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

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

5.6 Mounting a P style pressure transmitter (266H and 266N)
The pressure transmitter can be mounted directly on the manifold.
A mounting bracket for wall or pipe mounting (2” pipe) is also available as an accessory.
Ideally, the pressure transmitter should be mounted in a vertical position to prevent subsequent zero shifts.

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.

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.

5.13 Installation recommendations
Impulse piping configuration depends on the specific measurement application.
Important. Wireless pressure transmitters are equipped with antenna and extended rear cover. The following installation sketches are shown for convenience only. Please consider the antenna and the battery seat while planning installation schemes.
5.13.1 Steam (condensable vapor) or clean liquids flow measurement
— Place taps to the side of the line.
— Mount beside or below the taps.
— Mount the drain/vent valve upward.
— In case of steam application fill the vertical section of the connecting lines with a compatible fluid through the filling tees.
The process fluid must enter the transmitter primary:
1. Open equalizing valve (C)
2. Close low pressure (B) and high pressure (A) valves .
3. Open gate valves
5.13.2 Gas or liquid (with solids in suspension) flow measurement
— Place the taps to the top or side of the line.
— Mount the transmitter above the taps.
The process fluid must enter the transmitter primary:
1. Open equalizing valve (C)
2. Close low pressure (B) and high pressure (A) valves .
3. Open gate valves
4. Slowly open high pressure (A) valve to admit process fluid to both sides of primary.
5. Vent or drain the primary unit and then close the valves.
6. Open the (B) valve and close the equalizing valve.
4. Slowly open high pressure (A) valve to admit process fluid to both sides of primary.
5. Vent or drain the primary unit and then close the valves.
6. Open the (B) valve and close the equalizing valve.
Figure 23: Gas or liquid flow measurement (transmitter and manifold)
Caution. Manifolds can be supplied both mounted on pressure
transmitters and loose. In case of integral mounting, consider that:
— All adjustments should be carried out by qualified personnel with the valve without pressure.
— End connections must not be removed from the body.
— Do not use handle wrenches or extensions to operate the valves.
Figure 22: Steam or clean liquid flow measurement (transmitter and manifold)
22 OI/266/WIHART-EN | 2600T Series Pressure transmitters
— Head units must not be removed once installed.
— Do not cover or remove body marking.
Important. The maximum working temperature of the whole assembly (manifold and instrument) corresponds to the temperature limit of the pressure transmitter.
Important. When the manifold is assembled to a 2600T pressure transmitter with NACE compliance A4-50 Stainless Steel bolts (available on request), please note that the maximum working pressure is limited to 210 bar (3045 psi).
