4 Introduction
The cegard/Pro (CabSafe 2D) light curtain systems
are opto-electronic devices that are used to detect ob-
jects or persons in the vicinity of elevator doors.
The cegard/Pro (CabSafe 2D) light curtain system
were designed and developed to be used in combina-
tion with the CEDES Cabsafe 3D sensor and
CabSafe Controllers (see CEDES user manual: 115
944) to fulfill the requirements of the US/Canadian
standard: ASME A17.1-2019 / CSA B44:19. For a cor-
rect function of the complete CabSafe System, only
light curtain components described in this document
shall be used. A connected CabSafe Controller tests
the function as well as detects the signals from the
entrance area sensor and the light curtain together.
Depending on an internal sequencing, it either holds
the door open, allows it to reverse or allows it to close
despite an occupied 3D entrance area sensor if none
enters or leaves the elevator cab.
The cegard/Pro (CabSafe 2D) light curtain system is
designed for and can be used in center-opening as
well as left or right side-opening elevator applications
and is suitable for dynamic as well as static installa-
tions.
This documentcontains the technical specifications of
the cegard/Pro (CabSafe 2D) light curtain and their
installation procedure.
A cegard/Pro (CabSafe 2D) light curtain system can
also be used in applications which have to fulfill the
European requirements of EN 81-20. In such applica-
tions the cegard/Pro (CabSafe 2D) light curtain sys-
tem can be used without the CabSafe 3D sensor and
CabSafe Controller.
In general, door protection systems do not provide ab-
solute safety for elevator passengers passing through
the doorway. They cannot be used as fail-safe de-
vices of the door mechanism. This safety function
must be provided by other means.
4.1 Light curtain system applications
Figure 2 shows the principal of the CabSafe system
architecture. The cegard/Pro (CabSafe 2D)
transmitter (Tx) and receiver (Rx) as well as the
CabSafe 3D sensor are connected to the CabSafe
Controller.

Controller and CabSafe 3D sensor. Such an
architecture is only allowed for applications which
require no detection of approaching passengers
according to ASME A17.1-2019 / CSA B44:19.
4.2 General operation
The cegard/Pro (CabSafe 2D) light curtain systems
are supplied as a pair with a transmitter (Tx) and re-
ceiver (Rx) edge and two connection cables. The
edges are built with anodized aluminum profiles. The

cegard/Pro CabSafe 2D Light Curtain English
© CEDES | V 1.0 CEDESAG reserves the right to modify or change technical data without prior notice. 5/14
transmitter projects an array of infrared light beams to
the receiver which consists of a number of photoelec-
tric cells. The beam pattern of the light curtain is dis-
played in Figure 6. Interruption of one or multiple in-
frared beams triggers the output to change state (sig-
naling an object is present in the detection field to the
upstream CabSafe Controller). Once the detection
field is clear again, the output changes state again to
indicate that the area is "clear”.
The light beams emitted from the transmitter are se-
quenced, one after the other, and pulsed at a specific
frequency. The receiver is designed to only accept the
specific pulse and frequency from its dedicated trans-
mitter. This enables the rejection of ambient light and
thus enhances their robustness in various environ-
ments.
Each cegard/Pro (CabSafe 2D) system is equipped
with two different output types:
- Push-Pull output; and
- “Frequency Safety Signal Low-output” (= FSSL-
output), a pulsed signal that is operated with a
maximum frequency of 1.8 kHz. The output fre-
quency changes with the distance between the
emitter and receiver edge allowing for dynamic
installations to rely on the cegard/Pro (CabSafe
2D) light curtain to indicate to the CabSafe Con-
troller that the door is closing or opening.
Which output type is active depends on the wiring
(connection of the white wire, see chapter 4.6.4).
4.3 Features
·Large operating range
·LED indication
·IP65 enclosure rating
·Frequency safety signal output (FSSL)
·Push-pull output
·Integrated distance recognition (used in a
CabSafe System)
·Easy alignment
·Front and side mounting holes implemented
·Slim design of only 12 mm × 16 mm (0.47 in.
x 0.63 in.)
4.4 General instructions and precautions
►Never scratch or paint the optical diodes or ele-
ments because they form 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
be avoided at all times!
►Chemical can damage the profile and optical
characteristic. Contact must be avoided at all
times!
Figure 3: Installation hints
►Although the cegard/Pro (CabSafe 2D) system is
insensitive to direct sunlight, avoid unnecessary
exposure when possible, especially the receiver
unit (Figure 3).
►Avoid interference from blinking lights or infrared
light sources such as photocells or other light
curtains.
►Do not install the cegard/Pro (CabSafe 2D) sys-
tem in places where the emitter and receiver
edges are directly exposed to light sources such
as fluorescent tubes or energy saving lamps.
►Make sure to orient the connection plugs for both
the emitter and receiver at the same end (Figure
3).
CAUTION
Damage to the eye
Although the cegard/Pro (CabSafe 2D) light curtain
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.

4.5 Integration
The following precautions must be followed when the
cegard/Pro (CabSafe 2D) light curtain is integrated
into a CabSafe System:
- The cegard/Pro (CabSafe 2D) light curtain must
be connected to the CabSafe Controller (see
user manual “CabSafe 3D sensor and CabSafe
Controller”).
- For static installations of the cegard/Pro
(CabSafe 2D) light curtain, a door position signal
has to be provided that informs the CabSafe
Controller about the door position (signal from
the elevator control or from a sensor).
- The max. door speed shall not exceed 0.5 m/s
(1.64 ft/s).
4.6 Installation
4.6.1 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.
4.6.2 Mechanical installation
WARNING

Table 1: Mounting steps
4.6.2.1 Installation height
To be compliant to the code the light curtain must be
installed so that the lowest beam (bottom end) is po-
sitioned ≤25 mm (0.984 in.) above floor (Figure 4).

Figure 4: Installation height cegard/Pro CabSafe 2D light curtain
4.6.2.2 Horizontal positioning
For dynamic installations, when the light curtain is in-
stalled at the doors, the cegard/Pro (CabSafe 2D)
light curtain can be used to inform the CabSafe Con-
troller about the distance of the light curtain. The fre-
quency of the FSSL output changes depending on the
distance of the emitter and receiver edge (see chapter
4.7).
Important for installations in a CabSafe system: for a
reliable detection of the door closing/opening is, that
the light curtain edges have a distance “A”
- less than 100 mm (3.94 in.)
- but more than 10 mm (0.394 in.)
when the door is in the fully closed position (Figure 5).

4.6.2.3 Mounting according to EN 81-20
EN 81-20 requires a detection capability of 50 mm
(1.97 in.) up to a height of 1’600 mm (5.25 ft.) of the
door opening. The cegard/Pro CabSafe 2D light
curtain with 36 elements achieves a 50 mm (1.97 in.)
resolution even at a distance of minimum „10 mm“
(0.39 in.) between the two edges for both: dynamic
and static installations.

4.6.4 Output
When an object enters the safeguarded area (OB-
JECT DETECTED) thecegard/Pro (CabSafe 2D) light
curtain output changes state after response time t2
(see Figure 12). When the object leaves the safe-
guarded area (NO OBJECT) the cegard/Pro
(CabSafe 2D) light curtain output switches back after
release time t3 (see Figure 12).
The output logic of the cegard/Pro (CabSafe 2D) is
set using the gray wire. The logic will be defined by
the power-up sequence. After the power up the logic
will not change until the next power-up is made. The
default logic is Light ON (LO) (which is shown in Fig-
ure 12). The output logic is LO if the gray wire is con-
nected to GND (0 V). Connecting the gray wire to USP
changes the output logic to Dark ON (DO).
If the gray wire is not connected (floated), the output
logic changes to the FSSL output signal (see chapter
4.6.4.1).

4.6.4.1 FSSL output
The FSSL (Frequency Safety Signal Low) output is a
frequency safety output signal allowing for safeguard-
ing. As long as the safeguarded area is free, the FSSL
output sends a pulsed signal. The frequency depends
on the distance between the Tx and the Rx edge (see
chapter 4.16.4).
The default logic is Light ON (LO) (Figure 9). When
an object enters the safeguarded area (OBJECT DE-
TECTED), the FSSL output switches to LOW/GND (0
V). When the object leaves the safeguarded area (NO
OBJECT) the frequency starts again.

The output type of the cegard/Pro (CabSafe 2D) light
curtain can be configured with the gray wire. For the
connection of the cegard/Pro CabSafe 2D light curtain
to the CabSafe controller the output must be set to
FSSL functionality (gray wire floated). For applica-
tions without the CabSafe controller (see Figure 2) the
output can be set to a typical Push-Pull functionality.

4.8 Start-up
After installation (chapter 4.6):
1. Switch on mains and power-up the elevator con-
trol unit. The LED on the receiver edge blinks
during the start-up phase.
2. Check the LED on both edges (power, status).
3. Test if the system is working correctly by inter-
rupting the cegard/Pro CabSafe 2D light curtain:
- For ASME A17.1-2019 / CSA B44:19 use a non
transparent test object with the dimensions
stated in the code: 80 mm (3.15 in.) above floor
level and 50mm (1.97 in.) at floor level. The ce-
gard/Pro CabSafe 2D light curtain as well as the
CabSafe Controller must signal object detected
at all times during this test.
- For EN 81-20: use a non transparent test object
with the dimensions stated in the code: 50mm
(1.97 in.) The cegard/Pro CabSafe 2D light cur-
tain as well as the CabSafe Controller must sig-
nal object detected at all times during this test
(from the bottom to the top of the protective field).

4.11 Maintenance
Although the cegard/Pro (CabSafe 2D) Light Curtain
does not need regular maintenance, a periodic
functional check is strongly recommended:
►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.
►Check the detection behavior of the
cegard/Pro (CabSafe 2D) light curtain
according to the requirements of local
regulations.
NOTICE
Damage to the optical elements
►Never use any solvents, cleaners or mechan-
ically abrasive towels or high-pressure water
to clean the sensor.
►Avoid scratching the optical elements while
cleaning.
4.12 Product label
Each cegard/Pro CabSafe 2D light curtain edge is
