Laser Scanner (Parent only)

Description

The Datalogic Laser Scanner (PR-DA-001-0489) is an essential tool to ensure safety in the workplace. It can be used in multiple orientations to monitor large areas while remaining discreet and unobstructive. It will stop a machine if any undesired person or object crosses its safety zone. A PC with an Ethernet port is required for configuration.
In order to use the Laser Scanner with MachineMotion AI, a Muting Safety Module (CE-SA-015-0001__2) is required, please refer to the safety installation guideline section for the wiring.
The Laser Scanner specifications are as follows:

• Maximum safe zone: 5.5 m radius.

• Maximum warning zone: 40 m radius.

• Detection angle: 275o.

• Total/partial dynamic muting available.

• Zone switching (bank switching) available.

• 12-pin M12 connector available for communication with Muting Safety Module (CE-SA-015-0001__2).

• 4-pin M12 connector available for programming and monitoring (via an Ethernet cable to a computer).

Getting Started

1. Assemble the Laser Scanner bracket and mount it at the desired location.

2. Download the latest version of the DL Sentinel software from here.

3. Connect scanner to PC with the provided programming cable.

4. On the PC, open the DLSentinel software, and navigate to Scanner > Discovery. Your scanner should appear on the left panel. Select your scanner. A warning window may appear asking to change your IP address. Select OK.

5. Align the IP address. To align the IP address, make sure DHCP is set to Static. Verify that the last number of the IP Local address is different from the last number of the IP address. In figure 3, the last digits are 122 and 71, which are different.

6. On the main screen of the DLSentinel software, select Open a Safety System configuration from PC. Open the initialization file and select the connected laser scanner from the panel on the left side of the screen

Parameters’ configuration

Perform the following steps to get access to the Configuration settings:

• Open the connected scanner in the DLSentinel software by navigating to Scanner > Discovery. The connected scanner will be visible in the left-hand column

• Select your scanner and click on the white arrow at the top-right corner of the screen

To set parameters, select Configuration to access a drop-down menu. For each item on the drop-down menu, enter the desired values in the appropriate fields (highlighted in yellow). More details are provided for each parameter below.

1. Outputs:    

   1. Auto Reset can be set to ENABLED or DISABLED. If the Laser Scanner boots with an error (such as both zones are activated, or no zones are activated), this function will automatically restart the Laser Scanner after 10 seconds. However, if the device locks in INTFx more than five times within 15 minutes (see Datalogic documentation for more details), Auto Reset will not activate, and a power cycle will be required to reactivate the device. It is recommended to set Auto Reset to ENABLED to avoid booting errors.

2. Zone Set:    

   1. Zone Set No. can be set to 1 or 2. Use two zones when independent muting of different areas is required (such as for a palletizer with two zones). When setting two zones, click the “01010” icon to automatically fill the area switch pin association.        

      • Zone Set 1 active when Area Switch 1 = 1 and Area Switch 2 = 0

      • Zone Set 2 active when Area Switch 1 = 0 and Area Switch 2 = 1

      For a two-zone configuration, 1 1 and 0 0 are invalid Area Switch combinations. This will result in an error state. To resolve it, provide a signal to either Area Switch 1 or Area Switch 2 (effectively creating a 1 0 or 0 1 combination) and restart the Area Scanner.

3. Inputs:    

   1. Recovery time [msec] is the time delay between the object leaving the protected area and the OSSDs achieving the NORMAL OPERATION state. The minimum (default) value is 200 ms. It is recommended to keep the default value.

4. Detection    

   1. Number of scans controls the number of scans required to validate a detection. This parameter has a direct impact on Response time (more scans results in a longer response time).

   2. Detection capability [mm] is the ability to detect an object of given dimensions within the detection zone. Objects greater than or equal to the selected value can be detected in both the safety and warning zones.

   3. Dust Filter Level can be set to LOW, MID, or HIGH depending on the environment and the levels of airborne particles.Dust Filter Level should be set to the lowest value that still allows the Laser Scanner to work without detections due to dust.

5. Zones    

   1. Select the appropriate zone (Zone 1 or Zone 2, if there are two zones) in which to create the safety, warning and muting zones.

   2. To create a warning zone, click Warning 1, select a drawing tool from the right side of the screen (freehand, line, circle, arc, or polygon) and draw the desired warning zone. Multiple areas can be defined. The defined warning zones will appear yellow.

   3. To create a safety zone, click Safety 1, and repeat the same procedure as above for warning zones. Safety zones will appear red.

   4. To create a reference point, select the 6th icon down from the top right icons and place the point on a surface (such as a door frame or wall). Then set the tolerance. If the reference point moves outside the permitted tolerance, the OSSD will switch to an OFF state.

   5. NOTE: According to safety guidelines, when a laser scanner is monitoring a vertical plane, the safety zone should have a maximum gap of 180 mm from the bottom and a minimum height of 1400 mm when there are no height restrictions.

   6. Once satisfied with the configuration, click the Next white arrow in the top-right corner of the screen. Then click Load to upload the configuration to the area scanner. If prompted to enter a password, the default password is “admin” (this can be changed later). A warning will appear saying “Scanner status change in Off-Duty, continue?”. Select OK. Once the configuration is uploaded, click Accept to finalize the process.

   7. To ensure everything is working as expected, click Monitoring while plugged into the scanner to see a live feed of the scanner functioning.

If prompted to enter a password, the default password is “admin” (this can be changed later). A warning will appear saying “Scanner status change in Off-Duty, continue?”. Select OK. Once the configuration is uploaded, click Accept to finalize the process.

9. To ensure everything is working as expected, click Monitoring while plugged into the scanner to see a live feed of the scanners functioning.

For more information on various display icons that may appear on the Laser Scanner screen, refer to Datalogic’s Quick Guide for the SLS-M5-0812-E (Parent Scanner) & SLS-R5-E (Child Scanner) models.

Troubleshooting

If the parent and the child scanners are not able to communicate to each other or cannot be configured together, make sure that they are all on the same firmware version.

If a child scanner is disconnected or missing from the cluster that has been programmed and uploaded, the parent scanner will fall into an endless power cycle loop. To solve this, either reconnect the missing scanner(s) or disconnect all children scanners and upload a parent-only configuration to the parent scanner (follow steps 2 to 6 in Getting started for the parent scanner) to regain access to the parent scanner. Then, reconnect the children scanners to the cluster and reconfigure the cluster as desired.

Light Curtain

Description

The Datalogic Light Curtain (PR-DA-001-0295 & PR-DA-001-0296) is a useful device to increase safety in various industrial applications. It is generally used to monitor and control the entry and/or exit of objects across a safety barrier.

Connecting to MachineMotion AI

Laser Scanner

The steps to connect the Laser Scanner to MachineMotion AI via the Muting Safety Module AI are as follows:

1. Connect the Laser Scanner to a Muting Safety Module (CE-SA-015-0001__2) to one of the DEVICE connectors using the Area Scanner Cable (CE-SA-104-0001)*.

2. Connect a MachineMotion AI Safety Extension Cable (CE-CA-102-5001__2) to the Muting Safety Module AI’s SAFETY OUT connector and MachineMotion AI’s SAFETY IN connector.

3. If muting is required, connect the muting sensor of the muting kit (CE-AP-002-0000__2) in pairs thanks to the Muting Sensor Y Adapter (CE-SA-107-0001). Then connect the adapter to the Muting Safety Module AI via the MUTING xA and MUTING xB connectors.

*If a cluster of Parent-Child Scanners are being used, make sure to make all daisy-chain connections prior to connecting to MachineMotion AI.

Note: If no other safety modules are being daisy-chained to the Muting Safety Module AI, a safety jumper (CE-SA-102-0001) must be used on the Muting Safety Module AI’s SAFETY IN connector. Safety Device Jumper (CE-SA-125-0001) must be connected to the unused DEVICE connectors.

Light Curtain

The steps to connect the Light Curtain to MachineMotion AI via the Muting Safety Module AI are as follows:

1. Connect the receiver and the emitter to CE-SA-106-0001 cable. Then, connect CE-SA-106-0001 to one of the Muting Safety Module AI’s DEVICE connectors.

2. Connect a MachineMotion AI Safety Extension Cable (CE-CA-102-5001__2) to the Muting Safety Module’s SAFETY OUT connector and MachineMotion AI’s SAFETY IN connector.

3. If muting is required, connect the muting sensor of the muting kit (CE-AP-002-0000__2) in pairs thanks to the Muting Sensor Y Adapter (CE-SA-107-0001). Then connect the adapter to the Muting Safety Module AI via the MUTING xA and MUTING xB connectors.

Note: If no other safety modules are being daisy-chained to the Muting Safety Module AI, a safety jumper (CE-SA-102-0001) must be used on the Muting Safety Module AI’s SAFETY IN connector. Safety Device Jumper (CE-SA-125-0001) must be connected to the unused DEVICE connectors.

Muting

The muting function automatically deactivates the safety status of the whole safety area (total muting) or part of it (partial muting). This feature is particularly suitable when an object, but not a person, has to pass through the dangerous area. This feature also allows carrying out cyclical operations without blocking a working machine.

Muting sensors must be placed according to the material’s length and speed so they can recognize passing objects (such as pallets, vehicles, etc). When using the Muting Safety Module AI, four muting sensors are required to perform a bidirectional muting.

Bidirectional muting is used for objects entering and leaving an area. In this case, four sensors must be used: two on one side of the safe zone (A1 and B1), and two on the other side (A2 and B2). Sensors A1 and A2 are connected together, and B1 and B2 are connected together. They should be spaced at a distance where two consecutive sensors are always triggered throughout the movement of the object across the safety zone.
