Wiring and Installation
Open the cover and remove the plastic inserts covering the modules. They will be reinstalled
after the wiring is completed.
1.1
Installation site
The FLXA21 is weatherproof and can be installed both inside and outside. It should, however, be
installed as close as possible to the sensor to avoid long cable runs between the instrument and
sensor. When a pH sensor is used, the cable length including the sensor cable should not exceed
20 meters (65.6 feet); 60 meters (197 feet) when using BA10 extension box and WF10 cable.
For a conductivity sensor the cable run should not exceed 60 meters (197 feet). For dissolved
oxygen the sensor cable run should not exceed 30 meters (100 feet). For SENCOM pH/ORP the
sensor cable run should not exceed 20 meters (65.6 feet).
Select an installation site that meets the following conditions.
• Mechanical vibrations and shocks are negligible
• No relay switch and power switch are installed close to the converter
• There is space for cable connection beneath the cable glands
• Not exposed to direct sunlight or severe weather conditions
• Maintenance is possible
• No corrosive atmosphere
• Ambient Operating Temperature: -20 to +55 °C
Humidity: 10 to 95% RH (Non-condensing)
• Water Protection: IP66 (except Canada), Type 4X (except Canada), Type 3S/4X (Canada)
Select an installation site where the ambient temperature and humidity are within the limits of the
instrument specifications (see chapter 2.1 in the instruction manual). If the instrument is installed
outside and exposed to direct sunlight, a sun shade hood should be used.
The FLXA21 can be mounted on a wall, pipe or panel when the mounting kit is ordered *this
is how we will keep the unit in stock*. For dimensional information please refer to section 3.6
Mounting Methods in the instruction manual.

Wiring the power supply
FLXA21 is a 2-wire transmitter and can be powered by a DC power supply of max. 40 VDC. The
Power Supply voltage depends on:
• The load resistance: impedance of electronic equipment: typically 250 Ohm
• Number of input modules: 1-sensor measurement or 2-sensor measurement.
One (1) Sensor module (1 input):
16 to 40 V DC (for pH/ORP, SC and DO)
17 to 40 V DC (for ISC)
21 to 40 V DC (SENCOM pH/ORP)
Two (2) Sensor modules (2 inputs):
22.8 to 40 V DC (for pH/ORP, SC and DO)

Wiring the sensor
The FLXA21 can be used with a wide range of commercially available sensor types, both from
Yokogawa and other manufacturers. For more detailed information, refer to the respective
instruction manual of the sensor. The sensor systems from Yokogawa fall into two categories; the
ones that use a fixed cable and the ones with separate cables.
To connect sensors with fixed cables, simply match the terminal numbers in the instrument
with the identification numbers on the cable ends. The separate sensors and cables are not
numbered, but instead use a color-coding system.
1.3.1
pH Measurement
Conventional pH sensors are connected to the module as follows:
FLXA21
11 Temperature
12 Temperature
13 Reference
14 Solution ground
15 Glass (measure)
16 Shield
Jumper

17 Shield
TC
REF Liquid PH
Earth
In addition to the wiring of the sensor, insure that a jumper for low-impedance sensor inputs is
installed. The jumpers can be found on the plastic sensor module cover and can be stored in the
lower level module wiring cover.
• pH Glass Electrode is a high impedance sensor input
• Special electrodes using 2 glass sensor (example: Pfaudler, SC24V) do not need jumpers.
Terminals 15-16 are identified as input 1 (High Impedance) and terminals 13-17 are defined as
input 2 (Low Impedance). For conventional pH sensors, the jumper is placed as illustrated:

ORP Measurement
The ORP measurement uses the same sensor input module as the pH measurement. It is not
uncommon to measure ORP as process variable and a pH Glass electrode as reference. This is
the case with rH measurement and with pH compensated ORP measurement.
Standard reference electrodes and an ORP/REDOX electrode are low impedance sensor inputs
Conventional ORP sensors are connected to the module as follows:

<1. Wiring and Installation>
NOTE
When two sensor modules are used, the upper-level module is for input 1 and the lower-level
module is for input 2. For ease of installation, first wire input 2 sensor on the lower-level module
(A), and attach the wiring cover; then wire input 1 sensor on the upper-level module (B) and
replace the module wiring cover (C).
(A)
(B)
(C)
When all wiring is completed and all covers have been installed, the front cover can be closed
and the power can be switched on.
WARNING
When one of the modules has been removed and replaced, make sure you lock the module
securely in place. Confirm that all locking-tabs (including for BLANK slots) are in “Locked”
position before you close the front panel. If the locking-tabs are in “Unlock” position, the front
panel may be interfered with locking-tabs.
Unlock
Lock
WARNING
Do not tighten up four front panel screws one by one.
Each front panel screw should be tightened up in two times of screwing. And, firstly the screw
at the upper left should be screwed a bit, the next is at the lower right, third is at the upper right,
and fourth is at the lower left. The second round is the same sequence again to tighten up four
screws.
Do not use an electric screwdriver with high revolutions. If an electric screwdriver is used for
these front panel screws, the revolutions of the electric screwdriver should be less than 400 rpm.
Four screws should be tightened to the following torque;
0.8 to 0.9 N•m (for the plastic housing)
1.5 to 1.6 N•m (for the stainless steel housing)

NOTE
The special grommet is intended to be used to seal the multiple cables from the Yokogawa flow
fittings such as FF20.
The designated cables are WU20 sensor cables, which are approximately 5 mm (0.2”) in
diameter, and K1500FV liquid earth cables, which are approximately 2.5 mm (0.1”) in diameter.
For sensor systems using a single cable, like the FU20/FU24 and the PR10, PD20, PF20 and
PS20, the standard gland will accommodate the cable adequately. Single cables between
approximately 6 mm and 12 mm (0.24” and 0.47”) can be sealed properly with these glands and

When all wiring is completed, turn on the power to the instrument. Make sure that the LCD
screen turns on, and then wait for the Quick Setup menu to be displayed. Follow the on-screen
instructions for set-up and calibration. If the instrument is not configured correctly an error
indicator may be displayed, or the measurement values displayed may be incorrect. Consult the
Instruction Manual supplied on CD with the analyzer, and check the initial settings and change
them to suit your purpose.
Basic operation of the software is similar the EXAxt 450 series. For more detailed information
please refer to the instruction manual.

a. pH measurement module
Under “measurement “a selection is made for pH, ORP or pH&ORP. The selected
measurement must be in accordance with the sensor wiring. When rH measurement is
requested pH&ORP must be chosen on this level. The rH must then be selected in the
commissioning menu.
b. SC measurement module
Under “measurement” a selection is made between Conductivity, Resistivity, Concentration
or Concentration plus Conductivity. On this level only Conductivity or Resistivity can be
selected. Settings for Concentration measurement must be done in the commissioning
menu.
c. DO measurement module
Under “sensor type” a selection is made for Galvanic or Polarographic. The selected sensor
type must be in accordance with the sensor wiring. Otherwise the analyzer or sensor can be
damaged.

4.Maintenance
n Periodic maintenance
The FLXA21 requires very little periodic maintenance, except to make sure the front window
is kept clean in order to permit a clear view of the display and allow proper operation of the
touchscreen. If the window becomes soiled, clean it using a soft damp cloth or soft tissue.
To deal with more stubborn stains, a neutral detergent may be used.
When you must open the front cover and/or glands, make sure that the seals are clean and
correctly fitted when the unit is re-assembled in order to maintain the housing’s weatherproof
integrity against water and water vapor.
The pH measurement uses high impedance sensors and may otherwise be prone to problems
caused by exposure of the circuitry to condensation.
CAUTION
Never use harsh chemicals or solvents. In the event that the window does become heavily
stained or scratched, refer to the parts list for replacement part numbers.
