OUTLINE

The FCX-CII series transmitter detects the differential pressure or pressure of various

fluids, converts it into a current signal of 4 to 20 mA DC and transmits it.

All the adjustment functions are incorporated in the transmission unit for making

adjustments easily and exactly.

Transmitter settings (such as range and damping time constant, etc.) can be changed from

an HHC (Hand Held Communicator).

Principle

The operating principle of the FCX-CII series transmitter is shown in the block

diagram below.

The input pressure is changed into an electrostatic capacitance in the detecting unit.

The change proportional to the pressure undergoes conditioning and amplification in

the transmission unit, and is then output as a current of 4 to 20mA DC.

Output mode

The output mode is used to select the

proportional mode (proportional to in-

put differential pressure) or square

root extraction mode (proportinal to

flow rate) for output signal (4 to 20

mA). In case of square root extraction

mode, the cut point and the mode

below the cut point can be set. Under

display 2 , press <INC> or <DEC> for

selection of the square root extraction

mode or proportional mode.

Change of output mode

b OUT=SQR

Since display 7 is presented when the

square root extraction mode is

selected, the low flow cut point should

be set.

Cut point is adjustable within the range

of 0.00 to 20.00%. The cut point is

used for stabilizing output near 0%

when the square root extraction mode

is selected for output signal. There are

two modes; in one mode, proportional

output is selected for output below a

cut point (Fig. A) and in the other

mode, output is forcibly reduced to 0%

for output below a cut point (Fig. B).

Zero/span adjustment

Zero and span are adjustable by apply-

ing an actual pressure.

When pressing <LRV> under display 1

the screen for zero adjustment 2

appears, and that for span adjustment 5

appears when pressing <URV>.

Under display 2 , after applying actual

pressure equal to zero point, press

<ENT> two times. Zero adjustment will

be over.

When adjustment is made at any point

other than zero, input the pressure value

at that point at the display of 2 , then

press the <ENT> key at the display of 3

while applying a corresponding pres-

sure to the transmitter.

Under display 5 , after applying actual

pressure equal to desired span, press

<ENT> two times. Span adjustment

will be over.

When adjustment is made at any point

other than span, input the pressure value

at that point at the display of 5 , then

press the <ENT> key at the display of 6

while applying a corresponding pres-

sure to the transmitter.

Press LRV or URV at display of 1 .

When the following is displayed, it means that calibration can not be made because

Menu No. H: LINEARIZE is effective. In this case, set INVALID on the panel of

No. H: LINEARIZE.

1. Span adjustment should be performed after zero adjustment is completed.

2. When the actual input exceeds the adjustable range, [NOT CALB <CL>] is

displayed.

In this case, adjustment is required again.

Adjustable range

Zero adjustment: Within ±40% of maximum span

Span adjustment: Within ±20% of calibrated span

3. When the adjustment point does not meet the following condition,

[SETTING ERR<CL>] is displayed. In this case, adjustment is required again.

Calibration of output circuit (D/A)

The output circuit (D/A) should be

calibrated by the following procedure

when necessary.

Make calibration wiring transmitter

according to "Calibration" in Appen-

dix A2, and calibrate the output cir-

cuit with the HHC using the follow-

ing procedure.

When the <LRV> key is pressed at

the display of 1 , the display 2 for

4mA current output and its

calibration will appear on the screen.

When the <URV> key is pressed, the

display 7 for 20mA current output

and its calibration will appear on the

screen.

Under display 1 , input a desired

value within a range of 3.8 to 20.8mA

and then press <ENT> two times.

At this input value, a regulated cur-

rent output is available.

Under display 4 , input digital values

measured by digital voltmeter.

Under display 4 , the output circuit is

calibrated when pressing <ENT>.

After setting and calibrating the con-

stant current output, be sure to reset

the HHC display to the initial display.

In this way, the transmitter output is

reset to the measurement output. It

should be noted that if HHC is

removed from the transmitter loop or

the HHC power is turned OFF when

the constant current output has been

set, the transmitter output is retained

at the constant current output.

Programmable linearization function

User can set output compensation

against the input using 14

compensation points, (X1, Y1), (X2,

Y2)…(X14, Y14). Each compensation

value between (Xn, Yn) and (Xn+1,

Yn+1) is connected by first order

approximate formula.

This linearization function is useful to

compensate the tank figure in level

measurement application and the flow

rate of steam or gas in flow measure-

ment application .

Functions for LINEARIZE are

available for FXW Version 6.0 and

upward.

By pressing INC at display of 2 , the

display is shifted to the setting of LIN-

EARIZE POINT 3 . Press CHNG at

display of 3 and input POINT XX to

be compensated. Then press ENT and

the display will be shifted to 5 .

Press INC at display of 5 and the dis-

play will be shifted to y for selection of

<1> Lin. point: LP and <2> Comp.

value : CV.

Select <1> Lin. point: LP at display of

6 and input XXX.XX% to each point

(LP1-LP ).

At the completion of input to all the

compensated points, press ENT twice

and the write of LP will be finished.

At this time, the display is shifted to 6 .

Select <2> Comp. point: CV at display

of 6 and input XXX. XX% to each

point (CV1-CV ) in the same manner

as noted in <1> LP. At the completion

of input to all the compensated points,

press ENT twice and the write of CV

will be finished.

At the completion of write of compen-

sated program for LP/CV, press CL

Rerange (Set LRV/URV calibration)

(application to level measurement) at

change of level (LRV/URV)

Functions of RERANGE can be made

with FXW Version 6.0 or upward.

When the lower range value (LRV) and

uppeer range value (URV) need to be

adjusted again during measurement of

tank level, the measurement levels can

be changed at the same time by setting

the LRV or URV to be adjusted from

FXW.

Apply an input pressure required for

rerange of LRV at display of 3 and

press ENT twice.

In this way, the rerange of LRV is com-

pleted, then the new measurement

range LRV and URV, which conforms

to the actual input pressure, is dis-

played.

When rerange is made at a point other

than 0%, input the set value (PV%) of

that point at display of 3 , and press

ENT at display of 4 while applying a

corresponding pressure. In this way,

the measurement range can be changed

to the input corresponding to that pres-

sure.

Apply an input pressure required for

rerange of URV at display of 6 and

press ENT twice. The rerange of URV

is completed, then the new

measurement range LRV and URV

corresponding to the actual input pres-

sure is displayed. When rerange is

made at a point other than 100%, input

the set value (PV%) of that point at dis-

play of 6 and press ENT at display of

2.Selection of transmitter adjustment method

LOCAL/COMM. Changing switch decides the method of FCX-CII transmitter adjustment. If switch

is set to “COMM.” side, adjustment of transmitter is carried out by HHC. This method is explained

in instruction manual.

If switch is set to “LOCAL” side, adjustment of transmitter is carried out by Mode setting switch

and Damping setting switch.

This method is explain below.

3.Range change procedure

For changing the measuring range, carry out zero adjustment first, and span adjustment next. (If

zero 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 setting

switch 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

(4) Then, apply input pressure corresponding to new Lower Range Value again and make sure

output is 4mA.

(5) After span adjustment according to above procedure from 3.2-(1) to (4), please set mode

setting switch to appropriate position

4. Damping adjustment

If a pulsation of the output current is caused due to flow noise etc., it can be attenuated by performing

damping 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 the

transmission 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. The

detecting unit has additional time constant

(Please see data sheet about details)

Important

After adjustment, the transmitter should be kept energized at about 10 seconds to write

the adjustment parameter into memory.

Important

When the transmitter respose speed is changed, the time constant of the control system

is also changed. Be sure to check the controllability again.

5. Fixed current output and its adjustment

Output 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.

Removal of protective cap

The process connection ports of the transmitter and manifold (equalizer) valve are fitted with

protective caps. Before piping, be sure to remove the caps. When removing the caps, care-

fully protect 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 oval

flange setbolts (7/16-20UNF), and then the impulse pipe should be connected to the manifold

valve. 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 transmit-

ter. If thread size does not match between the transmitter and impulse pipes, an oval flange

should be used. 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, char-

acteristics and measuring point of the process fluid.

Note the following figures when planning and installing the piping.

Typical examples of piping

Flow measurement (in case of gas)

Place the transmitter above the differential pres-

sure source.

Flow measurement (in case of liquid)

Place the transmitter below the differential pres-

sure source.

Make piping so that gas in the impulse pipe is not

delivered to the transmitter, and incorporate gas

reservoirs as required.

Flow measurement (in case of steam)

Set two condensers at the same height near the

process tap. Fill the line between the condensers

and transmitter with condensed water.

Install a drain port as required.

air inlet

(1) Protection is required to prevent dust from entering through the atmospheric

air inlet after installation of the manifold valve.

(2) If process pressure range is narrow (below 10kPa (1000mmH2O)), the follow-

ing should be considered.

•Pressure variation due to wind around atmospheric air inlet

•Temperature variation near process taps

•Difference in atmospheric pressure between process tap and transmitter

location.

To overcome this, provide atmospheric pressure-side pipe with a proper orifice

and consider accommodating the transmitter and atmospheric air inlet in a box.

Important

Cautions on impulse piping

•For liquid, the impulse pipes should have an upward slope of 1/10 or more between the

process connection and the transmitter to prevent accumulation of gas, etc. in the detect-

ing unit.

•For gas, the impulse pipes should have a downward slope of 1/10 or more between the

process connection and transmitter to prevent accumulation of moisture, etc. in the de-

tecting unit.

•Do not bent the impulse pipes acutely near the pressure outlet port, to prevent gas or drain

from staying in the pipe.

•Take care not to apply an excessive force to the transmitter during connection.

•In order to prevent vibration of the transmitter body and capillary from interfering with

output, the transmitter body should be installed at a vibration-free place and the capillary

should be fixed to a stable support.

•The impulse pipes used should be suitable for the working temperature, pressure, etc.

•When the measuring fluid is likely to freeze in the cover of the measurement chamber,

the cover needs to be warmed up with steam or a heater.

the seal diaphragm.

Therefore, H1 should be set higher than the value shown in the table below.

• In order to prevent vibration, the transmitter body should be installed at a

vibration-free place.

• Do not shock the seal diaphragm by hitting hard object against it, for example.

• Take care not to apply an excessive force to the flange during connection.

WIRING

(1) Application of a voltage exceeding 60 V DC or 40 V AC (exceeding 32 V DC or 23 V AC

when arrester 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 to

prevent increased noise. Also, do not bring the signal cable close to large electrical equip-

ment.

7.1 Wiring procedure

Use sealing tape, if using metal pipe screw coupling or rubber gasket and fastening gland in the

case of cable (OD ø11) <0.43"> to ensure airtightness of the connection box.

pipe

Cautions on wiring

Sealing of conduit connection

In case of an explosionproof arrangement, wiring shall be made in accordance with

the relevant regulations to ensure the explosionproofing.

DANGER

•Before making wiring work, be sure to turn OFF the main power to prevent

electric shocks.

•Use wiring materials of correct rating to prevent fire accidents.

•After installing the transmitter, firmly close the covers of the transmission unit

and terminal box. If not, rain water enter the transmitter which may result in

trouble or incorrect operation.

CAUTION

1. If the connection box is located above the transmitter when using a protec-

tive tube for the wiring, then moisture may enter the protective tube and have

an adverse effect on the transmitter. So maintaining airtightness of the

connection box is an important practice.

2. The thread of conduit tube should meet the selected size and a seal fixture

should be used.

Important

Tighten the terminal screws (M4 x10) to a torque of approximately 1.5 N•m (15 kgf•cm) <11ft-

lb> so that the wires will not loosen.

After connection, fasten the cover until it does not turn.

(2) Screw the removed screw plug into the bottom conduit connection.

(3) Insert the cable from the top and connect it.

7.2 Power voltage and load resistance

Make sure the load resistance of the wiring connected to the loop is within the range shown below.

Things convenient to know beforehand

•The unused conduit connection is of great importance to flameproofing and

moisture prevention. So be sure to tighten the flush screw and packing into

the connection.

•When performing an insulation check after wiring, use a Megger (insulation

resistance meter) of 250 V DC or less and avoid applying a high voltage. If an

arrester is equipped, avoid the insulation resistance test and the dielectric

strength measurement.

BUILT-IN ARRESTER

An arrester is used to protect a transmitter or receiver from an abnormal voltage such as lightning

surges induced into signal lines. A built-in type arrester is mounted behind the terminal unit. A

nameplate marked “with arrester” is attached to the terminal unit of transmitter with a built-in

arrester.

Since transmitter and arrester groundings are internally connected together, user have only to

connect the external grounding terminals to ground.

Grounding terminal must be used, in case of the explosionproof or intrinsic safety type

transmitter.

1. Grounding resistance should be 100W or less.

2. Avoid common grounding with a lightning rod.

Important

The built-in arrester should be used in combination with panel mounting type arrester (type PXC)

for distributor protection.

♦Check of arrester

• Measure output current from the transmitter check terminals and output current to flow into

transmitter (see figures below).

When current is measured with an ammeter connected to CK+ and CK- terminals, the

internal resistance 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

not functioning.

• In the above case, the arrester unit (terminal unit) should be replaced with a new one.

♦Limitation of insulation resistance and dielectric strength test

An insulation resistance and dielectric strength test should be avoided as a rule, since it

may damage the arrester.
