3 Introduction
The easygard100 light curtain systems are opto-elec-
tronic devices that are used to detect objects or per-
sons in the vicinity of elevator doors.
The easygard100 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 suita-
ble for dynamic as well as static installations.
This document contains the technical specifications of
the easygard100 light curtain and the installation pro-
cedure.
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.

3.4 General operation
The easygard100 light curtain systems are supplied
as a pair with a transmitter (Tx) and receiver (Rx)
edge and two connection cables. The edges are built
with powder coated aluminum profiles. The transmit-
ter projects an array of infrared light beams to the re-
ceiver which consists of a number of photoelectric
cells. The beam pattern of the light curtain is sche-
matically displayed in Figure 3. Interruption of one or
multiple infrared beams triggers the output to change
state. Once the detection field is clear again, the out-
put changes state again to indicate that the area is
"clear
Each easygard100 system is equipped with an output
which is connected to the elevator control. Depending
on model, this output can either be a PNP or a NPN
output with a DO (dark on) or LO (light on) logic.
During door closing, when the distance between
emitter and receiver edges is decreasing the ±2 an-
gled beams are turned off. Table 1 provides the min-
imum and maximum number of beams for different
easygard100 systems:

4 Installation
4.1 General instructions and precautions
Never scratch or paint the optical windows be-
cause they form the light path! Do not drill addi-
tional 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 4: Installation hints
Although the easygard100 system is insensitive
to direct sunlight, avoid unnecessary exposure
when possible, especially the receiver unit (Fig-
ure 4).
Avoid interference from blinking lights or infrared
light sources such as photocells or other light
curtains.
Do not install the easygard100 system 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
4).
Due to the nature of door system designs, (which
as complete systems is not fail safe), in ex-
tremely rare conditions doors can close even
with an obstacle present. Therefore, there must
be, by code, other safety means to prevent pas-
sengers from being hurt by the elevator doors.
These dangerous situations should and can be
detected by the elevator control, which should, in
such a case, take the elevator out of service.
The easygard100 system (as well as all other
door protection systems on the market) cannot
by its nature provide absolute safety for eleva-
tor passengers passing through the doorway. It
must not be used as the final fail safe device of
the door mechanism. This ultimate safety func-
tion has to be provided by a fail safe force and
kinetic energy limiter.
CAUTION
Damage to the eye
Although the easygard100 light curtain does not
emit dangerous amounts of infrared light, long ex-
posure to intense infrared light sources can result
in damage to the eyes.
Never look directly into the active infrared
emitter from a close distance.
4.2 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.
Tx Rx

Figure 5: Alignment easygard100
The product labels are oriented towards the lobby
area.
Figure 6: Reflective surfaces
Reflective surfaces near to or parallel to the safe-
guarded area can cause reflections. Although the
easygard100 is very robust against such reflections,
it is always advisable to keep a reasonable distance
between the sensor edges and any reflective sur-
face.
4.3 Mechanical installation
WARNING
Electrical and mechanical
Hazards
Electrical shock and unexpected movement of the
protected application can cause serious injury or
death.
Switch off main power to the elevator
control system and mark clearly that the
elevator is out of service.
Follow all applicable safety measures.
Make sure that your installation complies
with all applicable regulations and safety
measures..
NOTICE
Mechanical damage to the
easygard100 light curtain
Do not drill additional holes into the light
curtain.
Do not overtighten the mounting screws.
Mount the edges on a flat surface
Do not bend the edges during transport or
during the installation.
Important:
1.1
Lowest beam
25 mm
32 Elements: 9 mm
36 Elements: 6 mm
Receiver and

to mount at
the same
height and
both connect-
ors are on

EN81-20:
Lowest beam
should be at
25mm above
entrance
level.
1.2
Check the
alignment of
the edges.
The receiver
needs to be
mounted 180°
to the emitter.
Important:
Make sure
the optical
windows are
facing each
other.
1.3

tions.

Connect the

edge and
guide the ca-
ble to the

7
Make sure the detection area between the
edges is not interrupted by door wings, ca-
bles, etc.
Guide the connection cables using appropri-
ate mounting material, e.g. cable protection
tubes, neoprene cable ties or cable guide
wires depending on the type of mounting kit
used. Improperly fixed and guided cables can
reduce cable lifetime drastically
Table 2: Mounting steps
NOTICE
Ensure that the cable bending radius is
greater than 80 mm when cables are
mounted.
If the cables are not properly fixed and
guided, their lifetime could be reduced
drastically. They can also be damaged due
to possible swinging and snagging in the
hoist way! Always follow the cable guide
instructions carefully, which can be found
in the appropriate mounting kit installation
and operation manual.
It is very important to install cables properly
to ensure the highest possible reliability
and lifespan of the light curtain. A properly
installed cable will withstand more than 20
million door movements, while a poorly
installed cable could break after less than
100,000 door movements.
4.4 Installation according to EN 81-20
To be compliant to the international standard EN81-
20 the light curtain must be installed so that the lowest
beam (bottom end) is positioned less than 25 mm
above floor (Figure 7).

5.3 Power-up
After installation (chapter 4):
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 easygard100 light curtain:
- For EN 81-20: use a none transparent test object
with a diameter stated in the code: Ø50mm. The
easygard100 light curtain must signal object de-
tected at all times during this test (from the bot-
tom to the top of the protective field).
