Programmable Smart HART
Temperature Transmitter and Display
Introduction
This is the user’s manual for Moore Industries’
THZ2and 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 THZ2and TDZ2
The THZ2and TDZ2are 2-wire (loop-powered), user-
configurable, 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 THZ2and TDZ2allow 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 THZ2and TDZ2Device 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.
Model and Serial Numbers
Moore Industries uses the model and serial numbers
of our instruments to track information regarding each
unit that we sell and service. If a problem occurs with
your instrument, check for a tag affixed to the unit
listing these numbers. Supply the Customer Support
representative with this information when calling.

Configuring the THZ2and
TDZ2
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 THZ2or TDZ2with 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 THZ2or TDZ2can be connected to equipment
to simulate input and monitor output. You can then
change the transmitter’s operating parameters.

Device Specifications
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 THZ2or TDZ2must 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 THZ2or TDZ2to the PC
To set any of the options, you must first connect the
unit to the PC. The THZ2and TDZ2all 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 hook-
up diagrams, refer to Figures 7 or 8 (depending upon
your instrument’s housing).

Sensor Trimming– Sensor Trimming increases the
measurement accuracy of your instrument by match-
ing the reading of its actual input, to either a calibrated
source or the device to which it is connected. This veri-
fies 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 Tr i 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.
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 sen-
sor.
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 THZ2and 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 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.

Note:
Using the Scaling feature will disable the Custom
Curve capability. Since both are scaling features
used to manipulate the appearance of your process
variable, only one of these functions may be used at
a time.
Scaling– This allows you to customize your display
for your application. By example, if your process is
sending a -200°C to 850°C signal to the THZ2or TDZ2
and you wish to view the input as 0-100% then this
can be accomplished with the Scaling feature.
To scale your instrument, perform the following steps:
1. Check the Enabled box. The Sensor Range
boxes will display the range selected in the
Input Type section of the Input screen.
2. In the Scaled to text boxes, enter the values
you wish displayed when your input is at its
Zero Range and Full Range.
Once downloaded, your unit will display the scaled
values on its LCD and through HART communication.
Scaling PV Units of Measure– Use this to select
a preset HART EGU process variable display for
your scaled values. These HART EGU codes are
compatible with HART Revision 5, and earlier,
communications.
To customize your display and set your own EGU,
open the Display screen and use the Custom Label
feature.
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.

Custom Curve
Note:
Using the Custom Curve feature will disable the
Scaling capability. Since both are scaling features
used to manipulate the appearance of your process
variable, only one of these functions may be used at
a time.
Custom Curve–The Custom Curve feature allows you
to set up your own custom curve table. This allows
you to tell the transmitter what it should output when it
receives a certain input. This feature also allows you
the ability to write a table in Microsoft®Excel, save it
in a .csv format, and import it into the Configuration
Software. This makes it simple to save the custom
table for downloading to multiple units or for backup
purposes.
To create a custom curve:
1. Click the Enabled box.
2. Select the number of points for your curve
(128 points maximum) and enter it into the
No Of Points text box.
3. In the Custom Curve (Y) Range text boxes,
enter the values you wish displayed, and
represented as your 4-20mA span, when
your input is at its upper and lower ranges.
4. Type your individual values in the X data
and Ydata columns. Source variables
are inserted into the X Column, while the
corresponding data is inserted into the Y
Column.
5. After all of your data has been entered, you
must use the Custom Curve dropdown menu
to save your newly created custom table
(Save Custom Curve) and to download it to
your instrument (Download Custom Curve).
Custom Curve PV Units of Measure– Use this to
select a preset HART EGU process variable display for
your custom curve values. These HART EGU codes
are compatible with HART Revision 5, and earlier,
communications.
To customize your display and set your own EGU,
