Product Description
The RAY-LG is a very reliable SIL 2 certified safety
light curtain. It was developed and designed to
safeguard all types of vertically opening industrial
doors such as sectional or highspeed doors. The
system is ideal for door openings up to 10 m width
and can handle door closure speed of 1.6 m/s. The
opening speed is up to 3 m/s. The emitter and
receiver are preferably installed directly inside the
guide rail. The RAY-LG has a selectable transistor
(NPN/PNP) or OSE output, so one system can
handle all relevant outputs. Selecting the OSE
output allows operation according to EN ISO
13849-1:2015 Cat. 2 without periodic testing of the
light curtain. This output is included in the TÜV
certification of the RAY-LG.
Functionality
The emitter and receiver edges create a grid of
infrared beams offering up to 2.5 m (8.2 ft) in
protection height.
When the infrared beams are interrupted, the
output sends a signal to the connected door
control unit. As soon as the detection area is clear
again, the output switches to indicate that the area
is "clear". The blanking system is designed to
mount directly into the guide rails. As the door
closes, the RAY-LG recognizes the door as such
and does not switch the output.
Once the door has arrived at the fully closed
position, the output signal will be switched off.
Intended use
RAY-LG is certified according to
EN ISO 13849-1:2015 and EN 12978:2009 if the
door is monitored over its full height up to 2.5 m
(8.2ft). It is designed and approved for mounting
and use in- and outside the side guides of
industrial doors and serves as E-device presence
detection according to EN 12978:2009 and
EN 12453:2017.
The RAY-LG 35XX fulfills the safety level up to
SIL 2 according to EN 61508:2010 and the
category 2 (cat. 2) / performance level d (PL d)
according to EN ISO 13849-1:2015.

Type Key
RAY-LG A B CD
A: Output
B: Aperture Angle
CD: Number of Optical Elements
A= 3: Semiconductor/OSE
B= 5: ±5°
CD = 20: 20 Elements (2060 mm)
CD = 22: 22 Elements (2420 mm)
Alignment and Calibration
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 functions. Keep a reasonable
distance between the sensor edges and any reflective surface.
A self-calibration on each optical beam is implemented. At the power- up
the ideal emitting strength will be detected and used. To reduce
interruption caused of dust the system checks the emitting power and
adapt a new higher or lower strength if necessary. After 45 s interruption
a self-reset of the system will be made.
CAUTION:
Damage to the Eye
Although the RAY-LG does not emit dangerous amounts of infrared light, long exposure to intense infrared light
sources can result in damage 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

Application Overview
Door Blanking
The RAY-LG can differentiate between a light beam interruption caused by an object and a light beam
interruption caused by the closing door. The RAY-LG does this by analyzing the different interruption
patterns.
Blanking Routine during Door Closure:
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 inside or, in this case matching holes need to be drilled, behind the side
guide, the door moves directly in front of the light curtain. The bottom section of the door needs to be solid
for at least 30 mm over the entire door width to ensure that at least one light element is completely
covered. Hollow extrusion profile may need to get clogged.

When the installation of RAY-LG is not possible inside the side guide, it may also be mounted from the
back side (Figure 5.1). Holes of min Ø 10 mm must be drilled into the profile to allow the light to pass
through.
If two light curtains are installed parallel to, but not in line with the door panel in front of and behind the
guide rail, the descending door will not interrupt the active beams. (Figure 5.2) However, blanking may still
be required if any obstructing part of the door (e.g. strengthening bars, hinges, junction boxes) interrupt the
light curtain. A beam blocker can be employed to shade the diodes on one side, but it must be mounted so
that at least one element is continuously covered during door closure (Figure 5.2).
3 seconds after the last beam was interrupted by the now closed door, the output signal is interrupted.

RAY-LG 35XX
Page 7 RAY-LG 35XX Version: 1.0
Blanking Routine during Door Opening / Partial Opening Function
The output signal will remain off during the opening of the door until the 11th beam is unobstructed (approx.
500 mm opening height). From this position onwards it will be possible to reverse and close the door in
automatic mode. Successively releasing additional light beams will increase this partial opening position
accordingly. During a later closing cycle, the monitored area and the smart blanking function will be limited
to the previously saved partial opening height, higher positioned light beams will remain blanked.
When the power supply of the RAY-LG is interrupted in a partial opening position, it is necessary to open
the door higher than the safeguarded area to allow the system to undergo an automatic initialization
routine.
Installation
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
▪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
installation in order to avoid damage.
▪Do not bend or twist the edges!
▪Oil can damage the cables. Contamination must
always be avoided!
▪Chemical can damage the profile and optical
characteristics. Contact must always be avoided!
NOTICE:
Mechanical Damage to the RAY-LG
▪Do not drill additional holes into the light curtain
▪Do not drill through mounting holes
▪Do not over-tighten the mounting screws

▪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 photocells 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.
1. Switch off main power to the door control unit
and clearly mark that this system is out of
service before performing any work on the
system.
2. Mount the receiver on one side of the door
with better access to Door control unit for
easier cabling and only use the mounting
holes provided on the sensor bars (See
Figure 6.2).
3. In case of severe disturbances or direct
sunlight mount the receiver on the opposite
side
4. Mount the receiver bar into the guiding track
next to the door control unit (See Figure 5.1).
In order to fulfill EN 12978:2009 the lower end
of the edges must be at the level of the door
closed position (See Figure 6.1).
5. Mount the emitter across from the receiver. If
the receiver is mounted in the guiding track,
the emitter should be mounted in the guiding
track opposite the receiver. Make sure the
optical elements are facing each other (See
Figure 6.1).
6. Connect the emitter with the receiver using
the synchronization cable.
7. Plug the connection cable into the blue plug
on the receiver bar and connect it to the door
controller (See Electrical Connection, p. 9).
8. If using two RAY-LG on sides of the slide
guide rail (See figure 5.2) make sure that
both receiver bars are not mounted on the
same side of the door to avoid interference
between two sets.

Changing the output logic
Output (PNP/NPN) logic is set using the gray wire.
The default logic is LO (light-on) (See Timing
Diagram, p. 11).
The output 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 9). If the gray wire is not
connected (floated), the output logic changes to
the OSE signal.

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.
