Introduction

This is the user’s manual for Moore Industries’ THZ2 and TDZ2 (TPRG: RTD, T/C, Ohms, mV and Potentiometer inputs) Programmable Smart HART Temperature Transmitter and Display. It contains all of the information needed to conﬁgure, install, operate and maintain the instruments.

About this Manual

Pay particular attention wherever you see a “Note”, “Caution” or “WARNING ”.

Note– Information that is helpful for a procedure, condition or operation of the unit.

Caution– Hazardous procedure or condition that could damage or destroy the unit.

WARNING– Hazardous procedure or condition that could injure the operator.

The THZ2 and TDZ

The THZ2 and TDZ2 are 2-wire (loop-powered), userconﬁgurable, HART®-based temperature transmitters. Their size, accuracy and compatibility make them the ideal solution when measurements must be made in remote or otherwise difﬁcult-to-access locations.

The THZ2 and TDZ2 allow for conﬁguration through two methods. You may use your PC’s RS-232 serial port or USB port and Moore Industries’ PC Conﬁguration Software (once installed onto your PC). All conﬁguration parameters are available through the PC Conﬁguration Software.

The second method is to connect a HART Communicator and HART modem into your process loop. You must ensure that your communicator is conﬁgured with the THZ2 and TDZ2 Device Description (DD). You may then conﬁgure most parameters through the Communicator. Custom Curve variables cannot be entered using the Communicator. They must be conﬁgured using the PC Conﬁguration Software.

Conﬁguring the THZ2 and TDZ

One of the beneﬁts of these transmitters is that there are no internal or external controls to adjust or settings to change. All operating parameters are set using either a HART Communicator or a PC and Moore Industries’ Intelligent PC Conﬁguration software.

The software settings are downloaded to the transmitter in the form of a Conﬁguration File and stored in the instrument’s memory. You can save a backup copy of the ﬁle on your PC hard drive or external media. The transmitter communicates with the PC through an RS-232 port or USB port. A HART modem connection to the PC’s serial port may also be used.

You can conﬁgure the THZ2 or TDZ2 with either a standard HART Communicator or our PC software. Figures 7 and 8 (depending upon your instrument’s housing) and Table 5 provide the information you need to conﬁgure your unit.

Using a PC If you are going to use a PC to conﬁgure your unit, ﬁrst install the software as described on the next page, then setup the hardware as shown in Figures 7 or 8 (depending upon your instrument’s housing).

Installing the Conﬁguration Software

Refer to Table 5 for the equipment needed.

1. Insert the Moore Industries Interface Solution PC Conﬁguration Software CD into the CD drive of the PC. Access the CD and open the THZ2_TDZ2 PC Conﬁguration Software folder.

2. Double-click the installation program located in the folder. Follow the prompts to correctly install the program.

Once the Conﬁguration Program is installed on the PC, the THZ2 or TDZ2 can be connected to equipment to simulate input and monitor output. You can then change the transmitter’s operating parameters.

Programmable Smart HART Temperature Transmitter and Display

No Transmitter Needed

It is not necessary to connect the transmitter to a PC to create conﬁguration ﬁles using the software. The Conﬁguration Program can be run without connecting a transmitter, and most parameters can be set without beneﬁt of input from a sensor or transmitter.

This makes it easy to create a set of operating parameters, save them to external media, and download them to one or more transmitters at a later time.

The THZ2 or TDZ2 must be connected to the PC in order to: trim input, trim output, assign a tag, perform a loop test, receive (via download) a conﬁguration ﬁle and save the conﬁguration ﬁle from the transmitter’s memory.

Connecting the THZ2 or TDZ2 to the PC

To set any of the options, you must ﬁrst connect the unit to the PC. The THZ2 and TDZ2 all have the same terminal designations regardless of housing style, and all can be setup using the connections shown in Figures 7 and 8 (depending upon your instrument’s housing).

Establish a simple current loop for the transmitter by connecting a 24 Volt power supply, a 250 ohm resistor and the transmitter in series. See Table 5 for information on the necessary equipment.

Connect your instrument to the PC via the RS-232 serial port using Moore Industries Interface cable or USB cables listed in Table 5.

A HART modem may also be used to connect your unit to the PC. Connect the RS-232 end of the modem to the PC’s COM port, then connect the HART output end of the modem (two hook-up wires) across the transmitter or the load resistor. For hookup diagrams, refer to Figures 7 or 8 (depending upon your instrument’s housing).

Broken Wire Detection– During operation, the THZ2 and TDZ2 send random microamp pulses through input wiring to check for broken wiring or a burned out sensor.

To utilize Broken Wire Detection, check the Enabled box. If a failure is detected, a message will appear in the THZ2/TDZ2 Status box.

Running Average Filter Settings– This function is for ﬁltering the input signal. The THZ2 and TDZ2 provide this ﬁlter with a user-selected range between 1 and 16. Factory default is 1.

Note:

A higher Running Average Filter setting provides

smoother output transitions; however, reduces

response time. Conversely, a lower setting provides

a faster response time, but may seem more unstable.

PV Damping–PV Damping allows you to introduce a delay into the response of your unit in order to stop short-lived spikes from initiating faults and generating fault messages.

The conﬁgured damping period will determine the time response that the analog output will take to achieve a 66% change in output in response to a stepped input.

To enable PV Damping, select the Enabled button. Use the arrows to select a value between 1sec and 30sec.

Sensor Trimming– Sensor Trimming increases the measurement accuracy of your instrument by matching the reading of its actual input, to either a calibrated source or the device to which it is connected. This veriﬁes that the input to the transmitter is being interpreted correctly.

You may trim any point between 0% and 100% along the scale. Note that one-point trimming applies an offset to the sensor reading, while two-point trimming applies both an offset and a gain.

Follow the steps below in order to perform sensor trimming.

1. Select either 1 Point (one-point trimming) or 2 Points (two-point trimming) by clicking the appropriate button. Each pair consists of Set Value and Tr i m ﬁelds.

2. Enter the values that require trimming into the Set Value ﬁeld and click Set.

3. Apply the targeted signal to the input, wait until it settles, and click Tri m to capture the measured value. If you chose 2 Points, repeat the step above for the second point.

Note:

Once you have conﬁgured all parameters, download

to the unit by selecting Download in the Transfer

dropdown menu located in the Menu Bar. Or, click

the button in the Tool Bar.

Sensor Range– Allows you to set your upper and lower range values within the range chosen in the Input Type section.

The desired Upper and Lower Range settings can be entered via your PC keyboard or captured. To capture an input, follow the steps below.

1. Apply the desired Upper Range input and press the corresponding Capture button.

2. Next, apply the desired Lower Range input and press the corresponding Capture button.

Using the HART Communicator

The THZ2 and TDZ2 can be programmed using a HART Communicator. If your communicator is equipped with the Device Description (DD) for your transmitter, The HART Communicator Menu with a Device Description section gives an overview of the menus and instructions for programming.

If your communicator is not equipped with the required Device Description, go to The HART Communicator Menu without a Device Description section of this manual. Even if your communicator is not up to date, most of the important programming features can be accessed without the THZ2 and TDZ2 DD by using the Generic HART DD available on HART Communicators.

If you are using a Fisher-Rosemount Model 375 HART Communicator, or other host, you may download the latest Moore Industries DD at www.hartcomm.org. The THZ2 and TDZ2 DDs are available on the HART Foundation’s Device Driver Library Release December 2005 and later.

For installation of the latest device description through the HART Foundation, send the Communicator to the the following address:

Include Moore Industries’ conﬁguration sheet indicating the Device Descriptions that you require. We will load the Device Descriptions of your choice for a nominal charge.

Programming When a Device Description is Available

Note:

All parameters, except the Custom Curve feature,

can be conﬁgured using the HART Communicator.

The Custom Curve table can only be conﬁgured

using the PC Conﬁguration Software Program.

With the transmitter connected as illustrated in Figures 7 or 8 (depending upon your instrument’s housing) apply power and turn on the communicator. After a brief self-test, the communicator will show the main menu and identify the unit as a THZ2 or TDZ2.

This section contains the instructions for programming the transmitter using a HART Communicator that has been programmed with a HART Device Description. If your communicator does not have the appropriate Device Description, skip to The HART Communicator Menu without a Device Description section of this manual. Figure 15 shows an overview of the programming menus for the conﬁguration process.

6 Dev id– This is a read-only value that uniquely identiﬁes the ﬁeld device when combined with the manufacturer identiﬁcation and device type.

Note:

If the polling address is set to 0, the transmitter is

automatically set to analog mode. Multiple units on

the same bus must have different addresses.

2 Burst mode– This function allows you to achieve a

higher data rate. When enabled (On), your instrument repeatedly transmits a data message as if it were being commanded to do so. The Master device receives the data more frequently than if it were only polling the transmitter, achieving a higher data trasnfer rate.

7 Hardware rev– This value corresponds to the revision of the electronics hardware of the ﬁeld device.

F. Conﬁgure Display

This menu only applies to the TDZ2 as it is used to conﬁgure the manner in which the display is viewed.

1 Mode– Select whether your variable is displayed as a PV, current value or a percent.

2 Decimal Places– Choose the resolution of your value. Select one, two or three decimal places. You may also choose Auto to allow the instrument to automatically select the decimal placement.

3 Custom Label– Enable or disable custom label for use on the display.

4 Label Displayed– Select your custom label. Enter all capitalized characters or an accepted numeric value.

5. Diagnostic & Service Menu– Allows you to perform diagnostic functions (device test and loop tests) and sensor trimming.

1 Test device– Directs you to a Status sub-menu. When accessed, it causes the THZ2 or TDZ2 to perform a self test of its electronics. Any errors that occur are reported on the communicator.

2 Sensor Trimming– This menu allows you to view previously conﬁgured Sensor Trim Mode settings.

3 Loop Test– A loop test may be performed in order to check output performance and accuracy and to trim other instruments in the loop. Your output will be a current value, in mA, equal to the value you input. You can check the other current devices on the loop and calibrate them to this signal.

TDZ

From the menu, select whether to perform the test at 4mA (low end value), 20mA (upper end value) or at another speciﬁed value. Once you have competed your test, select End.

It will also allow you to introduce Device Variable Trim (Step 4) which allows for calibration measurement of a device variable to be adjusted linearly. You may also enable Device Variable Trim Reset (Step 5) which al- lows for the device variable to be reset to the factory trim default settings.

6. Review Menu–This is a read-only menu that provides information on both Device Parameters and De- vice Information. Refer to the Review menu portion of Figure 15 for a description of the parameters included in this menu.

The HART Communicator Menu Without a Device Description

This section contains the instructions for programming a THZ2 and TDZ2 using a HART communicator without a Device Description. If your communicator has a Device Description, please see The HART Com- municator Menu with a Device Description section of this manual.

1. Online Generic– The initial screen, the Online Ge- neric menu, displays the process value, analog output

and the programmed upper and lower parameters of the process value. The generic HART Communicator overview menu (Figure 16) shows the screen. Use the Device Setup menu for conﬁguring your THZ2 and TDZ2.

2. Basic Setup– The Basic Setup menu allows you to enter a name for an individual transmitter, the units of measurement, the upper and lower range and sensor values, and a damping time between 0sec and 30sec.

3. Analog Output– The Analog Output menu displays the analog output, changes the loop current to a ﬁxed value so that it can be checked against the value being received and displayed by your receiving device, and enters and trims the sensor.

4. HART Output– From the HART Output menu, you can enter the polling address and display the number of preamble characters sent by the master to the slave to ensure synchronization.

If the polling address is set to 0, the THZ2 and TDZ2 is automatically set to analog mode. Multiple units on the same bus must have different addresses.

Installation

Installation consists of physically mounting the unit and completing the electrical connections.

Mounting the THZ2 or TDZ

The THZ2 HPP ﬁts inside a 30-35mm connection head (such as the LH1) using captive mounting screws. The THZ DIN2 can be mounted on standard DIN mounting rails. The TDZ2 HP can be mounted with rails, ﬂanges, or in one of our larger housings, such as the D-BOX or BH.

Making the Electrical Connections

The connections for the various inputs are shown in Figures 7 and 8. The ﬁgure shows a single transmitter. If you are using multiple units, connect them using the connections shown in Figure 17.

In multi-drop networks, the unit’s receiving device is normally a HART-communicating control system acting as the HART Primary Master. The control system uses each transmitter’s individual address to access real-time process data, sensor diagnostics and THZ2 or TDZ2 diagnostic data. The address is also used to locate the appropriate unit, to initiate conﬁguration and to calibrate. A HART communicator, acting as the HART Secondary Master, can be used to simultaneously access information from, or transmit conﬁguration information to the transmitter from anywhere along the HART digital link.

Make sure that the total loop resistance is at least 250 ohms so that the 4-20mA signal containing the HART protocol is not shorted. If loop resistance is less than 250 ohms, add a resistor.

Recommended Ground Wiring Practices

Moore Industries recommends the following ground wiring practices:

• AnyMooreIndustriesproductinametalcaseor

housing should be grounded.

• Theprotectiveearthconductormustbeconnected

to a system safety earth ground before making other connections.

• Allinputsignalsto,andoutputsignalsfrom,

Moore Industries’ products should be wired using a shielded, twisted pair wiring technique. Shields should be connected to an earth or safety ground.

• Forthebestshielding,theshieldshouldberun

all the way from the signal source to the receiving device. (see Note below)

• Themaximumlengthofunshieldedinputand

output signal wiring should be 2 inches.

Note:

Some of Moore Industries’ instruments can be

classiﬁed as receivers (IPT 2, IPX 2, etc.) and some

can be classiﬁed as transmitters (TRX, TRY, etc.)

while some are both a receiver and a transmitter

(SPA 2, HIM, etc). Hence, your shield ground

connections should be appropriate for the type

of signal line being shielded. The shield should

be grounded at the receiver and not at the signal

source.

Switches and Circuit Breakers

A switch or circuit breaker must be wired in series with the AC power conductors. The switch or circuit breaker used must be located within three meters of the unit.

WARNING:

Terminals on this unit may be connected to

hazardous voltages. Before making ANY

connections to this unit, ALL hazardous voltages

must be de-energized.

32 The Interface Solution Experts

The circuit breaker or switch will only remove power to the unit, hazardous voltages may still be connected to other terminals on the unit.

Installation Category

All of Moore Industries’ terminals are rated CAT II, except those with the -RF option. These terminals are rated CAT I.

Equipment Ratings

The THZ2 and TDZ2 do not generate hazardous voltages, rather, they accommodate a temperature input, and generate a low voltage current output. Products connected to the THZ2 or TDZ2 should be designed to receive these inputs.

Supply Wiring

All power connections should be made with the proper wire.

The end of each conductor should be stripped no more than 8mm (0.31 in). The end of the stripped wire should be tinned with solder, or inserted into a ferrule and crimped before being placed into a terminal block.

Conductors connected to screw-type connections should have a ring-lug or spade-lug crimped onto the wire end.

THZ

Operation

Once programmed, calibrated, installed and supplied with the correct power, THZ2 and TDZ2 transmitters begin to operate immediately. Depending upon environmental conditions, they can be expected to operate unattended for extended periods of time.

HART Protocol

This section of the manual gives an overview of the HART format used by THZ2 and TDZ2 modules during operation. Use the information in this section to process the data provided by the module(s) during operation. For more information on the HART protocol, contact the HART Foundation at:

HART Communication Foundation 9390 Research Blvd., Suite I-350 Austin, TX 78759-6540 USA Phone: (512) 794-0369 Fax: (512) 794-3904 www.hartcomm.org

Device Types

To implement two-way communication between the THZ2 and the device being used to conﬁgure it or receive its information, the THZ2 and TDZ2 operate in a HART Master/Slave structure. The THZ2 or TDZ2 is the Slave (or slaves in a multidrop network).

There can be two Masters per system: a Primary Master and a Secondary Master. Masters are typically either a HART Hand-Held Communicator or a HARTbased control system.

Communication Speed and Format

The speed of the HART transmission is 1200 bps. The time delay between a master initiating a request for data from a slave and the slave receiving and acknowledging the request depends upon which command is issued. Generally, a master can poll a slave 2-3 times per second.

The byte structure of the HART signal is:

1 Start Bit, 8 Data Bits, 1 Odd Parity Bit, 1 Stop Bit.

Maintenance

Moore Industries suggests a quick check for terminal tightness and general unit condition every 6-8 months. Always adhere to any site requirements for programmed maintenance.

Customer Support

If service assistance is ever required for an device in your application, refer to the back cover of this manual for the telephone numbers to Moore Industries’ customer service department.

If possible, make a note of the model number of the unit before calling. For fastest assistance, have the following information available: serial number, the job number and purchase order number under which it was shipped

In many applications, the Primary Master is a HART Hand-Held Communicator. The communicator is used solely as a conﬁguration tool to set up the transmitter, periodically view its real-time process measurement, or view its operating and diagnostic information from a loop termination point.

Digital Signal

One of the advantages of the HART protocol is that the digital information is conveyed by the same wires used to output the 4-20mA signal. After being polled by the master, the THZ2 or TDZ2 responds to the inquiry by modulating the 4-20mA current 0.5mA above or below the output signal. 1200 Hz represents 1 and 2200 Hz represents 0.
