A l l r i g h t s r e s e r v e d .FUNCTIONMode of operationThe actuator is controlled by means of as tandard control signal DC 2-10 V . It opens to the position dictated by this signal . Them easuring voltage Y allows the damper position (0 . . . 100%)to be electrically indicated and serves as a follow-up control signal for other actuators .Simple direct mountingSimple direct mounting on the damper spindle with a universal spindle clamp, supplied with an anti-rotation strap to prevent the actuator from rotating .Manual overrideManual operation is possible with the self-resetting pushbutton (the gearing latch remains disengaged as long as the pushbutton is pressed or detented) .Adjustable angle of rotationAdjustable angle of rotation with mechanical end stops .High functional reliabilityThe actuator is overload-proof, requires no limit switches and automatically stops when the end stop is reached .SAFETY NOTESThe damper actuator is not allowed to be used outside the specified field ofa pplication, especially in aircraft.The device may only be opened at the manufacturer’s site. It does not c ontain any parts that can be replaced orr epaired by the user.The cable must not be removed from the device.When calculating the required torque, the specifications supplied by thedamper manufacturers (cross section, design, installation site), and the air flowc onditions must be observed.lectronic components and is not allowed All locally valid regulations and require-ments must be observed.。

Flowserve Corporation has established industry leadership in the design and manufacture of its products. When properly selected, this Flowserve product is designed to perform its intended function safely during its useful life. However, the purchaser or user of Flowserve products should be aware that Flowserve products might be used in numerous applications under a wide variety of industrial service conditions. Although Flowserve can (and often does) provide general guidelines, it cannot provide specific data and warnings for all possible applications. The purchaser/user must therefore assume the ultimate responsibility for the proper sizing and selection, installation, operation, and maintenance of Flowserve products. The purchaser/user should read and understand the Installation Operation Maintenance (IOM) instructions included with the product, and train its employees and contractors in the safe use of Flowserve products in connection with the specific application.

M03/04智能电动执行机构快速操作指南电动执行机构出厂时，一般以按额定形成90度，反作用方式（用户订货时无形成、作用方式特别要求），即面对输出轴（以下所述方向均以面对执行机构输出轴为准），输出轴顺时针旋转为阀位信号增加的方向调整好。

校验前，应详细阅读产品使用说明，以便校验的正常进行。

一对外接线图二设置说明执行器的工况由工况转换按钮确定，分为本地（LOC）、远程（REM）和禁止（O/S）三种基本模式。

本地工况可手动开关阀门，也可进入设置。

远程工况分为远程开关控制和远程模拟信号4~20mAd.c控制两种，由开关量输入SI1决定。

在远程开关控制工况，执行器的开启由开关量输入SI2，关闭由开关量输入SI3来操作。

执行机构的参数设置及修改通过面板上的MODE，OPEN，CLOSE三个按键进行。

1、操作按键OPEN，MODE，CLOSE（分别对应增加键、模式键、减少键）的功能说明MODE键：在工作LOC方式，长按MODE键5秒可进入设定工况，点动MODE可在菜单之间顺序切换。

如果某些菜单的设置不需要改变，就不必按动增加键OPEN或减少键CLOSE，电动MODE键将依次进入下一个菜单，一直到YES菜单，长按MODE键后就确认当前设置并退出到就地状态。

2、显示信息的规定左边指示灯分别显示执行器的远程、本地、设置、报警4种工况。

上排数码管一般显示阀位开度信号，在设定工况或故障时也可以显示菜单或故障报警信息。

瞎拍数码管一般显示调节信号，在设定工况或故障时也可显示菜单或故障报警信息。

当出现故障时，显示器上报警指示灯亮，有关故障信息需要进入查看故障信息菜单浏览。

显示的工况、故障信息及其含义详见说明书。

三安装说明如果不需要改变执行机构出厂设置的作用方式，安装时应将执行机构操作至CLOSE位置，再与调节机构的机械零位对准联结，如果需要改变作用方式，即输出轴逆时针旋转为开阀的方向时，则在安装时应将执行机构操作至OPEN位置，再与调节机构的机械零位对准联结。
