    Important User Information Solid state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls (publication SGI-1.1 available from your local Rockwell Automation sales office or online at http://literature.rockwellautomation.com) describes some important differences between solid state equipment and hard-wired electromechanical devices. Because of this difference, and also because of the wide variety of uses for solid state equipment, all persons responsible for applying this equipment must satisfy themselves that each intended application of this equipment is acceptable. In no event will Rockwell Automation, Inc. be responsible or liable for indirect or consequential damages resulting from the use or application of this equipment.

    The examples and diagrams in this manual are included solely for illustrative purposes. Because of the many variables and requirements associated with any particular installation, Rockwell Automation, Inc. cannot assume responsibility or liability for actual use based on the examples and diagrams.

    No patent liability is assumed by Rockwell Automation, Inc. with respect to use of information, circuits, equipment, or software described in this manual.

    General Safety Information

    This application example is for advanced users and assumes that you are trained and experienced in safety system requirements.

    A risk assessment should be performed to make sure all task and hazard combinations have been identified and addressed. The risk assessment may require additional circuitry to reduce the risk to a tolerable level. Safety circuits must take into consideration safety distance calculations which are not part of the scope of this document.

    Contact Rockwell Automation to find out more about our safety risk assessment services.

    Description This machine safeguarding application example shows the wiring configuration and programming setup in which the SmartGuard 600 controller controls a TLS-GD2 guardlocking interlock that is connected to an ArmorBlock Guard I/O connection block module.

    The SmartGuard 600 controller is programmed using RSNetWorx for DeviceNet software. You must be familiar with this software to use this document.

    Safety Function The safety gate remains closed and locked while the machine is running. Access to the hazardous area is accomplished by applying a signal to the solenoid in the TLS3-GD2 interlock. While the TLS3-GD2 interlock is unlocked or the gate is open, the hazards cannot start. For this example, the hazards are controlled by two 700S safety control relays.

    The TLS3-GD2 interlock is a solenoid-operated guardlocking interlock used to maintain a gate in a locked state until a signal is received from the machine control. The TLS3 interlock has two normally-closed contacts that monitor the status of the actuator and two normally-closed contacts that monitor the status of the solenoid.

    Internally, two jumpers are needed, one from terminals 12 to 41, and a second from 22 to 51. The jumpers are installed in the factory for the part number listed in the example bill of materials. This wiring configuration places the actuator contacts in series with the solenoid contacts. This allows the safety system to prevent startup when either the door is open or if the door is unlocked.

    To maintain the integrity of the Category 3 safety performance level (single fault tolerance), the TLS3-GD2 interlock must be installed per its installation instructions and operated within the following specifications:

    Alignment of actuator over the expected life Protection against overspeed of the actuator Mechanical stops provided to prevent the actuator from hitting

    the TLS3-GD2 housing during closing Mounted with robust hardware

    Using the TLS3-GD2 interlock in an environment for which it is designed.

    Setup and Wiring For detailed information on installing and wiring, refer to the product

    manuals listed in the Additional Resources on page 23.

    Currently, there is no cordset available that connects the TLS3-GD2 (8-pin) directly to the M12 connectors on the ArmorBlock Guard I/O module (5-pin). The two QD cordsets listed in the Bill of Material on page 4 let you construct a Y cable, as shown below.

    Configure the DeviceNet Network This application example uses three devices as seen in the graphics tab of

    RSNetWorx for DeviceNet software. Node one is used to configure and program the SmartGuard controller (node two) and the ArmorBlock Guard I/O module (node three).

    Refer to the SmartGuard 600 Controllers User Manual, publication 1752-UM001, and the SmartGuard 600 Controllers Safety Reference Manual, publication 1752-RM001, for information on using the SmartGuard 600 controller on a DeviceNet network.

    ArmorBlock Guard I/O Module Setup

    These steps explain how to set up the ArmorBlock Guard I/O module parameters, test the outputs, and turn on the test pulses.

    1. On the network graph (in the offline mode), double-click the node three icon.

    2. Click the Safety Configuration tab.

    In the wiring diagram, the TLS3-GD2 interlock is connected to Input Points 02/03.

    3. Double-click the Input Points 02/03 line.

    4. Since this is a dual-channel circuit with two normally-closed contacts, set the operation (parameter 57) to Equivalent.

    This is so both contacts are open and closed at the same time and should always be in the same state.

    5. Click the current value field of parameter 57.

    6. From the pull-down menu, choose Equivalent.

    The modes for both channels (parameters 33 and 37) are configured as Safety Pulse Test, as they perform a safety function. Different test sources for each channel are used to detect cross-channel shorts (a fault condition).

    7. Set parameter 34 to Test Source 2.

    8. Set parameter 38 to Test Source three.

    9. In the same dialog, scroll down and double-click Test Output Points.

    10. Turn on the test pulses by setting the current value of Test Output 02 Mode to Pulse Test.

    11. Repeat this for Test Output 03 Mode by clicking the Not Used value in the desired row.

    12. Select Pulse Test from the Current Value pull-down menu.

    13. Scroll down and double-click Output Points 02/03.

    The TLS3-GD2 solenoid is connected to output points two and three. The default operation is Dual.

    14. Click the value for the Output 02 Mode and change it from Not Used to Safety.

    15. Click the value for the Output 03 Mode and change it from
