About This Manual
This manual is a detailed how to reference for installing, piping, wiring, configuring, starting up,
operating, maintaining, calibrating, and servicing Honeywell’s family of ST 700 SmartLine
Pressure Transmitters. Users who have a Honeywell ST 700 SmartLine Pressure Transmitter
configured for HART protocol or Honeywell’s Digitally Enhanced (DE) are referred to the ST
700 Series HART/DE Option User’s Manual, document number 34-ST-25-47. Users who have a
Honeywell ST 700 SmartLine Pressure Transmitter configured for Fieldbus operation are referred
to the ST 700 Series Fieldbus Option User’s Manual, document number (34-ST-25-48).
The configuration of your Transmitter depends on the mode of operation and the options selected
for it with respect to operating controls, displays and mechanical installation. This manual
provides detailed procedures to assist first-time users, and it further includes keystroke
summaries, where appropriate, as quick reference or refreshers for experienced personnel.
To digitally integrate a Transmitter with one of the following systems:
•For the Experion PKS, you will need to supplement the information in this document with the
data and procedures in the Experion Knowledge Builder.
•For Honeywell’s TotalPlant Solutions (TPS), you will need to supplement the information in
this document with the data in the PM/APM SmartLine Transmitter Integration Manual,
which is supplied with the TDC 3000 book set. (TPS is the evolution of the TDC 3000).
