7.2 Product description

The 266Jxx/266Cxx multivariable pressure transmitters measure the mass flow of gases, vapors, and liquids in accordance with the differential pressure procedure and the level of the liquids in the process industry. These transmitters supply an analog or digital output signal. Simultaneously and with high accuracy they measure differential pressure, static pressure and with a Pt100 in 4conductor technology, they also measure the process temperature. The differential pressure measuring ranges are scaled from 1 to 2000 kPa. The measuring ranges for static pressure are 0.6 to 2, 10 and 41 MPa. The transmitters can be overloaded on one side to the respective upper measuring range value of the static pressure.

7.3 Measuring range limits and span limits

The data sheets for the Series 2600T multivariable transmitters contain all the information concerning the measuring range and measuring span of the individual models, as well as the sensor code.

The following terminology is used for the different parameters:

URL: Upper Range Limit of a specific sensor. The highest

measured value t hat c an be measured by the transmitt er.

LRL: Lower Range Limit of a specific sensor. The lowest

measured value t hat c an be measured by the transmitt er.

URV: Upper Range Value The highest meas ured v alue to

which the transmitt er is cal ibrat ed.

LRV: Lower Range Value. The lowest measured value t o whic h

the transmitt er is c ali brated.

SPAN: Measuring span. The algebrai c diff erenc e bet ween t he

start of the meas uring range and t he end of the measuring range. The s mal lest span is the s malles t v alue that can be s elected wit hout i mpai ring t he s pec ified

measuring acc urac y. TURN DOWN RATIO:

Span ratio The ration between t he maxim um s pan and

the calibrat ed span.

The measuring transmitter can be calibrated to any measuring range between LRL and URL with the following restrictions. — LRL ≤ LRV ≤ (URL - CAL SPAN) — CAL SPAN ≥ MIN SPAN — URV ≤ URL

8 Mounting

Before installing the transmitter, check whether the device design meets the requirements of the measuring point from a measurement technology and safety specifications point of view. This applies in respect of the: — Measuring range — Overload resistance — Temperature — Explosion protection — 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, separating diaphragm, etc.

8.1 IP rating

The housing of pressure transmitters of the R266 series satisfies the requirements of IP degree of protection IP 66 / IP 67 (NEMA 4X) in accordance with IEC 60529. The first digit indicates the protection of the integrated electronics against penetration of foreign objects, including dust. The digit “6” means that the housing is dust tight (i.e. dust cannot penetrate). The second digit indicates the protection of the integrated electronics against the penetration of water. The digit “6” means that the housing is watertight and can even withstand a strong water jet under the specified conditions. The digit “7” means that the housing is watertight and can be temporarily immersed at a specified pressure and for a specific time, without water penetrating.

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 transmitter and, if applicable, the associated impulse line(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 (NOTICE) If unfavorable ambient conditions cannot be avoided for reasons relating to building structure, measurement technology, or other issues, the measurement quality may be affected. (See "Specifications" chapter).

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.

8.2 Factory settings

The transmitter is factory configured according to the customer’s order specifications.

IMPORTANT (NOTICE) Under normal conditions no additional settings are required.

The typical configuration includes: — Number of the measuring point tag — Calibrated span — Configuration of the flow or liquid level calculation — Configuration of the LCD display

8.3 Venting / draining transmitters without diaphragm seals

Fig. 4 1 Valve on t he proces s axis | 2 Flange side v alve on t op |

3 Flange s ide v alve on t he bott om

For transmitters without diaphragm sealers the following instructions on venting and draining must be complied with. It is important to attach the transmitter in such a manner and to layout the process line in such a manner that gas bubbles in liquid measurements can be routed back into the process and not get in to the measuring chambers.

The optional vent / drain valves on the transmitter are attached on the measuring cell flanges. Align the transmitter so that these vent / drain valves are arranged above the tap points for liquid measurement, so that gas can escape upward. For gas measurements align the transmitter so that the vent / drain valves are arranged below the tap points, so that air or condensate can drain.

8.4 Mounting position

The transmitter can be attached directly on a valve manifold provided for flange installation. Optionally a fastening bracket for wall or pipe installation (2” pipe) is available as an accessory. For models 266CRx and 266JRx fastening brackets must always be used. Ideally the transmitter must be mounted in such a manner that the separating diaphragms are standing vertical, to avoid later zero point offsets.

IMPORTANT (NOTICE) If the transmitters are mounted with an inclination that is not vertical, the filling fluid exerts hydrostatic pressure on the measuring diaphragm, which causes a zero point offset. In this case the zero point can be adjusted via the zero point button or with the command “Install position correction”. See chapter “Configuration”.

DANGER - severe health impairments / lifethreatening danger due to escaping measurement medium! During the venting or draining process medium that is being discharged can escape and endanger personnel who are not working in the vicinity. Consequently when venting or draining, any escaping process medium must be collected.

8.7 Rotating the transmitter housing

To improve access to electrical connections and for better visibility of the optional LCD display in the field, the transmitter housing can be rotated through 360°. A stop prevents the housing from being turned too far. In order to rotate the housing, the fixing screw must be loosened and unscrewed approx. one revolution (do not remove it). As soon as the desired position is reached, the fixing screw will be retightened.

8.8 Rotating the integral LCD display

If the device has an integral LCD display, this can be mounted in four different positions, each of which can be rotated through 90°. To rotate the LCD display, open the windowed cover (ensuring compliance with special requirements for hazardous areas) and pull the LCD display out of the electronics module. Reposition the LCD display connector accordingly. Plug the LCD display back into the electronics module, checking that the 4 plastic fixing locks are securely in place.

Fig. 17 : Rotat ing the LCD di splay

8.9 Connecting impulse lines

In order for the impulse lines to be laid correctly, the following points must be observed: — The impulse lines must be as short as possible and have

no sharp bends

— Lay the impulse lines so that no deposits can

accumulate in them. Gradients should not be less than approx. 8 % (ascending or descending)

— The impulse lines should be blown through with

compressed air or, better still, flushed through with the medium prior to connection

— With wet legs, the liquid in both lines must be at the

same level

— With vaporous measuring media, measures must be

taken to prevent steam entering the measuring chambers of the measuring cell and causing overheating

— It may be necessary to use condensate vessels or

similar with small measuring spans and vaporous media

— If you are using condensate vessels (steam

measurement), you should ensure that the vessels are at the same elevation in the differential pressure piping

— As far as possible, keep both impulse lines at the same

temperature

— Completely depressurize the impulse lines if the medium

is a liqu id

— Lay the impulse lines so that gas bubbles (when

measuring liquids) or condensate (when measuring gases) can flow back into the process line

— Ensure that the impulse lines are connected correctly

(connection of high-pressure and low-pressure sides to

the measuring cell, seals, etc.) — All connections must be secure and tight — Lay the impulse lines so that the medium cannot be

blown out over the measuring cell

WARNING – bo dily injury! Leaks in the process lines can result in death or severe injuries. Install and seal process connections and all accessory elements (including valve blocks) before the charging the device with pressure. For applications with toxic or hazardous substances prior to venting or draining, take all precautionary measures that are recommended in the respective safety data sheet. Only tighten the screws of the fastening accessories with a size 12 mm (15/32”) inch hexagon socket wrench.

8.10 Process connections

Fig. 18

On the flange of the 266 multivariable transmitter there are 1/4 – 18 NPT process connections with middle point spacings of 54 mm (2.13 in.). The process connections on the flange enable direct attachment of 3 element or 5 element valve manifolds. Optionally flange adapters with 1/2 – 14 NPT connections are available. By turning one or both adapters, middle point spacing of 51 mm (2.01 in.), 54 mm (2.13 in.) or 57 mm (2.24 in.) is possible.

Mount the adapters as follows:

1. Correctly position the adapters with inserted O-ring.

2. Screw the adapters on the transmitter connection flange with the provided screws.

Tighten the scr ews as follows: Preliminary tightening

hand tight, preliminary tightening with 10 Nm, final tightening with 50 Nm.

8.11 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. — The lengths of the protective tubes should be

15 ... 20 times the diameter of the protective tube for gas

measurements and 3 ... 5 times the diameter of the

protective tube for liquid measurements.

8.12 Mounting recommendations

The arrangement of the impulse lines depends on the respective measurement application.

Fig. 19 : St eam f low measurement A High-press ure v alve | B Low press ure v alve | C Equaliz ing v alve | H High pres s ure s ide | L Low pres s ure side

Place taps to the side of the process line. For liquid measurements, mount the transmitter next to or underneath the taps, for steam measurements underneath the taps. Mount the vent / drain valve pointing upward. For steam applications, fill the vertical section of the impulse lines with a compatible fluid through the appropriate filling connections. The height of the liquid column between process line and transmitter must be the same on the high pressure side and the low pressure side, so that an accurate measurement is ensured. For implementation of this requirement it can be practical for steam measurements, to use the impulse lines condensate tanks. To commission the transmitter, operate the valves in the following sequence:

1. Open the equalizing valve (C)

2. Close the low pressure valve (B) and high pressure valve (A).

3. Open the primary shutoff valves

4. Slowly open the high pressure valve (A) so that the measuring medium can flow into the measuring cell on both sides.

5. Vent or drain the measuring cell and close the valves.

6. Open the low pressure valve (B) and close the equalizing valve (C).

9 Electrical connections

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.

NOTICE - material damage due to electrostatic discharge! An open cover does not provide contact protection. Touching conductive parts can damage electronic components (in some cases beyond repair) due to electrostatic discharge. Therefore, do not touch conductive components.

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 galvanic 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.

DANGER – explosion hazard! If the type of protection specified on the certification plate does not agree with the requirements imposed on the implementation site, explosions or fires can be triggered. In this case the transmitter must NOT be connected electrically.

DANGER - severe health impairments / lifethreatening danger! The lines can carry dangerous touch voltages and cause electric shocks. An electric shock can be fatal or can cause serious injuries. Consequently do not touch the conductors and connection terminals.

Change from tw o to one col umn

9.1 Cable connections

The electric connection is made using a 1/2-14 NPT or M20 x 1.5 cable entry. Basically, a metal cable gland should be provided for th Pt100 cable, since a shielded cable will be used. Connect the shielding within the metal cable gland! To ensure an 4X and IP 66-67 IP rating for the transmitter, the cable gland must be screwed into the housing (1/2" NPT female thread) using a suitable sealing compound.

IMPORTANT (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.

IMPORTANT (NOTICE) For the purpose of simulation, a 178 Ω resistor (206°C / 402.8°F) with 2 jumpers has been installed between the terminals for the Pt100 connection. This resistor (including the jumpers in the case of 4-wire connections) must be removed before connecting the Pt100. If a Pt100 is not connected, the resistor must not be moved.

IMPORTANT (NOTICE) For category 3 transmitters for use in “Zone 2” a type of protection approved for this cable gland must be provided by the customer (see chapter “Ex-relevant technical data”). An appropriate thread M20 x 1.5 must be provided in the electronics housing for this purpose. for transmitters with “Ex d”, Flameproof Enclosure” the housing cover must be arrested with the securing screw. The screw plug possible provided with the transmitter must be inserted on site with the sealant, Molykote DX. If a different sealant is used, the responsibility rests with the executing installer. At this point we expressly state that after several weeks the housing cover can only be unscrewed with an increased expenditure of force. This is not caused by the threads, but instead is due solely to the type of seal.

9.2 Connection of the analog output (HART)

Change from one to two col umns

For connection of signal voltage / supply voltage twisted cable with a conductor cross section of 18 … 22 AWG /

0.8 … 0.35 mm2 to2 to max. 1500 m length must be used.

Avoid cable installation, together with other power lines (with inductive load, etc.), as well as the vicinity to large electrical

installations. For longer leads a greater cable cross section is required. For shielded cables the cable shielding must only be placed on one side (not on both sides). For the grounding on the transmitter the inner terminal marked with can also be used. The output signal (4 ... 20 mA) and the power supply are conducted via the same conductor pair. The transmitter always works with a supply voltage between 10.5 and 42 V DC.

The HART handheld terminal can be connected to any

connection point in the circuit if a resistance of at least

250 Ω is present in the circuit. If there is resistance less than

250 Ohm an additional resistor must be provided to enable

communication. The handheld terminal is connected

between the resistor and transmitter, not between the

resistor and the power supply. For devices with “Ex ia” type of protection, “Intrinsic Safety” (FM, CSA, and SAA approval) the supply voltage must not exceed 30 V DC. In some countries the maximum supply voltage is limited to lower values. The permissible supply voltage is specified on the name plate on the top of the transmitter. The possible line length depends on the total capacity and the total resistance and can be estimated based on the following formula.

9.4 Wiring

Proceed as follows to wire the transmitter: — Unscrew the transport screw plug from one of the two

cable entries located on both sides in the upper part of the transmitter housing

— These cable entries have a 1/2 inch NPT or M20x1.5

female thread. Various adapters and bushings can be fitted to these threads to comply with plant wiring (conduit) standards

DANGER - Risk to life due to explosion! In an explosion-proof / flameproof installation in a hazardous area, the housing cover of the terminal compartment must not be removed when the voltage is connected, as an explosion may be caused by spark formation. Before removing the housing cover of the terminal compartment, disconnect the equipment from the supply voltage and take suitable measures to prevent reconnection.

— Remove the housing cover from the terminal

compartment.

— Run the connection cable through the opening and

connect the + wire to the + terminal and the - wire to the – terminal.

— Run the temperature sensor cable (if there is one)

through the second cable entry and connect it to the designated terminals

IMPORTANT (NOTICE) Do not connect the supply voltage across the test terminals. It could damage the test diode in the test connection.

— Replace the housing cover on the terminal compartment

and tighten it by hand until the cover contacts the housing metal-to-metal. To prevent the housing cover from turning, in "Ex-d” type of protection (flameproof enclosure) installations, lock it by turning the locking screw / hex-head screw anti-clockwise with the 2 mm Allen key supplied with the device.

1 Cover safety screw Fig. 26

WARNING – bo dily injury! If the cables, cable glands and stopper plugs used for the electrical connection do not satisfy the requirements for the type of protection (e.g. intrinsic safety, flameproof enclosure, etc.) and the necessary degree of protection for the housing (e.g. IP 6x in accordance with IEC EN 60529 or NEMA 4x), explosions or fires can be triggered. For this reason, the red plastic transport caps must be replaced with cable glands or stopper plugs, that are approved for the required type of protection and the required degree of protection for the housing. See section “Ex-relevant technical data”.

9.5 Protective conductor connection / grounding

For the ground (PE) of the transmitter or the connection of a protective conductor, a connection is available on the exterior of the housing, and also in the terminal compartment. Both connections must be galvanically connected to one another. These connection points can be used if grounding or the connection of a protective conductor is prescribed by national regulations for the selected type of supply or the type of protection used.

— Plug and seal the cable entries. Make sure that when the

installation has been completed, these openings are properly sealed to prevent the entry of rain and corrosive vapors and gases. In particular, for "Ex-d" (flameproof enclosure) installations, plug unused openings with a suited sealing plug that has been certified for explosion protection.

— If applicable, install the connection cable with a drip

loop. Arrange the drip loop so the lower part is located below the cable entry and the transmitter housing

10 Commissioning

10.1 G eneral remarks

Once the pressure transmitter has been installed, it is put into operation by switching on the operating voltage. Prior to switching on the operating voltage check: — Process connections — Electrical connection — Complete filling of the impulse line and measuring

chamber of the measuring cell with the measuring medium.

The transmitter can then be put into operation. To do this, the valves must be actuated in the following order (in home position, all valves are closed):

1. Open the shut-off valves on the pressure tap connection

(if present).

2. Open the pressure equalization valve of the valve block.

3. Open the shut-off valve of the high pressure side (H) on

the valve block.

4. Open the shut-off valve on the low pressure side (L) on

the valve manifold.

5. Close the pressure equalization valve.

Decommissioning is executed in the reverse sequence.

If, when using transmitters with type of protection "intrinsic safety", an ammeter is connected to the output circuit or a modem is connected in parallel while there is a risk of explosion, the sums of the capacitances and inductances of all circuits, including the transmitter (see EC-typeexamination certificate) must be equal to or less than the permissible capacitances and inductances of the intrinsically safe signal circuit (see EC-type-examination certificate for the power supply unit). Only passive or explosion-proof test devices or display instruments may be connected.

10.2 O utput signal

If the applied pressure is within the values indicated on the

rating plate, the output current ranges between 4 and 20 mA.

If the pressure applied falls outside the set range, the output

current will be between 3.5 mA and 4 mA if the range is

underranged or between 20 mA and 22 mA if the range is

overrranged (depending on the respective configuration).

Standard setting for normal operation

3.8 mA / 20.5 mA

A current that is < 4 mA or > 20 mA may also indicate that

the microprocessor has detected an internal error.

Standard setting for error detection

21.8 mA

In this case diagnosis of the error can be executed with the

aid of different configuration tools.

IMPORTANT (NOTICE) A brief interruption in the power supply results in initialization of the electronics (program restarts).

10.3 Zero point correction following installation

Once the transmitter has been installed, it is advisable to

check the zero point and correct it if necessary.

If the output signal stabilizes only slowly, it is likely that a large damping time constant has been set on the transmitter.

10.3.1 Setting precalibrated devices

(The lower range value has already been set to 0.) 266Cxx transmitters do not support this function if the "Level measurement" calculation function has been activated. In this case, the correction must be made using the optional LCD indicator, the handheld terminal, or the DTM.

IMPORTANT (NOTICE) For this purpose, the DIP switch on the electronics board must be set to position 1.

A PV Bias / Offset correction can be performed via the local push buttons as follows: — Separate the transmitter from the process and equalize

the pressure in the two measuring chambers by

adjusting the bypass valve in the manifold. — Check the transmitter output signal If it is at 4 mA (or PV = 0), zero point correction is not

required.

I f t he output is not at zero, proceed as follows: — Unscrew the screws attaching the name plate to the top

of the transmitter housing — Rotate the name plate so that the push buttons can be

accessed — Check that the write protection rotary switch is set to

write enable — Press and hold down the zero button (Z) on the top of

the transmitter for at least 3 seconds The output signal switches to 4 mA and the message

“OPER DONE” appears on the LCD display (if there is

one). — If nothing happens, check the write protection rotary

switch. It is probably set to write protection. — For all other diagnosis notices, refer to the instructions — As soon as zero point correction is complete, reconnect

the transmitter to the process — Open the pressure equalization valve on the manifold. — Open the shut-off valve of high-pressure side — Open the pressure equalization valve on the manifold. — Open the shut-off valve on the low-pressure side

10.3.2 Zero-point increase/suppression on precalibrated devices

(e.g., 4 ... 20 mA = -100 ... 100 mbar) This function is only supported by 266Jxx and 266Cxx transmitters if the calculation function has been disabled.

IMPORTANT (NOTICE) For this purpose, the DIP switch on the electronics board must be set to position 0.

— Isolate the transmitter from the process and vent the

transmitter measuring chamber(s) to atmosphere — Apply the lower range value pressure (4 mA). The pr essure must be stable and applied with a high

level of accuracy (< 0.05 %, observing the set damping

value) — Check the transmitter output signal If it is at 4 mA (or PV = 0), zero point correction of the

transmitter is not required. I f t he output is not at zero, proceed as follows: — Unscrew the screws attaching the name plate to the top

of the transmitter housing — Rotate the name plate so that the push buttons can be

accessed — Check that the write protection rotary switch is set to

write enable. — Press and hold down the zero button (Z) on the top of

the transmitter for at least 3 seconds The output signal switches to 4 mA and the message

“OPER DONE” appears on the LCD display (if there is

one) — If nothing happens, check the write protection rotary

switch. It is probably set to write protection. — For all other diagnosis notices, refer to the instructions — As soon as zero point correction is complete, reconnect

IMPORTANT (NOTICE) After the transmitter has been adjusted as described above, the zero bias / offset value is activated and stored in the memory of the transmitter. In this case calibration of the transmitter is can no longer be executed. Only if the PV bias / offset value is reset, will a sensor calibration be possible again.

11 Configuration

The transmitter is delivered preconfigured according to the information provided when placing the order. However, should a change to the configuration be necessary (because measuring point data has changed since the original plans were drawn up, for example), the following options are available: — Local keypad for the LRV / URV setting (266Jxx only)

and zero point correction following installation

— Menu-led configuration of the transmitter with the

integrated LCD indicator — Configuration using a handheld terminal — Configuration using a PC / laptop with graphical user

interface (DTM) How to use these tools to make the configuration settings is described in the corresponding related documentation.

11.1 Wr ite protection

The write protection prevents unauthorized users from overwriting the configuration data. With activated write protection the operating buttons "0% (Z)" and "100 % (S)" have no function. A change of parameters with the integral LCD indicator, via a handheld terminal, or the user interface (DTM) are not possible either. However the configuration data can be read out via the graphic user interface (DTM) or a comparable communication tool. If needed the operating device can also be sealed with a lead seal.

Write protection can be activated as follows (see also the symbols on the plate).

1. Use a suitable screwdriver to press the switch all the

way down.

2. Turn the switch 90° clockwise.

11.2 Hardware settings

Fig. 30: DIP switches (example, HART version)

There are six DIP switches on the secondary electronics. They are used to make settings if an LCD display is not present. DIP switches 1 and 2 activate REPLACE MODE for the sensor and the secondary electronics (NEW SENSOR / NEW ELECTRONIC). DIP switch 3 specifies the functions of the external pushbuttons (Z/S) PUSHBUTTON MODE). Zero corrections / span corrections or PV offset (bias) / PV offset (bias) reset. DIP switches 4 and 5 are use to select the alarm current (high / low).

IMPORTANT (NOTICE) Always disconnect the device from the power supply before making changes to DIP switches. The device must then be restarted in order for the new configurations to be loaded.

IMPORTANT (NOTICE) To deactivate write protection, press the switch down slightly and then turn it counterclockwise 90°.

Page 35

Replace mode (DIP switches 1 and 2) In normal mode the DIP switches 1 and 2 are in position 0. If a replacement procedure is necessary, they will be activated. When replacing the electronics or the sensor, disconnect the power supply and move DIP switch 1 to position 1. When replacing the secondary electronics, disconnect the power supply and move DIP switch 2 to position 0. The sensor can be replaced when DIP switch 2 is in position 1.

IMPORTANT (NOTICE) We recommend resetting the corresponding DIP switch to position 0 after each replace operation.

Push buttons mode (DIP switch 3) DIP switch 3 is factory-set to position 1. This means that the the zero pushbutton (Z) sets the PV offset (bias) value (bias = current digital measured value) to 0 and the span push button resets the PV offset (bias) value set to 0 with (Z). If this DIP switch is on position 0, the zero button (Z) and the span button (S) are used for setting the start of the measuring range (zero) and measuring voltage (span). For this the appropriate pressure for the values to be set must be specified.

11.3 Fact ory settings

The transmitters calibrated in the factory to the measuring range specified by the customer. The calibrated measuring range and the measuring point tag are specified on an additional labeling plate. If nothing is specified by the customer in this regard, the transmitter will be delivered with a standard configuration, that contains the following parameters (among others).

Each of the parameters listed here can be easily set via the optional LCD display with operating menu, a HART handheld terminal or a compatible software solution.

IMPORTANT (NOTICE) For 266Cxx transmitters, we recommend leaving DIP switch 3 in position 1 at all times.

Fail mode (DIP switches 4 and 5) Users wishing to modify the factory-set parameters for the alarm current (in the event of a transmitter failure) must set DIP switch 4 to position 1. Consequently, users must select whether the output is to change to the minimum or maximum output current. DIP switch 5: — The output is high in position 0 (> 20 mA to 22 mA; please specify exactly) — The output is low in position 1 (< 4 mA to 3.7 mA; please specify exactly)

11.4 Configuration of the transmitter without integrated LCD display

IMPORTANT (NOTICE) The configuration possibilities described below are only possible for the models 266Cxx with switched off rake function and for the 266Jxx models.

The parameters “start of measuring range” and “Span” are set directly on the transmitter via the operating buttons. These operating buttons are arranged under the rating plate///. In order to operate the device locally, unscrew the fastening screws of the rating plate, and swing the rating plate clockwise to the side.

11.4.1 Configuration of LRV and URV (4 … 20 mA range)

1. Measuring range start pressure (4 mA) - specified by the process or by a pressure generator. Pressure must be stable and must be applied with high accuracy < 0.05%. Press operating button “Z”. The output current is set to 4 mA.

2. Charge the transmitter with the pressure that corresponds to the end of the measuring range, and wait for approx. 30 seconds, until it has stabilized.

3. Press the operating button “S”. The output current is set itself to 20 mA.

4. If required, reset the damping back to the original value.

5. Document the new values that have been set. The appropriate parameters will be saved 10 seconds after the last activation of the operating button “Z” or “S” in non-volatile memory.

ATTENTION – material damage due to a magnetic field! The use of magnetic screwdrivers results in damage of components. Do not use a magnetic screwdriver to operate the buttons.

The transmitter has been calibrated by the manufacturer based on the order information. The set measuring range start and measuring/// range end are specified on the identification plate.

The following always applies: — The first pressure value (e.g. 0 mbar) is always assigned

to the 4 mA signal (or 0%) and the second pressure value (e.g. 400 mbar) is always assigned to the 20 mA signal (or 100%).

— To make new settings on the transmitter “measuring

range start” and measuring range end” are specified on the measuring cell as pressure. In this regard, measuring range limits must not be exceeded.

IMPORTANT (NOTICE) A reducing station with adjustable pressure and reference display can be used as the pressure generator.

IMPORTANT (NOTICE) This configuration procedure only changes the 4 … 20 mA current signal; the process value shown on the digital display or the user interface remain unchanged in this process. Possible differences can be avoided as described. After such a correction, the device configuration must be checked.

For the connection, ensure that liquid residues (for gaseous test materials) or air bubbles (for liquid test materials) are not in the impulse line; liquid residue can cause measurement errors in the test. The possible measuring error for the pressure generator should be at least three times less than the desired measuring error for the transmitter. It is required to set the damping to the value “zero”.

Notice regarding menu “Process Alarm” In this menu the behavior of the analog output current (current limits) for measuring range overshoots and alarm states can be configured. As long as the process value moves within the already set span, the output signal is between 4 and 20 mA. If the process value (PV) underranges the lower range value (LRV), the signal will be set to the configurable lower current limit; if the process value exceeds the measuring range end URV), the signal will likewise be set to the configurable upper current limit. If the diagnostic function of the transmitter detects an error, the signal will be set to high alarm or low alarm, depending on the user-defined setting. The parameter “Fail Safe Level” (Fail Mode) can be adjusted via the DIP switches 4 and 5 of the electronics module. The precise value that the signal assumes can be set via the “Process Alarm” menu. In this process the limit for the low alarm current must be below the lower current limit and the limit for the high alarm current must be above the upper current limit.

11.6 Configuration with the PC / laptop or handheld terminal

The 266 multivariable transmitters can be configured with the aid of the following devices: — Handheld terminals such as the ABB DHH800 MFC, or

from a different manufacturer, with the prerequisite that the 266 EDD has been loaded and activated in the terminal.

— ABB Asset Vision Basic, a free-of-charge software

configurator, that can be downloaded at www.abb.com/Instrumentation.

— Software for configuration of field devices, with the

prerequisite that it is compatible with EDD or DTM.

A handheld terminal can be connected directly to a 4 ... 20 mA line if the connected power supply unit is equipped with an integrated communication resistor. If a communication resistor with a resistance of at least 250 Ω is not present, an additional resistor must be installed. Connect the handheld terminal between the resistor and the transmitter, not between the resistor and the power supply unit.

For additional information, see the “Handheld Terminal” operating instruction.

When using a graphic user interface (DTM) all configuration possibilities are available. The procedure for program installation is described in the appropriate installation manual delivered with the software. The transmitter can be configured, read out and tested via the program. With the aid of the integrated database a configuration can also be executed in offline mode. Each configuration step is subject to a plausibility check. A each point of the program context-sensitive help can be called via “F1”. Immediately after receipt of the transmitter or after changing the configuration, we recommend that back up the existing configuration on a separate data medium under “Save in database”.

Operating instructions for the program “Asset Vision Basic” are provided in the appropriate user manual.

11.7 Damping and transmission function

11.7.1 Damping

If the output signal of the pressure transmitter is conditionally irregular due to the process it can be electrically smoothed (damped). The additional time constant can be set in increments of

0.0001 seconds to a value between 0 and 60 seconds. The damping has no influence whatsoever on the digitally displayed measured value in the physical unit. It only acts on the values that are derived from this, such as the analog output current, the free process variable, the input signal for the controller, etc. The damping can be set locally via the LCD operating interface (HMI), via the “Asset Vision Basic” software, or via a handheld terminal.

11.7.2 Transmission function

In the evaluation of the output signal of the mulitvariable transmitters, you must bear in mind that these devices can work with different transmission functions.

For the 266Jxx the following can be set: — Linear for measurements of differential pressure or fill

level

— Square root (x) for flow measurements in accordance

with the differential pressure procedure with throttle elements such as orifices, nozzles, Venturi / swirl tubes and similar items

— Square root (x3) for flow measurements in open chutes

with rectangular or trapezoidal measurement weir

— Square root (x5) for flow measurements in open chutes

with V-measurement weir (triangular weir)

— Bidirectional for flow measurements with bidirectional

characteristic curve — With customer-specific linearization table. — For cylindrical, horizontal tanks — For spherical tanks

These transmission functions can also be set for the 266Cxx models, if the rake function is switched off.

For 266Cxx multivariable transmitters, set for mass flow measurement, the following functions are possible: — Square root (x) for differential pressure flow measuring

with throttle elements — Bidirectional for flow measurements with bidirectional

characteristic curve

In addition, all characteristic curves are influenced by the pressure-dependent and temperature-dependent status correction.

For 266Cxx multivariable transmitters set for level measurement, the following functions are possible: — Linear — With customer-specific linearization table — For cylindrical, horizontal tanks — For spherical tanks

Moreover, all characteristic curves are influenced by the temperature-dependent, for drum water level measurement, also pressure-dependent, density correction.

The output transmission functions can be activated via a configuration tool (integral digital LCD display, handheld terminal or PC software such as “Asset Vision Basic”).

Description of the transition function

Linear When using this function the relationship between the input value (measured value) in % of the calibrated measurement span and the output linear (i.e.: The input value of 0% corresponds to an output value of 0% = 4 mA, the input value of 100% corresponds to an output value of 100% = 20 mA). Additional settings are not possible here.

Square root With this function the output (in % of the measuring span) is proportional to the square root in % of the set measuring span (i.e.: The device outputs an analog output signal that behaves proportionally to the flow rate). It is possible to use the complete square root function.

For leak flow volume suppression for small input signals close to the zero point the transmitter output is set to zero until reaching an adjustable activation point between 0% and 20%. This function ensures the stability for flow measurements. The default setting is 6% of the upper range value of the flow.

Fig. 41 1 Square root f uncti on | 2 Activat ion pont l eak f low v olum e suppres s ion, programm able

Fig. 39

In order to avoid the high gains occurring in the vicinity of the zero point, the transmitter works linear with a gradient of 1 to an input value of 0.5% of the set measuring span, and then continues linear to the activation point of the square root function, adjustable between 5% and 20% of the output. This function enables a more stable output signal close to the zero point and avoids errors due to the high gain associated with the square root. The standard setting is 5% of the upper range value of the flow.

Square root to the third power

The square root transmission function of x3 can be used for flow measurements in open chutes (see Fig. 42 and Fig. 43) with rectangular measuring weirs or trapezoidal measuring weirs, as well as Venturi flumes in accordance with ISO

1438. For these devices the relationship between flow and dammed up height h (differential pressure measured by the transmitter) is proportional to h3/2 or to the square root of h3. For other Venturi flumes or Parshall flumes this relationship is not right. For this function the output (in % of the measuring span) is proportional to the square root to the third power of the input signal in % of the set measuring span. With the aid of the formulas cited, the device provides an output signal that is proportional to the flow rate.

Square root to the fifth power

The square root transmission function of x5 can be used for flow measurements in open flumes of V measuring weirs (triangular weirs) in accordance with ISO 14398 (see Fig.

44); the relationship between flow and dammed up height h (differential pressure measured by the transmitter) is proportional to h5/2 or to the square root of h5. With this function the output in % of measuring span is proportional to the square root to the fifth power of the input signal in % of the set measuring span. The device delivers an output signal that behaves proportionally to the calculated flow rate.

Customer-specific linearizaton characteristic curve

The transmission function with a customer-specific linearization curve is normally used for volume measurement in tanks with unusual shapes. There is an assignment to a freely-definable transmission characteristic curve with a maximum of 22 reference points. The first reference point is always the zero point, the last is the upper range value. These two reference points cannot be changed. In between a maximum of 20 points can be freely entered. These max. 22 points are defined by extrapolating the tank fill data. After they are determined, the 22 reference points are loaded into the device, via a HART handheld terminal or via an appropriate configuration program such as “Asset Vision Basic”.

Example of a bidirectional flow measurement with the following data: — Max. negative flow: -100 t/h — Max. positive flow: +100 t/h

The differential pressure generated by the primary element of the flow meter is 2500 mm H2O for the max. positive flow and 2500 mm H2O for the max. negative flow.

Thus the transmitter must be configured as follows:

Set meas uring s pan:

4 mA = LRV = -2500 mm H2O 20 mA = URV = 2500 mm H2O Transmission f uncti on = Bidirectional

Flow measurement with bidirectional characteristic curve

This method is used if the transmitter is connected to a bidirectional flow meter (e.g. a wedge meter - wedge-shaped narrowing). The main characteristics: The bidirectional transmission function acts an the transmitter input (x) as a percentage value of the calibrated measuring span and is calculated with the following formula:

Output = 1/2 + 1/2 sign (x) ∙ x 1/2

In this regard x and the output signal of the transmitter are scaled in the range from 0 to 1 for the calculation. The output has the following meaning: — Output = 0 = analog output signal 4 mA; — Output = 1 = analog output signal 20 mA;

This function can be used for bidirectional flow rates, for which the primary device is configured for this application.

Change from tw o to one col umn

After the transmitter has been configured as described above, it supplies the following for:

Negative f low of 100 t/h: Output signal = 4 mA No flow: Output signal = 12 mA Positive fl ow of 100 t/h: Output signal = 20 mA

Cylindrical horizontal tank

This function is used for the volume measurement in cylindrical horizontal tanks with straight ends. The transmitter calculates the volume and / or the mass from the measured fill level.

Spherical tank

This function is used for volume measurement in spherical tanks. The transmitter calculates the volume and / or the mass from the measured fill level.

14 Maintenance / Repair

14.1 Dismount ing

WARNING – Bod ily injury The device can be operated at high pressure and with aggressive media. Any medium that squirts out can cause severe injuries. Depressurize the pipeline/tank before opening the transmitter connection.

NOTICE – 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 before touching electronic components.

If pressure transmitters are used as intended under normal operating conditions, no maintenance is required. It suffices if the measuring range start and/or the spat are checked at specific intervals - depending on the operating conditions. If deposits are expected to accumulate in the measuring cell, the measuring cell should be cleaned on a regular basis, in accordance with the operating conditions. Preferably the measuring cell should be cleaned in a workshop.

WARNING – Potential danger if device is disassembled incorrectly! 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. Carefully read the instructions in the sections “Safety", "Mounting", and “Electrical connections”, and perform the specified steps in reverse order.

14.2 Safeguard the housing cover for devices with “Ex d” type of protection

After tasks on the transmitter housing, for devices with “Ex d” type of protection strictly ensure that the housing cover is safeguarded again. To do this, a safety screw (hexagon socket screw) is provided on both facing sides of the electronics housing, at the bottom.

1. Screw the housing cover hand tight onto housing.

2. Turn the safety screw counterclockwise to secure the

cover. The screw is unscrewed until the screw head arrests the housing cover.

IMPORTANT (NOTICE) For transmitters in safety-relevant applications in accordance with IEC 61508, verification in accordance with the paragraph “Acceptance test” in chapter “Functional safety in accordance with IEC 61508” is prescribed at fixed time intervals.

Repair and maintenance tasks must only be executed by employees of an authorized customer service organization. For replacement and repair of individual components use original parts.

WARNING – bo dily injury! Transmitters with explosion protection must be either repaired by the manufacturer or approved by a certified expert after the repair. Comply with the relevant safety regulations and take the appropriate safety precautions before, during, and after repair work.
