Selection and Application of Safety Interlock Switches

y

Historically, non-safety-rated proximity sensorsand mechanical limit switches have beenmisapplied and used in personnel safety

applications. These devices are not designed

specifically for safeguarding applications. They are

easy to defeat or bypass, and prone to failuremodes 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 safety

contacts have differentiated the design of switches

intended for safety use from that of standardcomponents.

Safety interlocking device application and design

requirements are addressed by several domestic,

international and regional standards, including:

ANSI B11.19, Performance Criteria for

Safeguarding,

ANSI/RIA R15.06, Safety Requirements for

Industrial Robots and Robot Systems, and

ISO 14119 (EN 1088), Safety of Machinery

Interlocking Devices Associated with Guards.

Safety Interlocking

It is important that the integration of safety interlockswitches, 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 (seepage 18 for safety system performance). While

safety interlock switches 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 or fastener breakage, and Physical damage to the interlocking device.

Because of the positive-opening design

requirement, 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 mechanical safety interlock switches, it is

usually necessary to use two devices and a safety

control system that continuously monitors both

devices for concurrent operation (see 2-ChannelMonitoring on page 19).

Installation

The physical installation of the mechanicalinterlocking devices is critical to the reliabilityof the system. The application standards which

detail the use and installation of these devices give

guidance on critical issues that affect systemintegrity. 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 helpin resolving some of these issues.

It is important for the designer to select the right

safety interlock switch 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 moreappropriate and in the long run will be a better

value for harsh-duty applications.

Use two safety interlock devices and a safety module for ahigh level of integrity.

Safety Interlock Types

Avariety of safety interlock designs address theunique requirements of safeguardingapplications. 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

A frequently used type 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 housingand a separate, coded actuator. The actuator is

usually mounted on the gate, and is aligned to a

slot in the interlocks housing, which is mounted

on the structure.

Once the actuator is fully

nested into the housing,

the safety contacts close,

allowing the machine

to run. When the

gate opens, thesafety 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 designedto break open resulting in a stop signal.

Rotary and Hinged Safety

Interlocks

Rotary and

hinge devices are

designed to mount

on the hinged side of an accessdoor. 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 machineframe, they are less likely to

be exposed to airborne dirt,

oil and mist, or tampering.

Guard Locking Safety 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 closedwhen there is no power to the solenoid; this mode

is preferred for personnel guarding applications

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. Powerlocking 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 solenoidcoils, before using

power-locking devices to safeguard personnel.

Magnetic Safety 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 to a 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 magnet

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.

application.

Fiber Optic, Non-Contact Gate and

Door Monitoring

A novel technique for gate and door

monitoring applies fiber optic cable and series-

connected fiber optic interlock switches to monitor

multiple access doors, gates and other hard

guards. This new system connects one or more

loops of plastic fiber optic cable to a control-

reliable photoelectric controller. Fiber optic

interlock switches are connected at critical

monitoring points in the loop(s) (see PICO-

GUARD, page 49).

The fiber optic switches mount on doors and door

frames, in much the same way as their mechanical

and magnetic counterparts. They are designed to

transmit the optical signals from the controller

through the fiber optic cable, from one switch to

the next, along the plastic fiber optic loop. If a

door or gate opens, the optical signal between

switches breaks, and the controller detects this

as an open door or unsafe condition. The absenceof the optical signal causes the controller's solid-

state safety outputs to turn off, which causes the

hazardous machine motion to stop.

This technology provides exceptional longevity,

due to the lack of moving parts or electrical

contacts. And because the switches use only light,

not electrical current, they are ideal for use in

hazardous (explosive) environments, or in areas

with high levels of electrical or RF noise. In

addition, a single optical switch may be used tomonitor a door or gate, eliminating the need for

interlock switch redundancy. This unique single-

switch-per-door guarding method is designed to

meet IEC 61496-1 Type 4 and ISO 13849 (EN 954-1)

Category 4 requirements.

SI-MAG Series Switches Non-contact safety switches are the best choice for washdown applications; the switch

components are sealed and rated 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 (see note below)

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 198)- SI-MAG1C (page 200)
