1.INTRODUCTION AND GENERAL
DESCRIPTION
This manual describes how to use the 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 specifications of the FLXA21, please refer to the General Specifications (GS 12A01A0201E) in the attached CD-ROM.
The FLXA21 2-WireAnalyzer can perform 4 kinds of measurements – pH/ORP (oxidationreduction potential), contacting conductivity (SC), inductive conductivity (ISC) or dissolved oxygen (DO) – with the respective sensor module.
For the pH/ORP measurement, the FLXA21 can be connected to conventional analog pH/ORP sensors, and to Yokogawa’s digital sensor, FU20F pH/ORP SENCOM Sensor with the respective sensor module.
The FLXA21 can perform single or dual sensor measurement. For dual sensor measurement, the combination of two same type sensor inputs – pH/ORP and pH/ORP (analog sensor only),
SC and SC, and DO and DO –are available with two sensor modules.
When using with the pH/ORP SENCOM sensor, please refer to the section 15, 16 and 17 of this
manual for the operation, commissioning and calibration respectively.

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.
• Checking the model and suffix code
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 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.

*1: Use a 2-wire shielded cable with an outside diameter of 6 to 12 mm. *2: Connect the analyzer to gland. (Class D ground: 100 ohm or less)
The way of connecting the grounding cable varies depending on the plastic housing and stainless steel housing.
In the case of the plastic housing, connect the grounding cable to the terminal of the power module inside, and in the case of the stainless steel housing, connect the grounding cable to the terminal of the housing. Use a cable with an outside diameter of 3.4 to 7 mm for the grounding line of the plastic housing.
The minimum cross sectional area of the protective grounding cable should be 0.75 mm2. *3: This line is connected to a distributor or 24V DC power supply.
*4: Terminal numbers for each sensor module are shown below.
*5: Two modules of the same kind of measurement/sensor type can be installed. When measuring inductive conductivity or pH/ORP with the SENCOM sensor, only one module can be installed.
*6: The terminal box may be necessary depending on the sensor cable length and the distance between the analyzer and the sensor.
The SENCOM sensor is to be connected directly to the analyzer without a terminal box. *7: Two outputs, output 1 and output2, of PH201G or SDBT are same signals.

<2. WIRING AND INSTALLATION> |
2-2 |
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 the pH sensor is used, the cable length including the sensor cable should not exceed 20 meters (65.6 feet). 60 meters when using BA10 extension box and WF10 cable.
Select an installation site where the ambient temperature and humidity are within the limits of the instrument specifications (see chapter 2). If the instrument is installed outside and exposed to direct sunlight, a sun shade hood should be used.
Ambient Operating Temperature: -20 to +55 ºC
Storage Temperature: |
-30 to +70 ºC |
Humidity: |
10 to 95% RH (Non-condensing) |
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
Before installing this instrument, open the front panel and remove the wiring covers, and then
install the cable glands.
Remove all the wiring covers. They are fixed at the places marked with ○ (circle) and (triangle)
in Figure 2.2. Be careful not to damage the pawls when removing the covers.
NOTE
Be careful not to lose the wiring cover screws.
