2.2 UnpackingWhen moving the transmitter to the installation site,keep it in its original packaging. Then, unpack thetransmitter there to avoid damage on the way.

2.3 StorageThe following precautions must be observed whenstoring the instrument, especially for a long period.

(1) Select a storage area which meets the followingconditions:• It is not exposed to rain or water,• It suffers minimum vibration and shock,• It has an ambient temperature and relative

humidity within the following ranges:Ambient temperature:

–40 to 85°C for a transmitter without integralindicator–30 to 80°C for a transmitter with integralindicator

Relative humidity:5% to 100% R.H. (at 40°C)

IM 01C20H01-01E2-2


However, it is preferable at normal temperature andhumidity (approx. 25°C and 65% R.H.).

(2) When storing the transmitter, repack it as nearly aspossible to the way it was packed when deliveredfrom the factory.

(3) If storing a transmitter that has been used, thor-oughly clean diaphragm surfaces (the pressure-detector sections) of the diaphragm seals, so that nomeasured fluid remains on them.In addition, make sure before storing that thepressure-detector and transmitter assemblies aresecurely mounted.

2.4 Selecting the InstallationLocation

The transmitter is designed to withstand severeenvironmental conditions. However, to ensure stableand accurate operation for many years, the followingprecautions must be observed when selecting aninstallation location.

(1) Ambient TemperatureAvoid locations subject to wide temperature variationsor a significant temperature gradient. If the location isexposed to radiant heat from plant equipment, provideadequate thermal insulation and/or ventilation.

(2) Ambient AtmosphereAvoid installing the transmitter in a corrosive atmo-sphere. If the transmitter must be installed in a corro-sive atmosphere, there must be adequate ventilation aswell as measures to prevent intrusion or stagnation ofrain water in conduits.

(3) Shock and VibrationSelect an installation site suffering minimum shock andvibration (although the transmitter is designed to berelatively resistant to shock and vibration).

(4) Installation of Explosion-protected Trans-mitters

Explosion-protected transmitters can be installed inhazardous areas according to the types of gases forwhich they are certified. Important precautions regard-ing such use are included at the end of this manualunder “Installation and Operating Precautions forIntrinsically Safe Explosion-Protected Instruments” and“Installation and Operating Precautions for FlameproofExplosion-Protected Instruments.” Read these thor-oughly and carefully.

2.5 Pressure Connection

WARNING

(1) Instrument installed in the process is underpressure. Never loosen or tighten the flangebolts as it may cause dangerous spouting ofprocess fluid.

(2) If the accumulated process fluid may be toxicor otherwise harmful, take appropriate careto avoid contact with the body, or inhalationof vapors even after dismounting the instru-ment from process line for maintenance.

The following precautions must be observed in order tosafely operate the transmitter under pressure.

• Never apply a pressure higher than the specifiedmaximum working pressure.

2.6 Waterproofing of CableConduit Connections

Apply a non-hardening sealant to the threads towaterproof the transmitter cable conduit connections.(See Figure 5.4.2a, 5.4.2b, 5.4.2c and 5.4.2d.)

2.7 Restrictions on Use of RadioTransceivers

IMPORTANT

Although the transmitter has been designed toresist high frequency electrical noise, if a radiotransceiver is used near the transmitter or itsexternal wiring, the transmitter may be affectedby high frequency noise pickup. To test for sucheffects, bring the transceiver in use slowly from adistance of several meters from the transmitter,and observe the measurement loop for noiseeffects. Thereafter, always use the transceiveroutside the area affected by noise.

IM 01C20H01-01E2-3


2.8 Insulation Resistance Testand Dielectric Strength Test

Since the transmitter has undergone insulation resis-tance and dielectric strength tests at the factory beforeshipment, normally these tests are not required.However, if required, observe the following precau-tions in the test procedures.

(1) Do not perform such tests more frequently than isabsolutely necessary. Even test voltages that do notcause visible damage to the insulation may degradethe insulation and reduce safety margins.

(2) Never apply a voltage exceeding 500V DC (100VDC with an internal lightning protector) for theinsulation resistance test, nor a voltage exceeding500V AC (100V AC with an internal lightningprotector) for the dielectric strength test.

(3) Before conducting these tests, disconnect all signallines from the transmitter terminals. Perform thetests in the following procedure:

• Insulation Resistance Test(1) Short-circuit the + and – SUPPLY/BT terminals in

the terminal box.(2) Turn OFF the insulation tester. Then connect the

insulation tester plus (+) lead wire to the shortedSUPPLY/BT terminals and the minus (–) leadwireto the grounding terminal.

(3) Turn ON the insulation tester power and measurethe insulation resistance. The voltage should beapplied short as possible to verify that the insula-tion resistance is at least 20 MΩ.

(4) After completing the test and being very careful notto touch exposed conductors disconnect theinsulation tester and connect a 100 kΩ resistorbetween the grounding terminal and the short-circuiting SUPPLY/BT terminals. Leave thisresistor connected at least one second to dischargeany static potential. Do not touch the terminalswhile it is discharging.

• Dielectric Strength Test(1) Short-circuit the + and – SUPPLY/BT terminals in

the terminal box.(2) Turn OFF the dielectric strength tester. Then

connect the tester between the shorted SUPPLY/BTterminals and the grounding terminal. Be sure toconnect the grounding lead of the dielectric strengthtester to the ground terminal.

(3) Set the current limit on the dielectric strength testerto 10 mA, then turn ON the power and graduallyincrease the test voltage from ‘0’ to the specifiedvoltage.

(4) When the specified voltage is reached, hold it forone minute.

(5) After completing this test, slowly decrease thevoltage to avoid any voltage surges.

Figure 4.1 Mounting the Diaphragm Seals

IMPORTANT

Please use a gasket which has a bigger insidediameter than that of gasket facing (d) ondiaphragm seal. In case a gsket which has asmaller inside diameter than that of gasketfacing is used, it may cause an error as thegasket prevents diaphragm from workingcorrectly. (Refer to ‘Dimensions’ later in thismanual)

IMPORTANT

• When measuring the liquid level of the tank, theminimum liquid level (zero point) must be set toa level at least 50 mm above the center of thehigh pressure side diaphragm seal (see Figure4.2).

• Correctly install the diaphragm seals on thehigh and low pressure sides of the process,checking the label on each seal.

• To avoid measuring error duets temperaturedifference between the two diaphragm seals,capillaries must be bound together. The capil-laries must be securely fixed to the tank wall toprevent movement by wind or vibration. If thecapillaries are too long, loosely coil the excessand secure using suitable clamps.

• During the diaphragm seal installation, ensureas far as possible that no seal liquid head isapplied to the diaphragm seals.

• Excercise care so as not to damage diaphragmsurface. Since the diaphragm protrudes ap-proximately 1 mm from the flange surface,placing the diaphragm seals with their dia-phragm surfaces facing downward may dam-age the diaphragm surfaces.

• Do not sharply bend or twist capillaries or applyexcessive stress to them.

4.4 Affixing the Teflon FilmThe FEP Teflon option includes a Teflon film andfluorinated oil.

Before mounting the diaphragm seal to the processflange, affix the Teflon film as follows:

IMPORTANT

(1) Position the diaphragm seal so that thediaphragm is in a upward position.

(2) Pour the fluorinated oil on the diaphragm andgasket area covering it completely andevenly. Be careful not to scratch the dia-phragm or change its shape.

(3) Affix the Teflon film over the diaphragm andgasket area.

(4) Next, carefully inspect the cover and try toidentify any entrapped air between thediaphragm and the Teflon film. The air mustbe removed to ensure accuracy. If airpockets are present, use your fingers toremove the air by starting at the center of thediaphragm and work your way out.

(5) Place the gasket with the teflon film and affixto the process flange.

5.1 Wiring Precautions

IMPORTANT

1.Lay wiring as far as possible from electricalnoise sources such as large capacity trans-formers, motors, and power supplies.

2.Remove electrical connection dust cap beforewiring.

3.All threaded parts must be treated with water-proofing sealant. (A non-hardening siliconegroup sealant is recommended.)

4.To prevent noise pickup, do not pass signaland power cables through the same ducts.

5.Explosion-protected instruments must be wiredin accordance with specific requirements (and,in certain countries, legal regulations) in orderto preserve the effectiveness of their explo-sion-protected features.

Refer to the “Installation and OperatingPrecautions for TIIS Flameproof Equipment”and “Installation and Operating Precautionsfor TIIS Intrinsically Safe Equipment” at theend of this manual for correct wiring.

5.2 Selecting the Wiring Materi-als

1. Use stranded leadwires or cables which are the sameas or better than 600V grade PVC insulated wire(JIS C3307) or equivalent for wiring.

2. Use shielded wires in areas that are susceptible toelectrical noise.

3. In areas with higher or lower ambient temperatures,use wires or cables appropriate for such tempera-tures.

CAUTION

If the transmitter is flameproof and the ambienttemperature is 50°C or more, use cables havinga maximum allowable heat resistance of least75°C in consideration of the instrument’s genera-tion of heat or the cables’ self-heating.

4. In environments where oils, solvents, corrosive gasesor liquids may be present, use wires or cables thatare resistant to such substances.

5. It is recommended that crimp-on solderless terminallugs (for 4 mm screws) with insulating sleeves beused for leadwire ends.

After operating preparation is completed, adjust thezero point.

When adjusting the transmitter zero point, the liquidlevel in a tank does not have to be set to the low limit(0%) of the measuring range. In such case, match thetransmitter output signal with the actual measuredvalue using, for example, a glass gauge.

(1) When the liquid level in a tank can be setto the low limit of the measuring range(0%):

Using the transmitter zero-adjustmentscrew

Before using the zero-adjustment screw outside thetransmitter case, confirm the following.

• Parameter ‘J20: EXT ZERO ADJ’ display must be‘ENABLE’. See Subsection 7.3.2 (14) for the settingprocedure.

• If the transmitter is equipped with an integralindicator, ‘E.ZERO’ must be displayed.

Use a slotted screwdriver to turn the zero-adjustmentscrew. Turn the screw clockwise to increase the outputor counterclockwise to decrease the output, the zeropoint adjustment can be adjusted with a resolution of0.01% of the setting range.

The degree of zero adjustments varies with the screwturning speed. Therefore, turn the screw slowly for fineadjustment and quickly for coarse adjustment.

6.1.3 Starting Operation

When the operation described in Subsection 6.1.2 iscompleted, the transmitter is already in operation.Perform the following:

1. Confirm the operating status.The output signal may widely fluctuate (huntingstate) due to process pressure periodic variation.In such case, BRAIN TERMINAL operationcan dampen the transmitter output signal.Confirm the hunting state using a receivinginstrument or the integral indicator and set theoptimum damping time constant. See Subsection7.3.2 (3) “Damping time constant setup.”

2. After confirming the operating status, performthe following:

IMPORTANT

• Remove the BRAIN TERMINAL from theterminal box, and confirm that none of theterminal screws are loosened.

• Close the terminal box cover and the (amplifier)case cover. Securely screw each cover untilthey cannot be turned.

• For TIIS flameproof type, hook the shroudingclamps to the cover edge and tighten themounting screws using an Allen wrench.

• Tighten the zero-adjustment cover mountingscrew to fix the cover in position.

6.1.4 Shutting Down Operation

Turn OFF power.

NOTE

If the transmitter is to be shut down for a pro-longed period, detach the transmitter (diaphragmseals) from the tank.

6.2 Measurement Range forLiquid Level Measurement(Determination of DifferentialPressure Range)

The following describes the procedure for calculatingthe differential pressure range for liquid level measure-ment.

Parameters Required for CalculationGL: Specific gravity of liquid inside tank (assumed not

to vary during liquid level measurement)

GC: Specific gravity of capillary seal liquid (assumednot to vary during liquid level measurement)

Density of gas or steam in tank:Omitted from calculation

Conversion factor in pressure unit:1 Pa = 1.01972 × 10–1 mmH2O

7.3 Setting Parameters Using theBT200

IMPORTANT

Do not turn off the transmitter as soon as BRAINTERMINAL settings have been made. If thetransmitter is turned off less than 30 secondsafter parameters have been set, the set data willnot be stored and the terminal returns to previ-ous settings.

Table 7.3.1 Parameter Usage and Selection

7.3.1 Parameter Usage and Selection

Before describing the procedure for setting parameters,we present the following table showing how theparameters are used in what case.

Setup Item Description

Sets the integral indicator scale to a % scale or user-set engineering units scale.For engineering units scale, 4 data are set: user-set engineering scale designation unit (for BT200 display), display value at 4 mA DC, and display value at 20 mA DC.

Used mainly to stabilize output near 0% if output signal is the square root mode.Two modes are available: forcing output to 0% for input below a specific value, or changing to proportional output for input below a specific value.

Reverses the direction for 4 to 20 mA DC output relative to input.Reverse mode is used for applications in which safety requires that output be driven toward 20 mA if input is lost.

Sets a unit for static pressure displayed on the BT200.

Sets a unit for temperatures displayed on the BT200.

Sets modes for output signal and integral indicator to “Linear mode” (proportional to input differential pressure) or to “Square root mode” (proportional to flow).

Adjusts the output response speed for 4 to 20 mA DC.Can be set in 9 increments from 0.2 to 64 s.

Sets the Tag No. (using 16 alphanumeric characters).Note: Up to 8 alphanumerics (upper case

letters) can be used in the BT100.

Sets the calibration range for 4 to 20 mA DC.Sets three data items : range unit, input value at 4 mA DC (LRV), and input value at 20 mA DC (HRV).Note: LRV and HRV can be specified with

range value specifications up to 5 digits (excluding any decimal point) within the range of –32000 to 32000.

Setup Item Description

Used to measure bi-directional flows.Output at zero flow is 12 mA DC, with output range equally divided between forward and reverse flow.Can be used with square root mode.

Allows user to enter up to 5 items of any desired text in up to 8 uppercase alphanumeric characters per item.

Adjusts zero point.This can be done either using the external zero-adjustment screw on the transmitter or using the BT200.

Range for 4 to 20 mA DC signal is set with actual input applied.Sets 20 mA DC output precisely with respect to user’s reference instrument output.Note that DPharp is calibrated with high accuracy before shipment, so span should be set using the normal range setup.

Used where installation conditions make it imperative to connect high pressure side impulse line to low pressure side of transmitter. Reversal of orientation should be dealt with by reversing impulse line wherever possible. Use this function only where there is no alternative.

Displays the status of 4 to 20 mA DC output when a CPU failure. The parameter of the standard unit is fixed to the high limit value (a change to the low limit value is not possible).Specify the optional code /C1 when selection of a HIGH/LOW limit is necessary.

Bi-directional flow measurementP.7-12

Sets the status of the 4 to 20 mA DC output when an abnormal status is detected with the capsule or the amplifier as the result of self-diagnosis. One of the following statuses; last held, high limit, and low limit values, can be selected.

(15) Zero Point Adjustment (J10: ZERO ADJ,J11: ZERO DEV, J20: EXT ZERO ADJ)

The DPharp supports several adjustment methods.

Select the method best suited for conditions matchingthe state of the site.

Note that output signal can be checked by displayingparameter “A10: OUTPUT(%)” on the BT200.

Adjustment Method Description

Zero adjustment using the BT200.

Zero adjustment using the external zero-adjustment screw. P.7-14

Set the present input to 0%. P.7-14Adjust for 0% output at input level of 0%.

Adjust output to the reference value obtained using other means. P.7-14If the input level cannot easily be made 0% (because of tank level, etc.), adjust output to the reference value obtained using other means, such as a sight glass.

Adjust zero point using the zero-adjustment screw on the transmitter.This permits zero adjustment without using the BT200.Accurately adjust the output current to 4 mA DC or other target output value using an ammeter that accuratly reads output currents.

8. MAINTENANCE

8.1 Overview

WARNING

Since the accumulated process fluid may betoxic or otherwise harmful, take appropriate careto avoid contact with the body, or inhalation ofvapors during draining condensate or ventinggas in transmitter pressure-detector section andeven after dismounting the instrument from theprocess line for maintenance.

Maintenance of the transmitter is easy due to itsmodular construction. This chapter describes theprocedures for calibration, adjustment, and the disas-sembly and reassembly procedures required forcomponent replacement.

Since the transmitters are precision instruments,carefully and thoroughly read the following sectionsfor proper handling during maintenance.

IMPORTANT

• As a rule, maintenance of this transmittershould be implemented in a maintenanceservice shop where the necessary tools areprovided.

• The CPU assembly contains sensitive partsthat may be damaged by static electricity.Exercise care so as not to directly touch theelectronic parts or circuit patterns on the board,for example, by preventing static electrificationby using grounded wrist straps when handlingthe assembly.Also take precautions such as placing a re-moved CPU assembly into a bag with anantistatic coating.

8.2 Calibration Instrument Selec-tion

Table 8.2.1 shows the instruments required for calibra-tion. Select instruments that will enable the transmitterto be calibrated or adjusted to the required accuracy.

The calibration instruments should be handled carefullyso as to maintain the specified accuracy.

8.3 CalibrationUse the procedure below to check instrument operationand accuracy during periodic maintenance or trouble-shooting.

<1> Connect the instruments as shown in Figure 8.3.1and warm up the instruments for at least fiveminutes.

IMPORTANT

1. To adjust the transmitter for highest accuracy,make adjustments with the power supplyvoltage and load resistance including leadwireresistance set close to the conditions underwhich the transmitter is installed.

2. If the measurement range 0% point is 0 kPa0 mmH2O or shifted in the positive direction(suppressed zero), the positive referencepressure should be applied on the highpressure side, as shown in the figure. If themeasurement range 0% point is shifted in thenegative direction (elevated zero), the positivereference pressure should be applied on thelow pressure side.

<2> Apply reference pressures of 0%, 25%, 50%,75%, and 100% of the measurement range to thetransmitter. Calculate the errors (differencesbetween digital voltmeter readings and referencepressures) as the pressure is increased from 0% to100% and is decreased from 100% to 0%, andconfirm that the errors are within the requiredaccuracy.

INSTALLATION AND OPERATING PRECAUTIONS FOR TIIS INTRINSICALLY SAFE EQUIPMENT

INSTALLATION AND OPERATING PRECAUTIONS FORTIIS INTRINSICALLY SAFE EQUIPMENT

Apparatus Certified Under Technical Criteria (IEC-compatible Standards)and from “RECOMMENDED PRACTICES for Explosion-Protected Electri-cal Installations in General Industries,” published in 1979

1. GeneralThe following describes precautions on electrical apparatusof intrinsically safe construction (hereinafter referred to asintrinsically safe apparatus).

Following the Labor Safety and Health Laws of Japan, anintrinsically safe apparatus must undergo type tests in orderto be certified by the Technical Institute of Industrial Safety,Inc. These tests are required to satisfy either the technicalcriteria for electrical machinery and equipment in compliancewith explosionproof standards involving inflammable gasesor vapors and for machinery and equipment havingexplosionproof performance (standards notification no. 556

from the Japanese Ministry of Labor) (hereinafter referred toas technical criteria), in conformity with IEC Standards, orthe “Recommended Practice for Explosion-ProtectedElectrical Installations in General Industries,” published in1979. Such a certified apparatus can be used in hazardouslocations where inflammable gases or vapors may be present.

Certified apparatus includes a certification label and anequipment nameplate with the specifications necessary forexplosion requirements as well as precautions on explosionprotection. Please confirm these precautionary items and usethem to meet specification requirements.

For electrical wiring and maintenance servicing, please referto “Internal Wiring Rules” in the Electrical InstallationTechnical Standards as well as “USER’S GUIDELINES forElectrical Installations for Explosive Gas Atmospheres inGeneral Industry,” published in 1994.

To meet intrinsically safe requirements, equipment that canbe termed an “intrinsically safe apparatus” must:

(1) be certified by the Technical Institute of IndustrialSafety, Inc. in accordance with the Labor Safety andHealth Laws of Japan and have the appropriate mark ofcertification labeled on its case, and

(2) be used in compliance with the specifications marked onits certification label, equipment nameplate and

precautionary information furnished.

Note: Intrinsically safe apparatus satisfy their performance underspecific conditions. They are not always absolutely safe underevery operational and environmental condition. In other

words, they are not safe products involved with factors suchas chemical reactions, geographical changes or the like otherthan affected by electric energy from the equipment itself.

2. Electrical Apparatus of IntrinsicSafety Type of Explosion-Pro-tected Construction

The intrinsic safety type of explosion-protected constructionis a method of protection applicable to a circuit or part of acircuit in which, under prescribed test conditions, no spark orthermal effect, whether produced normally or accidentally, iscapable of causing a prescribed explosive gas to ignite. Inother words, electrical apparatus of this construction isintended to suppress electrical energy thereby preventingignition of a given explosive gas atmosphere even though

spark or high thermal effect occurs in the electric circuitry.

Intrinsically safe electrical apparatus generally compriseintrinsically safe apparatus installed in a hazardous location

and a safety barrier (associated apparatus), installed in a non-hazardous location, aimed at preventing electrical energyfrom flowing into the electric circuitry of intrinsically safeapparatus.

However, battery-operated, portable intrinsically safeapparatus or the like may be used alone.

3. Terminology(1) Intrinsically safe apparatus: Electrical apparatus in which

all the circuits are intrinsically safe circuits.(2) Associated apparatus: Electrical apparatus in which there

are both intrinsically safe circuits and non-intrinsicallysafe circuits that can affect the safety of intrinsically safecircuits.

(3) Safety barrier: A specific type of associated apparatus,which consists mainly of safety barrier elements, andserves to limit the flow of excessive electrical energy,which is capable of causing ignition of a given explosivegas or vapour of a non-intrinsically safe circuit intoconcerned intrinsically safe circuits.

(4) Apparatus of category “ia”: Intrinsically safe electricalapparatus and associated apparatus which are incapableof causing ignition of a given explosive gas or vapourwith the appropriate safety factors such as:

EX-A03E2


— when up to two countable faults are applied and, inaddition,

— when non-countable faults produce an onerouscondition.

(5) Apparatus of category “ib”: Intrinsically safe electrical

apparatus and associated apparatus which are incapableof causing ignition of a given explosive gas or vapour,with the appropriate safety factors such as:— when up to one countable fault is applied and, in

addition,— when non-countable faults produce an onerous

condition.(6) Safety rating: A rating to be designated to intrinsically

safe apparatus as well as associated apparatus and is themaximum rating allowable for maintaining intrinsicsafety of concerned intrinsically safe circuits.

4. Caution on Combining Intrinsi-cally Safe Apparatus andSafety Barriers

(1) A combination of certified intrinsically safe apparatusand safety barriers needs to satisfy combinationrequirements. If intrinsically safe apparatus specifysafety barriers for combination, safety barriers other thanspecified cannot be used (see Note 1 for more details).

(2) Certified intrinsically safe systems specify specific safetybarriers in combination with intrinsically safe apparatus.So safety barriers other than specified cannot be used(see Note 2 for more details).

(3) Other than limitations of combining intrinsically safe

apparatus and safety barriers as given in (1) and (2)above, two or more pieces of apparatus certified underdifferent standards cannot be combined with each other(see Note 3 for more details). In addition, bear in mindthat classifications of explosion protection such as “IIA,”“IIB” and “IIC” and category “ia” and “ib” limit acombination of intrinsically safe apparatus and safetybarriers.For more details, see the “Type Certificate Guide forExplosion-Protected Constructionfor ElectricalMachinery and Equipment,” issued by the JapaneseMinistry of Labour, the Research Institute of Industrial

Safety.

Note 1: Testing ApparatusIntrinsically safe apparatus and safety barriers are assessedindividually to ensure that their safety requirements aresatisfied. Tested and certified intrinsically safe apparatus andsafety barriers incorporate individual certification numbers.A combination of intrinsically safe apparatus and safetybarriers involves the following two limitations:(1) A safety barrier which meets the combination require-

ments by referring to its safety rating and combinationparameters shall be selected.

(2) For pressure transmitters, pH transmitters, temperaturedetectors and the like, safety barriers that can becombined are already specified. Other safety barrierscannot be used.

Note 2: Testing Intrinsically Safe SystemAn assembly (as a system) in which intrinsically safeapparatus and safety barriers are combined is assessed toensure that its safety requirements are satisfied. A tested andcertified system incorporates a certification number(intrinsically safe apparatus and safety barriers have the samecertification number).

Note 3: Impossible Combinations of Apparatus Certified UnderDifferent StandardsIntrinsically safe apparatus certified under technical criteriaand safety barriers certified under the “RecommendedPractice for Explosion-Protected Electrical Installations inGeneral Industries” (1979) and vice versa cannot becombined even if their combination requirements aresatisfied.

5. Installation of Intrinsically SafeApparatus and Safety Barriers

(1) Classification of installation locationIntrinsically safe apparatus may be installed, depending uponapplicable gases, in a hazardous area in Zone 0, 1 or 2 (Note4 below), where the specified gases are present. However,note that apparatus certified under Technical Criteria, incategory “ib” shall be installed only in Zone 1 or 2. Safetybarriers (associated apparatus) that are combined with theseintrinsically safe apparatus shall be installed only in a non-

hazardous area. In cases where safety barriers are installed ina hazardous area, they shall be enclosed, for example, in aflameproof enclosure.

Note 4: Hazardous areas are classified in zones based upon thefrequency of the appearance and the duration of an explosivegas atmosphere as follows:Zone 0: An area in which an explosive gas atmosphere is

present continuously or is present for long periods.Zone 1: An area in which an explosive gas atmosphere is

likely to occur in normal operation.Zone 2: An area in which an explosive gas atmosphere is not

likely to occur in normal operation and if it doesoccur it will exist for a short period only.

(2) Ambient temperature limits for intrinsicallysafe apparatus

Intrinsically safe apparatus shall be installed in a location

where the ambient temperature ranges from –20° to +40°C(for those certified under Technical Criteria) or –10° to+40°C (for those certified under the “Recommended Practicefor Explosion-Protected Electrical Installations in GeneralIndustries” (1979). However, some field-mounted

EX-A03E3


intrinsically safe apparatus may be used at an ambienttemperature up to 60°C. So, specifications should be checkedbefore installing intrinsically safe apparatus.

If the intrinsically safe apparatus are exposed to directsunshine or radiant heat from plant facilities, appropriatethermal protection measures shall be taken.

6. Wiring for Intrinsically SafeCircuits

In intrinsically safe construction, safety shall be maintainedas an intrinsically safe system involving intrinsically safeapparatus and safety barriers connected thereto, and electricalwiring (through intrinsically safe circuits) interconnectedbetween them. In other words, even when safety

requirements are maintained individually by intrinsically safeapparatus and safety barriers, they shall not be affected byelectrical or magnetic energy caused by electrical wiring.

To make electrical wiring for intrinsically safe circuits, youmust:

(a) refer to the equipment configuration diagram and makeelectrical wiring properly;

(b) prevent intrinsically safe wiring from being contactedwith non-intrinsically safe wiring, and separate theintrinsically safe circuit from other electrical circuits;

(c) prevent intrinsically safe wiring from beingelectrostatically and magnetically affected by non-intrinsically safe wiring;

(d) reduce wiring inductance and capacitance producedbetween the intrinsically safe apparatus and safetybarrier where possible, and use a shorter cable betweenthe intrinsically safe apparatus and safety barrier thanspecified if the maximum permissible inductance of the

cable is specified as operating conditions;(e) conform to conditions of installation such as wiring

method, earthing or the like, if any; and(f) protect the outer sheath of cables from damage with

appropriate measures.

7. Maintenance and Inspection ofIntrinsically Safe Apparatusand Safety Barriers

Maintenance and inspection of intrinsically safe apparatusand safety barriers shall be limited to within the instructionsdescribed in applicable instruction manuals. If other than this

is required, contact the manufacturers. For more information,refer to the “USER’S GUIDELINES for Electrical

Installations for Explosive Gas Atmospheres in GeneralIndustry” issued in 1994 by the Japanese Ministry of Labour,the Research Institute of Industrial Safety.

(1) Requirements for maintenance personnelMaintenance and inspection of intrinsically safe apparatusand safety barriers shall be conducted by maintenancepersonnel skilled in intrinsically safe construction and

installation of electrical devices as well as capable ofapplying associated rules.

(2) Maintenance and Inspection(a) Visual inspection

Visually inspect the external connections of intrinsicallysafe apparatus and safety barriers, and cables for damageor corrosion as well as other mechanical and structuraldefects.

(b) AdjustmentsZero, span and sensitivity adjustments shall be madewith applicable adjusting potentiometers and mechanicaladjustment screws.These maintenance adjustments shall be made in a non-hazardous location.

CAUTION

If intrinsically safe apparatus and safety barriersrequire maintenance service and checking, agas detector shall be used to ensure that thereis no explosive gas in the location (mainte-nance servicing shall be conducted in a non-hazardous location).

(3) RepairIntrinsically safe apparatus and safety barriers shall berepaired by manufacturers.

(4) Prohibition of modifications and specifica-tion changes

Do not attempt to make modifications or change specifica-tions which may affect safety.

INSTALLATION AND OPERATING PRECAUTIONS FOR TIIS FLAMEPROOF EQUIPMENT

INSTALLATION AND OPERATING PRECAUTIONS FORTIIS FLAMEPROOF EQUIPMENT

Apparatus Certified Under Technical Criteria(IEC-compatible Standards)

1. GeneralThe following describes precautions on electrical apparatusof flameproof construction (hereinafter referred to asflameproof apparatus) in explosion-protected apparatus.

Following the Labour Safety and Health Laws of Japan,flameproof apparatus is subjected to type tests to meet eitherthe technical criteria for explosionproof electrical machineryand equipment (standards notification no. 556 from the

Japanese Ministry of Labour) (hereinafter referred to astechnical criteria), in conformity with the IEC Standards, orthe “Recommended Practice for Explosion-ProtectedElectrical Installations in General Industries,” published in1979. These certified apparatus can be used in hazardouslocations where explosive or inflammable gases or vapoursmay be present.

Certified apparatus includes a certification label and anequipment nameplate with the specifications necessary forexplosion requirements as well as precautions on explosionprotection. Please confirm these precautionary items and usethem to meet specification requirements.

For electrical wiring and maintenance servicing, please referto “Internal Wiring Rules” in the Electrical InstallationTechnical Standards as well as “USER’S GUIDELINES forElectrical Installations for Explosive Gas Atmospheres inGeneral Industry,” published in 1994.

To meet flameproof requirements, equipment that can betermed “flameproof” must:

(1) Be certified by a Japanese public authority in accordancewith the Labour Safety and Health Laws of Japan andhave a certification label in an appropriate location on itscase, and

(2) Be used in compliance with the specifications marked onits certification label, equipment nameplate andprecautionary information furnished.

2. Electrical Apparatus of Flame-proof Type of Explosion-Pro-tected Construction

Electrical apparatus which is of flameproof construction issubjected to a type test and certified by the Japanese Ministryof Labour aiming at preventing explosion caused by electricalapparatus in a factory or any location where inflammable

gases or vapours may be present. The flameproof

construction is of completely enclosed type and its enclosureshall endure explosive pressures in cases where explosivegases or vapours entering the enclosure cause explosion. Inaddition, the enclosure construction shall be such that flamecaused by explosion does not ignite gases or vapours outsidethe enclosure.

In this manual, the word "flameproof" is applied to theflameproof equipment combined with the types of protection"e", "o", "i", and "d" as well as flameproof equipment.

3. Terminology

(1) EnclosureAn outer shell of an electrical apparatus, which encloses liveparts and thus is needed to configure explosion-protected

construction.

(2) ShroudA component part which is so designed that the fastening ofjoint surfaces cannot be loosened unless a special tool isused.

(3) Enclosure internal volumeThis is indicated by:— the total internal volume of theflameproof enclosure minus the volume of the internalcomponents essential to equipment functions.

(4) Path length of joint surfaceOn a joint surface, the length of the shortest path throughwhich flame flows from the inside to outside of theflameproof enclosure. This definition cannot be applied tothreaded joints.

(5) Gaps between joint surfacesThe physical distance between two mating surfaces, ordifferences in diameters if the mating surfaces are cylindrical.

Note: The permissible sizes of gaps between joint surfaces, the pathlength of a joint surface and the number of joint threads aredetermined by such factors as the enclosure’s internalvolume, joint and mating surface construction, and theexplosion classification of the specified gases and vapours.

EX-B03E2


4. Installation of Flameproof Ap-paratus

(1) Installation AreaFlameproof apparatus may be installed, in accordance withapplicable gases, in a hazardous area in Zone 1 or 2, wherethe specified gases are present. Those apparatus shall not beinstalled in a hazardous area in Zone 0.

Note: Hazardous areas are classified in zones based upon thefrequency of the appearance and the duration of an explosivegas atmosphere as follows:Zone 0: An area in which an explosive gas atmosphere is

present continuously or is present for long periods.Zone 1: An area in which an explosive gas atmosphere is

likely to occur in normal operation.Zone 2: An area in which an explosive gas atmosphere is not

likely to occur in normal operation and if it doesoccur it will exist for a short period only.

(2) Environmental ConditionsThe standard environmental condition for the installation offlameproof apparatus is limited to an ambient temperaturerange from –20°C to +40°C (for products certified under

Technical Criteria). However, some field-mountedinstruments may be certified at an ambient temperature up to+60°C as indicated on the instrument nameplates. If theflameproof apparatus are exposed to direct sunshine orradiant heat from plant facilities, appropriate thermalprotection measures shall be taken.

5. External Wiring for FlameproofApparatus

Flameproof apparatus require cable wiring or flameproofmetal conduits for their electrical connections. For cablewiring, cable glands (cable entry devices for flameproof type)to wiring connections shall be attached. For metal conduits,attach sealing fittings as close to wiring connections aspossible and completely seal the apparatus. All non-livemetal parts such as the enclosure shall be securely grounded.For details, see the “USER’S GUIDELINES for ElectricalInstallations for Explosive Gas Atmospheres in GeneralIndustry,” published in 1994.

(1) Cable Wiring• For cable wiring, cable glands (cable entry devices for

flameproof type) specified or supplied with the apparatusshall be directly attached to the wiring connections tocomplete sealing of the apparatus.

• Screws that connect cable glands to the apparatus are

those for G-type parallel pipe threads (TIIS B 0202) withno sealing property. To protect the apparatus fromcorrosive gases or moisture, apply nonhardening sealantsuch as liquid gaskets to those threads for waterproofing.

• Specific cables shall be used as recommended by the“USER’S GUIDELINES for Electrical Installations forExplosive Gas Atmospheres in General Industry,”published in 1994.

• In necessary, appropriate protective pipes (conduit or

flexible pipes), ducts or trays shall be used forpreventing the cable run (outside the cable glands) fromdamage.

• To prevent explosive atmosphere from being propagatedform Zone 1 or 2 hazardous location to any differentlocation or non-hazardous location through the protectivepipe or duct, apply sealing of the protective pipes in thevicinity of individual boundaries, or fill the ducts withsand appropriately.

• When branch connections of cables, or cable connectionswith insulated cables inside the conduit pipes are made,a flameproof or increased-safety connection box shall be

used. In this case, flameproof or increased-safety cableglands meeting the type of connection box must be usedfor cable connections to the box.

(2) Flameproof Metal Conduit Wiring• For the flameproof metal conduit wiring or insulated

wires shall be used as recommended by the USER’SGUIDELINES for Electrical Installations for ExplosiveGas Atmospheres in General Industry, published in1994.

• For conduit pipes, heavy-gauge steel conduitsconforming to TIIS C 8305 Standard shall be used.

• Flameproof sealing fittings shall be used in the vicinityof the wiring connections, and those fittings shall befilled with sealing compounds to complete sealing of theapparatus. In addition, to prevent explosive gases,moisture, or flame caused by explosion form being

propagated through the conduit, always provide sealingfittings to complete sealing of the conduit in thefollowing locations:

(a) In the boundaries between the hazardous and non-hazardous locations.

(b) In the boundaries where there is a differentclassification of hazardous location.

• For the connections of the apparatus with a conduit pipeor its associated accessories, G-type parallel pipe threads(TIIS B 0202) shall be used to provide a minimum offive-thread engagement to complete tightness. Inaddition, since these parallel threads do not have sealing

property, nonhardening sealant such as liquid gasketsshall thus be applied to those threads for ensuringwaterproofness.

• If metal conduits need flexibility, use flameproof flexiblefittings.

EX-B03E3


6. Maintenance of FlameproofApparatus

To maintain the flameproof apparatus, do the following. (Fordetails, see Chapter 10 “MAINTENANCE OF EXPLOSION-PROTECTED ELECTRICAL INSTALLATION” in theUSER’S GUIDELINES for Electrical Installations forExplosive Gas Atmospheres in General Industry.)

(1) Maintenance servicing with the power on.Flameproof apparatus shall not be maintenance-serviced withits power turned on. However, in cases where maintenanceservicing is to be conducted with the power turned on, withthe equipment cover removed, always use a gas detector tocheck that there is no explosive gas in that location. If itcannot be checked whether an explosive gas is present or not,maintenance servicing shall be limited to the following twoitems:

(a) Visual inspectionVisually inspect the flameproof apparatus, metal

conduits, and cables for damage or corrosion, and othermechanical and structural defects.

(b) Zero and span adjustmentsThese adjustments should be made only to the extentthat they can be conducted from the outside withoutopening the equipment cover. In doing this, great caremust be taken not to cause mechanical sparks with tools.

(2) RepairIf the flameproof apparatus requires repair, turn off the powerand transport it to a safety (non-hazardous) location. Observethe following points before attempting to repair theapparatus.

(a) Make only such electrical and mechanical repairs as willrestore the apparatus to its original condition. For theflameproof apparatus, the gaps and path lengths of jointsand mating surfaces, and mechanical strength ofenclosures are critical factors in explosion protection.Exercise great care not to damage the joints or shock theenclosure.

(b) If any damage occurs in threads, joints or matingsurfaces, inspection windows, connections between thetransmitter and terminal box, shrouds or clamps, orexternal wiring connections which are essential inflameproofness, contact Yokogawa Electric Corporation.

CAUTION

Do not attempt to re-process threaded connections orrefinish joints or mating surfaces.

(c) Unless otherwise specified, the electrical circuitry andinternal mechanisms may be repaired by componentreplacement, as this will not directly affect the

requirements for flameproof apparatus (however, bear inmind that the apparatus must always be restored to itsoriginal condition). If you attempt to repair theflameproof apparatus, company-specified componentsshall be used.

(d) Before starting to service the apparatus, be sure to checkall parts necessary for retaining the requirements forflameproof apparatus. For this, check that all screws,bolts, nuts, and threaded connections have properly beentightened.

(3) Prohibition of specification changes andmodifications

Do not attempt to change specifications or makemodifications involving addition of or changes in externalwiring connections.

7. Selection of Cable Entry De-vices for Flameproof Type

IMPORTANT

The cable glands (cable entry devices for flameprooftype) conforming to IEC Standards are certified incombination with the flameproof apparatus. So,Yokogawa-specified cable entry devices for flameprooftype shall be used to meet this demand.
