Supply of electric smart regulation valve Dongguan FHa

HF intelligent electric valve positioner instruction manual I. Introduction HF2008A series of intelligent electric valve positioner industrial intelligent control chip as the core, with electronic circuit designed to achieve precise positioning of the valve function by controlling the electric actuator and other equipment. Locator can receive industrial instruments or sensors potentiometer output 4-20mA current signal and the electric actuator feedback signal, and can output 4-20mA actuator angle (or displacement) feedback signal converter can be adapted to a variety of applications and requirements. Locators have a good man-machine interface, equipped with three buttons, nine separate LED indicators and four digital control, real-time display of angle (or displacement) ratio, system setup parameters, actuator status and other types of information, while receiving various types of user key input commands to achieve hand / automatic switching, mode setting, calibration settings, easy to operate and powerful. Second, the Panel Description 1. Description of function keys (1) A / M key: A. manual / automatic mode switch; under B. Manual mode, press 2 seconds to enter the calibration mode, the calibration mode C. wait for the next calibration results storage and confirmation; (2) ▲ key: A. manual mode control motor forward; switching the actual opening of the valve and controlling the opening of the next degree B. automatic mode display; do accumulate key under C. calibration mode; (3) ▼ Key: A . In manual mode control motor reversal; do decrement key under B. calibration mode; 2, the digital display description (see Table 1) (1) Manual mode, the display corresponding valve opening, the display range from 0.00 to 100.0 limit; (2) the automatic mode, the normal state shows the current valve opening, the display range 0.00 to 100.0; (3) the calibration mode, each display calibration function description, see the specific meaning; 3, the status LED Display Description (1) OPEN : electric actuator control output circuit "on" output is active; (2) SHUT: electric actuator control output circuit "closed" output valid; (3) MANU: positioner is in manual mode; (4) AUTO: The positioner is in automatic mode;
