GENERAL

The TX200H is a registered HART 7 compliant device. It is a highly accurate,

rugged, SMART pressure transmitter that can communicate digitally and via

the 4-20 mA analog signal output. The TX200H utilizes the HART protocol

and an internal microcontroller to allow the end-user to easily configure and

calibrate the pressure transmitter as it provides process variable measure-

ment and device health data.

HART is an acronym for Highway Addressable Remote Transducer and it has

become the most widely adopted standard for industrial communication. The

Hart protocol is based on a standardized set of commands that is maintained

by the HART Communication Foundation (HCF) and allows any end-user to

easily integrate devices like the TX200H into their HART enabled system. The

TX200H, as a registered HART device has been designed to communicate

with other HART enabled devices such as a software package running on a

PC with HART interface or a field portable HART communicator.

WIRING

No special or separate wiring is required for digital communication with HART

devices since the HART FSK (Frequency Shift Keying) signal is superimposed

on top of the 4-20 mA output signal. Digital data is sent to and from the field

device via a HART master while real-time process information is available via

the 4-20 mA signal. It is recommended that a high quality twisted pair or

shielded wire cable be used where extended lengths are required or electrical

noise may be present.

NOTE: The TX200H is reverse bias protected so no damage will result in

the event of accidental reversal of power leads.

DISCONNECT ALL SUPPLY CIRCUITS BEFORE WIRING UNIT. ELECTRICAL

RATINGS STATED IN LITERATURE AND ON THE TRANSMITTER MUST

NOT BE EXCEEDED.

WIRE IN ACCORDANCE WITH LOCAL AND NATIONAL ELECTRICAL

CODES. THROUGH PROPER INSTALLATION, THE WIRES SHALL BE

PROTECTED AGAINST MECHANICAL DAMAGE, I.E. BY USE OF A

CONDUIT.

THE TX200H TRANSMITTER ACCEPTS A SUPPLY VOLTAGE OF 10-36

VDC AND SHALL NOT EXCEED 36 VDC. THE SUPPLY VOLTAGE MUST

BE ISOLATED FROM MAINS VOLTAGE BY DOUBLE/REINFORCED

INSULATION.

EARTH GROUND MUST ALWAYS BE CONNECTED TO THE GREEN WIRE

TO PROVIDE SHIELDING AND ELECTRICAL SAFETY.

THE TX200H WIRING MUST BE INSTALLED IN A GROUNDED METAL

CONDUIT OR WITH OTHER SUITABLE SHIELDING IN ORDER TO MEET

EUROPEAN EMC DIRECTIVE REQUIREMENTS.

ATEX REQUIREMENTS ONLY

THE WIRING TO THE PRESSURE SENSOR MUST ONLY BE CONNECTED

IN THE SAFE AREA OR BY AN APPROVED TERMINAL BOX CERTIFIED

TO EN 60079-0:2012, EN 60079-1:2007, EN 60079-31:2009 FOR

HAZARDOUS LOCATIONS.

EXTERNAL GROUNDING SCREW (OPTION M460) IS REQUIRED FOR

NON-METALLIC CONDUIT SYSTEMS (SEE FIGURE 1).

A 1/2” NPT (male) or M20 conduit connection is provided on the top of the

transmitter with 18 AWG, 72” length lead-wires. An external grounding screw

and clamp is provided when selecting option M460 (see figure 1). The lead-

wires are color coded as follows:

Red: +signal

Black: - signal

Green: Earth ground

Bench Operation:

To operate the TX200H on the bench, it must be connected to a power supply

and a load resistor (see Figure 2). The HART master (e.g., handheld com-

municator) may also be connected directly across the red and black wires at

the TX200H. A voltmeter across the 250 Ω resistor can be used to measure

the current in the loop ( Iloop = Vresistor / 250 ). At 4mA the voltmeter will

read 1 volt and at 20 mA the meter will read 5 volts.

Field Operation:

The TX200H can be connected to any HART compatible input card or module

or any standard 4-20mA input if the HART interface is not being used. In

most cases the power supply and the load resistor are built into the input

card or module (see Figure 3).

Power Supply/Load Limits:

For general operation of the TX200H while using HART the series loop resis-

tance should be between 230 to 600 ohms and the power supply voltage

should be 24V nominal.

The TX200H can be operated without the HART interface within the operating

limits of the power supply and loop resistance as shown in Figure 4.

Fault Currents:

Under normal operating conditions the analog output signal of the TX200H

will remain between 4-20mA. In the event that the pressure goes beyond

the operating range of the device or in a fault condition, the TX200H will indi-

cate the condition on the 4-20mA loop as follows:

Re-Ranging: Using the HART interface, the range of the TX200H can be

modified. This is useful in situations where the exact range transmitter is not

available. Re-Ranging is accomplished by changing the lower range value

and the upper range value to achieve the desired range. There are limita-

tions on the range adjustment. The lower/upper range limits must be within

the upper and lower sensor range (as marked on the transmitter body and

within the certificate of calibration) and the span must be greater that the

process variable (PV) minimum span programmed in the device. The PV min.

span is 10% of the range of the device for models with a pressure range of

≥ 100 psi and 20% of the range of the device for models with a pressure

range < 100 psi.

For example, a 1000 psi transmitter can be re-ranged to be a 100

psi transmitter.

Multi-Drop Mode: Using HART communication it is possible to connect

up to 15 field devices to a HART master over a single pair of wires. In this

topology (see Figure 5) the field device is placed in a fixed current mode and

all communication occurs over the HART interface. Each device is assigned a

unique poll address (1-15). This serves as a unique address so that the

master can access the field devices individually. NOTE: The TX200H ships

from UE with the poll address set to O. A poll address of 0 indicates the

device is not in multi-drop mode.

Part II - Set-Up

Tools Needed

HART Communicator or other Master

Using a HART handheld communicator, or other HART master,

you can access the many features of the TX200H.

Read Device Information: you can read information such as the model

number and revision, the device I.D. and the range of the sensor.

Device Setup: can be used to setup or commission a device prior to placing

it in service. These features allow the user to write things like a device tag

and a device description into the TX200H so that it can be uniquely identified

over the HART interface.

Basic/Detailed Setup Features Include:

1. Device Tag: The device tag identifies where the device will be

placed into service. A replacement device can be programmed to

have the same tag as the device it is replacing prior to installation.

2. Process Variable Units: Allows the user to select the units of mea-

sure (e.g., “wc, “Hg, psi, mbar, bar, kg/cm2, kPa, MPa).

3. Process Variable Limits: Allows the user to read the upper and

lower sensor limits and to read and adjust the upper and lower

range of the TX200H within the sensors limits and the allowable

turn-down range.

4. Device Description/Message: The user can program a text field that

reflects the function of the device.

5. Damping: The user can adjust the level of the damping applied to

the process variable. This feature is used to reduce the effect of

fluctuations in the readings. The value entered is the time constant

of the software filter, which adjusts the amount of damping.

Process Variables: can be read over the HART interface. Pressure is the

primary variable. Temperature is the secondary variable. NOTE: Reported

temperature is the ambient temperature at the back of the sensor and not

the process media temperature.

• Primary Variable: can be read in pressure units, percent of range or in mA.

• Secondary Variable: Available in °F

Diagnostic and Service: there are several TX200H diagnostic and service

features available over the HART interface.

1. Calibration: There are two ways to calibrate the TX200H.

a. If a calibrated pressure source is available, the user can apply a low

and high pressure and set the low and high range points.

b. If no pressure source is available, the user can manually enter values

for the upper range limit and the lower range limit.

2. D/A Trim: This feature allows the user to calibrate the D/A converter

that generates the 4-20mA signal. The output is first set to 4mA. The

user must measure and enter the loop current. The output is then set

to 20mA. The user again must measure and enter the loop current.

The output of the D/A is adjusted for offset and span.

3. Loop Test: The loop test feature forces the output current to a user

specified value. It can be set to 4mA, 20mA or to another value entered

by the user.

RECOMMENDED PRACTICES AND WARNINGS

United Electric Controls Company recommends careful consideration of the fol-

lowing factors when specifying and installing UE pressure and temperature units.

Before installing a unit, the Installation and Maintenance instructions provided

with unit must be read and understood.

• To avoid damaging unit, proof pressure and maximum temperature limits stated

in literature and on nameplates must never be exceeded, even by surges in the

system. Operation of the unit up to maximum pressure or temperature is accept-

able on a limited basis (e.g., start-up, testing) but continuous operation must be

restricted to the designated adjustable range. Excessive cycling at maximum

pressure or temperature limits could reduce sensor life.

• A back-up unit is necessary for applications where damage to a primary unit

could endanger life, limb or property. A high or low limit switch is necessary

for applications where a dangerous runaway condition could result.

• The adjustable range must be selected so that incorrect, inadvertent or mali-

cious setting at any range point cannot result in an unsafe system condition.

• Install unit where shock, vibration and ambient temperature fluctuations will

not damage unit or affect operation. When applicable, orient unit so that

moisture does not enter the enclosure via the electrical connection. When

appropriate, this entry point should be sealed to prevent moisture entry.

• Unit must not be altered or modified after shipment. Consult UE if modifica-

tion is necessary.

• Monitor operation to observe warning signs of possible damage to unit, such

as drift in set point or faulty display. Check unit immediately.

• Preventative maintenance and periodic testing is necessary for critical appli-

cations where damage could endanger property or personnel.

• Electrical ratings stated in literature and on nameplate must not be exceed-

ed. Overload on a switch can cause damage, even on the first cycle. Wire

unit according to local and national electrical codes, using wire size recom-

mended in installation sheet.

• Do not mount unit in ambient temp. exceeding published limits.
