It is particularly suitable for solids, but also good for liquids.
Product description homepage www.vega.com under "Services - Downloads Software - Profibus". There you can also find the appropriate certificates. In a PDM environment, an EDD (Electronic Device Description) is also required to enable the full range of sensor functions (also available as a download).A CD with the appropriate files can be ordered via e-mail under info@de. vega.com or by phone from one of the VEGA agencies under the order number "DRIVER.S". 3.
Mounting 4 Mounting 4.1 General instructions Materials, wetted parts Make sure that the wetted parts of VEGASON 66, especially the seal and process fitting, are suitable for the existing process conditions such as pressure, temperature etc. as well as the chemical properties of the medium. You will find specification in chapter "Technical data" in the "Supplement".
Mounting Measuring range The reference plane for the measuring range (version A) is the lower edge of the flange. The reference plane for versions B, C and D is the lower edge of the transducer. Make sure that for all versions a min. distance - the so called dead zone - below the reference plane is maintained in which a measurement is not possible. The exact value of the dead zone is stated in the "Technical data" in the "Supplement".

Low pressure or vacuum does, however, damp the ultrasonic pulses. This influences the measuring result, particularly if the level is very low. With pressures under 0.

Mounting 1 > 500 mm Fig. 8: Installation location 1 Reference plane In vessels with conical vessel bottom it can be advantageous to direct the sensor in the center of the vessel, as measurement is then possible down to the lowest point of the vessel bottom. Fig. 9: Vessel with conical bottom 28789-EN-060731 Socket VEGASON 66 - Profibus PA Preferably the transducer should be mounted without socket flush to the vessel top.
Mounting If the reflective properties of the medium are good, you can mount VEGASON 66 on a socket piece. The socket end should be smooth and burr-free, if possible also rounded. Carry out a false echo storage. Sensor orientation In liquids, direct the sensor as perpendicular as possible to the product surface to achieve optimum measurement results. Fig. 10: Orientation in liquids To optimally align the sensor to solid products, a swivelling holder can be implemented.
Mounting Agitators If there are agitators in the vessel, a false echo storage should be carried out with the agitators in motion. This ensures that the interfering reflections from the agitators are saved with the blades in different positions. Fig. 12: Agitators 28789-EN-060731 Material heaps Large material heaps are detected with several instruments, which can be mounted on e.g. traverse cranes. For this type of application, it is best to orient the sensor toward the solid surface. Fig.
Mounting Fig. 14: Inflowing medium Foam Through the action of filling, stirring and other processes in the vessel, dense foams which considerably damp the emitted signals may form on the product surface. If foams are causing measurement errors, the sensor should be used in a standpipe or, alternatively, the more suitable guided radar sensors (TDR) should be used. Guided radar is not influenced by foam generation and is particularly suitable for such applications.

Connecting to voltage supply 5 Connecting to voltage supply 5.1 Preparing the connection Note safety instructions Generally not 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 according to Profibus specification.
Connecting to voltage supply must be connected directly to the internal ground terminal. The ground terminal outside on the housing must be connected to the potential equalisation (low impedance). In systems without potential equalisation, connect the cable screen directly to ground potential at the power supply unit and at the sensor. In the connection box or T-distributor, the screen of the short stub to the sensor must not be connected to ground potential or to another cable screen.
Connecting to voltage supply 10 Tighten the compression nut of the cable entry, the seal ring must completely encircle the cable 11 Connect the lead cable for power supply in the same way acc. to the wiring plan, in addition connect the ground conductor to the inner ground terminal. 12 Screw the housing cover back on The electrical connection is hence finished.

Setup with the indicating and adjustment module PLICSCOM Medium selection Each product has different reflective properties. In addition, there are various interfering factors which have to be taken into account: agitated product surfaces and foam generation (with liquids); dust generation, material cones and echoes from the vessel wall (with solids). To adapt the sensor to these different conditions, you should first select in this menu item "Liquid" or "Solid".

Linearisation curve A linearization is necessary for all vessels in which the vessel volume does not increase linearly with the level - e.g. with a cylindrical or spherical tank - and the indication or output of the volume is required. Corresponding linearization curves are preprogrammed for these vessels.

Maintenance and fault rectification 8 Maintenance and fault rectification 8.1 Maintenance When used as directed in normal operation, VEGASON 66 is completely maintenance free. 8.2 Fault rectification Causes of malfunction VEGASON 66 offers maximum reliability. Nevertheless faults can occur during operation. These may be caused by the following, e.g.
Maintenance and fault rectification ? In Simatic S7 the measured value is always presented as 0 l Only four bytes are consistently loaded in the PLC à Use function component SFC14 to load 5 bytes consistently ? Measured value on the indicating and adjustment module does not correspond to the value in the PLC l The menu item "Display - Display value" is not set to "PA-Out" à Check values and correct, if necessary ? No connection between PLC and PA network l Incorrect adjustment of the bus parameter
Maintenance and fault rectification ? E017 l Adjustment span too small à Carry out a fresh adjustment and increase the distance between min. and max. adjustment ? E036 l no operable sensor software à Carry out software update or send instrument for repair ? E041 l Hardware error, electronics defective à Exchange instrument or return instrument for repair ? E113 l Communication conflict à Exchange instrument or return instrument for repair 8.
Maintenance and fault rectification Information: When loading on site, the order data must be downloaded from the Internet (see Operating Instructions manual "Oscillator").
