Important - The instrument serial number must always be quoted when making enquiries.
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 process working pressure (PS) and
temperature (TS), range and span limits , power supply and
output signal. See also the "Operative Limits" section in the
following.Thisplatealsoshows thetransmitterserialnumber.
Please refer to this number when making enquiries.

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
indicator.

WARNING
In order to ensure operator safety and plant safety it is
essential that installation is carried out by suitably
trained personnel according to the technical data
provided in the "Operative Limits" section in the
following of the document.
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.

Note: High side may be marked H or +
Low side may be marked L or -
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 safety information hereandafter 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 shouldnotbeinstalled
where it may be subjected to mechanical and thermal
stresses or where it may be attached by existing or
foreseable aggressive substances.
ABB cannot guarantee that a construction material is
suited to a particular process fluid under all possible
process conditions. See also the paragraph on "Operati-
ve limits".

OPERATIVE LIMITS
Thetransmitteroperatesonaminimumvoltageof10.5Vdcto
a maximum of 55 Vdc and is protected against polarity
inversion.
Note - The transmitter operates from 10.5 to 42
Vdc with no load (a load up to 620 Ωallows operation
up to 55 Vdc). For EEx ia and intrinsically safe (FM,
CSA and SAA) approval power supply must not
exceed 30 Vdc.In some countries the maximum
power supply voltage is limited to a lower value.
Installing optional devices the minimum voltage increases to:
- 10.5 Vdc with no option or with integral digital display
- 10.7 Vdc with output analog indicator
- 12.5 Vdc with output LCD indicator
- 12.1 Vdc with surge protection
- 14.1 Vdc with LCD indicator and surge protection
- 13.1 Vdc with LCD CoMeter
The total loop resistance is indicated in the figure and
expression below.
The total loop resistance is the sum of the resistance of all
elements of the loop, including wiring, conditioning resistor,
safety barriers and additional indicators (excluding the
equivalent resistance of the transmitter).
Where a configuration device (HART), such as the Hand Held
Communicatoror aModemis likelytobe used,aresistance of
250 ohm minimum should be present between the power
supply and the point of insertion of these devices, to allow
communication.
Severaltypesofsafetybarriers,eitherpassiveoractive,canbe
satisfactorily used in conjunction with the Smart 600T EN
transmitter. Nevertheless, in case of use of active barriers,
check with the supplier if the model is suitable for use with
smarttransmittersallowingtheconnectionoftheconfiguration
devices in the "safe" or non-hazardous area.
WARNING - The transmitter may be used as a
safety accessory (as defined by the Pressure Equipment
Directive 97/23/EC) i.e. as part of a shutdown system.

NOTE
Data of the following table are based on information from
manufacturers.
All data is based on a temperature of 20 °C, 70 °F unless
noted otherwise.
Since corrosion involves many more variables than this
table considers, such as trace contaminants, aeration or
temperature-concentrationprofile,stresscorrosioncracking
and pitting, the table should be used only as a reference in
narrowing the choice of materials that merit further
investigation. Suitability of a particular material is best
determined by field test.
At this purpose, please contact our local ABB
representatives.
WARNING
For safety purpose the design corrosion allowance of
differential pressure instrument flanges is of about 1.5 mm

DISMANTLING AND REASSEMBLY
WARNING - Process fluids and/or pressure
retained in the transmitter primary unit can cause
severe injury and death or damage to the equipment.
It is the user responsibility to make sure that the
instrumentisnotunderpressurebeforeremoving the
instrument from service or when draining or venting.
Dangerous fluids
Incase of toxic or otherwisedangerousprocess fluid,
takeanyprecautionsasrecommendedintherelevant
Material Safety Data Sheet.
CAUTION - Dismantling and reassembly should
not be carried out on site because of the risk of
damagetocomponentsandprintedcircuitsasaresult
of adverse environmental conditions such as
humidity,dust,etc. The dismantling and reassembly
procedures given below should be carried out in the
listed order to avoid instrument damage.
Required tools
2 mm Allen key
3 mm Allen key
Small Phillips screwdriver
Small flat-bladed screwdriver
17 mm spanner (22 mm for mod. 622ED)
17 mm torque wrench (22 mm for mod. 622ED)
- (Range > 52 Nm - 39 foot lbs)
Dismantling
a) Screwdowncompletelythecoverlockingscrew,electronics
side, using the 3 mm Allen key
b) Unscrew and remove the covers
c) Unscrew the two fixing screws and remove the
secondary electronic assembly
d) Unplug the sensor cable
e) Remove the tang grub screw using the 2 mm Allen key
f) Unscrew the housing taking care not to damage the
sensor cable or the connector
g) Loosen and remove the four flange fixing bolts using a
17 mm. spanner (22 mm for mod. 622ED).
Reassembly
Check that the "O" rings are not damaged : if in replace.
WARNING - Assembling flanges with incorrect
fixingboltsandnutsandimproper"Orings"cancause
fracture or overstressing of bolts and release of
pressurized process material. Use only official spare
parts(*)anddonotexceedthespecifiedtorquelimits.
DO NOT REMOVE the "O ring" fitted in the sensor
neck: it provides the housing a degree of protection.
a) Refittheflangefixingboltswithatorqueof20Nm(15ftlbs)
using a 17 mm. torque wrench (52 Nm - 39 ft lbs for mod.
622, using a 22 mm torque wrench).
1 Nm is equivalent to 0.738 ft lbs (8.85 in lbs)
b) Insert the sensor cable in its recess at the bottom of the
housing.
c) Screw the housing down completely until the nesting of
housing/sensor assy is reached, then unscrew by one
complete turn maximum. Rotate the topwork in the
desired position and lock it with the tang grub screw
previously removed.
d) Plug the sensor cable to the secondary electronics. Fix
the electronic circuit by its screws.
e) Refit the covers and tighten securely.
WARNING-ForHazardousLocationinstallations,
