  • integrated control-unit with contactor control and restart activatable by DIP switches activatable
  • contactor/valves directly connectablly, switching capacity 0,5A/24V
  • smallest safety distances by short response times 4,5ms to 24,5ms, depending of the protection high
  • smallest obstacle recognition of 14mm from 0,3m to 7m range
  • protection heights of 100mm to 1900mm in 100mm steps
  • microprocessor monitoring of the safety functions
  • built in selfdiagnostic with error display
  • muting and stroke operation with optional safety control-unit PLSG
  • protective system IP65

The light curtain correspond to the following safety regulations:
Safety Integrity Level SIL 3 (IEC 62061) 
Performance Level PL e (ISO 13849-1)
Safety category cat. 4 (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 ULVT are activ.

In the operating mode bivalent outputs both PNP outputs are errorproof and internally monitored on short circuit ad transverse. With free optical path, both outputs are high (+24V). In the operating mode antivalent outputs with free optical path output1 is high (+24V) and output2 is low (0V). Output2 is not error-proof in this operating mode. This operating mode is only allowed in connection with the control-units LSUW NSR 3-1K, LSUW N1-Muting K or another safe secondary control, which monitors the Output2!
