CONTENTS 1. INTRODUCTION
This document provides basic instruction for the installation
and commissioning of the ABB 2600T. This transmitter is
connected to a process by means of impulse lines and can
measure Pressure or Absolute pressure. The measurement is
transmitted to a control system by means of a 4-20 mA signal
with a superimposed digital signal (HART) or by means of a
digital transmission protocols. The measure can also be
indicated by means of one of the (optional) local or remote
displays.
Instructions for preliminary checks, proper transmitter location,
installation, wiring, power-up and zero calibration (trimming) of
the transmitter are listed in the following.
In order to assure operator and plant safety it is essential that
the installation is carried out by personnel suitably trained on
the local applicable codes on hazardous location, electrical
wiring and mechanical piping. Please read these instructions
carefully before installing the transmitter. The protection
provided by the equipment may be impaired if the equipment
is used in a manner not specified.
For more information refer to the reference manual (document
268H/N HART Pressure Transmitters - Operating Instruction ).

2. PRELIMINARY CHECKS
Before mounting the transmitter, check the compatibility with
the following measurement and safety requirements:
-Explosion protection
-Pressure rating
-Operating voltage limits
-Process and ambient Temperature limits
-Environmental limits
-Corrosion
2.1 EXPLOSION PROTECTION
Explosions could result in death or serious injury. Installation
of this transmitter in a Hazardous Area (i.e. a potentially
explosive atmosphere) must be in accordance with the
appropriate local, national, and international standards, codes,
and practices.
Please review the approvals and marking of the transmitter
shown on the label attached to the transmitter (see figure 1 -
Ref. C), note that this is a sample, read the values on the real
label; if this label is not present, the instrument is not suitable
for installation in Hazardous Areas. It is necessary to check
that all the parameters listed on this label (or on the certificates
enclosed with the transmitter) are in accordance with the
requirements of the area where the transmitter is going to be
installed. See the reference manual for an explanation of each
parameter related to "EX SAFETY". In case of any discrepancy
do not install the transmitter.
For pressure transmitter with ATEX combined approval, before
installation, the transmitter should be permanently marked with
the selected Protection Concept (e.g. intrinsically safe or
explosion proof) on the safety label. The transmitter can be
used only in accordance with this Protection Concept for its
whole life.
Note - 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. In
this case it is recommended to select the correct fail safe
mode for the 4-20 mA signal (as per Namur NE43
recommendation). See also the instructions relevant to
fail safe selection (Up/Down scale mode) in the addendum
to the instruction manual on "Use of hardware links on the
secondary electronics" .

PHASE 1 - PRELIMINARY CHECKS
WARNING ! - In order to assure the proper
containment of the process fluid by the transmitter, it is
recommended that any part, related to process fluid
containment, be supplied only by ABB or authorized agents.
The spare parts list is available at: http://138.221.224.36
searching for “SL/26*” or from local ABB representatives.
The storage conditions must be within the following limits,
Lower limit: –50°C (–58°F); –40°C (–40°F) for LCD indicators
Upper limit: +85°C (+185°F) otherwise some material such as
gaskets may be damaged and cannot assure proper fluid
containment.
2.3 OPERATING VOLTAGE LIMITS
The transmitter is designed to provide a current transmission
signal of 4 to 20 mA dc on the same wires that are carrying the
power supply (two-wire transmitter).
The transmitter operates on a minimum voltage of 10.5 Vdc to
a maximum of 42 Vdc and is protected against polarity inversion.
The transmitter operates from 10.5 to 42 Vdc with no load.
Some communication problems may occur, in cases the loop
resistance is increased by long wires or additional devices like
meters, safety barriers, surge protection, remote indicators,
etc.. If this is the case, please refer to the reference manual for
further details (the manual is available at www.abb.com inserting
in the “search” tool the keyword “IM/26X”) or from local ABB
representatives.
For EEx ia and intrinsically safe (FM, CSA and SAA) approvals,
the power supply must not exceed 30 Vdc. In some countries
the maximum power supply voltage is limited to a lower value.
The transmitter insulation resistance (terminals to earth) is
>100MΩ at 1000VDC.
CAUTION Do not arc-weld any pipe-connected to
the transmitter as this could break the electrical insulation
and damage the electronic part of the transmitter.

2.5 CORROSION
Be sure that the process fluid is compatible with the material of
the process flanges and sensor diaphragm.
A fluid / material compatibility table is available at www.abb.com
(inserting in the “search” tool the keyword “TB/COR”) or from
local ABB representatives.
NOTE
Data of the 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-concentration profile, stress corrosion cracking
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
0.04 in. Therefore from the viewpoint of safe containment
of liquids compatible with a specific material according to
the table, the expected instrument lifetime is more than 10
years, but the previous note apply.
2.6 SPECIAL SERVICES
In case of Oxygen or Hydrogen or other special services, the
transmitter has to be handled with a special care in order to
prevent contamination with impure substances. It is
recommended to use “sterile” gloves and that the removal of
protection bags be done only immediately before the installation.
Do not flush with impure fluids.

3.2 TRANSMITTER MOUNTING
Orient the process flanges to enable process connections to be
made.
It is important to mount the transmitter and to lay the process
piping so that gas bubbles, when measuring liquids, or
condensate when measuring gases, can flow back into the
process.
The vent/drain screw valves has to be ordered higher than the
taps on liquid service in order to allow the venting of entrapped
gas or below the taps on gas service in order to allow the drain
of condensate.
For safety reasons, orient the drain/vent valves so that process
fluid is directed down and away from technicians when the
valve is used. This can be accomplished by pointing the hole
in the outside valve body downward and away. In addition,
consider the need for a testing or calibration input, and provide
space for the housing covers to be removed for electrical wiring
and maintenance.
WARNING !
Process leaks may cause harm or result in death.
Install and tighten process connectors and all accessories
(including manifolds) before applying pressure.
In case of toxic or otherwise dangerous process fluid, take
any precautions as recommended in the relevant Material
Safety Data Sheet when draining or venting.
Use only a 12 mm (15/32 “) hexagonal spanner to tighten
the bracket bolts.
