Safety systems are comprised of many components, and no one safety component will ensure the safety of the system. Also, there is no single safety product that is the panacea for all applications. The design of the complete safety system and safety level desired must be considered before products are chosen. When products are chosen, they must be the ones best suited for the applications, and must work together to ensure the safety level of the system. The whole safety system needs to be integrated into the initial design process, not added on after the machine is built. Square D/Telemecanique can provide a wide range of products for the protection of personnel for machine guarding applications.
To protect operators, maintenance, and other personnel, safety systems may require the interlocking of mechanical gates or guards. We provide both locking and non-locking mechanical XCS safety interlock switches in many body styles and contact arrangements.
Sometimes no contact between the safety interlock switch components is desired, such as food and beverage applications, so we also provide several different types of XCSDM non-contact safety interlock switches.
Some machine operations may not allow gates or guards to be used, and other applications require high visibility of the process or easy accessibility. For these applications XUSL light curtains may be the best choice and are available in many protected heights, minimum object sensitivities and configurations.
Emergency stopping is required to shut the machine down in case an emergency or problem arises. Where an individual emergency stop is required, the XB4/XB5 emergency stop push buttons are available in various types, sizes, and nameplates. On large machines or conveyors a high number of emergency stop operators may need to be installed. As more individual e-stop buttons are required, using an XY2 cable pull switch becomes more attractive and economical based on ease of use, installation time, and cost effectiveness.
To tie the whole safety system together, XPS safety relays are used to monitor the safety inputs, outputs, and feedback from the system to determine when the system is safe to start and when the system should be shut down. Safety relays may also be used for providing safety timing circuits, zero speed control, two hand control, elevator monitoring, press control, and many other functions.
Press applications demand two hand control units for operator protection that are large and easy to operate while wearing gloves. Other press applications, such as stop and inch, also need large buttons for operators wearing gloves. 9001 P offers a variety of operators to meet these needs.
