Its capacity to handle normal loads during transport is assured by a test based on ISO 4180. The packaging consists of environment-friendly, recyclable cardboard.
3 Product description Flanges 3.5 Accessories Screwed flanges are available in different versions according to the following standards: DIN 2501, EN 1092-1, BS 10, ASME B 16.5, JIS B 2210-1984, GOST 12821-80. Welded sockets and adapters Welded sockets are used to connect the sensors to the process. Mounting accessories The mounting accessories include e.g. bracket and mounting bracket and are used for stable mounting of the sensor at the measuring point.
4 Mounting 4 Mounting 4.1 General instructions Ambient conditions The instrument is suitable for standard and extended ambient conditions acc. to DIN/EN/IEC/ANSI/ISA/UL/CSA 61010-1. It can be used indoors as well as outdoors. Process conditions Note: For safety reasons, the instrument must only be operated within the permissible process conditions. You can find detailed information on the process conditions in chapter "Technical data" of the operating instructions or on the type label.
4 Mounting Polarisation 4.2 Mounting instructions Radar sensors for level measurement emit electromagnetic waves. The polarization is the direction of the electrical component of these waves. The polarization direction is marked on the housing, see following drawing: 1 Fig. 4: Position of the polarisation 1 Marking of the polarisation Note: When the housing is rotated, the direction of polarization changes and hence the influence of the false echo on the measured value.
4 Mounting Fig. 6: Mounting of the radar sensor on vessels with conical bottom Reference plane The lower side of the radar antenna is the beginning of the measuring range. It is at the same time the reference plane for the min./max. adjustment, see following diagram: 1 Fig. 7: Reference plane 1 58350-EN-191014 Inflowing medium Reference plane Do not mount the instruments in or above the filling stream. Make sure that you detect the product surface, not the inflowing product. Fig.
ca. 5 mm 4 Mounting Fig. 9: Thread mounting If the reflective properties of the medium are good, you can mount VEGAPULS 11 on sockets longer than the antenna. The socket end should be smooth and burr-free, if possible also rounded. h You will find recommended values for socket heights in the following illustration or the table. The values come from typical applications. Deviating from the proposed dimensions, also longer sockets are possible, however the local conditions must be taken into account.
4 Mounting Fig. 11: Cover flat, large-area profiles with deflectors Sensor orientation In liquids, direct the sensor as perpendicular as possible to the product surface to achieve optimum measurement results. Fig. 12: Alignment in liquids Agitators If there are agitators in the vessel, a false signal suppression 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.

5 Connecting to power supply 5 Safety instructions Connecting to power supply 5.1 Preparing the connection Always keep in mind the following safety instructions: • • Carry out electrical connection by trained, qualified personnel authorised by the plant operator If overvoltage surges are expected, overvoltage arresters should be installed Warning: Only connect or disconnect in de-energized state. Voltage supply The data for power supply are specified in chapter "Technical data".
5 Connecting to power supply You have to remove this plug before electrical connection. NPT thread In the case of instrument housings with self-sealing NPT threads, it is not possible to have the cable entry screwed in at the factory. The free opening for the cable gland is therefore covered with a red dust protection cap as transport protection. Note: Prior to setup you have to replace this protective cap with an approved NPT cable gland or close the opening with a suitable blind plug.
5 Connecting to power supply Fig. 16: Connection You can find further information on the max. wire cross-section under "Technical data - Electromechanical data". Connecting Connect the instrument as described in the following wiring plan. 5.3 Wiring plan Electronics and connection compartment (+)1 2(-) 1 1 20 Voltage supply, signal output VEGAPULS 11 • Two-wire 4 … 20 mA 58350-EN-191014 Fig.

6 Access protection 6 6.1 Access protection Bluetooth radio interface Devices with a Bluetooth radio interface are protected against unwanted access from outside. This means that only authorized persons can receive measured and status values and change device settings via this interface. Bluetooth access code A Bluetooth access code is required to establish Bluetooth communication via the adjustment tool (smartphone/tablet/notebook).
6 Access protection 58350-EN-191014 Emergency device unlock The emergency device unlock code allows unlocking the devices in code case the device code is no longer known. It can't be changed. The emergency device unlock code can also be found on the supplied information sheet "Emergency codes". If this document is lost, the emergency device unlock code can be retrieved from your VEGA contact person after legitimation.

Connecting … 7.
7 Setup with smartphone/tablet (Bluetooth) The message "Waiting for authentication" is displayed on the smartphone/tablet. Connected After connection, the sensor adjustment menu is displayed on the respective adjustment instrument. If the Bluetooth connection is interrupted, e.g. due to a too large distance between the two devices, this is displayed on the operating device. The message disappears when the connection is restored.
8 Setup with PC/notebook (Bluetooth) 8 System requirements 8.1 Preparations Make sure that your PC/notebook meets the following system requirements: • • • Activate Bluetooth connection Setup with PC/notebook (Bluetooth) Operating system Windows 10 DTM Collection 12/2019 or newer Bluetooth 4.0 LE or newer Activate the Bluetooth connection via the VEGA project assistant. Note: Older systems do not always have an integrated Bluetooth LE. In these cases, a Bluetooth USB adapter is required.
8 Setup with PC/notebook (Bluetooth) Note: If an incorrect code is entered, the code can only be entered again after a delay time. This time gets longer after each incorrect entry. The message "Waiting for authentication" is displayed on the PC/ notebook. Connected After connection, the sensor DTM appears. Change device code Parameter adjustment of the device is only possible if the parameter protection is deactivated.
