Suntracer KNX-GPS
Weather Station

2 Description
Weather Station Suntracer KNX-GPS • Date of issue: 30.03.2011 • Errors excepted. Subject to technical changes.
1. Description
The Weather Station Suntracer KNX-GPS measures temperature, wind speed and
brightness. It recognises precipitation and receives the GPS signal for time and loca-
tion. In addition, using location coordinates and the time, it calculates the exact positi-
on of the sun (azimuth and elevation).
All values can be used for the control of threshold value-dependent switching outputs.
States can be linked via AND logic gates and OR logic gates. The compact housing of
the Suntracer KNX-GPS accommodates the sensors, evaluation circuits and bus-
coupling electronics.
Functions:
•Brightness and position of the sun: The current light intensity is measured
by a sensor. In addition the Suntracer KNX-GPS calculates the position of the
sun (azimuth and elevation) using time and location
•Shade control for up to 6 facades with slat and shadow edge tracking
•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
•Precipitation recognition: The sensor surface is heated, so that only drops
and flakes are recognised as precipitation, but not mist or dew. When the rain
or snow stops, the sensor is soon dry again and the precipitation warning ends
•Temperature measurement
•Weekly and calendar time switch: The weather station receives the time
and date from the integrated GPS receiver. The weekly time switch switches up
to 4 different periods per day. With the calendar time switch up to 3 additional
time periods can be defined, in which up to 2 On/Off switches take place. The
switching outputs can be used as communications objects. The switch times
are set via parameters.
•Switching outputs for all measured and calculated values (threshold values
can be set via parameters or communications objects)
•8 AND and 8 OR logic gates with 4 for each input. All switching events as
well as 16 logic inputs (in the form of communications objects) can be used as
inputs for the logic gates. The output of each gate can be optionally configured
as 1-bit or 2 x 8-bit
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
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. Installation position
Choose an installation position in the building where wind, rain and sun can be mea-
sured unhindered by the sensors. The weather station must not be installed under-
neath any structural parts from which water can still drip onto the rain sensor after it
has stopped raining or snowing. The weather station must not be shaded by anything,
such as building structures or trees. There must be at least 60 cm of free space under-
neath the weather station to allow it to measure the wind correctly and to prevent it
from being snowed in when it snows. Please take note that an extended awning does
not shade the device from sun and wind.

5 Installation and commissioning
Weather Station Suntracer KNX-GPS • Date of issue: 30.03.2011 • Errors excepted. Subject to technical changes.
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).
Magnetic fields, transmitters and interfering fields from electricity consumers (e.g. flu-
orescent lamps, neon signs, switched-mode power supplies etc.) can interfere with or
even cut out reception of the GPS signal.
2.1.2. Mounting the weather station
2.1.3. Attaching the mount
The weather station comes with a combination wall/pole mount. The mount comes ad-
hered by adhesive strips to the rear side of the housing.
Fasten the holder vertically to the wall or pole.

2.1.5. Preparing the weather station
The weather station lid with the rain sensor latches into place on the lower edge to the
right and left (see figure). Remove the lid from the weather station. Proceed carefully
to avoid tearing off the cable connection between the circuit board in the lower section
and the rain sensor in the lid (cable with plug).
Lead the cable for the voltage supply and bus connection through the rubber seals on
the bottom of the weather station and connect Voltage L/N and Bus +/- to the terminals
provided.

10 Maintenance
Weather Station Suntracer KNX-GPS • Date of issue: 30.03.2011 • Errors excepted. Subject to technical changes.
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 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.
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.

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

11 Maintenance
Weather Station Suntracer KNX-GPS • Date of issue: 30.03.2011 • Errors excepted. Subject to technical changes.
As a precaution, the device should always be separated from
power supply for maintenance works (e.g. deactivate or remove
fuse).
