(DV6300B)隔爆型智能定位器采用微處理器和新型壓電閥代替傳統定位器中的噴嘴、擋板調壓系統來實現對輸出壓力的調節控制。通過CPU運算處理來實現對閥門開度的輸入信號和閥位的反饋信號的控制。壓電閥由于質量小，可以釋放很短的控制脈沖，從而達到很高的定位精度，且壓電閥只有在閥門有偏差并執行調節動作時才耗氣，所以可以實現低耗能的目的。

retz品牌 Dv6300b flameproof intelligent positioner adopts microprocessor and new piezoelectric valve to replace the pressure regulating system of nozzle and baffle in traditional positioner to realize the regulation and control of output pressure. The input signal of valve opening and the feedback signal of valve position are controlled by CPU operation and processing. Due to its small mass, the piezoelectric valve can release a very short control pulse, so as to achieve high positioning accuracy, and the piezoelectric valve only consumes gas when the valve has deviation and executes the adjustment action, so the purpose of low energy consumption can be achieved.

注意∶

電氣線纜必須用屏蔽雙絞線或屏蔽線。并將線纜屏蔽層一端連接設備外殼 處的螺釘或殼體內 處的螺釘，另一端連接大地。從而使設備有效接地，防止電磁干擾。Electrical cables must be shielded twisted pair or shielded wire. Connect one end of the cable shielding layer to the screw at the equipment shell or the screw in the shell, and the other end to the earth. Thus, the equipment can be effectively grounded to prevent electromagnetic interference.

電氣線纜鋪設要遠離強磁場環境 Electrical cables should be laid away from strong magnetic field environment.

請在設備斷電情況下連接或拆卸電氣線纜 Please connect or remove the electrical cables when the equipment is powered off

HART通信接線方式∶將 HART調制解調器或 HART手操器的兩根信號線分別接到 4-20 mA 設定信號的正負極上 HART communication wiring mode: connect the two signal lines of Hart modem or Hart manual operator to the positive and negative poles of 4-20 mA setting signal respectively.
