of successful testing.You can ﬁnd the CE conformity declaration in the

download area of www.vega.com.

2.7Safety instructions for Ex areas

Please note the Ex-speciﬁc safety information for installation and

operation in Ex areas.These safety instructions are part of the

operating instructions manual and come with the Ex-approved

instruments.

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:

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.
