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
•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
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 home-
page on www.elsner-elektronik.de in the “Service” menu.

2. Installation and commissioning
2.1. Notes on installation
Warning, mains voltage!
National legal regulations are to be observed.
Installation, inspection, commissioning and troubleshooting of
the device must only be carried out by a competent electrician.
Disconnect all lines to be assembled, and take safety precautions against accidental
switch-on.
The device 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 device 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 device 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 in-
tended for this purpose.
Elsner Elektronik does not assume any liability for changes in standards after publica-
tion of this instruction manual.
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 stop-
ped 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 or-
der to enable a correct wind measurement and in order to avoid that the weather sta-
tion is snowed in if there is heavy snowfall. 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).

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.

The wind sensor must be mounted onto a
vertical wall (or pole).

2.2.3. Preparing 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 24 V DC version).
Push the power supply and bus connection cable through the rubber seal on the bot-
tom of the weather station and connect voltage LN and bus +/- to the provided clamps.
For 24V devices the connection cable must be plugged in between the cover and circuit
board.

2.2.5. 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”.
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 da-
mage the electronic system.
Observe the correct connections. Incorrect connections may destroy the weather stati-
on 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 5 seconds. During this phase no information can be received via the bus.

Make sure the cover and bottom part are pro-
perly snapped together! This picture is loo-
king at the closed sensor from underneath.

Push the housing from above into the faste-
ned mount. The bumps on the mount must

12 Maintenance
Weather Station Suntracer KNX basic • Date of issue: 29.06.2012 • Technical changes reserved. Errors reserved.
3. Maintenance
The sensor 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.
As a precaution, the device should always be separated from
power supply for maintenance works (e.g. deactivate or remove
fuse).

If the threshold is set by parameters:
If the threshold is set by communication objects, a threshold which is valid
until the first communication of a new threshold must be determined for the
initial operation:
The thresholds set at last by communication objects are saved in EEPROM in order to
maintain them in case of voltage breakdown and to provide them as soon as there is
voltage supply again.
In case of an already commissioned weather station, the threshold which has
been communicated at last may be used:
As soon as a threshold has been set by means of a parameter or by means of a com-
munication object, the threshold set at last remains until a new threshold has been
transmitted by a communication object.
