Protect your personnel and processes with LS-Titan•

In today’s environment, nothing is more important than ensuring the utmost safety of your employees. On the plant floor, the use of safety-rated control products can mitigate many of those risks when they are applied correctly as part of a safety control system.

Arguably, the most critical safety point on the plant floor is man-machine safeguarding. Heavy equipment—such as metal stampers, woodworking machinery, conveyors and assembly equipment—can present an unreasonable risk of injury if not properly safeguarded.

To provide protection in these applications, Eaton has introduced LS-Titan: a full line of safety-rated limit switches designed specifically to protect personnel and processes. More than 100 switch models make up the LS-Titan line, and offer comprehensive solutions to a wide range of applications.

An important safety feature of LS-Titan is provided by positive opening contacts (per IEC/EN 60947-5-1). “Positive opening” describes a switch designed with normally closed (NC) electrical contacts which, upon switch actuation, are forced open by a nonresilient mechanical drive mechanism. A conventional limit switch is typically designed to use a spring force to open normally closed electrical contacts,

presenting potential hazards should the switch contacts become “stuck” or “welded” shut. Consequently, such designs are not recognized as suitable for safety applications.

Beyond the safety functionality of positive opening contacts, design engineers and safety professionals have long recognized the need to use tamper-resistant key interlocks. In many factories, workers often override or bypass safeguards intended to protect them from injury. The LS-Titan family includes a complete selection of safety interlock devices designed to be difficult to defeat using simple, readily-available means such as paper clips, screwdrivers, and other common tools.

A highlight of the LS-Titan switch line are the world’s first electronic position switches (LSE models). These models come in two variants: one with the ability to output an analog signal (4–20 mA or 0–10V) proportional to the actuating lever’s position; and another model which can easily be set in the field to trip at a certain point—using just a screwdriver for adjustment. These features, which in the past required additional logic and more complex control systems, can now be accomplished within the switch itself. Both models carry TUV Functional-Safety certification and include built-in safety features, such as self-testing and diagnostic outputs.

Miniature Din style

At the core of the LS-Titan switch family are miniature DIN (IEC type) safety-rated limit switches. At just 22x34x76 mm and economically priced, these switches are perfect for a wide variety of packaging, material handling, and other machinery OEM applications.

a versatile offering

The LS-Titan family has been designed for application flexibility. A wide selection of interchangeable heads are available, and can be rotated in four different directions. Switches can

be ordered as complete (composite) units, with heads already installed, or as separate modular components. Depending on the needs of the application, LS-Titan switches can be ordered in plastic (totally insulated) or metal enclosures. And it’s not just the switch bodies—most of the switch heads can also be ordered in either plastic or metal. easy to install, fine-tune and maintain

Installing and maintaining LS-Titan switches couldn’t be easier, since operations can be performed with a flat-head screwdriver. To remove the switch head from the body,

just unscrew the front switch plate and twist counter-clockwise. To wire the switch, simply unscrew the front plate and secure the wires using the internal screw terminals. To select a custom trip point (for LSE models) use a screwdriver to adjust the potentiometer located inside the enclosure. These smart design choices simplify installation and maintenance significantly.at home in safety applications

Equipped with double-break contacts, LS-Titan safety position limit switches are also suitable for use in the configuration of redundant safety circuits. The switches

featuring double break contacts are suitable for use with electronic devices in accordance with IEC/EN 61 131-2, enabling the safe exchange of information with any controller.When it comes to protecting your personnel and most vital factory processes, trust LS-Titan.

One of the most dangerous applications on the plant floor involves the man-machine interface, particularly when it involves heavy or moving machinery. These hazardous areas are usually protected with guards that prevent tampering while the machine is operating. protecting personnel from dangerous processes

Eaton’s LS-Titan safety interlock switches have been specifically designed for monitoring the position of protective guards such as doors, flaps, hoods and grilles. Switches in this family are safety-rated, include positive opening N.C. contacts, and cannot be defeated using simple tools such as pliers, screwdrivers and nails.The LS-Titan safety interlock family is comprised of three types of safety switches: key interlock, door-flap and door-hinge switches.

applying key interlocks

Key interlock switches are a two-piece design, made up of the switch and key (actuator). The key portion of the switch is affixed to a movable door, cover or other guard. The switch itself is mounted to a rigid portion of the machine. When the guard is opened, the key is removed from the switch, thereby positively breaking the normally closed contacts. This interrupts the control circuit, stopping machine operation.Solenoid-powered interlocks for increased protection

Offering the highest level of personnel protection, the LS-Titan solenoid key interlocks are available in power-to-lock or power-to-unlock models. These solenoid-operated models also include a wide variety of different keys for lid-type doors, sliding doors,

doors that close at an angle and doors that do not close precisely. Specialty interlocks for unique applications

The door-flap and door-hinge switches are one piece designs, suitable for when a key cannot be mounted in the application. When an attempt is made to open a protected door hinge or flap during operation, these switches disconnect the power supply to the machine or installation.

Both switches feature four-way adjustable heads.When it comes to protecting your employees from dangerous industrial applications, Eaton’s LS-Titan interlocks have you covered.

Introduction

Technical Reference LS-Titan To protect personnel and

equipment, often the need arises for a device to provide a signal indicating that a door or a panel has been closed before a machine can be turned on or operations can be restarted.

While a standard limit switch or sensor may be able to do this function, the possibility exists that the unit could be false tripped or false actuated either accidently or deliberately, thereby posing a danger to the machine operator.

In response to this problem, many switch manufacturers offer safety-rated interlock switches.

Designed with two parts—the sensor and the actuator, the sensor is typically mounted on the stationary portion of a structure and the actuator is mounted on the movable portion. The sensor is designed to work with the correct actuator (keyed or coded magnet) to reduce tampering and increase safety.

Interlock Switch

Actuation of the interlock switch occurs only when the corresponding key is inserted into the key slot. The key is usually mounted on a door or machine guard in such a way that when the door or the guard is closed, the key fits into the slot actuating the switch. The special key design makes the safety interlock switch extremely difficult to defeat. When inserted into the slot, the key performs three separate mechanical functions.

In addition to being difficult to override, the safety interlock is also designed to fail to a safe mode. If, by chance, the contacts were to become welded together, removal of the key will physically tear the contacts apart, resulting in a safe condition.

LS-Titan™ key interlock switches by Eaton’s Electrical Sector are available in both NEMA® and DIN style housings. NEMA style key interlock switches feature durable metal housings, which remove power to the machine when the guard is opened.

DIN style key interlock switches feature a reduced size and economical plastic housings. They remove power to the machine when the guard is opened.

Non-Contact Interlock Switch

Activation of the non-contact interlock switch occurs only when the corresponding magnetic actuator is within operating range. The actuator is usually mounted on a door or machine guard in such a way that when the door or the guard is closed, the actuator is within operating range and actuates the sensor. The design of the sensor/actuator combination reduces the likelihood of defeating the sensor with a simple magnet.

All switches in this family are safety-rated, include positively opening NC contacts, and cannot be defeated using simple tools, such as pliers, screwdrivers and nails.

The LS-Titan safety interlock family is comprised of three types of safety switches: key interlock, door-flap and door-hinge switches.

Key interlock switches are a two-piece design, made up of the switch and key (actuator). The key portion of the switch is affixed to a movable door, cover or other such guard. The switch itself is mounted to a rigid portion of the machine. When the guard is opened, the key is removed from the switch, thereby positively breaking the NC contacts. This interrupts the control circuit, stopping machine operation.

The door-flap and door-hinge switches are one-piece designs, suitable for when a key cannot be mounted in the application. When an attempt is made to open a protected door hinge or flap during operation, these switches disconnect the power supply to the machine or installation. Both switches feature four-way adjustable heads.

All LS-Titan safety interlock switches are approved to protect personnel and processes.

RS Safety Interlock SwitchesProduct DescriptionEaton’s RS safety interlock switches have been specifically designed for monitoring of protective guards, such as doors, flaps and hoods. All switches in this family are safety-rated and use magnetically coded actuators to minimize defeat by simple magnets. With correct installation, the RS family complies with EN ISO 13849-1 and IEC 62061 guidelines.

OperationThe RS safety interlock family is comprised of three series: RS2, RS2R and RS4. The assembly comprises a sensor component and a separate magnet actuator component. The sensor is typically mounted to a stationary portion of a structure and the magnet to a movable portion. When the sensor and the actuator are within operating range, the NC contacts will be closed and the NO contacts will be open.

Features● Non-contact actuation● Reversible mounting● High misalignment

tolerance● Up to SIL 3 and up to

PLe ratings● –10 to +55°C temperature

range● IP67

Standards and Certifications● IEC 61508● ISO 13849● EN 1088● cUL● CE● TÜV

Understanding LS-Titan Electronic Safety Position Switches

All four LS-Titan LSE switch bodies are safety-rated products. The LSE-11 and LSE-02 switch bodies both have a freely programmable operating point and can be individually adjusted to suit the application, and can be changed as often as required. These devices feature an LED on the body, providing simple indication during programming and operation.

The LSE-AI (4–20 mA) and LSE-AU (0–10V) analog position switches take position data and convert to an analog current or voltage value that can then be continuously fed into an automation system. These two switches also feature a diagnostic output for additional data processing.

NotesLSE-11 and LSE-02—individual operating point adjustment.

LSE-11 and LSE-02 can be used in safety circuits. S1 is connected to 24 Vdc S2, S3 each switch with a delay of 0.7s R1, R2, e.g., series element M22-XLED60 (2820 ohms/0.5W)

This ensures that a safe operating state can be monitored and evaluated at any time. A self-test function is also present on these models. Outputs Q1 and Q2 are continuously tested for overloads, short circuits to 0V and short circuits to +Ue.

Like the electromechanical position switches, LS-Titan electronic position switches meet Category 3 or 4 of the EN 954-1 standard for machine safety when configured as a redundant system. All devices are thus suitable for safety applications that are used for the protection of persons or processes.

LS-Titan Safety Interlock SwitchesProduct DescriptionEaton’s LS-Titan™ safety interlock switches have been specifically designed for monitoring the position of protective guards, such as doors, flaps, hoods and grilles. All switches in this family are safety-rated, include positively opening NC contacts, and cannot be defeated using simple tools, such as pliers, screwdrivers and nails.

The LS-Titan safety interlock family is comprised of three types of safety switches: key interlock, door-flap and door-hinge switches.

Key interlock switches are a two-piece design, made up of the switch and key (actuator). The key portion of the switch is affixed to a movable door, cover or other such guard. The switch itself is mounted to a rigid portion of the machine. When the guard is opened, the key is removed from the switch, thereby positively breaking the NC contacts. This interrupts the control circuit, stopping machine operation.

The door-flap and door-hinge switches are one-piece designs, suitable for when a key cannot be mounted in the application. When an attempt is made to open a protected door hinge or flap during operation, these switches disconnect the power supply to the machine or installation. Both switches feature four-way adjustable heads.

All LS-Titan safety interlock switches are approved to protect personnel and processes.

Features● Broad family of safety

interlock switches in industry-standard enclosure sizes: miniature DIN; full-size DIN; and larger, solenoid key interlocks providing the highest degree of personnel and process protection

● Large selection of actuators (keys), including those for sliding doors, swing doors and doors that do not close precisely

● Miniature DIN models have a five-way adjustable head, while full-size DIN models have four-way adjustable heads

● Fully safety-rated as interlocking devices per EN 1088, with safety function by positive opening contacts per IEC/EN 60947-5-1

● Door-flap and door-hinge safety switches provide a unique solution when actuators (keys) cannot be used

● IP65 degree of protection

Standards and Certifications● UL® listed● CSA® approved● CCC

● Positive opening NC contacts per EN 60947-5-1
