INTRODUCTION
The
FY301 is a smart 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
FY301 enabled the choice of
several types of flow characterizations, an easy interface between the field and the control room, not to
mention several interesting features that considerably reduce the installation, operation and
maintenance costs.
The
FY301 , besides the normal functions offered by other smart positioners, offers the following
functions:
*
Table - on top of the regular valve characterization curves like linear, equal percentage and quick
opening (hyperbolic), the valve set point signal may be custom linearized according to a 16 point table,
making it possible to achieve flow characterization being a combination of linear and equal percentage
etc.
*
Local Adjustment - not only for travel adjustment, but also flow characterization, tuning, operation
mode, indication, set point and PID parameters... as well.
*
Password - three levels for different functions.
*
Operation Counter - shows the number of changes in each function.
*
Auto Setup - automatic calibration of valve travel.
* Diagnostic – permanently valve monitoring condition for preventive maintenance.
Get the best results of the
FY301 by carefully reading the instructions of this manual.
WARNING
Throughout the operation of the positioner, including auto setup, do not touch the moving parts of the
valve/actuator/positioner `set as they may unexpectedly move automatically. Make sure to disconnect
air supply before touching any moving parts.
