Selection and Application of Safety Interlock Switches
Historically non-safety-rated proximity sensorsand mechanical limit switches have been
misapplied and used for personnel safetyapplications. These devices are not specificallydesigned for safeguarding applications. They areeasy to defeat or bypass, and prone to failuremodes which lead to potentially dangeroussituations.
Newer design and application standards haveaddressed this issue by requiring coded systemsthat cannot be easily defeated with such readilyavailable objects as tape, magnets, or metalobjects. Manufacturers have responded with newdesigns that satisfy safety use requirements.Mechanical devices with positive-openingoperation of the safety contacts have differentiatedthe design of switches intended for safety usefrom that of standard components.
Safety interlocking device application and designrequirements are addressed by several domestic,international and regional standards, including:
• ANSI B11.19, Safeguarding Requirements whenReferenced by other B11 Standards,
• ANSI/RIA R15.06, Safety Requirements forIndustrial Robots and Robot Systems, and
• ISO 14119 and EN1088, Safety of Machinery –Interlocking Devices Associated with Guards.

Safety Interlocking
It is important that the integration of safetyinterlocks, used as part of a safety system
design, fulfill the safety requirements ofredundancy and monitoring functions in order tomaintain a high level of system integrity (see page20 for safety system performance). While safetyinterlocks are designed for safeguardingapplications, many are simple mechanical systemsthat can fail in an “on” state, under certaincircumstances. Possible mechanical and electricalfailures of these devices must be considered whenincorporating 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 designrequirements, a mechanical safety interlock devicemay fail with its safety contacts closed, should itshead be sheared off or removed.
To obtain a high level of safety system integrityusing safety interlock devices, it is usuallynecessary to use two devices and a safety controlsystem that continuously monitors both devicesfor concurrent operation (see dual channelmonitoring on page 21).
Installation
The physical installation of the mechanicalinterlocking devices is critical to the reliability
of the system. The application standards whichdetail the use and installation of these devices giveguidance on critical issues that affect systemintegrity. Some common problems include:
• Using the safety interlock as an end oftravel 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 mechanicalinterlock.
Special flexible and adjustable actuators can helpin resolving some of these issues.
It is important for the designer to select the rightsafety interlock for each application. Although thesize and price of light-duty plastic devices may beattractive, a larger metal safety interlock, carryinga higher price, may be more appropriate – and inthe long run be a better value – for harsh-dutyapplications.
Use two safety interlock devices and a safety module for ahigh level of integrity.

Selection and Application of Safety Interlock Switches
Safety Interlock Types
Avariety of safety interlock designs address theunique 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 Safety Interlocks
One of the most common types of safetyinterlock is what the international andEuropean standards call a functional
category 2 device. A functional category 2 safetyinterlock has two components: the safetyinterlocking housing and a separate, codedactuator. The actuator is usually mounted on thegate, and is aligned to a slot in the housing, whichis mounted on the structure.
Once the actuator is fullynested into the housing,
the safety contacts close,allowing the machine
to run. When thegate opens, thesafety contactsare forced openby a mechanical
action referred to aspositive opening, which
sends a stop signal to the machine. Positiveopening is required for safety application use; itensures direct mechanical action in opening thesafety contacts and does not depend on springs toperform the safety function. Even in a weldedcontact condition, the safety contacts are designedto break open – resulting in a stop signal.
Rotary and Hinged SafetyInterlocks
Rotary and hinge devicesare designed to mount on the
hinged side of an access door.They are termed functional category 1 devices bythe international and European standards systems.In effect, functional category 1 safety interlockshave one-piece construction; the actuator is anintegral part of the housing. Thesedevices have no slot or nest wheredirt or other materials can collectand cause problems. Andbecause they are usuallymounted out-of-the-way inthe machine frame, they areless likely to be exposed toairborne dirt, oil and mist, ortampering.
Guard Locking Safety Interlocks
Guard locking devices have a separateactuator, and use a solenoid system tolock the engaged actuator in place. The
solenoid not only monitors the gate for open orclosed position, but also holds the gate closed,preventing access to the machine until it is verifiedthat the machine is in a safe state. These devicescan be useful for machines that have relatively longstop times and where entering the machine duringthe process can cause damage to material (inaddition to the injury issue). The control signal thatunlocks the door likely comes from a safety-ratedstop-motion-detection system or safety timer.
The two most common locking modes for guardlocking devices are spring locking and powerlocking. Spring locking holds the gate closedwhen there is no power to the solenoid and ispreferred for personnel guarding applications

because the locked state does not require anexternal positive signal. Spring-locking devicesmust have a means of manually overriding thelock to allow machine maintenance(lockout/tagout procedures). The override mustalso be limited to authorized personnel. Power
locking requires thesolenoid to beenergized by anexternal control devicein order to achieve thelocked state. Considerpossible solenoidfailure modes, suchas broken wires,supply voltage failureand failed solenoidcoils, before using
power-locking devices to safeguard personnel.
Magnetic Safety Interlocking
When standard mechanical safetyinterlocks do not fit application needs due
to environmental issues, size, or mechanicallimitation, magnetic safety interlocking may be anoption. Although several domestic, internationaland European standards warn against use ofsimple proximity devices for gate monitoring,specially-designed magnetic safety interlocksystems have been introduced into the market forpersonnel safeguarding application. A magneticsafety interlock has a sensor and a magneticallycoded actuator. Within the sensor are multiplemagnetically-actuated reed contacts that mustmatch up with a specifically-coded actuator, inorder for the machine to run. This magneticcoding is not only redundant in design, but alsodefends against bypass using a simple magnet.
Benefits of magnetic interlocks include theirrelatively small size, higher housing protectionrating and non-contactoperation. Because theactuator does not needto make physicalcontact with thesensor, such factors asmetal fatigue, cloggedactuator slots and closetolerance are not anissue.

Limit Switch Style Safety Interlock Switches – 83 mm and 100 mm Model Selection
SI-LS83/100 Series Switches• Positive opening safety contacts (IEC 60947-5-1) (not dependent upon springs)• Limit switch design (EN 50047)• Mechanically-coded actuators utilize two independent operating elements to minimize
intentional tampering or defeat• Rotating head allows actuator engagement from four sides or four top positions; no tools
are required to rotate head• Low-profile design for limited space requirements; only 30.5 mm (1.3") depth• Tough, glass-reinforced thermoplastic housing; metal actuator• Choice of two in-line actuators, two adjustable radius actuators or a flexible actuator
• Insulated device (IEC 60947-5-1)
NOTE: This symbol for a positive opening safety contact (IEC 60947-5-1) is used in theSwitching Diagrams to identify the point in actuator travel where the normally-closedsafety contact is fully open.

• Insulated device (IEC 60947-5-1)
• Choice of two locking mechanism types:- Spring lock with energized solenoid release- Energized solenoid lock with spring unlock
• Two solenoid voltages available:- 24V ac/dc- 24 to 48V dc or 24 to 230V ac
• Choose either of two stainless steel actuator types:- Rigid in-line- Flexible in-line
• Actuator head rotatable in 90° increments and can be positioned for either horizontal orvertical actuation
• Choice of three switching contact configurations (with actuator engaged):- 1 normally-open plus 1 normally-closed- 2 normally-closed- 2 normally-closed plus 1 normally-open
NOTE: This symbol for a positive opening safety contact (IEC 60947-5-1) is used in theSwitching Diagrams to identify the point in actuator travel where the normally-closedsafety contact is fully open.

Locking Style Safety Interlock Switches – 100 mm Model Selection
SI-QM100 Series Switches• Positive opening safety contacts (IEC 60947-5-1) (not dependent upon springs)
• Protective Earth Terminal (IEC 60947-1)
• Actuators are keyed to discourage intentional tampering or defeat
• Choice of two locking mechanism types:- Spring lock with energized solenoid unlock- Energized solenoid lock with spring unlock
• Both types are available with choice of 24V dc, 120V ac, or 230V ac solenoid operatingvoltage
• Actuator head rotatable in 90° increments
• Monitor contacts for both switching contact and solenoid status
• Standard mounting hole pattern (EN 50041)
NOTE: This symbol for a positive opening safety contact (IEC 60947-5-1) is used in theSwitching Diagrams to identify the point in actuator travel where the normally-closedsafety contact is fully open.

Magnet Style Safety Interlock Switches – Model Selection
SI-MAG Series Switches• Non-contact safety switches are the best choice for washdown applications; the switch
components are sealed and rated NEMA 4X, IEC IP67
• Tolerant of dirt buildup, sensing distance, and alignment
• System consists of three components:- Coded magnet- Reed switch sensor- Controller module
• Magnet contains several differently-polarized magnets, and sensor contains pole-stable reedcontacts to minimize possibility of defeat
• Easy installation; can be concealed for added defeat resistance
• Sensor reed switches provide diverse input to the controller module
• Must be used with Gate Monitoring modules for safety applications- GM-FA-10J (page 172)- SI-MAG1C (page 174)
