1. INTRODUCTION AND GENERAL
DESCRIPTION
This manual describes how to use the FLXA202/FLXA21 with Yokogawa’s or other companies’
sensors. Please read carefully this manual and the instruction manual of the relevant sensor
before using this instrument.
ForthespecicationsoftheFLXA202/FLXA21,pleaserefertotheGeneralSpecications.(GS
12A01A03-01EN, GS 12A01A02-01E)
The FLXA202/FLXA21 2-Wire Analyzer can perform 4 kinds of measurements – pH/ORP
(oxidation-reduction potential), contacting conductivity (SC), inductive conductivity (ISC) or
dissolved oxygen (DO) – with the respective sensor module.
Up to two analog sensors can be connected. (pH/ORP, SC, ISC)
For dual sensor measurement, the combination of two same type analog sensor inputs – pH/
ORP and pH/ORP, SC and SC, and DO and DO – are available with two sensor modules.
In additin to conventional analog connections, digital sensor measurement using SA11 SENCOM
Smart Adapter is available.

1.1 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o󰀩ce.
n Checking the model and su󰀩x code
lFLXA202
Makesurethemodelandsu󰀩xcodeonthenameplatea󰀩xedtotheleftsideofthehousing.
Refer to 1.5 Model&Su󰀩xCodes
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 1.3 Example of nameplate (FLXA202)
lFLXA21
Loosen four front panel screws of the FLXA21, open the panel to the left, and make sure the
modelandsu󰀩xcodeonthenameplatea󰀩xedtotheleftsideorinsideofthehousingagrees
with your order.Refer to 1.5 Model&Su󰀩xCodes
CAUTION
When you open the front panel, make sure the screws are completely out of the screw holes, and
then open the front panel slowly in order not to damage the threaded parts on the housing. If the
threaded parts are damaged and the screws cannot be tightened, the waterproof performance
will deteriorate.
NOTE
Be careful not to lose the four front panel screws.

Equipment with “Category I” (ex. two-wire transmitter) is used for connection to circuits in which measures are taken
to limit transient over-voltages to an appropriately low level.
Note 2: Pollution degree indicates the degree of existence of solid, liquid, gas or other inclusions which may reduce
dielectric strength. Degree 2 is the normal indoor environment.
