cegard/Smart
Besides object detection, the cegard/ Smart light curtain
measures acceleration and distance data. This data is
communicated to the cegard/Smart control unit, where it
is processed further.

Installation
6.6.1 General instructions and precautions
Never scratch or paint the optical windows 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!
Chemicals can damage the profile and optical
characteristic. Contact with chemicalsmust be avoided
at all times!

Although the cegard/Smart system is insensitive to
direct sunlight, avoid unnecessary exposure, when
possible, especially the receiver unit.
Avoid interference from blinking / strobe lights or
infrared light sources such as photocells, infrared
security cameras or other light curtains.
Do not install the cegard/Smart 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.

Due to the nature of door system designs, (which as
complete systems are not failsafe), in extremely rare
conditions doors can close even when an obstacle is
present. Therefore, there must be, by code, other safety
means to prevent passengers 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 cegard/Smart system (as well as all other door
protection systems on the market) cannot – by its nature
– provide absolute safety for elevator passengers
passing through the door-way. It must not be used as
the final fail-safe device of the door mechanism. This
ultimate safety function has to be provided by a fail-safe
force and kinetic energy limiter.
CAUTION
Damage to the eye
Although the cegard/Smart 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.
6.7
Alignment
The optical axis of the emitter and the receiver edge need
to be aligned towards each other to ensure the light curtain
functions reliably.

The product labels are oriented towards the lobby area.
Reflective surface
Tx
Reflective surfaces near to or parallel to the detection zone
can cause reflections. Although the cegard/Smart is very
robust against such reflections, it is always advisable to
keep a reasonable distance between the sensor edges and
any reflective surfaces.
