目录一、概述 (1)二、主要技术参数 (1)三、操作 (1)四、调整 (1)五、注意事项 (2)一、概述整体控制式电动执行机构（以下简称LK）是在2SA30开关型电动执行机构的基础上，增加了电气控制部分，即LK-2型功率控制部分，将机械传动与电气控制集为一体而构成的，具有现场操作和远方操作控制等功能，现场调试极为方便，适用于对开环控制系统中各类阀门进行开关操作和控制。

电控部分由薄膜按键面板、功能板、电源及插件板和交流接触器等组成，电控部分通过插件及紧固螺栓和电动执行机构连接，可方便拆卸或更换；也可实现分体控制。

二、主要技术参数电源：AC 380V 50Hz 三相三线制阀位信号:输出4～20mA(或0～20mA)防护等级:IP67环境温度:-20℃～+60℃输出功率:0.030～15kW三、操作LK可分别在“远方”或“就地”状态下操作，当每次接通电源后均处于“远方”状态，“就地”操作按键不起作用，如果需要进行“就地”操作时，需将面板的下部盖板打开，按一下“就地”按键，将“远方”状态切换至“就地”状态，此时，“远方”状态指示的绿色发光管熄灭，“就地”状态指示的红色发光管亮，在远方控制室内，“远方操作指示灯”熄灭，远方操作的“开、关、停”按键不起作用，只能在就地操作面板上操作“开、关、停”按键。

在“就地”或“远方”操作时，操作面板的高亮度发光管和远方操作盘上的指示灯同时显示阀门开关位置或工作状态：在开启阀门过程中，红灯闪，绿灯亮在关闭阀门过程中，绿灯闪，红灯亮阀门处于“全开”位置，红灯亮，绿灯灭阀门处于“全关”位置，绿灯亮，红灯灭“就地”操作结束后，应按一下“远方”按键切换至“远方”操作状态，并将面板盖上，以防误操作。

The front panelincludes a unique in t er a c t ive display of chan n el status for quick pro g ram-ming. Scanning speeds of up to 300 channels per second are possible withthe high density switch cards. The wide selection of more than 30 d ifferentswitch cards makes the 7002 one of the most flexible switch i ng main-frames avail a ble.Reduce the Size and Costof Your Switching Application.up to 400 channels of 2-pole switching. A single Model 7002 mainframecan accommodate up to ten 40-channel cards. That’s 400 channels in asingle full-rack package that is only 178mm high (7 in). This level of density provides some impor-tant advantages. First, it reduces the amount of switching hardware required for a given ap p li c a t ion. Second, it provides high flexibility. The high density cards can be used with the special signal cardsto cover all your signal needs for a large application with one m ainframe.The 7002 is fully compatible with all 7001 switch cards. From thisf ig u r a t ion flex i b il-a m p le, the outputs of a mul t ip lex e r card can be connectedt i p lex e r cards can be con n ect e d to formlex e r.

When the high density cards are installed,the 7002 au t o m at i c al l y configures each slot independently for the propercard. The channel status display on the front panel adjusts to show eachcard’s capacity and con f ig u r a t ion.Front panel info key. At the touch of a button, the operator receives con-text-sensitive, on-line information to help configure the system. This infor-mation is displayed on a 52-character alphanumeric display for clear andreadable messages. There is no need to refer constantly to the operator’smanual. All information messages, operating instructions, and prompts areavailable in English, German, and French. Just select the desired languagein the con f ig u r a t ion menu.Programmable channel closure restrictions. The 7002 allows specificchannels to be locked out from closure. This restriction can be conditionalbased on the open/close state of other channels or crosspoints. This capa-bility is useful to prevent certain signals from being accidentally connectedto high power circuits, for example.DC, RF, and optical switchcapabilityInteractive channel statusdisplaySERVICES AVAILABLE7002-3Y-EW 1-year factory warranty extended to 3 years from date of shipment19811.888.KEITHLEY (U.S. only)A G R E A T E R M E A S U R E O F C O N F I D EN CE7002 7002Switch/Control Mainframe400-channelSystem Throughput300 channel per second scanning. The 7002 can scan through up to 300 chan-nels per second. This scan process can be controlled by the internal time base of the 7002 or through external triggers. The scan sequence is con t rolled by what appears in the scan list. The scan list can include channels, ranges of channels, and memory locations. This ap p roach gives max i m um flexibility while obtaining maximum through p ut.Built-in Scan Control and trigger Link. The built-in scan control eliminates the need for the computer to control every step of the test pro-cedure. Simply program the 7002 to control the channel spacing, scan spacing, and number of scans.
