1 About this document 1 About this document 1.1 Function 1.2 Target group 1.3 Symbols used This instruction provides all the information you need for mounting, connection and setup as well as important instructions for maintenance, fault rectification, the exchange of parts and the safety of the user. Please read this information before putting the instrument into operation and keep this manual accessible in the immediate vicinity of the device.
2 For your safety 2 2.1 For your safety Authorised personnel All operations described in this documentation must be carried out only by trained, qualified 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 VEGAPULS Air 23 is an autarkic sensor for continuous level measurement in plastic vessels.
2 For your safety 2.5 Lithium cells The power supply of the device is provided by integrated lithium cells in the housing. If the device is used as intended with the lid closed within the temperatures and pressures specified in the technical data, it is thus adequately protected. Note: Please observe the specific safety instructions in the scope of delivery of the device. 2.

3 Product description Constituent parts 5 4 3 2 1 Fig. 1: Components of the VEGAPULS Air 23 sensor (example version for adhesive joint) 1 2 3 4 5 Radar antenna Unscrewable mounting ring with glue surface Eyelets for transport lock Housing lid Contact surface for activation by NFC or magnet The type plate contains the most important data for identification and use of the device. This is located on the sensor housing.
3 Product description Measured value transmis- Depending on the availability of the radio networks, the device transsion mits its measured values wirelessly to an LTE-M (LTE-CAT-M1) or NBIoT (LTE-CAT-NB1) mobile radio or a plant-side LoRaWAN network. The transmission or evaluation is carried out via an Asset Management System, e.g. VEGA Inventory System. Voltage supply The device is supplied with energy by non-exchangeable primary cells.
4 Mounting 4 4.1 Mounting 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 300 mm (11.82") 130 mm (5.12") 480 mm (18.90") 150 mm (5.91") 100 mm (3.94") 50 mm (1.97") 1 2 3 4 5 Fig. 4: Mounting position on the tank ceiling 1 2 3 4 5 Recommended mounting position Permissible mounting range Filling opening Cross strut Vessel edge To avoid air bubbles in the area of the adhesive surface, the selected mounting position should be as flat as possible or slightly curved outwards.
4 Mounting Caution: The cleaning cloth supplied must not be used for chemical residues on the surface. Ask the chemical manufacturer for cleaning options. It is not possible to mount the sensor on a surface that has not been cleaned. Glued connection 4.4 Installation procedure The device version for adhesive bonding has a mounting ring with adhesive surface on the lower side of the housing. Proceed as follows: 1. Completely remove the protective foil on the glue surface immediately before mounting 2.
4 Mounting Transportation lock 4.5 Transportation lock after mounting The adhesive joint and the flexible mounting of the device are only designed for stationary operation of the vessel. 64314-EN-201215 Danger: During transport the vessel is exposed to vibrations and shocks. This can cause the device to fall down with the risk of damage to property or persons. To avoid this, the device must be additionally secured using the integrated safety eyelets on the vessel, e.g. with a metal wire.
5 Setup Activation 5 Setup The following options are available for activating the device from the deactivated delivery status: • • By smartphone with VEGA Tools app via NFC Via magnet Note: The device is intended for permanent use. Deactivation is therefore only possible by service intervention in the power supply. Please take this into account before activation. By smartphone Proceed as follows for activation by NFC: 1. Start VEGA Tools app on smartphone 2. Activate NFC communication 3.
5 Setup N AC IO AT TIV t ne ag M Fig. 6: Activate the sensor 1 2 3 Radar sensor Contact surface for magnet Magnet Setup is now complete and the unit is ready for operation. Measuring mode After activation, a single measurement is carried out and the cyclic measuring interval is started. The sensor delivers the distance value from the lower side of the antenna to the medium surface.
5 Setup The procedure is done by reactivating NFC as described above. The sensor is simultaneously activated for the cyclical transmission of measured values. The transmission cycle of an already activated sensor is not changed by this. Position determination The position is determined by an integrated GNSS sensor via navigation satellites. It is optionally available for the LTE-M/NB-IoT version of the device.
6 Diagnostics and servicing 6 Maintenance Cleaning Diagnostics and servicing 6.1 Maintenance If the device is used properly, no special maintenance is required in normal operation. The cleaning helps that the type label and markings on the instrument are visible.
6 Diagnostics and servicing 6.3 How to proceed if a repair is necessary You can find an instrument return form as well as detailed information about the procedure in the download area of our homepage. By doing this you help us carry out the repair quickly and without having to call back for needed information.
7 Removal with glue connection 7 Removal with glue connection 7.1 Dismounting instructions The device can be removed from the surface of an IBC container by unscrewing the sensor housing from the mounting ring. The mounting ring with its adhesive connection remains on the surface of the vessel and can be used for remounting the sensor. If the mounting ring should be removed, follow the mounting steps in the next section. 3 2 1 Fig.
7 Removal with glue connection 1. Place strap wrench around the mounting ring 2. Twist the mounting ring with the strap wrench, the adhesive bond is dissolved without any major force application. 3. Remove adhesive residues completely using a wooden scraper and dispose of in accordance with local regulations 7.3 Disposal The device is made of recyclable materials. For this reason, it should be disposed of by a specialist recycling company. Observe the applicable national regulations.
8 Certificates and approvals 8 8.1 Certificates and approvals Radio licenses Radar The device has been tested and approved in accordance with the current edition of the applicable country-specific norms or standards. Regulations for use can be found in the document " Regulations for radar level measuring instruments with radio licenses" on our homepage.
