3 Product description Application area 3.2 Principle of operation VEGASWING 61 is a point level sensor with tuning fork for level detection. It is designed for industrial use in all areas of process technology and can be used in liquids. Typical applications are overfill and dry run protection. With its tuning fork of only 40 mm length, VEGASWING 61 can also be mounted e.g. in pipelines from DN 32. The small tuning fork allows use in vessels, tanks and pipes.
3 Product description • Packaging Mode adjustment for selection of the switching condition (A/B) 3.4 Storage and transport Your instrument was protected by packaging during transport. Its capacity to handle normal loads during transport is assured by a test according to DIN EN 24180. The packaging of standard instruments consists of environmentfriendly, recyclable cardboard. The sensor is also equipped with a protective cap of ABS. For special versions, PE foam or PE foil is also used.
4 Mounting 4 Mounting 4.1 General instructions Suitability for the process Make sure that all parts of the instrument coming in direct contact with conditions the process, especially the sensor element, process seal and process fitting and suspension cable, 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" and on the type plate.
4 Mounting 1 Fig. 3: Mounting horizontal 1 Switching point 2 1 Fig. 4: Horizontal installation (recommended mounting position, particularly for adhesive products) 1 2 Switching point Marking with screwed version on top, with flange versions directed to the flange holes With flange versions, the fork is directed as follows to the flange holes. Fig. 5: Fork position with flange versions Moisture Use the recommended cables (see chapter "Connecting to power supply") and tighten the cable gland.
4 Mounting Fig. 6: Measures against moisture penetration Transport Caution: Do not hold VEGASWING 61 on the tuning fork. Particularly with flange or tube versions, the tuning fork can be damaged just by the weight of the instrument. Transport coated instruments very carefully and avoid touching the tuning fork. Remove the packaging or the protective cover just before installation. Pressure/Vacuum The process fitting must be sealed if there is gauge or low pressure in the vessel.
4 Mounting 1 Fig. 7: Marking on the welded socket 1 Adhesive products Marking In case of horizontal mounting in adhesive and viscous products, the surfaces of the tuning fork should be vertical in order to reduce buildup on the tuning fork. On the screwed version you will find a marking on the hexagon. With this, you can check the position of the tuning fork when screwing it in. When the hexagon touches the seal, the thread can still be turned by approx. half a turn.
5 Connecting to power supply 5 Note safety instructions Take note of safety instructions for Ex applications 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 In hazardous areas you must take note of the respective regulations, conformity and type approval certificates of the sensors and power supply units.
5 Connecting to power supply 8. Check the hold of the wires in the terminals by lightly pulling on them 9. Tighten the compression nut of the cable entry. The seal ring must completely encircle the cable 10. Screw the housing cover back on The electrical connection is hence finished. 5.3 Housing overview Wiring plan, single chamber housing The following illustrations apply to the non-Ex as well as to the Ex-d version. 4 4 1 4 2 3 Fig.
5 Connecting to power supply Wiring plan We recommend connecting VEGASWING 61 in such a way that the switching circuit is open when there is a level signal, line break or failure (safe condition). The instrument is used to control relays, contactors, magnet valves, warning lights, horns as well as PLC inputs. Caution: There is no reverse polarity protection. Take note of the polarity of the output lines. - + 1 2 3 4 + - Fig. 10: NPN action - + 1 2 3 4 + - Fig.
6 Setup 6 Setup 6.1 General information The figures in brackets refer to the following illustrations. Function/Configuration With plastic housings, the switching condition of the electronics can be checked when the housing cover is closed (control lamp). With the basic setting, products with a density > 0.7 g/cm³ (0.025 lbs/in³) can be detected. For products with lower density, the switch must be set to > 0.5 g/cm³ (0.018 lbs/in³).
6 Setup "Function chart" (A - max. detection or overflow protection, B - min. detection or dry run protection). Sensitivity adjustment (3) With this DIL switch (3) you can set the switching point to liquids having a density between 0.5 and 0.7 g/cm³ (0.018 and 0.025 lbs/ in³). With the basic setting, liquids with a density of > 0.7 g/cm³ (0.025 lbs/in³) can be detected. In liquids with lower density, you must set the switch to > 0.5 g/cm³ (0.018 lbs/in³).

7 Maintenance and fault rectification 7 Maintenance and fault rectification 7.1 Maintenance 7.2 Rectify faults If the instrument is used properly, no special maintenance is required in normal operation. Reaction when malfunctions occur The operator of the system is responsible for taking suitable measures to rectify faults. Failure reasons VEGASWING 61 offers maximum reliability. Nevertheless, faults can occur during operation. These may be caused by the following, e.g.
7 Maintenance and fault rectification Checking the switching signal Error Cause VEGASWING 61 signals Operating voltage too "covered" without being low submerged (overfill proElectronics defective tection) VEGASWING 61 signals "uncovered" when being submerged (dry run protection) Rectification Check operating voltage Press the mode switch. If the instrument then changes the mode, the vibrating element may be covered with buildup or mechanically damaged.
7 Maintenance and fault rectification You find all information to the electronics exchange in the operating instructions of the new electronics module. In general, all electronics modules of series SW60 can be interchanged. If you want to use an electronics module with a different signal output, you carry out the complete setup. You find the necessary, suitable operating instruction on our homepage. Note: Keep in mind that enamelled instrument versions need special electronics modules.
8 Dismounting 8 8.1 Dismounting 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. With Ex instruments, the housing cover may only be opened if there is no explosive atmosphere present. 8.
