1 About this document 1 About this document 1.1 Function This operating instructions manual provides all the information you need for mounting, connection and setup as well as important instructions for maintenance and fault rectification. Please read this information before putting the instrument into operation and keep this manual accessible in the immediate vicinity of the device. 1.2 Target group This operating instructions manual is directed to trained qualified personnel.
2 For your safety 2 For your safety 2.1 Authorised personnel All operations described in this operating instructions manual must be carried out only by trained specialist personnel authorised by the plant operator. During work on and with the device the required personal protective equipment must always be worn. 2.2 Appropriate use The VEGAMIP 61 is a sensor for level detection. You can find detailed information on the application range in chapter "Product description".
2 For your safety The emitting frequencies of the sensors depend on the model, but are all in the K band range. The low transmitting power lies far below the internationally permitted limit value. When the instrument is used correctly, it presents no danger to human health. It may be operated without restriction outside of closed vessels. 2.5 CE conformity The device fulfills the legal requirements of the applicable EC guidelines. By attaching the CE mark, VEGA provides a confirmation of successful testing.
3 Product description 3 Product description 3.1 Configuration Type label The type label contains the most important data for identification and use of the instrument: l l l l Article number Serial number Technical data Article numbers, documentation With the serial number, you can access the delivery data of the instrument via www.vega.com, "VEGA Tools" and "serial number search". In addition to the type label outside, you can also find the serial number on the inside of the instrument.
3 Product description It works even under extremely difficult conditons, such as different granulation sizes, contamination, extreme filling noise, high temperatures, strong dust generation or abrasive products. The VEGAMIP 61 consists of the following components. 3 3 4 5 5 1 2 Fig.
3 Product description Several antenna versions are available for different applications. 1 2 3 4 Fig. 2: Antenna versions 1 2 3 4 Functional principle Encapsulated horn antenna with PTFE cover Plastic encapsulated antenna with PP cover Horn antenna VEGAMIP 61 with angled antenna extension The emitting unit transmits a focused microwave signal via horn antenna to the receiving unit on the opposite side. If there is medium between emitting and receiving unit, the signal is damped.
3 Product description Storage Up to the time of installation, the packages must be left closed and stored according to the orientation and storage markings on the outside.
3 Product description Mounting adapter With high process temperatures exceeding 80 °C, you have to use a mounting adapter for the emitting and receiving unit. The mounting adapter can be only used with the encapsulated horn antenna with PTFE cover. -EN-100531 Fig.
4 Mounting 4 Mounting 4.1 General instructions Screwing in With instruments with threaded process fitting, suitable tools must be applied for tightening the hexagon. Warning: The housing must not be used to screw the instrument in! Applying tightening force can damage internal parts of the housing. Suitability for the process conditions Make sure that all parts of the instrument exposed to the process, in particular the antenna, seal and process fitting, are suitable for the existing process conditions.
4 Mounting Avoid mounting the instrument too close to the vessel wall. Reflections from the vessel wall or from vessel installation can influence the switching accuracy. Fig. 4: Installation position (top view) Inflowing medium If VEGAMIP 61 is mounted in the filling stream, unwanted false measurement signals can be generated. For this reason, mount VEGAMIP 61 at a position in the vessel where no disturbances, e.g. from filling openings, agitators, etc., can occur.
4 Mounting 1 Fig. 6: Installation in front of a vessel window 1 Window of non-conductive material, for example, glass, plastic, etc. Concrete vessel In general, the same as for metal vessels applies to concrete vessels due to the steel braining. Wood vessels In general, the same as for metal vessels applies to wood vessels due to the liquid absorption of the wood. Pipelines VEGAMIP 61 can be used for detection of products in pipelines.

4 Mounting 1 2 Fig. 9: Front-flush installation 1 2 Unfavourable installation - bulk solid can settle in front of the sensor Correct front flush installation Abrasive medium In very abrasive products, VEGAMIP 61 should be installed with a mounting adapter or in front of a suitable window. In this case, you have to use a window material which is appropriately resistant. Orientation of the sensor For an optimum switching signal, the two sensors must be adapted to each other.
4 Mounting + - 5° Fig. 10: Orientation of the sensors The emitting unit emits electromagnetic waves. The polarisation plane is the direction of the electrical wave component. Its position is marked on the instrument hexagon by polarisation markings. For a reliable function, the emitting and receiving unit must be installed in the same polarisation direction.
4 Mounting Special mounting options In tight mounting spaces or spaces subject to high temperatures, the signal of VEGAMIP 61 can be guided via a deflector. You can use a metal plate for this or an angled antenna extension on the side of the emitting unit. In products with low dielectric value, we recommend using an instrument version with antenna extension because it focusses the signal optimally and has no signal loss.
5 Connecting to power supply 5 Connecting to power supply 5.1 Preparing the connection Safety instructions Always keep in mind the following safety instructions: l l Voltage supply Connect only in the complete absence of line voltage If overvoltages are expected, install overvoltage arresters Connect the operating voltage according to the following diagrams. The oscillator with relay output is designed in protection class 1.
5 Connecting to power supply 4 Insert the cable into the sensor through the cable entry Fig. 13: Connection steps 4 and 5 5 Insert the wire ends into the terminals according to the wiring plan Information: Solid cores as well as flexible (stranded) cores with wire end sleeves are inserted directly into the terminal openings. If you are using flexible cores without end sleeves, press with a small screwdriver on the terminal, the terminal opening is freed.
5 Connecting to power supply 5.3 Wiring plan, single chamber housing Wiring plan We recommend connecting VEGAMIP 61 in such a way that the switching circuit is open when there is a level signal, line break or failure (safe condition). Information: The relays are always shown in non-operative condition. 3 2 1 Fig.

7 Maintenance and fault rectification 7 Maintenance and fault rectification 7.1 Maintenance When the device is used correctly, no maintenance is required in normal operation. 7.2 Rectify malfunctions Reaction when malfunctions occur The operator of the system is responsible for taking suitable measures to remove interferences. Fault rectification The first measure to be taken is to check the output signal. In many cases, the causes can be determined this way and the faults rectified.
7 Maintenance and fault rectification Reaction after fault rectification Depending on the failure reason and measures taken, the steps described in chapter "Set up" must be carried out again, if necessary. 24 hour service hotline However, should these measures not be successful, call the VEGA service hotline in urgent cases under the phone no. +49 1805 858550. The hotline is available to you 7 days a week round-the-clock.
8 Dismounting 8 Dismounting 8.1 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. 8.2 Disposal The instrument consists of materials which can be recycled by specialised recycling companies.
