2 Selection and Application of Interlock Switches Historically non-safety-rated proximity sensors and mechanical limit switches have been misapplied and used for personnel safety applications. These devices are not specifically designed for safeguarding applications. They are easy to defeat or bypass, and prone to failure modes which lead to potentially dangerous situations. Newer design and application standards have addressed this issue by requiring coded systems that cannot be easily defeated with such readily available objects as tape, magnets, or metal objects. Manufacturers have responded with new designs that satisfy safety use requirements. Mechanical devices with positive-opening operation of the safety contacts have differentiated the design of switches intended for safety use from that of standard components. interlocking device application and design requirements are addressed by several domestic, international and regional standards, including: ANSI B11.19, Safeguarding Requirements when Referenced by other B11 Standards, ANSI/RIA R15.06, Requirements for Industrial Robots and Robot Systems, and ISO and EN1088, of Machinery Interlocking Devices Associated with Guards. 186 Banner Engineering Corp.

3 Selection and Application of Interlock Switches Interlocking It is important that the integration of safety interlocks, used as part of a safety system design, fulfill the safety requirements of redundancy and monitoring functions in order to maintain a high level of system integrity (see page 20 for safety system performance). While safety interlocks are designed for safeguarding applications, many are simple mechanical systems that can fail in an on state, under certain circumstances. Possible mechanical and electrical failures of these devices must be considered when incorporating integrity into a safety system design. Possible failure modes include: Short circuits across the outputs, Actuator fastener breakage, and Physical damage to the interlocking device. Because of their positive-opening design requirements, a mechanical safety interlock device may fail with its safety contacts closed, should its head be sheared off or removed. To obtain a high level of safety system integrity using safety interlock devices, it is usually necessary to use two devices and a safety control system that continuously monitors both devices for concurrent operation (see dual channel monitoring on page 21). Use two safety interlock devices and a safety module for a high level of integrity. Installation The physical installation of the mechanical interlocking devices is critical to the reliability of the system. The application standards which detail the use and installation of these devices give guidance on critical issues that affect system integrity. Some common problems include: Using the safety interlock as an end of travel doorstop, Unreliable fasteners, Improper use of mounting holes, and Improper actuator alignment and/or doors that do not have repeatable position, causing physical damage to the mechanical interlock. Special flexible and adjustable actuators can help in resolving some of these issues. Flexible actuator It is important for the designer to select the right safety interlock for each application. Although the size and price of light-duty plastic devices may be attractive, a larger metal safety interlock, carrying a higher price, may be more appropriate and in the long run be a better value for harsh-duty applications.

4 Selection and Application of Interlock Switches Interlock Types Avariety of safety interlock designs address the unique requirements of safeguarding applications. The goals of all designs include: Reducing defeat potential, Providing reliable operation of the safety outputs Reliably monitoring the function of the device, and Withstanding expected environmental influences that could introduce faults. Standard Mechanical Interlocks One of the most common types of safety interlock is what the international and European standards call a functional category 2 device. A functional category 2 safety interlock has two components: the safety interlocking housing and a separate, coded actuator. The actuator is usually mounted on the gate, and is aligned to a slot in the housing, which is mounted on the structure. Functional Category 2 Interlock Actuator and switch are switch two are separate components two separate components Once the actuator is fully nested into the housing, the safety contacts close, allowing the machine to run. When the gate opens, the safety contacts are forced open by a mechanical action referred to as positive opening, which sends a stop signal to the machine. Positive opening is required for safety application use; it ensures direct mechanical action in opening the safety contacts and does not depend on springs to perform the safety function. Even in a welded contact condition, the safety contacts are designed to break open resulting in a stop signal. Rotary and Hinged Interlocks Rotary and hinge devices are designed to mount on the hinged side of an access door. They are termed functional category 1 devices by the international and European standards systems. In effect, functional category 1 safety interlocks have one-piece construction; the actuator is an integral part of the housing. These devices have no slot or nest where dirt or other materials can collect and cause problems. And because they are usually mounted out-of-the-way in the machine frame, they are less likely to be exposed to airborne dirt, oil and mist, or tampering. Guard Locking Interlocks Guard locking devices have a separate actuator, and use a solenoid system to lock the engaged actuator in place. The solenoid not only monitors the gate for open or closed position, but also holds the gate closed, preventing access to the machine until it is verified that the machine is in a safe state. These devices can be useful for machines that have relatively long stop times and where entering the machine during the process can cause damage to material (in addition to the injury issue). The control signal that unlocks the door likely comes from a safety-rated stop-motion-detection system or safety timer. The two most common locking modes for guard locking devices are spring locking and power locking. Spring locking holds the gate closed when there is no power to the solenoid and is preferred for personnel guarding applications 188 Banner Engineering Corp. Minneapolis, U.S.A. Tel:

5 Selection and Application of Interlock Switches because the locked state does not require an external positive signal. Spring-locking devices must have a means of manually overriding the lock to allow machine maintenance (lockout/tagout procedures). The override must also be limited to authorized personnel. Power locking requires the solenoid to be energized by an external control device in order to achieve the locked state. Consider possible solenoid failure modes, such as broken wires, supply voltage failure and failed solenoid coils, before using power-locking devices to safeguard personnel. Magnetic Interlocking When standard mechanical safety interlocks do not fit application needs due to environmental issues, size, or mechanical limitation, magnetic safety interlocking may be an option. Although several domestic, international and European standards warn against use of simple proximity devices for gate monitoring, specially-designed magnetic safety interlock systems have been introduced into the market for personnel safeguarding application. A magnetic safety interlock has a sensor and a magnetically coded actuator. Within the sensor are multiple magnetically-actuated reed contacts that must match up with a specifically-coded actuator, in order for the machine to run. This magnetic coding is not only redundant in design, but also defends against bypass using a simple magnet. Benefits of magnetic interlocks include their relatively small size, higher housing protection rating and non-contact operation. Because the actuator does not need to make physical contact with the sensor, such factors as metal fatigue, clogged actuator slots and close tolerance are not an issue.
