OVERVIEW The Advanced HART Diagnostic Suite is an extension of the Rosemount 3051S

Series of Instrumentation and takes full advantage of the scalable architecture.
The 3051S SuperModule™ Platform generates the pressure measurement while
the diagnostic electronics board is mounted in the PlantWeb housing and plugs
into the top of the SuperModule. The electronics board communicates with the
SuperModule and produces standard 4 – 20 mA and HART outputs while adding
advanced diagnostic capability.

NOTE

When a new SuperModule is connected to the diagnostic electronics board for the
first time, the transmitter will be in alarm state until pressure range is specified.

The Advanced HART Diagnostics Suite is designated by the option code “DA2” in
the model number. All options can be used with DA2 except the following:

• Foundation Fieldbus protocol (Output code F)

• Wireless (Output code X)

• Quick Connect (Housing code 7J)

• Junction box (Housing code 2A, 2B, 2C, 2J)

• Remote display (Housing code 2E, 2F, 2G, 2M)

The HART Diagnostic transmitter has seven distinct diagnostic functions that can
be used separately or in conjunction with each other to detect and alert users to
conditions that were previously undetectable, or provide powerful troubleshooting
tools.

7-1

Rosemount 3051S Series

1. Statistical Process Monitoring (SPM) – SPM technology detects changes
in the process, process equipment or installation conditions of the
transmitter. This is done by modeling the process noise signature (using
the statistical values of mean, standard deviation, and coefficient of
variation) under normal conditions and then analyzing the recorded
baseline values to current values over time. If a significant change in the
current values is detected, the transmitter can generate HART alerts or
analog alarms, depending on user configuration. The condition is time
stamped and is also noted on the LCD.

The statistical values are also available as secondary variables from the
transmitter via HART. Users can trend their process noise signature,
perform their own analysis or generate their own alarms or alerts based
on the secondary variables. Trending of statistical values in an analog
system can be done with the Smart Wireless THUM Adapter or
Rosemount 333 Tri-Loop. Refer to pages 7-33 and 7-34 for more details.

2. Power Advisory Diagnostic – This diagnostic functionality detects
changes in the characteristics of the electrical loop that may jeopardize
loop integrity. This is done by characterizing the electrical loop after the
transmitter is installed and powered up in the field. If terminal voltage
deviates outside of user configured limits, the transmitter can generate
HART alerts or analog alarms.

3. Diagnostic Log – The transmitter logs up to ten device status events,
each associated with the time stamp of when the event occurred.
Referencing this log allows for better understanding of the device health
and can be used in conjunction with device troubleshooting.

4. Variable Log – The transmitter logs the following values: Minimum and
Maximum Pressure and Minimum and Maximum Temperature with
independent time stamped values. The transmitter also logs total
elapsed time in over-pressure or over-temperature conditions and
number of pressure or temperature excursions outside of sensor limits.

5. Process Alerts – These are configurable alerts for both process pressure
and sensor temperature. Users can receive a HART alert if pressure or
temperature exceeds threshold limits. The time stamp of when the alert
occurred and the number of alert events is also recorded in the
transmitter. When alert is active, this notification is displayed on the LCD.

6. Service Alerts – This is a configurable service reminder that generates a
HART alert after user-specified time has expired. When alert is active,
this notification is displayed on the LCD.

7. Time Stamp – The diagnostic electronics board includes an embedded
Operational Hours clock whose purpose is two-fold.

a. Provides the total number of operating hours of the transmitter.

b. Provides an elapsed “Time Since” event indication or time stamping

for all diagnostics.

All time values are non-volatile and displayed in the following format:
YY:DDD:hh:mm:ss (years:days:hours:minutes:seconds). The time
stamping capability significantly enhances the user’s ability to
troubleshoot measurement issues, particularly transient events that may
be too fast to capture with DCS or PLC trending or historian capabilities.

USER INTERFACE The 3051S with Advanced HART Diagnostic Suite can be used with any asset

management software that supports Electronic Device Description Language
(EDDL) or FDT/DTM.

Advanced HART Diagnostics is best viewed and configured using the latest
Device Dashboard interface based on Human Centered Design concepts.
The Device Dashboard can be obtained with DD revision 3051S HDT Dev. 3
Rev. 1.

The following screen shots are taken from Emerson Process Management’s
AMS™ Device Manager, version 10.5. All screens shown are based on the
Device Dashboard interface.

Figure 7-1 is the landing screen for the 3051S with Advanced HART
Diagnostic Suite. The device status will change if any device alerts are active.
Graphical gauges provide quick reading of the primary purpose variables.
Shortcut buttons are available for the most common tasks.

Each diagnostic allows the user to select a type of action to take if the
diagnostic is tripped.

None – Transmitter provides no indication that any trip values were exceeded

or the diagnostic is turned off.

Alert Unlatched – Transmitter generates digital HART alert and does not

affect the 4 – 20 mA signal. When conditions return to normal or within
threshold levels, the alert is automatically cleared.

Alert Latched – Transmitter generates digital HART alert and does not affect

the 4 – 20 mA signal. When conditions return to normal, an alert reset is
required to clear the status. This type of alert action is recommended if a 3rd
party alert monitor software is likely to miss alerts due to slow polling of HART
data.

Alarm – Transmitter drives mA output to the configured Failure Alarm level

(HIGH or LOW).

STATISTICAL PROCESS
MONITORING

Introduction Statistical Process Monitoring (SPM) provides a means for early detection of

abnormal situations in a process environment. The technology is based on
the premise that virtually all dynamic processes have a unique noise or
variation signature when operating normally. Changes in these signatures
may signal that a significant change will occur or has occurred in the process,
process equipment, or transmitter installation. For example, the noise source
may be equipment in the process such as a pump or agitator, the natural
variation in the DP value caused by turbulent flow, or a combination of both.

The sensing of the unique signature begins with the combination of the
Rosemount 3051S pressure transmitter and software resident in the
diagnostic electronics to compute statistical parameters that characterize and
quantify the noise or variation. These statistical parameters are the mean,
standard deviation, and coefficient of variation of the input pressure. Filtering
capability is provided to separate slow changes in the process due to setpoint
changes from the process noise or variation of interest. Figure 7-2 shows an
example of how the standard deviation value is affected by changes in noise
level while the mean or average value remains constant. Figure 7-3 shows an
example of how the coefficient of variation is affected by changes in the
standard deviation and mean.

Figure 7-2. Changes in process
noise or variability and affect on
statistical parameters

The calculation of the statistical parameters within the device is accomplished
on a parallel software path used to filter and compute the primary output
signal (such as the 4 - 20 mA output). The primary output is not affected in
any way by this additional capability.

Standard Deviation increases or decreases with changing noise level.

CV is stable if Mean is proportional to Standard Deviation.

SPM provides statistical information to the user in two ways. First, the
statistical parameters can be made available to the host system directly via
HART communication protocol or HART to other protocol converters. Once
available, the system can make use of these statistical parameters to indicate
or detect a change in process conditions. In the simplest example, the
statistical values may be stored in a data historian. If a process upset or
equipment problem occurs, these values can be examined to determine if
changes in the values foreshadowed or indicated the process upset. The
statistical values can then be made available to the operator directly, or made
available to alarm or alert software.

The second way for SPM to provide statistical information is with software
embedded in the 3051S. The 3051S uses SPM to baseline the process noise
or signature via a learning process. Once the learning process is completed,
the user can set thresholds for any of the statistical parameters. The device
itself can then detect significant changes in the noise or variation, and
communicate an alarm via the 4 – 20 mA output and/or alert via HART.
Typical applications are detection of plugged impulse lines, change in fluid
composition, or equipment related problems.

Overview A block diagram of the SPM diagnostic is shown in Figure 7-4. The pressure

process variable is input to a module where basic high pass filtering is
performed on the pressure signal. The mean (or average) is calculated on the
unfiltered pressure signal, the standard deviation calculated from the filtered
pressure signal. These statistical values are available via HART and handheld
communication devices like the 375 Field Communicator or asset
management software like Emerson Process Management’s AMS™ Device
Manager. The values can also be assigned as secondary variables from the
device for 4-20 mA communication to the user through other devices like the
Smart Wireless THUM or Rosemount 333 HART Tri-loop.

SPM also contains a learning module that establishes the baseline values for
the process. Baseline values are established under user control at conditions
considered normal for the process and installation. These baseline values are
made available to a decision module that compares the baseline values to the
most current statistical values. Based on sensitivity settings and actions
selected by the user via the control input, the diagnostic generates alarms,
alerts, or takes other actions when a significant change is detected in either
value.

Figure 7-5. Simplified SPM
flowchart

Rosemount 3051S Series

Further detail of the operation of the SPM diagnostic is shown in the
Figure 7-5 flowchart. This is a simplified version showing operation using the
default values. While SPM continuously calculates the mean, standard
deviation, and coefficient of variation values, the learning and decision
modules must be turned on to operate. Once enabled, SPM enters the
learning/verification mode and the status will be “Learning”. The baseline
statistical values are calculated over a period of time controlled by the user
(Learning/Monitoring Period; default is 3 minutes). A check is performed to
make sure that the process has a sufficiently high noise or variability level
(above the low level of internal noise inherent in the transmitter itself). If the
level is too low, the diagnostic will continue to calculate baseline values until
the criteria is satisfied (or turned off). A second set of values is calculated and
compared to the original set to verify that the measured process is stable and
repeatable. During this period, the status will change to “Verifying”. If the
process is stable, the diagnostic will use the last set of values as baseline
values and change to “Monitoring” status. If the process is unstable, the
diagnostic will continue to verify until stability is achieved. The stability criteria
are also user defined.

7-7

Rosemount 3051S Series

In the “Monitoring” mode, statistical values of mean, standard deviation, and
coefficient of variation are continuously calculated, with new values available
every second. When using mean and standard deviation as the SPM
variables, the mean value is compared to the baseline mean value. If the
mean has changed by a significant amount, the diagnostic can automatically
return to the “Learning” mode. The diagnostic does this because a significant
change in mean is likely due to a change in process operation and can result
in a significant change in noise level (i.e. standard deviation) as well. If the
mean has not changed, the standard deviation value is compared to the
baseline value. If the standard deviation has changed significantly and
exceeds configured sensitivity thresholds, this may indicate a change has
occurred in the process, equipment, or transmitter installation and a HART
alert or analog alarm is generated.

For DP flow applications where the mean pressure is likely to change due to
changing process operation, the recommended SPM variable for process
diagnostics is the coefficient of variation. Since the coefficient of variation is
the ratio of standard deviation to mean, it represents normalized process
noise values even when the mean is changing. If the coefficient of variation
changes significantly relative to the baseline and exceeds sensitivity
thresholds, the transmitter can generate a HART alert or analog alarm.

NOTE

SPM diagnostic capability in the Rosemount 3051S HART pressure
transmitter calculates and detects significant changes in statistical parameters
derived from the input pressure signal. These statistical parameters relate to
the variability of and the noise signals present in the pressure signal. It is
difficult to predict specifically which noise sources may be present in a given
pressure measurement application, the specific influence of those noise
sources on the statistical parameters, and the expected changes in the noise
sources at any time. Therefore, Rosemount cannot absolutely warrant or
guarantee that SPM will accurately detect each specific condition under all
circumstances.

The statistical values of mean, standard deviation, and coefficient of variation
can be made available to other systems or data historians via HART
communication. WirelessHART adaptor, such as the Smart Wireless THUM
can also be used to obtain additional variables. Devices that convert HART
variables to analog 4-20 mA outputs, such as the Rosemount 333 Tri-Loop
can also be used.

Statistical values can be assigned to be 2nd variable, 3rd variable, or 4th
variable. This is accomplished through Variable Mapping. See Figure 7-6.

Configuration screens.

• Turn on the diagnostic from the SPM Status screen.

The configuration process starts with Baseline Configuration, Figure 7-9 on
page 7-11. The configurable fields are:

SPM Variable:

This is the statistical variable to be used for SPM diagnostic detection.

Stdev & Mean (default)

Standard deviation and mean of the process are calculated. Users can set
independent sensitivity thresholds for both statistical variables.

Coefficient of Variation (CV)

CV is calculated from the ratio of standard deviation to mean and is better
suited for DP flow applications where the mean pressure is likely to
change due to changing process operation. CV puts standard deviation in
context of the mean and is represented as a % value.

Figure 7-10. Effect of
Learn/Monitor Period on
Statistical Values

Learn/Monitor Period:

This is the learning and monitoring time period that SPM diagnostic uses to
sample the pressure signal. The mean and standard deviation or coefficient of
variation values determined during the learning period will become the
Baseline values. Decreasing this period can speed up the set up time and is
recommended for stable process operations. Increasing this value will give a
better baseline value for noisier processes. If false trips for “High Variation
Detected” are occurring due to rapid changes in the process and statistical
value, increasing the learning period is recommended. The
Learning/Monitoring Period is always set in minutes. The default value is 3
minutes and the valid range is 1 to 60 minutes.

Figure 7-10 illustrates the effect of Learn/Monitor Period on the statistical
calculations. Notice how a shorter sampling window of 3 minutes captures
more variation (e.g. plot looks noisier) in the trend. With the longer sampling
window of 10 minutes, the trend looks smoother because SPM uses process
data sampled over a longer period of time.

Rosemount 3051S Series

Power Interruption Action

This is used to direct what the diagnostic should do in the case of a power
interruption or if the diagnostic is manually disabled and then enabled. The
options are:

Monitor (default)

When SPM restarts, the diagnostic returns to the Monitoring mode
immediately and uses the baseline values computed before the
interruption.

Relearn

When SPM restarts, the diagnostic enters the Learning mode and will
recalculate new baseline values.

Low Pressure Cut-off

This is the minimum pressure required to operate the diagnostic with
Coefficient of Variation selected as the statistical variable. The coefficient of
variation is a ratio of standard deviation to mean and is defined for non-zero
mean values. When the mean value is near zero, the coefficient of variation is
sensitive to small changes in the mean, limiting its usefulness. Default value
is 1% of upper sensor limit.

Insufficient Variability

The SPM diagnostic uses process noise to baseline the process and detect
abnormal situations. Typically the Insufficient Variability check is on to ensure
there is sufficient noise for proper operation. In a quiet application with very
minimal process noise, this setting can be turned off. The default setting is
ON.

Parameter Definition

On (default) Perform insufficient variation check
Off Do not perform insufficient variation check

Standard Deviation Difference, Mean Difference

If these difference values are exceeded during the Verification mode, SPM
diagnostic will not start Monitoring mode and will continue verifying the
baseline. If SPM diagnostic will not leave the Verification mode, these values
should be increased. If the diagnostic still remains in the Verification mode
with the highest level, the Learning/Monitoring period should be increased.

Parameter Definition

None Do not perform any verification checks for standard deviation.
10% If the difference between baseline standard deviation value and the

verification value exceeds 20%, diagnostic will stay in Verification
mode.

Tu rning On the SPM Diagnostic

The SPM diagnostic is enabled by selecting On for “SPM Mode”, shown on
Figure 7-14. Upon enabling SPM, the diagnostic will automatically begin
“Learning” with the following exception: if valid baseline values have been
previously established and “Monitor” has been selected as the option for
Power Interruption on the Baseline Configuration screen, then the diagnostic
will bypass Learning and begin Monitoring immediately. The diagnostic status
will stay in the Learning mode for the Learning Period specified on the
Baseline Configuration screen. After the learning period is complete, the
Mode will change to Verifying and a blue line will appear on the charts
indicating the learned baseline value. Upon completion of the Verify mode, the
diagnostic will use the parameters selected on the Verification Criteria page to
validate the baseline value. After the Verifying period the Mode will switch to
Monitoring and grey lines that indicate the sensitivity setting will appear on the
charts.

Rosemount 3051S Series

The LCD will also indicate the diagnostic condition. The “Time Since
Detection” clock in the Time Stamp box will start incrementing until the
statistical value is returned to normal. If the diagnostic alert is latched, the
“Time Since Detection” clock will continue to increment until the alert is reset
or SPM diagnostic is turned off.

Interpreting Results

The SPM diagnostic can be used to detect installation, process and
equipment changes, or problems. However, as the diagnostic is based on
detecting changes in process noise or variability, there are many possible
reasons or sources for the change in values and detection. Following are
some possible causes and solutions if a diagnostic event is detected:

an eventual plug on the other side.

a) If aeration is undesired, take necessary steps to eliminate
aeration.
b) If the measurement is DP flow and aeration is not desired,
move primary element to another location in the process piping
to ensure it remains full (no air) under all conditions.

If liquid is undesired, take necessary steps to eliminate liquid in
gas or steam flow.
If some liquid is normal, and error correction in the gas flow
measurement is being done (such as an over-reading in wet
natural gas measurements), you may need to determine the
volume fraction of the liquid (e.g. using a test separator) and a
new error correction factor for the gas flow measurement.

If solids are undesired, take necessary steps to eliminate.

Review control valve or loop for control problems.

Check process equipment.

Rapid changes in the process variable can result in indication
of high variation. If undesired, increase Alert Delay value
(default is 60 seconds). Increase the Learn/Monitor period
(default is 3 minutes).

Troubleshooting the SPM
Diagnostic

NOTE

Rosemount cannot absolutely warrant or guarantee that Statistical Process
Monitoring will accurately detect each specific abnormal condition under all
circumstances. Standard maintenance procedures and safety precautions
should not be ignored because SPM diagnostic is enabled.

Users are encouraged to pretest the SPM diagnostic if possible. For example,
if the diagnostic is to be used to detect plugged impulse lines, and if root
valves are present in the installation, the user should set up the diagnostic as
described earlier, and then alternately close the high and the low side root
valve to simulate a plugged impulse line. Using the SPM Status screen, the
user can then note the changes to the standard deviation or coefficient of
variation under the closed conditions and adjust the sensitivity values as
needed.

Process is unstable. Increase learning sensitivity
checks (Verification Criteria screen). If this does
not correct the issue, increase the learning
verification period to match or exceed the cycle
time of the instability of the process. If maximum
time does not correct the problem, process is not
a candidate for SPM diagnostic. Correct stability
issue or turn off diagnostic.

With the condition present, but the process
operating, go to the SPM Status or Operational
Values screen and note the current statistical
values and compare to the baseline and
threshold values. Adjust the sensitivity values
until a trip of the diagnostic occurs.

The most likely cause is a fast change in the
value of the process variable. Direction of the
change is not important. Increase the
learning/monitoring period to better filter out
increases in standard deviation.

POWER ADVISORY
Introduction The Power Advisory diagnostic provides a means to detect issues that may

jeopardize the integrity of the electrical loop. Some examples are: water
entering the wiring compartment and makes contact with the terminals, an
unstable power supply nearing end of life, or heavy corrosion on the
terminals.

This technology is based on the premise that once a transmitter is installed
and powered up, the electrical loop has a baseline characteristic that reflects
the proper installation. If the transmitter terminal voltage deviates from the
baseline and outside the user configured threshold, the 3051S can generate a
HART alert or analog alarm.

To make use of this diagnostic, the user must first create a baseline
characteristic for the electrical loop after the transmitter has been installed.
The loop is automatically characterized with the push of a button. This creates
a linear relationship for expected terminal voltage values along the operating
region from 4 – 20 mA, see Figure 7-16.

region

7-20

Reference Manual

00809-0100-4801, Rev FA
October 2010

Rosemount 3051S Series

Overview The transmitter is shipped with Power Advisory off as default and without any

loop characterization performed. Once the transmitter is installed and
powered up, loop characterization must be performed for Power Advisory
diagnostic to function.

When the user initiates a loop characterization, the transmitter will check to
see if the loop has sufficient power for proper operation. Then the transmitter
will drive the analog output to both 4mA and 20mA to establish a baseline and
determine the maximum allowable terminal voltage deviation. Once this is
complete, the user enters a sensitivity threshold called “Terminal Voltage
Deviation Limit” and a check is in place to make sure this threshold value is
valid.

Once the loop has been characterized and Terminal Voltage Deviation Limit is
set, Power Advisory actively monitors the electrical loop for deviations from
the baseline. If the terminal voltage has changed relative to the expected
baseline value, exceeding the configured Terminal Voltage Deviation Limit,
the transmitter can generate an alert or alarm.

NOTE

Power Advisory diagnostic in the Rosemount 3051S HART pressure
transmitter monitors and detects changes in the terminal voltage from
expected values to detect common failures. It is not possible to predict and
detect all types of electrical failures on the 4-20mA output. Therefore,
Rosemount cannot absolutely warrant or guarantee that Power Advisory
Diagnostic will accurately detect failures under all circumstances.

Figure 7-19. Voltage Deviation
Limit

The Power Advisory configuration screen allows users to characterize the
loop and configure the Terminal Voltage Deviation Limit and the Action. Two
instances of loop characterization data are recorded and presented on this
screen: “Baseline” and “Previous Baseline”. Baseline represents values from
the most recent loop characterization whereas Previous Baseline represents
values recorded prior to the most recent characterization.

Terminal Voltage

This field shows the current terminal voltage value in Volts. The terminal
voltage is a dynamic value and is directly related to the mA output value.

Terminal Voltage Deviation Limit +/-

The Terminal Voltage Deviation Limit should be set large enough that
“expected” voltage changes do not cause false failures. The default value of

1.5V will accommodate typical deviation of customer power supply voltage
and loop tests (amp meters connected across the test diode on the terminal
block). This value should be increased if your loop has additional “expected”
variation.

Severe changes in the electrical loop may inhibit HART communication or the ability to
reach alarm values. Therefore, Rosemount cannot absolutely warrant or guarantee that
the correct Failure Alarm level (HIGH or LOW) can be read by the host system at the
time of annunciation.

Resistance

This value is the calculated resistance of the electrical loop (in Ohms)
measured during the Characterize Loop procedure. Changes in the
resistance may occur due to changes in the physical condition of the loop
installation. Baseline and Previous Baselines can be compared to see how
much resistance has changed over time.

Power Supply

This value is the calculated power supply voltage of the electrical loop (in
Volts) measured during the Characterize Loop procedure. Changes in this
value may occur due to degraded performance of the power supply. Baseline
and Previous Baselines can be compared to see how much the power supply
has changed over time.

Characterization Time Stamp

This is the time stamp or elapsed time of the loop characterization event. All
time values are non-volatile and displayed in the following format:
YY:DDD:hh:mm:ss (years:days:hours:minutes:seconds).

Characterize Loop

Loop characterization must be initiated when the transmitter is first installed or
when electrical loop characteristics have been intentionally altered. Examples
include more transmitters being added onto the loop, modified power supply
level or loop resistance of the system, changing the terminal block on the
transmitter, or adding the Smart Wireless THUM to the transmitter. Another
case of required re-characterization is if the diagnostic electronics is taken out
of an existing 3051S transmitter and placed in a new 3051S installed on a
different loop.

NOTE

Power Advisory diagnostic is not recommended for transmitters operating in
HART Burst Mode (fixed current mode) or multidrop.

The loop has been severely degraded and the host system is not
able to read the proper mA output from the transmitter. This may
occur if water floods the terminal compartment and “shorts out” the
+ to – terminals or the terminals to chassis. This is most likely to
occur if the loop resistor is connected to the + side of the power
supply. Repair the damaged loop. Consider setting alarm direction
to HIGH.

The loop has been severely degraded and the host system is not

Diagnostic will not trip if loop characterization was performed when
the loop was already damaged. Repair damaged loop and
re-characterize.

Re-characterize the loop and compare the baseline with the
previous baseline. Resistance changes may indicate poor or
intermittent connections. Power supply voltage changes may
indicate unstable supply. Test for the presence of AC voltage using
an AC DVM or oscilloscope. Adding an amp meter across the test
diode will cause voltage changes of up to 1V. If all conditions look
acceptable, increase the terminal voltage deviation.

mA Output Diagnostic The mA Output Diagnostic measures the actual 4 – 20 mA output from the

transmitter’s Digital-to-Analog converter and compares it against the output
by the transmitter’s microprocessor. If the measured value deviates from the
expected value by 2% or more, the diagnostic will generate an alarm or alert.

NOTE

The default trip action for mA Output Diagnostic is set to Alarm. For use in
SIS, the trip action must not be changed or the proper safety coverage stated
on the FMEDA will not be realized.

Transmitter Power
Consumption

Transmitter Power Consumption diagnostic monitors for excessive current
draw by the transmitter. This diagnostic is used to detect a potential on-scale
failure due to current leakage or failing electronics.

NOTE

If trip action is set to Alarm, the transmitter will drive the 4 – 20 mA output to
fail HIGH regardless of the alarm direction configured by the alarm switch.

remap as necessary to assign variables intended for use with the THUM.

2. Configure the Network ID and Join Key in order for the THUM to join
wireless network.

3. Configure Update Rate for the THUM. This is frequency at which HART
data is taken and transmitted over the wireless network.

4. Connect the 3051S to the THUM, as shown in Figure 7-27 on page 7-34,
and make sure there is at least 250 Ohms resistance in the loop.

NOTE

The Smart Wireless THUM Adapter has a minimum update rate of 8 seconds
and may not capture alerts that appeared in between updates. It is
recommended to set diagnostic trip action to “Alert Latched” to minimize
chance of missed alerts in between updates.

NOTE

When using Power Advisory Diagnostic and the THUM to detect changes on
the electrical loop, a re-characterization of the loop must be performed when
the THUM is installed for the first time.

The Rosemount 333 HART Tri-Loop can be used in conjunction with the
Rosemount 3051S with Advanced HART Diagnostics to acquire up to three
more variables via 4-20mA analog signals. The additional three outputs are
selected by the user and can include: Pressure, Temperature, Scaled
Variable, Standard Deviation, Mean, or Coefficient of Variation.

SAFETY
INSTRUMENTED
SYSTEMS (SIS)
CERTIFICATION

3051S Safety Certified
Identification

The safety-critical output of the 3051S with Advanced HART Diagnostic is
provided through a two-wire, 4 - 20 mA signal representing pressure. The
3051S safety certified pressure transmitter is certified to: Low Demand; Type
B.
SIL 2 for random integrity @ HFT=0
SIL 3 for random integrity @ HFT=1
SIL 3 for systematic integrity

All 3051S transmitters must be identified as safety certified before installing
into SIS systems.

NOTE

There are three versions of safety certified 3051S pressure transmitters. For
transmitters with a yellow SIS circuit board installed (Output code B), please
refer to Manual Supplement 00809-0700-4801. For transmitters without the
Advanced HART Diagnostics circuit board installed, please refer to Section 6:
Safety Instrumented Systems.

To identify a safety certified 3051S with Advanced HART Diagnostics:

1. Connect a HART host to the transmitter.

2. Check transmitter Revision numbers to verify that Electronics SW rev is
10 or higher and Sensor SW rev is 5 or higher.

Fast Key Sequence - 1, 3, 5, 3

3051S SIS Installation No special installation is required in addition to the standard installation

3. Verify that option code DA2 is included in the transmitter model code.

practices outlined in this document. Always ensure a proper seal by installing
the electronics housing cover(s).

Environmental limits are available in the 3051S Product Data Sheet
(document number 00813-0100-4801). This document can be found at

http://www2.emersonprocess.com/en-US/brands/rosemount/Documentation-and-Drawings/Prod
uct-Data-Sheets/Pages/index.aspx

The loop should be designed so the terminal voltage does not drop below

12.0 Vdc when the transmitter output is 23.0 mA.

Security switch should be in the “ON” position during normal operation. See
Figure 7-30 on page 7-38.

Use any HART-compliant master to communicate with and verify
configuration of the 3051S Safety Certified transmitter with Advanced HART
Diagnostics.

For more information on the 375 Field Communicator see document
00809-0100-4276. AMS help can be found in the AMS on-line guides within
the AMS system.

NOTE

Transmitter output is not safety-rated during the following: configuration
changes, multidrop, and loop test. Alternative means should be used to
ensure process safety during transmitter configuration and maintenance
activities.

Statistical Process Monitoring and Power Advisory Diagnostics are shipped
with a default configuration. Both these diagnostics must be configured and
the trip action set to Alarm before any additional diagnostic coverage can be
realized. The default trip action for mA Output Diagnostic is set to Alarm and
must not be changed or proper diagnostic coverage will not be realized.

Damping

User-selected damping will affect the transmitters ability to respond to

changes in the applied process. The damping value + response time should

not exceed the loop requirements.

Proof Test

The following proof tests are recommended.
Proof test results and corrective actions taken must be documented at
http://rosemount.d1asia.ph/rosemount/safety/ReportAFailure_newweb.asp
(to report a failure) in the event that an error is found in the safety functionality.
All proof test procedures must be carried out by qualified personnel.

Use “Fast Key Sequence” on page 3-6 to perform a Loop Test, Analog Output
Trim, or Sensor Trim. Security switch should be in the “OFF” position during
proof test execution and repositioned in the “ON” position after execution.

Simple Proof Test

The simple suggested proof test consists of a power cycle plus reasonability
checks of the transmitter output. This test will detect ~ 41% of possible DU
failures in the device.

Required tools: Field Communicator and mA meter.

1. Bypass the safety function and take appropriate action to avoid a false
trip.

2. Use HART communication to set the transmitter in fixed current mode.
For the Emerson Field Communicator, enter Fast Key Sequence 3, 5, 1.
Select “4 Other.”

3. Enter the milliamp value representing a high alarm state.

4. Check the reference meter to verify the mA output corresponds to the
entered value.

5. Enter the milliamp value representing a low alarm state.

6. Check the reference meter to verify the mA output corresponds to the
entered value.

7. Remove the bypass and otherwise restore normal operation.

8. Document the test results per your requirements.

9. Place the Security switch in the “ON” position.

Rosemount 3051S Series

Comprehensive Proof Test

The comprehensive proof test consists of performing the same steps as the
simple suggested proof test but with a two point calibration of the pressure
sensor in place of the reasonability check. This test will detect ~ 87% of
possible DU failures in the device.

Required tools: Field Communicator and pressure calibration equipment.

1. Bypass the safety function and take appropriate action to avoid a false
trip.

2. Perform Proof Test 1.

3. Perform a minimum two point sensor calibration check using the 4-20
mA range points as the calibration points.

4. Check the reference mA meter to verify the mA output corresponds to
the pressure input value.

5. If necessary, use “Choosing a Trim Procedure” on page 4-5 of the 3051S
Reference Manual.

6. Document the test results per your requirements.

7. Remove the bypass and otherwise restore normal operation.

8. Place the Security switch in the “ON” position.

NOTE

The user determines the proof test requirements for impulse piping.
