3 Description
Wind Sensor KNX W • Date of issue: 31.10.2012 • Technical changes reserved. Errors reserved.
1. Description
The Wind Sensor KNX W measures wind speed and transfers the values to the KNX
system. Three switching outputs with adjustable threshold values as well as additional
AND and OR logic gates are available.The sensor system, the evaluation electronics
and the electronics of the bus connection are mounted in a compact housing.
Functions:
•Wind measurement: The wind strength measurement takes place
electronically and thus noiselessly and reliably, even during hail, snow and
sub-zero temperatures. Even turbulent air and anabatic winds in the vicinity of
the weather station are recorded
•3 switching outputs with adjustable threshold values (Threshold values can
be set by parameter or via communication objects)
•8 AND and 8 OR logic gates with each 4 inputs. Every switching incident as
well as 8 logic inputs (in the form of communication objects) may be used as
inputs for the logic gates. The output of each gate may optionally be configured
as 1 bit or 2 x 8 bits
Configuration is made using the KNX software ETS. The programme file (format VD),
the data sheet and the manual can be downloaded from the Elsner Elektronik
homepage on www.elsner-elektronik.de in the “Service” menu.

2. Installation and commissioning
2.1. Installation notes
Installation, testing, operational start-up and troubleshooting should
only be performed by an electrician.
DANGER!
Risk to life from live voltage (mains voltage)!
There are unprotected live components inside the device.
• National legal regulations are to be followed.
• Ensure that all lines to be assembled are free of voltage and take
precautions against accidental switching on.
• Do not use the device if it is damaged.
• Take the device or system out of service and secure it against
unintentional use, if it can be assumed, that risk-free operation is no
longer guaranteed.
The device is only to be used for its intended purpose. Any improper modification or
failure to follow the operating instructions voids any and all warranty and guarantee
claims.
Measurement range Wind 0...35 m/s
Resolution (wind) 0,1 m/s
Accuracy (wind) at ambient temperature -20…+50°C:
±22% of the measurement value when incident flow is
from 45…315°
±15% of the measurement value when incident flow is
from 90…270°
(Frontal incident flow corresponds to 180°)

5 Installation and commissioning
Wind Sensor KNX W • Date of issue: 31.10.2012 • Technical changes reserved. Errors reserved.
After unpacking the device, check it immediately for possible mechanical damage. If it
has been damaged in transport, inform the supplier immediately.
The device may only be used as a fixed-site installation; that means only when assem-
bled and after conclusion of all installation and operational start-up tasks and only in
the surroundings designated for it.
Elsner Elektronik is not liable for any changes in norms and standards which may occur
after publication of these operating instructions.
2.2. Location
Select an assembly location at the building where wind speed may be collected by the
sensor unobstructedly. At least 60 cm of free space must be left beneath the device to
enable correct wind measurement and prevent snowing in when there is snow. The
distance also protects the unit against damage by birds.
2.3. Mounting the sensor
2.3.1. Attaching the mount
The sensor comes with a combination wall/pole mount. The mount comes adhered by
adhesive strips to the rear side of the housing.
Fasten the mount vertically onto the wall or pole.
Fig. 1
The wind sensor must be mounted on a verti-
cal wall (or a pole).

2.3.3. Preparing the sensor
The sensor cover snaps in on the left and right along the bottom edge (see Fig.). The
cover of the 230V model is also screwed on top. Remove the cover. Proceed carefully,
so as not to pull off the wire connecting the PCB in the bottom part with the cover (sol-
dered cable connection in case of 230 V AC version, cable with plug in case of 24 V DC
version).
Lead the cable for the voltage supply and bus connection through the rubber seals on
the bottom of the device and connect Voltage L/N and Bus +/- to the terminals provid-
ed.
For 24V devices the connection cable must be plugged in between the cover and circuit
board.

11 Addressing of the device at the bus
Wind Sensor KNX W • Date of issue: 31.10.2012 • Technical changes reserved. Errors reserved.
DANGER!
There is a risk to life from the live voltage on a 230 V device!
• The cover must be screwed on in operation.
To remove it, the weather station can be simply pulled upwards out of the mount,
against the resistance of the fastening.
2.4. Notes on mounting and commissioning
Do not open the device if water (rain) might ingress: even some drops might damage
the electronic system.
Observe the correct connections. Incorrect connections may destroy the sensor or con-
nected electronic devices.
The measured wind value and thus all other wind switching outputs may only be sup-
plied 60 seconds after the supply voltage has been connected.
After the auxiliary voltage has been applied, the device will enter an initialisation phase
lasting a few seconds. During this phase no information can be received via the bus.
3. Addressing of the device at the bus
The device is supplied with the bus address 15.15.250. You can program another ad-
dress into the ETS by overwriting the 15.15.250 address or by teaching via the pro-
gramming key on the circuit board inside the housing.
Fig. 14
With the 230V model, screw the cover on to
the underpart, to prevent unauthorised or ac-
cidental opening.
Fig. 15
Push the housing from above into the fas-
tened mount. The bumps on the mount must
snap into the rails in the housing.

12 Maintenance
Wind Sensor KNX W • Date of issue: 31.10.2012 • Technical changes reserved. Errors reserved.
DANGER!
Risk to life from live voltage (mains voltage)!
• With the 230V model, bus addressing via the programming key
should only be done by an accredited electrician.
• Do not touch any components on the circuit board while pressing
the key.
4. Maintenance
DANGER!
There is a risk to life from the live voltage (mains voltage)!
If you come into contact with live components in the device, (e.g. caused
also by a jet of water) there is the risk of an electric shock with
230 V devices.
Risk of injury caused by components moved automatically!
Durch die Automatiksteuerung können Anlagenteile anlaufen und
Personen in Gefahr bringen (z. B. fahren Fenster/Markise wenn beim
Reingen Regen-/Windalarm ausgelöst wurde).
The automatic control can start system components and place people in
danger (e.g. moving windows/awnings if a rain/wind alarm has been
triggered while cleaning).
• Always isolate the device from the mains for servicing and cleaning
(e. g. switch off or remove the fuse).
The device must regularly be checked for dirt twice a year and cleaned if necessary. In
case of severe dirt, the sensor may not work properly anymore.
ATTENTION
The device can be damaged if significant volumes of water penetrate the
housing.
• Do not clean with high pressure cleaners or steam jets.
