3.2 Principle of operation
VEGAMET 391 is a universal signal conditioning instrument for a
variety 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 VEGA Inventory System. It
is also possible to send measured values and messages via e-mail/
SMS.The use of VEGAMET 391 is particularly suitable for stocktak-
ing, VMI (Vendor Managed Inventory) and remote enquiry.
The VEGAMET 391 signal conditioning instrument can power the
connected sensor and process its measurement signals. The re-
quested 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 display or a superordinate
control system. Operating relays for control of pumps or other devices
are also integrated.
Wide range power supply unit with 20 … 253 V AC/DC for worldwide
use.
Detailed information about the power supply can be found in chapter
"Technical data".
3.3 Adjustment
The instrument can be adjusted with the following adjustment media:
• With integrated display and adjustment unit
• an adjustment software according to FDT/DTM standard, e.g.

4.1 General instructions
The instrument is designed for recessed installation in an instrument
panel, housing front plate or switching cabinet door. The required
cut-out is 92 x 92 mm (3.63 x 3.63 in) according to EN 60529. When
installed correctly, protection rating IP 65 is guaranteed. As an alter-
native, the instrument can be mounted in a switching cabinet or pro-
tective housing by means of four screws (attached with screws to rear
of housing). A mounting adapter for carrier rail mounting is available
as an option (top hat rail 35 x 7.5 according to DIN EN 50022/60715).
Note:
If the instrument is mounted via screws or carrier rail, it must always
be inside a switching cabinet or protective case.
A VEGAMET 391 in Ex version is an auxiliary, intrinsically safe instru-
ment and may not be installed in explosion-endangered areas.
Before setup, the Ex separating wall must be attached to Ex versions.
Safe operation can only be ensured if the operating instructions
manualandtheECtypeapprovalcerticateareobserved.VEGAMET
391 must not be opened.
The instrument is suitable for standard ambient conditions acc. to
DIN/EN/IEC/ANSI/ISA/UL/CSA 61010-1.

5 Connecting to power supply
5.1 Preparing the connection
Always keep in mind the following safety instructions:
Warning:
Connect only in the complete absence of line voltage.
• Connect only in the complete absence of line voltage
• If overvoltage surges are expected, overvoltage arresters should
be installed
Note:
Install a separating facility for the instrument which is easy to access.
The separating facility must be marked for the instrument (IEC/
EN 61010).
In hazardous areas you must take note of the respective regulations,
conformityandtypeapprovalcerticatesofthesensorsandpower
supply units.
The voltage supply can be 20 … 253 V AC/DC, 50/60 Hz.
The voltage supply of VEGAMET 391 is connected with standard
cable according to the national installation standards.
Standard two-wire cable can be used for connecting the sensors. The
screening is absolutely necessary to ensure interference-free opera-
tion with HART sensors.
Make sure that the cable used has the required temperature resist-
anceandresafetyformax.occurringambienttemperature
Connect the cable screen on both ends to ground potential. In the
sensor, the screen must be connected directly to the internal ground
terminal.The ground terminal on the outside of the sensor housing
must be connected to the potential equalisation (low impedance).
If potential equalisation currents are expected, the screen connection
on the side of VEGAMET 391 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eectagainsthighfrequency
interference signals remains.
Take note of the corresponding installation regulations for Ex applica-
tions. In particular, make sure that no potential equalisation currents
owoverthecablescreen.Incaseofgroundingonbothsidesthis
can be achieved by the use of a capacitor or a separate potential
equalisation.
5.2 Input mode active/passive
Through the selection of the terminals, you can choose between ac-
tive and passive operation of the measuring data intput.
• In active mode, VEGAMET 391 provides the power for the con-
nected sensors. Power and measurement data are transmitted

over the same two-wire cable.This mode is provided for connec-
tion of measuring transducers without separate power supply
(sensors in two-wire version).
• In passive mode the sensors are not powered, only the measured
value is transmitted.This input is for connection of transmitters
with their own separate voltage supply (sensors in four-wire ver-
sion).The VEGAMET 391 can also be looped into the existing
circuit like a normal ammeter.
Note:
With a VEGAMET 391 in Ex version, the passive input is not available
for approval technical reasons.

Approx. 10 minutes after the last pressing of a key, an automatic reset
tomeasuredvalueindicationistriggered.Anyvaluesnotconrmed
with [OK] will not be saved.
6.2 Setup steps
Through parameter adjustment, the instrument is adapted to the indi-
vidual application conditions. A measurement loop calibration is the
most important step and should always be carried out. A scaling of
the measured value to the desired physical variable and unit, possibly
including a linearisation curve, is often useful.The adaptation of the
relay switching points or the setting of an integration time to smooth
the measured value are further standard adjustment options.
Instruments with Ethernet interface can be provided with a Host name
suitable for the measurement loop. As an alternative to the addressing
via DHCP, it is also possible to adjust an IP address and subnet mask
suitable for your network. If necessary, the e-mail/Web server can be
alsoconguredwithPACTware.
A setup assistant is available for easy, convenient setup. It guides the
user through the standard applications and settings step by step.
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 display and adjustment unit. Communication is carried
out via the integrated USB interface or one of the optional interfaces
(RS232/Ethernet).
Further instructions for setting up the web server and e-mail functions
are stated in the online help of PACTware or the VEGAMET 391 DTMs
aswellasthesupplementaryinstructionsmanual"RS232/Ethernet
connection".

measurement loop name (measurement loop TAG) and the unit. An
analoguebargraphcanalsobedisplayed.Ifowmeasurementwith

becomes available. If pump control is activated, an additional window
for indication of the assigned pumps is available. By pushing the [>]

→ By pressing [OK], you move from measured value indication
to the main menu. Here you can choose between the setup as-
sistant for the most important settings and the complete classic
menu.
At the beginning of every setup or parameter adjustment, you have
the choice of continuing with the setup assistant or the classic menu
guidance.We recommend using the setup assistant for the initial
setup. If individual settings need to be corrected or added later, the
most expedient way to do this is to use the classic menus.
→ Selectthemenuitem"Setup assistant"with[->]andconrmwith
[OK].
The setup assistant leads you step-by-step through the standard set-
tings.The following steps are carried out:
• Device-TAG (individually adjustable instrument name)
• Measurement loop TAG (individually adjustable measurement loop
designation)
• Type of input (4 … 20 mA or HART)
• Measured variable (for example level or process pressure)
• Adjustment unit (for example m or bar)
• Min./Max. adjustment
• Activation of the fail safe relay
• Congurationoftherelayoutputs(e.g.setupofpumpcontrolor
overllprotection)
• Setting Date/Time with option RS232/Ethernet interface
• Networksettingswithoption"Ethernetinterface"
When changing the measurement, the assistant can be called up any
time.The subsequent steps can also be reached individually via the
traditional menu navigation. A description of the individual menu items
isavailableinthetraditionalmenus.Inchapter"Application examples"
youwillndfurtherinformationaboutsetup.
The main menu is divided into six areas with the following functions:
• Device settings: Includes the device-TAG, settings for network
connection such as date/time setting, …
• Measurement loop: Includes settings for input selection, adjust-
ment, damping, linearisation, scaling, outputs, …
• Display: Includes settings for the displayed measured value,
language and brightness of the background lighting
• Diagnosis Includes information on device status, error messages,
input current, digital inputs
