With special task requirements in material conveyance, the blanking of individual beams may be required in order to ensure an efficient, continuous process while simultaneously guaranteeing safety.

The COMPACTplus-b type 4 Safety Light Curtains in accordance with IEC/EN 61496 have been designed with these requirements in mind. They provide blanking functions for blanking any amount of beams and beam areas of varying sizes. Work pieces, for example, consequently pass through the protective field without interruption. By setting a reduced resolution, thin plates or tubes can also move through the protective field. COMPACTplus Safety Light Curtains and Multiple Light Beam Safety Devices can be equipped with various functions to optimally perform specific tasks with regard to higher functionality, more flexible integration and easier operability.

The COMPACTplus series have a start/restart interlock, contactor monitoring and additional functions that can be easily activated with switches. External additional modules are therefore no longer required. Specific settings are made with the diagnostics and parametering software, SafetyLab. COMPACTplus can be connected to both conventional safety modules and to open safety bus systems via various interfaces (transistor/relay output, AS-Interface Safety at Work, PROFIsafe). These safety sensors can therefore be flexibly integrated into existing automation environments.

The proper, specification-compliant, time-restricted bridging of a protective device (Muting) is required in numerous instances for a continuous, and therefore efficient production process, when conveyor vehicles, work pieces or palettes have to pass a protective field without interrupting the process, for example. The COMPACTplus-m type 4 Safety Light Curtains in accordance with IEC/EN 61496 are predestined for these requirements. They have integrated Muting functions and, controlled by Muting sensors, they can therefore be switched inactive. After the relevant objects have passed by the safety function is automatically activated again.

A cycle control can be extremely advantageous in increasing productivity, when work pieces have to be fed into or taken out of a machine by hand through a protective field, for example. The cycle control is used here for activating the machine movement after the feed-in and release of the protective field. For optimum arrangement of a production process with cycle control the COMPACTplus-i type Safety Light Curtains in accordance with IEC/EN 61496 provide integrated cycle control functions for different cycle operating modes. Numerous production applications can be activated with the freely selectable cycle mode (1 to 8 cycles).

Devices and protective systems must meet special requirements with use in explosion-risk areas.

Built into pressure-resistant glass cylinders of the Ex protection type "d" under the name COMPACT EX1, various models of the COMPACT Safety Light Curtains are available, tailor-made for these types of applications, i.e. for use up to Ex zone 1 (gases) and Ex zone 21 (flammable dusts) - with the typical benefits of the COMPACT series with regard to higher interference immunity and availability. In addition to the requirements of machine safety, COMPACT EX1 also satisfies the provisions of ATEX Directive 94/9/EC.

The glass cylinder housed in the COMPACT Safety Light Curtain is firmly closed with a lid. Robust cable bushings in the lid safely enclose the cables suitable for explosion-risk areas, which are to be provided by the customer. COMPACT EX1 can be used in industrial applications, however it cannot be used in pits. The device complies as an electrical piece of apparatus of EX device group II, EX category 2.

Devices and protective systems must meet special requirements with use in explosion-risk areas.

COMPACT EX2 with the "non-sparking" ignition protection type and special precautions on the transmitter and receiver housing is available in different models for these types of applications, i.e. for use in Ex zone 2 (gases) and in Ex zone 22 (flammable, non-conductive dusts) - with the typical advantages of the COMPACT series with regard to interference immunity and availability. In addition to the requirements of machine safety, COMPACT EX2 also satisfies the provisions of ATEX Directive 94/9/EC.

A reliable and interference-proof safety sensor system is a prerequisite for high system availability and achievement of production targets. At the same time the increasing costs pressure of global competition also requires an economical safety system.

Satisfying these central requirements was the maxim with the development of the SOLID-2 type 2 Safety Light Curtains with integrated cyclical testing. These devices are characterized by their robust housing design and high interference immunity.

Various resolutions and functionalities enable cost-optimized solutions with the most varied applications. SOLID-2 is predestined for hand and arm protection and for detecting the presence of people.

Rapid market changes require flexible production line adjustments. This demands long-life safety sensor technology that is versatile in its application.

Whether it be hand protection or danger zone and access guarding, the type 4 Safety Light Curtains of the SOLID-4E series provide reliable protection and ensure the highest possible system availability with their robust and interference-immune design. Protected by a warp-resistant profile housing closed on four sides and with their uncomplicated M12 connection system, they withstand even the toughest industrial conditions.

The restart interlock and contactor monitoring functions, and two different transmission channels for a fault-free operation of adjacent devices close to one another, are freely selectable. Versions in resolutions of 14, 20, 30, 40, 90 mm, which guarantee short mounting times due to their slender designs and versatile fixing options, ensure flexible, cost-optimized solutions.

Safety Laser Scanners are a cost-effective and flexible protective devices alternative for danger zone guarding of large areas in the vicinity of these machines. Switching between any kind of monitoring areas is possible with up to 6.25 radius, process-conditional according to the application. All configuration data, such as the definition of the zones, the resolution or the response times, is defined with the RS4soft configuration and diagnostics software.

Compactness, protective/warning field combination and field changeover are the essential features of Safety Laser Scanners for guarding corridor supply vehicles. The protection area of the traveling direction and speed of the vehicle is adjusted using staggered protective fields and their situation-conditional activation.

The Safety Laser Scanner also offers very significant advantages for portal processing systems. On one hand the vehicle can be monitored during the movement, while on the other hand, in standstill the Laser Scanner assumes a danger zone guarding of the tools integrated in the portal.

Safety Sensor Sets permit the efficient setup of access guarding. Both the preconfigured CPSET solutions with integrated Muting and the ROBUST-SET models with and without Muting function can be anchored permanently as free-standing devices using special foot elements. The components are electronically and mechanically optimally matched and specifically selected for the respective application. As a result, access guardings can be implemented easier, faster, and generally cheaper than with comparable individual components.

CPSET systems are Safety Sensor sets with integrated Muting, with both optoelectronic Muting sensors and induction loops. The configuration preset by the factory is already adapted to the respective application case. This minimizes the effort spent on planning and at the construction site. Conveyor systems are one of many possible applications for CPSET complete systems with integrated Muting and override functions.

ROBUST-SET systems contain pretty much everything required for the efficient setup of access guarding. The Muting function can be implemented with an additional MSI Safety Relay in the cabinet. Safety Sensor Systems ROBUST-SET provide reliable protection and, together with MSI Safety Relays, permit Muting as well.

The CPSET complete Muting systems provide Safety Sensor Sets for various Muting modes with all the necessary components.

The components are already preassembled, and are mechanically and electrically harmonized with one another. The factory-set parametering is already adjusted to the respective application instance and reduces input at the setup site to a minimum.

Depending on the model, in addition to the pre-parametered optical protective device, the CPSET complete systems also include suitable Muting sensors, including brackets, Device Columns with already installed devices, suitable cables, and with some sets, the necessary display and control units, which can be easily mounted on the hard guard.
