INTRODUCTION

The FI302 is part of Smar´s first generation of FOUNDATION™ fieldbus field equipment. It is a

converter intended to connect Foundation Fieldbus systems with actuators and positioners for 4 -20

mA control valves. The FI302 produces a 4 -20 mA output proportional to the input received by the

Fieldbus network. Its digital technology enables an easy interface between the field and the control

room, while offering several types of transference functions and interesting features that reduce

installation, operation and maintenance costs.

Foundation Fieldbus is a digital communication system that enables distributing control functions for

field equipment and advantageously replaces conventional technology.

Other protocols only disclose maintenance data, as they were not devised for control data. The main

Fieldbus goal was to overcome this situation. Closed loop control with a 4 -20 mA performance

requires high speed, which means higher power consumption – a feature that is not compatible with

intrinsic safety. This fact led to the use of a moderately high communication speed and to devise a

system with a minimum communication capability. Using scheduling synchronization, the system

controls variable sampling, algorithm execution and communication. The network treatment is

optimized and high circuit loop performance is achieved.

Using Foundation Fieldbus Technology with its capability to interconnect several devices, very large

projects can be constructed. The function block concept allows the user to easily construct the

programming and overview complex control strategies (Smar CD600 users are familiar with this

concept, since it was implemented a few years ago). Another advantage is flexibility, as the control

strategy may be edited without having to rewire or change any hardware.

The FI302 and the Smar FOUNDATION™ fieldbus family have function blocks that avoid the need for

separate equipment and facilitate implementing the control strategy. Among these function blocks,

the following may be enhanced: PID controller, Input Selector, Arithmetic, Signal Characterizer and

Integrator. These built-in blocks improve control, reduce communication, dead-time and costs.

Any FOUNDATION™ fieldbus equipment with Master Backup rapidity may work as a network master

and be locally configured using a magnetic screwdriver in several situations. This tool eliminates the

need for a configurator in many basic applications.

Read carefully these instructions to get the best result from the FI302.

Waiver of responsibility

The contents of this manual abides by the hardware and software used on the current equipmen

version. Eventually there may occur divergencies between this manual and the equipment. The

information from this document are periodically reviewed and the necessary or identified corrections

will be included in the following editions. Suggestions for their improvement are welcome.

Warning

For more objectivity and clarity, this manual does not contain all the detailed information on the

product and, in addition, it does not cover every possible mounting, operation or maintenance

cases.

Before installing and utilizing the equipment, check if the model of the acquired equipment complies

with the technical requirements for the application. This checking is the user’s responsibility.

If the user needs more information, or on the event of specific problems not specified or treated in

this manual, the information should be sought from Smar. Furthermore, the user recognizes that the

contents of this manual by no means modify past or present agreements, confirmation or judicial

relationship, in whole or in part.

All of Smar’s obligation result from the purchasing agreement signed between the parties, which

includes the complete and sole valid warranty term. Contractual clauses related to the warranty are

not limited nor extended by virtue of the technical information contained in this manual.

Only qualified personnel are allowed to participate in the activities of mounting, electrical connection,

startup and maintenance of the equipment. Qualified personnel are understood to be the persons

familiar with the mounting, electrical connection, startup and operation of the equipment or othe

similar apparatus that are technically fit for their work. Smar provides specific training to instruct and

qualify such professionals. However, each country must comply with the local safety procedures,

legal provisions and regulations for the mounting and operation of electrical installations, as well as

with the laws and regulations on classified areas, such as intrinsic safety, explosion proof, increased

safety and instrumented safety systems, among others.

The user is responsible for the incorrect or inadequate handling of equipments run with pneumati

or hydraulic pressure or, still, subject to corrosive, aggressive or combustible products, since thei

utilization may cause severe bodily harm and/or material damages.

The field equipment referred to in this manual, when acquired for classified or hazardous areas, has

its certification void when having its parts replaced or interchanged without functional and approval

tests by Smar or any of Smar authorized dealers, which are the competent companies for certifying

that the equipment in its entirety meets the applicable standards and regulations. The same is true

when converting the equipment of a communication protocol to another. In this case, it is necessar

sending the equipment to Smar or any of its authorized dealer. Moreover, the certificates are

different and the user is responsible for their correct use.

Always respect the instructions provided in the Manual. Smar is not responsible for any losses

and/or damages resulting from the inadequate use of its equipments. It is the user’s responsibility to

know and apply the safety practices in his country.
