The light-emitting diode (LED) of the switch is on when the load is energized.Figure 4 - Typical Connection Wiring DiagramGroundingThe 802PR limit switch does not require a ground connection. The load side of the 110/120V AC source can be grounded as shown in Figure 5.Shortcut Circuit ProtectionWe recommend using a fast acting Type KAW10 or KAX10 fuse in the circuit to provide short circuit protection for the switch.Series Connected SwitchesNormally Open Fixed OutputDo not connect two or more switches in a series. Doing so can result in erratic operation.Programmable Normally Open (N.O.)/Normally Closed (N.C.) OutputTwo switches can be connected in series with a load. For proper operation, the operating load voltage must be less than or equal to the minimum supply voltage less the sum of the on-state voltage drops across the series connected proximity switches. The load energizes when the output LEDs of both proximity switches are on.Figure 5 - Connection DiagramSpecificationsProgrammable Output SelectionThe programmable N.O./N.C. proximity switch is factory preset in either thenormally open or normally closed output mode. To change the switch output mode:1.Remove the lower legend plate on the front of the switch.2. A line on the recessed rocker indicates the output mode of the switch. Tochange the output, depress the recessed rocker of the switch with a pointed tool.3.Replace the lower legend plate.ATTENTION: If a hazardous condition can result fromunintended energization of this device, access to the sensing area must be guarded.To guard against the load remaining energized when the switch is in an open condition, the minimum load release current must be greater than the maximum leakage current of the proximity switch.L 1L 2Description Output ModeFixed N.O.Programmable N.O./N.C.Operating voltage range102…132V, 50/60 Hz60…132V, 50/60 HzLoad current Max continuous: 1 A to 40 °C (104 °F)linearly derated to 0.5 A at 75 °C (167 °F)Max inrush: 10 A, 1 second maxMin: 0.025 A Max leakage current (load off)0.0065 A0.0035 AMax voltage drop (load on)7.5VOperating temperature range-25…+75 °C (-13…+167 °F)Max operate time 25 ms 25 ms Max release time 35 ms25 ms Delay on power-up targetpresent20 ms, typical (no output occurs with target absent)Sensing distance Steel: 13.33 mm (0.525 in.) +10% -5% (Figure 1 on page 1)Nonferrous metals: 6.35 mm (0.25 in.) typicalHysteresis(operate — release differential) 1.9 mm (0.075 in.) maxSensing distance drift withtemperature ±5%0…75°C (32…167°F)±10%-25…+75°C (-13…167°F)±5%15…50°C (59…122°F)±10%-25…+75°C (-13…+167°F)Max sensing distance drift withvoltage ±0.5% 102 (132V)±1% 90...132V ±3% 60 (132V)Repeat accuracy (10 successive operations)0.03 mm (0.001 in.) max deviation at constant temperatureand supply voltageOperating speed (operations per minute)(1)(1)Based on max operate and release time10001200ATTENTION: Do not connect two or more 802PR limit switches in parallel.

The output LED is on when the switch output is conducting.Hard Wired ContactsA surge suppressor must be connected in parallel with the load when hard wired contacts are connected in parallel with the 802PR limit switch. Surge suppression is not required when hard wired contacts are connected in series with the load. For recommended surge suppressors for various devices, see publication PROX-TD001.Conduit Coupled SwitchesThreaded conduit opening bases are suitable for use with flexible conduit. Conduit coupler bases are suitable for use with both flexible conduit and rigid conduit. Both bases connect to 12.7 mm (0.5 in.)-14 NPT threaded conduit. Switches with catalog numbers that contain a ‘S6’ suffix are suitable for connection to ISO 20-1.5 threaded conduit.Prewired Cable SwitchesThis type of switch includes a prewired cable for connection directly into a junction box. The cable is a two-conductor, oil-resistant thermoplastic (STO).Prewired Receptacle SwitchesThis type of switch includes a prewired receptacle suitable for use with theconnector-cable assemblies that are listed inTable 1. Figure 7 indicates which twopins of the receptacle are wired internally to terminals 1 and 2. The third pin is not used.Figure 7 - End View of Prewired ReceptacleTroubleshooting GuideThe following guide provides basic troubleshooting information for installation and use of the proximity switch. If a problem occurs, attempt to determine the possible cause, as listed, and apply the suggested solution.Hard wired contacts that are operating in series or parallel with the Bulletin 802PR Type LA or XA limit switch cause a delay ofapproximately 200 ms. This power-up delay reduces the maximum number of operations per minute and can result in a momentary de-energization of the load.Table 1 - Connector Cable (Supplied by User)ManufacturerConnector Cable Part Numbers0.9 m (3 ft) cable1.8 m (6 ft) cable3.7 m (12 ft) cableStandard Color Code (green, black, white)Brad Harrison409014090240903Joy X8984-38984-48984-5CAM-LOK E2057-624E2057-625E2057-626Automotive Color Code (green, red, red)Brad Harrison409584095940960Joy X8984-13X8984-14X8984-15CAM-LOKE2057-824E2057-825E2057-826Normally closed modeNormally open modeDepressed recessed rocker near indication line to change output modeShort Pin -Connects to Terminal 1Short Pin -Connects to Terminal 2The switch can continue to operate even if the LED is damaged (will not light).SymptomOutput LED (1)(1)Programmable N.O./N.C. switches have two LEDs.

接近开关使用说明书感谢您对广东东崎电气有限公司产品的信赖，当您使用我公司产品时请务必参阅本说明，以免因操作失误而造成不必要的损失。

例：TKI-12N4C表示直插式插头连接型,直流电感式接近开关，外形为M12圆柱型，NPN常开，动作距离为4mm，最大输出电流为200mA.二、距离的设定※开关的动作距离请设定在80%检测距离（Sn）内，以免开关工作受温度、电压等影响。

※当检测其它金属时，开关有不同的动作距离。

(图1)※当开关用作测量动作频率或其它高速场合，请将开关的动作距离设定在1/2检测距离(Sn)，开关在此位置可获得最大的动作频率。

※电容式接近开关的动作距离设定，请参阅电容式接近开关的使用说明。

(见五)不锈钢铬镍铜铝二、接线图PNP(直流型)三、串联及并联NPN(直流型)直流二线型检测距离交流二线型(图1)电源电源交流串联交流并联若电源电压为220V，且串联数在3个以内，可使用上图的接法，否则请按下图方法通过继电器进行串联。

并联的开关A和B，若检测体接近开关A，开关A动作，负载电流流过开关A，开关A（B）两端电压降为10V，若此时检测体再接近开关B，因开关两端的电压为10V，开关B会因电压不足而不动作，只有当关闭开关A，使A（B）两端的电压升高至使用电压，开关B才动作，开关A关闭与开关B动作的时间间隔约为10mS，因而当需要多个接近开关并联时应注意开关相互之间的影响，一般请按下图通过继电器进行并联。

电源AC 电源※直流电源必须使用绝缘变压器，请勿使用自耦变压器；※电力线、动力线通过开关引线附近时，为防止开关误动作和损坏，请使用金属配管线。

四、注意事项※交流型开关,若电源电压为110V时,串联必须经过继电器使用；※交流型开关必须经过负载接电源,若直接将开关接电源会损坏开关。

电源AC 电源×错误接法√正确接法※接近开关的引线长度请在200米以下，以免电压降过大。

五、电容式接近开关的使用说明※电容式接近开关不仅能检测金属，而且能检测塑料、玻璃、水、油等物质，因各种检测体的导电率和介电常数、吸水率、体积的不同 故相应检测距离也不同，对于接地的金属可获得最大的检测距离。

■限位开关的概念限位开关，指为保护内置微动开关免受外力、水、油、气体和尘埃等的损害，而组装在外壳内的开关，尤其适用于对机械强度和环境适应性有特殊要求的地方。

形状大致分为横向型、竖向型和复合型。

下图表示典型的竖向型限位开关的构造。

限位开关大致上是由五个构成要素组成的。

■内置微动开关驱动机构对于限位开关来说，微动开关的驱动机构是与密封性能和动作特性直接相关的重要部分。

其构造分为三类，如下表所示。

（1）活塞型根据密封方法不同，有表中的A型和B型2个种类。

A型是用O型环或薄膜密封的，由于密封橡胶没有外露，在抵制工作机械的切割碎屑方面功能较强大，但其反面影响是，有可能会将砂子、切割粉末等压入活塞的滑动面。

B型虽然不会把砂子、切割粉末等压入，且密封性能优于A型，但由于炽热的切割碎屑飞溅过来，有可能会损坏橡胶帽。

因此，要根据使用场所的不同选用A型或B型。

而柱塞型仍然通过柱塞的往复运动压缩或吸进空气。

为此，如果长时间将柱塞压入，限位开关内的压缩空气逸失，内部压力将与大气压相同，即使急于让柱塞复位，柱塞却有迟缓复位的倾向。

为了避免发生这种故障，设计时，根据柱塞的压入将空气的压缩量控制在限位开关内部全部空气量的20％以内。

另外，为了延长微动开关的寿命，在这一构造内部设置了一个OT吸收机构，该OT吸收机构采用OT吸收弹簧，用以吸收残余的柱塞的行程。

该机构相对于柱塞的运动，在中途停止按压微动开关辅助柱塞的行程。

（2）铰链摆杆型在摆杆端部（滚珠），柱塞的行程量根据摆杆的比例扩大，因此，一般不使用OT吸收机构。

（3）旋转摆杆型举一个典型的示例，来示例WL的构造，但除此之外，还有两个类型：将复位柱塞的功能赋予柱塞的类型；通过线圈弹簧获取复位力、用凸轮带动辅助柱塞的类型。

■开关的构成材料开关的主要部分是由下列材料构成的限位开关用语说明限位开关：为保护小型开关不受外力、水、油、尘埃等的侵害而将其装入金属外壳或者塑料外壳中的开关。

基于PLC控制的水电站闸门越限防护的研究与实现摘要：为了保证水电站闸门安全可靠的运行，必须对闸门行程进行上下限位。

传统的限位措施是在闸门控制系统中安装相应的机电限位装置，该措施单一但可靠性不足，更不能检测闸门开度。

提出一种闸门越限防护的双重机制：将旋转限位开关及编码器相结合，有效地实现闸门开度检测与行程限制。

关键词：越限防护开度检测中图分类号：tv734 文献标识码：a 文章编号：1007-3973（2013）005-024-031 闸门越限防护必要性水电站卷扬式闸门启闭机运行时，如果闸门上升到顶部极限还在运行，则会引起闸门拉弯变形、钢丝绳拉断以及水坝枢纽受损等重大事故，给水电站造成巨大的损失。

因此，必须对闸门进行上下限位，确保闸门安全准确的停止。

目前，水电站闸门越限防护采用的是机械限位，即在卷扬式启闭机上安装相应的机电限位装置，这种方法虽然简单，但是单一的限位措施可靠性不足。

本文提出了一种闸门越限防护的双重机制：将旋转限位开关及编码器限位相结合，有效地完成闸门开度的实时检测与行程限制。

2 越限防护的机制2.1 基于旋转编码器的越限防护（1）编码器的安装。

由于电机转速较快，而绝对式编码器的量程有限，所以编码器不能直接安装在电机的主轴上。

但是，电机主轴输出的转速在经过减速箱传递到钢丝绳的卷筒时，转速就小很多。

将绝对式编码器安装在卷扬机的卷筒上，使编码器的主轴与卷筒同步转动。

其优点有：1）编码器量程满足要求，编码器能发挥越限防护作用；2）卷筒转速低且转动平稳，可以避免由于高速震动使编码器损坏的事故；3）编码器拆卸方便，容易进行维护养。

（2）工作原理。

编码器的原理：编码器是用来测量角度、位置的传感器，依靠轴杆、齿轮、测量轮的控制，检测线性的位移。

编码器将实际的机械参数值转换成电气信号，这些电气信号经plc处理，形成控制系统所要求的参数。

越限防护原理：编码器与卷筒同轴连接，随着卷筒同步转动，卷筒每转动一定的角度，闸门就提升一段距离，编码器累加一定的脉冲数。
