1. RQCommancder Installation RQCommander software is easy to install First insert Installation CD Sommer CD and start the Setup exe program out of the CD_ RQCommander_V2 0 X X folder The dialogue process will guide you through the installation The easiest and the recommended way is to select standard installation and the default installation path C DME RQCommander Note Due to restricted admission rights it is important not to choose the Program files folder for installation path Note If you want to update your RQCommander installation please use always repair option 5 Connecting RQ 30 and PC What has to be done step by step 1 Open up the 4 side bottom screws of the RQ 30 and lift its cover to plug in the Sommer main cable at the RQ 30 Make sure that your connection is good by listening and feeling of the engaging noise and feel of the bayonet nut connector 2 Connect USB Nano 485 converter to the Sommer main cable by using the small clamps on the converter and the small slot screw driver o The yellow wire RS 485 A wire must be connected to the A clamp o The grey wire RS 485 B wire must be connected to the B clamp Note If the RS 485 bus system have another devices planned for e g a data logger separate them from the bus wiring while parametrisation Otherwise this could lead to many crash situations by double mastering of the bus system 3 Prepare power supply to be connected with RQ 32. maximum discharge of the river or channel In advance you can estimate the minimal and maximal water level of the site This guide is meant for averaged PC users and all guide parts are written in a common explanation form with intent because some windows dialogues can differ from windows to windows version 2 Required Equipment To check out the delivered RQ 30 equipment in the office you will need some additional things This is guide is written for a delivered Sommer main cable If you build the cable by your own see RQ 30 user manual chapter 2 4 check the wiring by your own specifications Total equipment list o RQ 30 delivered o Sommer main cable delivered o 9 24 Volt power source with capability of at least 200 mA current o Maybe some wirings an clips to do the power connection o USB nano 485 converter and an USB extension cable delivered o A PC or Notebook with a free USB port and a Windows operating system Win XP or later with administration rights and a CD ROM drive o A installation CD of RQCommander and in the case of no internet connection the installing CD of the USB nano 485 converter delivered o A small screwdriver to connect the USB nano 485 converter to the Sommer main cable o A medium Phillips screwdriver to open up the body housing of the RQ 30 to plug in the Sommer main cable 3 USB nano 485 Installation USB nano 485 converter installation consists of two separately drivers First driver to
3. confirm its safety retrieval You will see a new connection window with a progress bar and a lot of communication in the terminal window When this process is finished the RQ 30 is ready for first parametrisation If you don t have updated your RQ 30 version you don t have to do this procedure once again cause the RQCommander software now know all RQ 30s parameter names and ranges and stores this information in a schema locally 10 We recommend to close the RQCommander software now because then the next chapter shows as a first example what you normally doing with the RQCommander software 6 Setup RQ 30 6 1 Get actual Parameters from RQ 30 First you have to open a new RQ Commander session by starting the RQCommander exe file The most important thing for now to do is to connect with RQ 30 to get its actual parametrisation 1 Check your wiring and the power supply see chapter 5 2 Select parameters tab Check the right COM number see chapter 3 and its baudrate in the connection window see chapter 5 3 Push button Load Parameter on the left side of the screen to let the RQCommander fill the local stored Schema with the actual parameters of the RQ 30 Wait until the whole process is finished Note The RQ 30 is normal measurement mode while loading parameter This could lead to some data crash situations on RS 485 because the RQ 30 pushes out the measurement data from time to time The loading process of RQ
4. you can compare the values in the RQ 30 with them in the RQ 30 List on the profile tab screen Note It is not necessary to use the same units in the profile settings as they are on the RQ 30 RQCommander automatically adapting the meaning of the values 6 4 RQ 30a Analog Output Setup Only if you are using a RQ 30a with 4 20 mA analog outputs IOUT this part of setup the RQ 30 concerns to you All analogue output settings should be checked by the user because their settings are also strongly combined with the measuring site The usage of them is always technical stuff and it is not just part of the RQ 30 also the 4 20 mA input system has to be adjusted in a compatible way Here is a step by step guideline for set up the IOUTs correctly 1 2 Click on the sign before Technics if it is not already opened then click on sign before 4 20mA outputs Now all possible 4 20 mA output parameters are drop down Then choose your site dependant settings Note It is not too important to select the ranges and offsets absolutely closely to site In most cases it is better to do it in a balanced way especially if you have more than one RQ 30 and want to have the same settings for all sites In this case it is best to check out the settings with the biggest site o IOUT1 AUX In most cases IOUT1 settings are not relevant cause the input is has been turned off Otherwise the setting is strongly dependant of what you are measuring P
5. 0 o The brown wire wire must be connected to the side of the power supply o The white wire wire must be connected to the side of the power supply ATTENTION Make sure that there are no possibilities for electrical shortcuts in the power supply wiring Switch off the power supply and start RQ commander software Select the Parameter Tab and click in the connection so it becomes a blue frame 6 Choose at the Com Port field your COM X number of the USB Nano 485 converter see Chapter 3 Point 5 6 Select baudrate 9600 because it is the RQ 30s default baudrate The check marks in the connection field must be cleared 7 Click on terminal window so it becomes a blue frame and then click on the most left button which means connect The terminal should go online and shows the COM number and the baudrate in the terminal frame headline When an error message does occur check if you have the correct COM number X see chapter 3 of this guide 8 Switch on RQ 30s power supply and wait 5 seconds Now the boot message of the RQ 30 should appear at the black terminal window If it doesn t something is wrong with the RQ 30 or its wiring Also the settings in connection frame could be wrong Please check voltage and the correct polarisation of the power supply 9 Have a look at the left screen side There is a button Load Schema For the first usage of a new RQ 30 system you have to Load Schema first Feel free to push it and
6. 30 is doing its own recovery in these situations so don t care about some strange looking characters in the terminal window or some red written lines in the progress bar window 6 2 Units and Decimals lf all parameters are loaded the RQ Commander shows in the middle of the screen in the window Sensor parameters the filled out actual parameters of the RQ 30 You can have a look at the actual parameters set but please before you do any customizing set your own designed set of units and decimals This is very helpful because many parameters are dependant of these settings You can avoid a lot of work of reparametrisation if you choose your units first To do this 1 Click on the sign before Technics then the Technics sub menu is drop down Then click on sign before Units and decimals and you will see the actual default unit and decimal settings of the RQ 30 Select your combination of your preferred units and select well balanced decimals Dependant of your measuring site the decimals should not to be set to big cause the maximum amount of decimal digits of a output value are 7 For example A site with a maximal discharge of 9999 cubic ft per second should not have more than 3 decimals for the discharge otherwise the value could not be transferred in especially high water situations Note Most times the AUX measurement is not in use than the setting of its units is not important Per default the AUX is set for a IR t

12. ies implemented which should be set soon as possible To make sure your RQ 30 is delivering the information you will need we recommend to do the first settings in the office This guide leads you through the PC installation of delivered RQ 30 parametrising tools and the most important customer settings It is helpful to get familiar with the technics and needed information before mounting the RQ 30 system on the site O O The designed measurement site is suitable see RQ 30 user manual chapter 4 1 To get a valid discharge from the RQ 30 you have to fill out its discharge table RQCommander can build this table automatically but you have to put in the cross section profile of the river or channel Before you can setup the RQ 30 completely you must get the profile data of your measuring site see RQ 30 user manual chapter 3 3 and chapter 5 1 You have think about your level gage measuring coordinate system called W Character W represents the chosen Water level coordinate system and where your cross section profile is placed in this system Also the mounting height of the RQ 30 have to be placed in this coordinate system by doing a level adjustment or doing a direct setting of RQ 30 level WRQ parameter see RQ 30 user manual chapter 5 2 You have to choose your output units so the data collecting system e g a data logger can be set up as well Some of these settings are site size dependant so you should have an idea of
13. install is the USB nano 485 USB Controller and the second one is the USB Serial port driver A detailed explanation what to do follows afterwards USB nano 485 converter is shortly called converter 1 Put in the converter in one USB slot of your PC In most cases Windows detects a new USB device and starts the driver installation which is called USB nano 485 automatically If windows doesn t please make sure you have administration rights and then have a look at Start gt Control Panel gt System and Security gt System gt Device Manager and look there under Other Devices for USB nano 485 and start the driver installation from there 2 If you have an opened internet connection let windows search there for the most actual driver when you will be asked for by the installation dialogue This works fine in some cases but if windows can t find a matching driver start the installation dialogue once again until the point where it asks you Browse my computer for driver software and click on this option now Please insert the Installing CD for the converter CTI CD and give in the CD ROM path In most cases the root directory path of the CD ROM is deep enough and windows find the correct driver in the subdirectories by its own check mark option 3 At the next step in the dialogue Windows will tell you that the driver has no valid digital signature You have to accept this circumstance before you can install t
14. olute unpredictable way The internal inclination measurement of the RQ 30 and its influence on the interpretation of the measured Doppler frequencies makes it also difficult to get a correct distribution of moved test objects If you like you could change screen tab of the RQCommander to spectrum and push the spectral mode button to check out the RQ 30 sensibility for measuring moved objects but concern that the spectral distributions of these objects are mostly not typical for a river so RQ 30 software sometimes evaluate these spectral distributions as failure measurements Also level measurements sometimes work in the office but you have to wait at least 60 seconds after turn up the radar and you have to use are a good radar reflector as a metal plate in at least 1 m distance and perpendicular to the RQ 30 But if the test doesn t work it is not definitely the failure of the RQ 30 it could be also a failure of the test setup 8 Helpful Support Information To give you an optimal support in case of troubles we need possibly a lot of information of the site 1 At the end of all RQCommander sessions when parametrising the RQ 30 load the actual parameter set of the RQ 30 see chapter 6 1 and push Save Parameter File button to save it If you will use our support we can do it much faster when we can load this parameter file here at company to have an overview what is going on there 2 If you have completed your
15. profile in the RQCommander see chapter 6 3 in this guide or chapter 5 1 in the RQ 30 user manual please store your work To do this make sure your actual screen is the profile tab screen and then go right up to the file menu of the RQCommander There should be a menu point which is called Save Profile or press CTRL S Click it and so you can work further later if open the file once again It is important to know that the profile data have much more information than just the discharge table of the RQ 30 For example just the profile data file contains the whole geometry of the river bed For our support this information is also important too so please if you have any profile data please send us this file as well 3 Make some pictures of a site especially from river itself and the position of the RQ 30 It is also good to make a picture the rivers surface on the measuring spot If the RQ 30 shows sometimes strange data most times it gives us and you a lot of interesting information when you go to the site and make the pictures right then when RQ 30 is not working well And if you will be there throw a small piece of wood in the river and try to estimate the velocity of the rivers surface 4 lf you have any external information about the site and its specialities please tell us Helpful for us could be some answers of these questions o Are there another river mouths nearby the measuring site o Does the RQ 30 looking river upwa
16. rd or downward o Are there river power stations nearby o Is there a lake or the sea nearby o Are there any standing waves in the water This picture is just to have an idea what standing waves are and how big they can be o What are you think about the wave surface on the river do mean it is more or less than 3 mm 1 8 of an inch o Are there any moving objects nearby especially in the extension region of the water reflected radar spot Trees bushes grass wobbling in the wind railways streets o Is there any kind of a regularly ship movement on the river o If the measuring site is very windy is there a main wind direction or does direction change very often o Could there be any visible or sensible vibrations on the RQ 30 housing caused by traffic wind or something else o Is the RQ 30 mounted under the bridge or under a special roof Are there any possibilities of water down spouts in the radar cone area between radar spot and radar itself If you have the possibility to log all measured data so do this please For the supporting team especially the measured level velocity and quality are very helpful So if you have troubles and you have some timelines of these values please send us them as well
