3 Mode of Operation of the Laser Precipition Monitor A laser-optical beaming source (laser diode and optics) produces a parallel light-beam (infrared, 785 nm, not visible). A photo diode with a lens is situated on the receiver side in order to measure the optical intensity by transforming it into an electrical signal.
Diameter [mm] Fall speed [m/s] 0.2 (drizzle) 0.73 0.3 (drizzle) 0.8 (rain) 0.9 (rain) 1.8 (rain) 2.2 (rain) 3.2 (rain) 5.8 (rain) Table 1: Example for the speed of liquid particles The calculated data are memorized over one minute, and then transmitted via the serial interface. The instrument is almost maintenance-free.
Figure 3 :Schematic Block Diagram In explanation of the construction, and the basic function the block diagram Figure 3) shows schematically the most important functional connections (variant “Extended Heating” not shown). 4 Construction of the Measuring Instrument The Laser Precipitation Monitor consists of the following: a varnished aluminium housing, protection IP 65, a laser head ( anodised aluminium), fixed at the housing cover, a receiver head (anodised aluminium) fastened by means of carrier arms (see also Figure 4 and Figure 5) The aluminium housing contains the electronics with all necessary interfaces.
Attention: Do not look into the invisible laser beam! In case the laser caution labels on the housing are not legible any more the sensor must not be operated! Even with a longer exposure time the intensity of the invisible laser beam is considered as safe for the human eye (without using optical instruments).

4.1 Heating All sensor variants have heated glass panes on both heads to prevent interferences through freeze up, steaming up or similar. The heating power is controlled in subject to the ambient conditions. The heating current are measured for self diagnostic and could be read through the diagnostics command (“DD”, only available with PCB Rev.B, see Figure 6).
5 Installation Attention: The instrument must be mounted and wired only by a qualified expert, who knows and observes the generalities of technics, and applicable regulations and norms. Attention: Do not look into the invisible laser beam! In case the laser caution labels on the housing are not legible any more the sensor must not be operated! Even with a longer exposure time the intensity of the invisible laser beam is considered as safe for the human eye (without using optical...
should be mount with a distance of at least 1m on the same mast. The side distance to other objects should be greater than 2m. We recommend to operate the Laser Precipitation Monitor in an enclosed area for human safety, although the intensity of the invisible laser beam is considered as safe for the human eye (without using optical instruments, Laser Class 1M according to EN 60825-1:1994 A2:2001).

5.2.2 Mounting Angle First, the mounting angle (with or without housing) should be fastened at the mast. Because of the shading effect of the mast the angle is to be mounted at the highest possible place. Align the angle to the south acc. to Figure 10 (± 10°, Northern hemisphere), and fasten it at the top of the mast. It is advisable to have a second person holding the Laser Precipitation Monitor during the mounting.
5.2.3 Mounting of the Housing Cover Remove, first, the 4 screws in the edges. Afterwards, turn down the cover carefully. When the housing is open, please take care that no humidity (precipitation) can lay down on the electronics. 5.3 Electrical Installation Attention: The instrument must be mounted and wired only by a qualified expert, who knows and observes the generalities of technics,...
5.3.1 Electrical installation with cable glands In order to carry out an EMC-compatible installation the cable screen/shielding (except the supply cable, which, in general, is not shielded) is to be connected to the contact spring of the screwed cable gland (Figure 11). 1.
The cables are guided through the respective cable gland to the sensor connecting terminals (Figure 6 or Figure 7), see also wiring diagram (CH. 9). They are connected by means of the respective tension clamp technique. For the orange-coloured connecting terminals put a commercially available screw-driver with a blade width of up to 2mm resp.
5.3.1.1 Electrical Installation via Connector Instruments equipped with connectors, have pre-assembled flange plugs, which are integrated at the housing. The flange plug for the supply with pre-assembled cable has a ferrite sleeve which is already affixed at the cable (between plug and pc-board) against the wall by cable connector. 5.3.2 Closing the Instrument Cover Lift up the housing cover carefully, and take care that no cable is jammed between cover and housing.
6 Maintenance Attention: Do not look into the invisible laser beam! Attention: Head and carrier heatings could be hazardous hot! Burn Hazard! (applies only for 5.4110.x1.xxx) 6.1 Cleaning Approximately every 3 months the glass panes of the sensor should preventively be cleaned. Depending on the location this period might be different.
6.3.1 Checking the LED’s In case no terminal program with PC is available the checking of the Laser Precipitation Monitor is limited to the control of the following LEDs. You will see them after removing the cover (see Figure 6 or Figure 7): •...
6.3.2 Checking by means of a terminal program First, the Laser Precipitation Monitor must be connected to the respective COM interface of the used PC by an interface converter (RS485/RS232). Start a terminal program, and configure the interface according to the sensor interface (baud rate, parity, etc.).
7 Serial communication An RS485 interface (4-wire or 2-wire mode, changed by command “BD”, see CH. 7.2.1) with several baudrates (command “BR”) is available at the Laser Precipitation Monitor for the serial communication. The communication can be carried out, for example, by means of a standard terminal program and a PC.
7.1 General telegram format A fixed telegram format is used for the serial communication (<CR> means Carriage Return (enter key)): • Data request: „<id>BB<CR>“ <CR> means carriage return (enter key) • Change of parameters: „<id>BBppppp<CR>“ <CR> means carriage return (enter key) The single letters have the following meaning: Device address number (00…99, initial value 00) two-digit command code (case-insensitive)

Measuring quality: This value indicates the significance of the precipitation classification (parameter 11,12 and 13). The sensor analyse for this value the quantity of the particles and the measured ambient temperature. It should be considered that other factors (e.g. wind speed, dense fog) can decrease the measuring quality provided by the instrument.
Additional hints: • The code tables for SYNOP and METAR are described in the 506-sided WMO document number 306 (WMO-No.306 “Manual on Codes” Vol. I.1, 2010 edition) • The coding is done according the WMO guidelines in the precipitation type and the intensity step (see the both following tables Table 8 and Tabelle 9 Example: Sensor detects drizzle with 0.22mm/h intensity.
