4 Mounting 4 Mounting 4.1 General instructions Suitability for process conditions Make sure that all parts of the instrument in contact with the measured product, especially the sensor element, process seal and process fitting, are suitable for the existing process conditions such as process pressure, process temperature as well as the chemical properties of the medium. You can find the specifications in chapter "Technical data" in the or on the type label.
4 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. Remember that with all versions there is a minimum distance below the reference plane - the so-called dead band - in which measurement is not possible; this distance from reference plane to medium must not be underrun. The exact value of the dead band is stated in chapter "Technical data".
4 Mounting 1 2 3 4 100% 0% Fig. 4: Version B, C, D - Measuring range (operating range) and max. measuring distance 1 full (dead band) 2 empty (max. measuring distance) 3 Measuring range 4 Reference plane Pressure/Vacuum Gauge pressure in the vessel does not influence VEGASON 64. 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.
4 Mounting 3 Insert the transducer tube in the requested length from below into the swivelling holder 4 Fasten with screws (4); torque max. 10 Nm 5 Remove the plug from below out of the instrument housing and plug it into the socket of the transducer tube 6 Plug the electronics housing to the transducer tube. Do not squeeze any cables.
4 Mounting Mounting - Version C Version C is supplied in three parts: l l l Transducer Transducer cable electronics for wall mounting Assemble the version as follows: 1 Loosen the screws on the fixing ring (4) with a hexagon spanner (size 4), remove the transducer tube out of the swivelling holder 2 Mount the flange 3 Insert the transducer tube in the requested length from below into the swivelling holder 4 Fasten with screws (4); torque max.
4 Mounting 11 Secure screw (3) with lacquer or similar to ensure permanent tightness of the swivelling holder 12 Rotate the connection head in such a way that the cable entry points downwards (moisture can drain off). Fasten the cylinder with screws (5); torque max. 5 Nm 13 Insert the plug at the end of the transducer cable into the socket on the remote electronics 1 2 Fig.
4 Mounting 5 Plug the connection head to the transducer tube. Do not squeeze any cables. The cylinder is in the correct position, if the lower notch (2) of the transducer tube is no longer visible 4 1 3 2 Fig.
4 Mounting 4.3 Mounting instructions Mounting position When mounting VEGASON 64, keep a distance of at least 500 mm (19.69 in) to the vessel wall. If the sensor is installed in the center of dished or round vessel tops, multiple echoes can arise. These can, however, be suppressed by an appropriate adjustment (see chapter "Setup"). If you cannot keep this distance you should carry out a false echo storage before setup. This applies mainly if buildup on the vessel wall is expected.
4 Mounting In vessels with conical bottom it can be advantageous to mount the sensor in the center of the vessel, as measurement is then possible down to the lowest point of the vessel bottom. Fig. 11: Vessel with conical bottom Socket Preferably the transducer should be mounted without socket flush to the vessel top. If the reflective properties of the medium are good, you can mount VEGASON 64 on a socket piece. The socket end should be smooth and burr-free, if possible also rounded.
4 Mounting Vessel installations such as for example, ladders, limit switches, heating spirals, struts etc. can cause false echoes that interfere with the useful echo. Make sure when planning your measuring site that the ultrasonic signals have a "clear view" to the measured product. In case of existing vessel installations, a false echo storage should be carried out during setup.
4 Mounting Material heaps Large material heaps are best measured with several instruments, which can be mounted on e.g. traverse cranes. For this type of application it is advantageous to orient the sensor perpendicular to the bulk solid surface. Fig. 15: Transducers on traverse crane Inflowing medium Do not mount the instruments in or above the filling stream. Make sure that you detect the product surface, not the inflowing product. Fig.
4 Mounting Air turbulences If there are strong air currents in the vessel, e.g. due to strong winds in outdoor installations or air turbulence, e.g. by cyclone extraction you should mount VEGASON 64 in a standpipe or use a different measuring principle, e.g. radar or guided radar (TDR). Heat fluctuations Strong heat fluctuations, e.g. caused by the sun, can cause measurement errors. In this case, you should use a sun shield. Fig.
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 according to Foundation Fieldbus specification Tip: We recommend VEGA overvoltage arrester B63-32.
5 Connecting to power supply 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. The cable screens to the power supply unit and to the next distributor must be connected to each other and also connected to ground potential via a ceramic capacitor (e.g. 1 nF, 1500 V).

6 Set up with the indicating and adjustment module PLICSCOM 6.4 Setup procedure Parameter adjustment As VEGASON 64 is a distance measuring instrument, the distance from the sensor to the product surface is measured. To have the real product level displayed, an allocation of the measured distance to the percentage height must be made. To carry out this adjustment, the distance is entered with full and empty vessel. If these values are not known, an adjustment with the distance values, e.g.
6 Set up with the indicating and adjustment module PLICSCOM 5 Carrying out max. adjustment Save the settings with [OK] and move to "Max. adjustment" with [>]. Proceed as follows: Max. adjustment 100.00 % = 1.000 m(d) 2.000 m(d) Medium selection 1 Prepare the % value for editing with [OK] and set the cursor to the requested position with [->]. Set the requested percentage value with [+] and save with [OK]. The cursor jumps now to the distance value.
6 Set up with the indicating and adjustment module PLICSCOM Enter the requested parameter via the appropriate keys, save your settings and jump to the next menu item with the [->] key. Damping To suppress fluctuations in the measured value display, e. g. caused by an agitated product surface, a damping can be set. This time can be between 0 and 999 seconds. Keep in mind that the reaction time of the entire measurement will then be longer and the sensor will react to measured value changes with a delay.
6 Set up with the indicating and adjustment module PLICSCOM Proceed as follows: 1 Move from the measured value display to the main menu by pushing [OK]. 2 Select the menu item "Service" with [->] and confirm with [OK]. Now the menu item "False signal suppression" is displayed. 3 Confirm "False signal suppression - Change now" with [OK] and select in the below menu "Create new".
