Our Bulletin 450L GuardShield™ POC safety light curtains are unlike traditional safety light curtains, which are based on separate transmitter and receiver units. Patented technology allows each transceiver to be used as a transmitter or receiver via an innovative plug-in module. The 450L-B is the basic model with on/off functionality. The advanced 450L-E model features integrated laser alignment, cascading, and integrated muting.

Connection over EtherNet/IP makes the 450L-E light curtain a smart safety device that enhances safety while providing connectivity through The Connected Enterprise®
Includes patented technology that allows each transceiver to be used either as a transmitter or receiver via an innovative plug-in module
Features an active protective field that senses over the entire length of a transceiver
Offers a wide range of protection heights 150…1950 mm (5.9…76.7 in.) in increments of 150 mm (0.5 ft)

The safety light curtains ULVT consist of the two components: transmitter and receiver. The distance between both components and the overall height result in those protection width and - height.

By the modular construction protection heights of 100mm to 1900mm are realizable. Special sizes are also available.

If an object is in the protection field, i.e. it is darkened at least one of the beams,

the two outputs of the receiver interrupt the dangerous movement of the machine, or prevent a start. A renewed start of the machine is in the operating mode with restart only possible by pressing the start push-button during a free protection field.

Several LED at the receiver display thereby the respective operating condition. The system detects an internal or external error the machine is immediately switched off and the LED in the transmitter or in the receiver shows by flashing the error status.

By the modular construction protection heights of 100mm to 1900mm are realizable. Special sizes are also available.

Transmitter and receivers operate synchronously, i.e. at the same point in time only a light beam and a reception item are active. The synchronisation is made by the first light beam and the first reception item. Between transmitter and receivers therefore no electrical connection is necessary.

The transmitter creates infrared light beams, which are switched on and off rapidly successively. The parallel light beams with a distance from 7,5mm are controlled by two a chip micro controllers. A resolution of 14mm is realised by the beam distance.

Synchronously to the light beams of the transmitter in the receiver all reception items are analysed by two a chip micro controllers. If an object is in the protection field, i.e. it is darkened at least one of the beams, the two outputs of the receiver interrupt the dangerous movement of the machine, or prevent a start. A renewed start of the machine is in the operating mode with restart only possible by pressing the start push-button during a free protection field.

Several LED at the receiver display thereby the respective operating condition. The system detects an internal or external error the machine is immediately switched off and the LED in the transmitter or in the receiver shows by flashing the error status.

The transmitter generates infra-red light beams flashing at high speed in synchronous action. The parallel light beams with a spacing of 7,5mm or 14,3mm are monitored by miocro-controllers. The receiver evaluated the arriving beams in synchronous action to the transmitter.

Due to the closeness of the beams, a resolution of 14 mm / 30 mm is achieved. If an obstacle is placed into the protective field, i.e. at least iner lieght beam is interrupted, the hazardous movement of the machine is stopped, i.e. a new start is not possible.

Conventional light curtains had dead zone where there are no beam axis at both ends. With SE4D the first beam axis placed right along the edges, detection can be performed along the entire area. Up to 3 sets (emitter/receiver) can be connected in series to cover L or U shaped configurations, or to guard both the front and back of a machine.
SE4D light curtain is equipped with a muting control function that causes a line to stop only when a person passes through the light curtain, but does not stop the line when an object passes through. The muting sensor and muting lamp can be directly connected to the light curtain. A special controller for muting is not required thus reducing cost.
Fixed blanking prevents the control output (OSSD1/2) from turning off when a specific beam is interrupted. This is used in applications where a specific beam is always interrupted. When the object is moved outside of the sensing area, the control output (OSSD1/2) turns off. Floating blanking function prevents the control output (OSSD1/2) from turning off when the number of beams interrupted is less than a preset number. The number that can be set is from 1 to 3 beams. This function enables sensing even when the position of the obstacles changes in the sensing area.

This Basic model of the type 4 safety light curtains provides the most important functions. Range reduction on the transmitter, reversible transmission channels, a LED display as well as an automatic start/restart interlock round out the range of service. The type 4 Basic model is suitable for a range of applications and is optionally available with AS-i interface or protection class IP 67/69K.

Advantages:
Automatic start/restart
Optimal handling
Prevention of mutual interference of the sensors by selectable transmission channels and range reduction, if applicable
Universal application due to standard functions
Short delivery times and global availability

Safety light curtains with integrated Muting functions. The Janus series is the solution for the protection of a vast number of high-risk industrial applications, in particular those requiring a high level of integration of the safety functions. For example, in the models with built-in Muting function, Janus guarantees the independence of the light curtain from the control circuits of the system (often distant from the protected gate) and, where necessary, also the integration of the Muting sensors. Settings of each function integrally performed via themain connector.
