1.Description
The Weather Station Suntracer KNX sl basic for the KNX building bus system
measures temperature, wind speed, brightness and recognises precipitation. All values can be used for the control of limit dependent switching outputs. States can be linked via AND logic gates and OR logic gates. Multi-function modules change input data
as required by means of calculations, querying a condition, or converting the data
point type.
The compact housing of the Suntracer KNX sl basic accommodates the sensors,
evaluation circuits and bus-coupling electronics.
Functions:
•Brightness measurement (current light strength) with 3 sensors. Separate
values, maximum or mixed value usable
•Wind measurement: The wind strength is measured electronically and thus
noiselessly and reliably, even during hail, snow and sub-zero temperatures.
Even turbulent air and rising winds in the vicinity of the device are recorded
•Precipitation detection: 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
•Frost protection for shading systems
•Switching outputs for all measured and computed values. Threshold values
can be adjusted per parameter or via communication objects
•8 AND and 8 OR logic gates, each with 4 inputs. 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 configured optionally
as 1-bit or 2 x 8-bit
•8 multi-function modules (computers) for changing the input data by
calculations, by querying a condition or by converting the data point type
Configuration is made using the KNX software ETS. The product file can be downloaded from the Elsner Elektronik homepage on www.elsner-elektronik.de in the “Service” menu.

2.Installation and start-up
2.1.Installation notes
Installation, testing, operational start-up and troubleshooting should
only be performed by an electrician.
CAUTION!
Live voltage!
There are unprotected live components inside the device.
•National legal regulations are to be followed.
•Ensure that all lines to be assembled are free of voltage and take
precautions against accidental switching on.
•Do not use the device if it is damaged.
•Take the device or system out of service and secure it against
unintentional use, if it can be assumed, that risk-free operation is no
longer guaranteed.
The device is only to be used for its intended purpose. Any improper modification or
failure to follow the operating instructions voids any and all warranty and guarantee
claims.
After unpacking the device, check it immediately for possible mechanical damage. If it
has been damaged in transport, inform the supplier immediately.
The device may only be used as a fixed-site installation; that means only when assembled 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.
2.2.Installation location
Select an installation position on the building where the sensors can measure wind,
rain and sunshine without hindrance. No structural elements should be mounted above the weather station, from which water could continue to drop on the precipitation
sensor even after it has stopped raining or snowing. The weather station should not be
shaded by structures or, for example, trees.
At least 60 cm of clearance must be left around the device. This facilitates correct wind
speed measurement without eddies. At the same time, this prevents spray (raindrops
hitting the device) or snow (snow penetration) from impairing the measurement. This
also prevents birds from biting it.
Please ensure that the extended awning does not cast shade on the unit, and that it is
protected from the wind.

Temperature measurements can also be distorted by external influences such as warming or cooling of the building structure on which the sensor is mounted (sunlight, heating or cold water pipes). Temperature variations from such sources of interference
must be corrected in the ETS in order to ensure the specified accuracy of the sensor
(temperature offset).

2.4.Installing the weather station
ATTENTION!
Even a few drops of water can damage the device electronics.
•Do not open the device if water (e.g. rain) can get into it.
2.4.1. Preparation for installation
2.4.2. Fitting the lower part with mounting

2Programming LED (under the semi-transparent lid)
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 the equipment
The equipment is delivered ex works with the bus address 15.15.250. You program a
different address in the ETS by overwriting the address 15.15.250 or teach the device
using the programming button.
The programming button can be reached through the opening on the underside of the
housing; it is recessed by approx. 15 mm. Use a thin object to reach the key, e. g. a
1.5 mm² wire.
4.Maintenance
WARNING!
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.

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.
