u Regulatory Compliance for Radio

and Telecommunication

l FCC Approval

FCC CAUTION

Changes or modications not expressly approved by the party responsible for compliance could

void the user’s authority to operate the equipment.

Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.

This transmitter must not be co-located or operated in conjunction with any other antenna or transmitter.

iii

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment and meets the FCC radio frequency (RF) Exposure Guidelines. This equipment has very low levels of RF energy that it deemed to comply without maximum permissive exposure evaluation (MPE).

l IC Approval

This Class A digital apparatus complies with Canadian ICES003.

Cet appareil numerique de la classe A est conforme a la norme NMB-003 du Canada.

This device complies with Industry Canada’s applicable license-exempt RSSs. Operation is subject to the following two conditions:

(1) this device may not cause interference; and

(2) this device must accept any interference, including interference that may cause undesired

operation of the device.

Le présent appareil est conforme aux CNR d’ Industrie Canada applicables aux appareils radio exempts de licence.

L’exploitation est autorisée aux deux conditions suivantes:

(1) l’appareil ne doit pas produire de brouillage;

(2) l’utilisateur de l’appareil doit accepter tout brouillage radioélectrique subi, même si le

brouillage est susceptible d’en compromettre le fonctionnement.

This equipment complies with IC radiation exposure limits set forth for an uncontrolled environment and meets RSS-102 of the IC radio frequency (RF) Exposure rules. This equipment has very low levels of RF energy that it deemed to comply without maximum permissive exposure evaluation (MPE). [*But it is desirable that it should be installed and operated keeping the radiator at least 20cm or more away from person’s body.]

Cet équipement est conforme aux limites d’exposition aux rayonnements énoncées pour un environnement non contrôlé et respecte les règles d’exposition aux fréquences radioélectriques (RF) CNR-102 de l’IC. Cet équipement émet une énergie RF très faible qui est considérée comme conforme sans évaluation de l’exposition maximale autorisée (MPE).

[*Cependant, il est souhaitable qu’il devrait être installé et utilisé en gardant une distance de 20 cm ou plus entre le radiateur et le corps human.]

1. INTRODUCTION AND GENERAL DESCRIPTION

The FLXA402 can work with the existing analog sensors*1 (pH/ORP, conductivity, inductive conductivity, and dissolved oxygen).

The FLXA402 can additionally work with the SA11 SENCOM sensors to provide measurements with digital sensors and multiple sensor connections 5 sensors.

For the transfer of diagnostic data and other device information to a host system, the FLXA402 supports the HART and MODBUS protocols. This solution also facilitates connection to the cloud

and the construction of an Industrial IoT (IIoT) environment, for improved eld maintenance.

For further information, see GS 12A01F01-01EN.

This manual describes how to use the FLXA402 with Yokogawa’s or other companies’ sensors. Please read carefully this manual and the instruction manuals relevant to those sensors you use before using this instrument.

*1: Analog sensors here represent sensors , PH8E�P, SC4AJ, ISC40GJ, DO30G etc., which are connectable when Model and

Su󰀩x codes -P1, -C1, -C5, -D1 are specied in 1st or 2nd input. However, when Type is “-DD” (NI for FM), -D1 (DO) cannot be

selected.

*2: When -S5 on 1st input is specied, up to 4 pH or SC sensors equipped with SA11 can be connected with a connection to BA11

Junction Box. However, when Type is -DD (NI for FM), -S5 (SENCOM SA) cannot be selected. (1st/2nd input)

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

Make sure the model and su󰀩x code on the nameplate a󰀩xed to the left side of the housing.

Refer to

Apply correct power identied on the nameplate to the unit.
