3 Product description • Enter the serial number manually in the app Scope of this operating instructions manual This operating instructions manual applies to the following instrument versions: Versions The instrument and the electronics version can be determined via the product code on the type label as well as on the electronics. • • • • Hardware from 1.0.0 Software from 1.0.0 DTM from version 1.67.2 Standard electronics: Type FX80H.
3 Product description Between a dielectric constant of 1.5 and 3, the function switches on, if required. As soon as the level echo can no longer be detected, probe end tracking is automatically activated. The measurement is continued with the last calculated dielectric constant. The accuracy thus depends on the stability of the dielectric constant. If you measure a medium with a dielectric constant below 1.5, probe end tracking is always active.
3 Product description VEGACONNECT The interface adapter VEGACONNECT enables the connection of communication-capable instruments to the USB interface of a PC. For parameter adjustment of these instruments, the adjustment software PACTware with VEGA-DTM is required.

4 Mounting 4 Screwing in Mounting 4.1 General instructions On instruments with process fitting thread, the hexagon must be tightened with a suitable screwdriver. Wrench size see chapter "Dimensions". Warning: The housing must not be used to screw the instrument in! Applying tightening force can damage internal parts of the housing.
4 Mounting vessels, the distance to the vessel wall should be at least 500 mm (19.7 in). During operation, the probe must not touch any installations or the vessel wall. If necessary, fasten the probe end. In vessels with conical bottom it can be advantageous to mount the sensor in the center of the vessel, as measurement is then possible nearly down to the lowest point of the bottom. Keep in mind that measurement all the way down to the tip of the probe may not be possible. The exact value of the min.
4 Mounting 1 2 Fig. 6: Installation in non-metallic vessel 1 2 Flange Metal sheet Concrete vessel When installed in thick concrete ceilings, VEGAFLEX 82 should be mounted front flush to the lower edge. In concrete silos, the distance to the wall should be at least 500 mm (20 in). ø >160 mm (ø >6.3") Socket 16 If possible, avoid sockets. Mount the sensor flush with the vessel top. If this is not possible, use short sockets with small diameter.
4 Mounting Higher sockets or sockets with a bigger diameter can generally be used. They can, however, increase the upper blocking distance (dead band). Check if this is relevant for your measurement. In such cases, always carry out a false signal suppression after installation. You can find further information under "Setup procedure". d d h _ 150 < _ 100 < h DN40 ... DN150 > DN150 ... DN200 Fig. 8: Mounting socket When welding the socket, make sure that the socket is flush with the vessel top.
4 Mounting Fig. 10: Mounting of the sensor with inflowing medium Measuring range The reference plane for the measuring range of the sensors is the sealing surface of the thread or flange. Keep in mind that a min. distance must be maintained below the reference plane and possibly also at the end of the probe - measurement in these areas is not possible (dead band). The length of the cable can be used all the way to the end only when measuring conductive products.
4 Mounting 1 1 2 2 Fig. 11: Fasten the probe 1 2 Lateral installation Probe Retaining sleeve In case of difficult installation conditions in liquid applications, the probe can be also mounted laterally. For this purpose, adapt the rod with rod extensions or bow-shaped segments. Let the probe length determine automatically by the instrument to compensate the resulting running time changes. The determine probe length can deviate from the actual probe length when using bow-shaped segments.
5 Connecting to power supply 5 Safety instructions Voltage supply Connecting to power supply 5.1 Preparing the connection Always keep in mind the following safety instructions: • • Connect only in the complete absence of line voltage If overvoltage surges are expected, overvoltage arresters should be installed Power supply and current signal are carried on the same two-wire cable. The operating voltage can differ depending on the instrument version.
5 Connecting to power supply suppressed, but the protective effect against high frequency interference signals remains. Cable screening and grounding with potential differences Considerable potential differences exist inside galvanic plants as well as vessels with cathodic corrosion protection. Warning: Very large equalisation currents can flow through the cable screen when the screen is grounded on both ends.

6 Functional safety (SIL) 6 Functional safety (SIL) 6.1 Objective In case of dangerous outages, processing facilities and machines can cause risks for persons, environment and property. The risk of such outages must be judged by the plant operator. Dependent thereon are measures for risk reduction through error prevention, error detection and fault control. The part of plant security depending on the correct functioning of safety-related components for risk reduction is called functional safety.
6 Functional safety (SIL) • Tool for operation and parameterization 4 … 20 mA current output 6.4 Safety concept of the parameterization The following tools are permitted for parameterization of the safety function: • • The integrated display and adjustment unit for on-site adjustment The DTM suitable for the signal conditioning instrument in conjunction with an adjustment software according to the FDT/DTM standard, e. g. PACTware Note: For operation of the VEGAFLEX 82 the DTM Collection version 1.
6 Functional safety (SIL) Change parameter All parameters changed by the operator are automatically stored temporarily so that they can be verified in the next step. Verify parameters/Lock adjustment After setup, the modified parameters must be verified (confirm the correctness of the parameters). To do this, you first have to enter the PIN. Here the adjustment is locked automatically. Then you carry out a comparison of two character strings. You must confirm that the character strings are identical.
6 Functional safety (SIL) Setup is then finished. Function test required Should a function test be necessary, the following message is displayed on the display and adjustment module. The adjustment software also signals that a function test is required. If a function test is required, the switching point or the range must be controlled with the original medium. For this purpose, you have to decide for your application which condition is potentially critical.
6 Functional safety (SIL) Measure the current output and compare the value with the calculated current value. You have to determine the permissible deviation of the values yourself. This deviation depends on the the accuracy requirements of your measurement loop. Determine the permissible tolerance for the deviation. Mode "Range monitoring" If both levels are important for the safety function, you have to proceed according to the mode "Range monitoring". 1.

7 Set up with the display and adjustment module • • • –– Confirm selected menu –– Edit parameter –– Save value [->] key: –– Presentation, change measured value –– Select list entry –– Select editing position [+] key: –– Change value of the parameter [ESC] key: –– Interrupt input –– Jump to next higher menu Adjustment system The sensor is adjusted via the four keys of the display and adjustment module. The LC display indicates the individual menu items.
7 Set up with the display and adjustment module Setup: Settings, e.g. measurement loop name, medium, vessel, adjustment, signal output, device unit, false signal suppression, linearization curve Display: Settings, e.g., for language, measured value display, lighting Diagnosis: Information, e.g.
7 Set up with the display and adjustment module correctly. If necessary, other measures must be taken to maintain the safety function. Setup - Measurement loop name Here you can assign a suitable measurement loop name. Push the "OK" key to start the processing. With the "+" key you change the sign and with the "->" key you jump to the next position. You can enter names with max. 19 characters.
7 Set up with the display and adjustment module You have the option of choosing the demonstration mode. In this mode, the sensor ignores the parameters of the application and reacts immediately to any change. This mode is only suitable for test and demonstration purposes and must not be used in a safety-instrumented application (SIL). Setup - Medium, dielectric constant In this menu item, you can define the medium type (product).
7 Set up with the display and adjustment module Adjust the requested percentage value with [+] and store with [OK]. Enter the suitable distance value in m for the empty vessel (e.g. distance from the flange to the probe end) corresponding to the percentage value. The distance refers tot he sensor reference plane (seal surface of the process fitting). Setup - Damping To damp process-dependent measured value fluctuations, set an integration time of 0 … 999 s in this menu item.
7 Set up with the display and adjustment module D -h +h For the socket correction you have to enter the height of the socket above the upper edge of the vessel. If the socket is lower than the upper edge of the vessel, this value can also be negative. Fig. 27: Vessel height und socket correction value D Vessel height +h Positive socket correction value -h Negative socket correction value Since scaling is very extensive, scaling of the level value was divided into two menu items.
7 Set up with the display and adjustment module Setup - Scaling Level 2 Since scaling is very extensive, scaling of the level value was divided into two menu items. In menu item "Level 2" you define the scaling format on the display and the scaling of the measured level value for 0 % and 100 %. Setup - Current output Size In menu item"Current output, size" you determine which measured value the current output refers to.
7 Set up with the display and adjustment module The default setting is min. current 3.8 mA and max. current 20.5 mA. Setup - Current output 2 If a supplementary electronics with a second current output is implemented in the instrument, then you can adjust the second current output separately. In menu item"Current output 2" you specify which measured value the second current output refers to. The second current output cannot be used as an output in the sense of a safety-instrumented application (SIL).
7 Set up with the display and adjustment module Note: A false signal suppression is only recommended with liquid applications. A false signal suppression detects, marks and saves these false signals so that they are no longer taken into account for level measurement. This should be done with the lowest possible level so that all potential interfering reflections can be detected. Proceed as follows: Enter the actual distance from the sensor to the product surface.
7 Set up with the display and adjustment module For this reason, the instrument is shipped in locked conditon. The PIN in the delivery status is "0000". Character string comparison and serial number You first have to carry out the character string comparison. This is used to check the character respresentation. Confirm if the two character strings are identical. The verification texts are provided in German and with all other menu languages in English.
7 Set up with the display and adjustment module Verify parameter All safety-relevant parameters must be verified after a change. After the function test, all modified, safety-relevant parameters will be listed. Confirm the modified values one after the other. If the described process of parameter adjustment was run through completely and correctly, the instrument will be locked and hence ready for operation. Otherwise the instrument remains in the released and hence unsafe condition.
7 Set up with the display and adjustment module Display - Displayed value 1 In this menu item, you define the indication of the measured value on the display. You can display two different measured values. In this menu item, you define measured value 1. The default setting for the displayed value 1 is "Filling height Level". Display - Displayed value 2 In this menu item, you define the indication of the measured value on the display. You can display two different measured values.
7 Set up with the display and adjustment module Diagnostics - Peak values The respective min. and max. measured values are saved in the Measurement certainty sensor. The two values are displayed in the menu item "Peak values, measurement certainty". The measurement can be influenced by the process conditions. In this menu item, the measurement certainty of the level measurement is displayed as percentage value. The higher the value, the more reliable the measurement.
7 Set up with the display and adjustment module Diagnosis - Simulation In this menu item you can simulate measured values via the current output. This allows the signal path to be tested, e.g. via downstream indicating instruments or the input card of the control system. Select the requested simulation size and adjust the requested value. Caution: During simulation, the simulated value is outputted as 4 … 20 mA current value and digital HART signal. Push the [ESC] key to deactivate the simulation.
7 Set up with the display and adjustment module Diagnosis - Proof test With the function "Proof test", the function of the instrument can be checked on a recurring basis. During the function test, the safety function must be treated as unsafe. Keep in mind that the function test influences downstream connected devices. You can find detailed information on the proof test in the Safety Manual (SIL).
7 Set up with the display and adjustment module signal suppression, user-programmable linearization curve as well as the measured value memory will be deleted. Basic settings: Resetting of the parameter settings incl. special parameters to the default values (presettings) of the respective instrument. Any created false signal suppression or user-programmable linearization curve as well as the measured value memory are deleted. The following tables show the default values of the instrument.
