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. For special versions, PE foam or PE foil is also used.
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 The position of the polarisation is in the middle of the type label on the instrument. 1 Fig. 5: Position of the polarisation 1 Installation position Middle of the type label When mounting the sensor, keep a distance of at least 200 mm (7.874 in) from the vessel wall. If the sensor 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").
4 Mounting Reference plane The antenna edge of the device is the beginning of the measuring range and at the same time the reference plane for the min./max. adjustment, see following diagram: 1 Fig. 8: Reference plane 1 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.

Vessel installations, such as e.g.
4 Mounting 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. 14: Agitators Foam generation Through the action of filling, stirring and other processes in the vessel, compact foams which considerably damp the emitted signals may form on the product surface.

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 5.3 Switch-on phase After connection to the power supply, the device carries out a selftest: • • Internal check of the electronics Output signal is set to failure The current measured value is then output on the signal cable.
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 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. The storage and transmission of the device codes is always encrypted (SHA 256 algorithm).
7 Setup with smartphone/tablet (Bluetooth) 7 System requirements Setup with smartphone/tablet (Bluetooth) 7.1 Preparations Make sure that your smartphone/tablet meets the following system requirements: • • • Operating system: iOS 8 or newer Operating system: Android 4.3 or newer Bluetooth 4.0 LE or newer Download the VEGA Tools app from the "Apple App Store", "Google Play Store" or "Baidu Store" to your smartphone or tablet. 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.

10 Diagnostics and servicing 10 Diagnostics and servicing Maintenance 10.1 Maintenance If the device is used properly, no special maintenance is required in normal operation. Precaution measures against buildup 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.
10 Diagnostics and servicing 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. 4 … 20 mA signal 10.3 Diagnosis, fault messages Connect a multimeter in the suitable measuring range according to the wiring plan.
10 Diagnostics and servicing 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: Due to external influences, the instrument function is limited.
