功能 Functions

 

基本功能 Basic functions

 

旋转运动 Rotary motion

——执行器的转动方向(顺时针或逆时针)可以通过DIL开关进行选择。

——一旦接收到输入信号(>0V),执行器即向“90°”方向旋转。只要控制信号不变,则执行器保持位置不变。

——当控制信号中断而工作电压仍保持时,执行器返回到所选择方向的0位上。

——当工作电压中断时,执行器将保持在其当前位置上。

 

	
-

	
The rotation direction of actuator (clockwise or anticlockwise) is optional via DIL switch.

	
-

	
The actuator rotates towards “90°” direction as long as receiving the input signal (>0V); Otherwise, it would keep static.

	
-

	
The actuator will go back to 0 location at the selected direction while the control signal is off and working voltage on.

	
-

	
The actuator will keep the current location when the working voltage stops.

 

位置指示 Location indicating

——机械位置:位于外壳上的位置指示器可以显示出风阀的转角位置。

——电气指示:执行器的电子线路可以产生出0°...90°转角范围成比例的DC0...10V输出电压。该电压可用作位置指示。

 

	
-

	
Mechanical location: on the casing where the indicator may display the rotating angle position of the air valve.

	
-

	
Electric indicating: the electronic circuit of actuator could generate DC0...10V output voltage pro rata to 0°...90° rotating angle scope.

 

  

  

  

 

手动设置 Manual setup

在无电供给时,可通过红色推钮接执行器中的齿轮组作用,手动调节执行器或风阀的位置。

 

In case of no power supply, use the gear set function in actuator via the red button to adjust the locations of actuator or air valve by hand.

 

转角的机械限位 Mechanical limit of rotating angle

旋转角度可在0°...90°之间限定。

旋转角度范围自适配:执行器自动测定旋转角度的机械终点。

 

The rotating angle could be limited within 0°...90°.

 

The rotating angle is adaptive: actuator automatically determines the mechanical destination of rotating angle.

 

特定型号的执行器功能 Specific actuator functions

 

控制信号的调整 Control signal adjustment

(操作功能) Operating function

旋转角度的偏置和区间可以通过两个电位器进行调整。

·可以利用DC10V的控制信号对转角范围有限制的风阀进行控制。

·在只能应用0...10V控制信号的控制回路中作为顺序执行器以控制多个顺序。

·用于采用非0...10V控制信号的控制系统。

 

The offset and interval of rotating angle could be adjusted via two potentiometers.

 

Use control signal of DC10V to control air valve with limited rotating angle.

 

Act as sequence actuator to control several sequences in the control loop where only 0...10V control signal can be used.

 

Use for the control system adopts non 0...10Vcontrol signal.

 

辅助开关的调整 Auxiliary switch adjustment

辅助开关可以为执行器提供额外的功能。在0°...90°的转角范围内,开关A和B(每个均为转换开关)可以按照5°增量分别独立设置。

 

The auxiliary switch could provide actuator with extra functions. Within 0°...90° rotating angle, switch A and B (both change over switch) could be separately set according to 5° increment.

Function of Spring Return

All SK...62...actuators are designed with spring return function in the factory. In case of power failure or lack of control signal, the spring may return to let the actuator return to the “0%” stroke position.

SK...60 actuators are not designed with spring return function. In case of power failure the actuator will stay at current stroke position.

Compulsory Control Function

There are three operating modes of the compulsory control input point (Z):

	
w/o such function

	
Compulsory control for 0...1000 Ω signal

	
 

 

-     Disconnected Contact Z

-     Valve stroke following control signal Y

	
 

 

-     Z is connected to Contact M through resistor R

-     Characteristics of linear or equally proportional flow

-     Starting from 50 Ω / Ending at 900 Ω

-     Point Y not to function

	
Fully opened valve

	
Fully closed valve

	

 

-     Contact Z directly connecting to G

-     Point Y not to work

	

 

-     Z Contact directly connecting to G0

-     Point Y not to work

Note: For Mode Z, assumption is made for setting of FORWARD in the factory.

Stroke Checking

Checking is required upon the first match between the valve and the actuator to determine the 0% and 100% stroke position of the valve. To this regard, mechanical connection is required between the valve and the actuator (See Section of Compatibility); the power supply is AC 24V. The checking process can be described repeatedly.

 

	

	
Prior to checking, make sure that the manual regulator is changed over “Auto” mode for recording an actual valve.

 

  

  

  

 

	
In order to commence the checking, the inside of the lockhole in the actuator’s typeplate must be short-circuited (for example, with screwdriver).

Auto checking procedures are as follows:

	
     

	
l Change the actuator over 0 stroke (Position (1)), the valve closes and the green LED light flashes.

l Then change the actuator over 100% stroke (Position (2)), the valve opens and the green LED light is ON.

l Save the measurements. The checking process ends. The green LED light is ON (Running normally).

l Change the actuator over positions controlled by control signal Y or Z(3).

l This process shows that Output Point U does not work, for example, the valve only act to represent the actual position when the green LED stops flickering or continues to keep shining

Engineering Precautions

Electrical connection of actuators must meet the requirements of local regulations and the wiring diagram in Page 12.

	

	
Strictly follow all the safety regulation and requirements to prevent from damage and injury.

Valve Stem Heating Element ASZ6.5 can generate a heat output of 30VA, and valve stem must avoid freezing when Operating in refrigerating range 0...-25°C.

In this case, the actuator bracket and valve stem need not be insulated to ensure proper air circulation.

The body in contact with the non-insulated hot element may possibly be scalded.

Failing to follow the above-mentioned recommendations may possibly result in accidents or fire.

Follow the permissible temperature range (See Application and Technical Data).
