2 Weather Unit (WZ/S 1.1), Weather Sensor (WES/A 2.1) Overview Weather Unit WZS/1.1 MDRC Application program Sensor Data 2.0 Conversion not possible Weather Sensor WES/A 2.1 SM 9 Measured variables detectably 100 x 96 x 128 (H x W x D) Enclosure IP 44 2CDC N0204 Seite 2

3 Weather Unit (WZ/S 1.1), Weather Sensor (WES/A 2.1) Wiring diagram The designations are alike with both devices. 2CDC N0204 Seite 3

4 Weather Unit (WZ/S 1.1), Weather Sensor (WES/A 2.1) Technical Data Over the RS485-interface the data are conveyed to the Weather Unit. The devices are protected from exchanging the connections (1, 2, A or B). Communication Weather Unit and Weather Sensor: Cable connection Cable length Cable type 4 wires max. 100 m PYCYM (2x2x0.8mm) J-Y(ST)Y (2x2x0.8mm) 2CDC N0204 Seite 4

6 Weather Unit (WZ/S 1.1) Hardware Auxiliary voltage and data interface for Weather Sensor supply 1 (0V potential) 2 (24 V potential) A (RS485 interface) B (RS485 interface) Programming-button/LED Bus connection terminal Power supply 2CDC N0204 Seite 6

7 Weather Unit (WZ/S 1.1) Application program Sensor Data 2.0 Adjustable which Weathers Sensor are connected. Measured value represented in the appropriate type of data point, e.g. in m/s, in lux or in C. 2 threshold value each input with upper and lower limit / threshold value modified via the bus. Logic AND / OR, 4 inputs, invertible. 4 memory with 24 values / storage each takes place in the FiFo principle (ring puffer). Minimum duration underflow and over range adjustable (If the send communication reverts during the minimum duration, no telegrams are sent). Offset temperature +/- 5 C. 2CDC N0204 Seite 7

10 Functionality of the individual sensors Twilight Total measuring range Resolution Accuracy Lux 1 Lux +/- 200 Lux 2CDC N0204 Seite 10

11 Functionality of the individual sensors 3 x Brightness Right Left Middle Total measuring range 0, Lux Resolution Lux Measuring range Lux Accuracy +/ Lux Measuring range Lux Accuracy +/ Lux 2CDC N0204 Seite 11

12 Functionality of the individual sensors Rain The sensor surface is permanently heated. After a rain alarm, the rain message will continue to be issued for approximately another 6 minutes. The sensor surface is heated to approximately + 50 C above the ambient temperature. ATTENTION: Rain sensor is hot in the operation! 2CDC N0204 Seite 12

13 Functionality of the individual sensors Temperature Total measuring range - 25 C + 85 C Resolution 0,1 C Measuring range - 25 C + 10 C Accuracy +/- 2,5 K Measuring range + 10,1 C + 85 C Accuracy +/- 1,5 K 2CDC N0204 Seite 13

14 Functionality of the individual sensors Day / night Day => night Night => day > 10 Lux night < 10 Lux* * One minute and 15 seconds after the brightness value has exceeded 10 lux 2CDC N0204 Seite 14

15 Functionality of the individual sensors Wind Total measuring range Resolution Accuracy ( ) Accuracy (180 ) 0 24 m/s 0,1 m/s +/- 22 % from measure value +/- 15 % from measure value 2CDC N0204 Seite 15

16 Functionality of the individual sensors GPS Radio receiver of basis from GPS. Connection to a satellite is sufficient, in order to date and time. World-wide applicable. 2CDC N0204 Seite 16

17 Preparation of the Weather Sensors Cover with rain sensor Catches of the cover (left and right) Base The cover of the Weather Sensor is locked on the right and left side of the lower edge. Remove the cover from the Weather Sensor by pulling the catches carefully outwards. Be careful in order not to tear off the cable connection between the circuit board in the base and the rain sensor in the cover. 2CDC N0204 Seite 17

18 Installation of the holder Bridge Bridge The weather sensor includes a combined wall/pole holder. When the unit supplied, the holder is fastened to the back of the housing with adhesive tape. 2CDC N0204 Seite 18

19 Installation of the Weather Sensors Horizontal wall or pole The Weather Sensor is fastened horizontal and laterally with an assembly angle of 90. 2CDC N0204 Seite 19
