RAY-LG 35XX
Version: 1.0
OSE Output
The OSE is a 1 kHz safety output allowing for
monitoring according to EN ISO 13849-1:2015,
without using a test signal. For the OSE version
the test input (white cable) of the light curtain has
to be connected to supply voltage (brown cable).
As long as the monitored area is free, the OSE
output sends a 1 kHz signal. When an object
enters the monitored area (OBJECT DETECTED)
the OSE output switches to LOW/GND (0V). When
the object leaves the monitored area (NO
OBJECT) the frequency starts again (See Timing
Diagram, p. 11).
Test Input
To fulfill EN ISO 13849-1:2015, the RAY-LG with
PNP/NPN output must be tested by the door
controller before each door closing cycle. The
RAY-LG is available with test active LOW.
Important:
When the OSE output is used, using
the test input is not necessary to achieve
monitoring according to EN ISO 13849-1:2015. In
this case, the white wire must be connected to the
USP.
