Configuration Tools

Integral Three Button Configuration Option

Suitable for all electrical and environmental requirements, SmartLine offers the ability to configure the transmitter and display via two buttons on the display and optional three externally accessible buttons. The button compartment is isolated from other internal components and thus keeps the sensitive electronics environmentally sound.

Zero/span capabilities are also optionally available via these buttons with or without selection of a display option.

Handheld Configuration

SmartLine transmitters feature two-way communication and configuration capability between the operator and the transmitter. This is accomplished via Honeywell Versatilis, a field-rated, next-generation multiple communication configuration tool.

The Honeywell Versatilis Handheld is capable of field configuring HART Devices and can also be ordered for use in intrinsically safe environments.

All Honeywell transmitters are designed and tested for compliance with the offered communication protocols and are designed to operate with any properly validated hand-held configuration device.

Personal Computer Configuration

Field Device Manager (FDM) Software and FDM Express are also available for managing HART device configurations.

Diagnostics

SmartLine transmitters all offer digitally accessible diagnostics which aid in providing advanced warning of possible failure events minimizing unplanned shutdowns, providing lower overall operational costs

System Integration ‘

o All SmartLine products meet the most current published standards for HART.

Modular Design

To help contain maintenance and inventory costs, all STT750 transmitters are modular in design supporting the user’s ability to replace temperature boards, add indicators or change electronic modules without affecting overall performance or approval body certifications.

Each temperature board is uniquely characterized to provide in-tolerance performance over a wide range of application variations in temperature and due to the Honeywell advanced interface, electronic modules may be swapped with any electronics module without losing in-tolerance performance characteristics

Modular Features

o Replace temperature board, terminal board, or lightning protection*

o Replace electronics or communication modules*

o Add or remove integral indicators*

o Add or remove external configuration buttons

* Field replaceable in all electrical environments (including IS) except flameproof without violating agency approvals. With no performance effects, Honeywell’s unique modularity results in lower inventory needs and lower overall operating costs.
