Weather Station Suntracer KNX sl basic
• Status: 26.08.2021 • Errors excepted. Subject to technical changes.
•
Wind sensor monitoring
: If the wind measurement value changes by less
than ± 0.5 m/s within 48 hours, the maximum measurement value of 35 m/s is
output as a fault message. All wind alarms with a limit value below 35 m/s
become active as a result
•
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

Installation and start-up
3.1. 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 precipita-
tion 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. The
wind sensor must not come into contact with water. The distance also prevents birds
from biting the sensor.
The mounting position must be selected so that the sensors for rain and wind cannot
be touched by persons.
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).
