CONTENTS INTRODUCTION
The 600T series is a modular range of field mounted, micro-
processor based electronic transmitters, using a unique
inductive sensing element. Accurate and reliable
measurement of differential pressure, gauge and absolute
pressure, flow and liquid level is provided, in the even most
difficult and hazardous industrial environments.
The 600T Smart series transmitter now includes an Analog
Version (4-20 mA analog output), an Analog Version plus
HART digital communication and a Profibus DP-PA Version.
Digital communication protocols, HART and Profibus, allow
remote re-ranging, calibration and diagnostics.
WithrespecttoHART,thebidirectionaldigitalcommunication
does not have any interference with the standard 4-20 mA
analog output signal.
Profibus has a complete digital only communication.
This manual describes the features, the installation and
calibrationprocedures related tothe 600TSeries Transmitter
with HART Communication Protocol.

the transmitter can be found in the following documents:

PRODUCT IDENTIFICATION
The instrument is identified by the data plates shown in
Figure 1.
The Nameplate (ref.A) provides information concerning the
code number, maximum working pressure, range and span
limits,power supplyandoutputsignal. Seecode/specification
sheet for detailed information. This plate also shows the
transmitterserialnumber. Pleasereferto this number when
making enquiries.
Adedicated label (ref.B) is weldedas standardtothe primary
unit, carrying specific details of the transducer (diaphragms
material, fill fluid, range limit and identification number).
A Safety Marking plate ( ref. C) is fitted when the transmitter
is required to comply with hazardous area regulations, e.g.
flameprooforintrinsicsafety protection.AdditionallyTagplate

PRINCIPLE OF OPERATION
Theprincipleofoperationofthe PrimaryUnitis asfollows.The
process fluid ( liquid, gas or vapour ) exerts pressure on to the
sensor diaphragm via flexible, corrosion-resistant isolating
diaphragms and capillary tubing containing the fill fluid (see
Fig. 2a).
As the sensor diaphragm deflects in response to differential
pressurechanges,itsimultaneouslyproducesvariationsinthe
gap between two fixed magnetic circuits (comprising coil and
ferrite core) positioned on both sides of the measuring
diaphragm. As a result, the inductance of each coil changes.
The two inductance values L1 and L2, and the sensor
temperature ST are combined in the primary electronics to
provide a proprietary standardized signal.

With secondary electronics analog and analog+HART, it is to
be consider that different communication protocols exist for
configuration and maintenance operations. Here follows a
brief description on the matter; please refer to appropriate
technical specification for additional deeper explanations on
the communication aspects.
The HART protocol is based on the standard Bell 202 FSK
(Frequency Shift Keying ) with a ±0.5 mA signal modulation
superimposed on the 4 to 20 mA analog signal. As the energy
balance added to the current loop is virtually zero and the
frequencyisveryhighcomparedtothatoftheprocessdynamic,
the analog process signal remains undisturbed. Using a
configuration device it is then possible to remotely modify the
configuration of the transmitter, e.g. the measuring range.

INSTALLATION

Fig. 6 - Mounting on 2" horizontal pipe
CAUTION - Proper location of the transmitter
with respect to the process pipe will depend upon the
serviceforwhichtheinstrumentisused.Careshouldbe
exercised to identify correct process connections.
The secondary unit of the transmitter may be rotated through
360°approx. with respect to the primary unit without
degrading performance or damaging the internal wiring. Do
not force the primary unit to rotate; use the 2 mm Allen key
supplied to unlock and lock the tang grub screw (see Fig. 7).
This feature, obtained by unscrewing (one turn is sufficient)
the Allen screw, is particularly useful for reaching optimum
accesstotheelectricalconnectionsandvisibilityoftheoutput

WARNING
In order to ensure operator safety and plant safety
it is essential that installation is carried out by
suitablytrainedpersonnelaccordingtothetechni-
cal data provided in the specification for the
relevant model.
The transmitter may bemountedonaverticalorhorizontal 2-
inch pipe (figg. 5 and 6) by means of the same mounting
bracket.
Note: for other installation details see the relevant
Addendum.

WARNING - For installation in Hazardous Areas,
i.e.areaswith dangerousconcentrationsofe.g.gasesor
dusts that may explode if ignited, the installation must be
carried out in accordance with relative standards either
EN 60079-14 or IEC 79-14 and/or with local authority
regulations, for the relevant type of protection adopted.
Togetherwith safetyinformation here andafter enclosed
see also the Addendum for "Ex Safety" aspects which is
part of this instruction manual.
WARNING: The transmitter when installed in
accordance with this instruction manual will not be
subjected to mechanical stresses.
WARNING:thetransmitter shouldnot beinstalled
where it may be subjected to mechanical and thermal
stresses or where it may be attached by existing or
foreseable aggressive substances.

WARNING - For installation in Hazardous Areas,
i.e. areas with danger of fire and/or explosion, prior to
making electrical connections, ensure compliance with
safetyinformationontheSafetyMarkingplate.Failureto
comply with this warning can result in fire or explosion.
Signal terminals are located in a separate compartment of the
secondary unit housing. The housing incorporates two con-
nection ports for cable glands or conduit fittings. They are
protected with a temporary plastic plug for transit purpose
whichshouldbereplacedwithasuitablepermanentpluginthe
unusedport. Connectionscanbemadebyremovingthecover
(indicatedinFig.7);firstscrewdown thelocking screwlocated
below the cover, using a 3 mm Allen Key.
WARNING - For Hazardous Areas installations,the
connectionofcablesandconduitstothetransmittershall
be made in accordance with the requirements of the
relevant type of protection. Cables and cable-glands
must be in accordance with the type of protection.
Unused openings for connection shall be closed with
blanking elements suitable for the relevant type of
protection. With the exception of intrinsically safe
transmitters, the means provided for this shall be such
that the blanking element can be removed only with the
aid of tools. The blanking elements must be certified for
thetypeofprotection.SeestandardseitherEN60079-14
or IEC 79-14. The transmitter connections must also
guarantee the degree of protection of the transmitter
enclosure,e.g. IPxxaccordingto EN60529standard (or
IEC529).SeealsotheAddendumfor"IP"protection(and
Ex Safety) which is part of this instruction manual.
Thesignalcableshouldbeconnectedtotheterminalsmarked
respectively (+) and (-). If an internal output meter - either with
analog or digital indication - is installed, it should be removed
inordertomaketheconnection,simplybypullingitout fromits
socket. After the connections have been made, reinstall the
output meter. Refer to the Meters Option addendum for
details.

ELECTRICAL CONNECTIONS
The power to the transmitter is supplied over the signal wiring
and noadditionalwiringis required.Thesignalwiringdoesnot
need to be shielded but the use of a twisted pair is highly
recommended. The cable shield should be grounded in one
side only, to avoid dangerous earth paths.
WARNING - For Hazardous Areas installations,
whentheambient temperatureishigher than70°C,the
cableusedfortheconnectionsmustbesuitablefor5°C
above the ambient temperature.
Normal practice is to ground in the control room side, in which
case the field side of the screen should be adequately
protected to avoid contact with metallic objects. Signal wiring
may be ungrounded (floating) or grounded at any place in the
signalloop,butforintrinsicallysafeinstallationsthewiringand
groundingmustfollowthespecificrulesforthistechnique. The
transmitter case may be grounded or ungrounded: a ground
connectionisprovidedinternally(intheterminal compartment)
and externally.
Do not run the signal wiring in close proximity to power cable
or high power equipment; use dedicated conduits or trays for
signal wiring.
CAUTION - Do not connect the powered signal
wiring to the mA signal testing terminals as this could
damage the by-pass diode.
Aftertheconnectionshavebeencompletedchecktheintegrity
of the cover O-ring, screw down the cover and secure it by
unscrewing the safety screw.
CAUTION - Unless absolutely necessary, avoid
theremoval onsite oftheprotective coverwhich gives
accesstotheelectroniccircuitry.Although theelectro-
nicsare fullytropicalized theyshould notbe subjected
to humidity for long periods.
WARNING - ForHazardous Areas installations,
at least eight (8) threads on each cover must be
engaged in order for the transmitter to meet
(flameproof - explosion-proof) requirements.
