YT-3400 Smart ValvePositioner accurately controls valve stroke, according to input signal of 4~20mA being delivered from controller.Auto calibrationPID controlHART comunicationAuto/Manual switchFeedback signal4 buttons for local controlLCD displayLimit switchProduct DescriptionGeneralThe smart positioner accurately controls valve stroke in response to an input signal of 4~20mA fromthe controller. Built-in micro-processor optimizes the positioner’s performance and provides uniquefunctions such as Auto-Calibration, PID Control, and HART Protocol Communications.Main Features and Functions➢ The LCD can be checked and the buttons can be operated without opening the cover whichallows use of various functions of the positioner such as parameter adjustment in explosive gasatmosphere. User will easily understand the method of using 4 buttons because it work same inall mode of firmware interfaces.➢ When unexpected situation like momentary blackout happens, our positioner boot-time only take0.5 second and this can minimize the travel of valve which consequentially increase the safety ofsystem.➢ Positioner operates normally even there are sudden changes in supply pressure and / or highvibration environment.➢ The method of Auto Calibration is very simple.➢ As an advantage of having very low air consumption, It could greatly reduce operating costs inlarge-scale plants.➢ It is compatible with most of controllers.➢ Variable orifice can be used even to minimize the hunting occurrence and optimize operatingconditions.➢ 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, andUser Set which user can make 5 or 18 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 positioneror valve without any signal.➢ Split range 4~12mA or 12~20mA can be set.➢ Operating temperature for positioners is -30 ~ 85℃ or -40 ~ 85℃ (Please check certifiedexplosion proof ambient temperature)➢ Hand calibration function can set Zero point or End point manually.➢ It has Type 4, 4X(CSA), IP66 protection grade.➢ Polyester powder coating resists the corrosion process. (except YT-3450).➢ Maintenance of the positioner is easy because of modularized inner structure.➢ SIL2 certified.(For more information, see SIL Safety Instruction on homepage)
