INTRODUCTION

The TT301 is a transmitter mainly intended for measurement of temperature using RTDs or

thermocouples, but can also accept other sensors with resistance or mV output such as:

pyrometers, load cells, resistance position indicators, etc. The digital technology used in the TT301

enables the choice of several output functions, an easy interface between the field and the control

room and several interesting features that reduce considerably the installation, operation and

maintenance costs.

The TT301, besides the normal functions offered by other smart transmitters, offers the following

functions:

SPECIAL SENSOR: the output follows a mV or Ohm input according to a 16-point linearization

table.

PID OUTPUT CHARACTERIZATION: the PID output signal (MV) follows a curve determined by 16

points.

BACKUP SENSOR: the process measurement is realized by two sensors, but only one supplies the

temperature. If it failure the other take its place.

INPUT SELECTOR: the selection between two sensor to obtain the measure is configured by user

based in the conditions of maximum, minimum or average temperature of the sensor.

CONTROLLER: the process variable is compared to a setpoint. The deviation acts on the output

signal according to a PID algorithm (Optional).

BATCH : setpoint generator allowing pre-programmed recipes of up to 2-week duration in 16 points.

LOCAL ADJUST: allow to set lower and upper value, sensor type, operation mode, indication,

setpoint, PID parameters without a configurator.

PASSWORD : three configurable levels for different functions.

CHANGE COUNTER: indicates the number of changes in each functions.

SPECIAL- SENSOR-UNIT: allows the reading to be indicated by one of 100 standard engineering

units or any special unit with up to 5 characters.

Get the best results of the TT301 by carefully reading these instructions.

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 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

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

INSTALLATION

General

The overall accuracy of temperature and other measurements depends on severalvariables.Although

the transmitter has an outstanding performance, proper installation is essential,in orderto maximizeits

performance.

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

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

vibration.

Mounting

Temperature fluctuation effects can be minimized bylocatingthe transmitterin areas protected from ex-

treme environmental changes.

In warm environments, the transmitter should be installed to avoid, as much as possible, direct expo-

sure to the sun. Installation close to lines and vessels subjected to high temperatures should also be

avoided. For temperature measurements, sensors with cooling-neck can be used or the sensor can be

mounted separated from the transmitter housing.

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

considered, if necessary.

The transmitter may be mounted in two basic ways, as follows:

Separated from the sensor, using optional mounting brackets;

Mounted on the sensor assembly.

Using the brackets, the mounting may be done in several positions, as shown on Figure 1.1.

Measurement error can be decreased by using proper wires (see Section II, Operation).

WARNING

Do not remove the graphite grease from the covers, or they may jam.

Electronic Housing

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. Everytimethey

are removed, the threads are exposed to corrosion, since painting cannot protect these parts. Sealing

methods should be employed on conduit entering the transmitter.

One of the conduit inlets for electrical connection is used to mount the sensor integral to the

temperature transmitter (see Fig. 1.1).

WARNING

The unused cable entries should be plugged and sealed accordingly to avoid humidity entering,

which can cause the loss of the product’s warranty.

For better visibility, the digital indicator may be rotated in steps of 90o(see Section 5, Maintenance).

Reach the display and main board by removing the Cover with window. This cover should be locked

closed by the cover locking screw. To release the cover, rotate the locking screw clockwise. Seefigure

Wiring

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

by the cover locking screw (Figure 1.2- b). To release the cover, rotate the locking screw clockwise.

The terminals in the superior part marked with () and (−) are to receive the powering from 12 to 45

Vdc. The inferior terminals marked with the numbers from 1 to 4 they are for the connections of the

different types of sensor.

Test and Communication terminals allow, respectively, to measure the current in the 4 - 20 mA loop,

without opening it, and to communicate with the transmitter. To measure it, connect a multimeterin the

mA scale in the "" and "" TEST terminals. To communicate with it, use a HART configurator

between "" and "" COMM terminals. The wiring block has screws on which terminals type fork or

ring can be fastened, see Figure. 1.3.
