The RAY-LG is a very compact, SIL 2 certified safety
light curtain, designed to monitor any type of auto-
matic door and gate. It has a maximum operating
range of 10 m (32.8 ft) and can handle door speeds
of up to 1.6 m/s (5.3 ft/s). The emitter and receiver
bars can be installed directly into the guide track
thanks to the automatic door blanking feature. In ad-
dition, the RAY-LG features the OSE Signal, allow-
ing operation according to EN ISO 13849-1:2008
Cat. 2 without periodic testing of the light curtain.
When using the optional version with PNP/NPN out-
put the system has to be tested periodically before
the door closing.
Figure 1: Typical RAY-LG application environments
Functionality
The emitter and receiver edges create a grid of in-
frared beams. When the infrared beams are inter-
rupted, the system outputs a signal to the con-
nected door controller. As soon as the detection
area is clear again, the output switches to indicate
that the area is “clear”. The blanking system is de-
signedtomountdirectlyintotheguidetracks.As the
doorcloses, the RAY-LG recognizes the door is not
an obstruction. The door blanking feature allows
partial closing of the door and subsequent continu-
ation of the closing cycle.

General Instruction and Precaution
▪Never scratch or paint the optical lenses because it
may obstruct the light path! Do not drill additional
holes into the profile. Unpack the profiles just before in-
stallation in order to avoid damage.
▪Do not bend or twist the edges!
▪Oil can damage the cables. Contamination must be
avoided at all times!

▪Although the RAY-LG is not sensitive to direct sunlight,
avoid all unnecessary exposure if possible, especially
to the receiver.
▪Avoid interference from blinking lights or infrared light
sources such as photo cells or other light curtains.
▪Do not install the RAY-LG in places where the emitter
and receiver edges are directly exposed to light
sources such as FL tubes or energy saving lamps.
▪Make sure to place the connection plugs for both the
emitter and receiver at the same end.
Alignment
The optical axis of the emitter (Tx) and the receiver edge
(Rx) need to be aligned towards each other to ensure the
light curtain functions reliably.
Reflective surfaces near to or parallel to the detection area
can cause reflections and interfere with the RAY-LG's func-
tions. Keep a reasonable distance between the sensor
edges and any reflective surface.
CAUTION
Damage to the Eye
Although the RAY-LG does not emit dangerous
amounts of infrared light, long exposure to in-
tense infrared light sources can result in dam-
age to the eyes.
- Never look directly into the active infrared
emitter from a close distance
Possible health risks - Disregarding these
warnings can result in injury

Door Blanking
The RAY-LG can differentiate between a light beam interruption caused by an object and a light beam inter-
ruption caused by the closing door. The RAY-LG does this by analyzing the different interruption patterns.
Closing door interruption pattern:
The light beam interruption of a closing door starts at the topmost beam going downwards. There are two
ways to achieve blanking:
When the RAY-LG is integrated into the guide rail,
the door moves directly in front of the light curtain.
This means the lowest section of the door needs to
be at least 30 mm in height to ensure that at least
one element is completely covered. It is also essen-
tial that the door's leading edge extends the full dis-
tance between the light curtain's emitter and re-
ceiver. (See figure 8.1)
If the light curtain is located either in front of or be-
hind the guide rail, the descending door will not in-
terrupt the active beams. However, blanking may
still be required if any part of the door (e.g. cable)
interrupts the light curtain. A beam blocker can be
used but it must be mounted so that at least one
element is continuously covered during door clo-
sure. (See figure 8.2)

Installation
1. Switch off main power to the door control unit
and clearly mark that this system is out of ser-
vice before performing any work on the system.
2. Mount the receiver edge on one side of the
door.
Important:
Mount the receiver edge into the guiding rail
next to the door control unit (See Figure 7).
The lower end of the edges has to be at the
level of the door closed position.
3. Mount the emitter edge across from the re-
ceiver edge. If the receiver is mounted in the
guiding rail, the emitter should be mounted in
the guiding rail opposite the receiver. Make
sure the optical elements are facing each other
(See Alignment, p. 5).
4. Connect the emitter with the receiver edge us-
ing the synchronization cable.
5. Plug the connection cable into the blue plug on
the receiver edge and connect it to the door
controller (See Electrical Connection, p. 9).
WARNING
Electrical and Mechanical Hazards
Electrical shock and unexpected door movement
can cause serious injury or death.
▪Follow all applicable safety measures
▪Use only specific and approved tools
▪If the RAY-LG must be adjusted, the main
power supply must be switched off and
marked as “out of service”.
Serious Health Risks - Disregarding these
warnings can result in serious injury or death.
NOTICE
Mechanical Damage to the RAY-LG
▪Do not drill additional holes into the light cur-
tain
▪Do not over-tighten the mounting screws
▪Mount the edges on a flat surface
▪Do not drill directly into the mounting holes
Risk of damage - Disregarding this notice can
lead to damage to the sensor, the door controller
and / or other devices

Electrical Connection

Important: Any unconnected (not used) wire must be separated and isolated.
For the PNP/NPN the test input is active low.
Figure 11: Connection diagram OSE output
Important: Any unconnected (not used) wire must be separated and isolated.
For the OSE version the test input of the light curtain has to be connected to supply voltage.
Output
When an obstruction is detected, (OBJECT
DETECTED) the RAY-LG output changes after re-
sponse time t2. When the object leaves the surveil-
lance area (NO OBJECT) the RAY-LG output
switches back after release time t3 (See Timing Di-
agram, p. 11)

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).

Maintenance
Although the RAY-LG does not need regular maintenance, a periodic functional check is strongly recom-
mended:
▪Make sure the optical elements are clear of dirt and dust. If necessary, clean the front surface with a
soft towel.
▪Make sure the edges are securely fastened.
▪Check the mounting position, cable routing, and connection of the sensor.
Disposal
Disposal should be done using the most up-to-date
recycling technology according to local regulations
and laws. There are no harmful materials used in
the design and manufacture of the sensor. Traces
of such dangerous materials may be found in the
electronic components but not in quantities that are
harmful.
NOTICE: Damage to the optical elements
▪Never use any solvents, cleaners or mechanically abrasive towels or high-pressure water to clean the
sensor
▪Avoid scratching the optical elements while cleaning
