SMAR TP290 Manuale

Introduction

III

INTRODUCTION

The TP290 is from the well-know family of SMAR’s devices. It is a transmitter for position

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

digital technology provide an easy interface between the field and control room and several

interesting features that considerably reduce the installation, operation and maintenance

costs.

The TP290 is versatile and reliable, and has very high accuracy. It may be used for control

valve stem position measurement, or in any other position sensing application such as

louvers, dampers, crushers, etc.

The TP290 is very versatile, users can standardize one position indicator for all different

kinds of control valves and other machines, keeping spares and training to a minimum.

The TP290, besides the normal function of position measurement and 4-20mA output

generation, offers the following functions:

Linear or Rotary Travel type;

0.1% F.S.;

Position Calibration (4 and 20 mA points) via Local Adjustment or Remote Calibration via

Hand Held Terminal;

Non contact position sensing;

Optional LCD indicator;

Diagnostics and Configuration via adjust local.

Get the best results of the TP290 by carefully reading these instructions.

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 other

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 pneumatic

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

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 necessary

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.

1.1

INSTALLATION

General

NOTE

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

NOTE

See appendix “A” Hazardous Area Certifications.

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 sun shades 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 these parts cannot be protected

by painting. 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 TP290 mounting depends on the type 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 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 of 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).

Linear Movement

Install the magnet on the valve stem using the magnet mounting bracket.

The linear magnet movement must be orthogonal in relation to the main axis of the position

transmitter. For example, if the linear magnet movement is vertical, the transmitter main axis must

be horizontal, as show in Figure 1.3.
