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.
Mounting the Transmitter
Transmitter models, except flush mounts and those with integral flanges, can be
attached to a two-inch (50 millimeter) vertical or horizontal pipe using Honeywell’s
optional angle or flat mounting bracket; alternately you can use your own bracket.
Flush-mount models are attached directly to a process pipe or tank by a one-inch weld
nipple. Models with integral flanges are supported by the flange connection.
Typical Bracket mounted and Flange Mounted Installations
Bracket Mounting
• Optional mounting bracket, see Figure 2
• Existing mounting bracket, see Figure 3
• Rotate the transmitter housing, see Figure 4
Level a transmitter with small absolute or differential pressure spans, see Figure 5
Optional Mounting Bracket
Position the bracket on a 2-inch (50.8mm) and install “U” bolt around pipe and
through holes in bracket. Secure with nuts and lock washers provided.
Figure 2 Example - Angle mounting bracket secured to horizontal or vertical pipe.
Figure 2: Angle Mounting Bracket
Quick Start Installation Guide 1
Existing Mounting Bracket
Align appropriate mounting holes in transmitter with holes in bracket and secure with
bolts and washers provided.
Note: If the meter body is hexagonal, you must use the additional bracket supplied. If
meter body is round, discard the bracket.

Then….
Use alternate mounting holes in end of
heads.
Use smaller “U” bolt provided to attach
meter body to bracket. See Figure 3.
Rotating Transmitter Housing
Loosen set screw on outside neck of transmitter one full turn. Rotate Transmitter housing
in maximum of 180 degree increment in left or right direction from center to position you
require and tighten set screw (1.46 to 1.68Nm/13 to 15lb-in).
Figure 4 Example – Rotating Transmitter Housing.
Figure 4: Rotating Transmitter Housing
Figure 3: LGP and LAP models
Leveling Transmitters with Small Absolute or Differential Pressure Spans
Mounting position of these transmitters is critical due to the smaller transmitter spans.
To minimize these positional effects on calibration (zero shift), take the appropriate
mounting precautions that follow for the given transmitter model.
See Figure 5 for suggestions on how to level the transmitter using a spirit balance.
To perform a Zero Trim after leveling, refer to Trim the Transmitter on page 4.
Figure 5: Using level to mount transmitter
For model STA840, STA822, STA740 or STA722 transmitters, you must ensure that
the transmitter is vertical when mounting it. You do this by leveling the transmitter
side-to-side and front-to-back.
Mount transmitter vertically to assure best accuracy. Position the spirit balance on the
pressure connection surface of AP body.
Flange Mounting
To mount a flange mounted transmitter model, bolt the transmitter’s flange to the flange
pipe on the wall of the tank.
On insulated tanks, remove enough insulation to accommodate the flange extension.
It is the End User’s responsibility to provide a flange gasket and mounting hardware that
are suitable for the transmitter’s service condition.
To prevent degradation of performance in Flush-Mounted Flanged Transm itters, exercis e
care to ensure that the internal diameter of the flange gasket does not obstruct the
sensing diaphragm.
To prevent degradation of performance in Extended Mount Flanged Transmitters, ensure
that there is sufficient clearance in front of the sensing diaphragm body.

Flush Mounting
To mount a flush mounted transmitter model, cut a hole for a 1-inch standard pipe in the
tank or pipe where the transmitter is to be mounted. See Figure 7.
Weld the 1-inch mounting sleeve to the wall of the tank or to the hole cut on the pipe.
Insert the meter body of the transmitter into the mounting sleeve and secure with the
locking bolt. Tighten the bolt to a torque of 6.4Nm ±0.30Nm [4.7ft.-lbs. ±0.2ft.-lbs.]
Once the transmitter is mounted, the transmitter housing can be rotated to the desired
position. See Figure 7.
Figure 7: Flush Mounting
Remote Seal Mounting
Mount the transmitter at a remote distance determined by length of capillary tubing.
Note: The combination of tank vacuum and high pressure capillary head effect should
not exceed 9psi (300mm Hg) absolute.
On insulated tanks, remove enough insulation to accommodate the mounting sleeve.
Figure 8 Example – Typical Remote Seal Transmitter installation.
Note: For Sanitary 3-A installations, only mount the transmitter outside of the NonProduct Contact area where incidental contact with the process material is unlikely,
use a minimum capillary length of 1.5m (5ft.)

Summary
The transmitter is designed to operate in a two-wire power/current loop with loop resistance
and power supply voltage within the operating range shown in Figure 10.
Loop wiring is connected to the transmitter by simply attaching the positive (+) and
negative (–) loop wires to the positive (+) and negative (–) SIGNAL screw terminals on the
terminal block in the transmitter’s electronics housing shown in Figure 11.
Each transmitter includes an internal terminal to connect it to earth ground. Also, a ground
terminal can be optionally added to the outside of the electronics housing. While it is not
necessary to ground the transmitter for proper operation, doing so tends to minimize the
possible effects of noise on the output signal and affords protect ion aga inst lightn ing 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 an area that is highly susceptible to lightning
strikes.
Figure 10: Two-wire power/current loop
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 in f o r p r ot ect ion explosion proof in Class I, Division 1 do not need
an explosion proof seal in ac c o r dance with ANSI/ NF PA 70, the US National Elect rical
Code. A LISTED explosion proof seal t o be installed in the conduit, wit h in 18 in ch es
(457.2mm) of the Transmitt er w h en 3/4" co n d u it is u sed .
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.

See Figure 11, above, for parts locations.
Housing
Feed loop power leads through one end of the conduit entrances on
either side of the Electronics Housing. The Transmitter accepts up to 16
AWG wire.
Plug the unused conduit entrance as specified in Table 1.
Connect the positive loop power lead to the positive (+) terminal and the
negative loop power lead to the negative (-) terminal. Note that the
Transmitter is not polarity-sensitive.
Replace the end cap, and secure it in place using a 1.5mm hex wrench.

Note: The right hand terminal is for loop test and is not applicable for the Fieldbus
option.
Wiring Variations
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 SmartLine Transmitter User’s Manual, Documents # 34-
ST-25-35 (ST 800) or 34-ST-25-44 (ST 700) for details.
Trim the Transmitter
Procedure to Trim the Transmitter
For a transmitter with a small differential pressure span, you must ensure that the
transmitter is vertical when mounting it. You do this by leveling the transmitter side-to-
side and front-to-back. See Figure 5 for suggestions on how to level the transmitter
using a spirit balance. You must also zero the transmitter by following the steps in
this table.

the transmitter. For DE transmitter use SFC, SCT, or MCT. For
Hart, use MCT or other Hart Communicator with applicable
Honeywell DD's. For Fieldbus, use NI FBUS tools with
applicable Honeywell DD's.
While reading the transmitter’s output on a communication tool
or a voltmeter, position the transmitter so the output reading is at

PRESENT
Non-Incendive Equipment:
WARNING: DO NOT OPEN WHEN AN EXPLOSIVE ATMOSPHERE MAYBE
PRESENT
WARNING: FOR CONNECTION IN AMBIENTS ABOVE 60oC USE WIRE RATED
105oC
5. Conditions of Use for Ex Equipment, “Hazardous Location Equipment” or
“Schedule of Limitations”:
Painted surface of the ST700/ST800 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.
Flame-proof Installations: The transmitter can installed in the boundary wall
between an area of EPL Ga/ Class I Zone 0/ Category 1 and the less hazardous
area, EPL Gb/ Class I Zone 1/ Category 2. In this configuration, the process
connection is installed in EPL Ga/ Class I Zone 0/ Category 1, while the transmitter
housing is located in EPL Gb/ Class I Zone 1/ Category 2.
The applicable temperature class, ambient temperature range and maximum
process temperature of the equipment is as follows;
5. Continued
PROCESS TEMPERA TURE VS AMBIENT TEMPERATURE
Consult the manufacturer for dimensional information on the flameproof
joints for repair.
The transmitter can be installed in the boundary wall between an area of
Category 1 and the less hazardous area, Category 2. In this configuration,
the process connection is installed in Category 1 while the transmitter
housing is installed in Category 2.
Intrinsically Safe: Must be installed per drawing 50049892
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.
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.
