Electric valve intelligent locator-The Yangzhou Bernard valve automatic control Equip

Electric valve intelligent locator is based industrial microcontroller as the core of the intelligent signal acquisition and control system, compact, choose to install the junction box of the electric actuator or fixed outside a DIN rail, industrial instrument or computer can directly receivethe output of 4-20mA/DC signal (the other type of input signal can be customized at the factory before) with potentiometer feedback electric actuator supporting a variety of valves or devices for precise positioning operation of the electric actuator corner (ordisplacement) free calibration, at the same time the output 4-20mA/DC actuator corner position (or displacement) feedback converted signal can be the key to accurately set the actuator corner position the lower limit value and upper limit value, locator using 3button operation, nine LED lights can be displayed directly to the locator modal 4 digital LED display valve position, the actual value, the valve position to set the opening value, the shell temperature of the locator, easy to operate through the key switch.

参数显示	1	LED视窗	通过按键切换显示阀门实际开度值、阀门设定开度值、定位器壳内温度和设定参数
状态指示	2	OPEN	输出控制“开 ” 继电器闭合
	3	SHUT	输出控制“闭”继电器闭合
	4	MANU	手动状态
	5	AUTO	自动状态
模式指示 (MODE)	6	DRTA	正动作模式，输入信号对应输出如下： 4mA — 满位( 一般标定为全开 ) 20mA — 零位( 一般标定为全闭 )
	7	RVSA	逆动作模式，输入信号对应输出如下： 4mA — 零位( 一般标定为全闭 ) 20mA — 满位( 一般标定为全开 )
	8	OPEN	输入信号中断模态为“开” , 使执行器开至最大开度限位处
	9	STOP	输入信号中断模态为“停” , 使执行器停在当前位置
	10	SHUT	输入信号中断模态为“闭” , 使执行器开至最小开度限位处
按键	11	A/M	手动 / 自动切换键，参数的进入修改和切换键
	12	▲	数值增加键，自动状态下还用于切换显示阀位设定开度值，手动状态下为“开”
	13	▼	数值减少键，自动状态下还用于切换显示定位器壳内温度，手动状态下为“闭”

Control accuracy: 0.1% -3.0% (U4 parameters adjustable)
Electric actuator feedback signal which can be accessed: potentiometer 500Ω to 10KΩ
Can receive an external control signal (DC) :4-20mA (1-5V ,0-10V, switch factory custom)
Input impedance: 250 Ω;
Can be set by modifying the U1 parameters: the ① DRTA / positive action, the RVSA / action mode inverse state ② the input signal is interrupted "interrupt" mode - OPEN (open), STOP (stop), SHUT (closed)
Optional: ① The SCR output (AC, 600V, 25A)
② Relay Output (AC 250V, 10A) ◆ When ordering, specify the
The actuator position signal output: low drift output 4-20mA DC corresponding to the actuator is fully closed to fully open, the signal is completely isolated from the input (optical isolation), the output load ≤ 500 Ω
Ambient temperature :0-70 ° C, humidity :35-85%
Over-temperature protection: Locator shell temperature ≥ 70 ° C, the locator to stop the opening and closing of the actuator control
Dimensions: ZXQ2003 → 77mm (underside) x76mm (bottom wide) x51mm (H));
ZXQ2004 → 74 mm (underside length) x57mm (bottom wide) x45mm (H) calibration freely through the key input signal corresponding to the action range of the actuator (typically calibration for the electric actuator is fully closed, fully open position)
Can set upper and lower limit points
Actuator stall detection and control functions: such as control of the actuator stall stall continuous 3-4S, locator, disconnect the control output 1min; repeated measurement and control, to exclude.
Can be set to the accuracy of self-adjusting: the actuator in the course of their work, can not locate, and three times back and forth vibration locator automatic positioning accuracy down to 1/1000 (ie: the original accuracy of +1 / 1000), repeatedly adjusted to a suitable control accuracy. Set the parameters for U0 (000.x)
Lock: to prevent misuse
Anti-actuator frequent start function ● with error code indicates the cause of the malfunction (E_0X)
Intelligent step to adjust the precise positioning of the corner position of the input signal and actuator
Three. The locator panel, such as customer purchase orders specified in the configuration of this Z-(mechatronic) actuator, you do not need calibration actuator corner, the wiring is correct to normal use.
