    2 Instrument schematic sun[e]’s scientific name is pyranometer. A pyranometer measures the solar radiation received by a plane surface from a 180 ° field of view angle. This quantity, expressed in W/m , is called “hemispherical” solar radiation. The solar radiation spectrum extends roughly from 285 to 3000 x 10 m.

    "most significant byte" is sent first. For values that go beyond one register (e.g. 32 bit) this is not clearly specified for the Modbus. In these cases (32 bit or 64 bit) the LAMBRECHT Modbus sensors follow the big-endian number format. Example Big-Endian: Register size value 16 - Bits 0x1234 is transmitted in the order: 0x12 0x34.

    Network communication: getting started Once it has the correct Modbus address and communication settings, sun[e] can be connected directly to an RS-485 network and a power supply. Installing a sun[e] in the network also requires configuring the communication for this new Modbus device.

  • Page 21: Maintenance And Trouble Shooting

    6 Maintenance and trouble shooting 6.1 Recommended maintenance and quality assurance sun[e] can measure reliably at a low level of maintenance in most locations. Usually unreliable measurements will be detected as unreasonably large or small measured values. As a general rule this means that regular visual inspection combined with a critical review of the measured data, preferably checking against other measurements, is the preferred way to obtain a reliable measurement.

  • Page 22: Trouble Shooting

    6.2 Trouble shooting Table 6.2.1 Trouble shooting for sun[e] General Inspect the instrument for any damage. Inspect if the connector is properly attached. Check the condition of the connectors (on chassis as well as the cable). Inspect if the sensor receives DC voltage power in the range of 8 to 30 VDC. Inspect the connection of the shield (typically not connected at the network side).

    = 8 Since the addresses from the range 30001 to 35000 apply to all Lambrecht sensors, an address from this range is also representative of a measured value type. For example, register 30401 always contains the current value of the air temperature. If this register address is not included in the list in register range 46001 to 49000, the connected Modbus sensor does not supply an air temperature.
