2.8Overfill protection according to WHG
InGermany 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
protection.The VEGAMET 391 fulfils the construction and testing
principles for overfill protection systems.This is certified by the TÜV
(Technical Control Board)statement "PP 5003/09".You can download
this document from our homepage under "Downloads -Approvals -
Signal conditioning instruments -Overfill protection".
2.9Environmental instructions
Protection of the environment is one of our most important duties.That
is why we have introduced an environment management system with
the goal of continuously improving company environmental protection.
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:

The serial number allows you to access the delivery data of the
instrument via www.vega.com,"VEGA Tools"and "serial number
search".
3.2Principle of operation
VEGAMET 391 is a universal signal conditioning instrument for a
number of applications such as level,gauge and process pressure
measurement.At the same time,it can serve as power supply unit for
connected sensors.VEGAMET 391 is designed for connection of any
4…20 mA/HART sensor.
On instruments with one of the optional interfaces (RS232/Ethernet),
the measured values can be retrieved via modem or network and
displayed by means of a web browser or WEB-VV.It is also possible to
send measured values and messages via e-mail/SMS.The use of
VEGAMET 391 is particularly suitable for stocktaking,VMI (Vendor
Managed Inventory)and remote enquiry.
The VEGAMET 391 signal conditioning instrument can power the
connected sensor and process its measurement signals.The
requested parameter is shown on the display and also outputted to the
integrated current output for further processing.The measurement
signal can thus be transferred to a remote indication or a superordinate
control system.Six level relays for control of pumps or other devices
are also integrated.
Wide-range power supply unit with 20 …253 V AC/DC for world-wide
use.
Detailed information about the power supply can be found in chapter
"Technical data".
3.3Operation
The instrument can be adjusted with the following adjustment media:
lWith integrated indicating and adjustment unit
lan adjustment software according to FDT/DTM standard,e.g.
PACTware and a Windows PC
The entered parameters are generally saved in VEGAMET 391,when
used with PACTware and PC optionally also on the PC.
Information:
When using PACTware and the respective DTM,additional settings
can be carried out which are not possible or only partly possible with
the integrated indicating and adjustment unit.Communication is
carried out via the integrated USB interface or one of the optional
interfaces (RS232/Ethernet).

4Mounting
4.1General instructions
The instrument is designed for recessed installation in a front panel,
housing front plate or a switching cabinet door.The required cut-out is
92 x92 mm according to EN 60529.When installed correctly,
protection rating IP 65 is guaranteed.As an alternative,the instrument
can be mounted into a switching cabinet or housing by means of four
screws (fixed with screws on rear of housing).
A VEGAMET 391 in Ex version is an auxiliary,intrinsically safe
instrument and may not be installed in explosion-endangered areas.
Before setup,the Ex separating wall must be attached with Ex
versions.Safe operation can be only ensured if the operating
instructions manual and the EG type approval certificate are observed.
VEGAMET 391 must not be opened.
4.2Mounting instructions
1Check the correct hold of the seal directly behind the front plate
and shift the instrument from the front into the front panel cut-out.
2Shift the two tensioning elements into the provided gaps.
3Screw in the two screws of the tensioning elements steadily with a
screwdriver.
