ST 3000 Smart Transmitters
About the transmitter
The ST 3000 Smart Transmitter comes in a variety of models for measurement applications involving one
of these basic types of pressure:
•
Differential Pressure
•
Gauge Pressure
•
Absolute Pressure
The transmitter measures the process pressure and transmits an output signal proportional to the measured
variable over a 4 to 20 milliampere, two-wire loop. Its major components are an electronics housing and a
meter body as shown in Figure 1 for a typical differential pressure model transmitter.

Functional block diagram
Besides the process variable (PV) output, the transmitter also provides its meter body temperature as a
secondary variable (SV) which is only available as a read-only parameter through the communicator
interface. See Figure 2.

Each series includes several models to meet various process pressure measurement and interface
requirements. Each transmitter comes with a nameplate located on the top of the electronics housing that
lists its given “model number”. The model number format consists of a Key Number with several Table
selections as shown below.
Table IV
XXXX
You can quickly identify what series and basic type of transmitter you have from the third and fourth digits
in the key number. The letter in the third digit represents one of these basic transmitter types:
A = Absolute Pressure
D = Differential Pressure
F = Flange Mounted
G = Gauge Pressure
R = Remote Seals
The number in the fourth digit matches the first digit in the transmitter Series. Thus, a “1” means the
transmitter is a Series 100 and a “9” is a Series 900.
For a complete breakdown of the Table selections in your model number, please refer to the appropriate
Specification and Model Selection Guide that is provided as a separate document.
ATTENTION
Be aware that previous vintages of the ST 3000 transmitter with designations of Series 100,
Series 100e, Series 600, and Series 900 have been supplied at various times since the ST
3000 was introduced in 1983. While all these transmitters are functionally alike, there are
differences in housing and electronics design.
This manual only applies for Series 100, Release 300 and Series 900, Release 300
transmitters furnished with the HART communications option (option HC). Release 300
transmitters can be identified by the “R300” designation on the nameplate.

Transmitter adjustments
Except for optional local zero and span adjustments, the ST 3000 has no physical adjustments. You need a
HART communicator to make any adjustments in a ST 3000 with the HART communications option.
Transmitter operator interface
The HART communicator (Model 275) is connected to the loop wiring of the ST 3000 transmitter for direct
communication with the transmitter. The hand-held communicator “talks” with a transmitter through serial
digital signals over the 4 to 20 milliampere line used to power the transmitter. A request/response format is
the basis for the communication operation. The transmitter’s microprocessor receives a communication
signal from the communicator, identifies the request, and sends a response message.
Figure 3 shows a simplified view of the communication interface provided by the communicator.

Communicator Purpose
The communicator allows you to adjust transmitter values, or diagnose potential problems from a remote
location such as the control room. You use the communicator to:
•
Configure: Define and enter the transmitter’s operating parameters.
•
Monitor: Read the input pressure to the transmitter in engineering units and the transmitter’s output in
milliamperes or percent.
•
Display: Retrieve and display data from the transmitter or the communicator’s memory.
•
Check current output: Use the transmitter to supply the output current desired for verifying analog
loop operation, troubleshooting, or calibrating other components in the analog loop.
•
Troubleshoot: Check status of transmitter operation and display diagnostic messages to identify
transmitter, communication, or operator error problems.
ATTENTION
Throughout this manual, procedures are given on how to use the HART communicator to
configure, operate and troubleshoot the ST 3000 transmitter. Keystrokes and screen displays
for the HART communicator are referenced in these procedures. However, additional
information on communicator operation is found in the product manual supplied with the

About this section
This section provides information about installing the ST 3000 transmitter. The topics in this section
include:
•
Mounting the ST 3000 transmitter - various mounting methods are described and can be used
depending upon the transmitter type.
•
Piping the transmitter to the process – connecting the transmitter meter body to the process piping or
tank connection.
•
Wiring the transmitter – connecting the loop wiring and ground conductors to the transmitter, and
information is given on connecting local and remote indicating meters to the transmitter.
Mounting ST 3000 Transmitter
Summary
You can mount all transmitter models (except flush mount models and those with integral flanges) to a
2-inch (50 millimeter) vertical or horizontal pipe using our optional angle or flat mounting bracket, or a
bracket of your own. Flush mount models are mounted directly to the process pipe or tank by a 1” weld
nipple. Those models with integral flanges are supported by the flange connection.
Figure 7 shows typical bracket mounted and flange mounted transmitter installations for comparison.
Dimensions
Detailed dimension drawings for given transmitter series and types are listed in Section 13 in this manual
for reference. Note that abbreviated overall dimensions are also shown in the specification sheets for the

Mounting Transmitters with Small Absolute or Differential Pressure Spans
To minimize positional effects on pressure measurement and calibration (zero shift), take the appropriate
mounting precautions that follow for transmitters with small pressure spans.
Absolute Pressure and In-line Transmitters
For absolute pressure and inline transmitters you must ensure that the transmitter is vertical when mounting
it. You do this by leveling the transmitter side-to-side and front-to-back. See Figure 8 for suggestions on
how to level the transmitter using a spirit balance.

Figure 8 Leveling Transmitters
CAUTION
The mounting position of a model STA122 or STA922 Absolute Pressure Transmitter or a
model STD110 Draft Range Differential Pressure Transmitter is critical as the transmitter
spans become smaller. A maximum zero shift of 2.5 mm Hg for an absolute transmitter or 1.5
in H2O for a draft range transmitter can result from a mounting position which is rotated 90
degrees from vertical. A typical zero shift of 0.12 mm Hg or 0.20 in H2O can occur for a 5
degree rotation from vertical.
Differential Pressure Transmitters
For a transmitter with a small differential pressure span (Model STD110, for example), you must ensure
that the transmitter is vertical when mounting it. You do this by leveling the transmitter side-to-side and
front-to-back. See Figure 8 for suggestions on how to level the transmitter using a spirit balance. You must
also zero the transmitter by following the steps in Table 7 below.

Continue with the remaining installation tasks.
Flange mounting
Transmitters that are furnished with integral flange connections (models STFxxx), are bolted directly to the
process flange connection. Figure 9 shows a typical installation for a transmitter with the flange on the high
pressure (HP) side so the HP diaphragm is in direct contact with the process fluid. The low pressure (LP)
side of the transmitter is vented to atmosphere (no connection).
To mount a flange mounted transmitter model, bolt the transmitter’s flange to the flange pipe on the wall of
the tank.
ATTENTION
On insulated tanks, remove enough insulation to accommodate the flange extension.
Once the transmitter is mounted, the electronics housing can be rotated to the desired
position. See Table 6, Step 4 for details.
It is the End User’s responsibility to provide a flange gasket and mounting hardware that are
suitable for the transmitter’s service condition.
To prevent degradation of performance in Flush-Mounted Flanged Transmitters, exercise care to
ensure that the internal diameter of the flange gasket does not obstruct the sensing diaphragm.
To prevent degradation of performance in Extended Mount Flanged Transmitters, ensure that
there is sufficient clearance in front of the sensing diaphragm body.

Piping Arrangements
The actual piping arrangement will vary depending upon the process measurement requirements and the
transmitter model. Except for flush, flanged and remote diaphragm seal connections, process connections
are made to ¼ inch or ½ inch NPT female connections in the process head of the transmitter’s meter body.
For example, a differential pressure transmitter comes with double-ended process heads with ¼ inch NPT
connections but they can be modified to accept ½ inch NPT through optional flange adapters. Some gauge
pressure transmitters may have a ½ inch NPT connection that mounts directly to a process pipe.
The most common type of pipe used is ½ inch schedule 80 steel pipe. Many piping arrangements use a
three-valve manifold to connect the process piping to the transmitter. A manifold makes it easy to install
and remove or rezero a transmitter without interrupting the process. It also accommodates the installation
of blow-down valves to clear debris from pressure lines to the transmitter.
Figure 13 shows a diagram of a typical piping arrangement using a three-valve manifold and blow-down
lines for a differential pressure transmitter being used to measure flow.

ATTENTION
• For liquid or steam, the piping should slope a minimum of 25.4 mm (1 inch) per 305 mm (1
foot). Slope the piping down towards the transmitter if the transmitter is below the process
connection so the bubbles may rise back into the piping through the liquid. If the transmitter
is located above the process connection, the piping should rise vertically above the
transmitter; then slope down towards the flowline with a vent valve at the high point.
• For gas measurement, use a condensate leg and drain at the low point (freeze protection
may be required here). See Appendix C for some suggested freeze protection solutions.
ATTENTION
Care must be taken when installing transmitters on hot processes. The operating temperature
limits for the device (as outlined in Table 3) must not be exceeded. Impulse piping may be
used to reduce the temperature of the process that comes into contact with the transmitter
meter body. As a general rule there is a 56 degree C drop (100 degree F) in the temperature
of the process for every foot of 1/2" uninsulated piping.

•
When measuring fluids containing suspended solids, install permanent valves at regular intervals to
blow-down piping.
•
Blow-down all lines on new installations with compressed air or steam and flush them with process
fluids (where possible) before connecting these lines to the transmitter’s meter body.
•
Be sure all the valves in the blow-down lines are closed tight after the initial blow-down procedure
and each maintenance procedure after that.

Wiring ST 3000 Transmitter
Summary
The transmitter is designed to operate in a two-wire power/current loop with loop resistance and power
supply voltage within the operating range shown in Figure 15. When option LP (lightning protection)
and/or remote smart meter are selected, the voltage drop for these options must be added to the basic
transmitter voltage of 10.8 V to determine VXMTR and RLOOP MAX. Additional consideration is required
when selecting intrinsic safety barriers to insure that the barriers will supply VXMTR MIN including the
required 250 ohms (typically within the barriers) for digital communications.
Transmitter Parameters:
RLOOP MAX = The maximum loop resistance (barriers plus wiring) that will allow proper transmitter
operation.
Therefore,
RLOOP MAX =
(VSUPPLY MIN – VXMTR MIN) ÷ 21.8 mA
Where,
VXMTR MIN =
10.8 V + VLP + VSM
VLP =
1.1 V, lightning protection option, LP
VSM = 2.3 V, remote smart meter
(Please note that VSM should only be considered if a remote smart meter
will be connected to the transmitter.)

ground the transmitter for proper operation, we suggest that you do so to minimize the possible effects of
“noise” on the output signal and provide additional protection against lightning and static discharge
damage. Note that grounding may be required to meet optional approval body certification. Refer to
Section 3, CE Conformity (Europe) Notice for special conditions.
Optional lightning protection (option LP) can be ordered for transmitters that will be installed in areas
highly susceptible to lightning strikes. Figure 17 shows the 5-screw terminal block used when the lightning
protection option is ordered.
Barriers can be installed per manufacturer’s instructions for transmitters to be used in intrinsically safe
applications.
Wiring connections
The procedure in Table 14 shows the steps for connecting loop power to the transmitter. For loop wiring
and external wiring diagrams, refer to the installation drawings presented in Section 13. Detailed drawings
are provided for transmitter installation in non-intrinsically safe areas and for intrinsically safe loops in
hazardous area locations.
ATTENTION
All wiring must comply with local codes, regulations, and ordinances.
If you will be using the transmitter in a hazardous area, be sure to review the hazardous
location reference data included in Appendix D of this manual before wiring and operating the
transmitter.

Approval body requirements
If your transmitter was ordered with Table III option 3N for self-declared approval per 94/9/EC (ATEX4),
you must use a power supply that includes a voltage limiting device that will keep the voltage to the
transmitter from exceeding 42 Vdc. You can achieve this by using a battery as the supply or one of these
voltage limiting means.
• Double wound mains transformer per BS 3535 or equivalent.
• An adequately rated zener diode whose voltage is not significantly higher than the rated voltage.
• An adequately rated semiconductor voltage regulator.
6/05
35
Lightning protection
When your transmitter is equipped with optional lightning protection (option LP), you must connect a wire
from the transmitter to ground as shown in Figure 17 to make the protection effective. We recommend that
you use a size 8 AWG (American Wire Gage) or (8.37mm2) bare or green covered wire.

About this section
This section tells you how to establish communications with the ST 3000 and make initial checks of the
transmitter’s settings and configuration using a HART hand-held communicator. This section includes
these topics:
•
Verifying that the HART communicator contains the proper software version for communicating the
ST 3000 transmitter.
•
Making proper connections of the HART communicator to the ST 3000 transmitter.
•
Begin communications between the transmitter and the communicator.
•
Make initial checks to the transmitter, such as checking factory set configuration, verify write protect
option and failsafe direction, and change if necessary.

Transmitter write protection option
The ST 3000 transmitters have a transmitter security option, also known as a “write protect option,” which
is jumper-selectable. You can position the jumper, located on the transmitter’s printed wiring assembly
(PWA), to allow read and write access or read only access to the transmitter’s configuration database.
When the jumper is in the read only position, you can only read/view the transmitter’s configuration and
calibration data.
The factory-default jumper position is for read and write access. There is no need to check jumper position
unless you want to change it. If you do want to change the jumper position, refer to the procedure in
Section 8. Figure 19 below shows the location of the write protect jumper on the PWA.

About configuration
Each ST 3000 transmitter includes a configuration database that defines its particular operating
characteristics. You can use a communicator to change selected parameters within a given transmitter’s
database to alter its operating characteristics. This process of viewing and/or changing database parameters
is called “configuration.”

Figure 21 Summary of Configuration Process
Transmitter configuration can be accomplished both on-line— with the transmitter powered up and
connected to the communicator, or off-line— where you enter the configuration in the communicator and
then store it in memory for later downloading to the transmitter
Communicator and ST 3000 transmitter memories
As shown in Figure 22, both the communicator and the ST 3000 transmitter have working memories. They
serve as temporary storage areas for data exchanged between them during communications.
The transmitter also has a nonvolatile memory that is the permanent storage area for a backup copy of all
the data held in the working memory. Nonvolatile memory retains its data even if the transmitter loses
power.
The communicator has a second temporary storage area called the off-line memory (memory module or
data pack). It serves as a permanent storage area for a saved configuration database. The memory module
or data pack supports the communicator’s SEND function to restore a saved configuration database to a
transmitter. Figure 22 shows the working relationship between communicator and transmitter memories
during communications.

Copying transmitter configuration into nonvolatile memory
When setting up or configuring a ST 3000, whether you are changing one value or a configuration
database, all configuration data must be copied into the transmitter’s non-volatile memory to ensure the
security of the data.
Normally, thirty seconds after a value is changed, the transmitter automatically copies it from the
transmitter’s working memory into nonvolatile memory. But, if you change a value and power is
interrupted to the transmitter before the change is copied to nonvolatile memory, you will lose the data in
the working memory and it will not be saved in nonvolatile memory.
Therefore, when data is sent (downloaded) to the transmitter, be sure power to the transmitter is not
interrupted before it can be copied to nonvolatile memory.

About square root output
For differential pressure transmitters measuring the pressure drop across a primary element, the flow rate is
directly proportional to the square root of the differential or pressure drop. The ST 3000 transmitter’s
output is automatically converted to equal percent of flow when its output conformity is configured as
square root.
You can use these formulas to manually calculate the percent of flow for comparison purposes.
(Note: This formula assumes that LRV = 0.)
∆P
Span • 100 = %P
Where,
Therefore,
∆P
= Differential pressure input in engineering units
Span
= Transmitter’s measurement span (URV – LRV)
%P
= Pressure input in percent of span
%P
100 • 100 = % Flow
And, you can use this formula to determine the corresponding current output in milliamperes direct current.
(% Flow • 16 mA) + 4 mA = mA dc Output
60
6/05
6— Configuration - Pressure transfer function— Selecting Output Conformity
EXAMPLE:
If you have a differential pressure transmitter with a range of 0 to 100 inches of water
with an input of 49 inches of water, substituting into the previous formulas yields:
49
100 • 100 = 49%
49%
100 • 100 = 70% Flow, and
70% • 16 + 4 = 15.2 mA dc Output
Square root dropout
To avoid unstable output at readings near zero, the ST 3000 transmitter automatically drops square root
conformity and changes to linear conformity for low differential pressure readings. As shown in Figure 26,
the point is near 0.5% of input for ST 3000 transmitters.

6— Configuration - PV damping— Adjusting Damping Time
PV damping— Adjusting Damping Time
You can adjust the damping time to reduce the output noise. We suggest that you set the damping to the
smallest value that the system can accept.
ATTENTION
The electrical noise effect on the output signal is partially related to the turndown ratio of the
transmitter. As the turndown ratio increases, the peak-to-peak noise on the output signal
increases. You can use this formula to find the turndown ratio using the range information for
your transmitter.
Upper Range Limit
Turndown Ratio = (Upper Range Value – Lower Range Value)
EXAMPLE:
The turndown ratio for a 400 inH2O transmitter with a range of 0 to 50 inH2O would be:
400

Turndown Ratio = (50 – 0) = 1 or 8:1

Poll addr— Selecting Poll Address
You can select the poll address for the transmitter that determines certain communications characteristics.
HART communications protocol provides for communications to multiple HART devices connected on the
same loop (multidrop mode). In a multidrop mode, each device in the loop must be given a unique address.
A device with a poll address of 1 through 15 is identified as being in multidrop mode. Communication
between the communicator and the devices takes place digitally, with the analog output remaining constant
(fixed at 4 mA average).
A device with a poll address of 0 (zero) will provide a 4 to 20 mA analog output as well as receive
requests and respond to commands from the HART communicator.

Start-up Tasks
About start-up
Once you have installed and configured a transmitter, you are ready to start up the process loop. Start-up
usually includes
• Applying process pressure to the transmitter,
• Checking zero input, and
• Reading input and output.
You can also run an optional output check to “wring out” an analog loop prior to start-up.
Procedure reference
The actual steps in a start-up procedure will vary based on the type of transmitter and the measurement
application. In general, you use the communicator to check the transmitter’s input and output under static
process conditions, and make adjustments as required, before putting the transmitter into full operation with
the running process.
Choose the applicable procedure to reference in this section from Table 27 based on your type of
transmitter and the measurement application. The reference procedure will give you some idea of the
typical tasks associated with starting up a transmitter in a given application.

Running Analog Output
Background
You can put the transmitter into a constant-current source mode to check out other instruments in the loop
such as recorders, controllers, and positioners. Using the communicator, you can tell the transmitter to
change its output to any value between 4 mA (1V or 0%) and 20 mA (5V or 100%) and maintain that
output. This makes it easy to verify loop operation through the accurate simulation of transmitter output
signals before bringing the loop on line. Note that the constant-current source mode is also referred to as
the output mode.
ATTENTION
The transmitter does not measure the input or update the output while it is in the constantcurrent source mode.
Procedure
The procedure in Table 28 outlines the steps for using a transmitter in the constant current source mode.
Table 28 Using Transmitter in Constant-Current Source (Output) Mode
Step

Changing Default Failsafe Direction and Write Protect Jumpers
Default failsafe direction
Transmitters are shipped with a default failsafe direction of upscale. This means that the transmitter’s
output will be driven upscale (maximum output) when the transmitter detects a critical status.
The upscale failsafe action will drive an analog transmitter’s output to 20.8 mA or a downscale action will
drive its output to 3.8 mA.
The HART communicator parameter PV AO Alrm Typ identifies the failsafe direction of the transmitter.
The parameter indicates failsafe action as either Hi (upscale) or Lo (downscale).
Write protect option
Transmitters are shipped with a default jumper position for read and write access. This means that the
transmitter’s configuration database can be overwritten.
Procedure
The procedure in Table 37 outlines the steps for cutting the failsafe jumper and/or repositioning the write
protect jumper on the transmitter’s Printed Wiring Assembly (PWA). Figure 36 shows the location of the
jumpers on the PWA of ST 3000 Release 300 transmitters.
ESD HAZARD
The nature of the integrated circuitry used in the transmitter’s PWA makes it susceptible to
damage by stray static discharges when it is removed from the transmitter. Follow these tips to
minimize chances of static electricity damage when handling the PWA.
• Never touch terminals, connectors, component leads, or circuits when handling the PWA.
• When removing or installing the PWA, hold it by its edges or mounting bracket only. If you
must touch the PWA circuits, be sure you are grounded by staying in contact with a
grounded surface or wearing a grounded wrist strap.
• As soon as the PWA is removed from the transmitter, put it in an electrically conductive bag
or wrap it in aluminum foil to protect it.

Introduction
About this section
This section provides information about preventive maintenance routines and replacing damaged parts. The
topics covered in this section are:
Preventive maintenance of the meter body barrier diaphragms and process piping to the transmitter.
Replacement of damaged parts such as the transmitter PWA and meter body.
Preventive Maintenance
Maintenance routines and schedules
The ST 3000 transmitter itself does not require any specific maintenance routine at regularly scheduled
intervals. However, you should consider carrying out these typical inspection and maintenance routines on
a schedule that is dictated by the characteristics of the process medium being measured and whether blowdown facilities or purge systems are being used.
Check piping for leaks.
Clear the piping of sediment or other foreign matter.
Clean the transmitter’s pressure chambers including the barrier diaphragms.
Inspecting and Cleaning Barrier Diaphragms
Depending on the characteristics of the process medium being measured, sediment or other foreign
particles may collect in the process head cavity/chamber and cause faulty measurement. In addition, the
barrier diaphragm or diaphragms in the transmitter’s meter body may become coated with a residue from
the process medium. The latter is also true for external diaphragms on flange mount and remote seal type
transmitters.
In most cases, you can readily remove the process head or heads from the transmitter’s meter body to clean
the process head cavity and inspect the barrier diaphragm or diaphragms. For flange mount and remote seal
diaphragms, you may only need to run a purge line in the tank to rinse off the face of the diaphragm.
Procedure
The procedure in Table 41 outlines the general steps for inspecting and cleaning barrier diaphragms. You
may have to modify the steps to meet your particular process or transmitter model requirements. Figure 38
shows an exploded view of a DP transmitter’s meter body for reference.

heads and bolts. See Figure 38.
3
Remove O-ring and clean interior of process head using soft bristle brush and suitable solvent.
4
Inspect barrier diaphragm for any signs of deterioration or corrosion. Look for possible residue
and clean if necessary.
If diaphragm is dented, has distorted convolutions or radial wrinkles, performance may be
affected. Contact TAC for assistance.
5
Replace O-ring.
ATTENTION
• We recommend that you install a new O-ring whenever a process head is removed for
cleaning.
• The process head for a GP or an AP transmitter with single-head design has two O-ring
grooves. A large one which is 2 inches (50.8 mm) in diameter and a small one which is 1.3
inches (33 mm) in diameter as shown in the following illustration. On high pressure model
STG180, GP transmitters, use the small O-ring in the smaller/inner groove. On other
models of GP and AP transmitters, use a large O-ring in the larger/outer groove. Never use
both O-rings together.

10— Calibration
Introduction
About this section
This section provides information about calibrating the transmitter’s analog output and measurement range.
It also covers the procedure for resetting calibration to default values as a quick alternative to measurement
range calibration.
How to calibrate the transmitter’s analog output circuit using the communicator
How to perform a two-point calibration of the transmitter
How to perform a corrects reset to return the transmitter calibration to its default values.
Overview
About calibration
The ST 3000 Smart Transmitter does not require recalibration at periodic intervals to maintain accuracy. If
a recalibration is required, we recommend that you do a bench calibration with the transmitter removed
from the process and located in a controlled environment to get the best accuracy.
Before you recalibrate the transmitter’s measurement range, you must calibrate the transmitter’s analog
output signal. See Table 44 for procedure.
You can also use the communicator to reset the calibration data to default values, if they are corrupted,
until the transmitter can be recalibrated. See Table 46 in this section for details.
ATTENTION
Equipment Required
ATTENTION
Depending upon the calibration you choose, you may need any of the following test equipment
to accurately calibrate the transmitter:
• Digital voltmeter or milliammeter with 0.02% accuracy or better
• HART hand-held communicator
• Calibration-standard pressure source with a 0.02% accuracy
• 250 ohm resistor with 0.01% accuracy or better.
6/05
107
10— Calibration - Calibrating Analog Output Signal
Calibrating Analog Output Signal
You can calibrate the transmitter’s analog output circuit at its 0 and 100% levels by using the transmitter in
its constant-current source mode. It is not necessary to remove the transmitter from service.
The procedure in Table 45 shows the steps for calibrating the output signal for a transmitter in the analog
mode.
ATTENTION
You can calculate milliamperes of current from a voltage measurement by using the following
equation:
voltage
dc milliamps = 1000 x resistance
Table 45 Calibrating Output Signal for Transmitter in Analog Mode
Step
1
Action
Connect communicator across loop wiring and turn it on.
See Figure 27 in Section 7 for sample test equipment hookup.
ATTENTION
Be sure the accuracy of the resistor is 0.01% or better for current measurements made by
voltage drop.

Calibrating Range
The ST 3000 Smart Transmitter has two-point calibration. This means when you calibrate two points in the
range, all the points in that range adjust to that calibration.
The procedure in Table 46 shows the steps for calibrating a differential pressure (DP) type transmitter to a
range of 0 to 200 inH2O for example purposes. This procedure assumes that the transmitter is removed
from the process and located in a controlled environment.
ATTENTION
You must have a precision pressure source with an accuracy of 0.02% or better to do a range
calibration. Note that we factory calibrate ST 3000 Smart Transmitters with inches of water
ranges using inches of water pressure referenced to a temperature of 39.2˚F (4˚C).
Table 46 Calibrating Measurement Range
Step

Resetting Calibration
Background
Every ST 3000 transmitter is factory-characterized. The characterization process calculates a mathematical
model of the performance of the transmitter’s sensors and stores that data in the transmitter’s memory.
Small residual errors result from the sensor data acquisition and modeling process. These errors can be
eliminated through calibration, using either a zero offset or a span correction.
A Corrects Reset returns the zero and span calibration factors to their default values. The transmitter
calculates its output based on the characterization equation alone, without any compensation for the
residual errors.
A typical zero offset correction is less than 0.1 inches of water (based on a 400 inH2O range) and a typical
span correction is less than 0.2% regardless of the range of calibration (down to the point where
specification turndown begins). Typical performance of a 400 inH2O transmitter with Corrects Reset can
be expressed as:
Accuracy = 0.2% + (0.1”/span”) • 100%
By calibrating the zero, the typical performance will be 0.2% or better.
For transmitter ranges other than 400”, the initial zero offset will be scaled by the ratio of the Upper
Range Limit to 400. For example, for a 100 psi transmitter, the initial zero offset can be expressed by:
0.1” • 2768/400 = 0.7” or 0.025 psi.
Please note that these are typical values, not hard specifications.

Introduction
About this section
This section identifies diagnostic messages that may appear in the communicator and describes what they
mean. An interpretation of diagnostic messages is given and suggestions of the possible cause and
corrective action for each message. Procedures are provided for running a status check.
A summary of the different diagnostic message categories that can be displayed by the communicator.
A description of the diagnostic messages and a recommended action to correct the condition or fault.
Troubleshooting Overview
Diagnostics
The communicator and ST 3000 transmitter are constantly running internal diagnostics to monitor the
functions and status of the control loop and their communications link.
When a diagnostic failure is detected, a corresponding message is generated for the communicator display.
Troubleshooting tool
Your primary troubleshooting tool is using the communicator for status messages and then interpreting the
diagnostic messages. You should also use the communicator to verify the transmitter’s configuration data
and check to be sure that your process is operating correctly.
To access transmitter diagnostics
You access the transmitter diagnostics starting at the “Online” menu of the communicator.
You then select:
Device setup
Diag/Service
Device status
The Device status menu appears.

Diagnostic Messages
Summary
The diagnostic messages can be grouped into one of these three categories:
Critical Failures
Non-Critical Failures
Communication Errors
A description of the messages in each category is given in the following paragraphs.
Critical failures
Table 48 summarizes the critical communicator status message displays. A critical failure drives the
transmitter’s output to its failsafe direction—upscale or downscale.
Table 48 Summary of Diagnostic Messages for Critical Failures

11— Troubleshooting - Clearing Critical Status
Clearing Critical Status
After a critical failure has been diagnosed and corrected the critical status must be cleared from the
transmitter. This can be done by performing a master reset using the communicator.
A master reset causes a hardware reset of the transmitter, which actually is the same as cycling the power to
the transmitter.
Table 52 outlines the steps for resetting the transmitter.

Appendix A— Smart Meter Reference - Introduction
Smart meter option
Depending upon your transmitter model, you can equip the ST 3000 transmitter with the Smart Meter
option (option SM). This new integral smart meter is designed for ST 3000 Release 300 Transmitters and
provides functionality not available with other smart meter designs.
The smart meter provides an LCD local interface that displays both analog and digital indications of the
transmitter output and can be configured to display pressure in user-selected engineering units.
There are three meter option types:

17-Segment Bargraph
Gives a gross indication of the transmitter’s PV output from 0 to 100%.
Digital Readout
Gives an indication of the transmitter’s PV output in either percent of
span or actual engineering units. The display range is ±19,990,000 and
it is automatically ranged to provide the best precision possible within
the limits of the display. A second decimal place expands the precision
of range values within ±19.99 to 1/100th of a unit.
%
Digital readout represents output in percent of span. This is the default
engineering units selection.
FLOW
Transmitter is configured for square root output conformity.
OUTPUT MODE
Transmitter is in its output mode and it is not sending a real PV signal.
CHECK STATUS
Transmitter in multidrop mode and showing a critical status or if
transmitter is in Analog mode, the transmitter has an output that is less
than –2.0% or greater than 106%.
Use the communicator to check transmitter’s status.

Meter Display at High and Low Temperature Extremes
The rated temperature limits for the local meter are listed above and are true in that no damage to the meter
will occur over these temperatures, however the readability of the LCD is affected if taken to these
temperature extremes:
• The LCD will turn black at some temperature between 80 to 90 °C (176 and 194 °F), rendering the
display unreadable. This effect is only temporary, and normally occurs at 90 °C (194 °F).
• At low temperatures, the update rate of the display is lengthened to 1.5 seconds due to the slower
response time of the display. At -20 °C (-4 °F) the display becomes unreadable due to slow response
of the LCD. This is also only temporary and normal readability will return when temperature returns
above -20 °C (-4 °F).

Appendix A— Smart Meter Reference - Setting Range Values (Local Zero and Span)
Setting Range Values (Local Zero and Span)
Local zero and span option
ST 3000 Release 300 transmitters are available with optional local zero and span adjustments. This option
is for applications that do not require a HART communicator nor digital integration with our TPS system.
About local adjustments
You must apply equivalent zero and span pressures to make the local zero and span adjustments. This is
similar to LRV correct and URV set using the HART communicator. We recommend that you calibrate the
transmitter before setting up the meter for custom engineering units.
The procedure in Table A-4 shows the steps for setting the range values to applied pressures using local
zero and span adjustments. See Figure A-2 for typical local adjustment setup details.
ATTENTION
After making any adjustments to the smart meter, keep the transmitter powered for at least 30
seconds so that the new meter configuration is written to non-volatile memory. If power is
turned off before 30 seconds, the changes may not be saved so that when the transmitter
power is restored, the meter configuration will revert to the previous settings.
Table A-4 Setting Range Values Using Local Zero and Span Adjustments
Step
Action
1
Turn OFF transmitter power. Loosen end-cap lock and remove end-cap from terminal block
side of electronics housing.
2
Observing polarity, connect a milliammeter across positive (+) and negative (–) TEST terminals.
ATTENTION
If you have the smart meter with local zero and span adjustment option, you may use the

Action
Turn ON transmitter power and let it warm up for a few minutes. Using an accurate pressure
source, apply desired zero equivalent pressure to transmitter.
ATTENTION
For differential pressure transmitters, apply pressure to the high pressure head for positive
range values or vent both heads to atmosphere for zero. If zero is to equal a negative value,
apply the equivalent pressure to the low pressure head. For example, if zero is to equal –10
inH2O, you would apply 10 inH2O to the low pressure head and vent the high pressure head
for the zero adjustment.
5
Check that milliammeter reading is 4 mA.
• If reading is less or greater than 4 mA, Then go to Step 6.
• If reading is correct, go to Step 7.
ATTENTION
If you have the smart meter with local zero and span adjustment option, you may substitute
the smart meter readings for the milliammeter readings. For example, with zero input pressure
applied assume that the meter reads 4 inH2O instead of 0 inH2O. In this case, the meter
reading is greater than 0 (or 4 mA).
6
d)
Press and hold ZERO button on local zero and span assembly or smart meter.
ATTENTION
The smart meter readings revert to the default unit of percent (%) during this operation. If the
error code Er0 appears on the display, you are working with a model STD110 transmitter that
does not support the local zero and span adjustments.
e)
Press Decrease
button once to complete this function.
The smart meter display goes blank for a 1/2 second and then returns reading 0%.
f) Check that milliammeter reading equals 4 mA and release ZERO button.
ATTENTION
If milliammeter reading doesn’t change, be sure you are not working with a model STD110
transmitter that ignores local adjustments. The smart meter readings return to the set
engineering units after you release the ZERO button.
If zero correction is + or – 5% of upper range limit, the CHECK STATUS indicator will be
displayed. If range setting is intentional, disregard status message.
7
Using an accurate pressure source, apply pressure equivalent to desired upper range value to
transmitter.
ATTENTION
For differential pressure transmitters, apply pressure to the high pressure head and be sure
that the low pressure side is vented to atmosphere.
If the applied pressure produces an output of greater than 200%, the meter display will flash
O-L and the 200% value during this interim step.

• If reading is correct, go to Step 10.
ATTENTION
If you have the smart meter with local zero and span adjustment option, you may substitute
the smart meter readings for the milliammeter readings. For example, with URV input pressure
applied, assume that the meter reads 396 inH2O instead of 400 inH2O. In this case, the
meter reading is less than 100% (or 20 mA).

a)
Press and hold SPAN button on local zero and span assembly or smart meter.
ATTENTION

ATTENTION
If the error code Er4 appears, you are trying to set a SPAN value that is outside acceptable
limits for your transmitter. Readjust applied pressure to be within acceptable range limits and
repeat this procedure. The smart meter display goes blank for a 1/2 second and then returns
reading 100%.

Configuring Smart Meter Using Pushbuttons
The smart meter can be set to show the PV output in engineering units that are appropriate for your process
application. You can select an available engineering unit or enter a custom one including upper and lower
display limits settings for the smart meter’s digital readout using buttons on the face of the meter.
Using the Smart Meter
Follow these guidelines when configuring the smart meter:
If you initiate a command with the HART communicator at the same time a button is pressed on the smart
meter, the smart meter will respond to the command it receives last. In other words, the last command
wins.
In most cases, you can press and release a button for one-shot operation, or press and hold a button for
continuous, 1/2 second, repetitive operation.
Active setup field will begin to flash at one second rate if next action is not initiated within one second.
And, if no action is taken within 30 seconds, the setup function will time out and the meter will return to
its previous state.

Transmitter Output Conformity and Smart Meter Configuration
Normally when using a differential type transmitter, you can select the transmitter’s output to represent a
straight linear calculation or a square root calculation for flow measurement applications. This linear or
square root output parameter selection is called output conformity or output form. (See Section 6 for more
details on output conformity.)
When configuring the smart meter to display the transmitter output measurement, there are certain rules to
keep in mind which are dependent on the output conformity selection. These rules are described in the
following paragraphs.
The output conformity setting of the transmitter restricts the engineering units you can select for the smart
meter display.
When the transmitter is configured for an output conformity of LINEAR, you can select only pressure
type engineering units. (See Table A-5.)
When the transmitter is configured for an output conformity of SQUARE ROOT, you can select only
flow type engineering units GPM and GPH.
The percent and custom engineering units can be selected regardless of output conformity configuration.

Additionally, the output conformity setting restricts the setting of the lower and upper display limits to
represent transmitter’s 0 to 100% output.
If you select pressure type engineering units, you cannot set the lower or upper display limits. These
values are automatically set when you select the engineering units.
You can set only the upper display limit when the transmitter is configured for SQUARE ROOT output
conformity. The lower display limit is fixed at zero (0) for a transmitter in square root mode and
cannot be changed.
You can set both the lower and upper display limits when you have selected custom engineering units
(EUF) and the transmitter output conformity is set to LINEAR.
When setting the lower and upper display limits, if you let either the lower or upper display limit setting
time out (after thirty seconds), the meter will discard the newly set values and will revert to its previous
settings. The meter forces you to set both limits by automatically initiating the next limit setting, either
lower or upper, depending upon which limit you set first.
If you change the transmitter’s output conformity, you must reconfigure the smart meter as outlined in
Tables A-6, A-7 and A-8 or Table A-9. See also “Meter/transmitter interaction” in this appendix.
Selecting Engineering Units
The procedure in Table A-6 outlines the steps for selecting the desired engineering units for a smart meter
using its local adjustments on the face of the meter. You will be selecting the unit of measurement that
you want the smart meter to indicate during normal operation.

To set the lower and upper display limit values for the meter display perform the procedures in Tables A-7
and A-8. Also note that in each procedure you must:
First set the magnitude range for each display value. This enables the multiplier (K) on the display for
indicating larger ranges (greater than 19999 and shifts the decimal point of the digital display left or
right depending on the precision you want to show for that value).
Next set the display value. This procedure sets the display limit of the meter to represent minimum and
maximum transmitter output (0% and 100 % output).
Note: Magnitude range and display values are set for both upper and lower (if applicable) display limits.
During normal operation the display range of the meter digital readout is ±19,990,000 and is automatically
ranged to provide the best precision possible for the digits available up to 1/100th of a unit.
ATTENTION
Please read through the entire procedure before beginning.

Setting Lower Display Values
The procedure in Table A-7 outlines the steps for setting the lower display limit to represent the 0 percent
(LRV) output of the transmitter.
ATTENTION
For example purposes, the procedures in Tables A-7 and A-8 assume that the lower value is
to be set at 0 and the upper value is to be set at 19,990,000 for a CUSTOM unit in a
transmitter with a LINEAR output, and the transmitter’s present output is exactly 50 percent.

The output conformity setting of the transmitter restricts the engineering units you can select for the
smart meter display.
When the transmitter is configured for an output conformity of LINEAR, you can select only pressure
type engineering units. (See Table A-5.)
When the transmitter is configured for an output conformity of SQUARE ROOT, you can select only
flow type engineering units GPM and GPH.
The percent (%) and custom engineering units can be selected regardless of output conformity
configuration.
2. Additionally, the output conformity setting restricts the setting of the lower and upper display limits to
represent transmitter’s 0 to 100% output. The table below shows the restrictions on setting display
values for given engineering units and output conformity selections.

Appendix C – Freeze Protection of Transmitters - Possible Solutions/Methods
Appendix C – Freeze Protection of Transmitters
Problem
When water is present in the process fluid and ambient temperatures can fall below the freezing point
(32°F/0°C), pressure transmitters and their piping require freeze protection. Transmitters may also require
continuous heating, if the process fluid is tar, wax, or other medium which will solidify at normal ambient.
However, uncontrolled steam or electric heating, in addition to wasting energy, can cause errors and
accidentally destroy the transmitter.
Possible Solutions/Methods
Solution
These two basic solutions are possible:
Eliminate the need for heating the transmitter by keeping the freezable process fluid out of direct contact
with transmitter.
Control the steam or electric heat to prevent overheating on warm days while protecting against freeze-ups
under the coldest conditions.
The following paragraphs in this appendix describe a number of methods for implementing both solutions.
Sealing liquid method
The simplest and least costly method is to use a sealing liquid in the transmitter meter body and its impulse
piping to the process. The small contact (interface) area between the sealing liquid and the process fluid
reduces the mixing of the two fluids.
You should select a sealing liquid that has a greater specific gravity than the process fluid to inhibit mixing.
It also must have freezing and boiling temperatures compatible with the range of temperatures existing at
the site, including the heated interface.
WARNING
The user must verify the compatibility of any sealing liquid with their process fluid.
A reliable sealing liquid is a 50/50 percent (by volume) solution of ethylene-glycol and water. This solution
has a specific gravity of 1.070 at 60°F (15°C), a freezing temperature of –34°F (–36°C), and a boiling
temperature of +225°F (+106°C) at atmospheric pressure. Conventional antifreeze liquids for automobile
coolant systems such as Prestone and
Zerex are solutions of ethylene-glycol with some rust inhibitors and possibly leak sealants added; they may
be used in place of pure ethylene-glycol.
Another sealing liquid, used in many chemical plants, is dibutylphalate an oily-type liquid with a specific
gravity of 1.045 at 70°F (21°C). It has a boiling point 645°F (340°C) and does not freeze so it can be used
down to about –20°F (–30°C).
Figures C-1 and C-2 show typical piping installations for this method. The process fluid must be heated
above its freezing point. This is frequently done by lagging in (insulating) the connecting nipple, shut-off
valve and “T” connector with the process piping. Where the process piping itself requires heating, a steam
or electric trace is run around their components with consideration given to the boiling point of the sealing
liquid.

Purging
Purging air or water purges are commonly used to prevent viscous materials from clogging the impulse
lines to pressure, level, or flow transmitters. The bubbler system, using a constant-air flow regulator, is
particularly common on open tank liquid level applications. No heating of impulse lines or transmitter is
required, but normal precautions are required to keep water out of the air supply system.
Gas applications
We must not overlook the possibility of condensate freezing in impulse lines to transmitters measuring gas
flow or pressure. Although these components could be heated similar to water and steam applications, the
simplest and best approach is to install transmitters so that they are self draining. This means that the
impulse lines are connected to the lowest point in the transmitter meter body and the piping is sloped
downward at least one inch per foot. (Side-connected transmitters with vent-drains at a lower point in the
meter body must be regularly checked to assure condensate removal.) If the transmitter is located below the
process taps (not recommended), piping must still run downward from the transmitter to the drain point and
then up to the process as shown in Figure C-3. Steam or electric heating of the drain point will prevent
pipe rupture due to freezing.
Transmitter
Figure C-3 Piping Installation for Gas Flow.
Mechanical (diaphragm) seals
Diaphragm seals on the impulse lines provide the most expensive, yet broadest application of all the
methods. Similar in principle to the liquid seals, diaphragm seals eliminate the possibility of seal liquid
carry-over into the process fluid. This eliminates the need for periodic maintenance checks to assure full
and equal liquid seal legs. Welded diaphragm seals with special fills permit temperatures from –34° to
600°F (–36° to 315°C) at the process interface which can therefore be steam or electrically heated to assure
viscosity of tars and similar high-freezing point fluids under the coldest conditions.
You must be careful to specify large enough diaphragms to accommodate expansion and contraction of the
fill fluid under varying temperatures without overextending the diaphragm into its stiff area. In general,
conventional diaphragm seals are satisfactory for pressure ranges above approximately 75 psig with special
large diameter elements required for low pressure or differential pressure measurements.
You can lag (insulate) impulse lines and diaphragm seals with the process piping, but this practice is only
common with liquid level applications involving highly viscous materials unsuitable for 1/2-inch impulse
6/05
171
lines. Use a tank-mounted flanged seal in such installations. Otherwise, it is more desirable to keep the
capillary lengths short, the transmitter accessible for maintenance, and (for flow applications) the normal 3valve manifold assembly close to the transmitter for normal service checks. Thus, the impulse lines,
valving and diaphragm seals with 1/2-inch connections would be electrically or steam traced, with high
temperature steam permitted without damage to the transmitter. Figures C-4 and C-5 show typical piping
layouts.

manifold, and upper flanges

required, also heated by

Electric heating
Most transmitters will withstand higher temperatures at their process interfaces (bodies) than at their
electronics. Normally, it is impractical to heat transmitter bodies above 225 to 250°F (107 to 121°C)
without radiant and conducted heat exceeding the rating at the electronics (normally 200°F/93°C).
Prefabricated insulated enclosures with integral heating coils and thermostats set at 200°F (93°C) can
assure viscosity of fluids which freeze below 180°F (82°C) while assuring safe transmitter operation. For
water or similar lower-temperature mediums, the control can be set at 50°F (10°C) to save energy and call
for heat only when temperature and wind conditions require.
Systems can be engineered for uncontrolled, continuous electric heating to prevent water freezing at 0°F (–
18°C) and 20 mph wind velocity, while not exceeding 225°F (107°C) at the transmitter body at 90°F
(32°C) ambient and zero wind velocity. The operating costs in energy for these systems usually exceed the
high initial cost of the thermostat systems. Never attempt to maintain freeze points above 100°F (38°C)
without thermostat controls since the Btu required to prevent freezing will normally exceed the body
temperature rating under opposite extremes.
Although systems are available with hollow bolts replacing the normal transmitter body bolts and
containing electrical heating elements and thermostats, certain precautions are required with such
arrangements. Some transmitter meter body bolts are too small to accept the available thermostats. Also
thermostat settings should not approach the body temperature limit because the heat gradient across the
meter body can be such that limits are exceeded adjacent to the heating elements even when the thermostat
setting is lower.
Electrical heating systems are available in explosionproof ratings for Class I, Group D, Division I and II
installations.
The possibility of electric supply failure must be considered. For this reason, we recommend using alarm
devices with manual acknowledgment and reset. Figures C-6 and C-7 show typical piping installations.

Steam heating
Steam heating is perhaps the most common, yet potentially the most damaging method of protecting
transmitters from freeze-ups. Since steam is generated for use in the overall process operation, it is
considered an available by-product. The most important point to remember when steam heating transmitter
meter bodies is the temperature of the steam that will be used and its pressure. We recommend that you
review the next paragraph Superheated steam considerations to get a better understanding of the
temperature problem with steam heating. In brief, do not assume that 30 psig steam is 274°F (134°C) and
cannot damage a transmitter rated for 250°F (121°C). With steam heating, as with electrical, you should
use insulated transmitter body housing, impulse piping and valves.
It is common practice to use conventional steam traps on all steam heating systems. They permit live,
superheated steam to enter the heating coils and piping down to the trap. You should also use conventional
steam traps with lower pressure desuperheated steam which cannot overheat the transmitter under warmday conditions. If the heating pipes are not carefully installed to eliminate low spots and trapped condensate
in the piping, they could freeze at low temperatures.
All steam traps require a periodic maintenance program. Dirt, scale, and water softeners will cause traps to
stick or jam which result in their either blowing steam continuously or not blowing steam, allowing
condensate freeze-up in cold weather. When steam traps are used for cold-weather freeze protection of
water lines, a thermostat controlled steam supply valve, which will shut off the steam at ambient
temperatures higher than 50°F (10°C), will save steam and prevent overheating.
A more general solution is offered by a specialized type of trap which throttles condensate flow based on
its temperature. This backs up hot water in the radiator within the insulated transmitter enclosure, assuring
temperatures no higher than the saturated steam at the reduced pressure. Models are available to set the
condensate temperature from about 70° to 200°F (21° to 93°C). They must be located within 6 to 12 inches
6/05
174
(15 to 30 cm) of the transmitter body and, like all steam traps, they also require periodic maintenance. The
engineering of this type system is more complex than electric systems since the amount of heat loss
upstream of the CTV valve under varying conditions will determine the location of the steam/water
interface. It could occur within the heater coil or further up the steam line, thus affecting the heating
efficiency within the insulated enclosure. Therefore, steam control of materials which freeze or become too
viscous above 100°F (38°C) should probably not be attempted without some experimenting with the
specific piping layout used.
Uncontrolled steam heating, even with the best pressure regulation and desuperheating of steam, should not
be used to maintain transmitter temperatures above 100°F (38°C), since this type of fixed Btu input must
either over or under-heat under normal ambient swings.
As with electric heating, there are many types of commercial steam heating units available such as radiant
heaters, hollow meter body studs or just tubing lagged to the impulse piping and transmitter body. The
same precaution applies to the use of hollow studs as on the electrical versions.

the various freeze protection systems.

Superheated steam considerations
We must remember that the temperature of steam is 212°F (100°C) only at the normal atmospheric pressure
of about 14.7 pounds per square inch absolute (psia). If the pressure of steam is increased above 14.7 psia,
the temperature of the steam is also increased. For example, if we have steam at 30 pounds per square inch
gage (psig), the steam temperature is 274°F (134°C).
On industrial flow and pressure measurement applications, we may be required to use steam to heat the
impulse piping to the flow or pressure transmitter, as well as the transmitter itself. For these applications,
we must verify the temperature of the heating steam used. As an example, assume that steam at 100 psig
saturated (338°F/170°C) is to be reduced to 30 psig pressure for the heating system. Too frequently, it is
assumed that this pressure reduction will result in steam at 274°F (134°C), the temperature of saturated
steam at 30 psig. Wrong! A reduction of the steam pressure will not appreciably decrease the initial steam
temperature.
In our example, we were talking about saturated steam in the main header from the boiler. But modern
industrial boilers cannot afford to let waste heat go up the stack. After reaching the boiling point in the
drum, the steam flows through a series of pipes in the second pass of the flue gas exit, extracting additional
heat energy and being raised to a temperature higher than the saturation temperature at the same pressure.
This is superheat and, depending on boiler design, it may amount to 50 to 300°F (10 to 149°C) above the
saturated steam temperature. It also permits packing more heat energy in a given size pipe for transmission
from the process. Thus, in the typical application, the problem of steam heating is compounded by the
additional superheat in the main header.
Specifically, when steam is reduced in pressure, it retains about the same latent heat or the same
Btu’s/pound at the reduced pressure. Therefore, in our example, steam at 100 psig and 338°F (170°C) when
reduced to 30 psig steam will have a temperature of 306°F (152°C) or a loss of only 32°F (18°C).
This steam temperature can only be reduced by using a desuperheater. This device mixes cold water with
the superheated steam to reduce its temperature by removing Btu’s per pound of water (steam). It is also
possible to use temperature controlled steam traps, which actually allow the steam to condense to water and
therefore reduce its temperature to a pre-set value.
Table C-2 lists the various values of steam pressure, saturated steam temperatures at these pressures,
degrees of superheat added to the saturated steam and finally the actual temperature of each when it is
reduced to 30 psig steam.

Appendix D —Hazardous Area Classifications
Introduction
Reference information
Information is provided to clarify the Hazardous Location installation requirements in North America and
internationally. An explanation of the applicable enclosure classification systems is also provided.
North American Hazardous Location Standards
NEC and CEC electrical codes
Installation of electrical apparatus within hazardous (classified) locations of the United States is conducted
under the provisions of the National Electrical Code (NEC), ANSI/NFPA 70, Article 500, and within
Canada under the provisions of the Canadian Electrical Code (CEC) C22.1, Part 1, Section 18.
Classes
Hazardous (classified) locations, in both the United States and Canada, are categorized into one of three
classes:
Class I - Presence of flammable gases or vapors may be present in quantities sufficient to produce
explosive or ignitable mixtures
Class II - Presence of combustible dusts, powders or grains
Class III - Presence of easily ignitable fibers or flyings
Divisions
The classes listed above are further categorized based upon the level of risk present:
Division 1 -
Locations in which hazardous concentrations of flammable gases or vapors - or combustible
dust in suspension – are continuously, intermittently or periodically present under normal
operating conditions.
Division 2 -
Locations in which flammable gases or vapors are present, but normally confined within
closed containers or systems from which they can escape only under abnormal or fault
conditions. Combustible dusts are not normally in suspension nor likely to be thrown into
suspension.
Examples
Given the criteria above, the following examples are made:
Class III, Division 1 - A class III, Division 1 location is a location in which easily ignitable fibers or
material processing combustible flyings are handled, manufactured or used.
Class III, Division 2 - A Class III, Division 2 location is a location in which easily ignitable fibers are
stored or handled.

Appendix D —Hazardous Area Classifications - North American Hazardous Location Standards
Group classifications
Flammable gases, vapors and ignitable dusts, fibers and flyings are classified into groups according to the
energy required to ignite the most easily-ignitable mixture within air. Group classifications are as follows:
Class I Group Classifications
Group A - Atmospheres containing acetylene.
Group B - Atmospheres containing hydrogen, fuel and combustible process gases
containing more than 30 percent hydrogen by volume, or gases or vapors
of equivalent hazard.
Group C - Atmospheres such as ethyl ether, ethylene, or gasses or vapors of
equivalent hazard.
Group D - Atmospheres such as acetone, ammonia, benzene, butane, cyclopropane,
ethanol, gasoline, hexane, methanol, methane, natural gas, naphtha,
propane or gases or vapors of equivalent hazard.
Class II Group Classifications
Group E - Atmospheres containing combustible metal dusts including aluminum,
magnesium, and their commercial alloys, and other metals of similarly
hazardous characteristics.
Group F - Atmospheres containing combustible carbonaceous dusts including carbon
black, charcoal, coal or other dusts that have been sensitized by other
materials so that they present an explosion hazard.
Group G - Atmospheres containing combustible dusts not included in Group E or F,
including flour, wood, grain, and other dusts of similarly hazardous
characteristics.

Temperature classification
Equipment intended for installation directly within the hazardous (classified) location must also be
classified for the maximum surface temperature that can be generated under normal or fault conditions as
referenced to either 40 °C or the maximum operating ambient of the equipment (whichever is greater). The
maximum surface temperature must be less than the minimum autoignition temperature of the hazardous
atmosphere present. The temperature shall be indicated in identification numbers as listed in Table D-1.

current is the maximum through any combination of terminals of a multiple channel
configuration.

*CSA does not recognize these parameters at this time
Entity concept
Under entity requirements, the concept allows interconnection of intrinsically safe apparatus to associated
apparatus, not specifically examined in such combination. The criteria for interconnection is that the
voltage (Vmax) and current (Imax), which intrinsically safe apparatus can receive and remain intrinsically
safe, considering faults, must be equal to or greater than the voltage (Voc or Vt) and current (Isc or It)
levels which can be delivered by the associated apparatus, considering faults and applicable factors. In
addition, the maximum unprotected capacitance (Ci) and inductance (Li) of the intrinsically safe apparatus,
including interconnecting wiring, must be less than or equal to the capacitance (Ca) and inductance (La)
which can be safely connected to the associated apparatus. If these criteria are met, then the combination
may be connected and remain intrinsically safe. Both FMRC and CSA define the entity parameters as
listed in Tables D-2, D-3 and D-4 below:

Appendix D —Hazardous Area Classifications - International Electrotechnical Commission (IEC) Classifications
International Electrotechnical Commission (IEC) Classifications
IEC Classification of hazardous locations
The IEC has established a number of recommendations applying to the construction of explosion protected
electrical apparatus identified. These recommendations are found within IEC 79-0 through 79-15 and 79-28.
For all EC countries as well as various neighboring countries (CENELEC member states), the European
Standards EN 50 014 to EN 50 020 and EN 50 039 apply for the construction of explosion protected
electrical apparatus. They were established on the basis of the IEC Recommendations, however in
comparison they are much more detailed.
Zones
Defined within IEC 7-10, Hazardous locations are categorized into three zones:
Zone 0 -
Explosive gas atmosphere is present continuously, or is present for long periods.
Zone 1 -
Explosive gas atmosphere is likely to occur in normal operation.
Zone 2 -
Explosive gas atmosphere is not likely to occur in normal operation and, if it does occur, it
will exist for a short period only.
Groups
Flammable gases, vapors and mists are classified into groups according to the energy required to ignite the
most easily ignitable mixture within air. Apparatus is grouped according to the atmospheres it may be used
within as follows:
6/05
Group IIC -
Atmospheres containing acetylene, hydrogen, fuel and combustible process gases or vapors
of equivalent hazard.
Group IIB -
Atmospheres such as ethyl ether, ethylene, or gasses or vapors of equivalent hazard.
Group IIA -
Atmospheres such as acetone, benzene, butane, cyclopropane, ethanol, gasoline, hexane,
methanol, methane, natural gas, naphtha, propane or gases or vapors of equivalent hazard.

NEMA and IEC Recognition
The NEMA (National Electrical Manufacturer’s Association) enclosure classifications are recognized in the
US. The IEC Publication 529 Classifications are recognized throughout Europe and those parts of the
world that use the IEC standards as a basis for product certifications. The following paragraphs provide a
discussion of the comparison between NEMA enclosure type numbers and IEC enclosure classification
designations.
IEC Classifications
IEC Publication 529, Classification of Degrees of Protection Provided by Enclosures, provides a system
for specifying the enclosures of electrical equipment on the basis of the degree of protection provided by
the enclosure. IEC 529 does not specify degrees of protection against mechanical damage of equipment,
risk of explosion, or conditions such as moisture (produced for example by condensation), corrosive
vapors, fungus, or vermin.
IEC Designations
Basically, the IEC designation consists of the letters IP followed by two numerals. The first characteristic
numeral indicates the degree of protection provided by the enclosure with respect to persons and solid
foreign objects entering the enclosure. The second characteristic numeral indicates the degree of protection
provided by the enclosure with respect to the harmful ingress of water.
NEMA Standards
NEMA Standards Publication 250, Enclosures for Electrical Equipment (1000 Volts Maximum), does test
for environmental conditions such as corrosion, rust, icing, oil, and coolants. For this reason, and because
the tests and evaluations for other characteristics are not identical, the IEC enclosure classification
designations cannot be exactly equated with NEMA enclosure type numbers.

Table D-4 provides an approximate conversion from NEMA enclosure type numbers to IEC enclosure
classification designations. The NEMA types meet or exceed the test requirements for the associated IEC
classifications; for this reason the Table cannot be used to convert from IEC classifications to NEMA
types.

User Manual 34-ST-25-17
Overview
Two new models have been added to the family of ST3000 Smart
Transmitters:
Gauge Pressure Model STG19L
Gauge Pressure Model STG99L.
Each of these has an Upper Range Limit (URL) of 10000 psi (690 bar),
which is significantly higher than previously available models. Also, each
of these new models has significantly higher ratings for Maximum
Working Pressure (10000 psi, or 690 bar) and Overpressure (15000 psi, or
1034 bar). The burst pressure is rated at 26000 psi (1793 bar).
Except for the higher operating range, each of these two new models
includes physical and functional features similar to those of closely
related family members (STG1xL and STG9xL). With the exceptions
noted in this addendum, all parts of User Manual 34-ST-25-17 apply to
these new models.
Because of the similarities between new and existing models, these new
devices can be used as direct replacements in circumstances that require
higher pressure capabilities.
Details of pressure ranges for these new models are specified in
“Additions and Changes to the Manual”, below.

Addendum
(to User Manual
34-ST-25-17)
Replacement Meterbody and Heads
The ST 3000 Pressure Transmitter, Models:
•
•
STD110, STD120, STD125, STD130, and STD170
STD924 and STD930 with optional Tantalum or Monel diaphragm
is now being shipped with newly designed meter body and process heads. If a
replacement meter body is needed, it should be ordered from the Model Number stated
on the meter body nameplate. This number includes the letter “S” after the model
number; for example, STD110S-xxx.
This new transmitter is functionally identical to previous models in that the working
ranges (Lower Range Limit to Upper Range Limit) and intended applications have not
changed. However, the specifications for the maximum Pressure Rating and for the
Overpressure Rating have been enhanced in all models except the draft range
transmitter. A summary of specifications is given in Table 5.
The new versions, which will continue as Models STD110, STD120, STD125,
STD130, STD170, STD924, and STD930, differ only in the physical size and form of
the meter body, process head, and associated components.
With exceptions noted in this addendum, information given in User’s Manual
34-ST-25-17 applies also to this newer design.
Installation, operation, maintenance, calibration, and troubleshooting tasks remain
virtually the same as for the previous version. Differences appear primarily in torque
specifications when replacing meter bodies, and in part numbering and parts
recognition when replacing components or assemblies.

This addendum provides details for parts replacement that span a variety of
applications of the Models STD110, STD120, STD125, STD130, STD170, STD924,
and STD930.

Addendum
(to User Manual
34-ST-25-17)
ATEX Directive 94/6/EC
The ATEX Directive 94/6/EC is a European CE Mark directive concerning products
that are designed for use in potentially explosive environments. This “New
Approach” directive is based on, and is an expansion of, European Norms (EN,
CENELEC standards).
On June 30, 2003, the ATEX (ATmospheres EXplosibles) directive will replace
directives currently in effect, and from that time, only products with the ATEX
certification and with ATEX labeling will be approved for free movement in the EU
(European Union) and EFTA (European Free Trade Association) countries. As
defined in the directive, “free movement” refers to:
−
placing a product on the market, and/or
−
placing a product into service.
The ATEX Directive 94/6/EC is a living (set of) document(s), subject to further
change and refinement, whose details are beyond the scope of this addendum.
Further information can be obtained in the Official Journal of the European
Communities No L100/1, and in related publications such as Guidelines on the
Application of Directive 94/9/EC. Both of these items are available at:
http://europa.eu.int/comm/enterprise/atex/index.htm
Products that have been previously certified under the EN and CENELEC European
Norms, and which comply fully with all standards in the New Approach directive
have, by application, received certification under ATEX Directive 94/6/EC.
The Honeywell ST3000 Smart Pressure Transmitter is now ATEX certified, and all
units manufactured currently and in the future will include labeling that includes all
markings required under the ATEX directive.
Inclusions
To ensure that all required information will be available to the user, the following
items are included with this Addendum for reference:
1.
Declaration of Conformity – ATEX CE0344 (Honeywell document number
51452504 Revision B).
2.
Certificate of Manufacturer – Ex II 3 G, EEx nA IIC ATEX CE (Honeywell
document number 51452622 Revision C).
Purpose and Content
of this Addendum
This Addendum includes information required under the ATEX Directive regarding:
1. The appearance and meaning of each certification mark (CE Mark) that appears on
the label(s) affixed to the product.
2. Instructions for installation and use of the product.
