AS-Interface light curtains and light arrays for Category 4

■Overview

 

■Benefits

 

 

• Double-scan function

 

 

• Cascading of host and guest devices

 

 

• Two transmission channels

 

 

 

 

■Design

 

 

A SIGUARD Light Curtain or light array comprises a transmitter

 

 

and a receiver that must be mounted opposite each other.

 

 

Depending on the resolution and length, a specific number of

 

 

transmit and receive diodes are arranged in a vertical row.

 

 

The infra-red LEDs of the transmitter send short light pulses that

 

 

are received by the receive diodes.

 

 

SIGUARD Light Curtains:

 

 

• Resolution 14, 30 and 50 mm,

 

 

• Length 150 mm to 3 m,

 

 

• Cascading of master and slave devices to create larger height

 

 

or length of protective zone or for angular arrangement.

 

 

SIGUARD Light Arrays:

 

 

• 2-, 3- or 4-beam for access protection.

The light curtains and light arrays of Category 4 acc. to EN 954- 1 offer active optical protection for persons at machines. They can be connected to AS-Interface directly and safely as an op- tion.

SIGUARD light curtains and light arrays are

•active opto-electronic protective devices (AOPD),

•comply with Type 4 acc. to EN 61496-1, -2,

•are EU prototype-tested,

•protect the operating personel working on or near dangerous machines,

•operate contact-free,

•are free of wear in comparison to mechanical systems (e.g. safety mats).

For further details, see the manual "Safety Integrated“ and the operating instructions for the respective devices.

Standards

•EN 61 496-1, -2, IEC 61 496-1, -2 (requirements for non-contact protection systems)

•EN 999 (incl. calculation of safety clearances)

• EN 954-1 (safety of machines, safety-related parts of controls).
