Product and Applications Description
Dusk sensor
The dusk sensor has the task of converting the current
light intensity at dusk into a corresponding electrical
signal. This electrical signal is detected by the central
controller and compared with the set dusk threshold
values. If the value falls below this limit, blinds can be
lowered for example or the exterior light can be
switched on.
Installation
The dusk sensor is mounted vertically on the mast
fixing provided. Due to the angle of illumination, the
device should be mounted so that the Siemens label is
located at the front of the device. The dusk sensor
should be aligned northwards. To ensure the faultless
recording of measured values, the sensor must not lie
in the shadow of a building or tree during the course of
the day.
Temperature sensor
The temperature sensor has the task of converting the
current external temperature into a corresponding elec-
trical signal. This electrical signal is detected by the
central controller and compared with the set tempera-
ture threshold values. The primary task of the tempera-
ture sensor is to protect the awning from frost damage.
Installation
The temperature sensor is installed in a location that is
protected from direct sunlight. Ideal locations are under
the eaves but not in areas where warm air can accumu-
late.

Light sensor
The light sensor has the task of converting the current
light intensity into a corresponding electrical signal. This
electrical signal is detected by the central controller and
compared with the set light threshold values.
If the light intensity is too high, the awning is lowered,
so that the lighting conditions inside the building are
improved and the rooms do not start to warm up.
Installation
The light sensor is installed vertically on the mast
mounting provided. Due to the angle of illumination, the
device should be mounted so that the Siemens label is
located at the front of the device. The light sensor must
be aligned so that its surface points in the direction of
the façade that the sensor is controlling. To guarantee
the faultless recording of measured values, the sensor
should not lie in the shadow of a building or tree during
the course of the day.
Rain sensor
During rainfall, the raindrops create a conductive con-
nection between the electrodes on the surface of the
sensor and thus trigger a switching signal which is
evaluated by the central controller. An output voltage of
approx. 1 V corresponds to “no rain” while 9 V signifies
rain.
The surface of the sensor is heated in 2 stages. The
first heating level is continually switched on and pre-
vents dew and ice from forming. The second level is
switched on for the duration of the rain shower and
ensures that the surface is dried quickly.
Cleaning
Due to pollutants in the atmosphere, a layer of dirt
gradually forms on the surface of the sensor which can
lead to insulation or short circuits. The rainfall can then
no longer trigger the correct signal. Maintenance is
therefore required on the sensor. The surface must be
regularly cleaned with a mild cleaning agent while en-
suring that no damage is caused to the sensor.
The connection is carried out on a 5 metre long, 3-core
connection cable. The colours of the cores for the
measuring signal are white (+15 V), green (sensor
signal) and brown (GND). They are positioned accord-
ing to the wiring plans of the control devices.
Installation
The rain sensor is fixed to the mast using a mounting
bracket (e.g. with a clip, max. 22 mm wide, not supplied
with the device) or to a wall of the house in a westerly
direction. The device should be aligned so that it is
continually exposed to rainfall.

Wind sensor generally 5WG1 258-7ABxx
Function
The wind sensor has the task of converting the current
wind speed into a corresponding electrical signal. This
signal is detected by the central controller and com-
pared with the set threshold values for the wind. If this
value exceeds the limit value, the awning is retracted
for example to protect the sun blinds from damage.
The wind sensor is equipped with a function monitoring.
In case of a fault in one of the wind sensors (bearing
damage, interruption in voltage to the heating trans-
former or the signal line) the fault will be automatically
signaled after 60 hours and the safety objects linked to
the wind speed will be triggered.
The controller must only ever be reset once the fault
has been remedied (replacement of the wind sensor or
the wing).
To reset, switch off the 230V voltage supply to the
weather central controller and the heating transformer
for at least 10 minutes.
Installation
! The connection cables between the central device
and the sensor should not exceed 20 m.
! The wind sensor may not be mounted in the slip-
streams of a building (e.g. chimney, lift shaft).
! There are two different fixing options available when
installing the wind sensor:
- The base of the wind sensor is designed for inser-
tion into a mast pipe (inner diameter = 36mm).
The mast must be connected to lightning protec-
tion or must be connected to earth ground.
- To mount the wind sensor on a wall a bracket arm
is required
Note
Screw of the wind wing (wind sensor heated) is sealed.
When unscrewing goes out the IP 65 protection!
especially Wind sensor heated 5WG1 258-7AB02
Function
This wind sensor has a wing-breakage-detection. In
case of wing breakage (pendulum movement 5x that of
the wing) a 100 km/h signal is issued immediately,
which likewise triggers the safety objects linked to the
wind speed.
Connection
The connection of the wind sensor is carried out on a 5
meter long, 4-core connection cable. The colours for
the measuring signal is white (sensor signal) and brown
(GND).
The colours of green and yellow are intended for the
connection of the heating transformer. They are con-
nected according to the wiring plan (in the cover of the
heating transformer for wind.
Installation
The Wind sensor heated 5WG1 258-7AB02 (with wing-
breakage-detection) must not be installed at a facade,
or near thermal lifts. The wind sensor must be installed
using a mast, 1.5m beyond the roof.
Note

transformer

(GND) and green ( + 12-24V DC ).
