2.Selection of transmitter adjustment methodLOCAL/COMM. Changing switch decides the method of FCX-AII transmitter adjustment. If switchis set to “COMM.” side, adjustment of transmitter is carried out by HHC. This method is explainedin instruction manual.If switch is set to “LOCAL” side, adjustment of transmitter is carried out by Mode setting switchand Damping setting switch.This method is explain below.3.Range change procedureFor changing the measuring range, carry out zero adjustment first, and span adjustment next. (Ifzero adjustment is performed after span adjustment, the 100% point may not be adjusted correctly.).There is no interference between zero adjustment and span adjustment.3.1 Zero adjustment (Change Lower Range Value)Zero point of the transmitter is adjustable by the external adj. screw with the mode settingswitch set at “0” position.(1) Check if “ZERO” is lit on the LCD indicator.If not lit, set the mode setting switch to “0” position.(2) Apply standard input pressure corresponding to new Lower Range Value(3) Adjust output signal to 4.00mA by turning the external adj. screwDecreaseIncreaseFor zero suppression or elevation ranges, apply the specified LRV pressure in advance and adjustthe output signal to 4.00mA using the external adj. screw.Max zero elevation with :max spanOutputsignalmin span100% (20mA)Max Zero suppression with :min spanmax span-100%0%(4mA)0%Zero elevation Zero suppressionInput signal%URL+100%31

3.2 Span adjustment (Change Upper Range Value)The measuring range for each transmitter is determined according to its type.The span is changed by the external adj. screw when the mode setting switch is set at “1” or ”6"position.(1) Set the mode setting switch to “1” or ”6” position.(2) Apply standard input pressure corresponding to new Upper Range Value.(3) Adjust output to 20.00mA by turning the external adj. screw.DecreaseIncrease(4) Then, apply input pressure corresponding to new Lower Range Value again and make sureoutput is 4mA.(5) After span adjustment according to above procedure from 3.2-(1) to (4), please set modesetting switch to appropriate positionImportantAfter adjustment, the transmitter should be kept energized at about 10 seconds to writethe adjustment parameter into memory.4. Damping adjustmentIf a pulsation of the output current is caused due to flow noise etc., it can be attenuated by performingdamping adjustment.Damping is adjustable in 8 steps. The damping constant becomes lager in the order of 0,1,2,3and 4.These damping constant correspond to time constant 0, 0.3, 0.6, 1.2, 2.4, 4.8, 9.6, 19.2 seconds for thetransmission unit regardless of span.The relationship between position of switch and time constant are indicated in table 2.Note)The damping constant above is a time constant applied to the transmission unit only. Thedetecting unit has additional time constant(Please see data sheet about details)ImportantWhen the transmitter respose speed is changed, the time constant of the control systemis also changed. Be sure to check the controllability again.5. Fixed current output and its adjustmentOutput of fixed current regardless of input is available.Output of fixed current is convenient for loop check.When the output(4 or 20mA)is in error, it can be adjusted by the external adjustment screw.32

5. MAINTENANCE5.1 Periodic inspectionIn order to ensure the measurement accuracy and long life of the transmitter, it is essential to inspectthe transmitter periodically according to the operating conditions.Visual inspectionVisually inspect each part of the transmitter for damage, corrosion, etc.If you detect any material which may cause corrosion, it should be cleaned off.Check of cover and O-ringThe transmitter has a water and dust-proof construction.Make sure the O-ring of the case cover is not damaged or deteriorated.Carefully prevent foreign materials from sticking to threads.Piping leakage checkUsing soapy water or the like, check the all process connections for leakage of process fluid.

6. INSTALLATION AND PIPING6.1 InstallationAfter unpacking, check the delivered items.This transmitter can be mounted on a pipe or on a wall.(However, level transmitters (types: FKE) require flange mounting).Note that the bolts (M8) for wall mounting should be supplied by the customer.CAUTION• The transmitter is heavy. Be careful when handling it.• The transmitter should be installed in a place that meets the operating conditionsshown in DS sheet or instruction manual.• Install the transmitter according to the instruction manual. Improper installation maylead to the cause of fall, trouble or incorrect operation.• When installing, make sure that the transmitter interior is free from cable chips andother foreign objects to prevent fire, trouble or incorrect operation.DANGER• Non-explosion-proof transmitter must not be used in a place with explosive gas toprevent serious accidents such as explosion, fire, etc.ImportantIf the transmitter is not used soon after delivery, then leave it packed and store it in aroom at the normal temperature and humidity (25°C , 60%RH).Bracket mountingMount the bracket to the transmitter.The bracket should be mounted to the process cover as shown below.(Differential pressure/flow transmitters, pressure (Remote seal type transmitters, types: FKD, FKB,transmitters, and absolute pressure transmitters, types: FKM)FKC, FKG, FKA)MountingPipe mountingTransmitterMesurement chamber coverBracketPlain washerSpring washerMounting bolt(M8 12)(1) Fasten the transmitter to a vertical or horizontalpipe using the supplied U-bolt(Tightening torque approximately 15 N·m(1.5 kgf·m)).(2) Use a pipe of outside diameterø60.5

6.2 PipingIt is generally recognized that there are appropriate positioning relationship between the transmitterand main process piping for accurate measurement to avoid harmful gas or liquid accumulation.General recognizations are;1 Mount transmitter below main process piping for liquid or steam measurement.2 Mount transmitter above main process piping for gas measurement.The standard style of FCX-A2 series transmitter correspond to the piping procedure 1 mentionedabove. Change the vent/drain plug to correspond to the piping procedure 2.CAUTIONMain valve used for piping should be selected with the maximum pressure of the processtaken into account (piping parts such as main valve, etc. should be furnished byuser). If the main valve and other parts do not meet the rating, it may result in leakageof gas or liquid which could lead to a hazard.6.2.1 Piping of differential pressure and flow transmitters (type: FKC.)Check of high/low pressure sides of transmitterThe detecting unit of the differential pressure transmitterbears symbols H and L which represent high and low pressuresides, respectively.Also, vent/drain plugs are provided at the lower processconnection, while impulse pipes are connected at the upperprocess connections.LHRemoval of protective capThe process connection ports of the transmitter and manifold (equalizer) valve are fitted withprotective caps. Before piping, be sure to remove the caps. When removing the caps, carefullyprotect the threaded portion and sealing face from damage.Connection of transmitter and impulse pipes(1) When using the manifold valve, it should be fixed to the transmitter by tightening four ovalflange setbolts (7/16-20UNF), and then the impulse pipe should be connected to the manifoldvalve. Tightening torque of 7/16-20UNF mounting bolt should be 30 to 40 N·m (3 to 4 kgf·m).(2) If a manifold valve is not used, the impulse pipes can directly be screwed into the transmitter. Ifthread size does not match between the transmitter and impulse pipes, an oval flange should beused. Tightening torque of 7/16-20UNF mounting bolt in an oval flange should be 30 to 40 N·m(3 to 4 kgf·m).Position of process taps (Horizontal main process piping)The position of the process tap is determined by the relationship between the condition, characteristicsand measuring point of the process fluid.Note the following figures when planning and installing the piping.Gas measurementLiquid measurementSteam measurement45°45°UpperMain process pipingUpperDifferential pressure source45°45°Lower45°45°LowerDifferential pressuresource is located upperside of main process pipingWithin 45°upward fromvertical directionDifferential pressuresource is located lowerside of main process pipingWithin 45° downwardfrom horizontal directionDifferential pressuresource is located upperside of main process pipingWithin 45° upward fromhorizontal direction47

7. WIRINGCautions on wiring(1) Application of a voltage exceeding 60 V DC or 40 V AC (exceeding 33 V DC or 23 V AC whenarrester equipped) between “+” and “–” terminals may result in damage to the transmitter.(2) Use a shielded cable for the transmission line where possible.(3) Avoid installation of signal cable and power cable in same conduit or cable tray in order toprevent increased noise. Also, do not bring the signal cable close to large electrical equipment.DANGERIn case of an explosionproof arrangement, wiring shall be made in accordance with therelevant regulations to ensure the explosionproofing.7.1 Wiring procedureCAUTION• Before making wiring work, be sure to turn OFF the main power to prevent electricshocks.• Use wiring materials of correct rating to prevent fire accidents.• After installing the transmitter, firmly close the covers of the transmission unit andterminal box. If not, rain water enter the transmitter which may result in trouble orincorrect operation.Sealing of conduit connectionUse sealing tape, if using metal pipe screw coupling or rubber gasket and fastening gland in the caseof cable (outside diameter ø11)

Terminal block connection diagramTighten the terminal screws (M4 ✕ 10) to a torque of approximately 1.5 N·m (15 kgf·cm) so that the wires will not loosen.After connection, fasten the cover until it does not turn.Terminal–CK–CK++10.5 to 45 V DCOutput DC4 to 20mAConveterWhen using an external field indicatorFor direct connection to an external field indicator, connect the “+” and “–” sides of the fieldindicator to CK+ and CK– of the transmitter as shown below.Use an external field indicator with internal resistance of 12Ω or less.4 to 20mA DC–+–CK –CK++10.5 to 45 V DCOutput DC4 to 20mAConverter62

Things convenient to know beforehandWhen using conduit connection at the top(In the case of 4th digit of type code “S, T, V, W, X”)For wiring from the top conduit connection, use the following procedure.(1) Remove the screw plug of the top conduit connection.(2) Screw the removed screw plug into the bottom conduit connection.(3) Insert the cable from the top and connect it.Hexagon keywrenchFlash screwImportant• The unused conduit connection is of great importance to flameproofing and moistureprevention. So be sure to tighten the flush screw and packing into the connection.• When performing an insulation check after wiring, use a Megger (insulation resistancemeter) of 250 V DC or less and avoid applying a high voltage. If an arrester isequipped, avoid the insulation resistance test and the dielectric strength measurement.7.2 Power voltage and load resistanceMake sure the load resistance of the wiring connected to the loop is within the range shown below.CAUTIONConnect power source of correct rating. Use of power source in excess of the ratingmay cause a fire.1533Load resistance ( )600250Operating zoneNote)010.5 16.1 24 45Power voltage (VDC)Note) For communication with HHC, minimum load resistance of 250 Ω required.63

7.3 GroundingCAUTIONThe transmitter must be grounded. Otherwise, it may cause electric shocks or incorrectoperation.Grounding terminals are provided at two places (at the inside of terminal box and on the side ofconduit connection).By any of the methods given below, ground the transmitter in compliance with the relevant stipulationin the standard on explosionproof installation (for example, grounding resistance 100 Ω or lessby one of the methods given below). In case of intrinsically safe and flameproof installation, be sureto use the ground terminal for grounding.Grounding of transmitter casingGrounding from ground terminal–CK –CK ++External grounding terminal64

A1 BUILT-IN ARRESTERGeneralAn arrester is used to protect a transmitter or receiver from an abnormal voltage such as lightningsurges induced into signal lines. A built-in type arrester is mounted behind the terminal unit. Anameplate marked “with arrester” is attached to the terminal unit of transmitter with a built-in arrester.InstallationThe built-in arrester should be used in combination with panel mounting type arrester (type PXC) fordistributor protection.+1PXC2–PTL–5E6 + ETransmitter(with arrester)Panel mountingtype arresterDistributorGroundingSince transmitter and arrester groundings are internally connected together, user have only to connectthe external grounding terminals to ground.Grounding terminal must be used, in case of the explosionproof or intrinsic safety type transmitter.FCX-A2 series transmitterGrounding terminal–CK –CK++External grounding terminalImportant1. Grounding resistance should be 100Ω or less.2. Avoid common grounding with a lightning rod.68

MaintenanceCheck of arrester• Measure output current from the transmitter check terminals and output current to flow intotransmitter (see figure below).When current is measured with an ammeter connected to CK+ and CK– terminals, the internalresistance of the ammeter should be 12Ω or less.• If the measured two output current are the same, the arrester is normal.• In case the measured values have a difference of 0.1% (0.016mA) or more, the arrester is notfunctioning.• In the above case, the arrester unit (terminal unit) should be replaced with a new one.Limitation of insulation resistance and dielectric strength testAn insulation resistance and dielectric strength test should be avoided as a rule, since it maydamage the arrester.Output measurement at check terminalsDigital voltmeterTo CK +To CK –Standard resistor(1 or 10 )Output measurement outside transmitter* Disconnect the wire from the – (minus)terminal and connect the measurementdevice a shown below.To (–) terminalDigital voltmeterTo (+) terminalDC powersupplyTo (+) side wiringTo (–) sidewiringStandard resistance69
