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.
3 Transmitter overview
The transmitter can be calibrated with any range between the
LRL and the URL with the following limitations:
LRL ≤ LRV ≤ (URL - CAL SPAN)

5.1 General
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
— 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 IP protection & designation
The housings for 266 transmitters are certified as conforming to
protection type IP66 / IP67 (according to IEC 60529).
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 integrated electronics have against the entry of water.
5.3 Mounting the transmitter
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 Hazardous area considerations
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. The 266 Pressure
Transmitter Line can have the following certifications:
ATEX INTRINSIC SAFETY

Warning - General risks. Unused port plug must be in accordance
with the intended type of protection (e.g. intrinsically safe, explosion
proof, etc.) and degree of protection (e.g. IP6x according to IEC EN
60529). See also the addendum for “EX SAFETY” ASPECTS AND
“IP” PROTECTION. In particular, for explosion proof installation,
remove the red temporary plastic cap and plug the unused opening
with a plug certified for explosion containment
Warning - General risks. Model 266 enclosure contains aluminium
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.
The second number indicates the type of protection the hosing
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

5.5 Mounting a DP sensor transmitter
(266DS/266DR)
The pressure transmitter model 266DS can be mounted directly
on the manifold. A mounting bracket for wall or pipe mounting
(2” pipe) is also available as an accessory. For model 266DR
always mounting brackets should be used. Ideally, the pressure
transmitter should be mounted in a vertical position to prevent
subsequent zero shifts.
piping so that gas bubbles, when measuring liquids, or
condensate when measuring gases, will flow back to the
process and not enter the transmitter measuring chamber.
Optional Vent/drain valves (code V1/V2/V3) on the transmitter
are located on the sensor flanges.
The transmitter has to be positioned so that these drain/vent
valves will be located 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 air to vent off or
condensate to drain off. For safety reasons, take care of the
drain/vent valves position so that when the process fluid is
removed during the drain/vent operation it is directed down
and away from technicians. It is recommended to mount the
transmitter to prevent this possible source of damage for
unskilled operators.
Figure 5: Drain/vent valves configuration (respectively V1, V2, V3)
Important. In case of a High Static differential pressure transmitter,
please notice that the Vent/Drain valves can be configured only on
the process axis (V1).
Important. If the transmitter is installed inclined with respect to the
vertical, the filling liquid exerts hydrostatic pressure on the
measuring diaphragm, resulting in a zero shift. In such an event, the
zero point can be corrected via the zero push-button or via the “set
PV to zero” command. Please refer to the [configuration section] for
further details. For transmitters without diaphragm seals, please
read the following considerations on the Vent/Drain.
Attention − Potential damage to transmitter. In case of a High
Static differential pressure transmitter (266DSH.x.H) please always
open the equalization valve of the manifold (if installed) before
applying pressure to the transmitter. High Static pressure can
damage the sensor causing a zero shift and a serious decrease of
the total performance in terms of accuracy. In this case, please
perform a full sensor trim.
It is important to mount the transmitter and to lay the process

5.7 Transmitter housing rotation
To improve field access to the wiring or the visibility of the
optional LCD meter, the transmitter housing may be rotated
through 360° and fixed in any position. A stop prevents the
housing from being turned too far. In order to proceed with
housing rotation, the housing stop tang-screw has to be
unscrewed by approximately 1 rotation (do not pull it out) and,
once the desired position has been reached, retightened.
Figure 18: Housing rotation
5.8 Integral display rotation
In case an optional integral display meter is installed, it is
possible to mount the display in four different positions rotated
clockwise or counterclockwise with 90° steps. To rotate the
LCD, simply open the windowed cover (Hazardous area
prescriptions must be respected), pull-out the display housing
from the communication board.. Reposition the LCD connector
according to the new desired position. Push back the LCD
module on the communication board. Be sure that the 4 plastic
fixing locks are properly in place.
5.10 Impulse piping connection for standard
instruments
In order for the pipes to be laid correctly, the following points
must be observed:
— The measuring pipes must be as short as possible and
free from sharp bends.
— Lay the impulse piping in such a way that no deposits
accumulate in them. Gradients should not be less than
approx. 8% (ascending or descending).
— The measuring pipes should be blown through with
compressed air or, better yet, flushed through with the
measuring medium before connection.
— Where a fluid/vaporous measuring medium is being used,
the liquid in both measuring pipes must be at the same
level. If a separating liquid is being used, both measuring
pipes must be filled to the same level (266Dx).
— Although it is not absolutely necessary to use balancing
vessels with vaporous measuring media, measures must
be taken to prevent steam entering the measuring
chambers of the measuring equipment (266Dx).
— It may be necessary to use condensate vessels, etc., with
small spans and vaporous measuring media (266Dx).
— If using condensate vessels (steam measurement), you
should ensure that the vessels are at the same elevation
in the differential pressure piping (266Dx).
— As far as possible, keep both impulse lines at the same
temperature (266Dx).
— Completely depressurize the impulse lines if the medium
is a fluid.
— Lay the impulse lines in such a way that gas bubbles
(when measuring fluids) or condensate (when measuring
gases) can flow back into the process line.
5.9 Antenna rotation
Usually the antenna should be turned into a vertical or
horizontal positions. The antenna must not be rotated more
than 360° in order to not prevent HF wires inside the
transmitter from damaging. Please refer to the pictures below
to identify wireless signal coverage areas.
— Ensure that the impulse lines are connected correctly
(High and Low pressure sides connected to measuring
equipment, seals...).
— Make sure the connection is tight.
— Lay the impulse line in such a way that prevents the
medium from being blown out over the measuring
equipment.
Caution. 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.

5.11 Process connections considerations
266 differential pressure transmitter process connections on
the transmitter flange are 1/4 - 18 NPT, with a centers distance
of 54mm (2.13in) between the connections. The process
connections on the transmitter flange are on centers to allow
direct mounting to a three-valve or five-valve manifold.
Flange adapter unions with 1/2 - 14 NPT connections are
available as an option. Rotate one or both of the flange
adapters to attain connection centers of 51mm (2.01in), 54mm
(2.13in) or 57mm (2.24in).
To install adapters, perform the following procedure:
1. Position the adapters with the O-ring in place.
2. Bolt the adapters to the transmitter using the bolts
supplied.
3. Tighten the bolts to a torque value of 25Nm (stainless
steel bolts) or 15Nm (for Stainless steel NACE bolts).
For high static model (266DSH.x.H) tighten the bolts to a
torque value of 40 Nm (regardless of the material of the bolts
used). In case of PTFE O-rings, pretightening to 10Nm and final
tightening to 50 Nm.
5.12 Kynar inserts connection
When connecting Pressure transmitters equipped with kynar
inserts tighten the bolts to 15 Nm max.

Field devices can communicate with Asset Vision Basic wirelessly through the Gateway connected via Ethernet TCP/IP 1.
The Gateway communicates to the DCS (Distributed Control System) via Modbus RS485 4.
6.2 Design and function
Wireless HART transmitters provide an FSK maintenance port too, compatible with existing tools such as modems and handheld
terminals with the purpose of configuration and maintenance. Anyway, its main communication interface is wireless. The same
protocol is used to communicate with a wireless HART compatible gateway. The gateway provides different kinds of wired
interfaces and protocols such as RS-485 or Ethernet.
The transmitters can be configured, polled, and tested using a DTM or an EDD via both, the wired and the wireless interface.

Important.
HART hand-held communicator may be connected
at any termination point in the loop. No need of 250 ohms
resistance for communication purposes.
6.4 Supply requirement
Pressure transmitter power supply is granted by a 3.6V size ‘D’
battery. Standard supplied battery is a Lithium-thionyl chloride
cell certified for Hazardous Areas.
6.5 Powering the transmitter on
Follow these steps to power the transmitter on:
— Remove the temporary plastic cap from one of the two
electrical connection ports located at both sides in the
upper part of the transmitter housing.
— This connection port has a M20 threads. Dedicated plug
has to be fitted to this port to comply with plant standards.
Important.
266 Pressure Transmitter is certified IP67. To
maintain the IP67 certification rating, it is necessary to select
the dedicated plug.
— Remove the housing cover of the “field terminals” side.
See the indication engraved on one side of the housing.
— Remove the battery pull-tab grabbing it firmly and pulling
it completely outside from its slot. This will allow the cell to
make contact with the electronic module.
Note.
266 WiPressure battery is manufactured by TADIRAN
Batteries GmbH (manufacturer code SL 2780)
— Before installing the huosing cover, check whether the
display is working or not. If yes, put back the housing
cover, turn it to seat O-ring into the housing and then
continue to hand tighten until the cover contacts the
housing metal-to-metal.
6.6 Protective 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.

7 Commissioning
Once the transmitter has been installed, it is put into operation
by enabling the battery. Check the following before switching
on the operating voltage:
— Process connections
— The impulse line/s and the measuring chamber of the
measuring equipment must be completely filled with the
measuring medium.
The transmitter can then be put into operation. To do this, the
shut-off valves must be actuated in the following sequence (in
the default setting, all valves are closed).
(Differential models) 266Dx
— Open the shut-off valves on the pressure tap connection
— Open the pressure equalization valve of the manifold.
— Open the positive shut-off valve (on the manifold)
— Open the negative shut-off valve (on the manifold)
— Close the pressure equalization valve.
To put the transmitter out of operation, carry out the steps in
reverse order.
7 Commissioning
The write protection function can be performed as follows:
— Remove the ID (see figure 3 at chapter 4) by releasing the
holding screw lying on the bottom left corner.
— Turn ON device LCD (if installed) by pressing “Z” button and
check if the lock icon
— Use a suitable screwdriver to press the switch down fully.
— Then turn the switch clockwise by 90°.
Important. To deactivate the switch, push it down slightly and then
turn counterclockwise by 90°.
Important. To activate or de-activate the Write Protection function,
instrument shall be live. To make instrument go live, press “Z”
button for two seconds and wait for the display to turn on.
is displayed.
(Gauge & Absolute models) 266Hx, 266Nx
— Open the shut-off valve on the pressure tap connection
— Open the positive shut-off valve.
To put the transmitter out of operation, carry out the steps in
reverse order.
Important. Please be aware that the measuring equipment will
have been overloaded by the atmospheric pressure due to the long
periods of transport and storage involved.
For this reason, you will need to allow a starting time of approx. 30
minutes for 266Nx models after commissioning, until the sensor
has stabilized to such an extent that the specified accuracy can be
maintained.
Only passive devices or indicators may be connected.
7.1 Standard setting for normal operation
In order to prevent errors in flow rate measurements (266Dx) in
the lower range, it is possible to set a “cut off point” and/or a
“lin./sq. root transition point” via the optional LCD integral
displays with keypad or via external tools (DD file or DTM).
Unless otherwise specified, the “lin./sq. root transition point” is
set to 5% and the “cutoff” to 6% of the flow rate end value by
the manufacturer.
7.2 Standard setting for error detection (alarm)
External tools (DD file on handheld terminal or DTM) or the LCD
integral display (if installed) can be used to diagnose the error.
Important. A brief interruption in the power supply results in
initialization of the electronics (program restarts).
7.3 Write Protection
Write protection prevents the configuration data from being
overwritten by unauthorized users. If write protection is enabled,
the “Z” and “S” buttons are disabled. However, it is still possible
to read out the configuration data using communication tools
such as DTM or DD file on an handheld terminal. The control unit
may be leaded if required.
Figure 32: Write-protection pushbutton
7.4 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.
7.5 Correct the zero shift
The zero shift caused by the installation can be cancelled in
different ways:
— By acting on the external push button “Z” with live
instrument to align the PV digital output.
— By using the optional LCD with keypad (“Configuration of
the pressure transmitter using the integral LCD HMI” for
further information).
To correct the zero shift using “Z” push button:
— Wake up the instrument by pressing “Z” push button for
at least 2 seconds, then release it
— The HMI should Turn ON (if installed)
— Now press the Z again for at least 2 seconds
— When it is released the PV digital output is zeroed.

7 Commissioning
7.6 Joining the network
In order to allow the wireless communication between
transmitter and gateway the transmitter shall join the network
configuring the relevant parameters Network ID and Join Key.
This initial basic setting can be done using:
— Asset Vision Basic via HART modem wired connected to
the device terminals
— Hand-held terminal wired connected to the device terminals
— The local HMI menu.
Usually 3 parameters should be set always during first
commissioning to alow a device to join a network:
— Network-ID. The network-id is the identifier of a network
and must be the same for all devices within the same
network including the gateway. There might be other
networks in parallel but they need to have a different
network-id. The network ID is a 16 bit wide number.
— Join-Key. The join key is important to authorize a device
joining the network. It serves for network security. The join
key can be the same for different networks. The join key is
a security relevant information and should protected as
such. Wireless HART allows individual join keys for the
wireless devices in the network what serves for higher
security but has also impact on maintenance effort. Not all
gateways may support individual join keys. The join key is
a set of four 32 bit wide numbers (128 bit in total).
— HART Long-TAG: This is human readable identifier of the
device in the network and is almost used by a getway to
build a device list (“live list”) of the network. The HART
Long-TAG shall be unique for every device in the network.
Some gateways notify when doubled long TAGs are
identified. As the HART Long-TAG is 32 characters long it
is suitable to serve as a unique identifier of a single device
in a whoile plant / installations and not just within the
wireless HART network. By default, 266 Pressure
Transmitters are delivered with a unique HART Long-TAG
containing part of the devices serial number and therefore
there is no need to set the HART Long-TAG. HART Long-
TAG is necessary for the communication via Ethernet TCP/
IP within the Asset Vision Basic projects
In case network ID and join key already match the settings of
the gateway e.g. due to prior configuration or default settings
are used, there is no need for any further adjustments. 266
WirelessHART will join a reachable network automatically.
7.7 Burst
7.7.1 Burst configuration
Once the device is in the newtwork the next step is to
configure the burst command. Optional burst communication
mode allows a single slave pressure transmiiter to continuously
broadcast a standard HART reply message at a certain,
defined, configured interval.
The operation can be done in in several ways:
— Wired
— Wireless
— Local display (HMI)
The device can be configured to send up to three bust
messages with interval between 2s and 60 minutes.
The configuarable message are the following HART commands
HART command Description
Command #1 Read Primary Variable
Command #2 Read P.V. Current and Percentage of Range
Command #3 Read Dynamic Variables and P.V. Current
Command #9 Read Device Variables with Status
Command #33 Read Device Variables
Command #48 Read Additional Transmitter Status
The burst mode can be set to trigger in differnet way
— Continuous: the burst message is published continuously
at the minimum update period.
— Window: the burst message is triggered when the source
value deviates more than the specific trigger value.
— Rising: the burst message is triggered when the source
value rises above the specified trigger value.
— Falling: the burst message is triggered when the source
value falls below the specified trigger value.
— On-change: the burst message is triggered when any
value in the message changes.
The message is normally sent at the configured update period.
Once the configured trigger conditions are sotisfied, the period
is set at the configured maximum update rate.
Important.
For security reasons the join key cannot be read
back from the device as well as via the local LCD display.
Check the completion of the joinig operation with the used
pc-tool or looking at the HMI. The operation in completed once
the antenna simbol in the right top corner is fixed
Important.
To switch the HMI press for more than 2 second
the “Z” (zero) button. To reach the “Z” button, release the fixing
screw of the identification plate on the top of the instrument
housing.

7 Commissioning
7.7. 2 Burst s t a t u s
The device supports up to three Burst communications. Each
burst can be individually configured and enabled (ON) or
disabled (OFF). Depending on its configuration, each Burst
communication can have different possible Status that could be
helpful for detecting and evaluating possible critical or
anomalous situations between the gateway and the wireless
devices. If read from the wireless devices, some Burst Status
could give information about the wrong configuration of the
gateway and/or the wireless device installed. Burst status is
readible via HMI (if installed) or via dedicated section of the DTM
(see Commissioning by DTM).
“S” = Shutdown
the associated burst is in the shutdown phase. The
network manager is deleting all the resources
previously reserved at this burst. Until the burst is in
this condition, it cannot be reconfigured.
“A” = Active
the associated burst is Active/running,In this condition
the associated Burst is transmitting the selected
HART command or status to the Gateway according
to the update period.
The Bursts will be OK only when X-Y are displayed with
“A” - “A” or “A” - “O”.
When the selected “Burst Trigger” is set to “Continuous” there
is only one channel to be negotiated with the Network Manager
and in this case the second letter is not relevant (value fixed to
“O” - OFF). When the selected “Burst Trigger” is set to any
other event (Window, Rising, Falling or On-change), there are
two channels to be negotiated with the Network manager i.e.
one for the selected trigger event and the second for the
Maximum Update Period in case the trigger event never
occurs. In this case the X-Y represents the two channels. The
three bursts are displayed cyclically with an interval of 10
seconds.
Figure 33: Burst visualization into DTM
Burst status have the following structure:
“Bn: X-Y” where:
— Bn is the Burst number as B1, B2 or B3
— X-Y represent two possible channels in negotiation with
the Network Manager (Gateway) for each Burst. These
letters can assume different values:
“O” = OFF
the associated burst has not been enabled.
If the device has joined the network bursts can be
enabled wirelessly, through wired DTM or using an
handheld terminal. In case the device has not yet
joined, burst enabling can be done through the wires
of the HART protocol or exploiting the DD file
(handheld terminal)
“N” = Negotiating phase
the associated burst is in the negotiation phase with
network manager (gateway) that is reserving the
correct resources bandwidth, timings, etc.
“R” = Reject
the associated burst setting has been refused by the
network manager due to some possible conflicts i.e:
bandwidth limitation or requested burst update period
too short. In case this value appears, review the
update period.

7 Commissioning
7.9 Commissioning by DTM
The 266WiPressure DTM gives access to all parameters and
information relevant to communication and device
commissioning. Once the device is taken into the wireless
network by the gateway the DTM can be used with the wired
but also with the wireless interface, depending of the
capabilities of FDT frame application and gateway.
Typically the connection to the gateway is via Ethernet. This
allows a remote access to the wireless HART network and the
266 WiPressure over intranet or Ethernet, depending on the
network policies. Components and tools provided or
recommended by ABB do not have limitation regarding the
communication interface.
Usually the network ID and join key needs to be set to allow a
wireless device to enter an existing network. The join key and
the network ID are also set in the gateway and must be the
same as that entered in the 266 WiPressure.
The following description assumes the device needs a change
of network parameters to join a network.
The DTM will have to be connected via a wired interface to the
266 WiPressure. After searching for the device and getting into
online mode the dialog Network Settings should be opened:
The data on the bottom of the dialog gives status information
about the process of network join. Whenever a wireless HART
network is in the range of 266 WiPressure – even it does not
match its own network parameters - the “Wireless signal
found” flag is set. This is a pre-condition to join a network. The
266 WiPressure now tries to join the network and to establish a
connection to the wireless HART gateway.
A successful join phase is indicated by the “Join complete” flag
at the end. Depending of the network structure, size and
performance of wireless HART gateway and other devices in
the network it may take up to 60 minutes.
Important.
Some gateways need to switch on the “Active
Advertising” in order to support devices to join the network.
7.9.1 Network Diagnostics by DTM
One of the strengths of wireless HART networks is the
capability to automatically build a robust meshed structure. So
the wireless devices try to connect to neighbours in order to
get multiple paths for any telegram.
Powerful network diagnostics of 266 WiPressure automatically
checks the network transmission quality to and from the device
itself.DTM gives visibility about signal strenght for at maximum
five neighbour devices showing their specific link.
Signal strength is returned as a computed value which includes
signal level, retries required etc.
Figure 35: Burst B2 in OFF-OFF status
The sequence of the adjustments is as the position of the
parameters with the DTM dialog:
1. Network ID to be set in decimal notation within the DTM.
2. Join key to be set in hexadecimal notation
3. Join mode. Usually the option “Join now” is most suitable
to let the device enter the (new) network after download all
parameters described above.
Important.
In a proper and robust network, each wireless
device should have at least three neighbours.

Important. Every of the configurable parameters here on the left can
easily be modified either via the optional LCD HMI, with an 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.
8.3 Configuration types
Pressure transmitters can be configured as follows:
8.4 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 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:
To change the transmitter ranging apply the pressure for the
“lower range value” and “upper range value” to the measuring
equipment. Make sure that the measuring limits are not
exceeded.
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.
Important. In case of the 266 transmitter for absolute pressure
(266Nx) with a measuring range less than or equal 650 mbar abs.,
please be aware that the measuring equipment will have been
overloaded by the atmospheric pressure due to the long periods of
transport and storage involved. For this reason, you will need to
allow a starting time of approx. 30 minutes for 266Nx model, until
the sensor has stabilized to such an extent that the specified
accuracy can be maintained.
8.5 LRV and URV configuration
— Apply the pressure for the “lower range value” and wait
approx. 30 s until it has stabilized.
— Press the “Z” button to wake the instrument up and then
keep “Z” button pressed in order to assign the LRV.
— Apply the pressure for the “upper range value” and wait
approx. 30 s until it has stabilized.
— Press the “S” button to assign the URV.
— Record the new settings. The respective parameter will be
stored in the non-volatile memory 10 seconds after the “Z”
or “S” buttons are last pressed.
Important. This configuration procedure does not affect the
physical process pressure (PV value) also shown on the digital
display or user interface. To avoid potential discrepancies, you can
use follow the procedure below. After performing a correction, you
must check the device configuration.
— via Zero and Span push buttons (LRV and URV).
— using the integral LCD HMI with keypad (menu-controlled)
— with a handheld terminal
— using a PC/laptop via the graphical user interface (DTM)

8.9 Transfer function
The 266 Pressure Transmitter provides a selection of output
functions, as follows:
— Linear for differential, gauge and absolute pressure or level
measurements
— Sq. Root (x) for flow measurements using restriction type
primary element, like orifice plate, integral orifice, Venturi or
Dall tube and similar.
— Sq. Root (x3) for open channel flow measurements using
rectangular or trapezoidal weir
— Sq. Root (x5) for open channel flow measurements using
V-notch (triangular) weir.
— Bidirectional Flow
— Custom linearization table
— Cylindrical lying tank
— Spherical tank
These output functions can be activated using a Configuration
Tool (Digital LCD Integral Display, Hand Held Communicator or
PC based software as Asset Vision Basic).
8.12.1 Linea r
Using this function, the relationship between the input
(measured value), expressed in % of the calibrated span and
the output is linear (i.e.: at 0% input, corresponds 0% output).
8.9.2 Square root
Using the Square Root function, the output (in % of the span) is
proportional to the square root of the input signal in percentage
of the calibrated span.
The possibility to have the full Square Root function is given.
To avoid the extremely high gain error with the input approaching
zero, the transmitter output is linear with the input up with a
slope of 1 up to 0.5% and then still linear with the appropriated
slope to a programmable percentage value between 10 % and
20%. This option is offer in order to ensure a more stable output
when the signal is close to zero avoiding errors due to the high
gain of the square root.
To neglect the values with the input approaching zero, the
transmitter output is zero with the input up to a programmable
percentage value between 0 % and 20%. This option is offer in
order to ensure a more stable flow measure. This option is
possible for all the listed output functions. ).
No further settings are possible here.

8 Operation
8.9.3 Square root to the 3rd power
The x3 Square root Transfer function can be used for open
channel (see figures on the right) flow measurement using ISO
1438 rectangular weirs (Hamilton Smith, Kindsvater-Carter,
Rehbock formulas) or trapezoidal weirs (Cippoletti formulas) and
ISO 1438 Venturi flumes. In these types of devices the relationship
between the flow and the developed head h (the differential
pressure measured by the transmitter) is proportional to h3/2 or
square root of h3.
Other types of Venturi or Parshall flume do not follow this
relationship. Using this function, the output is proportional to the
square root of the third power of the input signal in % of the
calibrated span: the instrument gives an output proportional to the
rate of flow calculated using the above mentioned formulas.
8.9.5 Custom linearization curve
The custom linearization curve transfer function it is used
typically for volumetric level measurement in tanks with an
irregular shape. It can be registered to a freely identifiable
transfer function with a maximum of 22 base points. The first
point is always the zero point, the last is always the final value.
Neither of these points can be altered.
A maximum of 20 points can be freely entered in between.
These points have to be defined by extrapolating the tank filling
table data and reducing them to 22 points.Once identified the
22 points they will need to be uploaded into the device by
either using an HART hand held terminal or a proper
configuration software like Asset Vision Basic.
8.9.6 Bidirectional Flow (to be used when the transmitter
is connected to a bidirectional flow element)
The bidirectional function, applied to the transmitter input (x)
expressed in percentage of the calibrated span, has the
following form:
Output = ½ + ½ sign (x) ∙ x ½
where “x” and “Output” should be normalized in the range 0 to
1 for calculation purpose, with the following Output meaning:
— Output = 0
Figure 40: Tanks (respectively rectangula weir, trapezoidal weir and
V-notch weir)
8.9.4 Square root to the 5th power
The x5 Square root Transfer function can be used for open
channel flow measurement using ISO 1438 Vnotch (triangular)
weirs (see figure on the right) where the relationship between
the flow and the developed head h (the differential pressure
measured by the transmitter) is proportional to h5/2 or square
root of h5.
— Output = 1
This function can be used for flow measurement purpose when
the flow is in both the directions and the primary elements are
designed to perform this type of measure.
As an example, if we have a bidirectional flow measurement
application with the following data:
Max reverse flow rate: -100 l/h
Max flow rate: +100 l/h
The differential pressure generated by the flow primary is for the
maximum flow rate 2500 mmH2O, for the max reverse flow rate
2500 mmH2O.
The transmitter will have to be configured as follows:
Calibrated span: LRV = -2500mmH2O
URV = +2500mmH2O
Transfer function: Bidirectional flow
Using this function, the output (in % of the span) is proportional
to the square root of the fifth power of the input signal in % of
the calibrated span: the instrument (it gives an output
proportional to the rate of flow calculated using the KingsvaterShen formula).

8.9.7 Cylindric lying tank
This function is used to measure the volumetric level into a
cylindrical horizontal tank with flat ends.
The transmitter calculates the volume from the measured filling
level.
8.9.8 Spherical Tank
This function is used to measure the volumetric level into a
spherical tank.
The transmitter calculates the volume from the measured filling
level.
8.10 Configuration with the PC/laptop or handheld
terminal
A graphical user interface (DTM) is required for configuration of
the transmitter via PC or laptop. For operating instructions,
please refer to the software description.
The 266 transmitters can be configured by either one of the
following device.
— Hand Held terminals like the ABB DHH805, Emerson
Process 375 and 475 provided the 266 EDD has been
downloaded and enabled in the terminal.
— ABB Asset Vision Basic, a new free of charge software
configurator downloadable at www.abb.com/
Instrumentation
— Any DTM based software for HART instruments
configuration provided it is compatible with EDD or DTM.
You can use a handheld terminal to read out or configure/
calibrate the transmitter.
For additional information, refer to the operating instructions
included with the handheld terminal.
If, however, you wish to make changes to the configuration, a
handheld terminal or - preferably - a graphical user interface
(DTM) is required. This DTM tool renders the device fully
configurable. It supports the HART protocol and and can be
run on a PC or laptop, or as part of an automation system.
Refer to the installation manual provided with the software for
the steps required to install the operating tool. The most
important parameters can be set via the path “Parametrize_
Differential Pressure Measurement”.
The program offers the option of configuring, polling, and
testing the transmitter.
In addition, offline configuration can be performed by means of
an internal database.
Each configuration step is subject to a plausibility check. You
can call up context-sensitive help at any time by pressing the
“F1” key. Immediately after you have received the transmitter or
before you change the configuration, we recommend that you
save the existing configuration data to a separate data storage
medium, via the path “File_Save”.
8.11 Configuration with the graphical user interface
(DTM) - System requirements
— Operating control program (e.g., ABB Asset Vision Basic
version 1.00.17 or higher)
— DTM (Device Type Manager; graphical user interface)
— Operating system (depending on the respective control
program)
To operate the Asset Vision Basic please refer to the relevant
operating instruction.
If the transmitter has been configured in the factory according
to customer specifications for the measuring point, all you have
to do is mount the transmitter as prescribed (to correct
potential zero shifts, refer to the section “Correcting the zero
shift”), and switch it on. The measuring point will now be ready
for use.

9.1 Overview
This section provides troubleshooting suggestions for the most
common problems occuring in the field.
Important.
Procedures described in the following paragraphs
will help the user to verify that 266 pressure transmitter and
wireless communication network are correctly in place.
9.2 Device-related issues
9.2.1 Device does not power on
When the user receives a 266 WirelessHART pressure
transmitter, the first step to be taken is to power the device on.
After removing the battery pull-tab grabbing it firmly and pulling
the cell will give power supply to the electronic module LCD
display will go live for 30 seconds and then it will go off.
If this doesn’t happen the possible cause could be:
Possible cause Solution
Battery discharged
Display or battery not well
connected
Terminal block defect Check battery and terminal blocks contacts
In case the device is not powering, please check if the battery
is still in good conditions and it has not been exposed to high
temperatures for long periods of time. To install a new battery,
please follow below instructions
1. Install 266 WirelessHART pressure transmitter properly,
according to ABB practices explained in the present
document using an approved thread sealant on all
connections.
2. Unscrew the battery cover from the wireless device.
Battery lays on the opposite side of the display (if installed)
as indicated by the writing “Field Terminals” engraved on
housing neck.
3. Remove and replace the battery paying attention to the
polarity.
Change the battery (spare part number
DR3051)
Check HMI contacts or invert battery position
into the terminal block
9.3 Network-related issues
9.3.1 General
Network joining could represent a critical point for a wireless
transmitter.
Basic preliminary setting for joining consists in writing two
parameters both into the device and into the Gateway. These
parameters are:
— Network ID
— Join Key
Important.
same both on field instrument and Gateway.
It is also necessary to write the LONG TAG for communication
via Ethernet TCP/IP within the Asset Vision Basic projects.
The above-mentioned parameters can be set using:
— Asset Vision Basic wired to device dedicated terminals
through a HART modem.
— Hand-held terminal wired to device dedicated terminals
— Local HMI menu
9.3.2 Device does not join the network
After the basic settings have been correctly executed, a typical
anomalous situation is that the device does not join to the
wireless network.
Network is joined when the radio signal icon
visible on the upper right-hand corner of the HMI (if installed).
Possible cause Solution
Power supply is missing
Anyway, device will more likely not join the network due to a
radio signal failure. Radio failure can be identified thanks to the
above-mentioned icon.
Network ID and Join Key are to be always the
is steady
Access the “Z” button and depress it for few
seconds until the display goes live. If this will
not happen, see section 9.2.1
Note. Wireless devices should be powered up only during the
network setup and beginning with the closest device to the
Gateway. This will result in a simpler and faster network installation.
For further information about the battery, please refer to paragraph
6.6 of this document.
4. Close the housing cover so as to have a metal-to-metal
contact but do not over tighten. If the installation of the
battery as been properly performed, the LCD display will
go live for 30 seconds and then it will go off.
Important. Battery part number is DR3051. To get spares batteries,
please get in touch with your local ABB service reference.
Replacements with non-ABB batteries is forbidden and will lead to
certification invalidity.

10 Maintenance
10 Maintenance
If transmitters are used as intended under normal operating
conditions, no maintenance is required. It is sufficient to check
the output signal at regular intervals (in accordance with the
operating conditions), as described in the instructions in the
section “Operation resp. Configuration of the transmitter”. If
deposits are expected to accumulate, the measuring
equipment should be cleaned on a regular basis, in accordance
with the operating conditions. Cleaning should ideally be
carried out in a workshop.
Repair and maintenance activities may only be performed by
authorized customer service personnel.
When replacing or repairing individual components, original
spare parts must be used.
Attention – Potential damage to parts. The electronic
components of the printed circuit board can be damaged by static
electricity (observe ESD guidelines). Make sure that the static
electricity in your body is discharged when touching electronic
components. If a remote seal is mounted on the measuring
equipment, it must not be removed (please refer to the dedicated
document).
Warning – <Bodily injury>. Transmitter for hazardous classified
location must be either repaired by the manufacturer or approved
by a certified expert following repair work Observe the relevant
safety precautions before, during and after repair work. Only
disassemble the transmitter to the extent necessary for cleaning,
inspection, repairs, and replacement of damaged components.
10.1 Returns and removal
Defective transmitters sent to the repairs department must,
wherever possible, be accompanied by your own description of
the fault and its underlying cause.
Warning – General risks. Before removing or disassembling the
device, check for hazardous process conditions such as pressure
on the device, high temperatures, aggressive or toxic media, and
so on. Read the instructions in the sections “Safety” and “Electrical
connection”, and perform the steps outlined there in reverse order.
10.2 Pressure transmitter sensor
Essentially maintenance is not required for the transmitter
sensor. Anyway the following items should be checked
periodically:
— Check the integrity of the pressure boundary (no cracks
should be visible on the process connection or on the
process flanges.
In case one of the check points above fails, please replace the
damaged part with an original spare part.
Please contact your local ABB office for spare parts support
information or refer to the spare part list.
The use of non original spare parts makes the warranty void. In
case you want ABB to perform the repair, please send back the
transmitter to your local ABB office complete with the return
form that you find in this manual appendix and include it with
the device.
10.3 Removing/Installing the process flanges
1. Slacken the process flange screws by working on each in
a crosswise manner (hexagon head, SW 17 mm (0.67inch)
for 266DS.
2. Carefully remove the process flange, making sure that the
isolating diaphragms are not damaged in the process.
3. Use a soft brush and a suitable solvent to clean the
isolating diaphragms and - if necessary - the process
flange.
4. Insert the new process flange O-rings in the process
flange.
5. Attach the process flange to the measuring cell.
The surfaces of both process flanges must be at the same level
and at a right angle to the electronics housing (with the
exception of vertical process flanges).
6. Check that the process flange screw thread can move
freely: Manually turn the nut until it reaches the screw
head. If this is not possible, use new screws and nuts.
7. Lubricate the screw thread and seats of the screw
connection.
8. While performing the preliminary and final tightening of the
bolts, please act in a crosswise manner.
Attention – Potential damage to parts. Do not use sharp or
pointed tools.
Do not damage the insolating diaphragms.
Important. In the case of oil and grease-free designs, clean the
measuring chambers again if necessary once the process flange
has been installed.
— Check that there is no leakage from the sensor/flange
interface or from the vent/drain valves.
— The process flanges bolts (for 266DSH) should not show
excessive rust.
