• Page 5: For Your Safety

  During work on and with the device the required personal protective equipment must always be worn. Appropriate use VEGAMET 625 is a universal signal conditioning instrument and power supply unit for connection of two HART sensors. You can find detailed information about the area of application in chapter «Product description».

• Page 6: Safety Label On The Instrument

  Ex-approved instruments. 2.9 Overfill protection according to WHG In Germany the WHG (Water Resource Act) stipulates an overfill protection for systems that deal with substances hazardous to water. An appropriately certified sensor is the prerequisite for such protec- tion. The VEGAMET 625 fulfils the construction and testing principles for overfill protection systems. This is certified by the TÜV (Techni- cal Control Board) statement «PP 5003/09». You can download this document from our homepage under «Downloads — Approvals — Signal conditioning instruments — Overfill protection». VEGAMET 625 • Double channel HART…

• Page 7: Environmental Instructions

  That is why we have introduced an environment management system with the goal of continuously improving company environmental pro- tection. The environment management system is certified according to DIN EN ISO 14001. Please help us fulfil this obligation by observing the environmental instructions in this manual: • Chapter «Packaging, transport and storage» • Chapter «Disposal» VEGAMET 625 • Double channel HART…

  If this rule is not heeded, there is a danger of coming into contact with the operating voltage or causing a short circuit. A VEGAMET 625 in Ex version is an auxiliary, intrinsically safe instru- ment and may not be installed in explosion-endangered areas.

  (low impedance). If potential equalisation currents are expected, the screen connection on the side of VEGAMET 625 must be made via a ceramic capacitor (e. g. 1 nF, 1500 V). The low frequency potential equalisation currents are thus suppressed, but the protective effect against high frequency interference signals remains.

• Page 14: Connection Procedure

  The VEGAMET 625 can also be looped into the existing circuit like a normal ammeter. Note: With a VEGAMET 625 in Ex version, the passive input is not available for approval technical reasons. Connection procedure VEGAMET 625 is designed for connection of two HART sensors.

Insert VEGAMET 625 into the plug-in socket and screw it down tightly Note: If the addressing of the sensors has not yet been carried out, only one sensor must be connected. Addressing (see chapter «Setup») of the first sensor can then be carried out. Afterwards, the first sensor must be disconnected again and the next sensor connected and provided with an address.

  In mode HART Multidrop, an address from 1 … 15 is assigned to the sensor. By doing so, the current is fix limited to 4 mA and the meas- ured value transmission is only made digitally. Each sensor connected to VEGAMET 625 must operate in mode HART multidrop and must be provided with different addresses in the range between 01 … 15. Via the menu item «Sensor address», it is possible to change the address of the connected sensor. For this purpose, enter the previous address of the sensor (factory setting 0) and in the next window the new address.

  Then the instrument can be reached from everywhere in the network via its IP address or Host name. These specifications must also be entered in the DTM (see chapter «Parameter adjustment with PACTware»). If the encrypted DTM remote access is activated in the signal conditioning instrument, the instrument key (PSK) must be entered during the first connection.

  This only applies if a pulse was not already outputted after the flow volume was exceeded. Due to sludge at the bottom of the flume, it can happen that the min. level value originally set can no longer be reached. The result is that small flow quantities will be continuously detected despite the «emp- ty» flume. The option «Min. flow volume suppression» offers the option of suppressing measured flow volumes below a certain percentage value for flow volume detection. VEGAMET 625 • Double channel HART…
