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.

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.

Overview

1. Function Description
2. Usage Features
3. Maintenance Features

The Honeywell SmartLine Pressure Transmitter ST 700 Basic is a robust and versatile device designed for measuring Differential Pressure (DP), Gauge Pressure (GP), and Absolute Pressure (AP) in various industrial applications. This quick start safety installation guide provides essential information for its setup and initial operation.

Function Description

The ST 700 Basic SmartLine Pressure Transmitter operates on a two-wire power/current loop, providing an analog output signal that corresponds to the measured pressure. It is designed to integrate seamlessly into existing process control systems, offering reliable and accurate pressure measurements. The transmitter can be configured for specific failsafe actions (up-scale or down-scale) and includes a write protect feature to prevent unauthorized changes to its configuration parameters. This ensures operational integrity and safety in critical applications. The device supports HART communication, allowing for remote configuration, diagnostics, and data acquisition using compatible communicators.

Usage Features

The transmitter offers flexible mounting options, including attachment to 2-inch (50 mm) vertical or horizontal pipes using optional angle or flat mounting brackets. For flush-mount models, direct attachment to a process pipe or tank via a 1-inch weld nipple is possible, while models with integral flanges are supported by their flange connection. The transmitter housing can be rotated up to 180 degrees in either direction from the center, allowing for optimal viewing and access after installation.

For applications with small absolute or differential pressure spans, precise leveling of the transmitter is crucial to minimize positional effects on calibration (zero shift). This can be achieved using a spirit balance, particularly for models like STA725 and STA72S, which require vertical mounting. The device's display module provides a standard two-line, six-character LCD for local viewing of process variables and menu navigation. The menu allows access to parameters such as PV display, pressure units, flow units, scaling (low and high), LRV/URV entry, zero correct, DAC zero trim, DAC span trim, loop test, and contrast adjustment. An extended menu can be enabled for more advanced configuration options.

Conduit entry plugs and adapters are provided to ensure environmental ingress protection and compliance with national and local code requirements for hazardous locations. The transmitter accepts up to 16 AWG wire for loop power leads and is not polarity-sensitive, simplifying wiring.

Maintenance Features

The ST 700 Basic SmartLine Pressure Transmitter is designed for ease of maintenance and long-term reliability. The quick start guide outlines procedures for trimming the transmitter, which is essential for maintaining accuracy, especially after initial installation or when dealing with small differential pressure spans. This involves connecting a tube between the high and low-pressure input connections to eliminate air current effects, applying 24Vdc power, and using a digital voltmeter or applicable communicator to monitor the PV output. The transmitter can then be positioned to achieve a near-zero output reading, and the mounting bolts are tightened. A Zero Correct function, accessible via the local display or communicator, allows for fine-tuning to correct any minor errors after mounting.

For explosion-proof installations, specific precautions are outlined, such as keeping covers tight while energized and disconnecting power before removing end caps for service. The guide emphasizes the importance of replacing temporary plastic dust protectors with suitable cable glands, adapters, or blanking plugs to maintain the specified environmental ingress protection and hazardous location certifications. The modular design, with accessible terminal blocks and jumpers, facilitates easy wiring and configuration adjustments. The device's robust construction and adherence to various certifications (including EMC, ATEX, PED, FM, CSA, INMETRO, IECEx, NEPSI, SAEX, and EAC) ensure its suitability for demanding industrial environments, minimizing the need for frequent maintenance and maximizing operational uptime.
