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

nloaded from the Elsner Elektronik website on

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
the wall or pole.

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 (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.
