The TMZ

The TMZ is a PC-Programmable, user-configurable,
signal converter. It has a digital output and retains the
high accuracy of an Analog to Digital converter without
the limitation of low resolution which is associated with
analog outputs. The multi-drop nature of the RS-485
port allows the connection of up to 32 units on a single
drop of cable that consists of two pairs of wires. The
TMZ has a READY LED to indicate the health of the
unit and an INPUT LED to indicate status.

Model and Serial Numbers

Moore Industries uses the model and serial numbers
of our instruments to track all information on each
unit that we sell and service. If a problem occurs
with your TMZ, check for a tag affixed to the unit
listing these numbers. Supply the Customer Support
representative with this information when calling.

Inputs

Refer to Table 4 for input ranges and accuracies of the
TMZ (TPRG).

Outputs

The TMZ has a standard RS-485 port that supports
the MODBUS RTU protocol.

Configuring the TMZ

One of the benefits of the TMZ is that there are no
internal or external controls to adjust or settings to
change. All operating parameters are set using a
PC and Moore Industries’ Intelligent PC Configuration
Software.

8 The Interface Solution Experts

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 disk.
The transmitter communicates with the PC through an
RS-232 connection to the PC’s serial port or through
the MODBUS output with a fixed baud rate at 19.2k.

TMZ

PC-Programmable MODBUS

Temperature Transmitter

Installing the Configuration
Software

Refer to Table 6 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
“TMZ 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 TMZ can be connected to equipment to
simulate input and monitor output. You can then
change the transmitter’s operating parameters.

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 the benefit of input from a sensor or TMZ.

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

The TMZ must be connected to the PC in order to:
perform sensor trimming; assign a tag, descriptor or
message; receive (via download) a configuration file;
and save the configuration file from the transmitter’s
memory.

The latest version of our Configuration Software for
your TMZ unit is also available for download on our
website www.miinet.com.

Running Average Filter– This function is for
filtering the input signal. The TMZ provides this filter
with a user-selected range between 1 and 16. Factory
default is 4.

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.

Input Filter– This setting is used to configure the
input filter. This filter is designed to reduce the effects
of mains-induced noise. The input filter frequency
value should be set to the frequency of the local AC
supply-either 50Hz or 60Hz.

Note:

Once you have configured all parameters, download

to the unit by selecting “Download” in the Transfer

dropdown menu located in the Status Bar. You may

also download by clicking the button in the

Tool Bar.

Input Range– Allows you to set your “Upper
Range Value” (URV) and “Lower Range Value” (LRV)
depending upon the input configuration and range
chosen in the Input Type section.

Note:

The upper and lower range values will, by default, be

set to the maximum range determined by input type
with the exception of thermocouple and RTD inputs,

which have fixed range values user cannot change.

Temperature Measurements– Select the unit in
which you wish your Input Range displayed. Choose
from Deg C, Deg F, Kelvin or Deg R.

Broken Wire– Allows the TMZ to continuously
test the integrity of your sensor wiring by sending
out random microamp pulses during operation. If a
problem is detected, a message is displayed in the
Device Status box.

You may also use the Quick Set feature to configure
your Input parameters and download the settings.

Trimming

Figure 7. Trimming Tab

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 from the sensor
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” and “Trim” values.

2. Enter the values that need to be trimmed into the
“Set Value” field and click “Set”.

3. Apply the targeted signal to the input, wait until it
settles and click “Trim” 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 Status Bar. You may

also download by clicking the button in the

Tool Bar.

Scaling & Custom Curve

Figure 8. Scaling & Custom Curve Tab

Scaling– Scaling allows you to take your PV
(Process Variable) reading and manipulate it to a more
customized display range (Scaled PV). PV is the unit
read after selecting your input type. For example,
choosing a mV input would then produce a PV
displayed in mV.

Should you require a Scaled PV, follow the instructions
below.

1. In the “PV” parameter, enter the actual range of
your input type. Place the minimum value in the “LRV”
text box and the maximum value in the “URV” box.

2. In the “Scaled PV” parameter, enter the scale, or
range you require. In the “LRV” text box, enter the
value that you wish displayed when your reading is at
its minimum. In the “URV” text box, place the value to
be displayed when the process variable has reached
maximum.

Custom Curve– The Custom Curve feature
allows you to setup 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 (32
points maximum).

3. Type your individual values in the X and Y columns.
Source variables are inserted into the X column while
the corresponding data is inserted into the Y column.

4. After all of your data has been entered, you must
use the Custom Curve dropdown menu to save your
newly created custom (“Save Custom Curve”) and to
download it to your TMZ (“Download Custom Curve”).

Note:

Once you have configured all parameters, download

to the unit by selecting “Download” in the Transfer

dropdown menu located in the Status Bar. You may

also download by clicking the button in the Tool

Bar. However, this does not download your custom

table. To do so, you must use the Custom Curve

dropdown menu.

TMZ

PC-Programmable MODBUS
Temperature Transmitter

Installation

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

Mounting the TMZ

The TMZ can be mounted on standard DIN mounting
rails.

Making the Electrical Connections

Please refer to Figure 4 for electrical connections.

CE Conformity

Installation of any Moore Industries’ products that
carry the CE marking must adhere to the guidelines in
the Recommended Ground Wiring Practices section in
order to meet the EN 61326 requirements set forth in
the applicable EMC directive.

Operation

Once programmed, calibrated, installed, and supplied
with the correct power, the TMZ transmitter begins to
operate immediately. Depending upon environmental
conditions, it can be expected to operate unattended
for extended periods of time.

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.

Maintenance

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

RETURN PROCEDURES

To return equipment to Moore Industries for repair, follow these four steps:

1. Call Moore Industries and request a Returned Material Authorization (RMA) number.

Warranty Repair –
If you are unsure if your unit is still under warranty, we can use the unit’s serial number
to verify the warranty status for you over the phone. Be sure to include the RMA
number on all documentation.

Non-Warranty Repair –
If your unit is out of warranty, be prepared to give us a Purchase Order number when
you call. In most cases, we will be able to quote you the repair costs at that time.
The repair price you are quoted will be a “Not To Exceed” price, which means that the
actual repair costs may be less than the quote. Be sure to include the RMA number on
all documentation.

2. Provide us with the following documentation:
a) A note listing the symptoms that indicate the unit needs repair
b) Complete shipping information for return of the equipment after repair
c) The name and phone number of the person to contact if questions arise at the factory

3. Use sufficient packing material and carefully pack the equipment in a sturdy shipping con­tainer.

4. Ship the equipment to the Moore Industries location nearest you.

The returned equipment will be inspected and tested at the factory. A Moore Industries rep­resentative will contact the person designated on your documentation if more information is
needed. The repaired equipment, or its replacement, will be returned to you in accordance
with the shipping instructions furnished in your documentation.
