2.1 General
Econ
®
series 3300 Smart Valve Positioner accurately controls valve stroke in response to an
input signal of 4-20mA from a process controller. An built-in micro-processor optimizes the
positioner’s performance and provides unique functions such as Auto-Calibration, PID
Controlled , Alarms, and HART
®
Protocol Communications.
2.2 Main Features and Functions
LCD display enables users to monitor the positioner status.
Positioner operates normally during sudden changes in supply pressure and / or high
vibration environment.
Low air consumption level and low voltage use (8.5 V) yield to lower plant operating
costs. The series 3300 is compatible with most of controllers.
Variable orifices can be used to minimize the hunting occurrence and optimize operating
conditions.
Valve system feedback is greatly improved by the accuracy and fast response of the
series 3300.
Different valve characteristics can be adjusted – Linear, Quick Open, Equal Percentage,
and Custom which user can make 16 points characterizations.
Tight Shut – Close and Shut - Open can be set.
PID parameters can be adjusted in the field without any additional communicator.
A/M switch can be used to direct supply air to the actuator or to manually operate the
positioner or valve.
Split range 4-12mA or 12-20mA can be set.
Operating temperature is -30 ~ 85’C.
Manual Operation allows the user to operate the valve manually.
