2 Safety Notes

The light barrier system corresponds to the
directive for electromagnetic compatibility
89/336/EEC.
For cleaning the housing do not use
strong detergents or chemicals.
Do not operate the light barrier system at
extreme temperature ranges (admissible
ambient temperature range: -25 °C to
+55 °C).
If the light barrier system is used for other
purposes than originally intended, if it is
not installed in the correct way or not
repaired by skilled personnel, no liability
for any damage will be accepted.
If the light barrier system is to be put out
of operation permanently, take it to a
local recycling plant for disposal.

3 Applications

The infrared light barrier system is suitable
both for indoor and outdoor use (IP 44). It
can be used e. g. in alarm systems and
control devices or counting devices. The
indoor operating range is 100 m, the out-
door operating range is 50 m.
The light barrier system works with two
parallel infrared beams. An alarm is trig-
gered if both beams are simultaneously
interrupted. Thus, a high reliability is ob-
tained and the risk of false alarm is mini-
mized.
4 Installation
Installation should only be performed by
skilled personnel.
4.1 Mounting
To prevent malfunctions or false alarms,
please observe the following items when
choosing a mounting location:
The distance between transmitter and
receiver must not exceed 100 m indoors
or 50 m outdoors.
The transmitter and the receiver can be
adjusted in the housing horizontally by
±90° and vertically by ±5°. However, the
best adjustment is obtained when the
housings directly face each other.
Avoid direct sunlight on the sensor of the
receiver. If shading is impossible, mount
the transmitter facing the sun.
Do not mount the light barrier system at a
location
1. where the housing may be splashed
with water or dirt,
2. where sudden bright light may occur,
e. g. headlights of a passing car,
3. where animals may interrupt the IR
beam,
4. where leaves from trees or bushes
may be blown into the IR beam.
If two light barrier systems are mounted
in parallel, do not mount the transmitters
on the same side but on opposite sides.
Otherwise interferences
which cause malfunctions.
Mount the transmitter and the receiver at a
suitable location where they are facing
each other on the same level:
