single safety beam EU2K

Function description

The EU2K system consists of a light transmitter and a light receiver. The transmitter transmits invisible, infrared chopped light.

The receiver consists of an optic for beam focusing and a secondary amplifier. A carrier frequency generator creates a second fixed frequency which is modulated with the transmitter frequency. Upon interruption of the protective field, the signal is interrupted. The switch position is indicated by an LED.

The assessment Elektronik built into the receiver creates two antivalent signals which are led to a sequential safety circuit consisting of four contactors only. In addition, all Fiessler LSUW control-units offered or a safe PLC can be used.

Field of application

The single-beam photo-electric safe control described here in fulfills the highest safety regulations. (Safety class 4 i.a.w. EN 954). An EEC prototype certification i.a.w. with the guidelines 89/329/EWG; 91/368/EWG, appendix VI, was issued by TÜV Rheinland.
