CAUTION :
Rotating the upper assembly part :
The upper assembly (housing and electronic unit) can not be rotated by 90° left or right just by
removing the 2 hexagonal socket bolts (M6 x 12)
If the assembly parts must be turned over than 90°, or if
the position is already amended since the delevery by Fuji,
it's necessary to remove the electronic unit from the
housing and disconnect the flat-cable from the electronic
measuring cell before turn the housing.
If necessary, amend the flatcable's position connecting
electronic unit and measuring cell, after fit the different
parts.
Failure to observe this may lead to the deterioration of the
flat cable, which is not covered by the manufacturer's
warranty.

The FCX-AII series transmitter accurately measures the differential pressure, level liquid, gauge
pressure or flow rate, and transmits a proportional current signal of 4 to 20mA DC.
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
FXW communicator (Hand Held Communicator).
The transmitter utilizes a unique micromachined capacitive silicon sensor with state-of-the-art
microprocessor technology to provide exceptional performance and functionnality.
The transmitter is compact and light, provide high accuracy and reliability.
Local adjustment of zero and span are possible from outside screw on the electronic housing.
Measuring principle
The operating principle of the FCX-AII 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 trans-
mission unit, and is then output as a current of 4 to 20mA DC

After adjustment of the transmitter, it should be kept energized for about 10
seconds to write the adjustment results into memory.
The zero point check or zero adjustment in flameproof area, is only possible by the outside screw
on the electronics housing without opening the covers of this housing and in case of adjustment
via HHC, the local wiring (connection) is not allowed.
Turn on the power to the transmitter.
Check the output signal of the transmitter by connecting a DC ammeter across CK+ and CK– of
the terminal block.
After ten minutes or longer, adjust the transmitter output current at 4 mA (zero adjustment).
(See below)
START UP AND SHUTDOWN
3
3.1 Installation :
After installation (refer to chapter 6.1) and before start up of the transmitter, be sure to perform
the following checks and procedures.
Preparation :
(1) Check for liquid or gas leakage of the process connection by ap-
plying soapy water or similare.
(2) Check of the electrical connection according to the “Terminal block
connection diagram” shown in chapter 7.1.
(3) Vent the process covers of the transmitter.
Before starting up the transmitter in flameproof area, please read carre fully
the technical instruction note ATEX Ref.HD FCX AII 002 .
The compatibility of process with the transmitter, has to be checked and ensured by skilled
people from customer side.
(4) Perform zero point adjustment.
Zero point check
Zero adjustment :
Adjustment by zero adjustment screw
Zero adjustment is possible from outside screw on electronic hou-
sing.
Adjust zero point of the transmitter to 4 mA by turning the zero ad-
justment screw.
The higher you turn the screw, the quicker is the change of the
zero.
After all operations are finished, assemble and tight the covers of the electronics housing.
(Tightening torque: 20 N.m).
When the plant requires chemical cleaning at the start up operation, be
sure to close the isolating valves of the transmitter to avoid that cleaning
liquid or particules are introduced to the transmitter wetted parts.

Field device
To operate the FCX-AII series transmitter, the FXW communicator is used for each adjustment.
4.1 Adjustment with the FXW communicator (HHC)
The span adjustment of the transmitter can be done by using the FXW communicator without
applying a reference pressure. Here after you will find the wiring of the FXW to modify the
transmitter parameters. For the use and the start up of the communicator, please refer to the
instructions of the FXW (HHC).
Remarks :
* The HHC must be on [OFF] position during the connection.
It can't be connected to the terminals CK+ and CK- of the terminal block of the transmitter.
* The HHC has no polarity. (You can connect either the red or black electrical wire to the ter-
minals +or -of the transmitter or on the wires of the loop).
HHC = Hand Held Communicator
4.1.1 Connection of HHC
The HHC can be connected in any point of the loop.
To communicate with the HHC, a load resistor of 250mini is required.
Refer the following diagram connection of the HHC.
ADJUSTMENT
4
After adjustment of the transmitter, it should be kept energized for about 10
seconds to write the adjustment results into memory.
In the case of a flameproof transmitter, the HHC can only be connected
via the junction box located outside the hazardous area.
DANGER
In the case of a flameproof transmitter, never connect the FXW to the ter-
minal block of the transmitter in hazardous area installations.

4.1.2 Start up of the HHC
• Put on/off switch of the HHC on “ON” position.
Put on the enclosed “key” in the corresponding location of the HHC. Without the key and
with the key in vertical position, you can just read the transmitter parameters.
To write new parameters in the transmitter, the key needs to be in horizontal position.
Otherwise, you will have an inscription on the HHC screen "INHIBIT KEY OK ?" to let you
know that the key needs to be turned to enable the programming of new parameters in the
transmitter.
NOTA : "INHIBIT KEY" means that the key permits or inhibits (prohibited) writing parame-
ters in the transmitter
• The transmitter version and the revision of the HHC software are indicated on the screen during
the start up.
After around 4 seconds the inscription "PUSH MENU KEY" appears (please push menu key)
HHC with the optional printer will have the inscription "PAPER FEED". Please push on <INC>
key. By pushing on <INC> key the paper feed is activated.
"PUSH MENU KEY" will be indicated on the screen by if you push on the clear <CL> key.
On the screen appears the inscription "RECEIVING START". The HHC reads out the data from
the transmitter, and switches automatically in the first programming menu : TAG menu.
In case of a connection problem, "NO CONNECTION" will appear on the screen. The "PUSH
MENU KEY" appears again if you push the clear <CL> key.
The reasons of a communication problem can be :
- The 4-20 mA output is not powered.
- The 4-20 mA is disconnected.
- The connection between the amplifier unit and the measuring cell is wrong.
- The loop resistance value doesn't correspond to the required one depending on the power
supply.
- The HHC is not connected to the correct terminals
Configuration menus of the FXW communicator
The configuration is based on different menus. The identification of the following program
steps are indicated on the bottom line of the screen inside following signs ( < > ).
The configuration menues are selectable by pushing on the INC (increase : configuration
N+1), or the DEC (decrease : configuration N-1), keys. The most important menus can be
selected with a specific, corresponding key.
The <CHNG> (CHANGE, modification) key inside each menu gives the possibility to make
modifications or to program new parameters in the transmitter with the alphanumeric keys.
To program letters, you first need to push the <ALHA> key, each time before programming
the letter. To add a space between caracters, you have to push the keys <ALHA>, and <
>. To delete caracters, please use the clear key <CL>.
When the modification is programmed, you have to push the enter key <ENT> to send the
new information to the transmitter. For safety reasons, you need to confirm the modification
a second time by replying on the question "CHNG OK ?" . You confirm by typing a second
time on the enter < ENT> to confirm.
At this moment the new programmed information are written in the transmitter memory,
"WRITE" indication will appear on the screen of the FXW

18
The following shows the flow of 21 key operations (n° 1 to L), explained for FXW version 7.0
(FXW 1-A4).
FXW prior to Version 7.0 are not available of operation of FCX-AII series transmitter. In this case,
the user is requested to contact our office for ROM version up.
