The function will be activated with the first request to any of the standard deviation channels. To get standard deviation values of the first integration period after power on a dummy request to any one of the standard deviation channels should be inserted. G. Lufft Mess- und Regeltechnik GmbH, Fellbach, Germany...
Note: For the correct calculation of relative air pressure, the altitude of the sensor must be entered in the device configuration (see Figure 11 on page 32). The factory setting for altitude is 0m; in this way both measurement variables deliver the same values. G. Lufft Mess- und Regeltechnik GmbH, Fellbach, Germany...

Starting with device version 037 the Smart Weather Sensor has an extended supply voltage range of 4 … 32V DC. Operation with a supply voltage of 24V is recommended. Limitations apply in case of supply voltages lower than 12V (see below). G. Lufft Mess- und Regeltechnik GmbH, Fellbach, Germany...
RS485 Interface The equipment has an electrically isolated, half-duplex, 2 wire RS485 interface for configuration, measurement polling and the firmware update. See page 43 for technical details. G. Lufft Mess- und Regeltechnik GmbH, Fellbach, Germany...
The temperature sensors as well as the external rain gauge are unipolar, so any connection sequence can be chosen. The type of external sensor has to be set using the UMB Config Tool. For details please refer to Chapter18. G. Lufft Mess- und Regeltechnik GmbH, Fellbach, Germany...
If several Smart Weather Sensors are operated on a UMB network, a unique device ID must be assigned to each device (see page 31). There is no protective cover to remove on the sensor itself. G. Lufft Mess- und Regeltechnik GmbH, Fellbach, Germany...
Note: You do require the current version of the UMB-Config-Tool to configure the Smart Weather Sensor. Note: All other devices which are used in the polling process, e.g. modems, LCOM etc., must be disconnected from the UMB network during configuration. G. Lufft Mess- und Regeltechnik GmbH, Fellbach, Germany...

Compared with normal operation the power consumption of a WS600-UMB can be reduced to 10% even neglecting the heating. (during precipitation events the consumption is slightly higher, due to the rain sensor then permanently switched on, about 20% compared to normal operation). G.
