3.2 Range & Span consideration
The 2600T Transmitter Specification Sheets provide all information concerning the Range and Span limits in relation to
the model and the sensor code.
The terminology currently used to define the various parameters is as follows:
URL: Upper Range Limit of a specific sensor. The highest value of the measured value that the transmitter can
be adjusted to measure.
LRL: Lower Range Limit of a specific sensor. The lowest value of the measured value that the transmitter can
be adjusted to measure.
URV: Upper Range Value. The highest value of the measured value to which the transmitter is calibrated.
LRV: Lower Range Value. The lowest value of the measured value to which the transmitter is calibrated.
SPAN: The algebraic difference between the Upper and Lower Range Values. The minimum span is the
minimum value that can be used without degradation of the specified performance.
TD: (or Turn Down Ratio) is the ratio between the maximum span and the calibrated span.
The transmitter can be calibrated with any range between the LRL and the URL with the following limitations:
LRL ≤ LRV ≤ (URL - CAL SPAN)
CAL SPAN ≥ MIN SPAN
URV ≤ URL

4.1 Identification
The instrument is identified by the data plates shown in
Figure 2. The certification plate (ref. A): contains the
certification related parameters for use in Hazardous area.
The Nameplate (ref. B), always made of AISI 316 ss, provides
information concerning the model code, maximum working
pressure, range and span limits, power supply, output signal,
diaphragms material, fill fluid, range limit, serial number,
maximum process working pressure (PS) and temperature
(TS).
The Tag plate, instead, provides customer tag number and
calibrated range.
Both certification and tag plates are supplied self-adhesive
attached to the electronics housing, as standard. Option I2
allows to select these plates as metal AISI 316 ss fastened to
the electronics housing with rivets.
The instrument may be used as a pressure accessory
(category III) as defined by the Pressure Equipment Directive
2014/68/EU. In this case, near the CE mark, you will find the
number of the notified body (0474) that have verified the
compliance. 266 pressure transmitters are in compliance
with EMC 2004/108/CE*.

subject to a conformity validation. These instruments were
designed and manufactured acc. to SEP Sound
Engineering Practices.
5 Mounting
5.1
Study these installation instructions carefully before
proceeding. Failure to observe the warnings and
instructions may cause a malfunction or personal hazard.
Before installing the transmitter, check whether the device
design meets the requirements of the measuring point
from a measurement technology and safety point of view.
This applies in respect of the:
— Explosion protection certification
— Measuring range
— Gauge pressure stability
— Temperature (Ambient and Process)
— Operating voltage
The suitability of the materials must be checked as regards
their resistance to the media. This applies in respect of
the:
— Gasket
— Process connection, isolating diaphragm, etc.
In addition, the relevant directives, regulations, standards,
and accident prevention regulations must be observed
(e.g., VDE/VDI 3512, DIN 19210, VBG, Elex V, etc.).
Measurement accuracy is largely dependent on correct
installation of the pressure transmitter and, if applicable,
the associated measuring pipe(s). As far as possible, the
measuring setup should be free from critical ambient
conditions such as large variations in temperature,
vibrations, or shocks.
Important. If unfavorable ambient conditions cannot be
avoided for reasons relating to building structure,
measurement technology, or other issues, the measurement
quality may be affected. If a remote seal with capillary tube is
installed on the transmitter, the additional operating
instructions for remote seals and the related data sheets must
be observed.
5.2
The housings for 266 transmitters are certified as
conforming to protection type IP66 / IP67 (according to
IEC 60529) or NEMA 4X (according to NEMA 250).
The first number indicates the type of protection the
integrated electronics have against the entry of foreign
bodies, including dust.
“6” means that the housing is dust-proof (i.e., no ingress
of dust).
The second number indicates the type of protection the
housing has against the entry of water.
“6” means that the housing is protected against water;
specifically, powerful jets of water under standardized
conditions.
“7” means that the housing is protected against water;
specifically, against the effects of temporary immersion in
water under standardized water pressure and temporal
conditions.
5.3
5.3.1 Transmitter factory configuration consideration
The 266 pressure transmitter in your hands has been
factory calibrated to reflect the published declared
performance specification; no further calibration is
required in normal condition. ABB typically configures 266
pressure transmitters according to the user requirements.
A typical configuration includes:
— TAG number
— Calibrated span
— Output linearization
— LCD display configuration
5.3.2
The transmitter must be installed in hazardous area only if
it is properly certified. The certification plate is
permanently fixed on the neck of the transmitter top
housing.
Warning - General Risk for model 266 used in zone 0.
The enclosure contains aluminum and is considered to present a
potential risk of ignition by impact or friction. Care must be
taken into account during installation and use to prevent impact
or friction.

6 Setup
6.1 Temperature measurement
— Mount the temperature sensor in the downstream pipe
of the primary element.
— Consider the downstream straight pipe requirements.
— If there is a significant difference between the
temperature of the measuring medium and the
ambient temperature, the measuring error caused by
heat conduction must be minimized by insulating the
installation location accordingly.
— Use class “A” sensors to maximize accuracy.
6.2 General information
The relevant directives must be complied with for the
electrical installation! Because the transmitter cannot be
switched off, surge protection devices, lightning
protection, or grid disconnect possibilities must be
provided at the plant.
Check that the existing supply voltage corresponds to that
indicated on the rating plate. The same lines are used for
both the power supply and the output signal.
If an optional surge protector is provided and if the
transmitter is used in a hazardous area, energy must only
be supplied via a voltage source with electrical isolation
from the grid. Because the inherently safe power circuits of
the transmitter are grounded, a sufficient equipotential
bonding must be ensured for the entire supply line.
8.6.3 Installing the connecting cables
Ensure that a drip loop (water trap) is used when installing
the connecting cables for the sensor.
If necessary, rotate the transmitter housing accordingly..
NOTICE
If cable glands are not used, the red transport screw
plugs must be replaced with suitable screw plugs when
the transmitter is installed. This is because the transport
screw plugs are not certified as protected against
explosion. This requirement is particularly relevant in
hazardous areas
Cable entries with an M20 x 1.5 thread
Devices with an M20 x 1.5 thread are optional supplied
with factory-installed cable glands and sealing plugs.
Cable entries with a 1/2” NPT thread
The supplied transport sealing plugs do not have IP
rating 4X / IP67 and are not approved for use in
potentially explosive atmospheres.
The transport sealing plugs must be replaced with
suitable cable glands or sealing plugs during device
installation. When selecting the cable glands or sealing
plugs, make sure they have the required IP rating and
explosion protection!
To offer IP rating 4X / IP67, the cable glands / sealing
plugs must be screwed in using a suitable sealing
compound.
Cable entry for PT100 temperature sensor
A metal cable gland should always be used for the Pt100
cable since a shielded cable is used.
Connect the shielding within the metal cable gland!
To offer IP rating 4X / IP67, the cable glands / sealing
plugs must be screwed in using a suitable sealing
compound.

of wiring no 18 to 22 AWG / 0.8 to 0.35mm2 ø up to 5,000
feet (1500 meters). Longer loops require larger wire.
If a shielded wire is used, the shield should be grounded
only at one end, not both ends. In case of wiring at
transmitter end, use the terminal located inside the
housing marked with the appropriate sign.
For Ex ia and other intrinsically safe approval power supply
must not exceed 30 V DC.
Minimum operating voltage increase to 12.3 V DC with
optional surge protector or to 10.8 V DC with optional
conformity to NAMUR NE 21 (2004).
For maximum power supply voltage please refer to the top
identification plate of the transmitter.
The actual possible line length of the electrical circuit
depends on the total capacitance and resistance, and can
be estimated using the following formula:
6.3 Cable entries
The electrical connection is made via cable entries with a
1/2” NPT or M20 x 1.5 thread.

6.5 Grounding
Pressure transmitter housing should be grounded or
earthed in accordance with national and local electrical
codes. Ground connection is mandatory for surge
protector equipped devices in order to ensure proper
functioning.
Protective grounding terminals (PE) are available outside
and/or inside the housing of the transmitter. Both ground
terminals are electrically connected and it up to the user to
decide which one to use. The most effective transmitter
case grounding method is direct connection to earth
ground with impedance equal or less of 5 ohm.

Cable specification
The maximum permissible length depends on the baud
rate, the cable (diameter, capacity and surge impedance),
the number of loads in the device chain, and the network
configuration (2-core or 4-core).
— At a baud rate of 9600 and with a conductor cross
section of at least 0.14 mm2 (AWG 26), the maximum
length is 1000 m (3280 ft).
— If a 4-core cable is used in a 2-wire system, the
maximum length must be halved.
— The spur lines must be short (maximum of 20 m
[66ft]).
— When using a distributor with “n” connections, the
maximum length of each branch is calculated as follows:
40 m (131 ft) divided by “n”.
The maximum cable length depends on the type of cable
used. The following standard values apply:
—Upto6m(20ft):cablewithstandardshieldingortwisted-
pair cable.
— Up to 300 m (984 ft): double twisted-pair cable with
overall foil shielding and integrated earth cable.
— Up to 1200 m (3937 ft): double twisted-pair cable with
individual foil shielding and integrated earth cables.
Example: Belden 9729 or equivalent cable.
A category 5 cable can be used for Modbus RS485 up to a
maximum length of 600 m (1968 ft). For the symmetrical
pairs in RS485 systems, a surge impedance of more than
100 Ω is preferred, especially at a baud rate of 19,200 and
above.
Using the Modbus protocol allows devices made by
different manufacturers to exchange information via the
same communication bus, without the need for any
special interface devices to be used.
Up to 32 devices can be connected on one Modbus line.
The Modbus network can be expanded using repeaters.

6.8 Write Protection
Write protection prevents the configuration data from
being overwritten by unauthorized users.
If write protection is enabled, the “Z” and “S” buttons
(both internal or external) are disabled. However, it is still
possible to read out the configuration data using the
graphical user interface (DTM) or another, similar
communication tool. The control unit may be leaded if
required.
7.3.1 Write protection activation via external push button
When the instrument features the external non-intrusive
push buttons (digit R1 within instrument code), the write
protection function can be performed as follows:
— Remove the identification plate (see figure 17) by
releasing the holding screw lying on the bottom left
corner.
— Use a suitable screwdriver to press the switch down
fully. (see figure 14)
— Then turn the switch clockwise by 90°.
6.8.1 Write protection activation via dip switch
Standard instruments do not feature the external, non
intrusive Zero, Span and Write Protection push buttons. To
activate this function it is necessary to proceed as
detailed below:
— Remove instrument cover and the integrated digital
LCD display (if installed).
— On the connection board, place dip switch 4 in “up”
position.
6.9 Correcting the lower range value / zero shift
During installation of the transmitter, transmitter, zero
shifts caused by mounting (e.g., a slightly oblique
mounting position due to a remote seal, etc.) may occur;
these must be corrected.
Important. The transmitter must have reached its operating
temperature (approx. 5 min. after startup, if the transmitter
has already reached the ambient temperature) in order to
perform zero shift correction. The correction must be made at
dp (or p) = 0.
Important. The button unit must be available for this purpose
(option R1). In case external push buttons are not available, act
on the connection board directly by depressing with a
screwdriver the dedicated internal push buttons. Operating
the buttons using a magnetic screwdriver is not permitted
because it may generate some interferences with the magnetic
pickup system.
Set Lower Range Value
— Apply the lower range value pressure from the process or
from a pressure transducr. The pressure must be stable and
applied with a high level of accuracy <<0.05% (observing
the set damping value)
— Press the “Z” button (external pushbutton - option R1)
6.10 Correct the zero shift
The zero shift caused by the installation may be cancelled
in different ways:
— Pressing the “Z” button (under the identification plate
on the top of the transmitter, if present) or the “Zero”
internal button (on the connection board) for few
seconds will cause the output to go at 4 mA.
— It is also possible to align the digital PV value to zero.
To accomplish it raise the dip sw. 3 on the communication
board to the up (1) position and press the zero button.This
functionality will align the PV digital value to 0 and if the
calibrated span it is zero based, the output will go at 4
mA.
— Using the optional LCD with keypad (“Configuration
of the pressure transmitter using the integral LCD
HMI” for further information).
Important. In case of electronics change to Standard to Advanced HART
(refer to chapter 9.6), external, non-intrusive push buttons can be
installed (if not selected with the option R1) by ordering the commercial
code DR1014. Please refer to local ABB representative.

Important. All of the configurable parameters here on the left
can easily be modified either via the optional LCD HMI, with a
HART handheld terminal or a compatible software solution.
Information regarding flange type and material, O-ring
materials, and filling liquid type is stored inside the non-
volatile memory of the device.
7.3 Configuration types
Pressure transmitters can be configured as follows:
— Configuration of the parameters for the lower and
upper range values (via Zero and Span push buttons),
without an integral LCD HMI.
— Configuration of the pressure transmitter using the
integral LCD HMI with keypad (menu-controlled).
— Configuration with a handheld terminal.
— Configuration using a PC/laptop via the graphical
user interface (DTM).

7.4 Configuring the transmitter without an
integral LCD HMI
The “lower range value” and “span” parameters can be set
directly on the transmitter using the external or internal
push buttons.
The transmitter has been calibrated by the manufacturer
based on the order information. The tag plate contains
information on the “lower range value” and “upper range
value” set. In general, the following applies:
Important. Reducing station with adjustable pressure and
reference displays can be used as pressure generators.
When making the connection, please ensure that there are no
residual fluids (for gaseous testing materials) or air bubbles
(for fluid testing materials) in the impulse lines, since these
can lead to errors during inspection. Any potential measuring
error for the pressure generator should be at least three times
smaller than the desired measuring error for the transmitter. It
is recommended that the damping is set to 1 second.

7.8 LCD (L1 and LS option) activation considerations
Gain access to the display by unscrewing the windowed cover. Please observe the Hazardous area prescription before
proceeding with the cover removal. For activation, see below.
7.9 Through The Glass (TTG) (L5 option) activation considerations
The TTG technology allows the user to activate the keypad on HMI without the need of opening the windowed cover of
the transmitter. The capacitive pick-ups detect the presence of a finger in front of the respective button activating the
specific command. At the transmitter power-on the HMI automatically calibrate its sensitivity, it is mandatory for proper
functioning of the TTG HMI that the cover is properly tightened at power-on.
Important. Do not operate TTG display (L5 option) for 30 seconds after
transmitter power-on. During this period of time, the transmitter is
calibrating the capacitive switches.
