ECM-2C型控制模块使用说明  ECM-2C型控制模块是以AC220V单相交流电作为电源，接受来自PLC、DCS系统或其它操作器的DC4-20m A信号，控制执行器进行开关动作，构面全电子式电动执行器。一、            主要技术特点输入电压范围：AC180V-245V控制模块具有刹车功能，***提高了阀门的定位精度输入/输出信号均经过光电隔离（可承受2000V浪涌电压）位置反馈4-20mA信号负载电阻，50Ω-700Ω，精度：0.5%三电位器调节技术使用4-20mA反馈可一次调节完成，大大简化调节过程若输入信号丢失，执行器将根据用户事先在模块上的拨码选择使阀门或保持原位不动，或动作到阀门全开位置，或动作到阀门全关的位置工作温度范围：-30℃~+55℃ 二、            使用方法 1、线与拨码选择  ECM-2C型模块按下图所示完成模块与执行器接线。位置电位器的阻值应为≥1KΩ 用万用表检查模块上的电机边线端，确保无短路现象。以上连线检查无误后，接入220V电源线。 2、调试先通过执行器上的手轮将执行器动到全行程的中间位置。在无控制电流(及丢信)情况下，将丢信动作拨码开关拨到“开”位置，接通AC200V电源，此时电源批示灯和丢信指示灯点亮，执行器应向开方向动作：将丢信动拨码开头拨到“关”位置，此时执行器应向关方向动作：将丢信动作拨码开关拨到“停止”位置，此时执行器应停止动作：若执行器动作相反，应将“电机开”和“电机关”接线交换。 <阀位反馈电流调试，将执行器动作到关位，调节“调零”电位器，使测试点两端的电压差为零，然后调节“低端”电位器使输出信号为4mA;将执行器动作到开位，调节“高端”电位器使输出信号为20mA。上述调节只需一次即可完成（“调零”、“低端”和“高端 ”电位器均是顺时针方向增大，逆时针方向减小）。注意：当阀位由关到开时，阀位电位器中心轴头对地GND电压的值应由小到大变化。为了***执行器在自动控制中的定位精度，须调节灵敏范围。灵敏度范围小，定位精度高，但容易产生振荡。灵敏度范围大，不容易产生振荡但定位精度差。调节“灵敏度”电位器可以二位这间取折衷，使其不产生振荡为调节值 注意：1灵敏度电位器，为单圈270°电位器，到位后不要用力旋转，否则会损坏电位器。

ECM - 2 c control module USES the ECM - 2 c control module as AC220V single-phase ac power supply, accept from PLC, DCS system or other operator DC4-20 m A signal, control switch actuator movements, dimensions all electronic electric actuators. One, the main technical features of the input voltage range: AC180V - 245 - v control module with brake function, greatly improve the positioning precision of the valve input/output signals are through the photoelectric isolation (affordable surge voltage 2000 v) position feedback 4-20 ma signal load resistance, 50 Ω Ω - 700 precision: 0.5% three potentiometer control technology using 4-20 ma feedback can adjust once completed, greatly simplify the adjustment process if the input signal is missing, actuators will choose according to users in the dial on the module code in advance to keep the valve or in situ, or action to the valve fully open position, or actions into valve seated position working temperature range: - 30 ℃ ~ 55 ℃ + 2, use method 1, line and dial the code selection ECM - 2 c module according to the complete module and actuator wiring shown below. Position potentiometer resistance should be 1 k or higher Ω line on the motor end with a multimeter to check module, make sure no short circuit phenomenon. Above attachment to check and correct, access to 220 v power supply cord. 2, debugging, by means of the handwheel actuator will first actuator move to the middle position of the whole trip. In the absence of control current (and lost the letter, will throw the letter action dial the code switch to "on" position, through to AC200V power supply, power designator light and threw the letter light is lit, actuators to the direction of action: open letter will lose move dial code set to "off" position in the beginning, the actuator to close direction action: action will throw letter dial the code switch to "stop" position, the actuator should stop action: action, on the other hand, if the actuators should be "motor" and "electricity authority" connection exchange.
