needed to manage it. Laser Sentinel allows the user to set up a given number of Zone Sets: a maximum of six Zone Sets for the Stand Alone model, a maximum of three Zone Sets for the 8-pole Mas- ter model, a maximum of ten Zone Sets for the 12-pole Master model, and a maximum of seventy Zone Sets for the 17+8 pole Master model.

  • Page 73: Zone Set Switching

    ZONE SETTING CONFIGURATION AND SELECTION • Define the input combinations. • Make sure that the system, which generates the input combination, can dynami- cally switch the state of the inputs within the required time and without passing through intermediate invalid combination states. It is possible to insert a delay up to 100 ms for the input switching (INPUT DELAY) to guarantee the correct timing during the Area Switching.
  • Page 74 NOTE 3. Assign each Area Switch to an available Input Signal Pin. The Stand Alone Laser Sentinel has three configurable Inputs. If the user chooses to employ from three to six Zone Sets there will be no available I/ O for other functions. For example, it will not be possible to employ the NOTE Manual Restart or send an electrical warning signal.
  • Page 75 ZONE SETTING CONFIGURATION AND SELECTION The following figure shows the possible input combinations in case of six Zone Sets. Figure 3 - Six Zone Sets (Stand Alone model) M12 12-pole Master model: 10 Zone Sets The M12 12-pole Master model can monitor up to 10 different areas. To do that, the user must configure the input combination by selecting the signal “Area Switch”, set five inputs as Area Switch and then create a sequence of univocal combinations as described above.
  • Page 76 FUNCTIONS M12 17+8 pole Master model: 70 Zone Sets The M12 17+8 pole Master model can monitor up to 70 different areas. To do that: 1. Set the Zone Set No. to “70”. 70 Zone Sets will appear with their relative Area Switch combinations.

  • Page 77: Detection Capability Setting

    The detection capability is the ability to detect an object of given dimensions within the detection zone. In particular, for the Laser Sentinel, the test piece taken as reference is an opaque cylinder with at least 300mm height and the diameter equal to the detection capability measured in millimeters.

  • Page 78: Automatic And Manual Restart

    FUNCTIONS AUTOMATIC AND MANUAL RESTART If Laser Sentinel detects an opaque object, the OSSD outputs switch to the OFF-status (the opening of the safety contacts). The restart mode allows the safety laser scanner to return to a normal operating condition.
  • Page 79 AUTOMATIC AND MANUAL RESTART The Manual Restart input must be connected to a 24 Vdc normally open contact. NOTE If an object is not removed from the Safety zone and the operator attempts to restart the device, by pressing the button for more than 500 ms, the Safety Laser Scanner remains in Interlock OFF status.

  • Page 80: Response Time And Scan Cycle Setting

    The response time of the Laser Sentinel is the time from when an object enters the safety zone to when the OSSD goes to the OFF-status due to the detection of the object. The Laser Sentinel scans cyclically with a constant speed and it employs 30 ms to do one complete rotation.

  • Page 81: Reference Points Monitoring Settings

    Example application for movable structure protection When the reference points (minimum 3), are set on the position of a movable structure, such as a door, the OSSD goes to the OFF-state if the Laser Sentinel detects a change in the position of the door.
  • Page 82 GUI gives a warning message indicating that this configuration is not valid for whole body protection applications (greater than 1.6 m/s). To safely apply the Laser Sentinel in applications with normal approach (i.e. when the monitored plane is vertical), refer to IEC 61496-3 Annex A.12.

  • Page 83: Safety Outputs (Ossds)

    SAFETY OUTPUTS (OSSDS) SAFETY OUTPUTS (OSSDs) The OSSD (Output Signal Switching Device) is a safety output for safety-related parts of a machine control system. When the device detects an object or a person in the Safety zone, the OSSD goes to the OFF-status (the machine stops). The device generates signals to monitor the OSSD status and these periodically force the OSSD into a temporary OFF condition if the OSSD is ON (when there is no object detected in the Safety zone).

  • Page 84: Ossd Test

    FUNCTIONS OSSD 1/1 must be paired with OSSD 1/2. OSSD 2/1 must be paired with OSSD 2/2. OSSD 3/1 must be paired with OSSD 3/2. NOTE OSSD test The following diagram illustrates the different times needed for OSSD tests. Figure 13 - OSSD test Where: s T1 (Test pulse width) = 115...

  • Page 85: Muting

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

  • Page 86: Muting Enable

    FUNCTIONS Muting Enable When the Muting feature is implemented (through two Muting inputs), a third input can be used to dynamically control whether Muting will be performed or not. The third input is labeled MUTING ENABLE and works as follows: prior to a valid Muting sequence on the Muting inputs, if the MUTING ENABLE signal is at a high level, the Muting feature is enabled, and Muting will be performed;...
  • Page 87 MUTING The sensors A1/A2 are connected to Muting 1 input and the sensors B1/B2 are con- nected to Muting 2 input. The user has to mount the sensors A1/A2 or B1/B2 at a “D” distance. “D” depends on the package length (L): D < L; “d1” is the maximum dis- tance between the Muting sensors (this distance depends on the package speed (V): d1max[cm] = V[m/s] * T12[s] * 100);...

  • Page 88: Unidirectional Muting

    FUNCTIONS Unidirectional Muting In Unidirectional type operation, the device enters in Muting if the Muting 2 input goes high after the rising of Muting 1 (or vice versa). The user can set the value of Max Mut- ing Inputs Delay between Muting 1 and Muting 2 from a minimum of 1 sec to a maxi- mum of 16 sec.

  • Page 94: Edm

    FUNCTIONS The External Device Monitoring (EDM) function controls external devices by verifying the OSSDs status. EDM enabled When EDM is enabled it is necessary to connect the EDM input to a 24 VDC normally- closed contact of the device to be monitored. The figures below show how to connect the EDM input.
  • Page 95 The function controls the 24VDC normally-closed contact switching according to the changes of the OSSDs status. Figure 17 - EDM timings The EDM status is antivalent with OSSDs: the timing diagram explains the relationship between the cause (OSSDs) and the effect (EDM) with the maximum permissible delay. DLSentinel makes it possible to adjust the maximum permissible delay between 200 and 1000 ms.

  • Page 96: Encoders

    FUNCTIONS ENCODERS In dynamic applications, the safety area can change according to the position, direction, and speed of the vehicle. A typical example is the use of the Safety Laser Scanner on an Automated Guided Vehicle (AGV). If the speed changes, the minimum safety distance changes accordingly (the faster the movement, the longer the distance).
  • Page 97 ENCODERS To configure the necessary zone sets for a dynamic application, enable the encoder function in the Zone Set configuration page on DLSentinel. Input Delay Max [msec] This parameter is valid when there are at least two Zone Sets. It determines the delay to apply between switching from one Zone Set to the next.
  • Page 98 FUNCTIONS • If the vehicle speed is in the range between -30 cm/s and -10 cm/s or +10 cm/s and +30 cm/s, the Encoder Δ can be exceeded for max. 60 s. • If the vehicle speed is in the range ≤ -30 cm/s or ≥ +30 cm/s, the Encoder Δ can be exceeded for max.
  • Page 99 ENCODERS In the example above, the EncR value is 10,000 / 125.66 = 79.58 p/cm. Therefore, on DLSentinel the rounded value “80” must be entered in the relevant Encoder [p/cm] field. The software will calculate the max. allowed speed based on this data. After setting the encoder values, the Zone Sets must be configured.
  • Page 100 FUNCTIONS Encoder 2 ratio = 60 p/cm 2 = 100,000 / 60 = 1,667 cm/s 2 = - 100,000 / 60 = - 1,667 cm/s Therefore, the maximum and minimum speeds that the Safety Laser Scanner can read equal respectively 1,667 cm/s and -1,667 cm/s. The Speed Ranges of each Zone Set can- not exceed these values.

  • Page 101: Dust Filtering

    A High Dust Filter Level is used in dirty environments to filter (ignore) detection of air- borne particles from being confused with objects to detect. The Laser Sentinel is less sensitive to dust and therefore avoids shutting down the machinery unnecessarily.

  • Page 102: Shut Off

    FUNCTIONS SHUT OFF The Shut Off function allows energy saving, which can be particularly useful when the Safety Laser Scanner is used in battery-powered applications (e.g. AGV). When the Safety Laser Scanner is in Shut Off status, some of its functions are deacti- vated, but the device is still active and ready to restore to normal operation when needed.
