The light curtain correspond to the highest safety regulations:
Safety Integrity Level SIL 1 (IEC 61508) 
Performance Level PL c (ISO 13849-1)
Safety category cat. 2 (EN 954-1)

Function description

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.

Operating mode

The operating mode with contactor control serves for monitoring the triggered follow-up contactors.
After each interruption of the optical path and before each release of the switching outputs the follow-up contaction are checked whether they dropped. If the contactors don´t dropped with in 300ms the light curtain output contacts go into lock status.

If the operating mode with restart control is adjusted, a push-button must be connected for the start release of the working movement.
With a free protection field the yellow LED lights up. After actuating the start push-button the two outputs of the TLVT are activ.

During the operational mode equivalent outputs both PNP outputs and provide short-circuit- and side-current passages monitoring.

With free optical path both outputs are high(+24V). During the operational mode antivalent outputs, output No. 1 is high (+24V) and output No. 2 low (0V), with free optical path.
