Product description 3 Product description 3.
Product description 3.2 Principle of operation Area of application VEGAMET 625 is a universal signal conditioning instrument for a number of applications such as level, gauge, interface and process pressure measurement. At the same time, it can serve as power supply unit for connected sensors. VEGAMET 625 is designed for connection of two independent VEGA HART sensors. Hence two independent measurements can be carried out.
Product description and adjustment unit. If an adjustment software is used, you either need one of the integrated interfaces (RS232/Ethernet) or the interface converter VEGACONNECT. Further instructions for setting up the web server and e-mail functions are stated in the online help of PACTware™ or the VEGAMET 625 DTM as well as the operating instructions manual "RS232/Ethernet connection". 3.4 Storage and transport Packaging Your instrument was protected by packaging during transport.
Mounting 4 Mounting 4.1 General instructions Installation location Each series 600 instrument consists of the actual signal conditioning instrument as well as a plug-in socket for carrier rail mounting. Because it has protection class IP 30 or IP 20, the instrument is intended to be used in switching cabinets. 4.2 Mounting information Mounting The plug-in socket is constructed for carrier rail mounting acc. to EN 50022. Power supply is connected to terminals 17 and 18.

Connecting to power supply 5 Connecting to power supply 5.1 Preparing the connection Note safety instructions Always observe the following safety instructions: l l Connect only in the complete absence of line voltage If overvoltages are expected, overvoltage arresters should be installed. Tip: We recommend VEGA overvoltage arresters B61-300 (power supply VEGAMET 625) and B62-36G (sensor supply).
Connecting to power supply 5.2 Connection procedure Tip: Before the actual setup, each HART sensors must be assigned an address (see chapter "Setup"). When assigning an address, only one sensor should be connected to VEGAMET 625. Depending on the installation location of the sensors, it can be advantageous to carry out this addressing before installing and connecting the sensors. This can be conveniently carried out e.g. in the workshop.
Connecting to power supply separate power supply (sensors in four-wire version). The connection and operation in Ex ia is not permitted on the passive input. Note: VEGAMET 625 is designed for connection of two HART sensors. Because they are accessed via different addresses in the HART multidrop mode, both sensors are connected to the same sensor input. These are either terminals 1/2 (active input) or terminals 3/4 (passive input). Simultaneous mixed operation on active and passive input is not possible.

Setup with the integrated indicating and adjustment unit 6 Setup with the integrated indicating and adjustment unit 6.1 Adjustment system Function The integrated indicating and adjustment unit is used for measured value display, adjustment and diagnosis of VEGAMET 625 as well as the connected sensors. Indication and adjustment are made via four keys and a clear, graphiccapable indication with background lighting. The adjustment menu with language selection is clearly structured and enables easy setup.
Setup with the integrated indicating and adjustment unit l l - editing position [+] key: - modify value of a parameter [ESC] key: - interrupt input - jump to the next higher menu Note: Approx. 10 minutes after the last pressing of a key, an automatic reset to measured value indication is triggered. Any values not confirmed with [OK] will not be saved. 6.2 Setup procedure Set up Setup encompasses mainly the selection of the application and the adjustment of the measurement loop.
Setup with the integrated indicating and adjustment unit l l l Internal check of the electronics indication of the instrument type, firmware version as well as the instrument TAG (instrument name) the output signals jump briefly to the set fault current Then the current measured values will be displayed and outputted. Measured value indication/ Main menu As requested, the measured value display shows the individual measurement loops separately or in a joint overview.
Setup with the integrated indicating and adjustment unit Application ▶ Standard Interface à Select the requested application with [–>] and save your settings with [OK]. Then move to the menu item Input with "[–>]". Device settings – Input Because VEGAMET 625 has two inputs, the measurement loops must be assigned to the inputs. After the addresses of the HART sensors are assigned, a list with the existing sensors can be prepared and displayed via "Sensor selection – Sensor search".
Setup with the integrated indicating and adjustment unit Device-TAG Device Name à Enter the requested values via the appropriate keys and save your settings with [OK]. Device settings – Host Name/ IP address For instruments with integrated Ethernet interface also a host name and the IP address must Subnet Mask for integration in the network must be entered. These specifications are available from your network administrator. These settings are only effective after a restart of VEGAMET 625.

Setup with the integrated indicating and adjustment unit Note: When addresses are being assigned, only one sensor with a particular address must be connected on the bus. If this is not the case, the sensor cannot be accessed and it is not possible to assign an address. Set the current HART address of the requested sensor in the menu item "Previous address". The default setting of all supplied VEGA sensors is always 00.

Application examples 8 Application examples 8.1 Interface measurement with VEGAFLEX 67 In an interface measurement, there are two different media which do not mix, e.g. water and oil or solvents. To detect the volume of both products, it is necessary to detect the height of the upper liquid (level) and the interface between the two products. A VEGAFLEX 67 is necessary as a transmitter which delivers the distance to the upper medium as well as the distance to the interface.
Application examples 1 d2 d1 L2 h2 TS L1 h1 Fig. 1 d1 d2 TS h1 h2 L1 L2 10: Interface measurement Reference plane Distance to the interface, meas. loop 1 Distance to the level, meas. loop 2 Thickness of the upper medium (d1-d2), meas. loop 3 (displayed value) Height - Interface (displayed value) Height - Level (displayed value) Lower medium Upper medium 8.2 Flow measurement Physical principle For flow measurement in open flumes, a contraction or standardised flume must be used.
Application examples l l l Select flume (Linearization) Set scaling Parameter adjustment of pulse outputs Parameter – Flow Select in the DTM window "Parameter" the option "Flow" with the requested unit of measurement. Adjustment Min. adjustment: Enter the suitable value for 0 %, i.e. the distance from the sensor to the medium as long as there is no flow. These are in the following example 1.40 m. Max. adjustment: Enter the suitable value for 100 %, i.e.
Application examples In mode "Sampling pulse" an additional pulse is outputted after a defined time. This means that a timer is started after each pulse after which another pulse is outputted. This applies only if already a pulse was outputted after exceeding the flow volume. 28970-EN-050616 Due to sludge at the bottom of the flume, it can happen that the min. adjustment originally carried out can no longer be reached.
Maintenance and fault rectification 9 Maintenance and fault rectification 9.1 Maintenance When used as directed in normal operation, VEGAMET 625 is completely maintenance-free. 9.2 Fault rectification Causes of malfunction VEGAMET 625 offers maximum reliability. Nevertheless faults can occur during operation. These may be caused by the following, e.g.
