First, Product Overview
XCN5000 intelligent electric valve positioner, the use of fully digital operation and operation, suitable for straight travel or angle of pneumatic actuators. Single action and double action way with use. The locator is a two wire system instrumentation, provide PID regulating function, but as a regulator and positioner of the high intelligent control device. Locator 4 ~ 20 mA by the input signals to control, PID control by + 24 VDC power supply output series circuit with the transmitter. At the same time, it will in addition to the complete controller output current signal is converted into the main functions of the drive regulator, has in accordance with the valve stem friction at work, offset by the change of the medium pressure caused by the unbalanced force, so that the valve opening corresponding to the regulator output control signals to achieve the correct positioning. Supports HART communication protocol.

Third, Installation Instructions
1, The main shaft to locator links with pneumatic actuators. Output pipe connections are not allowed to have leakage phenomenon.
2, Press the "+" and "-" key combination to drive the valve in the opening half, watch the display value whether in 50% if not, turn the gear set, make it within this range; Press the "+" with "-" key combination, drive valve observation screen valve position values are within the scope of the following change; A, Straight trip (20%-80%). B, The Angle of stroke (5%-95%).
3, At the same time hold the function keys and "+" key is more than more than 5 seconds, start automatic initialization.
4, After the success of the initialization according to FINSH, press function model is greater than 5 seconds to exit.
5, Hold the function key is greater than 5 seconds to enter the menu click "+" 3key changes value, and then click"-"key recovery value. Press mode key is greater than 5 seconds to save and can.
