INTRODUCTION
The
FY303 is a Profibus PA valve positioner for Single (spring return) or Double acting Linear
motion type control valves e. g. Globe, Gate, Diaphragm, Pinch or Clamp and Rotary motion type
control valves e. g. Ball, Butterfly or Plug with pneumatic type actuators e. g. Diaphragm, Piston,
Vane, or Bellows. It is based on a field-proven piezo flapper and non-contacting Hall-effect position
sensor that provides reliable operation and high performance. The digital technology used in the
FY303 enabled the choice of several types of flow characterizations, an easy interface between the
field and the control room and several interesting features that considerably reduce the installation,
operating and maintenance costs.
The
FY303 is part of Smar's complete 303 line of Profibus PA devices.
Some of the advantages of bi-directional digital communications are known from existing smart
transmitter protocols: Higher accuracy, multi-variable access, remote configuration and diagnostics,
and multi-dropping of several devices on a single pair of wires.
The system controls variable sampling, algorithm execution and communication so as to optimize
the usage of the network, not loosing time. Thus, high closed loop performance is achieved.
Using Profibus technology, with its capability to interconnect several devices, very large control
schemes can be constructed. In order too be user friendly the function block concept was
introduced.
The need for implementation of Fieldbus in small as well as large systems was considered when
developing the entire 303 line of Profibus-PA devices. They have common features and can be
configured locally using a magnetic tool, eliminating the need for a configuration tool or console in
many basic applications.
Get the best result of the
FY303 by carefully reading these instructions.
NOTE
In case of using Simatic PDM as the configuration and parameterization tool, Smar
recommends that the user does not apply the option "Download to Device". This function
can improperly configure the field device. Smar recommends that user make the use of
the option "Download to PG / PC" and then selecting the Device Menu, use the menus of
the transducer, function and display blocks acting specifically, according to each menu
and method for reading and writing.
WARNING
Throughout the operation of the positioner, including self-setup, do not touch the moving parts of
valve/actuator/positioner assembly as they may unexpectedly move automatically. Make sure to disconnect
supply air before touching any moving parts.
