Product description

The Weather Station
brightness. It perceives precipitation and receives the DCF77 signal for date and time.
Furthermore, the exact position of the sun (azimuth and elevation) is calculated on the
basis of location coordinates and time.

The calculation of the position of the sun is optimised for
UTC -1...+3. The device therefore may only be applied within
Europe. For other time zones, please use Suntracer KNX-GPS
Weather Station.

All data may be used for the control of switching outputs which depend on threshold
values. The states may be linked by means of AND and OR logic gates.
The compact housing of
electronics and the electronics of the bus connection.

Functions and Operation:

• Brightness and position of the sun: The current light intensity is measured by

means of a sensor. At the same time, Suntracer KNX calculates the position of the
sun (azimuth and elevation) on the basis of time and location. The necessary
position coordinates (degree of longitude and latitude) are entered into the ETS
software

• Wind measurement: The measurement of wind speed is accomplished

electronically and thus noiseless and reliable even in case of hail, snow and minus
temperature. Air swirls and up-draught in the radius of the weather station are
collected, too

• Precipitation perception: The surface of the sensor is heated so that only drops

and flakes are recognised as precipitation but not fog or dew. If it stops raining or
snowing, the sensor dries quickly and the precipitation message ends

• Temperature measurement

• Week and calendar time switch: The weather station receives time and date

from the integrated DCF77 receiver. The week time switch operates up to 4
different periods each day. With the calendar time switch, you may determine 3
additional periods where the time switch accomplishes up to 2 activations and
deactivations each day. The Switching outputs can be used as communication
objects. The switching times are set by parameter or via communication objects

• Switching outputs for all measured and calculated 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

measures temperature, wind speed and

stores the sensor system, the evaluation

Configuration is accomplished by means of the KNX software ETS. The programme
file for KNX software ETS (format VD2) is ready for download on the Elsner Elektronik
website under www.elsner-elektronik.de in the “Service” menu.

Installation and commissioning

Attention! Mains voltage! The legal national regulations
must be complied with.

Installation, inspection, commissioning and troubleshooting of the weather station must
only be carried out by a competent electrician. Disconnect all lines to be assembled, and
take safety precautions against accidental switch-on.

The weather station is exclusively intended for appropriate use. With each inappropriate
change or non-observance of the instructions for use, any warranty or guarantee claim
will be void.

After unpacking the device, check immediately for any mechanical damages. In case of
transport damage, this must immediately notified to the supplier.

If damaged, the weather station must not be put into
operation.

If an operation without risk may supposedly not be guaranteed, the device must be put
out of operation and be secured against accidental operation.

The weather station must only be operated as stationary system, i.e. only in a fitted
state and after completion of all installation and start-up works, and only in the
environment intended for this purpose.

Elsner Elektronik does not assume any liability for changes in standards after
publication of this instruction manual.

Location

Select an assembly location at the building where wind, rain and sun may be collected
by the sensors unobstructedly. Do not assemble any construction components above
the weather station from where water may drop on to the rain sensor after it has
stopped raining or snowing. The weather station may not be shaded by the building or
for example by trees. Leave at least 60 cm of free space beneath the weather station in
order to enable a correct wind measurement and in order to avoid that the weather
station is snowed in if there is heavy snowfall.

Iron constructions or huge metal sheets directly behind or in the vicinity of the weather
station reduce the reception quality of the assembled radio clock receiver. Please take
this into consideration when selecting the assembly location. The reception of the DCF
signal may also be disturbed or made impossible by magnetic fields, emitters and

7

interfering fields of electrical consumers (e.g. fluorescent tubes, illuminated advertising,
switching power supply units, etc.).

Fig. 3: The weather station must be mounted
onto a vertical wall (or pole).

Fig.4: The weather station must be mounted
horizontally in the lateral direction.

Attaching the mount

The weather station 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. 5: When wall mounting: flat side on wall,
crescent-shaped collar upward.

Fig. 6: When pole mounting: curved side on pole,
collar downward.

Fig. 7: An additional, optional accessory
available from Elsner Elektronik is an articulated
arm for flexible wall, pole or beam mounting of
the weather station.

Examples for the application of the hinge arm mounting:

Ex.1: With the hinge arm mounting, the weather
station projects from beneath the roof. Sun, wind
and precipitation can be measured unhindered by
the sensors.

Ex. 2: Pole-mounting with mounting brackets.

Preparing the weather station

Fig. 9

The weather station cover with the rain sensor snaps in on the left and right along the
bottom edge (see Fig.). Remove the weather station cover. Proceed carefully, so as not
to pull off the wire connecting the PCB in the bottom part with the rain sensor in the

10

cover (soldered cable connection in case of 230 V AC version, cable with plug in case of
24 V DC version).

Push the power supply and bus connection cable through the rubber seal on the bottom
of the weather station and connect voltage LN and bus +/- to the provided clamps.

Aligning the DCF77 antenna

The antenna for DCF77 reception of date and time is located under the PCB in the
housing. Using the set screw (see chapter “PCB layout”, No. 8), you can turn the
antenna by up to 180° in order to achieve the best alignment. You know you are getting
reception when the control LED (No. 9) flashes regularly once every second (in second
59, the flashing interrupts once) The flashing may be displayed in the ETS programme
file (also see chapter “Setting of parameters: general settings“).

Mounting the weather station

Close the housing by putting the cover back over the bottom part. The cover must snap
in on the left and right with a definite “click”.

Fig. 10: Make sure the cover and bottom part are
properly snapped together! This picture is
looking at the closed weather station from
underneath.

Fig. 11: Push the housing from above into the
fastened mount. The bumps on the mount must
snap into the rails in the housing.

To remove it, the weather station can be simply pulled upwards out of the mount,
against the resistance of the fastening.

Details for the installation

Do not open weather station if water (rain) might ingress: even some
drops might damage the electronic system.
Observe the correct connections. Incorrect connections may destroy the weather station
or connected electronic devices.

Please take care not to damage the temperature sensor (small blank at the bottom part
of the housing.) when mounting the weather station. Please also take care not to break
away or bend the cable connection between the blank and the rain sensor when
connecting the weather station.

Remove all existing protection labels after installation.

The measured wind value and thus all other wind switching outputs may only be
supplied 60 seconds after the supply voltage has been connected.

Maintenance

The weather station must regularly be checked for dirt twice a year and cleaned if
necessary. In case of severe dirt, the wind sensor may not work properly anymore, there
might be a permanent rain message or the station may not identify the sun anymore.

As a precaution, the weather station should always be
separated from power supply for maintenance works (e.g.
deactivate or remove fuse).

Light in Lux
Wind in meters per second

The DCF signal may be slightly disturbed. It is possible that there is no radio clock
reception for a longer period of time. Therefore only use the indicated time for
synchronisation purposes of a clock which is operated parallel in your system. For this
purpose it is advisable to use second 0.
