Instrument Check
Upon delivery, unpack the instrument carefully and inspect it to ensure that it was not damaged
during shipment. If damage is found, retain the original packing materials (including the outer
box) and then immediately notify the carrier and the relevant Yokogawa sales office.
n Checking the model and suffix code
l FLXA202
Make sure the model and suffix code on the nameplate affixed to the left side of the housing.
NOTE
Be sure to apply correct power to the unit , as detailed on the nameplate.
-D-B-D-AB-P1-P1
-A-N-LA-N-N/U/H6
Figure 1.1
Inside of the FLXA202 and example of nameplate
l FLXA21
Loosen four front panel screws of the FLXA21, open the panel to the left, and make sure the
model and suffix code on the nameplate affixed to the back side of the front panel agrees with
your order.
CAUTION
When you open the front panel, make sure the screws are completely out of the screw holes, and

to the Appendix A1). The wiring covers will be re-installed after the wiring is completed.
2.1
Installation site
The FLXA202/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 90% RH at 40 °C (Non-condensing)
• Water Protection: IP66 (except Canada), NEMA 4X (except Canada), Type 3S/4X (Canada)
If the instrument is installed outside and exposed to direct sunlight, a sun shade hood should be
used.
The FLXA202/FLXA21 can be mounted on a wall, pipe or panel when the mounting kit is
ordered. For dimensional information please refer to the Appendix, Mounting methods.
2.2

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
• Standard reference electrodes and an ORP/REDOX electrode are low impedance sensor
inputs
• 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:

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
the standard tule.

3. Operation
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
User’s 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 User’s Manual of the FLXA202/FLXA21.

Commissioning
NOTES for Quick Setup:
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.

<5. Maintenance>
5. Maintenance
n Periodic maintenance
The FLXA202/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.
