PreventaTM Machine Safeguarding Products
Safety systems are comprised of many components, and no one safety component will ensure the safety of the system. The design of the complete safety system and level of safety desired must be considered before choosing products. 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 as part of the initial design, 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 and safety system architectures.
Safety PLCs—XPSMF
Safety PLCs are used where the safety solution is complicated, or where there are a greater number of safety inputs or outputs required. They are also used where safety inputs and outputs need to be distributed around the machine or production area.
Safety Controllers—XPSMC
Safety controllers are used in applications where multiple safety relays would be required to control the safety system, or where the interaction between the individual safety relays would require significant inter-wiring. The simple-to-use software allows the user to more easily develop the safety control system, providing a cost effective solution.
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.
AS-Interface Safety at Work—ASI
ASI provides the safety solution of multiple safety relays on a communication bus that can transmit both standard and safety relevant data. The safety solution is simply configured with the easy to use configuration software.
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.
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 and its actuating key is desired, such as in food and beverage applications, so we also provide several different types of XCSDM non-contact safety interlock switches.
In some applications, the position of components is important to the safety of the machine, and devices such as safety interlocks or light curtains are impractical. These applications are ideal for safety limit switches. They can also be used on gates and guards to verify a closed position or a fully open or overtravel position.
In some applications, 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 a more economical solution based on ease of use, installation time, and cost effectiveness.
Press applications demand two hand control units for operator protection that are large and easy to operate while wearing palm button gloves. Other press applications, such as stop and inch, also need large buttons for operators wearing gloves. The 9001 P palm buttons offer a variety of operators to meet these needs.
All of the machine safeguarding products discussed in this section are designed to work together to allow you to meet your Various safety requirements. These products will allow you to meet the highest safety levels, up to category 4 per EN 954-1 or SIL 3 per IEC/EN 61508, and help you meet domestic and international safety requirements, standards, and codes.
