4 Equipment Description

The WS family is a range of low cost smart combination of weather sensors for the acquisition of a variety of measurement variables, as used for example for environmental data logging in road traffic management systems. Depending on the model, each device has a different combination of sensors for the various measurement variables.

*) WS401-UMB and WS601-UMB use a rain gauge for precipitation measurement **) is also valid for WS302-UMB, WS303-UMB, WS304-UMB, WS310-UMB ***) is also valid for WS502-UMB, WS503-UMB, WS504-UMB, WS510-UMB ****) leaf wetness measurement is no longer supported by devices with device version > 47

Sensors marked (ext) in the table are additional accessories and not included with the device. The table shows which external sensors can be connected to the different models.

Note: The external temperature sensor and the external rain gauge use the same input, so only one of them can be connected simultaneously.

Attention: Please note that, due to the approval of the radar sensor used, there are different country options on equipment which includes precipitation measurement by radar technology.

The equipment is connected by way of an 8 pole screw connector and associated connection cable (length 10m).

The measured values are requested over the RS485 interface in accordance with UMB protocol.

During commissioning, configuration and measurement polling takes place using the UMBConfig-Tool (Windows® PC software).

4.1 Air Temperature and Humidity

Temperature is measured by way of a highly accurate NTC-resistor while humidity is measured using a capacitive humidity sensor. In order to keep the effects of external influences (e.g. solar radiation) as low as possible, these sensors are located in a ventilated housing with radiation protection. In contrast to conventional non-ventilated sensors, this allows significantly more accurate measurement during high radiation conditions.

Additional variables such as dewpoint, absolute humidity and mixing ratio are calculated from air temperature and relative humidity, taking account of air pressure.

4.2 Air Pressure

Absolute air pressure is measured by way of a built-in sensor (MEMS). The relative air pressure referenced to sea level is calculated using the barometric formula with the aid of the local altitude, which is user-configurable on the equipment.

Operating Manual Smart Weather Sensor

4.3 Precipitation

Tried and tested radar technology from the R2S-UMB sensor is used to measure precipitation. The precipitation sensor works with a 24GHz Doppler radar, which measures the drop speed and calculates precipitation quantity and type by correlating drop size and speed. WS401-UMB and WS601-UMB are using an unheated rain gauge for precipitation measurement. This version can be recommended for low power application etc.

4.4 Wet Bulb Temperature

The wet bulb temperature is the temperature of a moist or icy surface exposed to air flow.

4.5 Specific Enthalpy

Parameter of state of the humid air, composed of the specific enthalpies (heat capacity) of the components of the mixture and related to the mass fraction of the dry air (at 0°C).

4.6 Air Density

The air density indicates how much mass in a given volume of air is contained and it is calculated from the measured values of air temperature, humidity and air pressure.

4.7 Wind

The wind meter uses 4 ultrasonic sensors which take cyclical measurements in all directions. The resulting wind speed and direction are calculated from the measured run-time sound differential. The sensor delivers a quality output signal indicating how many good readings were taken during the measurement interval.

4.8 Compass

The integrated electronic compass can be used to check the north – south adjustment of the sensor housing for wind direction measurement. It is also used to calculate the compass corrected wind direction.

4.9 Heating

The precipitation sensor and wind meter are heated for operation in winter.

4.10 Global Radiation

The global radiation is measured by a pyranometer mounted in the top cover of the Smart Weather Sensor.

4.11 Lightning Sensor

WS800-UMB includes lightning detection by an integrated sensor analysing the radio wave emission of lightnings. It delivers a count of recognized lightnings.

The sensor analyses spectrum and wave form of the received signal to suppress the detection of man made electrical discharges. Nevertheless false detections can not be totally excluded specially in an environment with high power electrical equipment.

4.12 Leaf Wetness

WS401-UMB and WS601-UMB can be equipped with an external sensor for leaf wetness evaluation.

Note: The external leaf wetness sensor is no longer supported by devices with device version > 47.

4.13 External Temperature Sensor

Optionally all models may be equipped with an external NTC temperature sensor for the acquisition from additional measurement points. The type of NTC is the same as used for the internal air temperature sensor.

External temperature sensor and external rain gauge can not be connected at the same time.

4.14 External Rain Gauge

Models without integrated precipitation acquisition can be equipped with an external rain gauge.

5 Generation of Measurements

5.1 Current Measurement (act)

In accordance with the specified sampling rate, the value of the last measurement is transmitted when the current measurement value is requested. Each measurement is stored in a circular buffer for the subsequent calculation of minimum, maximum and average values.

5.2 Minimum and Maximum Values (min and max)

When requesting the minimum and maximum values, the corresponding value is calculated via the circular buffer at the interval (1 – 10 minutes) specified in the configuration - and transmitted.

Note: In the case of wind direction, the minimum / maximum value indicates the direction at which the minimum / maximum wind speed was measured.

5.3 Average Value (avg)

When requesting the average value, this is calculated - via the circular buffer at the interval (1 – 10 minutes) specified in the configuration - and transmitted. In this way moving averages can also be calculated.

For some values the standard deviation is calculated for the same interval. The calculation of standard deviation will only be activated after the related UMB channel has been requested for the first time.

5.4 Vectorial Average Value (vct)

In the specific case of wind measurement, measurements are calculated vectorially. To this end, the average values of the vectors are generated internally. Hence the value (wind speed) and angle (wind direction) of the vector are calculated.

Note: On delivery, the interval for the calculation of minimum, maximum and average values is set at 10 minutes. If necessary, this can be adjusted to the particular requirements (1 – 10 minutes) with the aid of the UMB-Config-Tool (see page 30).

Note: The evaluation of the standard deviation values is deactivated after power on of the device. 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.

Note: The second measurements are averaged over 10 seconds for the output of the current (act) measurement. The 'fast' channels deliver every second a value.

The minimum / maximum wind direction indicates the direction at which the minimum / maximum wind speed was measured.

The corrected wind direction is calculated from the wind direction measured by the wind sensor and the heading measured by the compass.

Optionally the compass correction of the wind direction can be activated for all wind direction values. (Settings by UMB Config Tool)

Note: The correction function is designed for correction of the wind direction of a statically mounted sensor. If the alignment of the sensor changes during the measurement (i.e. if the sensor is mounted on a rotating platform or similar) the correction function will not in all cases work properly, especially not for the vector average.

It is of course possible to use the correction function for mobile measurement units, where the alignment is changed between measurement periods.

*) Note: The evaluation of the standard deviation values will be activated after the first request of a standard deviation channel. Please see p. 11.

6.10 Wind Measurement Quality

Sampling rate 10 seconds Unit % Request channels:

Note: The value is updated every 10 seconds and transmits the minimum wind measurement quality for the last 10 seconds interval.

The “fast” value indicates the measurement quality of the one second measurement value. This value allows the user to assess how well the measurement system is functioning in the

respective ambient conditions. In normal circumstances the value is 90 - 100%. Values up to 50% do not represent a general problem. If the value falls towards zero the measuring system is reaching its limits.

If during critical ambient conditions the system is no longer able to conduct reliable measurements, error value 55h (85d) is transmitted (device unable to execute valid measurement due to ambient conditions).

6.11 Compass

(only device version 030 or higher) Sampling rate: 5 min Unit ° Request channels:

Note: Reliable operation of the compass is only possible, if the sensor has been mounted according to the instructions in this manual, i.e. on top of the pole. Should the sensor be mounted on a traverse, the distribution of iron masses will be different from the situation during factory calibration. This may lead to additional deviation of the bearing. This also applies to lightning rods mounted at the pole top!

Dependent on the location of the installation the local declination of the earth magnetic field has to be considered. The declination value is entered using the UMB-Config-Tool (see page

32). The declination for the installation location can be found in the Internet, e.g. at

http://www-app3.gfz-potsdam.de/Declinationcalc/declinationcalc.html

http://www.ngdc.noaa.gov/geomagmodels/Declination.jsp

Note: When the fan is not rotating the compass measurement value will be influenced by the

magnetic field of the fan. Normally the compass measurement will be performed with the fan rotating to compensate this influence. If, starting from device version 037, the fan will not be switched on in case of low operating voltage (less than 12V) deviations of the compass measurement value must be accepted.

Note: When the device is operated in Power Saving Mode 1 or 2 the compass measurement is performed only once after power on. Later changes of the orientation of the device will not be recognized.

Note: The device versions with radar technology (WS400-UMB, WS600-UMB) calculate the precipitation intensity from the accumulated precipitation differences of the last 6 minutes before the measurement data request.

The lower resolution of the rain gauge would lead to high fluctuation of the intensity values, so the rain gauge versions (WS401-UMB and WS601-UMB), as well as the external rain gauge, use the accumulated precipitation of the last 60 minutes prior to the current measurement for intensity calculation.

7 Installation

The sensor bracket is designed to be installed on the top of a mast with a diameter of 60 – 76mm.

The following tools are required for the installation:

 Open-end or ring spanner (SW13)  Compass for aligning the wind meter to the North

7.1 Fastening

Figure 2: Fastening to the Mast

 Loosen nuts  Push the sensor onto the top of the mast from above  Tighten the nuts evenly until contact is made with the springs but the sensor can still be

moved easily

 Align the sensor to the North (for wind meters)  Tighten both nuts with 3 revolutions

Operating Manual Smart Weather Sensor

Point of reference in the North

Figure 3: North Markings

Figure 4: Alignment to North

7.2 North Alignment

In order for the wind direction to display correctly, the sensor must be aligned to the North. The sensor has a number of directional arrows for this purpose.

Procedure:

 If the sensor is already installed, first loosen both nuts evenly until you can turn the sensor

easily

 Using the compass, identify the North and fix a point of reference on the horizon  Position the sensor in such a way that the South and North wind sensors are in alignment

with the fixed point of reference in the North

 Tighten both nuts with 3 revolutions

poor good Note: As the magnetic North Pole indicated by the compass differs from the Geographic

North Pole, account must be taken of the declination (variation) at the location when aligning the sensor.

Depending on the location, the variation can be more than 15° (in North America for example). In Central Europe the variation can be largely ignored at present (< 3°). You can find further helpful information on this subject on the Internet.

Operating Manual Smart Weather Sensor

7.3 Selecting the Installation Location

In order to guarantee long service life and correct equipment operation, please pay attention to the following points when selecting the installation location.

7.3.1 General Instructions

 Stable subsurface for installing the mast  Free access to the equipment for maintenance works  Reliable power supply for permanent operation  Good network coverage when transmitting over a mobile communications network

Note: The computed measurements specifically apply to the equipment location only. No conclusions can be drawn with regard to the wider environment or a complete road section.

ATTENTION:

 Only approved and tested appliances (conductors, risers etc.) should be used to install the

device on the mast.

 All relevant regulations for working at this height must be observed.  The mast must be sized and anchored appropriately.  The mast must be earthed in accordance with regulations.  The corresponding safety regulations for working at road side and in the vicinity of the

road carriageway must be observed.

If the equipment is installed incorrectly

 It may not function.  It may be permanently damaged.  Danger of injury may exist if the equipment is allowed to fall.

7.3.2 Sensors with Wind Measurement / Compass

 Installation at the top of the mast  Installation height at least 2m above the ground  Free field around the sensor

Note: Buildings, bridges, embankments and trees may corrupt the wind measurement. Equally, passing traffic may cause gusts which may influence the wind measurement.

Note: for accurate compass readings, an aluminium mast is recommended.

7.3.3 Sensors with Radar Precipitation Measurement

 Installation on the top of the mast  Installation height at least 4.5m above the ground  Distance to road carriageway at least 10m  Distance from moving objects (e.g. trees, bushes and even bridges) at least 10m at the

height of the sensor

Note: Falling or moving objects, e.g. falling leaves or leaves blowing in the wind, may cause false measurements and/or precipitation types.

Note: Strong wind can influence the accuracy of the precipitation measurement. Note: When selecting the installation location please take care to position the device at a

suitable distance from other systems incorporating a 24GHz radar sensor, such as traffic counting devices on overhead gantry signs. Otherwise cross effects and system malfunctions may occur. In the final analysis, the distance to other measuring systems also depends on their range of coverage and signal strength.

The cable marking is in accordance with DIN 47100.

View on sensor connection

Note: The yellow protective cap must be removed before plugging in the equipment. If the equipment is not connected correctly

- It may not function

- It may be permanently damaged

- The possibility of an electrical shock may exist

The supply voltage and the heating voltage are protected against polarity reversal. Note: When operating the Smart Weather Sensor in SDI12 mode, line 3 (green) shall be

connected only if the SDI12 logger is DC-isolated from the supply voltage of the device. If signal ground (SDI-12-GND) of the data logger and power supply ground are identical, only the SDI12-Data-Line (line 4, yellow) may be connected.

Note for SDI12 operation of devices starting from device version 42 or 51 (WS700): If data logger and device supply voltage are DC-isolated the signal ground (SDI12_GND) must be connected to line 1 (white). Line 3 (green) shall not be connected. (see SDI12

connection drawings in chapter 19.6)

8.1 Supply Voltage

The supply voltage for the Smart Weather Sensor is 12 - 24V DC. The power supply unit used must be approved for operation with equipment of protection class III (SELV).

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).

26 G. Lufft Mess- und Regeltechnik GmbH, Fellbach, Germany

Operating Manual Smart Weather Sensor

8.1.1 Limitations in 12V mode

If the heating is operated on 12V DC, account must be taken of the functional restrictions in winter operation.

Note: A heating voltage of 24V DC is recommended to guarantee full heating duty.

8.1.2 Limitations in Case of Operation with Supply Voltage Below 12V

When operating a Smart Weather Sensor (device version >= 037) with supply voltages lower than 12V DC, the fan will be not switched on, independent of the fan operating mode. This may influence the accuracy of temperature and humidity measurement in case of solar radiation.

Additionally deviations of the compass measurement values have to be accepted. When operating the Smart Weather Sensor in Power Save Modes with supply voltages

below 12V the minimal supply voltage depends on the length of the connection cable. The minimal permitted supply voltage (U

)can be approximately evaluated from the

Bmin

equation: U

= 4V + 0.3V (cable length / m)

Bmin

The minimal supply voltage for a 10m cable is then U

= 6V. The influence of the cable

Bmin

length on minimal supply voltage can be reduced by using of a cable with larger wire cross section.

8.2 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.

8.4 Use of Surge Protection (8379.USP)

When using surge protection (Order No.: 8379.USP), please pay attention to the connection example in the surge protection operating instructions.

8.5 Connection of the Leaf Wetness Sensor

The sensor versions WS401-UMB and WS601-UMB (precipitation measurement by rain gauge) can be equipped with an optional external leaf wetness sensor.

The connection terminals for the leaf wetness sensor are located inside the rain gauge module. The sensor connection cable is put through the cable bushing in the wall of the rain gauge module and connected to the terminals (see Chap. 18.1).

8.6 Connection of External Temperature and Precipitation Sensors

External sensors are to be connected to pins 5 and 6 of the plug connector, i.e. to the gray and pink wires of the cable delivered with the Smart Weather Sensor.

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.

9 Commissioning

After the equipment has been installed and connected correctly, the sensor begins autonomously to take measurements. A Windows® PC with serial interface, UMB-ConfigTool software and interface cable (SUB-D 9 pole; jack - socket; 1:1) are required for configuration and test purposes.

Attention must be paid to the following points: Check for correct equipment operation on site by carrying out a measurement request with

the aid of the UMB-Config-Tool (see page 36).

 Configure the local altitude in order to ensure the correct calculation of relative air

pressure (see page 32).

 The device must be aligned to the North in order to ensure correct wind measurement

(see page 23), or the automatic compass correction must be activated (see page 32).

 In order to get correct compass headings the local declination must be configured (see

page 18and 32).

 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.

Operating Manual Smart Weather Sensor

10 Configuration and Test

Lufft provides Windows® PC software (UMB-Config-Tool) for configuration purposes. The sensor can also be tested and the firmware updated with the aid of this software.

10.1 Factory Settings

The Smart Weather Sensor is delivered with the following settings:

Class ID: 7 (cannot be modified) Device ID: 1 (gives address 7001h = 28673d) Baud rate: 19200 RS485 protocol: Binary Calculation interval: 10 measurements Local altitude: 0 m

Note: The device ID must be changed if several Smart Weather Sensors are operated on a UMB network, as each device requires a unique ID. It makes sense to start from ID 1 and continue in ascending order.

10.2 Configuration with the UMB-Config-Tool

The operation of the UMB-Config-Tool is described in detail in the operating instructions for the Windows® PC software. For this reason only the menus and functions specific to the Smart Weather Sensor are described here.

10.2.1 Sensor Selection

The Smart Weather Sensor is shown here with sensor selection WSx-UMB (Class ID 7).

Modbus-RTU, Modbus-ASCII, Terminal-Mode, XDR).

Timeout: In the event of a temporary changeover of the communications protocol, the

system switches back to the configured protocol after this time (in minutes)

Important note: If the baud rate is changed, after saving the configuration on the sensor, the sensor communicates at the new baud rate. When operating the sensor in a UMB network with ISOCON-UMB, this baud rate must not be changed; otherwise the sensor is

no longer addressable and can no longer be configured.

10.2.4 Temperature, Humidity and Fan Settings

Offset: Absolute offset on the measurement in the unit of the accompanying

channel (for on-site calibration).

Interval: Time in minutes for the minimum, maximum and average value calculation

interval.

Fan: to reduce electrical power consumption, the fan can be switched off.

Note: if the fan is switched off, all heaters will also be switched off! With the fan switched off deviations in temperature and humidity measurement can occur by solar radiation!

Note: In order to calculate dew point, absolute humidity and mixing ratio, the temperature

and humidity measurement always requires the same interval. For this reason different intervals cannot be set.

10.2.8 Precipitation Sensor Settings (Rain Gauge)

The rain gauge module can be operated with resolutions 0.2mm or 0.5mm. The setting of the resolution is to be done in two steps:

 Mechanical setting  Configuration setting

The mechanical setting works by modifying the effective area of the funnel. The sensor is delivered with a reduction ring, which can be mounted on the funnel to reduce the area.

Funnel with reduction ring resolution 0.5mm Funnel without reduction ring resolution 0.2mm Then the resolution is set in the sensor configuration using the UMB Config Tool.

Caution: If mechanical setting and configuration setting do not conform, the sensor will deliver wrong precipitation values!

10.4 Operating Modes of the Smart Weather Sensor

The power consumption of the Smart Weather Sensor can be adjusted to the properties of the individual installation by setting the operation mode.

The operation of the power save modes however has certain constraints. These have to be considered when designing the installation.

In normal operation, where all specified properties of the Smart Weather Sensor are fully available, the power consumption is mostly determined by heating and fan operation.

10.4.1 Power Saving Mode 1

Following measures are active in power saving mode 1:

 The ventilation of the temperature / humidity unit is switched off  All heaters are switched off  The radar rain sensor (WS700-UMB, WS600-UMB, WS400-UMB) is not working

continuously. The sensor is activated once per minute for one second, if precipitation is detected, it remains turned on until the end of the event, otherwise it is deactivated after this one second again.

 Compass measurement is only performed once after power up. The fan, which is

otherwise deactivated, will be switched on shortly for the time of this measurement.

 The WS700-UMB increases the measuring cycle time for global radiation from 10 seconds

to 1 minute. Note: This setting has the following restrictions:

 With the fan switched off deviations in temperature and humidity measurement can occur

by solar radiation.

 Only limited winter operation is possible in this operating mode because any icing might

prevent the correct operation of the rain sensor or wind meter.

 The rain detection may be delayed up to 2 minutes. Short events are possibly not

detected. Thus, deviations in the accuracy of the precipitation quantity are possible. 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).

Operating Manual Smart Weather Sensor

10.4.2 Power Saving Mode 2

Power saving mode 2 permits another relevant reduction of the power consumption, but adds on the other hand more severe restrictions.

In this operation mode the device will be almost completely switched off and will wake up only by the data request for one measurement cycle. During measurement and data transmission the device will be switched on for about 10 – 15 sec. The total consumption will be mostly determined by the data request interval.

Note: This operating mode has the following restrictions:

 All restrictions of power saving mode 1  Power saving mode 2 is not available for devices with radar rain sensor (WS700-UMB,

WS600-UMB, WS400-UMB). We recommend devices with tipping bucket rain gauge for low power applications.

 The calculation of average, minimum and maximum as well as precipitation intensity are

not available. Only instantaneous values will be transmitted.

 Compass measurement is only performed once after power up. The fan, which is

otherwise deactivated, will be switched on shortly for the time of this measurement.

 Communication protocol Modbus is not available  When using the UMB protocol a certain request sequence and timing is required (s. Chap.

19.3.7). The interval length must be at least 15sec to make sure that the measurement and transmission cycle can be completed. Shorter interval could cause the device to stay in transmission state without starting a new measurement.

 The joint operation with other sensors in an UMB network is possible, but it has to be

considered that each telegram (even when addressed to another device) will cause the Smart Weather Sensor to wake up for at least several seconds, thus increasing the total power consumption. The minimum interval length must be hold up under consideration of the telegrams with other addresses. Mixed operation of devices in power saving mode 2 with devices in normal operation and fast request rates within the same UMB network is not possible.

10.5 Operating Modes for Equipment Heating

Heating is configured to ‘Automatic’ when the product is delivered. This is the recommended operating mode for heating the sensor.

You can set the following operating modes:

*) is also valid for WS502-UMB, WS503-UMB, WS504-UMB, WS510-UMB **) is also valid for WS700-UMB

Note: Model WS30x-UMB and WS401-UMB are not heated. The rain sensor and wind meter settings must be adjusted in the respective configuration

mask. The examples show the wind meter setting.

10.5.1 Automatic

In this operating mode, the sensor is maintained constantly at the control temperature, generally in order to prevent the effects of snow and ice.

Setpoint Temp.: The heating controls at this temperature (in °C) The settings for the other values are not relevant.

10.5.2 Off

In the ‘Off’ operating mode heating is completely disabled. Winter operation is not possible in

this operating mode because any icing might prevent the correct operation of the rain sensor or wind meter.

The value settings are not relevant.

10.5.3 Mode 1

In ‘Mode 1’ operating mode heating is only enabled when the outside temperature falls below

the HeatingMode1 temperature (in °C). In this mode power consumption can be reduced in frost-free situations with no great restriction on winter operation.

Setpoint Temp.: The heating controls at this temperature (in °C) Heating mode1 Temp.: Threshold temperature (in °C) with effect from

which air temperature heating is enabled The ‘Eco Mode1 follow-up time’ setting is not relevant.

G. Lufft Mess- und Regeltechnik GmbH, Fellbach, Germany 39

Operating Manual Smart Weather Sensor

10.5.4 Eco-Mode 1

Eco Mode1 is an advanced energy saving mode. Heating is only switched on when the following conditions are met:

 The outside temperature is below the threshold temperature and precipitation was

detected. Heating then runs at the control temperature for 30 minutes (after the last precipitation event).

 When the outside temperature lies constantly below the threshold temperature and there

was no heating for more than 20h, heating is switched on for 30 minutes as a precautionary measure in order to thaw any icing.

However, the precautionary 20h-heating only runs if the outside temperature was measured at below the threshold temperature for the entire period and conditions were constantly bright for at least 3 hours.

Setpoint Temp.: The heating controls at this temperature (in °C) Heating mode1 Temp.: Threshold temperature (in °C) with effect from

which heating is enabled Eco mode1 follow-up time: Follow-up time (in minutes) Examples: Outside temperature constantly below 5°C; no precipitation for more than 24h

Outside temperature constantly below 5°C; with precipitation

11 Firmware Update

To keep the sensor in accordance with the latest state-of-the-art, it is possible to carry out a firmware update on site with no need to remove the sensor and return it to the manufacturer.

The firmware update is carried out with the aid of the UMB-Config-Tool. The description of the firmware update can be found in the instructions for the UMB-Config-

Tool. Please download the latest firmware and UMB-Config-Tool from our website

www.lufft.com and install it on a Windows® PC. You can find the instructions here:

Note: When a firmware update takes place, under certain circumstances the absolute precipitation quantities are reset (channel 600 – 660).

There is one firmware for the entire product family which supports all models (WSx_Release_Vxx.mot).

Important Note: please read the included text file in WSx_Release_Vxx.zip; it contains important information about the update!

12 Maintenance

In principle the equipment is maintenance-free.

However, it is recommended to carry out a functional test on an annual basis. When doing so, pay attention to the following points:

 Visual inspection of the equipment for soiling  Check the sensors by carrying out a measurement request  Check the operation of the fan (not on WS200-UMB)

In addition, an annual calibration check by the manufacturer is recommended for the humidity sensor (not on WS200-UMB). It is not possible to remove or replace the humidity sensor. The complete Smart Weather Sensor must be sent to the manufacturer for testing.

Cleaning of the glass dome at regular intervals is suggested for devices with global radiation measurement. The length of the interval should be adapted to the local degree of pollution.

Devices with precipitation measurement by rain gauge (WS401-UMB, WS601-UMB): The rain gauge funnel needs to be cleaned at regular intervals (see below). The length of the interval should be adapted to the local degree of pollution.

Devices with leaf wetness sensor: Cleaning of the leaf wetness sensor at regular intervals is suggested. The length of the interval should be adapted to the local degree of pollution. A check and, if necessary, adjustment of the “Wet” threshold is recommended to include into the maintenance procedure.

G. Lufft Mess- und Regeltechnik GmbH, Fellbach, Germany 41

Operating Manual Smart Weather Sensor

Figure 22: WS601-UMB with removed funnel

12.1 Maintenance of the Rain Gauge

The function of the rain gauge will be significantly influenced by pollution of the funnel or the tipping bucket mechanism. Regular check and, if necessary, cleaning is required. The maintenance interval depends very much on local conditions and also on seasons (leaves, pollen, etc.) and therefore cannot be exactly defined here (it may be in the range of weeks).

 Only clean when obviously polluted  Avoid moving the tipping mechanism (otherwise wrong counts will occur)  Use water, soft cloth and / or a soft brush for cleaning  Unlock funnel by turning it to the left and lift it off  Clean funnel, specially the sieve slots  Check the inside of the rain gauge module for pollution, especially for spider webs

and insects, if necessary, clean it

 Check tipping bucket for pollution, if necessary wash carefully with clean water.

Caution: each movement of the bucket generates a counting pulse and thus may cause faulty precipitation amounts

 Check water drain, clean if necessary  Put funnel back in place and lock it by turning it to the right

Error description

Cause - Remedy

Device does not allow polling / does not respond

- Check power supply

- Check interface connection

- Incorrect device ID  check ID; devices are

delivered with ID 1.

The device measures precipitation but it is not raining

Check that the sensor was installed correctly in accordance with the instructions.

The measured temperature appears too high / measured humidity appears too low

Check the operation of the fan on the underside of the device.

Wind direction values are incorrect

Device is not correctly aligned  check that the device is aligned to the North.

Device transmits error value 24h (36d)

A channel is being polled that is not available on this device type; e.g. Channel 200 = humidity is being polled on a WS200-UMB.

Device transmits error value 28h (40d)

The device is in the initialization phase following startup the device delivers measurements after approx. 10 seconds.

Device transmits error value 50h (80d)

The device is being operated above the limit of the specified measuring range.

Device transmits error value 51h (81d)

The device is being operated below the limit of the specified measuring range.

Device transmits error value 55h (85d) during wind measurement

The device is unable to execute a valid measurement due to the ambient conditions.

This may be due to the following reasons:

- The device is being operated well above the limit of the specified measuring range

- Very strong horizontal rain or snow

- The wind meter sensors are very dirty  clean

sensor

- The wind meter sensors are iced over  check heating mode in the configuration and check heating function / connection

- There are foreign objects within the measuring section of the wind meter

- One of the wind meter’s sensors is faulty  return device to manufacturer for repair

The quality of the wind measurement is not always100%

In normal operation the device should always transmit 90 – 100%. Values up to 50% do not represent a general problem.

When the error value 55h (85d) is transmitted this value is 0%.

If the device permanently transmits values below 50% this may mean that there is a fault.

Device transmits an error value not listed here

This may be due to a number of reasons  contact the manufacturer’s technical support department.

The leaf wetness sensor will, depending on the degree of wetness on the surface of the sensor leaf, output a voltage between ca. 500mV and 1200mV (UMB-Channel 710). The state wet / dry (UMB- Channel 711) is evaluated from this voltage using an adjustable threshold.

The threshold is pre-set to 580mV (factory setting). It should be checked after installation and, if necessary, adjusted.

Use the UMB Config Tool to measure channel 710 and collect values of the dry sensor for about 10min (see chapter 10.3 Function Test with UMB Config Tool).

The dry leaf value measured should be constant over the measurement interval. We recommend to set the threshold about 20mV higher than the dry leaf voltage:

Example: measured (dry leaf): 577mV threshold setting597mV The threshold value thus evaluated is set into the configuration using the UMB Config Tool.

Note: We recommend to check the threshold during maintenance and to adjust it if necessary. For the dry leaf measurement the sensor should be cleaned with clear water and carefully dried.

18.2 External Temperature and Precipitation Sensors

18.2.1 Connection of Temperature and Precipitation Sensors

Additional external sensor can cover the requirements of special measurement requirements or extend the functionality of Smart Weather Sensors.

Currently the accessory list includes external temperature sensors and the precipitation detection by tipping bucket rain gauge.

One input is available for this extension, so alternatively one temperature sensor or one precipitation sensor may be used.

The connection uses the standard connector plug of the Smart Weather Sensor, so normally the external device will be connected at the end of the cable included with the delivery, in the control cabinet. As this cable is part of the measuring line care shall be taken when designing the cabling to avoid parasitic coupling etc. The cable should be as short as possible. In special cases, e.g. when the external sensor is mounted near to the Smart Weather Sensor while the control cabinet is distant, the installation of an additional distribution box should be considered.

The external sensor is connected to pins 5 and 6 of the connector plug, i.e. the grey and pink wires of the standard cable.

All currently available sensors are unipolar, so the connection sequence is not relevant.

The Smart Weather Sensor must be configured for the selected type of external sensor (temperature or precipitation) to enable the correct evaluation of the measurement data. The selection of the sensor type is done through the UMB Config Tool.

If the data from the channels of the sensor type currently not selected are requested, the device will respond with “invalid channel”.

18.2.2 External Temperature Sensor

All models of the WS family can be used with an external temperature sensor. For different application various types of NTC sensor are in supply:

 WT1 for temperature acquisition of devices and surfaces  WST1 for mounting in the road surface (road surface temperature)

Mounting / installation of the temperature sensors is shown in the sensor manual.

18.2.3 External Rain Gauge

All models of the WS family without integrated precipitation detection can be used with an external rain gauge. Models WS400-UMB, WS600-UMB, WS401-UMB, WS601-UMB, WS700-UMB with R2S sensor resp. integrated tipping bucket cannot be equipped with an external rain gauge.

The measurement values of the external rain gauge are on the same channels as the data of the internal precipitation sensors of WS400-UMB, WS600-UMB, WS401-UMB, WS601-UMB and WS700-UMB.

The external rain gauge WTB100 uses the same technology as the integrated rain gauge of models WS401-UMB and WS601-UMB.

The resolution of the rain gauge WTB100 can be modified by the reduction ring delivered with the sensor from 0.2mm to 0.5mm.

In principle, all rain sensors with bounce-free reed contact (normally open or normally closed) and with a resolution of 0.1 mm, 0.2 mm, 0.5 mm or 1.0 mm can be used.

Note: To get the correct amount of rain this “mechanical” selection must be also be set in Smart Weather Sensors configuration.

The setting is done with the UMB Config Tool by the same procedure as with WS401-UMB and WS601-UMB (s. Chap.10.2.8).

The WS601/401-UMB’s advices for installation (Chap.7.3.4) and maintenance (Chap.12.1) are as well valid for the external rain gauge.

Example with WS501-UMB and WTB100 without reduction ring:

19.3 Communication in Binary Protocol

Only one example of an online data request is described in this operating manual. Please refer to the current version of the UMB Protocol for all commands and the exact mode of operation of the protocol (available for download at www.lufft.com).

Note: Communication with the sensor takes place in accordance with the master-slave principle, i.e. there may only be ONE requesting unit on a network.

19.3.1 Framing

The data frame is constructed as follows:

SOH Control character for the start of a frame (01h); 1 byte <ver> Header version number, e.g.: V 1.0 <ver> = 10h = 16d; 1 byte <to> Receiver address; 2 bytes <from> Sender address; 2 bytes <len> Number of data bytes between STX and ETX; 1 byte STX Control character for the start of payload transmission (02h); 1 byte <cmd> Command; 1 byte <verc> Version number of the command; 1 byte <payload> Data bytes; 0 – 210 bytes ETX Control character for the end of payload transmission (03h); 1 byte <cs> Check sum, 16 bit CRC; 2 bytes EOT Control character for the end of the frame (04h); 1 byte Control characters: SOH (01h), STX (02h), ETX (03h), EOT (04h).

19.3.2 Addressing with Class and Device ID

Addressing takes place by way of a 16 bit address. This breaks down into a Class ID and a Device ID.

ID = 0 is provided as broadcast for classes and devices. Thus it is possible to transmit a broadcast on a specific class. However this only makes sense if there is only one device of this class on the bus; or in the case of a command, e.g. reset.

19.3.3 Examples for Creating Addresses

If, for example, you want to address WS400-UMB with the device ID 001, this takes place as follows:

The class ID for the Smart Weather Sensor is 7d = 7h; the device ID is e.g. 001d = 001h

Putting the class and device IDs together gives the address 7001h (28673d).

19.3.4 Example of a Binary Protocol Request

If, for example, a Smart Weather Sensor with the device ID 001 is to be polled from a PC for the current temperature, this takes place as follows:

Sensor:

The class ID for the Smart Weather Sensors 7 = 7h; The device ID is 001 = 001h Putting the class and device IDs together gives a target address of 7001h.

PC:

The class ID for the PC (master unit) is 15 = Fh; the PC ID is e.g. 001d = 01h.

Putting the class and device IDs together gives a sender address of F001h. The length <len> for the online data request command is 4d = 04h; The command for the online data request is 23h; The version number of the command is 1.0 = 10h. The channel number is in <payload>; as can be seen from the channel list (page 66), the

current temperature in °C in the channel is 100d = 0064h. The calculated CRC is D961h.

The request to the device:

The response from the device:

Interpretation of the response:

<status> = 00h device o.k. (≠ 00h signifies error code; see page 71) <typ> = Data type of the following value; 16h = float (4 bytes, IEEE format) <value> = 41B40000h as a float value corresponds to 22.5 The temperature is therefore 22.5°C.

The correct data transmission can be checked with the aid of the check sum (22C6h). Note: Little Endian (Intel, low byte first) applies when transmitting word and float variables of

addresses or the CRC, for example. This means first the LowByte and then the HighByte.

If a measurement request delivers the <status> 00h, the sensor is working correctly. You can find a complete list of additional codes in the description of the UMB protocol.

Extract from list:

19.3.6 CRC Calculation

CRC is calculated according to the following rules: Norm: CRC-CCITT Polynomial: 1021h = x16 + x12 + x5 + 1 (LSB first mode) Start value: FFFFh You can find further information in the description of a CRC calculation in UMB Protocol.

19.3.7 Data Request in Power Saving Mode 2

When in power saving mode2 the processor of the Smart Weather Sensor will be usually in sleep state. For the acquisition of measurement data a certain command sequence and a certain timing is required:

 „Wake Up“ bei sending a <Break>, any character or any telegram (a telegram will

not be properly detected and get no response, because the UART is just starting)

 1000msec pause for the processor start up  Activation of the measurement cycle by (any) valid telegram addressed to this

device

 2000msec pause for the execution of the measurement sequence  Request of the measurement results

19.4 Communication in ASCII Protocol

Text-based communication with devices is possible using ASCII protocol. To do this, in the device configuration, interface settings, the protocol mode must be set to

ASCII (see page 31). ASCII protocol is network-compatible and serves exclusively for online data requests. The

device will not respond to incomprehensible ASCII commands. Note: The use of binary protocol is recommended for lengthy transmission routes (e.g.

network, GPRS/UMTS), as ASCII protocol is unable to detect transmission errors (not CRCsecured).

Note: TLS channels are not available in ASCII protocol.

19.4.1 Structure

An ASCII command is introduced by the ‘&’ character and completed by the CR (0Dh) sign.

There is a space character (20h) between the individual blocks in each case; this is

represented by an underscore character ‘_’. Characters that represent an ASCII value are in

ordinary inverted commas.

19.4.2 Summary of ASCII Commands

These operating instructions describe the online data request only. You can find the description of the other commands in the UMB protocol.

19.4.3 Online Data Request (M) Description: By way of this command, a measurement value is requested from a specific

channel.

Request: ‘&’_<ID> Response: ‘$’_<ID>

_‘M’_<channel>

_<value>5 CR

<ID>5 Device address (5 decimal places with leading zeros) <channel>5 Indicates the channel number (5 decimal places with leading zeros) <value>5 Measurement value (5 decimal places with leading zeros); a measurement

value standardized to 0 – 65520d. Various error codes are defined from

65521d – 65535d. Example: Request: &_28673_M_00100 By way of this request, channel 100 of the device with address 28673 is interrogated (Smart

Weather Sensor with device ID 001). Response: $_28673_M_00100_34785 This channel outputs a temperature from –50 to +60°C, which is calculated as follows:

0d corresponds to -50°C 65520d corresponds to +60°C 36789d corresponds to [+60°C – (-50°C)] / 65520 * 34785 +(-50°C) = 8.4°C

Note: TLS channels are not available in ASCII protocol.

19.5 Communication in Terminal Mode

It is possible to communicate with a device in a very simple text-based manner using the terminal mode.

To do this, in the device configuration, interface settings, the protocol mode must be set to terminal (see page 31).

Note: In the case of communication in the terminal mode, only one single unit may be connected to the interface, as this protocol is NOT network-compatible. It is used for very simple measurement value requests.

Note: The use of binary protocol is recommended for lengthy transmission routes (e.g. network, GPRS/UMTS), as it is not possible to detect transmission errors in terminal mode (not CRC-secured).

Note: In the terminal mode, measurement values are not available in all units. Furthermore, status and error messages are not transmitted.

19.5.1 Structure

A terminal consists of an ASCII character and a numeric character. The command is completed with the <CR> sign. There is no echo on entry.

The individual values in the response are separated by a semi-colon (;). The response is completed with <CR><LF>.

An invalid terminal command is acknowledged with ‘FAILED’. Control commands are

acknowledged with ‘OK’.

The command to which the response relates is given at the beginning of each response. Note: No response times are specified in the terminal mode.

19.6 Communication in SDI-12 Mode

The communication in the SDI-12 mode of the Smart Weather Sensor is conforming to the

standard defined in ‚SDI-12 A Serial-Digital Interface Standard for Microprocessor-Based Sensors Version 1.3 January 12, 2009‘ . The device may be operated in bus mode together

with other SDI-12 sensors, connected to one SDI master (logger).

19.6.1 Preconditions for SDI-12 Operation

As the interface settings defined in the SDI-12 standard are significantly different from the UMB default settings the related parameters have to be set properly by the UMB Config Tool (latest version!).

The protocol mode of the device has to be set to “SDI-12”. This will automatically set the baud rate to 1200.

Measurement data can be transmitted alternatively in metric or US units. The selection is done by the UMB Config Tool.

Metric units US units

Note: Please observe drawings on next page and notes on page 26 when connecting a SDI12 data logger!

Operating Instructions Smart Weather Sensor

Figure. 41: Connecting to a logger with integrated power supply

When operating the device in SDI-12 mode it is basically no more possible to access the device with the UMB Config Tool, due to the different interface parameter settings. To enable configuration access nevertheless the interface is operated in standard UMB mode (19200 8N1) for the first 5 seconds(*) after reset / power on. During this time the UMB device ID, if unequal 1, is set to 200, so access will be possible even if the device ID is unknown. If a valid UMB telegram is received within this 5 sec, the device will stay in UMB mode for the configured time out (several minutes) so that the configuration can be modified.

 Connect the PC to the Smart Weather Sensor through an RS-485 converter  Start the UMB Config Tool and create a WSxxx-UMB with the address (1 or 200) of

the actual device and activate at least one sensor. Start the measurement (will report connection error at first)

 Reset the device (Power off / on)  When measurement values are received the measurement can be terminated, the

interface is now open for configuration.

(*) Remark: The 5 seconds UMB communication are available from program start. Under consideration of the operating system start, where no communication is possible, the device will be ready for SDI12 requests after 7.0 – 7.5 seconds.

This timing only applies in case of cold start after power on or reset. This phase will not

occur after “wake up” in Power Saving Mode 2. In this case the device will respond within the

time defined by the SDI12 standard.

The composition of the minimal and the full basic data set depends on the variant (WS200UMB ... WS700-UMB) of the device in question (see below). The same applies to the availability of the additional measurement commands (aM1!, aC1! etc.)

Due the applied measurement processes the devices of the WS family will, different from other sensors described in the SDI-12 document, in normal operation mode always measure continuously. This causes some special properties while in this mode:

 The device does not need a “Wakeup” and does not have a sleep mode. So the

reactions to “Break” signals and any related timings are inapplicable. “Break” will be

ignored by WS devices.

 Data requested with M- or C- commands are always available immediately. The

device will always respond with a000n resp. a000nn. This means the device will not send any service request and will ignore measurement abort signals. The logger should request the data immediately.

 M- and C- command only differ in the number of values made available in the buffers

(in both cases the maximum permitted by the standards of 9 resp. 20).

 We recommend to use the commands for continuous measurement (R-commands)

to request the data.

 When in power saving mode 2 the device will wake up by a „Break“ signal. Other

functions of the „Break“ signal are not implemented.

 When in power saving mode 2 the device responds to M or C commands with

a002n resp. a002nn and holds the data available within 2 seconds. It will not send a service request, signals to abort the measurement are ignored.

 For the reduced data set in power saving mode 2 a unified data buffer structure for

all device models has been defined. Depending on the individual model unused channels will be set to the “invalid” marker 999.9.

19.6.3 Address Configuration

UMB Device-ID and SDI-12 Address are connected, but the different address ranges and the fact, that UMB ID’s are integer numbers, while SDI-12 addresses are ASCII characters, have to be considered.

The SDI-12 address is built from the UMB device ID as follows: UMB Device ID 1 (default) corresponds to SDI-12 Address ‘0’ (SDI-12 default). Changing the SDI12 address by SDI12 setting command also modifies the UMB device ID

accordingly.

Valid Address Ranges:

19.6.4 Data Messages

In the interest of simplified evaluation the assignment of measurement values to data buffers ‘0’ ... ‘9’ has been defined unified for all measurement commands. For this reason the responses to C-requests have been restricted to 35 characters, not using the 75 characters permitted for these requests

Currently buffers ‘0’ to ‘4’ are in use. As with M-requests max. 9 values may be transmitted; the base data set of 9 values has

been assigned to buffers ‘0’ and ‘1’. Buffers ‘2’ to ‘4’ contain further measurement values.

This definition guaranties the compatibility to loggers designed according to older versions of the SDI-12 standard.

The buffer assignment depends on the device variant (WS200-UMB ... WS700-UMB). The complete set of measurement values, as defined for the UMB protocol has been made

available also in the SDI-12 environment. They can be accessed using the additional M and C commands (aM1! ... aM8!, aMC1! ... aMC8!, aC1! ... aC8!, aCC1! ... aCC8!) (see below).

If the measurement value is not available for some reason, e.g. sensor failure, this is indicated by a value of +999.0. or -999.9 The logger can then evaluate the reason of failure by a aV! Verification request. The following tables show the measurement values in the sequence they are arranged in the telegram (see example).

Depending on the configuration of the device the values will be transmitted in metric or US units.

Note: The configured system of units is not indicated in the data messages. The logger may request this setting with the I-command and adjust the evaluation of the data messages accordingly
