江苏兰 valve General Equipment Co., Ltd. is one of the production factory equipment and complete sets of valves valve drive. Product is fully functional, reliable performance, advanced control system, easy maintenance, the module image, is widely used in electricity, metallurgy, petroleum, coal, chemical, paper and other parts. Intelligent electric device operating method, debugging · to move the actuator to the middle position of the whole trip through the hand wheel on the actuator. ? Turn on the power AC380V, then the power indicator light, according to the control board (see Figure 3) "live" switch to make "live" lights on. Press the "off" button, then the direction of the actuator action should be closed; press the "start" button, then the direction of the actuator action should start; press "stop" button on the module, then the execution should stop operation ; if the opposite direction of the actuator switch should then swap any two wires at the motor connected. · Position feedback 4 ~ 20mA signal conditioning. The actuator movement to the closed position, adjust the "zero" potentiometer, the voltage difference between the two test points is about zero (≤2mV), integral module, and then adjust the "4mA" potentiometer allows the output signal is 4mA; will perform is the action to the open position, adjust "20mA" potentiometer allows the output signal is 20mA. Said adjustment can be completed only once. Note: When the valve from the closed to the open position, the valve position potentiometer center tap voltage of the absolute value of the ground GND should be from small to big changes.江苏兰 intelligent multi-turn valve electric device works IFML IFM intelligent electric devices are multi-turn electric actuators on the basis of intelligence, a combination of additional trapezoidal lead screw nut, flange bracket and the regulated institutions. Converting rotary torque and speed of travel and exercise our powers in a straight line shaft thrust. Intelligent rotary electric device is based on the IF, IFM intelligent multi-turn electric devices on supporting a combination of two worm gear reducer. Integral module _-valve Electric (certified) _ module provided by 江苏兰 valve General Equipment Co. Jiangsu Lan valve General Equipment Co., Ltd. (www.lanfa.cn) Changzhou, Jiangsu, regulating valves leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In Jiangsu Lan valve leadership with the staff warmly welcome all inquiries negotiations to create a better future for Jiangsu Lan valve.
