INSTALLATION
Evaluate the site selected for the Transmitter installation with respect to the process
system design specifications and Honeywell’s published performance characteristics
for your particular model.
Temperature extremes can affect display quality. The display can become unreadable
at temperature extremes; however, this is only a temporary condition. The display will
again be readable when temperatures return to within operable limits.
FEATURES AND OPTIONS
The STT750 is packaged in one major assembly: the Electronics Housing.
The elements in the Electronic Housing are connected to the process sensors,
measure the process variables, respond to setup commands and execute the software
and protocol for the different temperature measurement types. Figure 1 shows the
assemblies in the Electronics Housing with available options.
Figure 1 –Electronics Housing Components
The Transmitter measures process Temperature and outputs a signal proportional to
the measured process variable (PV), including 4 to 20mA.
An optional 3-button assembly is located under the nameplate and provides a user
interface and operation capability without opening the transmitter to set up and make
adjustments to the Transmitter.

WIRING CONNECTIONS AND POWER UP
Summary
The transmitter is designed to operate in a two-wire power/current loop with loop
resistance and power supply voltage within the HART and DE operating ranges
shown in Figure 7.
Figure 7 - STT750 HART/DE Transmitter Operating Ranges
Loop wiring is connected to the Transmitter by simply attaching the positive (+) and
negative (–) loop wires to the positive (+) and negative (–) terminals on the
Transmitter terminal block in the Electronics Housing shown in Figure 8.
Connect the Loop Power wiring shield to earth ground only at the power supply end.
Note that the Transmitter is not polarity-sensitive.

SmartLine Temperature Transmitter
10 Quick Start Installation Guide
Figure 8 - Transmitter 9-Screw Terminal Board and Grounding Screw
As shown in Figure 8, each transmitter has an internal terminal to connect it to earth
ground. Optionally, a ground terminal can be added to the outside of the Electronics
Housing. 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 terminal block can be installed in place of the non-lightning
terminal block for transmitters that will be installed 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.
Note: Terminal pin 9 is not used.
Wiring must comply with local codes, regulations and ordinances.
Grounding may be required to meet various approval body certification,
for example CE conformity. Refer to Appendix A of this document for details.
Note: Terminal #3 is for loop test
The Transmitter is designed to operate in a two-wire power/current loop with loop
resistance and power supply voltage within the operating range; se
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
and maximum loop resistance. Additional consideration is required when selecting
intrinsic safety barriers to ensure that they will supply at least minimum Transmitter
voltage, including the required 250 ohms of resistance (typically within the barriers)
needed for digital communications. See Figure 7.

Quick Start Installation Guide 11
Wiring Variations
The above procedures are used to connect power to a Transmitter. For loop wiring
and external wiring, detailed drawings are provided for Transmitter installation in
non-intrinsically safe areas and for intrinsically safe loops in hazardous area locations.
This procedure shows the steps for connecting power to the transmitter.
Wiring must comply with local codes, regulations and ordinances. Grounding
may be required to meet various approval body certification, for example CE
conformity. Refer to the STT750 SmartLine Transmitter User’s Manual
34-TT-25-13 for details.
Input Sensor Wiring
Connect the input sensors as shown in Figure below:
Figure 9 –STT750 Thermocouple, RTD, mV, Ohm and Volt Connections

EXPLOSION-PROOF CONDUIT SEAL
When installed as explosion proof in a Division 1 Hazardous Location, keep
covers tight while the Transmitter is energized. Disconnect power to the
Transmitter in the non-hazardous area prior to removing end caps for service.
When installed as non-incendive equipment in a Division 2 hazardous location,
disconnect power to the Transmitter in the non-hazardous area, or determine that
the location is non-hazardous before disconnecting or connecting the Transmitter
wires.
Transmitters installed as explosion proof in Class I, Division 1, Group A Hazardous
(classified) locations in accordance with ANSI/NFPA 70, the US National Electrical
Code, require a LISTED explosion proof seal to be installed in the conduit, within 18
inches (457.2 mm) of the Transmitter. Crouse-Hinds type EYS/EYD or EYSX/EYDX
are examples of LISTED explosion proof seals that meet this requirement.
Transmitters installed as explosion proof in Class I, Division 1, Group B, C or D
hazardous (classified) locations do not require that explosion proof seal be installed
in the conduit.

greater than 21.5mA while Down
Scale drives the loop to a value less
than 3.5mA.
You can change the failsafe
direction by moving the Failsafe
Jumper (top jumper) to the desired
position (UP or DOWN).
The bottom jumper sets the Write
Protect. The default setting is OFF
(Un-protected).
When set to the On (Protected)
position, Changed configuration
parameters cannot be written to the
transmitter.
When set to the OFF (Un-protected)
position, Changed configuration
parameters can be written to the
transmitter.
