Changing the output logic
Output (PNP/NPN) logic is set using the gray wire.
The default logic is LO (light-on)(See
Timing Dia-
gram
, p. 11).
The default logic is LO if the gray wire is connected
to GND (0 V). Connecting the gray wire to USP (10
to 30 VDC) changes the output logic to DO (dark-
on) (See
Figure 11, Figure 12
and
Figure 13
)

OSE Output
The OSE is a 1 kHz safety output allowing for mon-
itoring according to EN ISO 13849-1:2008, without
using a test signal. For the OSE version the test in-
put of the light curtain has to be connected to supply
voltage.
As long as the monitored area is free, the OSE out-
put 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 fre-
quency starts again (See
Timing Diagram
, p. 11).
Test Input
To fulfill EN ISO 13849-1:2008, the RAY-LG with
PNP/NPN output must be tested by the door con-
troller before each door closing cycle. The RAY-LG
is available with test active LOW and on request
with test active HIGH (see
Product Description, p.
3
). Important: When the OSE output is used, using
the test input is not necessary to achieve monitoring
according to EN ISO 13849-1:2008.
Example:
Test active LOW (L)
When the test input switches to LOW, the RAY-LG
output switches after test response time t4. When
the test switches back to HIGH, the RAY-LG output
also switches back within restart time t5 and the test
sequence is successfully completed (See
Timing
Diagram
, p. 11).
