INTRODUCTION

The TP302 is from the first generation of Fieldbus devices. It is a transmitter for position

measurements. It can measure displacement or movement of rotary or linear type. The TP302 reads

the position and makes it available to Fieldbus system. The digital technology and communication

provide an easy interface between the field and control room and several interesting features that

considerably reduce the installation, operation and maintenance costs.

The TP302 is part of Smar's complete 302 line of Foundation Fieldbus devices.

Fieldbus is not only a replacement for 4-20 mA or intelligent/smart transmitter protocols. It contains

much more. Fieldbus is a complete system enabling distribution of the control function to 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.

Some of the disadvantages, in comparison to 4-20 mA technology, are communication speed too

low for closed loop control, poor inter-operability between devices of different type and

manufacturer. Others: not possible to pass data direct from one device to another (peer-to-peer

communication).

The main requirement for Fieldbus was 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 minimum

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

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

achieving 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 too 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 and overview complex control strategies. Another advantage is

adding flexibility, the control system may be edited without having to rewire or change the hardware.

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 applications.

The TP302, like the rest of the 302 family, has several Function Blocks built in, like PID controller,

Input Selector and Splitter/Output selector, eliminating the need for a separate device. This takes to

reduced communication and thereby less dead-time and tighter control, not to mention the reduction

in cost.

INSTALLATION

General

NOTE

The installation carried out in hazardous areas should follow the recommendations of Appendix

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.

In warm environments, the transmitter 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 transmitter 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 re-moved; 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 transmitter should be employed.

Although the transmitter is virtually insensitive to vibration, installation close pumps, turbines or

other vibrating equipment should be avoided.

Mounting

The TP302 mounting depends on the type of movement, linear or rotary. Two brackets are required

for mounting, one for the magnet and the other for the transmitter itself.

NOTE

Make sure that arrow engraved on the magnet coincides with the arrow engraved on the Position

Transmitter when the system is in mid travel. When mounting the Position Transmitter, consider

that:

1 . There is no friction between the internal magnet face and the position sensor salience all

over the travel (rotary or linear).

2. A minimum distance of 2 mm to 4 mm distance is recommended between the magnet

external face and the Position Transmitter face.

Should the transmitter installation change, or magnet change, or should any other modification, the

transmitter will require a re-calibration.

IMPORTANT

If the self-diagnostics detect a transmitter failure, for example the loss of the power, the analog

signal will go to 3.9 mA or to 21.0 mA to alert the user (High or low alarm signal is user

selectable).
