STZ

Functional Safety Dual Input Smart HART® Temperature Transmitter

Section 1 - Introduction

The Moore Industries’ Functional Safety HART Temperature Transmitter (STZ) is designed and

manufactured to provide a high level of availability for safety critical applications and for use as a
component part of a safety instrumented system.

This is the user’s manual for Moore Industries’ STZ

Transmitters. It contains all of the information needed to congure, install, operate and maintain

the instruments.

Overview

The STZ has the ability to accept one or two sensor inputs. The output of the STZ can be

configured to reflect either sensor 1, sensor 2, average, differential, backup, low or high select.
In backup, the STZ automatically switches to the secondary sensor input if the primary sensor

fails; either sensor can be selected as the primary sensor. This substantially increases the

overall reliability of the unit. Upon switching to the secondary sensor, an alert is displayed on
the transmitter’s LCD (HP version), and is available via the HART “additional status” diagnostic
bit. If a sensor fault occurs while the STZ is making a differential or average measurement, the
transmitter will drive the analog output upscale, downscale, preset value, or will hold last output.

The STZ has enhanced device intelligence which includes sensor drift, corrosion detection,

range alarms and device diagnostics. These can check and alert the user when thermocouples

fail unexpectedly, resistance thermometers exceed set parameters or the device has failures. A
more detailed explanation of these features is provided later in this section. For more information

on the STZ diagnostics refer to tables in Section 6.

Programmable Smart HART Temperature

SECTION 1

HART 7 compliance provides device conguration via DD, HART diagnostic data and exception

based reporting. In addition a DTM is provided to enable programming and monitoring with any

FDT compliant host or program such as PACTware.

To prevent unauthorized or accidental reconguration of the STZ while it’s performing its safety
function, it has an added security feature to allow users to set HART communication into a Read
Only or Disable mode. In Read Only mode, the STZ responds to HART7 commands to access

device variables and diagnostic status but does not allow any changes to be made to the unit

conguration. In Disable mode, all HART messages sent to the unit are ignored and no HART

messages are sent from the unit.

The STZ HP model has an additional feature, an easy-to-read customizable display.

The STZ [DIN] is also available with an AIS option which allows direct connection of sensors

from an intrinsically safe area. See Section 3 Installation and Wiring for more information

May 2019

The input field can also specify the specific sensor in a temperature transmitter assembly (see

RTI series data sheets for more information). If a second sensor is required in the assembly then

this needs to be ordered separately.

Note: While the STZ will accept a dual input sensor conguration the following limitations apply
only when using two input sensors:

STZ [HP] – 2-wire and/or 3-wire sensors. 4-wire sensors (RTDs) cannot be used.
STZ [DIN] – (see gure 3.2) 2-wire and/or 3-wire sensors. 4-wire sensors (RTDs) cannot
be used.
STZ [HPP] – (see gure 3.4) Sensor 1 can be congured as 2-wire or 3-wire sensor.
Sensor 2 is then restricted to a 2-wire sensor.

OUTPUT

4-20MA

Isolated from Input, with HART digital data pass-through.

POWER

12-42DC

The STZ is a 2-wire, loop powered instrument. It is powered either by an external

12-42Vdc power supply, or by a DCS (or PLC) input channel that provides power (12-42Vdc) to

the loop.
12-30DC
To specify units for installation in intrinsically safe areas, specify the 12-30Vdc.
This option is not applicable to DIN housing.

Measurement Modes and Device Variables

The STZ can support one or two sensor inputs. With one input it provides an output which is

proportional to the input with options for trimming, custom linearization and scaling. With two

sensor inputs there are many other measurement modes:
Single Measurement - Sensor 1 or Sensor 2 can be selected
Backup Measurement - Sensor 1 fail to Sensor 2 or Sensor 2 fail to Sensor 1. If the primary

SECTION 1

sensor fails the secondary sensor will continue to drive the analog output without any

interruption and a HART status flag is set.

Average Measurement - This will output the average value of Sensor 1 and Sensor 2.
Differential Measurement - Select from

-Differential: S1-S2

-Differential: S2-S1

-Absolute Differential: |S1-S2|

Low Select and High Select Measurements - This will output the larger or smaller

measurement of Sensor 1 or Sensor 2.

User’s Manual

238-760-00K

For both single sensor and two sensor inputs there are many other variables, known as Device
Variables, that are calculated from the inputs. Most HART commands use variables known as
Dynamic Variables. The Device Variables need to be assigned or ‘mapped’ to the Dynamic
Variables.

The tables below define the Device Variables and Dynamic Variables.

To select the measurement which appears on the Analog Output, the relevant Device Variable
must be assigned to the PV (Primary or Process Variable). By default, Sensor 1 (SEN1) is
assigned to the PV.

Note: To use a calculated Device Variable, both sensors’ engineering units (EGU) must be

compatible (i.e. the same or both temperature units). If a calculated Device Variable has
dierent engineering units (EGU) from the Sensors’ EGU, scaling will need to be used to
change the units.

SECTION 1

HART Broadcast Messaging (Burst Mode)

The STZ supports enhanced broadcast messaging more commonly referred to as burst mode.

When set to burst mode, the STZ will proactively send out messages instead of waiting for the
host to request them. This enables event driven communication (high, low, deviation of signal or
change in status) and/or timed communication (every 20 seconds) to the host. Up to 3 different
burst messages may be configured in the STZ. Please see section 4 for more information on

burst mode configuration

Note: When using burst mode in the STZ, the host must also be congured to communicate in

burst mode.

HART Modes

The STZ has an added security feature to allow users to set HART communication into a Read
Only or Disable mode. In Read Only mode, the STZ responds to HART7 commands to access

device variables and diagnostic status but does not allow any changes to be made to the unit

configuration. In Disable mode, all HART messages sent to the unit are ignored and no HART

messages are sent from the unit.
These modes will prevent unauthorized or accidental reconfiguration of the STZ while it’s

performing its safety function. HART communication is in Full Access mode by default and the
mode can only be changed using FDT/DTM with the USB communication cable connected to the
STZ. The HART mode cannot be read or changed using HART communication.

STZ

Functional Safety Dual Input Smart HART® Temperature Transmitter

Sensor Diagnostics

As part of the enhanced device intelligence, the STZ performs Total Sensor Diagnostics. This
can save you downtime by letting you know when a problem occurs, what type and it’s location.

Some of these diagnostics such as drift alert and corrosion detection can also be used for
predictive diagnostics to warn of future problems. This allows for planned sensor replacement
and minimal process interruption.

User’s Manual

238-760-00K

May 2019

SECTION 1

Range Alarms

The STZ implements 4 independently congurable Range Alarms. Typical applications are
outside of range detection, in range detection and sensor drift.

Range Alarms (RA) can be used to detect if a Device Variable is inside or outside of an arbitrary
user specied range. Any Device Variable can be used as the source, including the RJC
Temperature, Loop Current, and Percent of Range (POR). The alarm can be set to a warning
(set a HART status bit) or an alarm (sets a di󰀨erent status bit, plus AO fail response). It can also
be congured as latching or non latching.

100 -

0 -

Note: If a Range Alarm Response is set to Alarm, the AO will always perform a fail response

even if the source Device Variable is not assigned to the PV. Setting the Range Alarm
Response to Warning will not aect the AO.

Functional Safety Dual Input Smart HART® Temperature Transmitter

Sensor Drift Detection

Drifting in sensors occurs from a number of di󰀨erent causes including environmental
contamination, vibration, and extreme temperature uctuations. This can lead to false sensor

readings. The STZ

monitor the absolute di󰀨erential between two sensors (e.g., RTD & T/C or two RTDs or

T/Cs) at the same point. This method can provide a range alarm warning or alarm to indicate
that there is an issue with one of the sensors. See Chart below for clarication.

In this example a Range Alarm is set with the Absolute Di󰀨erential as the source. An out of
range warning or alarm is congured with the low and high limits set to 0C° to 5C° respectively,
creating an alarm when Sensor 1 and Sensor 2 readings drift apart by more than 5C°.

Note: When setting the drift limit please allow for sensor tolerances and dierences in sensor

response times to avoid false drift alerts.

Corrosion Detection

Corrosion of the sensor connections is primarily caused by oxidation or electrolysis which can
lead to inaccurate readings with RTD measurements. The STZ is able to detect corrosion on 3W
or 4W RTDs by measuring the change in compensating lead wire resistance between terminals 3
and 4 providing an alert when preset value limits are exceeded.

Additionally the STZ monitors the status of T/C circuits. High resistance values in T/C circuits
could indicate a potential impending T/C burnout.

SECTION 1

To setup Corrosion Detection, the user captures the nominal sensor resistance value and sets
the Warning and Alarm limits. These can be set at di󰀨erent levels or the same level for both.
See chart below for clarication.

Selecting Warning will set a fault message on the STZ display and send a HART message to any
HART Handheld or HART monitoring HOST. In addition an alert will be sent to any FDT host that
is communicating with the transmitter. Selecting Alarm will also drive the Analog output to Fail
Mode if the sensor is assigned to the PV. If the unit is in backup mode, and the primary sensor
has a corrosion alarm, the PV will switch to the backup sensor.

Broken Wire Detection

During operation, the STZ sends random microamp pulses through input wiring to check for
broken wiring or a burned out sensor. By default the broken wire detection is always enabled,

and this feature is essential to ensure that dangerous failure of the sensor or signal input is
detected by the STZ and consequently alarmed.

If the STZ detects a broken wire or burned out sensor during operation, the transmitter sets the

output upscale or downscale to warn of trouble. The transmitter is able to identify the sensor

wire(s) causing the problem and indicates the fault as a message to the HART Handheld/FDT
HOST, STZ display (HP version) and by setting a HART status bit. Specic error messages

eliminate the work of removing the sensor or checking all lead wires to diagnose a problem. This
feature is especially valuable during startup.

Additionally the STZ has another feature referred to as BW (Broken Wire) Holdo󰀨 Time. This

allows users to add an additional time delay before the broken wire diagnostic alert is reported.

When enabled, a Broken Wire delay of 0-60 seconds can be set. This feature prevents the
transmitter from going into a fault state when intermittent high levels, or spikes, of extraneous

plant noise is conducted onto the sensor leads.

Calibration

Every STZ is calibrated to our specifications prior to delivery to our customers. We recommend

that you check the calibration every year and re-calibrate only when necessary. Please refer
to the Long Term Stability Table in Section 8 of this manual. Calibration by the end user can be

performed in the field by capturing or trimming the input and/or trimming the analog output.
Sensor trimming increases the measurement accuracy of your instrument by matching the

reading of its actual input to its scaling. The STZ offers the use of a trimming feature that can be

SECTION 2

accessed using a HART Communicator, a HART Host, or an FDT Host (such as PACTware).

Likewise, output trimming increases the measurement accuracy of the STZ by calibrating its
analog output to the device that is receiving the output (such as a DCS). This ensures that the

output of the STZ is being correctly interpreted.

This will help you to be sure to apply the correct input with which to trim your STZ. By example:
If the Sensor 1 Measure Mode is “RTD 4 wire” and the Sensor 1 Input Type is “Pt 3850 1000
ohm” and Sensor 1 EGU is “deg F” then you should be using an accurate resistance source
(such as a decade box) to emulate the 4-wire, Pt 3850, 1000Ω RTD and use the Fahrenheit
temperature tables to source the correct resistances for your specic temperature range. Be
sure to also check the HART Communicator’s Online Menu to see your instrument’s PV LRV

Figure 2.10. Sensor 1 Trim

The Trim Mode can be set for One Point or Two Point. If interested in obtaining the best
accuracy at one temperature point, choose the One Point mode. The most common Trim Mode
is Two Point. This mode yields greater measurement accuracy over a temperature range by
trimming points on each side of a specic range or by trimming at your Zero and Full scale
values (as congured in the Ranging and Mapping screen). The below example outlines a Two
Point trim at the Zero and Full scale points..

SECTION 2

Note: The current Sensor 1 Reading is -2.53° C.

Perform the following steps -

1. Set Trim Mode to “Two Point”

2. Set your input resistance to match your Sensor 1 Zero point. By example – If your Sensor 1

Zero point is 0° C the input you apply to the instrument will be 1000.00Ω.

3. Enter the Sensor 1 Zero value into the eld entitled Desired Trim Point Value. For my example

I will be entering 0 (as my range is dened as 0-100°).

4. When your reading stabilizes press the Trim Lower Point button and your Sensor 1 Reading

should now read the correct Trim Point Value (0 in this example).

5. Enter the Sensor 1 Full value into the eld entitled Desired Trim Point Value. For my example I

will be entering 100 (as my range is dened as 0-100°).

6. Set your input resistance to match your Sensor 1 Full point. By example – If your Sensor 1

Full point is 100° C the input you apply to the instrument will be 1385.00Ω.

7. When your reading stabilizes press the Trim Upper Point button and your Sensor 1 Reading
should now read the correct Trim Point Value (100 in this example).

You can then perform Sensor 2 Trim if you are using two input sensors.

Your trim values will be automatically saved to your instrument.

The output of the STZ is accurately calibrated prior to delivery to our customers. However,

you may wish to trim the instrument’s analog output to match what you are reading on your

monitoring or control system. By example: if the STZ is putting out 12.0mA and your DCS is
reading 11.85mA you can trim the output of the STZ so that the two readings will match. Note:

SECTION 2

trimming of the analog output will not a󰀨ect the HART digital data.

To perform output trimming set up your STZ as shown in Figure 2.11.

Select the Custom Calibration/AO Loop Current Test/Trim option in the conguration menu as
shown in Figure 2.12.

Figure 2.12. Custom Calibration/AO Loop Current Test/Trim

SECTION 2

The points that will be used for trimming will be the “AO Zero” and the “AO Full” that were
congured earlier. For my example these two points will be 4mA (AO Zero) and 20mA (AO Full).

In the “Output Trim” section of the Parameter screen Set Output to “Lower Output Range”. This
will set the instrument’s output to 4mA. Use your voltmeter to read the voltage drop across the
250Ω resistor and calculate the actual current going through the resistor.

Example: A voltage reading of 1.08v equates to 4.32mA (1.08V ÷ 250Ω = 4.32mA). Enter this
value in the Measured Output Current box and then push the “Trim” button.

Now, select the “Upper Output Range”. This will set the instrument’s output to 20mA. Use your
voltmeter to read the voltage drop across the 250Ω resistor and calculate the actual current

going through the resistor.

Example: A voltage reading of 4.91v equates to 19.64mA (4.91V ÷ 250Ω = 19.64mA). Enter
this value in the Measured Output Current box and then push the “Trim” button.

Now that the 2-point output trimming has been done you can test the results by entering an
output value in the “Set Current to” box. Enter 4 (for 4mA) in the box, select the “Set” button and
the instrument’s output will go to 4mA and you can check for a 1V reading across the resistor.
You can then enter 20 and check for a 5V reading across the resistor.

There is no need to press the “Apply” button as all trim changes take immediate e󰀨ect.

Note: When complete BE SURE to press the “Clear” button to return control of the output back

to your STZ.

Connect your STZ as shown if gure 2.13. See Section 4 of this manual to congure your STZ
as appropriate for your application. If possible, use the exact temperature sensor (RTD or

thermocouple) that you will be using in your nal application. Apply power to the

STZ and see that it is reading the correct ambient temperature and providing the correct output
for the given input.

Example: If your STZ is congured to measure a temperature range of 50-100° F and is
now on your test bench and is reading an ambient temperature of 72° then you should
expect an output of 11.04mA.

If it is not feasible for you to use the actual temperature sensor for your bench test, or if your
desired temperature range is nowhere near your ambient temperature, then use a temperature
simulator (such as a Fluke 725 or similar) to provide your input.

Once your bench setup is complete you can now use your FDT/DTM software to check the
transmitter’s dynamic variables and analog output. If using PACTware you can use the
“Measured value” menu command to view the transmitter’s real time values (see Section 5.24 of

this manual).

Note: Make sure to calibrate and bench check the instruments prior to installation. Also,

install all instruments in their intended application before making any electrical connections.
For DIN rail mounted instruments, allow enough room for pivoting instruments vertically on the
rail for removal in applications involving multiple banks of units. To remove the unit from the
DIN rail you will need a simple tool such as a straight blade screwdriver. Insert the blade of
the screwdriver into the cavity at the bottom of the locking mechanism and rotate it. This will
release the locking mechanism from the DIN rail and allow you to remove the unit.

Electrical Connections

When installing any Moore Industries product, always follow all local regulations and standards
for grounding, shielding, and safety.

WARNING: Terminals on this unit may be connected to hazardous voltages. Before making

ANY connections to this unit, always remove power from the loop or instrument power
terminals.

Installation Category

All terminals are rated CAT I.

Equipment Ratings

The STZ does not generate hazardous voltages, they provide a low voltage (0-1V) input and a
4-20mA output. Products connected to the STZ should be designed to receive this type of input.

WARNING: If this unit is used in a manner not specied by Moore Industries, the protection

provided by the equipment may be impaired.

Power Supply Wiring

All power connections should be made with 14 or 16 AWG (2mm2 or 1.3mm2) wire. The end
of each conductor should be stripped no more than 0.25in (7mm). 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. Tighten the screws on the terminal block to 4.4 - 5.3 lbf/in2 (0.5 - 0.6 N/m2).

Protective Earth Conductor

The Protective Earth Conductor shall be of equal or larger size wire than the other two power
conductors. The Protective Earth Conductor shall be the first conductor connected to the unit

when the unit is being wired. It shall be the last conductor removed when the unit is being un­wired.

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 un-shielded input and output signal wiring should be 2 inches.

SECTION 3

Note: Some of Moore Industries’ instruments can be classied as receivers (IPT2, IPX2, etc.)

and some can be classied as transmitters (TRX, STZ etc.) while some are both a receiver and
a transmitter (SPA2, 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 Certification-related Guidelines

The grounding and wiring practices described above must be followed in order for the unit(s) to

meet the requirements set forth in EMC standard EN61326.

Section 4 - Conguration

The STZ can be congured using a HART communicator, HART host or a PC running an FDT/
DTM program. All functions can be congured using either method with the exception of custom
curves which cannot be generated or imported using the HART communicator. However, once
custom curves have been saved in the unit they can be selected using the HART Communicator.

The following Conguration Overview is applicable to both programming methods. The

SECTION 4

remainder of this Section details programming with a HART communicator. For details of
conguring using FDT/DTM please refer to Section 5.

Configuration Overview

The following will be an overview of configuration for the STZ.

User’s Manual

238-760-00K

May 2019

Usage of the STZ

• Single Sensor

• Dual with “identical” sensors

• Dual with diverse sensors.

When both sensors are being used, and they both produce the same units (in SEN1 and SEN2)

they can be combined in the derived variables. The inputs can be either identical (e.g. the same

exact RTD) or be different sensors, producing the same measurement.

If both sensors are being used and they produce different units, then the derived variables cannot

be used.

Note: To use a calculated Device Variable, both sensors’ engineering units (EGU) must be

compatible (i.e. the same, or both temperature units). If a calculated Device Variable has
dierent engineering units (EGU) from the sensors’ EGU, scaling will need to be used to
change the units.

Single Sensor

The STZ can be configured to use a single sensor. Follow these steps:

1) Configure the sensor

a. Use the “Configure Input Types” method to select SEN1, and to have SEN2 disabled

can be grouped into three general classifications:

b. Navigate to the Sensor 1 Configuration menu, and make any additional settings as needed

2) Specify Variable mapping - The only variables which can be mapped as Dynamic

Variables are: RJC T, and SEN1. In most cases, SEN1 should be used as the PV.

3) Configure the PV Range (PV URV and LRV).

4) Configure the AO’s Range, limits, and fail response.

Note: A single sensor 4W RTD is the factory default conguration. (see Quick start guide for

details)

then scaling must be enabled here.

4) Configure the PV Range (PV URV and LRV).

5) Configure the AO’s Range, limits, and fail response.

Dual with Mixed Sensors

The STZ can be configured for use with two different sensors (for example, T/C and a RTD).

Note: While the STZ will accept a dual input sensor conguration the following limitations apply
only when using two input sensors:

STZ [HP] – 2-wire and/or 3-wire sensors. 4-wire sensors (RTDs) cannot be used.
STZ [DIN] (see gure 3.2) - 2-wire and/or 3-wire sensors. 4-wire sensors (RTDs) cannot
be used.
STZ [HPP] (see gure 3.4) – Sensor 1 can be congured as 2-wire or 3-wire sensor.
Sensor 2 is then restricted to a 2-wire sensor.

STZ

Functional Safety Dual Input Smart HART® Temperature Transmitter

The following additional features may also be useful:

Sensor Trimming

Sensor Trimming increases the measurement accuracy of your instrument by trimming 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.

SECTION 4

Trimming can be applied to one or both sensors (SEN1 & SEN2).

Running Average Filter

This function filters the sensor input signal with a user-selected range between 1 and 16. A
higher Running Average Filter setting provides smoother output transitions; however, increases
response time. Conversely, a lower setting provides a faster response time, but may seem more

unstable.

Filter

This setting is used to configure the input filter. The 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.

Scaling

Scaling can be applied to any Device Variable including Sensor 1 and Sensor 2. It provides for a
linear transformation from the Device Variable’s units to any other engineering unit (EGU). Two
points are specified (Input minimum, Scale minimum) and (Input maximum, Scale maximum).

User’s Manual

238-760-00K

May 2019

When scaling is enabled, no unit checking is done. It is possible to convert the value from one
unit to another by configuring for unity scaling eg, (0, 0 and 100, 100). However this should be

unnecessary.

Custom Curve (Advance Settings)

The unit provides the capability to program 4 independent custom curves (CC1-4) which can be
applied to any available Device Variable to define a non-linear scaling. Each Custom Curve can
contain up to 128 pairs (X, Y) where X is the input and Y the output.

Custom Curves cannot be entered using the HART Communicator, they must be entered via the
FDT/DTM. However, once a custom curve has been saved in the unit it can be assigned and
enabled or disabled using the HART Communicator.

PV Settings

There are a few settings which apply specifically to the PV:

• PV Upper Range Value (URV) and Lower Range Value (LRV): Used to scale the PV to

the Percent of Range and Loop Current values. These settings are independent from any

other scaling settings.

• 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

damping time setting is the time PV takes to make a 63% change in response to a step

change.

STZ

Functional Safety Dual Input Smart HART® Temperature Transmitter

Analog Output

The system will scale the PV from its LRV/URV (Lower Range Value / Upper Range Value) range
to the AO’s Zero/Full range. As the PV exceeds this range, the AO will continue linearly until it
reaches the AO URV (AO Under Range Value) or AO ORV (AO Over Range Value), where it
“flatlines.” At this point, the output is considered saturated, and will be limited to that value.

If the PV’s data quality goes BAD, or a system error is detected which should result in the
programmed fail response, the AO will respond as configured by either:

• Fail High to 23.6 mA

• Fail Low to 3.6 mA

• Hold Last Value

• Fail to a Preset Value, configurable between 3.6 and 23.6mA

Analog Output Trimming

AO Trimming increases the accuracy of your instrument by calibrating its analog output to the

device that is receiving the output. This ensures that the instruments are matched to each other.

Display (STZ [HP] only)

All dynamic and additional device variables in the transmitter can be selected for display. If none
are selected, then the unit will behave as though the PV is marked for display. A “screen” of data
includes the two main rows of characters on the display. Normally, a floating point value is shown
on the top with a text message on the bottom row. Some items require more than one screen to
be displayed. Each screen is shown for 2 seconds. If the value being displayed changes, it will

be updated while that screen is being shown.

Functional Safety Dual Input Smart HART® Temperature Transmitter

HART Broadcast Messaging (Burst Mode)

When set to burst mode, the STZ will proactively send out messages instead of waiting for the
host to request them. This enables event driven communication (high, low, deviation of signal or
change in status) and/or timed communication (every x seconds) to the host.

Note: When using burst mode in the STZ, the host must also be congured to communicate in

burst mode.

User’s Manual

238-760-00K

May 2019

SECTION 4

Up to 3 different burst messages may be configured independently in the STZ. For each burst

message the following parameters need to be configured:

HART Command – determines which parameters are sent in the message

Update Periods – specifies the minimum and maximum time between messages

Trigger – determines what triggers a message to be sent to the host

Slot 1-8 – For HART commands 9 and 3 only, select the device variables for the message

The following HART commands can be selected for the burst message:

Command Variables in burst message Trigger Source

1 Primary Variable (PV) PV

2 Loop current and Percent of Range (POR) POR

3 Dynamic Variables and Loop Current PV

9 Device Variables with status Device Variable in Slot 1

33 Device Variables Device Variable in Slot 1

48 Additional Device Status Status bits

Update Periods: The Update and Maximum Update periods determine the minimum and
maximum time interval between each message. The update periods can be set to the following

values:

0.5, 1, 2, 4, 8, 16, 32, 60-3600 seconds

The actual frequency of messages sent will be determined by the update periods and trigger
mode.

If the trigger mode is set to Continuous, then the message will be sent every x seconds where x is
the Update period.

If the trigger mode is set to any other value (i.e. it is looking for a trigger) then the message will be

sent every x seconds (update period) if the trigger condition is met. If the trigger condition is not
met then a message will be sent every y seconds where y is the Maximum Update period. This
ensures that the device and host communicate regularly (once per hour if y is set to the maximum

value of 3600 seconds).

*Units must match the trigger source units. If the units do not match then trigger mode becomes inactive.

** The trigger level can be any value in the trigger source range.

*** For continuous and level modes the trigger level and units are not applicable. The level is set to 1.0 by
default.

In all cases, burst messages are sent every x seconds (Update Period) if the trigger condition is
met. If the trigger condition is not met, the update time will drop to the Maximum Update Period.

SECTION 4

Slots 1-8: For commands 9 and 33, the Device Variables which will be sent in the message
need to be selected. By default all slots are set to ‘Not Used’. Only Slots 1-4 can be assigned for
Command 33.

If a trigger condition is set, Slot 1 must have a Device Variable assigned and this will be used as

the trigger source.

SECTION 4

HART Modes

HART communications can be set to Full Access, Read Only and Disable modes.

In Read Only mode, the STZ responds to HART7 commands to access device variables and

diagnostic status but does not allow any changes to be made to the unit configuration. In Disable

mode, all HART messages sent to the unit are ignored and no HART messages are sent from the

unit.
These modes will prevent unauthorized or accidental reconfiguration of the STZ while it’s

performing it’s safety function. HART communications is in Full Access mode by default and the
mode can only be changed using FDT/DTM with the USB communications cable connected to
the STZ. The HART mode cannot be read or changed using HART communication.

Sensor Diagnostics

Sensor Drift Alert using Range Alarms and Sensor Corrosion Detection can also be used for

predictive diagnostics to warn of future problems.
Broken Wire Holdoff Time allows you to add an additional time delay before a sensor broken

wire is reported which provides some noise immunity and prevents false alarms caused by other
factors that may be misinterpreted as Broken Wire.

Please refer to Section 1 for more detailed information on Sensor Diagnostics.

Input Quality Alarms

The STZ also allows the user to determine how certain types of input quality issues are handled

and how they can affect the Device Variables, Dynamic Variables and AO. There are 3 different
quality alarms: Measurement out of Conformance Range, Allow Limited and Allow Dropping. See

Section 6 for more information.

These flags control which Dynamic Variables (PCT, AO, PV, SV, TV, QV) are displayed. By
default PV is shown.

When PV, SV, TV, or QV are selected for display, each will result in three screens.

123.45 / Dynamic Var Name

123.45 / Source Device Var Name

123.45 / Units

For example: If the PV is 123.45 OHMS being sourced from the Average Device Variable, the

following will be shown:

123.45 / PV

123.45 / AVG

123.45 / OHMS

When the Percent of Range or Loop Current are selected for display, each will be shown using

two screens:

If there is a problem with the underlying Device Variable, only one screen will be shown:

BADDQ / Dynamic Var Name

In this last case, the nature of the error will be shown separately.

Decimal Places [Auto]

This setting (0-3, AUTO) controls the maximum number of decimal places shown. For example, a
setting of AUTO, will display 1.2345, or 12.345. Depending on the magnitude of the whole portion
of the number, the decimal point may be forced to the right. If 3 Decimal places are selected,

1.234 will be shown. However the DP will be moved to allow 123.45 to be shown.

AO Trim– Directs you to a sub-menu. Here you can select Reset Trim, Trim Zero or Trim Full.
AO Trim Reset– Directs you to a sub-menu. Here you can select No or Yes.
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.

Input Simulation – Allows you Clear or Set a simulated Input.
S1 Corrosion Detection – This captures the nominal resistance value of Sensor 1, then

allows setting 2 threshold resistances (warning and alarm) to identify when corrosion
occurs. This applies only to Thermocouples and 3W and 4W RTDs. See section 1 for
more information on Corrosion Detection.

S2 Corrosion Detection – This captures the nominal resistance value of Sensor 2, then allows

setting 2 threshold resistances (warning and alarm) to identify when corrosion occurs.
This applies only to Thermocouples and 3W and 4W RTDs. See section 1 for more

Section 5 -

Software

Before reading this section on the FDT/DTM conguration, please read the Conguration
Overview at the beginning of Section 4 for general information on conguring the STZ.

This section provides information on conguring the STZ using a PC with PACTware

(an FDT frame application). For users who already have an FDT Frame Application, all the

SECTION 5

following information is still relevant except for the PACTware installation. For more information
on FDT/DTM please refer to www.fdtgroup.org.

FDT Frame Application

Moore Industries has always provided manufacturer-specic programs to operate our eld
instruments to the full extent. STZ will require the use of an FDT frame application, which allows
conguration and adjustment of any and all eld instruments ,which have a DTM. For users who
do not already have an FDT frame application, Moore Industries provides PACTware.

An FDT frame application, such as PACTware, is a PC program which interfaces with individual
software modules for instrument operation. This interface is regarded as the FDT; the individual

software modules for instrument adjustment are called DTMs (Device Type Manager) . This

conguration makes user-friendly adjustments possible because the interface for instrument

adjustment is optimally adapted to each instrument.

Furthermore, you can communicate with an FDT frame application not only via HART but

also via any other communications protocols. Moore Industries provides a proprietary serial

communication DTM named MISP (Moore Industries Serial Protocol), which allows faster device
conguration using our USB communication cable. The MISP DTM will be provided in addition
to the STZ Device DTM. In the FDT frame application, these individual instrument DTMs and

communication DTMs are installed as required.

Conguration using FDT/DTM

FDT/DTM Software Installation

In order to get started you will need to either install the PACTware software and DTMs or just
install the DTMs (if you already have an FDT frame application installed). All the les you need

can be found on our website www.miinet.com.

Note: While the STZ will accept a dual input sensor conguration the following limitations apply
only when using two input sensors:

STZ [HP] 2-wire and/or 3-wire sensors. 4-wire sensors (RTDs) cannot be used.
STZ [DIN] (see gure 3.2) - 2-wire and/or 3-wire sensors. 4-wire sensors (RTDs) cannot be

used.

STZ [HPP] (see gure 3.4) – Sensor 1 can be congured as 2-wire or 3-wire sensor. Sensor 2

is then restricted to a 2-wire sensor.

Parameters Input Congure Sensor Types

Sensor 1 and 2 Broken Wire Holdoff (0.0-60.0secs): This allows users to add an additional

time delay before broken wire is detected. When enabled, a Broken Wire delay of 0-60 seconds

can be set which provides some noise immunity and prevents false alarms caused by other
factors that may be misinterpreted as Broken Wire.

1. Enter the Broken Wire Holdoff value you desire.
Sensor 1 and 2 Running Average Filter Setting (1-16) : This function is for filtering the input

signal. The STZ has a running average filter with a user-selected range between 1 and 16.

1. Enter the Running Average Filter Setting value you desire.

Note: A higher Running Average Filter setting provides smoother output transitions; however,

increases response time. Conversely, a lower setting provides a faster response time, but may
seem more unstable.

Ranging and Mapping

The Ranging and Mapping menu will allow you to view current Device Variable assignment/

mapping to PV, SV, TV, and QV. It will also allow you to designate or change each one as
needed. To do so enter the Change Variable Mapping menu option. In this menu you will
select from RJC Temperature, Sensor 1, Sensor 2, Backup 1-2, Backup 2-1, Average,
Dierential 1-2, Dierential 2-1, Absolute Dierential, Low Select, or High Select to

each variable (PV, SV, TV, & QV).

In addition to mapping the Dynamic Variables, you can also set the PV lower range and upper
range values to AO 0-100% and 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 damping time setting is the time PV takes to make a 63% change in

response to a step change.
