Product description 1 Product description 1.1 Function Continuous level measurement with ultrasonic sensors is based on the running time measurement of ultrasonic pulses. Since the speed of sound is subject to temperature influence, the transducer also continuously detects the ambient temperature, so that the level is precisely measured even in case of varying ambient temperature.
Product description 1.2 Application features 1.3 Profibus output signal Applications • Level measurement of all liquids. • Level measurement of solids (only short meas. distances) such as e.g. coal, ore, rocks, rock dust, cement, gravel, crushed rock, sand, sugar, salt, cereals, flour, granules, powder, dust, sawdust, wood chips. • Flow measurement on various flumes.
Product description Master-Class 1 is the actual automation system, i.e. the process control computer or the PLC enquires and processes all measured values. Master-Class 2 One or several Master-Class 2 can operate in a Profibus network. As a rule, Master-Class 2 devices are engineering, adjustment or visualisation stations.
Product description We are aware of the disadvantages of the HART® environment: for each sensor/participant an individual DD must be loaded which, in addition, must always be the latest and most up-to-date DD. Special adjustment options such as e.g., the output of an echo curve, are available neither with HART® nor with PDM. The SIMATIC-PDM adjustment concept was tailored more to the basic adjustment functions.
Product description The VEGA adjustment program VVO can access the entire spectrum of adjustment options of VEGA sensors and, if necessary, can update the complete sensor software. To do this, the adjustment program must be installed on a PC which is equipped with a Profibus-Master-Class 2 interface card (Softing) (see diagram on following page). The PC with the Profibus interface card can be connected directly at any point on the DP bus with the standard RS 485 Profibus cable.

Product description Adjustment with adjustment module MINICOM Adjustment with the SIMATIC PDM adjustment program With the small (3.2 cm x 6.7 cm) 6-key adjustment module with display in the sensor, the sensor-relevant adjustments can be carried out directly on the sensor. To adjust all essential functions of the VEGA sensor with the adjustment station SIMATIC PDM from Siemens, a so-called EDD is required. Without this EDD, only the basic functions, such as min./max.

Mounting and installation 4 Mounting and installation 4.1 General installation instructions Measuring range Beside other criteria, you select your instrument according to the required measuring range. The reference planes for the min. and max. distance to the liquid or solid is the Type 51 transducer end or for instruments in flange version, the instrument flange. Please note the information on the reference plane in chapter "3.3 Dimensions“. The max. filling depends on the required min.
Mounting and installation Therefore, in practical application, the transducer has to be oriented so that lowest possible false echo signal strength is achieved. Only giving attention to the size of the useful echo is usually not adequate under difficult measuring conditions. In most cases, a low false echo level enables the sensor to reliably pick up the useful echo. With the adjustment software VVO on the PC, you can view the echo image (see chapter "6.
Mounting and installation Reference plane £ 60 mm Reference plane £ 60 mm 1 /2 vessel radius Mounting on short 11/2“ or 2“ socket piece Dished tank ceiling On dished tank ceilings, please do not mount the instrument in the centre, but approx. 1/2 vessel radius from the centre. Dished tank ceilings can act as paraboloidal reflectors. If the transducer is placed at the focal point of the parabolic ceiling, the transducer receives amplified false echoes.
Mounting and installation Pump shaft 4.3 Measurement of solids Narrow, uneven shafts, wells and vessel openings with very rough walls and shoulders make ultrasonic measurement extremely difficult due to strong false echoes. This problem can be overcome by using an extended socket piece or a complete measuring tube (see chapter "4.5 Socket extension“). Flange mounting As with applications for liquids, the instrument can be mounted on a short DIN socket connection on vessels for solids.
Mounting and installation Different filling conditions often lead to a varying product surface orientation. This causes the useful echo to vary in quality. For this reason, the transducer should be mounted in such a way that, even in the empty vessel, the false echo intensity is as low as possible. You can view the echo curve on the PC with the adjustment program VVO (see chapter "6 Setup/Adjustment with the PC/Sensor optimisation/Echo curve“). ;;;;;;;;; Reference plane Min.
Mounting and installation Ultrasonic sensors require a min. distance to the product or solid. Take the min. distance into account in your planning. In some situations, it is possible to reach the required min. distance, and hence the desired filling height, with a socket extension. However, the socket extension increases the noise level of the ultrasonic signal at the extension outlet and can interfere with the measurement. Only use a socket extension if all other possibilities have to be excluded.
Mounting and installation The short examples on this page are only basic information on flow measurement. You can get complete planning information from the flume manufacturers and in special literature. - Installation of the sensor on the upstream side - Note distance to the overfall edge (3 … 4 x hmax) - Installation centered to the flume - Edge opening ³ 2 x hmax from ground - Installation perpendicular to the liquid surface - Keep min. distance in relation to hmax - Min.
Mounting and installation 4.6 False echoes Vessel installations The mounting location of the ultrasonic sensor must be selected such that no installations or inflowing material are in the path of the ultrasonic impulses. The following examples and instructions show the most frequent measuring problems and how to avoid them. Vessel installations such as, for example, a ladder, often cause false echoes.
Mounting and installation The expected max. high water determines the installation height, to ensure the min. distance of the transducer even with the highest water level. The low water basin ledges should be covered with a shield in the transducer area to filter out echoes from exposed basin surfaces. If the sensor is mounted too close to the vessel wall, buildup and adhesions of the measured product to the vessel wall can cause false echoes.
Mounting and installation 4.7 Incorrect mounting Strong heat fluctuations Foam generation Strong heat fluctuations, e.g. due to the sun, cause measuring errors. Please provide a sun shield. Thick foam on the product can cause incorrect measurements. Take measures to avoid foam, carry out the measurement in a bypass tube, or use a different measuring technology, e.g. capacitive measuring probes or hydrostatic pressure transmitters.
Mounting and installation If the sensor is mounted too close to the vessel wall (dimension A in diagram), strong false echoes can be caused. Buildup, rivets, screws or weld joints on the vessel wall superimpose their echoes to the product or useful echo. Please ensure the sufficient distance of the sensor to the vessel wall, depending on the maximum measuring distance (dimension B in diagram).
Mounting and installation Parabolic effects of rounded or arched vessel tops Round or parabolic tank tops act like a parabolic mirror on the signals. If the sensor is placed at the focal point of such a parabolic tank top, the sensor receives amplified false echoes. The optimum location is generally in the area of half the vessel radius from the centre. Socket piece too long If the sensor is mounted in a socket extension that is too long, strong false echoes are caused, and measurement is hindered.
Electrical connection 5 Electrical connection 5.1 Connection – Connection cable – Screening Safety information – Qualified personnel Instruments which are not operated with protective low voltage or DC voltage must only be connected by qualified personnel. This is also valid for the configuration of measuring systems planned for Ex environment. As a rule, do all connecting work in the complete absence of line voltage.
Electrical connection The distributed resistance of the cable, in conjunction with the output voltage of the segment coupler and the current requirement (VEGASON 10 mA) or the voltage requirement (VEGASON 9 V) of the sensor, determines the max. length of the cable. In practical application of a PA bus branch, the max. length of the cable is also determined (beside the required supply voltage and max.
Electrical connection In the so-called Fieldbus Intrinsically Safe Concept (FISCO) the general conditions for an Ex safe bus configuration have been laid down. Therein, the participants and the bus cables with their respective elec. data have been determined, so that the linking of these components always meets the Ex requirements. The more time-consuming Ex calculation normally required is therefore not necessary. Build your Ex bus according to the IEC standard 1158-2.
Electrical connection 5.2 Sensor address Hardware addressing In a Profibus system composed of Profibus DP and Profibus PA subsystem, each participant must have a unique address. Each participant, whether master or slave, is accessed by means of its own address in the bus system. The address of a participant, whether on DP or PA level, should be assigned before connecting to the bus, because an address can be used only once. If an address is used twice, interference will be caused in the bus.
Electrical connection Example 2 Software addressing You want to set address 27. 16 + 8 + 2 + 1 = 27 The DIP switches must be set to an address of 126 … 255, i.e. You must set the DIP switches 5 = 16 4=8 2=2 1=1 to "ON“. - either all DIP switches are set to "ON“, corresponding to address 255 (delivery status) - or only DIP switch 8 is set to "ON“, corresponding to address 128. Example 3 You want to set address 99 64 + 32 + 2 + 1 = 99 You must set the DIP switches 7 = 64 6 = 32 2=2 1=1 to "ON“.
Electrical connection 5.3 Connection of the sensor After mounting the sensor at the measurement location according to the instructions in chapter "4 Mounting and installation“, loosen the closing screws on top of the sensor. The sensor lid with the optional indication display can then be opened. Unscrew the sleeve nut and slip it over the connection cable (after removing about 10 cm of insulation). The sleeve nut of the cable entry has a self-locking ratchet that prevents it from opening on its own.
Electrical connection 5.4 Connection of the external indicating instrument Loosen the four screws of the housing lid on VEGADIS 50. The connection procedure can be facilitated by fixing the housing cover during connection work with one or two screws on the right of the housing.

Setup 6 Setup 6.1 Adjustment media Adjustment with PDM In chapter "1.4 Adjustment“ the Profibus adjustment structure was briefly explained and the adjustment media for VEGA Profibus sensors were shown.
Setup Segment coupler 6.2 Adjustment with VVO DP cable Before you can adjust the sensors with the adjustment program VVO (VEGA Visual Operating), they must be integrated into the Profibus system. First of all address the sensors (chapter "5.2 Sensor address“) and connect them to your PA segment. With the attached GSD file you integrate the sensors into your system.
Setup Configuration and parameter adjustment During setup of the sensor you will be confronted with two terms: "Configuration“ and "Parameter adjustment“. The measuring system is first configured and then made ready for operation by parameter adjustment. Configuration The term "Configuration“ means the basic adjustments of the meas. system. You inform the meas. system about the application (level measurement, gauge, distance …), the measurement loop name and the DCS output address of the sensors.
Setup The adjustment program VEGA Visual Operating (VVO), called in the following VVO, gets into contact with the connected sensor … … and asks in which mode the adjustment software should be used. After a few seconds, the software indicates if and with which system a connection exists. If the following message is displayed, you have to change the communication settings in VVO. • Then click to "Configuration“, point to "Program“ and click to " Communication“.
Setup • Click to "Planning“ and then to "OK“. Configuration The VVO software asks again for user identification and then reads in all VEGA Profibus sensors found. You now see the VVO main menu window. User identification The preadjusted user identification can be modified at a later time in the menu "Configuration/Program/User access“. Configuration info • Choose the menu "Configuration/Measuring system“. You reach the menu window "Configuration measuring system“.
Setup The measurement loops are listed as a sequence of sensor addresses with serial number and any existing name. • Choose in the window "Modify meas. loop configuration“ the application and enter a name for the measurement loop. If the sensor address has been adjusted with the DIP switch from 1 … 125, the address number in the field "Sensor address“ is grey and cannot be changed at this point. Parameter adjustment 1 Create new measurement loop • Choose the menu "Configuration/Measurement loop/Modify“.
Setup Adjustment • Click to the sensor or the measurement loop for which you want to carry out the parameter adjustment. • Then click to "OK“, the menu window " Instrument data parameter adjustment“ opens. • Click to "Adjustment“. Measurement loop data • Click in the menu window "Adjustment“ to "Min/Max-Adjustment“. • When clicking "Meas. loop data“, the most important measurement loop data will be displayed. You can carry out the min./max.
Setup • Choose "no (adjustment without medium)“. In the menu window "Min/Max-Adjustment“ you choose e.g. the level distance corresponding to 100 % and 0 %. Of course, you can also enter the distance values e.g. at 20 % and 75 % filling. If the two points are too close together, e.g. at 45 % and 49 %, this can cause a considerable meas. error, as the sensor generates by means of the two adjustment points a linear correlation between filling volume (%) and meas. distance.
Setup The sensor electronics has two characteristics points (at min. and max.) from which a linear proportionality between product distance and the percentage of filling of the vessel is generated. Of course, the characteristics points must not necessarily be at 0 % and 100 %, however they should be as far apart as possible (e.g. at 20 % and at 80 %). The difference between the characteristics points for the min./ max. adjustment should be at least 20 mm product distance.
Setup • Click to "Profibus output“. As physical unit you can choose "dimensionless (plain numbers), volume, mass, height and distance“ and assign an appropriate unit of measurement (e.g. l, hl). The sensor display then shows the measured value in the selected physical quantity and unit. • Save the adjustments in the menu "Profibus output“ with "OK“. In the window "Profibus output“ you can determine the options for the Profibus output (acc. to the Profibus PA instrument profile).
Setup Sensor optimisation In the menu "Sensor optimisation“ you prepare the sensor for the meas. environment. To do this, you carry out special optimising adjustments, like e.g. optimisation of the sensor mounting location by means of an echo curve. Meas. environment/Operating range • Choose the menu "Instrument data parameter adjustment“ and then the sensor. The window "Meas. environment“ opens. • Choose in the menu window "Instrument data parameter adjustment“ the menu item "Sensor optimisation.
Setup Meas. conditions/Sonic velocity In the menu item "Sonic velocity“ adjustments are only necessary when using the sensor in a gas composition deviating from air. If you measure in a gas composition deviating from air, e.g. pure nitrogen, the sonic velocity changes. Without correction, the measuring result would be incorrect. • Save the adjustments with "OK“ and you are again in the menu window "Meas. environment“. Meas. environment/Meas. conditions • Click in the menu window "Meas. ment“ to "Meas.
Setup Echo curve With the menu item "Echo curve“ in the menu window "Sensor optimisation“ you can see the course and the strength of the detected ultrasonic echo. If, due to vessel installations, you expect strong false echoes, a correction (if possible) of the mounting location and orientation (during simultaneous monitoring of the echo curve) can help localise and reduce the size of the false echoes.
Setup • Click to "Show echo curve. • Now click in the opening menu window "False echo storage“ to "Learn false echoes. A small window opens. The false echo marking and the real echo curve (top) are shown. • Quit the menu with • Enter here the verified product distance or the distance to the vessel bottom and click to "Create new. "Quit . You are again in the menu window "Sensor optimisation“. With the menu item "Reset“ you reset all options out of the menu "Sensor optimisation“ to default.
Setup Parameter adjustment 2 Linearisation The correlation between level and volume is defined by so-called linearisation curves. If there is a correlation in your vessel between level ("Percentage value“ of the level) and the volume (value of the volume) other than linear, choose in the menu window "Conditioning“ the menu item "Instrument data/Parameter adjustment/Conditioning“.
Setup 5.85 m meas. distance correspond to 0 % level. 1.27 m meas. distance correspond to 100 % level. The span is therefore 4.58 m (5.85 m – 1.27 m = 4.58 m). A percentage value of 95.79 % then means that 4.387 m of the adjusted span (4.58 m) have been reached: 4.58 • 0.9579 = 4.387 m. The user programmable linearisation curve is generated by index markers. Each index marker consists of a value pair. A value pair is generated from a value "Linearised“ and a value "Percentage value“.
Setup Index marker 1 is at 0 % filling (percentage value [%]), corresponding in the example to an actual distance to the product surface of 5.850 m (empty vessel). The volume is 45 liters (fluid remaining in the vessel). Index marker 2 is at a filling level of 30 % (30 % of the meas. distance of 1.270 m … 5.850 m). At a filling level of 30 %, there are 576 liters in the vessel (in our example). Index marker 3 is at a filling level of 60 %. At this filling level there are 646 liters in the vessel.
Setup You are again in the menu window "Tank calculation“. • Click to "OK “ to save the tank calculation. • Click to "Calculate“. You are again in the menu window "Linearisation -- user programmable curve --“. The volume percentages, with the corresponding level percentages, are shown. When clicking in the bottom left part of the menu window to "Show scaled values“, liters will be displayed according to the adjustment in the menu "Instrument data/Parameter adjustment/Conditioning/Scaling“.
Setup The menu window for the adjustment of the cylindrical tank opens. Above the information "All dimensions are internal dimensions“, you will find two fields with the percentage values 0 % and 100 %. Here you can shift the 100 % line or the 0 % line. In the example, the 100 % filling line was defined at a distance of 650 mm from the upper vessel edge (inside). • Choose the meas. unit, e.g. mm, that should apply to the entered vessel dimensions.
Setup There is a linear interpolation between the linearisation points. • Click to "OK“ and you are again in the menu window "Tank calculation“. • Again click in the menu window "Tank calculation“ to "OK“ and you are in the linearisation menu. The sensor then outputs the actual filling volume calculated from the entered vessel dimensions. Here the calculated linearisation curve is again outputted.
Setup Parameter adjustment sensor display In the menu item "Outputs“ you choose the scale and the unit in which your level should be displayed. • Choose in the main menu window "Instrument data parameter adjustment“ and then the menu item "Outputs“. • Click to "Save“ to save the adjustment. • If the adjustments should remain unchanged, click to "Quit “. • Click in the menu window "Outputs“ to "Quit“ and you are in the menu window "Instrument data parameter adjustment“.
Setup Simulation • Click to the menu "Diagnostics/Simulation“ and choose the measurement loop. The grey scroll bar becomes active. With this scroll bar you can change the measured value to any value in the range of -10 % … 110 % and thereby simulate the filling or emptying of the vessel. In the input box above the scroll bar you can enter any percentage value of filling. The menu window "Simulation of outputs“ opens.
Setup Print configuration and adjustments With the menu "View“ you can have the adjustments displayed in detail. • Click to "Services/Print“. Before printing the complete configuration of all sensors, you can view the individual pages and … Backup With the menu items "Services/Backup/Signal conditioning instruments“ and "Services/ Backup/Sensors“ you save the configurations and parameter adjustments of VEGASON and of any individual sensor.
Setup 6.3 Sensor adjustment with the adjustment module MINICOM Tank 1 m (d) 12.345 - + ESC OK In addition to the PC, you can adjust the sensors with the small, detachable adjustment module MINICOM directly in the sensor. With the adjustment module MINICOM, only the sensor-relevant adjustment such as e.g. scaling of the sensor display, operating range, meas. conditions, sensor display scaling or false echo storage are possible.
Setup Adjustment is only necessary if the measurement is made in gases deviating from air (CO2, He, etc.). When measuring in gases, sound the distance of the sensor to the product surface and enter this in the menu item "Measurement in gases“. The sensor can then take the modified (compared to air) sonic velocity in gases into account and output correct levels. You can carry out the adjustment with or without medium.
Setup + or OK – With the "+“ or " –“ key you can assign a level distance (example 5.85 m) to the previously adjusted percentage value. If you do not know the distance, you have to do a sounding. The adjusted product distance is written in the sensor and the display stops flashing. You thereby adjusted the lower product distance as well as the percentage filling value corresponding to the lower product distance.
Setup • Confirm with "OK“. If necessary, choose a decimal point. However, note that only max. 4 digits can be displayed. In the menu "prop. to“ you choose the physical quantity (mass, volume, distance…) and in the menu "Unit“ the physical unit (kg, l, ft3, gal, m3 …). Linearisation: Adjust ment Signal condit ioning In the menu you get important information on the signal quality of the product echo.
