1. Description
The Weather Station Suntracer KNX-GPS light light measures temperature,
wind speed and brightness. It perceives precipitation and receives the GPS signal
for time and position. Furthermore, the exact position of the sun (azimuth and ele-
vation) is calculated on the basis of location coordinates and time.
ATTENTION
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 thres-
hold values. The states may be linked by means of AND and OR logic gates. The
compact housing of Suntracer KNX-GPS light stores the sensor system, the
evaluation electronics and the electronics of the bus connection.
Functions:
• Brightness and position of the sun: The current light intensity is
measured by means of a sensor. At the same time, Suntracer KNX-GPS light
calculates the position of the sun (azimuth and elevation) on the basis of
time and location
• Shade control (Position of the sun in sector) for up to 5 facades
• 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
• Week and calendar time switch: The weather station receives time and
date from the integrated GPS 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
• Threshold values for all measured and calculated 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 product file can be dow-
nloaded from the Elsner Elektronik website on www.elsner-elektronik.de in the
"Service" menu.

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.
2.1. Installation position
Choose an installation position in the building where wind, rain and sun can be
measured unhindered by the sensors. The weather station must not be installed
underneath 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.
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.
The mounting position must be selected so that the sensors for rain and wind can-
not be touched by persons.
Please take note that an extended awning does not shade the device from sun and
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).
Magnetic fields, transmitters and interfering fields from electricity consumers (e.g.
fluorescent lamps, neon signs, switched-mode power supplies etc.) can interfere
with or even cut out reception of the GPS signal.

Different mounting arms are available
from Elsner Elektronik as additional, op-
tional accessories for flexible installation
of the weather station on a wall, pole or
beam.
Example of the use of a mounting arm:
Due to flexible ball joints, the sensor can
be brought into ideal position.
