Safety hints

Correct use

•The field transmitter displays scaled signals from thermometers and thermocouples

to a loop powered output. The optional display indicates the measurement regarding

the real temperature in the process.

•The manufacturer cannot be held responsible for damage caused by incorrect use

of the instrument. Changes must not be made to the unit.

•The unit has been designed for use in industrial areas and must only be used in an

installed condition.

•The process display is manufactured using state of the art technology and complies

to the directives. On the version for use in explosion hazardous areas the norms

EN 50014, EN 50020 are also complied with.

The unit could become dangerous if it is incorrectly installed or used.

Therefore please take note of all the safety hints and pictograms shown in these

installation and operating instructions. The meanings of the pictograms are:

"Note" means activities or sequences that, if not done correctly could

have an indirect influence on the units operation or could release an

unforeseen unit reaction.

"Caution" means activities or sequences that, if not done correctly

could lead to personal injury or faulty unit operation.

"Warning" means activities or sequences that, if not done correctly

could lead to serious personal injury, to a safety risk or total damage

to the unit.

Installation, initial setting up and operating personnel

•Mechanical and electrical installation, setting up and maintenance of the unit must

only be carried out by skilled and qualified personnel who have been authorised to

do so by the plant operator. The skilled personnel must have read and understood

these installation and operating instructions. They must follow them carefully.

•The unit must only be operated by trained personnel who have been authorised by

the plant operator. They must follow all instructions contained in this manual.

•Always make sure that the unit is correctly connected following the electrical

connection diagrams. When removing the unit cover the electrical contact protection

is lost (danger of electrical shock). The housing must only be opened by qualified

skilled personnel.

•The unit must only be used in an installed condition.

Repairs

Repairs must only be carried out by trained customer service personnel. If the unit is

to be returned to Endress+Hauser for repair, please include a description of the fault.

Technical advancement

The manufacturer reserves the right to improve and update the technical details.

1. System description

The smartgrad TMD833 is a microprocessor based 2 wire smart field transmitter for

temperature measurement. The transmitter and the optional LC Display are

encapsulated into IP 65 housing.

The instrument converts a resistance bulb change or a thermocouple generated mV

signal into process information (typical 4-20mA).

Otherwise generated Ohm or mV signals are also accepted as input signals.

The smartgrad TMD833 Field - Transmitter accepts one of the following inputs with a

single set of electronics:

•3 different RTD types

•10 different Thermocouple types

•Ohm, two different ranges

•mV

The smartgrad TMD833 is available as General Purpose, Intrinsically Safe or Explosion

proof design (Pending). Generally the input is galvanically isolated from the output;

another guarantee for high operational reliability.

2. Mechanical installation

,QVWDOODWLRQKLQWV

•The unit must be operated in an installed condition.

•The permissible operating ambient temperature is -40...+85°C (for the EEx ia version

please respect the temperature class in the certification).

•Protect the unit from heat sources.

Normally the installation requirements for both Ex and non-Ex units are the same.

The operator has to follow the rules regarding the specific Ex area class.

2.1 Mounting

TMD833 can be 2" pipe or wall mounted.

Please find the brackets for 2" pipe or wall

mounting inside the carton box.

C99MT004.CDR

3. Electrical connection

3.1 Terminal layout and power supply

The smartgrad TMD833 field transmitter utilises the standard 4...20 mA signal for

temperature, ohm or mV linear output.

The analogue output signal is available both for direct 4...20 mA or reverse 20...4 mA.

HART Protocol is superimposed onto the two wire loop powered output signal.

If self-diagnostics detect a sensor burnout or transmitter failure, the analogue signal

will be driven either below 3.8 mA or above 21 mA to alert the user. High or low failure

mode signal is user-selectable by software (Commuwin II or DXR275).

Grounding

•TMD833 EEx ia Version - CESI EX-99.E.003X

6SHFLDOFRQGLWLRQVIRUVDIHXVH;

The temperature transmitter TMD833 (EEx ia version) shall be supplied by associated

apparatus with galvanic insulation certified according to EN 50.014 / 50.020

standards, type of protection EEx ia, with the electrical characteristics indicated in the

certification.

In flammable atmosphere the electrical characteristics on the power / loop side and

also on the sensor side must correspond to the certification.

3.2 Grounding of the loop circuit

Both the terminal layout and the connection values of the field transmitter relate to the

Ex version. The unit is only meant for use in a 4 ... 20 mA current loop circuit.

Potential equilibrium must be garanteed on the current loop (inside and outside the

Ex hazardous area). In order to achieve this use the earthing (ground) lug on the

housing.

Integration with HART Multiplexer in generic Fieldbus system. Direct reading of the

process variable with Digital accuracy.

4. Operating overview

Operation as well as the parameter settings and their function are exactly the same as

General Purpose - EEx ia or EEx d - Version of smartgrad TMD833 field transmitter.

Please note the following paragraphs for operation and the notes for setting up.

4.1 Configuration

The complete configuration of smartgrad TMD833 field transmitter can be made

remotely with HART protocol. The digital communication is superimposed on the

4 ... 20 mA output signal and transmits condition information during the operation

without disturbing the measurement value.

Commuwin II Commubox - Interface FXA191*

1RWH

HART Communication requires a minimum loop

resistance of 250 Ohms. Do not communicate with

the instrument when power is below 13 V DC at the

transmitter terminals.

With the same connection it is also possible

to use the E+H interface Commubox FXA191

instead of the hand held module !
