1. General Introduction
YTC YT-3300 Valve Positioner accurately controls valve stroke, according to input signal of 4~20mA being delivered from controller, features of typical specifications below :
Auto calibration: simple menu structure with options to auto calibrate all parameters or zero and end points only;
LCD display: alphanumeric digital display for process values and calibration;
Partial Stroke Test (PST): fully adjustable Partial Stroke Test. All functionality can be performed and selected locally, through push buttons, or remotely with communication protocol;
Feedback signal: Analogue and Digital feedback signals with 4 to 20 mA, mechanical and proximity switch options;
PID control: pre-calibrated and user configurable variables via front panel pushbutton menu;
Auto / Manual switch: enables closed-loop automatic valve position control or manual positioning via the A/M switch. The manual mode is useful for troubleshooting, calibration, system testing or as a manual bypass;
HART communication: allows commands, position feedback and diagnostics to be sent digitally over the current loop;
Front panel pushbuttons for configuration: 4 robust and positive acting pushbuttons for field configuration.
