Quick-Start

Most users familiar with a PC and Windows will not ha v e a need for the inf ormation in this manual. Moore Industries suggests that if you do need to refer to the information here, rely heavily on the Table of Contents that follow this Quick-Start Guide.

The majority of conﬁguration work with these transmitters can be carried out from the Main Conﬁguration Screen of the PC Conﬁguration Program (see Figure 3, page 8). The menus and screen prompts are in “plain english”, and the help system should guide most users through most of the conﬁguration procedures without any problems.

In general, the use of the TRY or TRX transmitter follows this path:

1. Installing the Conﬁguration Software (page 10)

2. Connecting the TRY/TRX to the PC (page 10)

3. Input Connection Hookups (page 11)

4. Scale the Input (page 15)

5. Scale the Output (page 16)

6. Trim the Input (page 17)

7. Trim the Output (page 17)

8. Download the Conﬁguration File (press PROG button)

9. Save the Conﬁguration File to disk for future reference or use with another unit (page 22)

10. Install the unit (page 23)

Introduction

The TRY and TRX are 2-wire (loop-powered) temperature transmitters. They are conﬁgured using a personal computer (PC) and the software program provided by Moore Industries.

About this Manual

Wherever you see a “Note”, “Caution”, or “WARNING ” pay particular attention.

• A“Note” provides information to help you avoid mi- nor inconveniences during calibration, installation, or operation of the TRY and TRX.

• A“Caution” provides information on steps to take in avoiding procedures and practices that could risk damage to the TRY and TRX or other equipment.

• A“WARNING ” provides information on steps to take in avoiding procedures and practices that

could pose safety risks to personnel.

Figure 1. Use the PC-Programmable TRY or TRX as an interface between temperature sensors and control systems such as a DCS, PLC or PC-based control system.

The TRY & TRX

Both the TRY and the TRX transmit input from a thermocouple, or an RTD, a direct resistance or millivolt source, or a potentiometer as a linearized, scaled and offset 4-20 milliamps (mA). Their output signal is proportional (or, by user designation inversely proportional) to the input. Refer to Figure 1.

The TRY provides 1500Vrms isolation between input and output (500Vrms isolation for the DIN-style version). The TRX is a non-isolating transmitter.

Model and Serial Numbers Moore Industries uses a system of model and serial numbers to keep track of all of the information on every unit it sells and services. If a problem occurs with a TRY or TRX, check for a tag afﬁxed to the unit listing these numbers. Supply the Customer Support representative with this information when calling.

If additional units are needed, use the information printed in bold text in the table above to “build” a model number for the type of transmitter required.

Each TRY or TRX order comes with one copy of our Conﬁguration Software (Windows 2000, XP, Vista, and 7 compatible).

To order additional or replacement cables, specify Moore Industries’ part number 803-040-26, or 803-039-26 for the special cable equipped with its own, self-powered input-to-output isolation circuit for operation in areas of high ground potentials.

TRY & TRX

Conﬁguring a TRY/TRX

One of the beneﬁts of the TRY and TRX transmitters is their easy-to-use PC Conﬁguration Program; there are no internal or external controls to adjust or jumpers to change. All operating parameters are set using the PC program included with each shipment. These settings are downloaded in the form of a Conﬁguration File into nonvolatile unit memory (EEPROM) over a connection between the PC’s serial (COM) port and a COM port on the transmitter.

This section of the manual contains instructions for conﬁguring the TRY or TRX:

• SettingOutputDamping,UsingtheLoopTest

(page 15)

What is First

First, it is necessary to install the Conﬁguration Program on a PC. Once the program is loaded and running, nearly all of the operating parameters for the connected transmitter are shown on a single screen (see Figure 3). This makes it easy to determine which aspects of transmitter operation need to be changed to suit the application requirements.

What is Next

Once the Conﬁguration Program is installed on the PC, the TRY or TRX can be connected to equipment to simulate input and monitor output, and with the PC program, the user can view and/or change its operating parameters.

No T ransmitter Needed

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

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.

Note, however, that not all parameters can be set without a transmitter. In some cases, a source of input is also required.

The transmitter must be connected to the PC in order to:

Page 10

TRY & TRX

Installing the Conﬁguration Software

Refer to Table below 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 “SDY SIY TDY TRX TRY 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 SIY can be connected to equipment to simulate input and monitor output. This makes it easy to create a set of operating parameters, save them to disk, and download them to one or more instruments at a later time.

Gathering the Equipment Needed

It is possible to create a Conﬁguration File for a transmitter without ever connecting the transmitter to a PC. Most TRY or TRX operating parameters can be set up, saved in a Conﬁguration File, and stored on disk entirely within the Conﬁguration Program— without ever communicating with a transmitter.

It is not possible to trim the transmitter input or output without a transmitter, a source of input, and a meter (for output trimming). Likewise, it is not possible to use the Loop Test function of the transmitter unless everything is setup as shown in Figure 2, and it is not possible to store a tag name in the memory of a transmitter without connecting that transmitter to the Conﬁguration Program.

Table 2 lists the things needed to setup the TRY or TRX as shown in Figure 2.

Note:

Be sure to use calibrated test equipment when

performing any trimming operations on the TRY or

TRX. Moore Industries uses equipment rated 5:1

over the rated accuracy of the unit under test.

We recommend the use of equipment

rated at least 3:1.

Connecting the TRY or TRX to the PC

Connect the RS-232 end of the cable to the PC’s COM port.

See Table below for information on the necessary equipment.

TRY & TRX

Keeping What You’ve Got Safe— Using “Get Setup”

Every TRY or TRX is shipped from the factory with a Conﬁguration File already installed in its memory. This ﬁle is comprised of either the factory default set of operating parameters, or of the set of parameters speciﬁed by the customer at the time of order.

CAUTION:

Any time a connected TRY or TRX is “programmed”

by downloading a Conﬁguration File into memory,

ALL of the conﬁguration parameters

resident in the transmitter memory

at the time of the download are OVERWRITTEN

with whatever parameters are showing

on the Conﬁguration Program Screen. All previous

parameters are then unrecoverable.

This includes things like, input type, tag name,

calibration date, input and/or output trim values, etc.

IMPORTANT:

To safeguard against the accidental loss of a

Conﬁguration File, always use the “Get Setup” button

and the File Management facilities under the “File”

button, located at the bottom-center of the

Main Conﬁguration Screen.

2. Click on the “Get Setup” button at the bottomcenter of the Conﬁguration Program Main Screen (see Figure 3).

The screen will ﬂicker once, and the settings

shown on the left area of the screen will match those showing on the right.

3. Click on the “File” button. This brings up an Explorer-like set of windows on the left area of the screen.

4. Enter a name for the current Conﬁguration File (the one already in the transmitter’s memory), and click on the “Save” button.

Note:

File names must follow the DOS convention; Eight-

character maximum and no sufﬁx.

TRY & TRX

CAUTION:

Any time a connected TRY or TRX is “programmed”

by downloading a Conﬁguration File into memory,

ALL of the conﬁguration parameters resident in the

transmitter memory at the time of the download are

OVERWRITTEN.

This includes things like, tag name, calibration date,

trim values, etc.

Trimming the Input

Use this feature to enhance the accuracy of the transmitter by precisely matching its actual reading of the input to its scaling of the either one or two input points. Trim the input by following the directions below:

Note:

The “Input Trim” procedure may require several

hours for completion. Please determine whether

or not your process requires this function before

proceeding.

7. Attach the sensor that you wish to trim to the

transmitter and place the sensor in a calibration bath. Adjust the bath until its temperature settles. Click “Trim Upper” and wait for it to capture the value (about 10 seconds).

Caution:

If planning on beginning a new task, ensure that you

have saved your lower trim value of your Input Trim

before proceeding to Steps 8 and 9.

8. Click on the button labeled “QuitTrim”, then the

“Stop” button, and ﬁnally the “Prog” button to send the trim values to the transmitter.

9. Click on the “Start” button to re-enable the

Conﬁguration Program’s monitoring of the connected transmitter.

Figure 9. Trim Capture Box

1. Connect the transmitter to your PC using the setup shown in Figure 2. Press the “Get Setup” button to display the transmitter’s current conﬁguration.

2. Click “Start”, then “InpTrim”.

3. Click the radio button labeled “Input Trim On”.

4. Select whether you will trim two points (upper and lower) or just one point by clicking on the appropriate radio button in the “Trim Pnts” section.

5. In the “Trim Lower” and “Trim Upper” boxes, type in the sensor’s value that you are trimming.

6. Attach the sensor that you wish to trim to the transmitter and place the sensor in a calibration bath. Adjust the bath until its temperature settles. Click “Trim Lower” and wait for it to capture the value (about 10 seconds).

Trimming the Output

Trimming is the function that allows precise control over the transmitter’s output. Note that to activate this function, a unit must be connected as shown in Figure

2. To trim TRY or TRX output:

1. Set all unit parameters on the TRY or TRX Conﬁguration Screen as required for your intended application.

When the Conﬁguration File shown on the screen

has been modiﬁed for your application, click “Stop” to stop measurement.

2. Click “OutTrim”. Monitor the output with a calibrated current meter or with a voltmeter measuring the drop across a precision 250 Ohm resistor (see Figure 2).

3. While monitoring your meter, select and move the “Zero Scale Output” or the “Full Scale Output” slide bar to adjust the TRY or TRX output .

4. When both zero and full scale have been adjusted to satisfaction, press “QuitTrim”, then “Prog” to program the transmitter with the new trim values.

The “TRY or TRX Status” area of the Conﬁguration

Screen will reﬂect the new output settings.

Setting Miscellaneous Functions— Engineering Unit Readout, Input Filtering, Upscale or Downscale Drive, and Broken Wire Detection

There are several “radio buttons” on the PC Conﬁguration Program Main Screen that control ancillary transmitter functions. It is not necessary to have a transmitter hooked up to the PC in order to set these parameters and save them in a Conﬁguration File.

Setting Engineering Unit Readout

When a temperature sensor is designated as the input to the transmitter, the radio buttons for “Degree” are enabled.

Use this setting to have the Conﬁguration Program display the Centigrade or Fahrenheit temperature for readout in the “Status” area of the screen whenever the PC is being used to monitor the input from the connected sensor.

Setting Input Filtering

Use this radio button setting to ﬁlter out noise on the power to the transmitter.

Note:

There is a difference between the available

Full Scale output setting and the Upscale Drive,

and between the available zero scale output setting

and the Downscale Drive:

The TRY or TRX will only output 24mA or 3.3mA

(as conﬁgured) in the event of a sensor or sensor

wiring failure (upscale/downscale drive).If sensor

input drops below the rated range, output drops to a

minimum of 3.8mA. If sensor input rises above the

rated range, output rises to 21.4mA.

This allows the user to distinguish between an input

failure and an input over or under-range condition.

Disabling Broken Wire Detection

One of the premier features of many of Moore Industries’ temperature transmitters is our Total

Sensor Diagnostics® system. During operation, the TRY or TRX sends random micro-amp pulses through input wiring to check for broken wiring or a burned out sensor.

Working with a Millivolt Input

When the transmitter is connected to a PC, the “TRY/TRX Status” section of the Main Conﬁguration screen displays the message “Broken Wire” whenever problems are detected on the input, and the transmitter itself drives its output upscale or downscale.

This can cause problems for some types of millivolt input sources. To temporarily disable this feature when the TRY or TRX is working in a millivolt input conﬁguration, select the “Broken Wire Off” radio button.

Working with a Thermocouple or RTD Input Total Sensor Diagnostics can also cause problems with some types of temperature calibrators.

Choosing Between Upscale and Downscale Drive

The TRY and TRX transmitters can be conﬁgured to provide a special warning, using its output, of a breakdown in its connected sensor or sensor wiring. Use this radio button setting to conﬁgure the transmitter to drive its output either up to 24mA or down to 3.3mA when a sensor or sensor wiring failure is detected.

18 Demand MOORE Reliability

When working with thermocouple or RTD inputs, set the “Calibration” radio button in the lowerleft area of the Conﬁguration Screen to “Calibration Mode”. This temporarily disables Total Sensor Diagnostics.

Page 19

TRY & TRX

Setting Output Damping

The Output Damping function allows the user to introduce a delay into the response of the transmitter in order to minimize the effect of step output changes. The higher the damping value (set in seconds), the longer the TRY or TRX will take to respond to trends on the input.

Note:

It is not necessary to connect an input device to the

PC in order to select and conﬁgure the Damping

Value.

To set the damping value, either adjust the position of the slider bar in the lower-right area of the Conﬁguration Program Main Screen, or enter a value directly into the space provided.

The default damping value is 0 seconds in which damping is off. The maximum allowable damping value is 5.056 seconds.

Using the Loop Test

The Loop Test feature allows the user to employ the transmitter’s output to “trim” other instruments in the loop.

To use the Loop Test feature, the connected TRY or TRX must stop measuring input.

1. Click on the “Stop” button.

2. Click on the “Loop Test” button. This enables a slide bar in the lower-right area

of the Conﬁguration Screen.

3. Use the slide bar to adjust the output of the connected TRY or TRX to a percentage of the conﬁgured scale. Monitor the effect of this on other instruments in the loop, and adjust accordingly.

4. Click on “Quit Loop” to stop using the Loop Test feature.

Creating a Custom Linearization T able

The TRY or TRX support user-deﬁned linearization of mV inputs. Up to 85 input/output points can be deﬁned, and the user can also specify the format and engineering units of the output (viewable with the Conﬁguration Program). A Custom Linearization Curve is used for mV inputs only.

This section explains how to create a Custom Linearization Table for downloading into TRY or TRX memory.

The instructions assume that the Conﬁguration Program has been loaded successfully. Moore Industries also suggests saving the initial settings resident in the transmitter before making any changes.

To create a Custom Linearization Table:

1. Attach the equipment listed in Table 1 as shown in Figure 2 and start the PC Conﬁguration Program.

Figure 12. Creating a Custom Linearization Table.

Note:

Connect the unit to a PC in order to create a Custom

Linearization Table. You may work On or Off-Line.

2. Use the pull-down menu to set “Linearization ON”. Then click the “CustTabl” button in the lower-left area of the Main Conﬁguration Screen.

Figure 11. Linearization Must be set to ON to Create a Custom Table.

3. Click on the “CustTabl” (Customize Linearization Table) button. This causes the Conﬁguration Program to change its upper-right corner area to accommodate the table.

4. Use the table ﬁelds to set values for input and output from the transmitter’s intended application.

Use the Up, Down, Left, and Right arrow keys on the PC keyboard to move the cursor among the cells in the table.

5. Use the “Restore” button to reset the table to the table stored in the TRY OR TRX’s memory.

CAUTION:

Restoring the conﬁguration ﬁle erases any values in

the table, overwriting them with whatever is stored in

the most recent ﬁle.

6. Use the “EGU” ﬁeld to set the Engineering units of the readout from the transmitter when connected to the Conﬁguration Program.

7. Set the “Output Format” ﬁeld to the desired resolution using the pull-down menu.

8. Enter the number of points to use to constitute the Linearization Table in the “Points” ﬁeld.

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.

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

, 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.

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.

Operating the TRY/TRX

Once conﬁgured, installed, and supplied with the correct power, the TRY or TRX transmitter begins to operate immediately. Depending upon environmental conditions, it can be expected to continue to operate unattended indeﬁnitely.

Figure 17. The Dimensions of the explosion-proof housing for the TRY or TRX unit.

TRY & TRX

Maintaining the TRY/TRX

Moore Industries suggests a quick check for terminal tightness and general unit condition every 6-8 months, depending upon the severity of conditions. Things such as ambient vibration, corrosive atmospheres, extreme heat or cold, etc., can play a role in shortening the service life of any piece of electronic equipment.

IMPORTANT:

Always adhere to any site requirements for

programmed maintenance.

T roubleshooting the TR Y/ TRX

If a transmitter’s performance begins to deteriorate and a physical check of the installation uncovers no adverse conditions or damage, remove the offending unit from service and reperform the Conﬁguration Procedures from earlier in this manual.

“Table Data Invalid”

If there is a broken or loose communication wire, ambient electronic noise, or a problem with the memory chip inside the transmitter, this message may appear.

To ﬁx the condition, make sure that the desired operating parameters are displayed on the Conﬁguration Screen, and click on the “Prog” (Program) button. This should override the corrupt conﬁguration information in unit memory and reset the parameters correctly.

Contacting Customer Support

Moore Industries is recognized as the industry leader in delivering top quality to its customers in products and services. We perform a battery of stringent quality assurance checks on every unit we ship. If any Moore Industries product fails to perform up to rated speciﬁcations, call us for help. Our highly skilled staff of trained technicians and engineers pride themselves on their ability to provide timely, accurate, and practical answers to your process instrumentation questions.

Conﬁguration Software Error Messages

Data ﬁelds on the Conﬁguration Main Screen can change color or appearance in some way to indicate that an attempt is being made to create a nonstandard or ill-advised condition in the Conﬁguration File.

“Zero or Full Scale Outside Conformance Range”

Setting thermocouple input parameters to zero or full scale values that fall outside the published ISA thermocouple tables will cause this error message to appear on screen.

This condition is “downloadable” to a TRY or TRX. It is intended to provide the user with the ability to monitor general trends on the input, functioning within the rated accuracy whenever input is within the conformance range, but inherently less accurate outside the range.

“Reverse Output”

Setting the parameter for “Input Zero” numerically above the parameter for “Input Full Scale” causes this message in the “Output” section of the Conﬁguration Screen. This condition is downloadable to the unit, and causes transmitter output to rise proportionally in response to a drop on the input, and to fall proportionally as the input rises.

Factory phone numbers are listed on the back cover of this manual.

If problems involve a particular TRY or TRX, there are several pieces of information that can be gathered from the installation before the factory is called that will help our staff get the necessary answers in the shortest time possible. For the fastest service, gather:
