2 0 1 2 1 5 Functional principle The measurement is carried out through a suitable nozzle opening on the vessel. 8 VEGAPULS Air 41 Autarkic device with measured value transmission via radio technology 3 Product description The instrument emits a continuous, frequency-modulated radar signal through its antenna. The emitted signal is reflected by the medium and received by the antenna as an echo with modified frequency. The frequency change is proportional to the distance and is converted into the level. The measured value is transmitted wirelessly as part of the data transmission. The measuring cycle described above is time-controlled via the integrated clock. Outside of the measuring cycle, the device is in a sleep mode. Measured value transmis-

sion Depending on the availability of the radio networks, the device trans-

mits its measured values wirelessly to an LTE-M (LTE-CAT-M1) or NB-

IoT (LTE-CAT-NB1) mobile radio or a plant-side LoRaWAN network. The transmission or evaluation is carried out via an Asset Manage-

ment System, e.g. VEGA Inventory System. Voltage supply The device is supplied with energy by integrated, exchangeable pri-

mary cells. The lithium cell used for this purpose is a compact storage device high cell voltage and capacity for a long service life. Activation Adjustment 3.3 Adjustment The device is activated contactlessly from outside:

pendent position sensor. 4 Mounting 4 Mounting 4.1 General instructions The instrument is suitable for standard and extended ambient condi-

tions acc. to DIN/EN/IEC/ANSI/ISA/UL/CSA 61010-1. It can be used indoors as well as outdoors. 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. Hence make sure before mounting that all parts of the instrument ex-

posed to the process are suitable for the existing process conditions. Note:

If the container is aligned horizontally (e.g. tilted during transport of a mobile container) no measurement is taken. 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 position of the polarisation is in the middle of the type label on the instrument. 1 Fig. 4: Position of the polarisation 1 Middle of the type label Note:

When the device is rotated, the direction of polarization changes and hence the influence of the false echo on the measured value. Please keep this in mind when mounting or making changes later. When mounting the device, keep a distance of at least 200 mm

(7.874 in) from the vessel wall. If the device is installed in the center of dished or round vessel tops, multiple echoes can arise. However, these can be suppressed by an appropriate adjustment (see chapter

" Setup"). If you cannot maintain this distance, you should carry out a false signal suppression during setup. This applies particularly if buildup on Ambient conditions Process conditions Polarisation Installation position 5 1 2 1 0 2

Fig. 8: Recommended socket mounting of VEGAPULS Air 41 If the reflective properties of the medium are good, you can mount VEGAPULS Air 41 on sockets longer than the antenna. The socket end should be smooth and burr-free, if possible also rounded. Note:

When mounting on longer nozzles, we recommend carrying out a false signal suppression (see chapter " Parameter adjustment"). 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. h d Fig. 9: Socket mounting with deviating socket dimensions Socket diameter d Socket length h 80 mm 100 mm 150 mm 3"

wanted access from outside. This means that only authorized persons can receive measured and status values and change device settings via this interface. A Bluetooth access code is required to establish Bluetooth com-

munication via the adjustment tool (smartphone/tablet/notebook). This code must be entered once when Bluetooth communication is established for the first time in the adjustment tool. It is then stored in the adjustment tool and does not have to be entered again. The Bluetooth access code is individual for each device. It is printed on the device housing and is also supplied with the device in the infor-

mation sheet " PINs and Codes". It can be changed by the user after the first connection has been established. If the Bluetooth access code has not been entered correctly, a new entry can only be made after a waiting period has elapsed. The waiting time increases with each additional incorrect entry. The emergency Bluetooth access code enables Bluetooth communi-

cation to be established in the event that the Bluetooth access code is no longer known. It can't be changed. The emergency Bluetooth access code can be found in information sheet " Access protection". If this document is lost, the emergency Bluetooth access code can be retrieved from your personal contact person after legitimation. The storage and transmission of Bluetooth access codes is always encrypted (SHA 256 algorithm). 5.2 Protection of the parameterization The settings (parameters) of the device can be protected against un-

wanted changes. The parameter protection is deactivated on delivery, all settings can be made. To protect the parameterization, the device can be locked by the user with the aid of a freely selectable device code. The settings (param-

eters) can then only be read out, but not changed. The device code is also stored in the adjustment tool. However, unlike the Bluetooth access code, it must be re-entered for each unlock. When using the adjustment app or DTM, the stored device code is then suggested to the user for unlocking. The emergency device code allows unlocking the device in case the device code is no longer known. It can't be changed. The emergency device code can also be found on the supplied information sheet " Ac-

cess protection". If this document is lost, the emergency device code can be retrieved from your personal contact person after legitimation. The storage and transmission of the device codes is always encrypt-

ed (SHA 256 algorithm). 6 4 8 0 8

Deactivated Activated Information:

On delivery, the device is in the deactivated state and must be acti-

vated for operation using a smartphone or magnet. The activation and function of these operating modes is described below. In the deactivated state, the device is not woken up by the integrated clock despite a set measuring interval. The fact that the sensor does not wake up and does not carry out measurement cycles or communication means that the lithium cell is not unnecessarily discharged. In this state, longer storage is possible until the device is used. The following options are available for activating the device from the deactivated delivery status:

By smartphone with VEGA Tools app via NFC Via magnet By smartphone Proceed as follows for activation by NFC:

1. Start VEGA Tools app on smartphone 2. Activate NFC communication 3. Hold the adjustment tool tightly on the instrument side with the lettering " VEGA"

Note:

If no Bluetooth connection is established within these 60 seconds, the device automatically returns to sleep mode. If an established Bluetooth connection is interrupted, a new connection is possible for a further 10 seconds, etc. When activated, the device is woken up by the integrated clock and carries out a measurement cycle (measurement and transmission). It then automatically switches to an energy-saving sleep mode. The measuring interval runs on the basis of the factory pre-configura-

tion or a user-set configuration. Note:

In sleep mode, it is not possible to connect to the device via Bluetooth. The instrument can be deactivated via the VEGA Tools app or the DTM, e.g. for temporary shutdown. The device is reactivated as described above. To transmit the measured values to the cloud, the device requires ac-

cess to mobile network or a LoRaWAN network at the installation site, depending on the version. If no corresponding network is available, a LoRaWAN gateway must be installed. Note:

Ensure free access to the radio network. The device must not be cov-

ered by metal - especially at medium height - or even enclosed. Note:

Simultaneous operation of LTE-M or LTE-IoT and LoRaWAN is not supported. The following measured values are transmitted:

tion occurs Causes of malfunction Fault rectification 10 Diagnostics and servicing 10 Diagnostics and servicing 10.1 Maintenance If the device is used properly, no special maintenance is required in normal operation. In some applications, buildup on the antenna system can influence the measuring result. Depending on the sensor and application, take measures to avoid heavy soiling of the antenna system. If necessary, clean the antenna system in certain intervals. The cleaning helps that the type label and markings on the instrument are visible. Take note of the following:

Use only cleaning agents which do not corrode the housings, type Use only cleaning methods corresponding to the housing protec-

label and seals tion rating 10.2 Rectify faults The operator of the system is responsible for taking suitable meas-

ures to rectify faults. The device offers maximum reliability. Nevertheless, faults can occur during operation. These may be caused by the following, e.g.:

Sensor Process Charge state of the lithium cell Availability/quality of radio transmission Signal processing The first measures are:

Evaluation of fault messages Checking the output signal Checking the radio quality or availability of the radio standard Treatment of measurement errors A smartphone/tablet with the adjustment app or a PC/notebook with the software PACTware and the suitable DTM offer you further com-

prehensive diagnostic possibilities. In many cases, the causes can be determined in this way and the faults eliminated. 5 1 2 1 0 2

fication Depending on the reason for the fault and the measures taken, the steps described in chapter " Setup" must be carried out again or must be checked for plausibility and completeness. 24 hour service hotline Should these measures not be successful, please call in urgent cases the VEGA service hotline under the phone no. +49 1805 858550. The hotline is also available outside normal working hours, seven days a week around the clock. VEGAPULS Air 41 Autarkic device with measured value transmission via radio technology 29 10 Diagnostics and servicing Status messages Since we offer this service worldwide, the support is provided in English. The service itself is free of charge, the only costs involved are the normal call charges. 10.3 Status messages according to NE 107 The instrument features self-monitoring and diagnostics according to NE 107 and VDI/VDE 2650. In addition to the status messages in the following tables there are more detailed error messages available under the menu item " Diagnostics" via the respective adjustment module. The status messages are divided into the following categories:

Failure Function check Out of specification Maintenance required and explained by pictographs:

1 2 3 4 Fig. 19: Pictographs of the status messages 1 Failure - red 2 Out of specification - yellow 3 Function check - orange 4 Maintenance required - blue Failure: Due to a malfunction in the instrument, a fault message is output. This status message is always active. It cannot be deactivated by the user. Function check: The instrument is being worked on, the measured value is temporarily invalid (for example during simulation). This status message is inactive by default. Out of specification: The measured value is unreliable because an instrument specification was exceeded (e.g. electronics temperature). This status message is inactive by default. Maintenance required: Due to external influences, the instrument function is limited. The measurement is affected, but the measured value is still valid. Plan in maintenance for the instrument because a failure is expected in the near future (e.g. due to buildup). This status message is inactive by default. 6 4 8 0 8

Each packet is given an identifier at the begin-

ning which defines the meaning of the following bytes. The byte order corresponds to the Cayenne Low Power Payload (LPP) Guideline as BigEndian. Packet 2 is transferred as standard. Alternative packets are required if additional characteristic val-

ues (error status, position) occur in the sensor. The maximum packet size is 52 bytes in Europe and 11 bytes in the USA with maximum splay factor. A LoRa standard function additionally transmits a packet counter and the serial number of the LoRa module with every packet.

2 0 1 2 1 5 Application area 8 VEGAPULS Air 42 Autarkic device with measured value transmission via radio technology Functional principle 3 Product description The measurement is carried out through a suitable nozzle opening on the vessel. The instrument emits a continuous, frequency-modulated radar signal through its antenna. The emitted signal is reflected by the medium and received by the antenna as an echo with modified frequency. The frequency change is proportional to the distance and is converted into the level. The measured value is transmitted wirelessly as part of the data transmission. The measuring cycle described above is time-controlled via the integrated clock. Outside of the measuring cycle, the device is in a sleep mode. Measured value transmis-

sion Depending on the availability of the radio networks, the device trans-

mits its measured values wirelessly to an LTE-M (LTE-CAT-M1) or NB-

IoT (LTE-CAT-NB1) mobile radio or a plant-side LoRaWAN network. The transmission or evaluation is carried out via an Asset Manage-

ment System, e.g. VEGA Inventory System. Voltage supply The device is supplied with energy by integrated, exchangeable pri-

mary cells. The lithium cell used for this purpose is a compact storage device high cell voltage and capacity for a long service life. Activation Adjustment 3.3 Adjustment The device is activated contactlessly from outside:

pendent position sensor. 4 Mounting 4 Mounting 4.1 General instructions The instrument is suitable for standard and extended ambient condi-

tions acc. to DIN/EN/IEC/ANSI/ISA/UL/CSA 61010-1. It can be used indoors as well as outdoors. 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. Hence make sure before mounting that all parts of the instrument ex-

posed to the process are suitable for the existing process conditions. Note:

If the container is aligned horizontally (e.g. tilted during transport of a mobile container) no measurement is taken. 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 position of the polarisation is in the middle of the type label on the instrument. 1 Fig. 4: Position of the polarisation 1 Middle of the type label Note:

When the device is rotated, the direction of polarization changes and hence the influence of the false echo on the measured value. Please keep this in mind when mounting or making changes later. When mounting the device, keep a distance of at least 200 mm

(7.874 in) from the vessel wall. If the device is installed in the center of dished or round vessel tops, multiple echoes can arise. However, these can be suppressed by an appropriate adjustment (see chapter

" Setup"). Ambient conditions Process conditions Polarisation Installation position 5 1 2 1 0 2

Fig. 8: Recommended socket mounting of VEGAPULS Air 42 If the reflective properties of the medium are good, you can mount VEGAPULS Air 42 on sockets longer than the antenna. The socket end should be smooth and burr-free, if possible also rounded. Note:

When mounting on longer nozzles, we recommend carrying out a false signal suppression (see chapter " Parameter adjustment"). 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. h d Fig. 9: Socket mounting with deviating socket dimensions Socket diameter d Socket length h 80 mm 100 mm 150 mm 3"

wanted access from outside. This means that only authorized persons can receive measured and status values and change device settings via this interface. A Bluetooth access code is required to establish Bluetooth com-

munication via the adjustment tool (smartphone/tablet/notebook). This code must be entered once when Bluetooth communication is established for the first time in the adjustment tool. It is then stored in the adjustment tool and does not have to be entered again. The Bluetooth access code is individual for each device. It is printed on the device housing and is also supplied with the device in the infor-

mation sheet " PINs and Codes". It can be changed by the user after the first connection has been established. If the Bluetooth access code has not been entered correctly, a new entry can only be made after a waiting period has elapsed. The waiting time increases with each additional incorrect entry. The emergency Bluetooth access code enables Bluetooth communi-

cation to be established in the event that the Bluetooth access code is no longer known. It can't be changed. The emergency Bluetooth access code can be found in information sheet " Access protection". If this document is lost, the emergency Bluetooth access code can be retrieved from your personal contact person after legitimation. The storage and transmission of Bluetooth access codes is always encrypted (SHA 256 algorithm). 5.2 Protection of the parameterization The settings (parameters) of the device can be protected against un-

wanted changes. The parameter protection is deactivated on delivery, all settings can be made. To protect the parameterization, the device can be locked by the user with the aid of a freely selectable device code. The settings (param-

eters) can then only be read out, but not changed. The device code is also stored in the adjustment tool. However, unlike the Bluetooth access code, it must be re-entered for each unlock. When using the adjustment app or DTM, the stored device code is then suggested to the user for unlocking. The emergency device code allows unlocking the device in case the device code is no longer known. It can't be changed. The emergency device code can also be found on the supplied information sheet " Ac-

cess protection". If this document is lost, the emergency device code can be retrieved from your personal contact person after legitimation. The storage and transmission of the device codes is always encrypt-

ed (SHA 256 algorithm). 6 4 5 7 9

Deactivated Activated Information:

On delivery, the device is in the deactivated state and must be acti-

vated for operation using a smartphone or magnet. The activation and function of these operating modes is described below. In the deactivated state, the device is not woken up by the integrated clock despite a set measuring interval. The fact that the sensor does not wake up and does not carry out measurement cycles or communication means that the lithium cell is not unnecessarily discharged. In this state, longer storage is possible until the device is used. The following options are available for activating the device from the deactivated delivery status:

By NFC technology via smartphone with VEGA Tools app Via magnet By NFC technology Proceed as follows for activation by NFC:

1. Start VEGA Tools app on smartphone 2. Activate NFC communication 3. Hold the adjustment tool tightly on the instrument side with the lettering " VEGA"

Note:

The NFC antenna of the adjustment tool should be located directly on the VEGA lettering. If the position of the antenna is unknown, it is advisable to change the position of the adjustment tool. 2 1 6 4 5 7 9

If no Bluetooth connection is established within these 60 seconds, the device automatically returns to sleep mode. If an established Bluetooth connection is interrupted, a new connection is possible for a further 10 seconds, etc. When activated, the device is woken up by the integrated clock and carries out a measurement cycle (measurement and transmission). It then automatically switches to an energy-saving sleep mode. The measuring interval runs on the basis of the factory pre-configura-

tion or a user-set configuration. Note:

In sleep mode, it is not possible to connect to the device via Bluetooth. The instrument can be deactivated via the VEGA Tools app or the DTM, e.g. for temporary shutdown. The device is reactivated as described above. To transmit the measured values to the cloud, the device requires ac-

cess to mobile network or a LoRaWAN network at the installation site, depending on the version. If no corresponding network is available, a LoRaWAN gateway must be installed. Note:

Ensure free access to the radio network. The device must not be cov-

ered by metal - especially at medium height - or even enclosed. Activated Deactivate Communication 5 1 2 1 0 2

tion occurs Causes of malfunction Fault rectification 10 Diagnostics and servicing 10 Diagnostics and servicing 10.1 Maintenance If the device is used properly, no special maintenance is required in normal operation. In some applications, buildup on the antenna system can influence the measuring result. Depending on the sensor and application, take measures to avoid heavy soiling of the antenna system. If necessary, clean the antenna system in certain intervals. The cleaning helps that the type label and markings on the instrument are visible. Take note of the following:

Use only cleaning agents which do not corrode the housings, type Use only cleaning methods corresponding to the housing protec-

label and seals tion rating 10.2 Rectify faults The operator of the system is responsible for taking suitable meas-

ures to rectify faults. The device offers maximum reliability. Nevertheless, faults can occur during operation. These may be caused by the following, e.g.:

Sensor Process Charge state of the lithium cell Availability/quality of radio transmission Signal processing The first measures are:

Evaluation of fault messages Checking the output signal Checking the radio quality or availability of the radio standard Treatment of measurement errors A smartphone/tablet with the adjustment app or a PC/notebook with the software PACTware and the suitable DTM offer you further com-

prehensive diagnostic possibilities. In many cases, the causes can be determined in this way and the faults eliminated. 5 1 2 1 0 2

The service itself is free of charge, the only costs involved are the normal call charges. 10.3 Status messages according to NE 107 The instrument features self-monitoring and diagnostics according to NE 107 and VDI/VDE 2650. In addition to the status messages in the following tables there are more detailed error messages available under the menu item " Diagnostics" via the respective adjustment module. The status messages are divided into the following categories:

Failure Function check Out of specification Maintenance required and explained by pictographs:

1 2 3 4 Fig. 19: Pictographs of the status messages 1 Failure - red 2 Out of specification - yellow 3 Function check - orange 4 Maintenance required - blue Failure: Due to a malfunction in the instrument, a fault message is output. This status message is always active. It cannot be deactivated by the user. Function check: The instrument is being worked on, the measured value is temporarily invalid (for example during simulation). This status message is inactive by default. Out of specification: The measured value is unreliable because an instrument specification was exceeded (e.g. electronics temperature). This status message is inactive by default. Maintenance required: Due to external influences, the instrument function is limited. The measurement is affected, but the measured value is still valid. Plan in maintenance for the instrument because a failure is expected in the near future (e.g. due to buildup). This status message is inactive by default. 6 4 5 7 9

In the following, the necessary device-specific details are shown. You can find further information of LoRaWAN on www.lora-alliance.org. Data stream, byte order, packet structure The data are transferred as a byte stream in packets. Each packet is given an identifier at the begin-

ning which defines the meaning of the following bytes. The byte order corresponds to the Cayenne Low Power Payload (LPP) Guideline as BigEndian. Packet 2 is transferred as standard. Alternative packets are required if additional characteristic val-

ues (error status, position) occur in the sensor. The maximum packet size is 52 bytes in Europe and 11 bytes in the USA with maximum splay factor. A LoRa standard function additionally transmits a packet counter and the serial number of the LoRa module with every packet.
