3 Description

Wind Sensor KNX W • Status: 11.11.2021 • 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

•Wind sensor monitoring: If the wind measurement value changes by less

than ± 0.5 m/s within 48 hours, the maximum measurement value of 35 m/s is

output as a fault message. All wind alarms with a limit value below 35 m/s

become active as a result

•3 threshold values can be adjusted per 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 product file can be down-

loaded from the Elsner Elektronik website on www.elsner-elektronik.de in the “Ser-

vice” menu.

4 Installation and commissioning

Wind Sensor KNX W • Status: 11.11.2021 • Technical changes reserved. Errors reserved.

The product conforms with the provisions of EU directives

2. Installation and commissioning

Installation, testing, operational start-up and troubleshooting should

only be performed by an authorised electrician.

DANGER!

Risk to life from live voltage (mains voltage)!

There are unprotected live components inside the device.

• Inspect the device for damage before installation. Only put undamaged devic-

es into operation.

• Comply with the locally applicable directives, regulations and provisions for

electrical installation.

• Immediately take the device or system out of service and secure it against un-

intentional switch-on if risk-free operation is no longer guaranteed.

5 Installation and commissioning

Wind Sensor KNX W • Status: 11.11.2021 • Technical changes reserved. Errors reserved.

Use the device exclusively for building automation and observe the operating instruc-

tions. Improper use, modifications to the device or failure to observe the operating in-

structions will invalidate any warranty or guarantee claims.

Operate the device only as a fixed-site installation, i.e. only in assembled condition and

after conclusion of all installation and operational start-up tasks, and only in the sur-

roundings designated for it.

Elsner Elektronik is not liable for any changes in norms and standards which may occur

after publication of these operating instructions.

2.1. Location

Select an assembly location at the building where wind speed may be collected by the

sensor unobstructedly.

At least 60 cm of clearance must be left all round the device.This facilitates correct wind

speed measurement without eddies. The distance concurrently prevents spray (rain-

drops hitting the device) or snow (snow penetration) from impairing the measurement.

It also does not allow birds to bite it.

Fig. 1

There must be at least 60 cm of space below,

to the sides and in front of the sensor left

from other elements (structures, construction

parts, etc.).

Fig. 2

The wind sensor must be mounted on a verti-

cal wall (or a pole).

6 Installation and commissioning

Wind Sensor KNX W • Status: 11.11.2021 • Technical changes reserved. Errors reserved.

2.2. Mounting the sensor

2.2.1. 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. 3

The wind sensor must be mounted in the

horizontal transverse direction (horizontally).

2.2.2. View of rear side and drill hole plan

Fig. 6

Different mounting arms are available from Els-

ner Elektronik as additional, optional accessories

for flexible installation of the weather station on

a wall, pole or beam.

Example of the use of a mounting arm:

Due to flexible ball joints, the sensor can be

brought into ideal position.

2.2.3. 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 20...30

V DC version).
