Suntracer KNX basic
Weather Station
Technical specifications and installation instructions
1. Description
The Weather Station Suntracer KNX basic perceives temperature, wind
speed, brightness and precipitation. All data may be used for the control of swit-
ching outputs which depend on threshold values. The states may be linked by me-
ans 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
•Wind sensor monitoring: If the wind measurement value changes by less
than ± 0.5 m/s within 48 hours, a fault can be output. The wind measured
value is output with the maximum measured value of 35 m/s and all wind
threshold values below this value become active
•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 dow-
nloaded from the Elsner Elektronik website on www.elsner-elektronik.de in the
“Service” menu.
1.1. Scope of delivery
• Weather station with combined wall/pole mounting
• 2x stainless steel installation band for pole installation
1.2. Technical specifications
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
devices 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
unintentional switch-on if risk-free operation is no longer guaranteed.
Use the device exclusively for building automation and observe the operating ins-
tructions. Improper use, modifications to the device or failure to observe the ope-
rating instructions 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 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.
2.0.1. Location
Select an assembly location at the building where wind, rain and sun may be col-
lected by the sensors unobstructedly. Do not assemble any construction compo-
nents 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 facilita-
tes correct wind speed measurement without eddies. The distance concurrently
prevents spray (raindrops hitting the device) or snow (snow penetration) from im-
pairing 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 in-
terference must be corrected in the ETS in order to ensure the specified accuracy
of the sensor (temperature offset).
2.1. Mounting the weather station
2.1.1. 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

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

2.1.3. Weather station layout
2.1.4. 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 20...32 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 and bus +/- to the provided
clamps.
For 20...32 V DC devices the connection cable must be plugged in between the co-
ver and circuit board.

20...32 V DC version
2.1.6. 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”.
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.
2.2. 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
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.
The measured wind value and thus all other wind switching outputs may only be
supplied 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.
3. Addressing of the device at the bus
The device is supplied with the bus address 15.15.255. You can program another
address into the ETS by overwriting the 15.15.255 address or by teaching via the
programming 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.
5. Disposal
After use, the device must be disposed of or recycled in accordance with the legal
regulations. Do not dispose of it with the household waste!
