Ø The enclosure of Econ
®
series 3300 contains aluminum, which is considered to constitute a
potential risk of ignition when subjected to impact or friction.
Ø Care must be used during installation in locating this equipment to prevent impact or friction
Ø Some of the enclosure parts are made of non-metallic materials. To prevent the risk of
Ø Electrostatic sparking, clean the enclosure only with a damp cloth.
Ø The product must be installed in such a manner as to minimize the risk of impact or friction with
other metal surfaces.

2 Product Description
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
Ø LCD display enables users to monitor the positioner status.
Ø Positioner operates normally during sudden changes in supply pressure and / or high vibration
environment.
Ø 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.
Ø Variable orifices can be used to minimize the hunting occurrence and optimize operating
conditions.
Ø Valve system feedback is greatly improved by the accuracy and fast response of the series 3300.
Ø Different valve characteristics can be adjusted – Linear, Quick Open, Equal Percentage, and
