Functional Characteristics
The transmitter measures process temperature and outputs a signal proportional to the measured
process variable (PV). Available output communication protocols include 4 to 20mA, Honeywell
Digitally Enhanced (DE) and HART protocols.
In addition, a Honeywell Multi-Communication (MC) Toolkit (not supplied with the transmitter) can
facilitate setup and adjustment procedures in the case of HART and DE. Certain adjustments can be
made through an Experion Station or a Universal Station if the transmitter is digitally integrated with
Honeywell’s Experion or TPS/TDC 3000 control system for HART and DE transmitte rs.
STT700 SmartLine Transmitter Nameplate
The transmitter nameplate mounted on the side of the transmitter (see Figure 3) lists its model
number, physical configuration, electronics options, accessories, certifications, and manufacturing
specialties.

2. Application Design
Overview
This section discusses the considerations involved with deploying a Honeywell STT700 SmartLine
Temperature Transmitter in a process system. The following areas are covered:
• Safety
• Input and output data
• Reliability
• Environm enta l limits
• Installation considerations
• Operation and maintenance
• Repair and replacement
Safety
Accuracy
The STT700 SmartLine Temperature Transmitter accurately measures the temperature of a process
and reports the measurement to a receiving device like a controller I/O module. Refer to STT700
Specification, 34-TT-03-19, for complete accuracy specifications.
Diagnostic Messages
The transmitter standard diagnostics are reported in the two basic categories: critical and non-critical
faults. Problems detected as critical diagnostics drive the analog output to the programmed burnout
level for HART and DE. Tables 3 and 4, below, list the diagnostics and how faults are handled by the
STT700 transmitter. Refer to the Troubleshooting section for further details.
Table 3 show specific diagnostics to the transmitter, exclusive of those associated with HART and
DE protocols. HART and DE diagnostic messages are listed and described in the STT700 SmartLine
Temperature Transmitte r HART/DE Option User Manual, document number 34-TT-25-18.
See Safety Integrity Level (SIL)
STT700 is intended to achieve sufficient integrity against systematic errors by the manufacturer’s
design. A Safety Instrumented Function (SIF) designed with this product must not be used at a SIL
level higher than the statement, without “prior use” justification by the end user or diverse technology
redundancy in the design. Refer to the STT700 Sa fety Manual, 34-TT-25-20, for additional
information. The DE variant of STT700 is not SIL certified.

Mounting and Dimensions
DIN Rail Mounting
If the STT700 is to be installed on DIN rail option then the main considerations are electrical
connections and mechanical fixing. Electrical connections are identical to the bench test instructions
except that thermocouple wire is likely to be used with thermocouples. Mechanical fixing of the
module is by means of the snap-in DIN rail clips which are screwed to the bottom lugs of the module.
Figure 5 - DIN Rail Mounting
The DIN rail needs to be connected to Earth Ground per Section 3.4 below. It is generally required
by regional wiring, safety and installation codes that these units be mounted in a suitable enclosure
such as a metal cabinet or box which is locally connected to Earth Ground.

For non-North American spring loading as shown in Figure 9, simply include the springs under the 33
mm pitch mounting screws, pass the screws through the module and sensor mounting plate and snap
in the retaining circlip to the screws to hold the assembly together. Guide the sensor assembly through
the housing sensor entry and screw down the 33 mm screws until the limit is reached as the sensor
presses against the bottom of thermowell.
For wall or 2'' pipe mounting, the temperature sensor can be remote from the STT700 field mount
housing or integral to the housing. For remote installations, the sensor wiring should be run in
shielded, twisted pair wiring and connected via one of the housing wiring entries.
For explosion proof/flam eproof ins ta llat ions, ensure that the cable entries are fitted w ith flameproof
adaptors and that the wiring grade complies with local standards.

Wiring a transmitter
Please note the display module must be removed from support bracket to access the power
connections for HART or DE.
Loop Power Overview
The transmitter is designed to operate in a two-wire power/current loop with loop resistance and
power supply voltage within the HART or DE operating range shown in Figure 10 and Figure 11.
Figure 18 – STT700 with HART Transmitter Operating Ranges
Figure 19– STT700 with DE Transmitter Operating Ranges
Page 20 STT700 Temperature Transmitter User’s Manual Revision 6
Loop wiring is connected to the transmitter by simply attaching the positive (+) and negative (–) loop
wires to the positive (+) and negative (–) termina ls on the transmitter module terminal block. Route
the wires through the pre-moded channels on top of the terminal module. Connect the loop power
wiring shield to Earth Ground only at the power supply end.
Note that the STT700 transmitter features SmartLine’s Universal terminal wiring capability and thus
is not polarity-sensitive.
With the single input HART transmitter, four (4) terminal screws will be available on the top of the
module. When either the dual-input HART or the single input DE is suppli ed, five (5) termination
screws will be included.
Figure 20 –STT700 module terminal connections
This transmitter uses the two m o un ting screws to connec t it to Earth Ground. Grounding the
transmitter for proper operation is required, as doing so tends to minimize the possible effects of noise
on the output signal and affords protection against lightning and static discharge. An optional
lightning protection module is available for use in areas that are highly susceptible to lightning
strikes. As noted above, the loop power wiring shield should only be connected to Earth Ground at
the power supply end.
Wiring must comply with local codes, regulations and ordinances.
The current output signal will operate a floating or ground system.
If the signal appears noisy or erratic, it is recommended to ground the loop at the
negative terminal of the power supply.
Shielding should only be connected to ground at one point to avoid ground loops.
Revision 6 STT700 Temperature Transmitter User’s Manual Page 21
For HART and DE, the transmitter is designed to operate in a two-wire power/current loop with loop
resistance and power supply voltage within the operating range; see Figure 18 and Figure 19. With an
optional remote meter, the voltage drop for this must be added to the basic power supply voltage
requirements, to determine the required transmitter voltage (V

The positive and negative loop wires are connected to the positive (+) and negative (–) terminals on
the STT700.
Barriers can be installed per Honeywell’s instructions for transmitters to be used in intrinsically safe
applications.
Note: Problems detected as non-critical diagnostics may affect performance without driving the
analog output to the programmed burnout level (for HART only). For DE, the burnout direction
needs to be selected in the hardware and this will be detected at power on time.
Digital System Integration Information
DE transmitters that are to be digitally integrated to Honeywell’s Total Plant Solution (TPS) system
will be connected to the temperature transmitter Interface Module in the Process Manager, Advanced
Process Manager or High Performance Process Manager through a Field Termination Assembly.
Details about the TPS system connections are given in the PM/APM SmartLine Transmitter
Integration Manual, PM12-410, which is part of the TDC 3000
X
system bookset.
When digitally integrating a transmitter in an Allen Bradley Programmable Logic Controller (PLC)
process system, the same Field Terminal Assembly (FTA) and wiring procedures used with
Honeywell’s TPS system are also used with the Allen-Bradley 1771 and 1746 platforms.
Wiring Variations
The above procedures are used to connect power to a transmitter. For loop wiring, sensor wiring and
external wiring, detailed drawings are provided for transmitter installat ion in no n -intrinsically safe
areas and for intrinsically safe loops in hazardous area locations.
If you are using the transmitter with Honeywel l’ s TPS sy stem , see PM/APM SmartLine Transmitter
Integration Manual, PM12-410, which is part of the TDC 3000
X
system bookset.

Grounding and Lightning Protection
Connect a wire from the mounting screws to Earth Ground to make the protection effective. Use size
14 AWG or 2.0mm
For ungrounded thermocouple, mV, RTD or ohm inputs, connect the input wiring shield(s) to the
same Earth Ground connection.
For grounded thermocouple inputs, connect the internal ground connection shown in Figure 12 to the
same Earth Ground as used by the thermocouple. For direct head mount housings, the ground
terminal may not exist and another means of direct ground connection will need to be devised. For
proper protection, the green ground wire must be securely connected to a local ground in as direct a
path as possible. As noted above, the loop power wiring shield should only be connected to Earth
Ground at the power supply end.
The tightening torque to be applied on the wire termination screws are to be
between 0.34 Nm (3 in-lbf) min to 0.56 Nm (5 in-lbf) max.
Shielded twisted pair cable gauge 18AWG-22AWG for the sensor connections and

3.5.5.1. Sensor Wiring Best Practice Recommendation:
• Sensor cable should be a shielded cable and the shield should be connected to protection earth
at the transmitter end. Refer Figure 12, STT700 module terminal connections for details of
grounding screw.
• Sensor lines should be isolated from high voltage lines and should not be routed in parallel
with high voltage lines.
• Sensor wires are designed to be routed through a controlled EMC environment. Possible
sources of surges shall be avoided.
• For any queries contact Honeywell Technical support team.
Revision 6 STT700 Temperature Transmitter User’s Manual Page 23
Connect the input sensors as shown in figures below for RTD, thermocouple, mV and ohm
connections.
Figure 21 – HART/DE Input Wiring Diagram for single sensor connection
The single sensor connections can also be used on a dual input transmitter when a second input is not
required. In this case, it is recommended that the second input be configured to None in the software.
In case of RTD type being configured for 4-wire, the configuration for single input is automatically
done.

Lightning Protector
The lightning protection device is designed to give the STT700 temperature transmitter maximum
protection against surges such as those generated by lightning strikes. It mounts on the top of the
STT700 transmitter module, providing easy field wiring and also protection for the EU meter if used.
The compact mounting allows the use of a variety of housings including the Honeywell explosion
proof field mount housing.
The device can be used in both intrinsic safety and flame/explosion proof applications.
Figure 23 – STT700 with Lightning Protector Dimensions
Revision 6 STT700 Temperature Transmitter User’s Manual Page 25
3.5.6.1. Installation
• If an EU meter is used, remove the shunt on the Lightning Protector. In all other cases, the
shunt must be present.
• Remove the cover/cap of the housing (if applicable). The device fits on the top of the
transmitter module terminal block and the transmitter output screws (+ and -) fix
mechanically the device.
• Attach the grounding wire to the ground screw in the housing. Connect a wire from the
transmitter enclosure to local Earth Ground. Use size 14 AWG or 2.0mm2 bare or green
covered wire.
• If an EU meter is used, wire according to Figure 24.
• Connect the 4 – 20mA loop to the + and – terminal screws of the surge protection and close
the cap of the housing.
Figure 24 – Installation without EU Meter

Revision 6 STT700 Temperature Transmitter User’s Manual Page 27
3.5.6.2. Maintenance
The unit is designed to give a long service life under normal industrial conditions. Howev er, if
exposed to a large number of high energy transients beyond the capability of the unit, the lig htning
protector may fail. The unit has been designed so that, under excessive surge conditions (more than
10 KA), the lightning protector should fail, thus protecting the transmitter.
If the unit has failed, it can be replaced in the field – the process for removal in the reserve of that
for installing the unit.
If a replacement is not immediately available, part number 50133588-501-501, it is possible to
bypass the unit by wiring directly to the transmitter; however, it should be remembered that, in this
case, the transmitter will be unprotected from surges.

4. Startup
Overview
This section identifies typical startup tasks the STT700 temperature transm it ter an d includes the
procedure for running an optional analog output check.
Startup Tasks
After completing the installation and configuration tasks for a transmitter, you are ready to startup the
process loop. Startup usually includes:
• Setting initial resistance, based on actual temperature (RTD sensor types only)
• Reading inputs and outputs
• Applying process inputs to the tra ns mitter.
You can also run an optional output check to wring out an analog loop and check out individual
Process Variable (PV) outputs in Digitally Enhanced (DE) mode before startup.
The actual steps in a startup procedure vary based on the type of transmitter and the measurement
application. In general, the procedures in this section are based on using Honeywell MC Toolkit, with
a HART or DE variant, to check the transmitter input and output under static process conditions, and
make adjustments as required initiating full operation with the running process.
Output Check Procedures
The Output Check comprises the following procedures:
• The Loop Test procedure checks for continuity and the condition of components in the output
current loop.
• The Trim DAC Current procedure calibrates the output of the Digital-to-Analog converter for
minimum (0%) and maximum (100%) values of 4 mA and 20 mA, respectively. This
procedure is used for transmitters operating online in analog mode to ensure proper operation
with associated circuit components (for example, wiring, power supply, control equipment).
Precision test equipment (an ammeter or a voltmeter in parallel with precision resistor) is
required for the Trim DAC Current procedure.
• The Apply Values procedure uses actual Process Variable (PV) input levels for calibrating
the range of a transmitter. The PV is carefully adjusted to stable minimum and maximum
levels, and the Lower Range Limit Value (LRV) and Upper Range Limit Value (URV) are
then set by commands from the MC Toolkit.
The transmitter does not measure the given PV input or update the PV output
while it operates in the Output mode.
Revision 6 STT700 Temperature Transmitter User’s Manual Page 29
Constant Current Source Mode Procedure
Please note the display module must be removed from support bracket to access the power
connections for HART or DE connections in Figure 27. Refer to Uninstalling/Installing Standard
Display for external wiring on page 16
Figure 27 – Current Loop Test Connections
1. Refer to Figure 27 for test connections. Verify the integrity of electrical components in the output
current loop. Please note that the temperature transmitter is shown as STT700 device only for
ease of connections understanding.
2. Establish communication with the transmitter. For these procedures, the v alues of com ponents in
the current loop are not critical if they support reliable communication between the transmitter
and the MC Toolkit.
3. On the MC Toolkit, display the Output Calibration box.
4. In the Output Calibration box, select the Loop Test button; the LOOP TEST box will be
displayed.
5. Select the desired constant-level Output: 0 %, 100 %, or Other (any between 0 % - 100 %).
6. Select the Set button. A box will be displayed asking Are you sure you want to place the
transmitter in output mode?
Page 30 STT700 Temperature Transmitter User’s Manual Revision 6
With t he transmitter in Analog mode, you can observe the output on an
externally-connected meter or on a local meter.
7. Select the Yes button. Observe the output current at the percentage you selected in Step 5.
8. To view the monitor display, navigate back from the LOOP TEST display, and select the
MONITOR display. A Confirm popup will be displayed.
9. Select Yes to continue. This concludes the Startup procedure.
Revision 6 STT700 Temperature Transmitter User’s Manual Page 31
5. Operation
Overview
The Operations section describes the internal operation of the STT700 transmitter and the operations
of the Smart Field Communicator and the HART communicator with the STT700. If an EU Meter is
installed, see the Engineering Unit Meter User Guide 34-ST-25-18 for additional information on
operations.
This transmitter is powered via the 2-wire, 4-20 mA signal connected to the + and - terminals on the
output side of the module.
Configuration Tools
Smart Field Communicator (SFC) for DE Models
As previously indicated, the SFC communicates by connecting across the 4-20 mA wiring. DE
communication is by 16 mA pulses which disturb the 4-20 mA output signal. When in analog mode,
ensure that receiving instruments are not on automatic control. The SFC does not feed 16 mA pulses
into the loop but instead merely uses the power on the 4-20 mA wires and switches it through a field
effect transistor output switch. The SFC alw ay s acts as a host and the transmitter as a device. When
the transmitter is operating in the digital DE mode, there is no wake-up pulse required and the SFC
communication does not disturb the PV signal. Consequently, there is no need to put the loop on
manual control when operating in the DE mode.
Supported Commands:
• Read/write ID (e.g. TID 250)
• Select a sensor type (e.g. Pt100)
• Enable/disable sensor break detection
• Set damping time (e.g. 0 second)
• Set LRV and URV
• Read URL (upper range limit), LRL (lower range limit) and span

• Select broadcast type 4 or 6 bytes (Digital DE only). 6 bytes broadcasts PV and transmitter
database while 4 bytes broadcasts PV only
• Enable/disable write protect
• Enable/disable latching. Latching means the alarm needs acknowledgment. Press "STATUS"
key to acknowledge the alarm. If latching is disabled, the transmitter will leave the alarm
mode as soon as the alarm cause disappears.
Page 32 STT700 Temperature Transmitter User’s Manual Revision 6
HART Communicator Model 375, 475 or MC Toolkit FDC for
HART 7 Models
Connect the HART communicator by attaching the leads in parallel with the input (24V) terminals of
the device. HART communication consists of a high frequency carrier superimposed onto the 4-20
mA signal. The HART transmitter transmits by modulating the 4-20 mA DC loop current with a 1
mA peak to peak (p-p) AC current signal.

6. Maintenance
Overview
Maintenance of this transmitter is limited to ensuring that connections, seals and mounting hardware
are tight and secure. There are no moving parts or adjustments, thus, the only reason to open the
housing (where supplied) is to inspect for corrosion or conductive dust entry which could later affect
reliable operation.
WARNING:
Preventive Maintenance Practices and Schedules
This SmartLine transmitter does not require any specific maintenance at regularly scheduled intervals.
Please take appropriate steps to avoid ESD damage when handling
The transmitter module itself should NEVER be opened.
Troubleshooting
Troubleshooting with SFC
Troubleshooting the STT700 DE transmitter loop is greatly simplified by connecting the SFC in the
termination area near the receiving instrum ent. A lso co nnect a digital volt meter (DVM), at the
termination area for the receiving instrument, to confirm a similar signal is coming from the field and
power is available on the two wires of the 4-20 mA loop. This isolates the problem to either field loop
or receiving instrument/power supply/wiring/safety barriers etc. If the original symptom was an
unstable input, it could be a loose connection on the receiving side. Assuming the above confirms a
field loop problem, the likely causes and actions are given below.
For any step the first action is to hook up the SFC to the transmitter and press "ID", then "STATUS".

7. Calibration
Recomme nda ti ons for transmitter Calibration
The STT700 SmartLine Temperature Transmitter does not require periodic calibration to m ain t ain
accuracy. Typically, calibration of a process-connected transmitter will degrade, rather than augment
the capability of a smart transmitter. For this reason, it is recommended that a transmitter be removed
from service before calibrat ion. Moreover, calibration must be accomplished in a controlled,
laboratory-type environment, using certified precision equipment.
Calibration Procedures
For a transmitter operating in analog mode, you must calibrate its output signal measurement range
using any compatible hand-held communicator..
One calibration option is to use the Honeywell MC Toolkit (MCT). Refer to the MC Toolkit User
Manual, MCT404, Document # 34-ST-25-50
Calibration information and procedures for a transmitter operating in the HART/DE mode are
provided in the STT700 Series HART/DE Option User’s manual, document number 34-TT-25-18,
Section on “Calibration.”

• Name and Address of the manufacturer
• Notified Body identification: DEKRA Quality B.V., Arnhem, the Netherlands
• For complete model number, see the Model Selection Guide for the particular model of
temperature transmitter.
• The serial number of the transmitter is located on the Housing data-plate. The first two
digits of the serial number identify the year (02) and the second two digits identify the week
of the year (23); for example, 0223xxxxxxxx indicates that the product was manufactured in
2002, in the 23rd week.
Apparatus Marked with Multiple Types of Protection
The user must determine the type of protection required for installation the equipment. The
user shall then check the box [�] adjacent to the type of protection used on the equipment
certification nameplate. Once a type of protection has been checked on the nameplate, the
equipment shall not then be reinstalled using any of the other certification types.
A.6 WARNINGS and Cautions:
Intrinsically Safe and Non-Incendive Equipment:
WARNING: SUBSTITUTION OF COMPONENTS MAY IMPAIR SUITABILITY FOR USE IN
HAZARDOUS LOCATIONS.
Explosion-Proof/ Flameproof:
WARNING: DO NOT OPEN WHEN AN EXPLOSIVE ATMOSPHERE MAY BE PRESENT
Non-Incendive Equipment:
WARNING: DO NOT OPEN WHEN AN EXPLOSIVE ATMOSPHERE MAYBE PRESENT
All Protective Measures:
WARNING: FOR CONNECTION IN AMBIENTS ABOVE 60oC USE WIRE RATED 105oC
Page 56 STT700 Temperature Transmitter User’s Manual Revision 6
A.6 Conditions of Use” for Ex Equipment”, Hazardous
Location Equipment or “Schedule of Limitations”:
The installer shall provide transient over-voltage protection external to the equipment such
that the voltage at the supply terminal of the equipment does not exceed 140% of the
voltage rating of the equipment.
Intrinsically Safe: Must be installed per drawing 50133855
Division 2: This equipment is suitable for use in a Class I, Division 2, Groups A, B, C, D; T4 or
Non-Hazardous Locations Only.
Transmitter only selection:
For ATEX Category 3 or Zone 2 Locations, the Transmitter must be installed within an
enclosure with a minimum degree of protection of IP54 in accordance with:
For US Installations: in a tool-secured enclosure which meets the requirements of
ANSI/ISA 60079-0 and ANSI/ISA 60079-15 and the ultimate application.
For ATEX or IECEx: in a tool-secured enclosure which meets the requirements of
EN/ IEC 60079-0 and EN/ IEC 60079-7 and the ultimate application.
Transmitter in Enclosure Selections:
Consult the manufacturer for dimensional information on the flameproof joints for repair.
Painted surface of the STT700 may store electrostatic charge and become a source of
ignition in applications with a low relative humidity less than approximately30% relative
humidity where the painted surface is relatively free of surface contamination such as dirt,
dust or oil. Cleaning of the painted surface should only be done with a damp cloth.
The enclosure is manufactured from low copper aluminum alloy. In rare cases, ignition
sources due to impact and friction sparks could occur. This shall be considered during
Installation, particularly if equipment is installed a Zone 0 location.
If a charge-generating mechanism is present, the exposed metallic part on the enclosure is
capable of storing a level of electrostatic that could become Incendive for IIC gases.
Therefore, the user/ installer shall implement precautions to prevent the buildup of
electrostatic charge, e.g. earthing the metallic part. This is particularly important if
equipment is installed a Zone 0 location.
For Installation of the NPT Plug or Adapter follow instructions as outlined in 34-XY-33-03.
