INTRODUCTION

The IF302 is a converter mainly intended to interface analog transmitters to a FOUNDATION™

fieldbus network. The IF302 receives up to three current signal typically 4-20 mA or 0-20 mA, and

makes them available to Fieldbus system. The digital technology used in the IF302 enables an easy

interface between the field and the control room and it has several interesting features that reduce

considerably the installation, operation and maintenance costs.

The IF302 is part of SMAR's complete 302 line of FOUNDATION™ fieldbus devices.

FOUNDATION™ fieldbus, is not only a replacement for 4-20 mA or intelligent/smart transmitter

protocols, it contains much more. FOUNDATION™ fieldbus is a complete system enabling distribution

of the control function on equipment in the field.

Some of the advantages of bi-directional digital communications are known from existing smart

transmitter protocols: Higher accuracy, multi-variable access, remote configuration and diagnostics,

and multi-dropping of several devices on a single pair of wires.

Those protocols were not intended to transfer control data, but maintenance information. Therefore

they were slow and not efficient enough to be used as control network.

The main requirements for Fieldbus were to overcome these problems. Closed loop control with

performance like a 4-20 mA system requires higher speed. Since higher speed means higher power

consumption, this clashes with the need for intrinsic safety. Therefore a moderately high

communication speed was selected, and the system was designed to have a minimum of

communication overhead. Using scheduling, the system controls variable sampling, algorithm

execution and communication to optimize the usage of the network, not loosing time. Thus, high

closed loop performance is achieved.

Using Fieldbus technology, with its capability to interconnect several devices, very large control

schemes can be constructed. In order to be user friendly the function block concept was introduced

(users of SMAR CD600 should be familiar with this, since it was implemented several years ago).

The user may now easily build complex control strategies. Another advantage is added flexibility;

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

The IF302, like the rest of the 302 family, has several Function Blocks built in, like PID controller,

Input Selector, Arithmetic, Signal Characterizer and Flow Totalization. These useful blocks eliminate

the need for separate devices and reduce communication and therefore decreasing dead-time and

making the control tighter, not to mention the reduction in cost. Other function blocks are also

available, allowing flexibility in control strategy implementation.

The need for implementation of Fieldbus in small as well as large systems was considered when

developing the entire 302 line of Fieldbus devices. They have the common features of being able to

act as a master on the network and be configured locally using a magnetic tool, eliminating the need

for a configurator or console in many basic applications.

Get the best result of the IF302 by carefully reading these instructions.

This product is protected by US patent number 5,706,007.

INSTALLATION

General

NOTE

The installation carried out in hazardous areas should follow the recommendations of the IEC60079-14

standard.

The overall accuracy of measurement and control depends on several variables. Although the

converter has an outstanding performance, proper installation is essential, in order to maximize its

performance.

Among all factors, which may affect converter accuracy, environmental conditions are the most

difficult to control. There are, however, ways of reducing the effects of temperature, humidity and

vibration.

Locating the converter in areas protected from extreme environmental changes can improve the

converter performance.

In warm environments, the converter should be installed to avoid as much as possible, direct

exposure to the sun. Installation close to lines and vessels subjected to high temperatures should

also be avoided.

Use of sunshades or heat shields to protect the converter from external heat sources should be

considered, if necessary.

Humidity is fatal to electronic circuits. In areas subjected to high relative humidity, the O-rings for the

electronics cover must be correctly placed. Removal of the electronics cover in the field should be

reduced to the minimum necessary, since each time it is removed the circuits are exposed to the

humidity. The electronic circuit is protected by a humidity proof coating, but frequent exposures to

humidity may affect the protection provided. It is also important to keep the covers tightened in

place. Every time they are removed, the threads are exposed to corrosion, since painting cannot

protect these parts. Code-approved sealing methods on conduit entering the converter should be

employed.

Mounting

Using the bracket, the mounting may be done in several positions, as shown on Figure 1.3 -

Dimensional Drawing and Mounting Positions.

For better visibility, the digital indicator may be rotated in steps of 90(See Section 4 - Maintenance

Procedures).

Electric Wiring

Access the wiring block by removing the Electrical Connection Cover. This cover can be locked

closed by the cover locking screw (See Figure 1.1 - Cover Locking). To release the cover, rotate the

locking screw clockwise.

Cable access to wiring connections is obtained by one of the two conduit outlets. Conduit threads

should be sealed by means of code-approved sealing methods. The unused outlet connection

should be plugged accordingly.

Figure 1.2 - Terminal Block

The IF302 uses the 31.25 kbit/s voltage mode option for the physical signaling. All other devices on

the same bus must use the same signaling. 12 to 16 devices can be connected in parallel along the

same pair of wires.

Various types of Fieldbus devices may be connected on the same bus.

The IF302 is powered via the bus. The limit for such devices is 16 for one bus (one segment) for

non-intrinsically safe requirement.

In hazardous area, the number of devices may be limited by intrinsically safe restrictions.

The IF302 is protected against reverse polarity, and can withstand ±35 VDC without damage.
