These instructions for use describe all application and adjustment options for the device. These detailed instructions allow users to modify the factory settings to their needs via the serial interface of the Weather Station Compact FS6003. Scope of supply 1 Weather Station Compact FS6003.
COMPACT FS6003 (command interpreter: 18...28V AC MODBUS RTU) 2 Application The WEATHER STATION COMPACT FS6003 is designed for use in building services automation systems (e.g. shade protection control). The FS6003 features the following measured variables: • Wind speed. • Wind direction.
3 Structure / Mode of operation Wind speed / wind direction: Wind measurement is based on the hot wire principle. The underside of the housing is equipped with a heated cylindrical sensor. A PID controller adjusts the temperature of the cylinder to a temperature that is constantly increased in relation to the environment.

Air temperature: A PT1000 measuring resistor is used to measure the air temperature. The sensor is mounted on a flexible printed board and positioned in the lower section of the housing. Air pressure: Absolute air pressure is measured with a piezoresistive MEMS sensor. To make a meaningful comparison between air pressure values simultaneously measured at different locations, they need to be converted to a common datum (height above sea level).
The working position of the COMPACT FS6003 Weather Station is horizontal (plug connection underneath). During installation, de-installation, transport or maintenance of the COMPACT FS6003 Weather Station make sure that no water gets into the device and connector. 4.1 Selection of installation site An exposed position should be selected for this site.
4.2 Mechanical installation The intended installation of the Weather Station FS6003 requires the use of a pipe socket / pipe with an outside diameter of ≤25mm. The inside diameter must be ≥19mm to admit the connector and cable. Tool: Hexagon socket wrench SW2mm (socket wrench).
4.2.1 Alignment to north For the exact determination of wind- and brightness direction the WEATHER STATION COMPACT FS6003 must be mounted in north alignment (geographic north). The hexagon socket screw serves as north marking (N) Tool: Hexagon socket wrench SW 2mm (socket wrench).
4.3 Electrical installation The COMPACT FS6003 Weather Station is equipped with a 7-pin plug for electrical connection. A cable socket (mating connector) is included in the scope of supply. 4.3.1 Cable, cable preparation, connector installation The cable to be used for connection should have the following properties: 5 cores, core cross-section max.
