Write Protect and Failure
Mode Alarm Jumpers
(HART)

After the transmitter has been configured, the configuration data can be
protected by moving the write protect jumper. When this jumper is installed,
the transmitter does not allow any changes to its configuration memory.

As part of its normal operation, the 3095 continuously monitors its own
operation. The automatic diagnostic routine is a timed series of checks
repeated continuously. If the diagnostic routine detects a failure in a
transmitter, the transmitter drives its output either below 3.75 mA or above

21.75 mA depending on the position of the failure mode jumper.

Both of these jumpers are located on the electronics board just inside the
electronics housing cover (see Figure 2-1). To avoid exposing the transmitter
electronics to the plant environment after installation, set these jumpers
during the commissioning stage on the bench.

When shipped from the factory, the write protect jumper is set to “OFF,” and
the alarm jumper is set to “High” unless specified differently by ordering the
C2 (Custom Configuration) Option Code.

Failure Mode Alarm vs. Saturation Output Values

The failure mode alarm output levels differ from the output values that occur
when applied pressure is outside the range points. When pressure is outside
the range points, the analog output continues to track the input pressure until
reaching the saturation value listed below; the output does not exceed the
listed saturation value regardless of the applied pressure. For example, for
pressures outside the 4–20mA range points, the output saturates at 3.9 mA or

20.8 mA. When the transmitter diagnostics detect a failure, the analog output
is set to a specific alarm value that differs from the saturation value to allow
for proper troubleshooting.

Level 4–20 mA Saturation Value 4–20 mA Alarm Value

Low 3.9 mA 3.75 mA

High 20.8 mA 21.75 mA

NOTE

The preceding output values can be altered by an analog output
trim procedure.

Use the following steps to change the jumper settings:

Security and Simulate
Jumpers (FOUNDATION
Fieldbus)

Security

After configuring the transmitter, you may want to protect the configuration
data from unwarranted changes. Each transmitter is equipped with a security
jumper that can be positioned “ON” to prevent the accidental or deliberate
change of configuration data. The jumper is located on the front side of the
electronics module and is labeled SECURITY (see Figure 2-1).

Simulate

The simulate jumper is used in conjunction with the Analog Input (AI) function
block. This switch is used to simulate the measurement and is used as a
lock-out feature for the AI function block. To enable the simulate feature,
insert the jumper across “ENABLE” (see Figure 2-1) while the transmitter is
powered.

NOTE

When power is cycled to the transmitter, simulate is automatically disabled
regardless of the position of the jumper. This prevents the transmitter from
being accidentally left in simulate mode. Therefore, to enable the simulate
feature, the jumper must be inserted after power is applied to the transmitter.

CONSIDERATIONS

General The accuracy of a flow or pressure measurement depends on proper

installation of the transmitter and impulse piping. The piping between the
process and the transmitter must accurately transfer the pressure in order to
obtain accurate measurements. Mount the transmitter close to the process
and use minimum impulse piping to achieve best accuracy. Keep in mind the
need for easy access, safety of personnel, practical field calibration, and a
suitable transmitter environment. In general, install the transmitter to minimize
vibration, shock, and temperature fluctuations.

The following paragraphs discuss the factors necessary for a successful
transmitter installation.

Mechanical The Rosemount 3095 may be panel-mounted, wall-mounted, or attached to a

two-inch pipe with an optional mounting bracket. Figure 2-2 illustrates 3095
mounting configurations, “Dimensional Drawings” on page A-9 shows the
transmitter dimensions, and Figure 2-3 illustrates example installations.

Figure 2-2. Mounting
Configurations.

Taps Different measurement conditions require different piping configurations.

Liquid Flow

For liquid flow measurement, place taps on the side of the line to prevent
sediment deposits, and mount the transmitter beside or below these taps so
gases can vent into the process line.

Gas Flow

For gas flow measurement, place taps in the top or side of the line and mount
the transmitter beside or above the taps so liquid will drain into the process
line.

Steam Flow

For steam flow measurement, place taps to the side of the line, with the
transmitter mounted below the taps to ensure the impulse piping remains
filled with condensate.

NOTE

When the transmitter is oriented on its side, the Coplanar

™

flange may be
mounted to ensure proper venting or draining. Mount the flange as shown in
Figure 2-3 so that the drain/vent connections are on the bottom half of the
flange for gas service, or on the top half of the flange for liquid service.

NOTE

In steam service, lines should be filled with water to prevent contact of the live
steam with the transmitter.

Impulse Piping Impulse piping, which is the piping between the process and the transmitter,

must accurately transfer the pressure in order to obtain accurate
measurements. In this pressure transfer, there are five possible sources of
error: leaks, friction loss (particularly if purging is used), trapped gas in a liquid

2-6

line, liquid in a gas line, and temperature-induced or other density variation
between the impulse piping.

Reference Manual

00809-0100-4716, Rev JA
May 2008

Rosemount 3095 MultiVariable

The best location for the transmitter in relation to the process pipe depends on
the process. Consider the following guidelines in determining transmitter
location and placement of impulse piping:

• Keep impulse piping as short as possible.

• Slope the impulse piping at least one inch per foot (8 centimeters per
meter) upward from the transmitter toward the process connection for
liquid.

• Slope the impulse piping at least one inch per foot (8 centimeters per
meter) downward from the transmitter toward the process connection
for gas.

• Avoid high points in liquid lines and low points in gas lines.

• Make sure both impulse legs are the same temperature.

• Use impulse piping large enough to avoid friction effects and prevent
blockage.

• Vent all gas from liquid piping legs.

• When using a sealing fluid, fill both piping legs to the same level.

• When purging is necessary, make the purge connection close to the
process taps and purge through equal lengths of the same size pipe.

• Avoid purging through the transmitter.

• Keep corrosive or hot (above 250 °F [121 °C]) process material out of
direct contact with the sensor module and flanges.

• Prevent sediment deposits in the impulse piping.

• Keep the liquid head balanced on both legs of the impulse piping.

• Avoid conditions that might allow process fluid to freeze within the
process flange.

NOTE

For steam service, do not blow down impulse piping through the transmitter.
Flush the lines with the blocking valves closed and refill the lines with water
before resuming measurement.

Environmental Mount the transmitter to minimize ambient temperature changes.

“Specifications” on page A-1 lists the transmitter temperature operating limits.
Mount the transmitter to avoid vibration and mechanical shock, and to avoid
external contact with corrosive materials.

Access Requirements When choosing an installation location and position, take into account the

need for access to the transmitter.

Process Flange Orientation

The process flanges must be oriented so that process connections can be
made. In addition, consider the possible need for a testing or calibration
input.

Drain/vent valves must be oriented so that process fluid is directed away from
technicians when the valves are used.

Rosemount 3095 MultiVariable

Housing Rotation

The electronics housing may be rotated to improve field access to the two
compartments. To rotate the housing less than 90 degrees, release the
housing rotation set screw and turn the housing not more than 90 degrees
from the orientation shown in Figure 2-3 on page 2-6. To rotate the
housing greater than 180 degrees, follow the disassembly procedure on
page 6-8.

Rotating the housing greater than 180 degrees without performing the disassembly
procedure may damage the 3095 sensor module.

Terminal Side of Electronics Housing

• Wiring connections are made through the conduit openings on the top
side of the housing.

• The field terminal side is marked on the electronics housing.

• Mount the transmitter so that the terminal side is accessible. A

0.75-inch (19-mm) clearance is required for cover removal.

• Install a conduit plug in the unused conduit opening.

Mounting Brackets

Optional mounting brackets available with the 3095 facilitate mounting to a
panel, wall, or 2-in. (51-mm) pipe. The bracket option for use with the
Coplanar flange is 316 SST with 316 SST bolts.

When installing the transmitter to one of the mounting brackets, torque the
bolts to 125 in-lb (14 n-m).

Mounting Pressure Effect

To correct for mounting position effects, the 3095 should be zero trimmed,
using the zero trim procedure described on page 3-13.

Bolt Installation
Guidelines

The following guidelines have been established to ensure a tight flange,
adapter, or manifold seal. Use only bolts supplied with the transmitter or sold
by Rosemount Inc. as a spare part to the 3095 transmitter.

The 3095 is shipped with the Coplanar flange installed with four 1.75-inch
(44-mm) flange bolts. The following bolts also are supplied to facilitate other
mounting configurations:

• Four 2.25-inch (57-mm) manifold/flange bolts for mounting the
Coplanar flange on a three-valve manifold. In this configuration, the

1.75-inch (44-mm) bolts may be used to mount the flange adapters to
the process connection side of the manifold.

• (Optional) If flange adapters are ordered, four 2.88-inch (73-mm)
flange/adapter bolts for mounting the flange adapters to the Coplanar
flange.

Stainless steel bolts supplied by Rosemount Inc. are coated with a lubricant to
ease installation. Carbon steel bolts do not require lubrication. Do not apply
additional lubricant when installing either type of bolt. Bolts supplied by
Rosemount Inc. are identified by the following head markings:

Hazardous Locations The Rosemount 3095 has an explosion-proof housing and circuitry suitable

for intrinsically safe and non-incendive operation. Individual transmitters are

Electrical (HART) The signal terminals are located in a compartment of the electronics housing

separate from the transmitter electronics.

Power Supply

The dc power supply should provide power with less than 2% ripple. The total
resistance load is the sum of the resistance of the signal leads and the load
resistance of the controller, indicator, and related pieces. Note that the
resistance of intrinsic safety barriers, if used, must be included.

NOTE

A loop resistance between 250–1100 ohms inclusive is required to
communicate with a personal computer. With 250 ohms of loop resistance, a
power supply voltage of at least 16.5 V dc is required.

If a single power supply is used to power more than one 3095 transmitter, the
power supply used, and circuitry common to the transmitters, should not have
more than 20 ohms of impedance at 1200 Hz.

Figure 2-5. Power Supply Load
Limitations.

Electrical (FOUNDATION
Fieldbus)

Proper electrical installation is necessary to prevent errors due to improper
grounding and electrical noise. Shielded, twisted pair cable should be used for
best results in electrically noisy environments. Cable Type A is recommended
by FOUNDATION fieldbus.

NOTE

After a device labeled with multiple approval types is installed, it should not be
reinstalled using any of the other labeled approval types. To ensure this, the
approval label should be permanently marked to distinguish the used from the
unused approval type(s).

2-12

Field Wiring

All power to the transmitter is supplied over the signal wiring. For best
installation practices, use a fieldbus type A cable. Do not run unshielded
signal wiring in conduit or open trays with power wiring or near heavy
electrical equipment. Do not remove the transmitter cover in explosive
atmospheres when the circuit is alive.

(1) Quick troubleshooting check: There must be at least 11.0 V dc across the transmitter

terminals.

Fieldbus Wiring Connections

Rosemount 3095 MultiVariable

NOTE

Do not apply high voltage (e.g. ac line voltage) to the transmitter terminals.
Abnormally high voltage can damage the unit.

Grounding

Signal wiring of the fieldbus segment cannot be grounded. Grounding out one
of the signal wires will shut down the entire fieldbus segment.

Shield Wire Ground

To protect the fieldbus segment from noise, grounding techniques for shield
wire usually require a single grounding point for shield wire to avoid creating a
ground loop. The ground point is typically at the power supply.

Power Connections

Use ordinary copper wire of sufficient size to ensure that the voltage across
the transmitter power terminals does not go below 9 V dc. To power the
transmitter, connect the power leads to the terminals marked “FIELDBUS
WIRING” as shown in Figure 2-7. The power terminals are polarity
insensitive, which means the electrical polarity of the power leads does not
matter when connecting to the power terminals. When wiring to screw
terminals, the use of crimped lugs is recommended. Tighten the terminal

screws to ensure adequate contact.

Grounding the
Transmitter Housing

Always ground the transmitter case in accordance with national and local
electrical codes. The most effective transmitter case grounding method is a
direct connection to earth ground with minimal impedance. Methods for
grounding the transmitter case include:

• Internal Ground Connection: The Internal Ground Connection screw
is inside the FIELD TERMINALS side of the electronics housing. The
screw is identified by a ground symbol ( ), and is standard on all
3095 transmitters.

• External Ground Assembly: This assembly is included with the
optional transient protection terminal block (Option Code T1), and it is
included with CESI/CENELEC Flameproof Certification (Option Code
E8), BASEEFA/CENELEC Intrinsic Safety Certification (Option Code
I1), and BASEEFA/CENELEC Type N Certification (Option Code N1).
The External Ground Assembly can also be ordered with the
transmitter (Option Code V5), or as a spare part (03031-0398-0001).

NOTE

Grounding the transmitter case using the threaded conduit connection may
not provide a sufficient ground. The transient protection terminal block (Option
Code T1) does not provide transient protection unless the transmitter case is
properly grounded. Use the above guidelines to ground the transmitter case.
Do not run transient protection ground wire with signal wiring; the ground wire
may carry excessive current if a lightning strike occurs.

Surges/Transients The transmitter will withstand electrical transients of the energy level usually

2-14

encountered in static discharges or induced switching transients. However,
high-energy transients, such as those induced in wiring from nearby lightning
strikes, can cause damage to the transmitter.

Optional Transient
Protection Terminal
Block

INSTALLATION

The transient terminal block can be ordered as an installed option (Option
Code T1 in the transmitter model number) or as a spare part to retrofit existing
3095 transmitters in the field. See “Spare Parts List” on page A-14.

Installation

When the transient protection terminal block is ordered as a spare part, it
must be installed in place of the standard terminal block inside the transmitter
housing. See “Removing the Electrical Housing” on page 5-8.

NOTE

The transient protection terminal block provides transient protection only if the
transmitter housing is properly grounded. See “Grounding the Transmitter
Housing” on page 2-14.

Performance

The transient protection terminal block increases the ability of the 3095
transmitter to withstand electrical transients induced by lightning, welding, or
heavy electrical equipment. With the transient protection block installed, the
3095 transmitter meets the standard performance specifications as outlined in
this product manual. In addition, the transient protection circuitry meets IEEE
Standard 587, Category B and IEEE Standard 472, Surge Withstand
Capability.

Check for Leaks 5. Check all process penetrations for leaks.

Power and Signal Wiring 6. Make field wiring connections (see Figure 2-6 or Figure 2-12). These

connections provide both power and signal wiring.

For explosion-proof installations, wiring connections must be made in accordance with
Rosemount drawing 03095-1025 or 03095-1024.

For instrinsically safe installations, wiring connections must be made in accordance
with ANSI/ISA-RP12.6, and Rosemount drawings 03095-1020 or 03095-1031.

For ALL installations, wiring connections must be made in accordance with local or
national installation codes such as the NEC NFPA 70.

NOTES

• Do not run field wiring in conduit or open trays with other power
wiring, or near heavy electrical equipment.

• Field wiring need not be shielded, but use twisted pairs for
best results.

• To ensure communication, wiring should be 24 AWG or larger
and not exceed 5,000 feet (1,500 meters).

• For connections in ambient temperatures above 140 °F (60 °C), use
wiring rated for at least 194 °F (90 °C).

a. Remove the cover on the side marked FIELD TERMINALS on the

electronics housing.

b. Connect the lead that originates at the positive side of the power

supply to the terminal marked “+ SIG” or “+ PWR.” Be sure to
include loop resistance.

NOTE

Incorrect field wiring connections may damage the 3095. Do not connect field
wiring to the “TEST +” terminals.

c. Connect the lead that originates at the negative side of the power

supply to the terminal marked “–.”

d. Plug and seal unused conduit connections on the transmitter

housing to avoid moisture accumulation in the terminal side of the
housing.

NOTE

If the conduit connections are not sealed, mount the transmitter with the
electrical housing positioned downward for drainage. Conduit should be
installed with a drip loop, and the bottom of the drip loop should be lower than
the conduit connections or the transmitter housing.

Grounding 7. Install field wiring ground (optional), and ground the transmitter case

(required).

Ground the Transmitter Case

b. The transmitter case should always be grounded in accordance

with national and local electrical codes. The most effective
transmitter case grounding method is direct connection to earth
ground with minimal impedance. Methods for grounding the
transmitter case include:

• External Ground Assembly: This assembly is included with the

transient protection terminal block. The External Ground
Assembly can also be ordered as a spare part (see “Spare
Parts List” on page A-14).

• Internal Ground Connection: Inside the FIELD TERMINALS

side of the electronics housing is the Internal Ground
Connection screw. This screw is identified by a ground symbol:

NOTE

The transient protection terminal block does not provide transient protection
unless the transmitter case is properly grounded. Use the above guidelines to
ground the transmitter case.

Do not run the transient protection ground wire with field wiring as the ground
wire may carry excessive current if a lighting strike occurs.

Grounding the transmitter case using threaded conduit connection may not
provide sufficient ground.

RTD Configuration

The RTD Config link specifies the process temperature (PT) mode. It allows
you to enable or disable PT input or to specify automatic backup mode.

When in Normal Mode, the transmitter uses the external RTD for PT
measurement. In the event of an RTD failure, the transmitter goes into alarm
condition.

When in Fixed Mode the transmitter will stay on a fixed value that is entered
by the user.

When in Backup Mode, a value is specified that the transmitter will go to in the
event the RTD fails or is disconnected. Upon failure, the transmitter will use
the backup value and set a HART status bit for PT alarm, but will not go into
alarm condition. The transmitter returns to automatic temperature sensor
readings when the RTD failure condition no longer exists.

NOTE

The fixed and backup process temperature ranges are wider than the actual
process temperature range:

Process Temperature Range: -300 to 1500 °F (-185 to 815 °C)
Fixed/Backup Temperature Range: -459 to 3500 °F (-273 to 1927 °C)

Rosemount 3095 MultiVariable

HART Tab

The HART tab is used to set some of the communications parameters that are
used by HART protocol.

• Tag: same parameter as found on the “Basic Setup” tab.

• Poll Address: users can assign a unique HART address to the 3095 to

differentiate it from other devices if set up on a multidrop network.

• Number of Response Preambles: changes the number of response

preambles for the transmitter to EA communication. Typically, this
value is set at five. Increase the value only if the transmitter is installed
in an electrically noisy environment.

• Burst Mode: must be enabled for operation with a Rosemount 333

Tri-Loop. With burst mode ON, the 3095 continuously outputs HART
parameters, eliminating the time required for the control system to
request information from the transmitter.

Burst mode is compatible with use of the analog signal. Because HART
protocol features simultaneous digital and analog data transmission, the
analog value can drive other equipment in the loop while the control system or
Tri-Loop receives the digital information.

Reference Manual

00809-0100-4716, Rev JA

May 2008

Access to information other than burst data is obtained through the normal
poll/response method of HART communication. The EA or the control system
may request any of the information that is normally available while the
transmitter is in burst mode. However, the response time to these requests
will be longer. Between each burst message sent by the transmitter, a short
pause allows the EA or control system to initiate a request. The transmitter
receives the request, processes the response message, and then continues
bursting the data approximately three times per second. When sending a new
flow configuration file from the EA, the burst mode must be OFF.

Burst mode is not compatible with Multi Dropping more than one transmitter
because there is no method to discriminate the data communications from
multiple field devices.

• Burst Option: From the pull down menu select what type of data will

be sent when the transmitter is in Burst Mode. For use with the 333
Tri-Loop, the Burst Option must be set to “process vars/crnt” (HART
CMD3).

An important step to verify the correct flow configuration was sent to the
transmitter is by running a Test Calculation. This will simulate the differential
pressure, static pressure, and process temperature and return the mass flow
output from the transmitter. To run a Test Calculation:

1. Open the Mass Flow Transducer Block.

2. Set the Mass Flow Transducer Block into Out Of Service mode.

3. Enter the parameters from the DP Flow Calculation Data Sheet in the
parameter indices shown in Table 4-2. These values must be entered
in the following units: inH

O, PSIA, and °F, respectively. (The status

2

for these values should be set to
Good_Noncascade_Nonspecific_Not Limited).

4. Write/Apply changes (As applicable for the Fieldbus host).

5. Set the block into Manual mode.

6. The Mass Flow Block will calculate the mass flow value (Index
Number 13) based on the differential pressure, static pressure, and
process temperature values that were entered. This value will be
displayed in lb/s and should agree with the calculated mass flow
value on the DP Flow Calculation Data Sheet.

Device Description

Before configuring the device, ensure the host has the appropriate Device
Description file revision for this device. The device descriptor can be found on
www.rosemount.com. The initial release of the 3095 with FOUNDATION
Fieldbus protocol is device revision 1.

Node Address The transmitter is shipped at a temporary (248) address. This will enable

FOUNDATION Fieldbus host systems to automatically recognize the device
and move it to a permanent address.

Modes The Resource, Transducer, and all function blocks in the device have modes

of operation. These modes govern the operation of the block. Every block
supports both automatic (AUTO) and out of service (OOS) modes. Other
modes may also be supported.

Changing Modes

To change the operating mode, set the MODE_BLK.TARGET to the desired
mode. After a short delay, the parameter MODE_BLOCK.ACTUAL should
reflect the mode change if the block is operating properly.

Permitted Modes

It is possible to prevent unauthorized changes to the operating mode of a
block. To do this, configure MODE_BLOCK.PERMITTED to allow only the
desired operating modes. It is recommended to always select OOS as one of
the permitted modes.

The functions performed by the block will execute. If the block has any
outputs, these will continue to update. This is typically the normal
operating mode.

Out of Service (OOS)

The functions performed by the block will not execute. If the block has any
outputs, these will typically not update and the status of any values passed
to downstream blocks will be “BAD”. To make some changes to the
configuration of the block, change the mode of the block to OOS. When
the changes are complete, change the mode back to AUTO.

MAN

In this mode, variables that are passed out of the block can be manually
set for testing or override purposes.

Other Types of Modes

Other types of modes are Cas, RCas, ROut, IMan and LOW. Some of
these may be supported by different function blocks. For more information,
see the Function Block manual (document number 00809-0100-4783).

Rosemount 3095 MultiVariable

Mass Flow Transducer Block (1200)

Contains configuration and diagnostic information to perform fully
compensated mass flow calculations. Contains the mass flow process
variable (PV). Mass flow is calculated using process differential pressure and
pressure. Temperature can be based on either process temperature or a fixed
temperature value.

LCD Transducer Block (1300)

The LCD Transducer Block is used to configure the LCD display.

Analog Input Block (1400 to 1800)

Takes the analog input data from the analog input signal and it makes
available to other function blocks. It has scaling conversion, filtering, square
root, low cut and alarm processing.

FIELDBUS

Analog Output Block (1900)

The AO block provides an analog value to generate an analog output signal. It
provides value and rate limiting, scaling conversion, fault state mechanism
and other features.

Input Selector Block (2200)

Has four analog inputs that may be selected by an input parameter or
according to a criterion as first good, maximum, middle and average.

Integrator Block (2100)

Integrates a variable in function of the time. There is a second flow input that
may be used for the following applications: net flow totalization, volume/mass
variation in vessels and precise flow ratio control.

Arithmetic Block (2300)

This calculation block provides some pre-defined equations ready for use in
applications as flow compensation, HTG, ratio control and others.

Signal Characterizer Block (2400)

Has capability for two signal characterization based on the same curve. The
second input has an option for swapping “x” to “y”, providing an easy way to
use the inverse function, which may be used in signal characterization of
read-back variables.

PID Block (2000)

Allows the selection of either the standard ISA algorithm or a series algorithm.
Additionally the Proportional, Integral and Derivative actions can be based
either on the PV or on the error. An additional enhancement provides beta
and gamma factors for proportional and derivative multipliers providing a “two
degrees of freedom” system.

4-13

Rosemount 3095 MultiVariable

Control Selector Block (2500)

The control selector is used to select the most appropriate control output
based on a preconfigured criteria. The outputs of up to three PID blocks are
accepted as inputs to the control selector. The control selector selects which
control output to pass on to downstream blocks based on user configured
criteria such as maximum, minimum, middle, or first good.

Output Splitter Block (2600)

The output splitter is used to pass the output of a single PID block to one of
two analog output blocks depending on process conditions. Applications such
as temperature control may require either heating or cooling depending on
process conditions. The output splitter allows the output of the control PID to
be sent through two different AO blocks to two different final control elements.

FEATURES and
FEATURES_SEL

The parameters FEATURES and FEATURE_SEL determine optional
behavior of the 3095.

FEATURES

The FEATURES parameter is read only and defines which features are
supported by the 3095. Below is a list of the FEATURES the 3095 supports.

UNICODE

All configurable string variables in the 3095, except tag names, are octet
strings. Either ASCII or Unicode may be used. If the configuration device is
generating Unicode octet strings, you must set the Unicode option bit.

REPORTS

The 3095 supports alert reports. The Reports option bit must be set in the
features bit string to use this feature. If it is not set, the host must poll for
alerts.

FAULT STATE

The fault state condition is set by loss of communication to an output block,
when the fault state is promoted to an output block or a physical contact.
When fault state is set, then output function bocks will perform their FSTATE
actions. The Rosemount 3095 supports fault state action. The fault state
option bit must be set in the features bit to use this feature.

SOFT W LOCK and HARD W LOCK

Inputs to the security and write lock functions include the hardware security
switch, the hardware and software write lock bits of the FEATURE_SEL
parameter, the WRITE_LOCK parameter, and the DEFINE_WRITE_LOCK
parameter.

4-14

The WRITE_LOCK parameter prevents modification of parameters within the
device except to clear the WRITE_LOCK parameter. During this time, the
block will function normally updating inputs and outputs and executing
algorithms. When the WRITE_LOCK condition is cleared, a WRITE_ALM
alert is generated with a priority that corresponds to the WRITE_PRI
parameter.

Reference Manual

00809-0100-4716, Rev JA
May 2008

Rosemount 3095 MultiVariable

The FEATURE_SEL parameter enables the user to select a hardware or
software write lock or no write lock capability. To enable the hardware security
function, enable the HW_SEL bit in the FEATURE_SEL parameter. When this
bit has been enabled the WRITE_LOCK parameter becomes read only and
will reflect the state of the hardware switch. In order to enable the software
write lock, the SW_SEL bit must be set in the FEATURE_SEL parameter.
Once this bit is set, the WRITE_LOCK parameter may be set to “Locked” or
“Not Locked.” Once the WRITE_LOCK parameter is set to “Locked” by either
the software or the hardware lock, all user requested writes as determined by
the DEFINE_WRITE_LOCK parameter shall be rejected.

The DEFINE_WRITE_LOCK parameter allows the user to configure whether
the write lock functions (both software and hardware) will control writing to all
blocks, or only to the resource and transducer blocks. Internally updated data
such as process variables and diagnostics will not be restricted by the
security switch.

The following table displays all possible configurations of the WRITE_LOCK
parameter.

FEATURES_SEL

FEATURES_SEL is used to turn on any of the supported features. The default
setting of the 3095 does not select any of these features. Choose one of the
supported features if any.

MAX_NOTIFY

The MAX_NOTIFY parameter value is the maximum number of alert reports
that the resource can have sent without getting a confirmation, corresponding
to the amount of buffer space available for alert messages. The number can
be set lower, to control alert flooding, by adjusting the LIM_NOTIFY
parameter value. If LIM_NOTIFY is set to zero, then no alerts are reported.

Damping The damping parameter in the Transducer Block may be used to filter

measurement noise. By increasing the damping time, the transmitter will have
a slower response time, but will decrease the amount of process noise that is
translated to the Transducer Block Primary Value. Because both the LCD and
AI Block get input from the Transducer Block, adjusting the damping
parameter will effect the values passed to both blocks.

NOTE

The AI Block has it's own filtering parameter called PV_FTIME. For simplicity,
it is better to do filtering in the Transducer Block as damping will be applied to
primary value on every sensor update. If filtering is done in AI block, damping
will be applied to output every macrocycle. The LCD will display value from
Transducer block.

Configuration

The Mass Flow Transducer Block is an optional licensed transducer block.
The Block is configured using the Rosemount Engineering Assistant for
F

OUNDATION fieldbus software program. The block may be configured to

utilize the process variables measured by the 3095 multivariable transmitter
to include: differential pressure, pressure (gage or absolute) and temperature.
Process variable measurements may also be used from independent
measurement devices on the F
Transducer Block can also use a fixed temperature input to calculate mass
flow.

The LCD display connects directly to the Rosemount 3095 electronics
F

OUNDATION fieldbus output board. The display indicates output and

abbreviated diagnostic messages.

The display features a two-line display and a 0-100% scaled bar graph. The
first line of five characters displays the output description, the second line of
seven digits displays the actual value, the third line of six characters displays
engineering units and the fourth line displays “Error” when the transmitter is in
alarm. The LCD display can also display diagnostic messages.

Each parameter configured for display will appear on the LCD for a brief
period before the next parameter is displayed. If the status of the parameter
goes bad, the LCD will also cycle diagnostics following the displayed variable:

Shipped from the factory, Parameter #1 is configured to display the Primary
Variable (pressure) from the LCD Transducer Block. Parameters 2 – 4 are not
