3 Description
Weather Station Suntracer KNX basic • Version: 25.06.2018 • Technical changes and errors excepted.
1. Description
The Weather Station Suntracer KNX basic perceives temperature, wind speed,
brightness and precipitation. 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 Suntracer KNX basic stores the sensor system,
the evaluation electronics and the electronics of the bus connection.
Functions:
•Brightness measurement: The current light intensity is measured by means
of a sensor
•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
•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.

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 within the device.
• VDE regulations and national 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.

5 Installation and commissioning
Weather Station Suntracer KNX basic • Version: 25.06.2018 • Technical changes and errors excepted.
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.
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.
2.1.1. 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.
At least 60 cm of clearance must be left all round the weather station. This facilitates
correct wind speed measurement without eddies. The distance concurrently prevents
spray (raindrops hitting the device) or snow (snow penetration) from impairing the
measurement. It also does not allow birds to bite it. Please ensure that the extended
awning does not cast shade on the unit, and that this is not protected from the wind.
Temperature measurements can also be affected by external influences such as by
warming or cooling of the building structure on which the sensor is mounted, (sun-
light, heating or cold water pipes). Temperature variations from such sources of inter-
ference must be corrected in the ETS in order to ensure the specified accuracy of the
sensor (temperature offset).
Fig. 1
There must be at least 60 cm of space below,
to the sides and in front of the weather station
left from other elements (structures, con-
struction parts, etc.).

2.2. Mounting the weather station
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.

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 (pictures of sensors exem-
plary).
Example of the use of a mounting arm: Due to
flexible ball joints, the sensor can be brought
into ideal position.

2.2.3. Weather station layout
2.2.4. Connection of the weather station
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
cover (soldered cable connection in case of 230 V AC version, cable with plug in case
of 12...40 V DC, 12...28 V AC version).
Push the power supply and bus connection cable through the rubber seal on the bot-
tom of the weather station and connect voltage and bus +/- to the provided clamps.

12 Installation and commissioning
Weather Station Suntracer KNX basic • Version: 25.06.2018 • Technical changes and errors excepted.
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.
2.3. Notes on mounting and commissioning
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 sta-
tion 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 con-
necting the weather station.
Remove all existing protection labels after installation.
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 or sent via the
bus.
Fig. 16
With the 230V model, screw the cover on to
the underpart, to prevent unauthorised or ac-
cidental opening.
Fig. 17
Push the housing from above into the fas-
tened mount. The bumps on the mount must
snap into the rails in the housing.

13 Addressing of the device at the bus
Weather Station Suntracer KNX basic • Version: 25.06.2018 • Technical changes and errors excepted.
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.
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!
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 water penetrates the housing.
• Do not clean with high pressure cleaners or steam jets.
