4.2.2 Wiring(1) Install wiring away from noise sources such as

a large capacity transformer, motor, or power supply.

(2) Remove terminal box cover and wiring connection dustproof plugs, then connect wiring.

UsinganAllenwrench(width3mm),unscrewthelockingsetscrewandremovetheflameproofcover.

Then, connect the wiring and when installing the cover, do not neglect to fasten shrouding metal.

(3) It is recommended that clip-on terminals R1.25-5 or R2-5 be used for wiring termination (JIS C 2805).

(4) It is also recommended that wiring be installed in conduits and ducts to provide protection against water or external damage. For flameproofexternalwiring,see1.6InstallationofFlameproofType”and“InstallationandOperating Precautions for TIIS Flameproof Equipment”attheendofthismanual.

(5) Wheninstallingaflameproofglandpackingadapter(optioncode:/G11and/G21)forcablewiring, observe the following steps.a. Release the shrouding metal and remove the

terminal box cover.b. Measure the outside dia. of the cables to be

used in two directions in 0.1mm unit.c. Obtain the average value of the measured

values in two directions and select a gland packing whose inner dia. is nearest to the average value from among those in Table 4.1.

d.Screwtheflameproofpackingadapterintothe terminal box until the O-ring touches the terminal box wiring port (at least 6 full turns), and tighten the lock nut.

e. Insert the cable through the union cover, the union coupling, the clamp nut, the clamp ring, the gland, one washer, the rubber packing, and the packing box, in that order.

f. Insert the end of the cable into the terminal box.

g. Tighten the gland to grip the cable. When tightening the union cover, tighten approximately one turn past the point where the cable will no longer move up and down.

Proper tightening is important. If it is too tight, a circuit break in the cable may occur; if not tightenough,theflameproofeffectivenesswill be compromised.

CAUTIONTighten the gland approximately one turn after the point where you can no longer shift the cable up and down by hand.Take great care in this step, since proper tightening is very important.

h. Fasten the cable with tightening the clamp nut.

i. Tighten the lock nut on the union cover.j. Connectthecablewirestoeachterminal.

Ifproblemappearsdifficulttocorrect,consultYOKOGAWA service personnel.

7.2 OperationPrincipleThe PK200 current-to-pneumatic converter accepts a 4 to 20mA or 10 to 50mA current signal from an electronic controller as an operating signal. This signalisinputtoatorquemotorviaanelectriccircuit,generatingatorqueproportionaltothecurrent signal.

Anincreaseintheinputsignalcausestheflapperattheendofthetorquemotormovingpiecetomovein the nozzle closing direction. When the nozzle is closed, back pressure increases, displacing the input diaphragm inside the control relay. This causes the control relay output air pressure to increase.

This output air pressure is output as PK200 converter output pressure and is also input to a feedback pressure sensor. The sensor then converts the pressure input into an electric signal, which is fed back to the electric circuit. The signal is then compared with the manipulated output signal, theresultofwhichactivatesmodificationactionuntil an output air pressure balanced with the input signal is obtained.

In this way, an output air pressure proportional to the input signal, which is a manipulated output signal, is obtained.

AppendixA.AirSupplySystem1. OverviewPneumatic industrial instruments are one of the most maintenance-free, highly reliable industrial instrument systems and are in wide use. Such features are fully demonstrated only when suitable service conditions where the characteristics of pneumaticinstrumentsaresufficientlytakenintoaccount are established.

One of such service conditions includes an air supplysystem.Pneumaticinstrumentsrequireclean,dryairandthus,anaftercooler,filter,andair drier are installed after a compressor to prevent water, oil, and other contaminants from entering into the instruments. Also, care should be exercised as described below at service points.

2. AirSupplySystem

(1) ExampleofPanel-MountingInstrument

When air is to be supplied to multiple instruments it is recommended that two reducing valves are used in parallel as shown in Figure A.1. Parallel arrangement protects instruments from interference even if one reducing valve is suspended due to clogging. Also, use of a three-way cock as shown in Figure A.1 allows any of air supply systems to be separated for maintenance. Generally, both air supply systems are used in parallel for operation. To supply clean and dry air to instruments, considerations should be made, such as provision ofwaterdrain,filter,anddownwardpitch(1/100ormore) for piping.

• SupplyAirClean,dryairisrequired.Anaftercooler,filter,air drier are used to eliminate water, oil, and other contaminants.

• AirSupplyHeader(AirHeader)The air header that supplies air to a series of instruments is installed with a minimum downwardpitchof10mm/m(1/100)sothatmoisture and oil entrapped in the header can be discharged.

• AirSupplyPipingAn air supply pipe connected to an instrument is branched from the upper part of an air header to prevent moisture entry. Even if this is not possible, an air supply pipe should be branched from the side of the air header, i.e., it must not be branched from the bottom part of the header.It is recommended that an air supply pipe be provided with a shut-off valve so that individual instruments can be removed.

• AirFilterAfilterremovesmoisture,oil,andothercontaminants that cannot be removed by the main air supply system. In general a cockinstalledatthebottomofafilterisopened to discharge moisture, oil, and other contaminants. If the amount of moisture and oil is large, increase the number of draining times.

Note: Intrinsicallysafeapparatussatisfytheirperformanceunderspecificconditions.Theyarenotalwaysabsolutelysafeunderevery operational and environmental condition. In other words, they are not safe products involved with factors such as chemical reactions, geographical changes or the like other than affected by electricenergyfromtheequipmentitself.

2. ElectricalApparatusofIntrinsicSafetyTypeofExplosion-ProtectedConstruction

The intrinsic safety type of explosion-protected construction is a method of protection applicable to a circuit or part of a circuit in which, under prescribed test conditions, no spark or thermal effect, whether produced normally or accidentally, is capable of causing a prescribed explosive gas to ignite. In other words, electrical apparatus of this construction is intended to suppress electrical energy thereby preventing ignition of a given explosive gas atmosphere even though spark or high thermal effect occurs in the electric circuitry.Intrinsically safe electrical apparatus generally comprise intrinsically safe apparatus installed in a hazardous location and a safety barrier (associated apparatus), installed in a non-hazardous location, aimed at preventing electrical energy from flowingintotheelectriccircuitryofintrinsicallysafeapparatus.However, battery-operated, portable intrinsically safe apparatus 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-intrinsically safe circuits that can affect the safety of intrinsically safe circuits.

(3) Safetybarrier:Aspecifictypeofassociatedapparatus,whichconsists mainly of safety barrier elements, and serves to limittheflowofexcessiveelectricalenergy,whichiscapableof causing ignition of a given explosive gas or vapour of a non-intrinsically safe circuit into concerned intrinsically safe circuits.

(4) Apparatusofcategory“ia”:Intrinsicallysafeelectricalapparatus and associated apparatus which are incapable of causing ignition of a given explosive gas or vapour with the appropriate safety factors such as:- when up to two countable faults are applied and, in

addition, - when non-countable faults produce an onerous condition.

(5) Apparatusofcategory“ib”:Intrinsicallysafeelectricalapparatus and associated apparatus which are incapable of 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 the maximum rating allowable for maintaining intrinsic safety of concerned intrinsically safe circuits.

4. Caution on Combining Intrinsically Safe ApparatusandSafetyBarriers

(1) Acombinationofcertifiedintrinsicallysafeapparatusandsafetybarriersneedstosatisfycombinationrequirements.If intrinsically safe apparatus specify safety barriers for combination,safetybarriersotherthanspecifiedcannotbeused(seeNote1formoredetails).

(2) Certifiedintrinsicallysafesystemsspecifyspecificsafetybarriers in combination with intrinsically safe apparatus. So safetybarriersotherthanspecifiedcannotbeused(seeNote2formoredetails).

(3) Other than limitations of combining intrinsically safe apparatus and safety barriers as given in (1) and (2) above, twoormorepiecesofapparatuscertifiedunderdifferentstandardscannotbecombinedwitheachother(seeNote3formoredetails).Inaddition,bearinmindthatclassificationsofexplosionprotectionsuchas“IIA,”“IIB”and“IIC”andcategory“ia”and“ib”limitacombinationofintrinsicallysafeapparatus and safety barriers.

Formoredetails,seethe“TypeCertificateGuideforExplosion-Protected Construction for Electrical Machinery andEquipment,”issuedbytheJapaneseMinistryofLabour,the Research Institute of Industrial Safety.

Note1: TestingApparatus Intrinsically safe apparatus and safety barriers are assessed individuallytoensurethattheirsafetyrequirementsaresatisfied.Testedandcertifiedintrinsicallysafeapparatusandsafetybarriersincorporateindividualcertificationnumbers. A combination of intrinsically safe apparatus and safety barriers involves the following two limitations:
