Model 3244MV
September 2002
OVERVIEW
Transmitter Enhanced measurement capability allows the Model 3244MV to communicate
multiple variables to a Profibus-PA host or configuration tool. This
temperature transmitter has the ability to accept simultaneous inputs from two
temperature sensing elements. The differential temperature measurement
capability can be used to detect sensor drift in a dual-element sensor. The
Model 3244MV with Profibus-PA combines the effects of transmitter drift,
sensor interchangeability error, temperature effects, and reference accuracy
to better account for actual process conditions and to assure maximum
accuracy.
The Model 3244MV with Profibus-PA provides superior performance in
non-critical applications involving basic process monitoring as well as
simultaneous measurement of separate and independent temperature points
with one transmitter. With this feature instrument costs are reduced by as
much as 50 percent. In addition, the multi-drop capability of Profibus-PA
results in additional savings through reduced wiring costs.
PROFIBUS Technology Profibus-PA is an all digital, serial, two-way communication system that
interconnects field equipment such as sensors, actuators, and controllers.
Profibus-PA is a Local Area Network (LAN) for instruments used in both
process and manufacturing automation. The profibus environment is the base
level group of digital networks in the hierarchy of plant networks.
Profibus-PA communication retains the desirable features of the 4–20 mA
analog system, including a standardized physical interface to the wire,
bus-powered devices on a single pair of wires, and intrinsic safety options. It
also enables additional capabilities, such as the following:
• increased capabilities due to full digital communications
• reduced wiring and wire terminations due to multiple devices on one
pair of wires
• increased selection of suppliers due to interoperability
• reduced loading on control room equipment with the distribution of
some control and input/output functions to field devices

SAFETY MESSAGES Instructions and procedures in this section may require special precautions to
ensure the safety of the personnel performing the operations. Information that
raises potential safety issues is indicated by a warning symbol ( ). Please
refer to the following safety messages before performing an operation
preceded by this symbol.
Warnings
Failure to follow these installation guidelines could result in death or serious injury:
• Make sure only qualified personnel perform the installation.
Explosions could result in death or serious injury:
• Do not remove the transmitter cover in explosive atmospheres
when the circuit is live.
• Verify that the operating atmosphere of the transmitter is consistent with the
appropriate hazardous locations certifications.
• Both transmitter covers must be fully engaged to meet
explosion-proof requirements.
Electrical shock could cause death or serious injury. If the sensor is installed in a
high-voltage environment and a fault condition or installation error occurs, high voltage may
be present on transmitter leads and terminals.
• Use extreme caution when making contact with the leads and terminals.
Process leaks could result in death or serious injury:
• Install and tighten thermowells or sensors before applying pressure, or process
leakage may result.
• Do not remove the thermowell while in operation. Removing while in operation
may cause process fluid leaks.

Model 3244MV

CONSIDERATIONS
General Electrical temperature sensors such as RTDs and thermocouples produce
low-level signals proportional to temperature. The Model 3244MV
temperature transmitter converts the analog sensor signal to a digital signal
that is relatively insensitive to lead length and electrical noise. This current
signal is then transmitted over the bus to the configuration device and the
control room.
Electrical Proper electrical installation is necessary to prevent errors due to sensor lead
resistance and electrical noise. Shielded, twisted cable should be used for
best results in electrically noisy environments. Refer to “Sensor Connections”
on page 2-9 for more information.
Power Supply
The transmitter requires between 9 and 32 V dc to operate and provide
complete functionality. The dc power supply should provide power with less
than 2% ripple.
Power Filter
A profibus segment requires a power conditioner to isolate the power supply
filter and decouple the segment from other segments attached to the same
power supply.
Mechanical The Model 3244MV transmitter can be mounted directly to the sensor or apart
from the sensor using an optional mounting bracket. Using the bracket, the
transmitter can be mounted either to a flat surface or to a 2-inch diameter pipe
(see “Mounting Brackets” on page A-7).
Mounting
The transmitter may require supplementary support under high-vibration
conditions, particularly if used with extensive thermowell lagging or long
extension fittings. Pipe-stand mounting, using one of the optional mounting
brackets, is recommended for use in high-vibration applications.
Access Requirements
When choosing an installation location and position, take into account the
need for access to the transmitter.
Electronics Housing
Mount the transmitter so the terminal side and terminal side is accessible.
Be sure to allow adequate clearance for cover removal. When adding a
LCD meter, mount the circuit-side of the transmitter in a visible position.
Tagging
2-2
Commissioning Tag
The Model 3244MV has been supplied with a removable commissioning
tag that contains both the Device ID and a space to record the device tag.
The Device ID is a unique code that identifies a particular device in the
absence of a device tag. The device tag is used as an operational
identification for the device and is usually defined by the Piping and
Instrumentation Diagram (P & ID).
Model 3244MV
When commissioning more than one device on a profibus segment, it can
be difficult to identify which device is at a particular location. The
removable tag provided with the transmitter can aid in this process by
linking the Device ID and a physical location. The installer should note the
physical location in both places on the removable commissioning tag and
tear off the bottom portion. This should be done for each device on the
segment. The bottom portion of the tags can be used for commissioning
the segment in the control system.
Environmental Temperature Environments
The transmitter will operate within specifications for ambient temperatures
between –40 and 185 °F (–40 and 85 °C).In a direct mounting configuration,
heat from the process is transferred from the thermowell to the transmitter
housing. If the expected process temperature is near or beyond the
specification limits, consider the use of additional thermowell lagging, an
extension nipple, or a remote mounting configuration to isolate the transmitter
from these excessive temperatures. Figure 2-1 provides an example of the
relationship between transmitter housing temperature rise and extension
length. Use Figure 2-1 and the accompanying example to determine
adequate thermowell extension length.

EXAMPLE:
The rated temperature specification is 85 °C. If the maximum ambient
temperature is 40 °C and the temperature to be measured is 540 °C, the
maximum allowable housing temperature rise is the rated temperature
specification limit minus the existing ambient temperature (85 – 40), or
45 °C.
As shown in Figure 2-1, an extension (E) dimension of 3.6 inches will result
in a housing temperature rise of 22 °C. An “E” dimension of 4 inches would
therefore be the minimum recommended length and would provide a
safety factor of about 25 °C. A longer “E” dimension, such as 6 inches,
would be desirable in order to reduce errors caused by transmitter
temperature effect, although in that case the transmitter would probably
require extra support. If a thermowell with lagging is used, the “E”
dimension may be reduced by the length of the lagging.

Moist or Corrosive Environments
The Model 3244MV has a highly reliable, dual-compartment housing
designed to resist moisture and corrosives. The electronics module assembly
is mounted in a compartment that is isolated from the terminal side conduit
entries. O-ring seals protect the interior of each compartment from the
environment when the covers are installed. In humid environments it is
possible for moisture to accumulate in conduit lines and drain into the
housing.
Proper installation of the transmitter can ensure maximum operation and
service life. It can also have a significant impact on preventing moisture from
accumulating in the housing. Refer to Figures 2-2 and 2-3 before mounting
the transmitter.
Mount the transmitter at a high point in the conduit run so moisture from the
conduits will not drain into the housing. If the transmitter is mounted at a low
point in the conduit run the terminal compartment could fill with water. In some
instances the installation of a poured conduit seal, such as the one pictured in
Figure 2-3, is advisable. Remove the terminal compartment cover periodically
and inspect the transmitter for moisture damage and corrosion.

CONNECT THE WIRING AND POWER UP
Field Wiring All power to the transmitter is supplied over the signal wiring. Signal wiring
should be shielded, twisted pair for best results. 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 live.
If the sensor is installed in a high-voltage environment and a fault condition or
installation error occurs, the sensor leads and transmitter terminals could
carry lethal voltages. Use extreme caution when making contact with the
leads and terminals.
NOTE
Do not apply high voltage (e.g. ac line voltage) to the transmitter terminals.
Abnormally high voltage can damage the unit. (Sensor and transmitter power
terminals are rated to 42.4 V dc.)
Power Connections Use ordinary copper wire of sufficient size to ensure that the voltage across the
transmitter power terminals does not drop below 9 V dc. To power the
transmitter, connect the power leads to the terminals marked “+” and “T” 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. No additional power wiring is needed.

Grounding Transmitters are electrically isolated to 500 V ac rms. Ground the signal
wiring at any single point, if desired. When using a grounded thermocouple,
the grounded junction serves as this point.
NOTE
Do not ground the signal wire at both ends.
Shielded Wire
Recommended grounding techniques for shielded wire usually call for a
single grounding point for each shielded wire to avoid grounding the loop. The
following two examples employ the single point grounding technique:
Example 1
1. Connect the signal wiring shield to the sensor wiring shield.
2. Ensure that the two shields are tied together and electrically isolated
from the transmitter housing.
3. Ground the shield at power supply end.
Example 2
1. Connect the sensor wiring shield to the ground terminal (located
inside the terminal compartment of the transmitter housing).
2. Cut the signal wiring shield and isolate from the transmitter housing.
3. Grounded the shield at the power supply end only. Never connect the
shield for the signal wiring to the ground terminal inside the
transmitter housing.
Transmitter Housing
Ground the transmitter housing in accordance with local electrical
requirements. The internal ground terminal is standard. An optional external
ground lug assembly (option code G1) can also be ordered if needed. This
external grounding method is recommended when using the optional transient
protector (option code T1).
Surges/Transients The transmitter will withstand electrical transients usually encountered in
static discharges or induced switching transients. However, high-energy
transients, such as those induced in wiring from nearby lightning strikes, can
damage both the transmitter and the sensor.
A transient protection will be available at a later date for adding to the Model
3244MV with Profibus-PA.

Sensor Connections The Model 3244MV transmitter is compatible with many RTD and
thermocouple sensor types. Figure 2-8 shows the correct sensor terminal
input connections on the transmitter. To ensure an adequate sensor
connection, anchor the sensor lead wires beneath the flat washer on the
terminal screw.
If the sensor is installed in a high voltage environment and a fault condition or
installation error occurs, the sensor leads and transmitter terminals could
carry lethal voltages. Use extreme caution when making contact with the
leads and terminals.
RTD or Ohm Inputs
Various RTD configurations, including 2-wire, 3-wire, 4-wire, and
compensation loop designs, are used in industrial applications. If the
transmitter is mounted remotely from a 3- or 4-wire RTD, it will operate within
specifications, without recalibration, for lead wire resistances of up to 10 ohms
per lead (equivalent to 1,000 feet of 20 AWG wire). In this case, the leads
between the RTD and transmitter should be shielded. If using only two leads
(or a compensation loop lead wire configuration), both RTD leads are in
series with the sensor element, so significant errors can occur if the lead
lengths exceed one foot of 20 AWG wire.
Figure 2-8. Transmitter Sensor
Wiring.
Thermocouple or Millivolt Inputs
For direct-mount applications, connect the thermocouple directly to the
transmitter. If mounting the transmitter remotely from the sensor, use
appropriate thermocouple extension wire. Make connections for millivolt
inputs with copper wire. Use shielding for long runs of wire.
NOTE
The use of two grounded thermocouples with a Model 3244MV is not
recommended. For applications in which the use of two thermocouples is
desired, connect either two ungrounded thermocouples, one grounded and
one ungrounded thermocouple, or one dual element thermocouple.

SET THE SWITCHES
Security After the transmitter is configured, it is possible to protect the configuration
data from unwarranted changes. Each transmitter is equipped with a security
switch that can be positioned “ON” to prevent the accidental or deliberate
change of configuration data. The switch is located on the front side of the
electronics module and is labeled SECURITY (see Figure 2-9).
Simulate The simulate switch is used in conjunction with the Analog Input (AI) function
block. This switch is used to simulate the temperature measurement and is
used as a lock-out feature for the AI function block. To enable the simulate
feature, the switch must transition from “OFF” to “ON” after power is applied to
the transmitter (see Figure 2-9). This feature prevents the transmitter from
being accidentally left in simulator mode.

SAFETY MESSAGES Instructions and procedures in this section may require special precautions to
ensure the safety of the personnel performing the operations. Information that
raises potential safety issues is indicated by a warning symbol ( ). Please
refer to the following safety messages before performing an operation
preceded by this symbol.
Warnings
Failure to follow these installation guidelines could result in death or serious injury:
• Make sure only qualified personnel perform the installation.
Explosions could result in death or serious injury:
• Do not remove the transmitter cover in explosive atmospheres
when the circuit is live.
• Verify that the operating atmosphere of the transmitter is consistent with the
appropriate hazardous locations certifications.
• Both transmitter covers must be fully engaged to meet
explosion-proof requirements.
Electrical shock could cause death or serious injury. If the sensor is installed in a
high-voltage environment and a fault condition or installation error occurs, high voltage may
be present on transmitter leads and terminals.
• Use extreme caution when making contact with the leads and terminals.
Process leaks could result in death or serious injury:
• Install and tighten thermowells or sensors before applying pressure, or process
leakage may result.
• Do not remove the thermowell while in operation. Removing while in operation
may cause process fluid leaks.

Maintenance The Model 3244MV transmitter has no moving parts and requires a minimum
amount of scheduled maintenance. The transmitter features a modular design
for easy maintenance. If a malfunction is suspected, check for an external
cause before performing the diagnostics presented below.
Sensor Checkout
If the sensor is installed in a high-voltage environment and a fault condition or
installation error occurs, the sensor leads and transmitter terminals could
carry lethal voltages.
To determine whether the sensor is causing the malfunction, either replace it
with another Rosemount sensor or connect a test sensor locally at the
transmitter. This can be very useful, especially when checking the wiring for a
remote mounted sensor. Please consult a Rosemount representative for more
information.
ELECTRONICS HOUSING
Disassembly The transmitter is designed with a dual-compartment housing; one
compartment contains the Profibus-PA electronics module assembly and the
other contains all sensor, power/communication, and internal ground lug
terminals.
The transmitter’s electronics module assembly is located in the compartment
opposite the terminal block.
Removing the Profibus-PA Electronics Module Assembly
Use the following procedure to remove the Profibus-PA electronics
module assembly:
NOTE
Part of the electronics are sealed in a moisture-proof plastic enclosure
referred to as the electronics module. The module is a non-repairable unit; if a
malfunction occurs the entire unit must be replaced.
1. Disconnect the power to the transmitter.
2. Remove the cover from the electronics side of the transmitter
housing. Do not remove any covers in explosive atmospheres when
the circuit is live.
3. Loosen the two screws that anchor the electronics module assembly
to the transmitter housing.
4. Firmly grasp the screws and assembly and pull it straight out of the
housing, taking care not to damage the interconnecting pins.
NOTE
Note the transmitter’s security switch position (ON or OFF). If the electronics
module is being replaced with a new one, ensure the security switch is set in
the same position (see “Security” on page 2-10).

module assembly.
1. Ensure that the transmitter security switch on the electronics module
assembly is in the same position as the one that is being replaced.
2. Carefully insert the electronics module assembly to mate the
interconnecting pins with the necessary receptacles on the
electronics board attached to the housing.
3. Tighten the two mounting screws.
4. Replace the cover. Tighten the cover

Rosemount Conformance to Specification
You can be confident that a Rosemount product not only meets our published
specifications, but most likely exceeds them. Our advanced manufacturing
techniques and use of Statistical Process Control provide specification
conformance to at least ± 3
improvement ensures that product design, reliability, and performance get better
every year.
For example, the Reference Accuracy distribution for the Model 3244MV
MultiVariable Temperature Transmitter with Profibus-PA is shown to the right. Our
Specification Limits are ± 0.10 °C, but, as the shaded area shows, approximately
68% of the units perform three times better than the limits. Therefore, it is very
likely that you will receive a device that performs much better than our published
specifications.
Conversely, a vendor who “grades” product without using Process Control, or who
is not committed to ± 3 performance, will ship a much higher percentage of units
that are barely within (or even outside of) advertised specification limits.

Sensor Lead Wire Resistance Effect
RTD Input
When using a 4-wire RTD, the effect of lead resistance is eliminated and has
no impact on accuracy. However, a 3-wire sensor will not fully cancel lead
resistance error because it cannot compensate for imbalances in resistance
between the lead wires. A 2-wire sensor will produce the largest error
because it directly adds the lead wire resistance to the sensor resistance. For
2- and 3-wire RTDs, an additional lead wire resistance error is induced with
ambient temperature variations. Table A-2 and the examples shown below
help quantify these errors.

4-wire RTD None (independent of lead wire resistance)
3-wire RTD ± 1.0 Ω in reading per ohm of unbalanced lead wire resistance
2-wire RTD 1.0 Ω in reading per ohm of lead wire resistance
(1) Unbalanced lead wire resistance = maximum imbalance between any two leads.
Examples of Approximate Basic Error Calculation:
Given:
• Total cable length = 150 m
• Unbalance of the lead wires @ 20 °C = 0.5
Ω
• Resistance/length (18 AWG Cu) = 0.025 Ω/m
• Temperature Coefficient (Cu) = 0.0039
Ω/Ω/ °C
• Approximate Pt 100 resistance variation with temperature = 0.39
Pt 100 3-wire RTD:
• Lead wire resistance seen by the transmitter = 0.5
Ω
• Basic error = 0.5 Ω/(0.39 Ω/ °C) = 1.3 °C
• Error due to an ambient temperature variation of ± 25 °C = ± 0.13 °C
Pt 100 2-wire RTD:
• Lead wire resistance seen by the transmitter =
150 m 2 wires 0.025
Ω/m = 7.5 Ω
• Basic error = 7.5 Ω/(0.39 Ω/°C) = 19.2 °C
• Error due to an ambient temperature variation of ± 25 °C = ± 1.9 °C

Ambient Temperature Effect
Transmitters may be installed in locations where the ambient temperature is
between –40 and 85 °C. Each transmitter is individually characterized over
this ambient temperature range at the factory in order to maintain excellent
accuracy performance in dynamic industrial environments. This special
manufacturing technique is accomplished through extreme hot and cold
temperature profiling with individual adjustment factors programmed into each
transmitter. Transmitters automatically adjust for component drift caused by
changing environmental conditions.

• Descriptor: 16 alphanumeric characters
• Message: 32 alphanumeric characters
Trim to Specific Rosemount RTD Calibration Schedule
(Transmitter-to-Sensor Matching) (option code C2)
Option code C2 allows you to order the transmitter trimmed to a specific
calibration schedule. This option requires that you order a Rosemount Series
65, 68, or 78 RTD sensor with a special calibration schedule. For information
on ordering sensors calibrated to specific calibration schedules, refer to the
Rosemount Sensors Product Data Sheets, publication number
00813-0100-2654 (Volume 1) or publication number 00813-0101-2654
(Volume 2).
September 2002
Five Point Calibration (option code C4)
Option code C4 specifies that the transmitter be calibrated and verified at
five-points: 0, 25, 50, 75, and 100% digital output points.
Trim to Special non-Standard Sensor (option code C7)
You may order the transmitter with option code C7 when connecting
non-standard sensors, adding a special sensor, or expanding input ranges on
a standard sensor. Refer to Table 7-1 on page 7-1 for a list of standard sensor
types.
A characterization schedule for any RTD can be entered using Callandar-Van
Dusen constants with a Profibus configuration tool. The constants can be
entered on site or at the factory. For information on ordering sensors matched
to the transmitter using Callandar-Van Dusen constants, refer to the
Rosemount Sensors Product Data Sheet 00813-0100-2654 (Volume 1) or
00813-0101-2654 (Volume 2).
When a non-standard sensor is used as the input to the transmitter, the
resistance versus temperature curve for a non-standard RTD, or the millivolt
versus temperature curve for a non-standard thermocouple, is stored in the
transmitter memory. This process is performed at the factory. The transmitter
must be configured for a “special” sensor calibration to access the special
curve, but you may use any standard input when the transmitter is configured
for a “standard” sensor.
