The safety switches, monitoring systems, and safety relays described in this section are designed to interlock safeguarding systems such as barrier guards, gates, covers, and shields. They can be used on exposed machinery, conveyors and handling equipment, as well as textile, packaging, and processing machines, robots and other types of machinery. They are designed to be used in various types of industrial environments.
Some of the safety switches have tamper-resistant enclosures, actuators and fasteners. They are not easily defeated because two independent components are required to actuate the switch. This minimizes accidental or deliberate operation of the switch by anything other than the correct actuator. These switches are designed for simple installation and maintenance by authorized personnel only. This increases the integrity of the system and helps provide a safer work environment for all employees.
Proper installation of these safety interlock switches is as important as the accurate design and manufacturing of the switches. It is critical that a safety interlock switch, monitoring system, or safety relay is installed as part of a suitable safety control circuit. All devices are shipped with complete installation instructions. The instructions are simple, but all installation work should be performed by qualified personnel.
The purpose of interlock switches is two-fold. First, when the interlock is open, the machine should not be able to start any hazardous motion. Second, if the interlock is opened during a machine cycle, the hazardous motion must stop quickly. The type of stop command, either emergency stop or top stop (machine stops in open or end-of-cycle position), can be critical, depending on the guard's location or the machine's ability to stop quickly.
Using the new ANSI, UL, NFPA 79, and Harmonized European standards for reference, interlocks must be designed, installed, and maintained in a control ­reliable configuration. The interface between the switch and the machine control system is very important to maintain reliability. If there is a high degree of risk associated with the machine, the interlock must have control reliability which means it uses redundant contacts and cross-checking (monitoring). The safety relays and monitoring systems shown on this site can be used to accomplish this.
When deciding what type of interlock switch is required on a machine, determine where the interlock will be most effective in the control circuit of the machine. To do this, a risk assessment/hazard analysis should be done first. This assessment should include the following:

1. frequency of exposure to the hazard: seldom, occasional, or frequent
2. probability of injury: unlikely, possible, probable, or certain
3. severity of injury: minor, serious, major, or fatal
   

Each of these must be considered separately. Each of these categories must also be considered for all stages of machine operation including installation, normal operation, maintenance, inspection, and removal from service. Remember, when interlocking guards, there are many factors that must be considered, including safety, reliability, convenience, production, and maintenance.
Note: This catalog uses NO for normally open contacts and NC for normally dosed contacts in the specifications and descriptions. All safety contacts are specified as normally open when the actuator is not inserted or actuating the switch.

These tamper-resistant safety switches can be used to interlock hinged, sliding, or lift-off guards. Closure of the guard or latch causes the actuator to enter the switch and release the dual antitamper locking cams. The actuator allows the main center cam to rotate and make the switch contacts. When opening the guard or latch, the actuator positively forces the contacts open due to the cam action built into the switch.
These versatile switches have multiple actuation entry positions. Actuators and conduit adapter are sold separately.

These switches are designed to prevent accidental or deliberate access while the machine is in motion. The mechanical locking feature is ideal for machines that have to finish a sequence, a program, or coast to a stop before the interlocked guard can be opened. The switches allow the guard to be mounted closer to the hazard than nonlocking switches.
The operating principle of these switches is simple. When the actuator enters the switch, it engages with and operates a tamper-resistant locking mechanism, closing the contacts in a similar way to the nonlocking switches shown above. This locks the actuator in and holds the guard closed. When the contacts are closed and the mechanism is locked in, the machine is allowed to start.
To open the guard, a separate signal is required to energize the solenoid which releases the locking mechanism after the machine has stopped or the cycle has finished. A timer or stopped-motion detector can be used for this signal (see below). The timer can be used on machines with a consistent coastdown time. The stopped-motion detector is available for machines that have a variable or inconsistent coastdown time. If power is lost, a supervised override mechanical release, built into the switch, can be used.
Actuators and conduit adapter are sold separately.

STOPPED-MOTION SENSING UNIT
This unit detects the stop condition of AC or DC motors by sensing the motor's back EMF (electromagnetic flux). This will function with motor control devices such as standard motor starters and variable speed drives. It has 1 NO and 1 NC outputs that switch when the motor speed reaches the adjustable limit (.01 to .10 volts). For example, the stopped­motion sensing unit can be used in conjunction with a locking-type safety interlock switch that can not be opened until the motor has come to a stop.

STOPPED-MOTION DETECTOR
The stopped-motion detector is designed to be used with locking safety switches (see above) that are applied to machines or robots with an inconsistent or variable coastdown time.
The stopped-motion detector has an on-delay that can be adjusted between 0.1 second and 40 minutes through a series of four time ranges. It also uses two independent proximity sensors and monitors two moving metal parts of the machine or robot. This means it can detect when hazardous motion has stopped. Should either sensor detect motion, the machine guard will remain locked. This capability is essential on machines which do not have a consistent coastdown time.

This switch is a cable and push-button emergency­stop device. At the same time it is used to provide an awareness barrier on exposed machinery, such as conveyors. This device enables this system to accommodate cable spans up to 248 feet (75 m).
The switch has a unique cam operation of the contact mechanism to give rapid, positive operation of the contacts. This mechanism also provides a failure to the safe condition if the cable goes slack or is cut, but is immune to nuisance tripping due to machine vibration. Should the cable be pulled, the contacts are opened, isolating machine power, and the latch engages. The machine cannot restart until the hazard has been corrected and the switch is reset. The switch is reset by turning the blue reset dial from the off position to the run position. This switch also incorporates a cable-tension indicator. This indicator assists in installation andmaintenance of the switch. A red mushroom-head emergency-stop button is provided on each switch. Optionally available is an indicator light as shown.
A cable tension kit, which includes thimbles, cable clamps and a turnbuckle, must be used with this switch (see below). This kit includes the components to properly tension the cable. When installing this switch on cable runs over 12 feet, one switch should be installed at both ends of the cable. The cables should be supported by eye bolts every 6-1/2 to 10 feet (2 to 3 m) along its length. They should also be used about one foot from each switch to ensure that all emergency-pull movement is transmitted to both units in a linear fashion. If this assembly is to go around a corner, a free-moving pulley should be used. Please consult the factory if this is required.

A handle-operated safety interlock switch is used to replace an existing handle and keyed interlock on a guard. Nonlocking and locking handle-operated switches are available and operate on a similar principle. When the handle (turning-lever actuator) is inserted into the switch and rotated 90º, the safety circuits close and allow the machine to start.
To open the guard using the nonlocking handle-operated switch, simply rotate the turning-lever actuator 90º counterclockwise.
To open the guard using a locking switch, a separate signal must be sent to energize the solenoid which will release the locking mechanism. The guard can then be opened by rotating the turning-lever actuator 90º counterclockwise.

TWO-HAND CONTROL RELAY
The two-hand control relay is designed to provide protection for the machine operator by requiring the use of both hands to actuate the machine. When the safety relay is tied in, the palm buttons must be depressed with .5 seconds of each other. If this does not happen, the safety outputs do not actuate and the machine will not operate. The outputs are verified every cycle to confirm proper actuation of the palm buttons.

SAFETY RELAYS
TYPICAL APPLICATIONS

• Interlocked Guards, Light Curtains, Laser Scanners, Safety Mats
• Machine Input/Output Signals

A safety relay is designed to connect safety devices, such as interlock switches, to the machine control circuit. It provides a switching action from the safety interlock switch, and can act as an intermediate relay to distribute a signal to multiple devices. The relay compares input and output signals, and provides failure to a safe condition if there is a failure in the interlocking interface control circuit.
Without a safety relay, faults and short circuits in a safety interlock switch can go undetected and can create a hazardous situation. The potential for faults exists in the power supply, relays, and switches as well as their associated wiring.
When using a safety relay, the wiring is monitored and compared. If a failure occurs in one area, it will be detected and a stop signal will be sent to the safeguarded machine.

The flexi safety controller offers a unique solution for safety-relevant applications. Instead of hard wiring with safety relays or using expensive programmable logical controllers (safety PLCs), the flexi safety controller allows for an easier customizable system. When the safety input devices are connected to the system, the logic is implemented using rotary DIP switches, eliminating the need for software.
Solid-state safety outputs, rated at 1.6 A each (3.2 A available per module), provide sufficient current capability to drive a variety of actuator loads without using electromechanical relays. Relay modules are also available for applications involving control voltages other than 24 VDC, for currents greater than 1.6 A, or for applications that require signal isolation using mechanical contacts.
The flexi safety controller system consists of a main unit and, as required, additional extension units and relay modules. Logic is implemented with rotary DIP switches on the front of each module. Logical combinations with multiple modules are easily set based on how the modules are combined.
