3 Product description It is designed for industrial use in all areas of process technology and can be used in liquids. Functional principle High frequency microwave impulses are guided along a steel cable or rod or a rod inside a steel tube. When reaching the product surface, a part of the microwave impulses is reflected. The other part passes the upper product and is reflected a second time by the interface. The running times to the two product layers are processed by the instrument.

The analogue output (4 … 20 mA) transmits the height of the interface (h1) in percent. This is also the value that is adjusted.
3 Product description The background lighting of the indicating and adjustment module is powered by the sensor. A certain level of operating voltage is required for this. You can find the exact voltage specifications in chapter "Technical data". 3.3 Operation The instrument can be adjusted with the following adjustment media: l l l l With indicating and adjustment module with the suitable VEGA DTM in conjunction with an adjustment software according to the FDT/DTM standard, e.g.
4 Mounting 4 Mounting 4.1 General instructions Suitability for the process conditions Make sure that all parts of the instrument exposed to the process, in particular the sensor element, process seal and process fitting, are suitable for the existing process conditions. These include above all the process pressure, process temperature as well as the chemical properties of the medium. You can find the specifications in chapter "Technical data" and on the type label.
4 Mounting Fig. 3: Measures against moisture penetration 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). Particularly the cable length cannot be used all the way to the end because measurement in the area of the gravity weight is not possible. These min.
4 Mounting keep in mind that measurement down to the tip of the probe is not possible. The exact value of the min. distance (lower dead band) is stated in chapter "Technical data". Fig. 4: Vessel with conical bottom Inflowing medium Make sure that the probe is not subjected to strong lateral forces. Mount VEGAFLEX 67 at a position in the vessel where no disturbances, e.g. from filling openings, agitators, etc., can occur. Extreme vibration caused by the system, e.g.
4 Mounting more than 1 m (3.281 in) length, you must secure the probe by fastening a suitable insulated brace or guy directly above the end of the rod. Fixing If there is a danger of the probe touching the vessel wall during operation due to product movements or agitators etc., the measuring probe should be securely fixed. In the gravity weight there is a thread (M12), e.g. for a ring bolt (optional) - (article no. 2.27424). Make sure that the probe cable is not completely taut.
5 Connecting to power supply 5 Connecting to power supply 5.1 Preparing the connection Note safety instructions Always keep in mind the following safety instructions: l l Connect only in the complete absence of line voltage If overvoltage surges are expected, overvoltage arresters should be installed Tip: We recommend using VEGA overvoltage arresters B63-48 and ÜSB 62-36G.X.
5 Connecting to power supply If potential equalisation currents are expected, the connection on the processing side must be made via a ceramic capacitor (e. g. 1 nF, 1500 V). The low frequency potential equalisation currents are thus suppressed, but the protective effect against high frequency interference signals remains. Warning: Within galvanic plants as well as vessels with cathodic corrosion protection there are considerable potential differences.
5 Connecting to power supply 6 Insert the wire ends into the open terminals according to the wiring plan 7 Press down the opening levers of the terminals, you will hear the terminal spring closing 8 Check the hold of the wires in the terminals by lightly pulling on them 9 Connect the screen to the internal ground terminal, connect the outer ground terminal to potential equalisation 10 Tighten the compression nut of the cable entry.

8 Maintenance and fault rectification 8 Maintenance and fault rectification 8.1 Maintenance If the instrument is used properly, no special maintenance is required in normal operation. 8.2 Remove interferences Failure reasons VEGAFLEX 67 offers maximum reliability. Nevertheless, faults can occur during operation. These may be caused by the following, e.g.
8 Maintenance and fault rectification Error Cause Rectification Electronics moCurrent signal Exchange the instrument or send it in greater than 22 mA dule in the sensor for repair defective or less than 3.6 mA In Ex applications, the regulations for the wiring of intrinsically safe circuits must be observed. Error messages via the indicating and adjustment module The indicating and adjustment modules indicates faults via error codes and text messages.
8 Maintenance and fault rectification l l At the factory by VEGA Or on site by the user In both cases, the sensor serial number is necessary. The serial numbers are stated on the type label of the instrument, inside the housing or on the delivery note. Information: When loading on site, first of all the order data must be downloaded from the Internet (see operating instructions manual "Electronics module").
8 Maintenance and fault rectification Load software into sensor Select with the right mouse key the sensor in the project and go to "Additional function". Then click to "Software update". The window "Sensor # software update" opens. PACTware checks now the sensor data and displays the actual hardware and software version of the sensor. This takes approximately 60 s. Push the button "Update software" and select the previously extracted hex file. Then the software update can be started.
9 Dismounting 9 Dismounting 9.1 Dismounting steps Warning: Before dismounting, be aware of dangerous process conditions such as e.g. pressure in the vessel, high temperatures, corrosive or toxic products etc. Take note of chapters "Mounting" and "Connecting to power supply" and carry out the listed steps in reverse order. 9.2 Disposal The instrument consists of materials which can be recycled by specialised recycling companies.
