1.4 Matching of Communicator DD and Instrument DD

CAUTIONBefore using the 275 HART Communicator, make that the device description(DD) installed in the communicator matches that of the instrument that is being set up. To check the DD of the instrument and the HART communicator, follow the steps below. If the correct DD is not installed in the communicator, you must upgrade the DD at an authorized facility. For communication tools other than the 275 HART Communicator, contact the vendor for upgrade information.

1. Checking the DD of the instrument1) Connect the communicator to the instrument

that is being set up.

2) Call Device setupandpress[→].

3) Call Reviewandpress[→].

<2. Conditions of Communication Line> 2-1

IM 01C25T01-01E

2. Conditions of Communication LineThe HART communication signal is superimposed onto the 4 to 20 mA DC analog signal. Since the modulated wave is a communication signal, superimposing it on the normal signal will, from basic principles, cause no error in the DC component of the analog signal. Thus, monitoring can be performed via the 275 HART Communicator while the transmitter is on-line.

2.1 Interconnection Between DPharp and the HART Communicator

The HART communicator can interface with the transmitter from the control room, the transmitter site, or any other wiring termination point in the loop, providedthereisaminimumof250Ωbetweentheconnection and the power supply. To communicate, it must be connected in parallel with the transmitter; the connections are non-polarized. Figure 2.1 illustrates the wiring connections for direct interface at the transmitter site for the DPharp. The HART communicator can be used for remote access from any terminal strip as well.

• The measurement span is determined by the upper and lower range values. Changing the lower range value causes the upper range value to change automatically, keeping the span constant. If a change in the lower range value causes the upper range value to exceed the measuring limit of the transmitter, an error message appears and the transmitter holds the output signal right before the error occurred. Enter the correct values within the range of the sensor limits.

• Note that changing the upper range value does not cause the lower range value to change. Thus, changing the upper range value also changes the span.

3.5.7 Sensor TrimEach DPharp EJX series transmitter is factory characterized. Factory characterization is the process of comparing a known pressure input with the output of each transmitter sensor module over the entire pressure and temperature operating range. During the characterization process, this comparison information is stored in the transmitter EEPROM. In operation, the transmitter uses this factory-stored curve to produce a process variable output (PV), in engineering units, dependent on the pressure input.

The sensor trim procedure allows you to adjust for local conditions, changing how the transmitter calculates process variables. There are two ways to trim the sensor: a zero trim and a full sensor trim. A zero trim is a one-point adjustment typically used to compensate for mounting position effects or zero shifts caused by static pressure. A full sensor trim is a two-point process, in which two accurate end-point pressures are applied (equal to or greater than the range values), and all output is linearized between them.

(1) Zero Trim

a. Zeroing—Pres Zero trim

Pres Zero trim carries out the zero adjustment and automatically sets the applied “0” input values to the output value of “0,” keeping the span constant. Use this setting when the LRV is known to be 0 mmH2O.

c. UsingExternalZero-adjustmentScrew

This method permits zero adjustment without the HART communicator. Use a slotted screwdriver to turn the zero-adjustment screw. See the hardware manual for details.

Note that the parameter of Ext SW must be Enabled to perform this adjustment. See section 3.5.11 for the setting procedure.

(2) Full Sensor Trim—Auto Trim and Manual Trim

Full sensor trim is carried out with a series of the procedure of Auto, Lower Pt and Auto, Upper Pt. Also, you can manually perform the trimming procedure in Manual, Lower Pt and Manual, Upper Pt.

The full sensor trim is a two-point adjustment, and the lower point adjustment should always be performed before the upper point adjustment in order to maintain the pitch between the zero and 100% points within the calibration range.

In the manual method, the reference pressure should also be applied to the transmitter at both lower and upper point of trim ends. Without the reference pressure, P LTD and P UTD may not represent the correct value of adjustment point for each.

4.1.1 IdentifyProblemsbyUsingtheCommunicator

The HART communicator can be used to run self-diagnostics on a transmitter and check for incorrect data settings.

The Self test and Status commands are available for self-diagnostics. When Self test is run, the integral indicator shows an error code and alarm message if the transmitter detects any illegal parameter settings and functional faults. See table 4.3.1 Alarm Message Summary for probable causesandcountermeasures.Ifthespecificdiagnostic item is known for the check, you can directly call up the item by using the Status command. See table 4.3.1 to determine the status group.

The HART communicator diagnoses every command you make. When a faulty command or keypad input is performed, an error message appears. See table 4.3.2 HART Commnicator Error Messages for the details.

4.2 Advanced Diagnostics

4.2.1 Multi-sensing Process MonitoringMulti-sensing process monitoring function (option code: /DG6) provides the advanced diagnostics to detect the abnormal conditions in process environment such as an impulse line etc. by using the EJX multisensing technology and its unique algorithm. There are following two functions.

Impulse Line Blockage Detection (ILBD)

Thefluctuationchangeofdifferentialpressureandstatic pressure is monitored by a silicone resonant sensor and detects a potential blockage condition. The differential pressure transmitter gives also a result of which pressure-side was plugged.

Heat Trace Monitoring

The two temperature sensors built in the EJX calculatetheflangetemperature,thechangeofwhich enables to detect the heat trace breakage or the abnormal temperature due to the failure.

4.2.2 Impulse Line Blockage Detection (ILBD)

ILBD is carried out by using statistical analysis based on the measured values of process fluctuationsthatexistinafluid.AnalarmontheEJX LCD display or an analog alert is generated if blockage reaches a certain level. EJX provides the following results as blockage detection.(1) A Blocking and B Blocking

These are blockage detections based on thefluctuationvaluechangeofdifferentialpressure/pressure. With a differential pressure transmitter, each result indicates that both or single side is plugged.

(2) L Side BlockingIt is a low-pressure side blockage detection based on the change of BlkF or low-pressure-sidefluctuationvalue.

(3) H Side BlockingIt is a high-pressure side blockage detection based on the change of BlkF or high-pressure-sidefluctuation

*: BlkF indicates blockage degree characterized by a comparison of the high- and low-pressure-sidefluctuationvalues.Forthedetails,refertoFigure 4.2.2.

IMPORTANT• Thepressurefluctuationamplitudeinfluidsmustbesufficientlylargeforblockagestobedetected.

• Ifthepressurefluctuationamplitudeistoolow for a reference value to be obtained, blockages detection operation cannot be performed with an alarm that the reference value is invalid.

• Thepressurefluctuationamplitudemaydecrease due to other causes unrelated with a blockage according to process condition. In above case, a false alarm of an impulse line blockage may be generated. Before taking action in response to a blockage alarm, consider the plant operating conditions.

Notes for Pressure or Level Measurement

With pressure or level measurement, the pressure fluctuationamplitudemayreduceespeciallyforthefollowing cases.

Pressure Measurement• Operational pressure is near outside of

diagnostic range.• Eventhoughpressureisconstant,theflow

decreases than that under normal condition.• Asourceofpressurefluctuation(pump,

compressor, blower, etc.) is shut down. As aresult,thepressurefluctuationamplitudedecreases.

Level Measurement

• A transmitter is used to measure tank level and theflowoffluidintooroutofthetankcomestoa stop.

• The agitator in the tank is shut down.• A source of pressure variation (a compressor,

etc.) that controls the internal pressure of a sealed (closed) tank is shut down.

Before taking action in response to a blockage alarm, consider the plant operating conditions.

A/BBlockingDetection“A Blocking” and “B Blocking” indicates the result estimated from blockage degree based on the difference of the high- and low-pressure-side fluctuation values. RatiofDP, SQRT (fDP/ReffDP) is used to detect A/B blocking. ReffDP is the average value of the sum of squares of differential pressure fluctuations under normal condition.

As the value of RatiofDP exceeds the value of LimfDPmax, EJX gives basically an alarm of “A Blocking”. On the other hand, if this value is below the value of LimfDPmin, EJX gives an alarm of “B Blocking.

As a high- or low-pressure-side blockage progresses, fDP increases. Therefore, “A Blocking” with a differential pressure transmitter indicates that a single-side impulse line is plugged for a differential pressure transmitter. As the both-side blockages progress simultaneously, fDP decreases. Therefore, “B Blocking” with a differential pressure transmitter indicates that both-side impulse lines are plugged.

NOTEA single-side impulse line blockage may generate “B blocking” under the condition where the fluctuation amplitude is much different between high- and low-pressure sides.

With a transmitter to measure pressure or tank level, “B blocking” only is detected.

H/LBlockingDetectionEJX differential pressure transmitter enables to detect both-, a high-, or low-pressure-side blockage. The blockage degree characterized by a comparison of high-pressure side and low-pressure-side fluctuation values, BlkF, is used to detect it. The value changes within a range of –1 to +1. As BlkF approaches +1, the high-pressure-side blockage progresses. On the other hand, if it approaches –1, the low-pressure-side blockage progresses.

Figure4.2.2 RelationbetweenBlockageProgressandBlkF

The each threshold value to detect the high- or low-pressure-side blockage is set to LimBlkFmax or LimBlkFmin.

LSideBlockingDetectionBlkF is preferentially used to "L Side Blocking" detection. If BlkF cannot be used, RatiofSPl, SQRT (fSPl/ReffSPl) is used to "L Side Blocking" detection. ReffSPl is the average value of the sum of squares of low-pressure-side static pressure fluctuations under normal condition.

As the value of RatiofSPl is below the value of LimfSPlmin, EJX gives an alarm of "L Side Blocking".

On the other hand, if this value exceeds the value of LimfSPlmax, EJX gives an alarm of “Large Fluct L”.

HSideBlockingDetectionBlkF is preferentially used to "H Side Blocking" detection. If BlkF cannot be used, RatiofSPh, SQRT (fSPh/ReffSPh) is used to "H Side Blocking" detection. ReffSPh is the average value of the sum of squares of high-pressure-side static pressure fluctuations under normal condition.

As the value of RatiofSPh is below the value of LimfSPhmin, EJX gives an alarm of "H Side Blocking".

On the other hand, if this value exceeds the value of LimfSPhmax, EJX gives an alarm of “Large Fluct H”.

LargeFluctuationDetectionWhen a pump or compressor starts, the large fluctuation is generated as process condition changes rapidly. This phenomenon affects process fluctuation measurement; so correct blockage detection is not performed.


IM 01C25T01-01E

If “Large Fluct L” or “Large Fluct H” is detected, consider whether a blockage result is correct.

Thethresholdvaluestodetectlargefluctuationareset to Lim fSPlmax and Lim fSPhmax.

Since these values are enough to detect large fluctuation,itisnotalmostnecessarytochangethem.

4.2.2.2 CombinationofReferenceResultand Blockage Detection

An EJX differential pressure transmitter can detect four modes of impulse line blockage: both-sides, high-pressure side, low-pressure side, and/or single-side when all the reference values are properly measured. However, the detectable alarm mode combination is limited when some of the reference values are invalid. Available Blockage Detectionareshowninthebelowfigure.

IMPORTANT• If the impulse line is about to be plugged at

the time when a reference value is obtained, blockages cannot be detected accurately. The impulse lines on both the high-pressure and low-pressure sides need to be cleaned before a reference value is obtained.

• All air bubbles need to be adequately purged before a reference value is obtained.

• Reference values must be obtained under operating condition.

Start of SamplingThe sampling of reference value is carried out for 180 sec, which is the default value set to Diag Period.

1) Confirmthatthesamplingperiod(Diag Period) is set to 180 sec.

2) Set “Reference” to Diag Mode. The sampling starts soon after the setting.

IMPORTANT• For the each parameter, the one value is

given. If Reference is set to Diag Mode again, the value is updated and overwritten.

• If the power supply is shut down during the sampling, Diag Mode becomes “Stop”. Set “Reference” to Diag Mode in order to carry out the sampling again.

End of SamplingAfter about 180 sec, the sampling automatically finishes.The“Reference”settingofDiag Mode moves automatically to “Calculation”.

ConfirmthatthesettingofDiag Mode moves to “Calculation”.

4.2.2.8 CapabilityTestofBlockageDetection Operation

Before performing the ILBD operation, check the capability of the blockage detection operation. The simulation test is performed by closing motion of a three-valve manifold or stop valve. When simulatedblockageoccurs,confirmthatanalarmisgenerated.

NOTE• Thefluctuationamplitudeofatmospheric

pressure is nearly zero with pressure or level measurement. In such case, simulate the blockage detection by closing the valve wherethefluctuationexisted.


Simulation of High-pressure Side Blockage1) Close the high-pressure-side valve.2)ConfirmthevalueofPres is stable. If not,

open the valve a little.3) Set “Calculation” to Diag Mode so as to start

blockage detection operation.4) Check that an alarm of “H Side Blocking” is

generated after the time that consists of Diag Period and Diag Supp Count passed.

5) Check also the operation of the analog alert if an analog alert is set.

6) Open the valve completely and check that there are no alarms.

If process condition and capability to detect a blockageareconfirmed,youcanstarttheILBDoperation according to the following procedure.

1) Check the value of sampling period (Diag Period).

2) Check the number of times that detect the blockage consecutively in order to give an alarm (Diag Supp Count). The default value at the shipment is set to 3 times.

3) Set “Calculation” to Diag Mode. If the reference value has not yet been

obtained, set “Reference” to Diag Mode. After obtained the reference values, the ILBD starts automatically. At the same time, Diag Mode changes automatically from “Reference” to “Calculation”.

4.2.2.10 Tuning


Whenthepressurefluctuationamplitudeinfluidsisnotsufficientlylargeoranalarmisoftengeneratedaccording to the process condition, tune up by changing the threshold for the blockage detection (Limit parameters) or the sampling period (Diag Period) to enhance the accuracy of the blockage detection The ILBD operation must be stopped to tune up.

IM 01C25T01-01E

Appendix 1. Safety Instrumented Systems Installation

WARNING

The contents of this appendix are cited from exida.com safety manual on the EJX series pressuretransmittersspecificallyobservedforthe safety transmitter purpose. When using the EJX for Safety Instrumented Systems (SIS) application, the instructions and procedures in this section must be strictly followed in order to preserve the transmitter for that safety level.

A1.1 Scope and PurposeThis section provides an overview of the user responsibilities for installation and operation of the EJX in order to maintain the designed safety level for Safety Instrumented Systems (SIS) applications. Items that will be addressed are proof testing, repair and replacement of the transmitter, reliability data, lifetime, environmental and application limits, and parameter settings.

A1.2 Using the EJX for an SIS Application

A1.2.1 Safety AccuracyTheEJXhasaspecifiedsafetyaccuracyof2%.This means that the internal component failures are listed in the device failure rate if they will cause an error of 2% or greater.

A1.2.2 Diagnostic Response TimeThe EJX will report an internal failure within 5 seconds of the fault occurrence.

A1.2.3 SetupDuring installation the transmitter must be setup with engineering units parameters. This is typically done with a handheld terminal. These parameters mustbeverifiedduringtheinstallationtoinsurethat the correct parameters are in the transmitter. Engineeringrangeparameterscanbeverifiedbyreading these parameters from the optional local display or by checking actual calibration of the transmitter.

The calibration of the transmitter must be performed after parameters are set.

A1.2.4 Required Parameter SettingsThe following parameters need to be set in order to maintain the designed safety integrity.

TableA1.2.4 RequiredParameterSettings

Item DescriptionBurnout direction switch

The output shall go 21.6 mA or higher or 3.6 mA or lower upon detection of an internal failure.

Write protection switch

The write function shall be disabled.

A1.2.5 Proof TestingThe objective of proof testing is to detect failures within the transmitter that are not detected by the diagnostics of the transmitter. Of main concern are undetected failures that prevent the safety instrumented function from performing its intended function. See table A1.2.5 for proof testing method.

The frequency of the proof tests (or the proof test interval) is to be determined in the reliability calculations for the safety instrumented functions for which the EJX is applied. The actual proof tests must be performed more frequently or as frequently asspecifiedinthecalculationinordertomaintainrequired safety integrity of the safety instrumented function.

Thefollowingtestsneedtobespecificallyexecutedwhen a proof test is performed. The results of the proof test need to be documented and this documentation shall be part of a plant safety management system. Failures that are detected shall be reported to Yokogawa.

The personnel performing the proof test of the transmitter shall be trained in SIS operations including bypass procedures, EJX transmitter maintenance, and company management of change procedures.


IM 01C25T01-01E

TableA1.2.5 ProofTesting

Testing method Tools required Expected outcome RemarksFunctional test:1. Follow all Management of Change

procedures to bypass logic solvers if necessary.

2. Execute HART/BRAIN command to send value to high alarm (21.5 mA) and verify that current has reached this level.

3. Execute HART/BRAIN command to send value to low alarm (3.6 mA) and verify that current has reached this level.

4. Restore logic solvers operation and verify.

• Handheld terminal Proof Test Coverage =52%

The output needs to be monitored to assure that the transmitter communicates the correct signal.

Perform three point calibration along with the functional test listed above.

• Handheld terminal • Calibrated pressure

source

Proof Test Coverage =99%

A1.2.6 Repair and ReplacementIf repair is to be performed with the process online the EJX will need to be bypassed during the repair. The user shall setup appropriate bypass procedures.

In the unlikely event that the EJX has a failure, the failures that are detected shall be reported to Yokogawa.

When replacing the EJX, the procedure in the installation manual shall be followed.

The personnel performing the repair or replacement oftheEJXshallhaveasufficientskilllevel.

A1.2.7 Startup TimeThe EJX generates a valid signal within 1 second of power-on startup.

A1.2.8 Firmware UpdateIncasefirmwareupdatesarerequired,theywill be performed at factory. The replacement responsibilities are then in place. The user will not berequiredtoperformanyfirmwareupdates.

A1.2.9 ReliabilityDataA detailed Failure Mode, Effects, and Diagnostics Analysis (FMEDA) report is available from Yokogawa with all failure rates and failure modes.

TheEJXiscertifieduptoSIL2foruseinasimplex(1oo1)configuration,dependingonthePFDavgcalculation of the entire Safety Instrumented Function.

ThedevelopmentprocessoftheEJXiscertifiedupto SIL3, allowing redundant use of the transmitter up to this Safety Integrity Level, depending the PFDavg calculation of the entire Safety Instrumented Function.

When using the transmitter in a redundant configuration,theuseofacommoncausefactor(β-factor)of2%issuggested.(However,iftheredundant transmitters share an impulse line or if clogging of the separate impulse lines is likely, a common cause factor of 10% is suggested.)

Note that the failure rates of the impulse lines need to be accounted for in the PFDavg calculation.

A1.2.10 Lifetime LimitsThe expected lifetime of the EJX is 50 years. The reliability data listed the FMEDA report is only valid for this period. The failure rates of the EJX may increase sometime after this period. Reliability calculations based on the data listed in the FMEDA report for EJX lifetimes beyond 50 years may yield results that are too optimistic, i.e. the calculated Safety Integrity Level will not be achieved.

A1.2.11 Environmental LimitsTheenvironmentallimitsoftheEJXarespecifiedinthe user’s manual IM 01C25.

A1.2.12 Application LimitsTheapplicationlimitsoftheEJXarespecifiedintheuser’s manual IM 01C25. If the transmitter is used outside of the application limits, the reliability data listed in A1.2.9 becomes invalid.

A1.3.1 DefinitionsSafety Freedom from unacceptable

risk of harm

Functional Safety The ability of a system to carry out the actions necessary to achieve or to maintain a definedsafestatefortheequipment/machinery/plant/apparatus under control of the system

Basic Safety The equipment must be designed and manufactured such that it protects against risk of damage to persons by electrical shock and other hazards and against resulting fireandexplosion.Theprotection must be effective under all conditions of the nominal operation and under single fault condition

Verification Thedemonstrationforeachphase of the life-cycle that the (output) deliverables of the phase meet the objectives andrequirementsspecifiedbythe inputs to the phase. The verificationisusuallyexecutedby analysis and/or testing

Validation The demonstration that the safety-related system(s) or the combination of safety-related system(s) and external risk reduction facilities meet, in all respects, the Safety RequirementsSpecification.The validation is usually executed by testing

Safety Assessment The investigation to arrive at a judgment -based on evidence- of the safety achieved by safety-related systems
