General
The smart positioner accurately controls valve stroke in response to an input signal of 4~20mA from
the controller. Built-in micro-processor optimizes the positioner’s performance and provides unique
functions such as Auto-Calibration, PD Control, and HART Protocol Communications.

Main Features and Functions

➢ When Input signal fails, Positioner keeps the current position of the valve stroke without any
additional device. (Fail Freeze option)
➢ The LCD can be checked and the buttons can be operated without opening the cover which
allows use of various functions of the positioner such as parameter adjustment in explosive gas
atmosphere.
➢ User will easily understand the method of using 4 buttons because it work same in all mode of
firmware interfaces.
➢ Positioner operates normally even there are sudden changes in supply pressure and / or high
vibration environment.
➢ The method of Auto Calibration is very simple.
➢ As an advantage of having very low air consumption, It could greatly reduce operating costs in
large-scale plants.
➢ It is compatible with most of controllers.
➢ Variable orifice can be used even to minimize the hunting occurrence and optimize operating
conditions.
➢ Various information about positioner can be processed by HART communication(Option)
➢ Valve system becomes more stable by outputting analog feedback signal.
➢ Different valve characteristics can be adjusted – Linear, Quick Open, Equal Percentage, and
User Set which user can make 5 or 18 points characterizations.
➢ Tight Shut – Close and Shut - Open can be set.
➢ PD parameters can be adjusted in the field without any additional communicator.
➢ Split range 4~12mA or 12~20mA can be set.
➢ Operating temperature for positioners is -30 ~ 80℃ (Please check certified explosion proof
temperature)
➢ Hand calibration function can set Zero point or End point manually.
➢ It has IP66 protection grade.
➢ Polyester powder coating resists the corrosion process.
➢ Maintenance of the positioner is easy because of modularized inner structure.
