The respective mode is defined by entering the corresponding configuration and setting parameters via the push buttons on the con-troller or the software tool.The RWD32 and RWD82 controllers can be programmed as follows:• 2-position controller:Q1 and Q2reverse and/or direct acting on each step • 3-position controller:Q1 or Q2reverse or direct actingONONLoad2 Reverse Acting Sequences (Dependent loops)(Application No.: 10-19)2 Direct Acting Sequences (Dependent loops)(Application No.: 50-59)LoadLoad2 Reverse Acting Sequences(Independent loops)(Application No.: 20-29)2 Direct Acting Sequences (Independent loops)(Application No.: 60-69)Reverse and Direct Acting Sequences(Application No.: 40-49)Software ToolController typeMain functionsDependent Control LoopsIndependent Control LoopsReverse and Direct Acting Control Loops4/11LoadReverse Acting Sequence (Application No.: 30-39)Direct Acting Sequence (Application No.: 70-79)The universal input X1 is used as the primary input for a Landis & Staefa Ni 1000 tem-perature sensor, a Pt 1000 temperature sensor or a 0…10 V DC active input.The universal input X2 is used as the secondary input for a Landis & Staefa Ni 1000temperature sensor, a Pt 1000 temperature sensor, an active / passive remote setpoint transmitter or a 0…10 V DC active input.The digital input D1 is used to select the day/night changeover. Changeover occurs via potential-free contacts between D1 and M.Each output Q (Q1, Q2) can be configured for either reverse or direct acting.Ventilating plant with temperature controlX1Room temperature Q1Heating, reverse action Q2Cooling, direct actionOne of the following auxiliary functions can be selected:• PI limiter function (Absolute & Relative)• Remote setpoint function • Cascade control function • Setpoint compensation • Winter/summer operation • Maximum priorityAdditionally, the day and night operation mode is available.The limiter function with PI control enables abso-lute(or relative) maximum or minimum limitation of the supply air temperature (X2).When the value drops below or exceeds the limiter setpoint, the limiter function controls and takes prior-ity over the main setpoint.3341s 02A remote setpoint transmitter (FZA21.11, QAA25 or QAA25/AP), connected to X2 and configured ac-cordingly, enables setpoint adjustment.Active measurement from 0...10 V DC corresponding adjustable range from –100 to 8000Passive measurement from 0…1000 Ω correspond-ing adjustable range from –100 to 80003341s 033-point Control LoopUniversal input X1Universal input X2Digital input D1Digital outputs Q ExampleAuxiliary functions PI limiter functionRemote setpoint5/11X2 Supply air temperature sensorYou can select the PI/PI room/supply air tem-perature cascade control . In this case, the virtual PI room temperature controller determines thesetpoint within the limiter setpoints for the PI supply air temperature controller.Maximum Priority, coolingIf the value (0…10 V) of the input X2 is greater than the calculated output of the 3-point cooling sequence, the output will use the X2 input value as output value.The temperature setpoint X1 is shifted by the tem-perature as measured at sensor X2.Configuration of the RWD32 or RWD82 defines the influence on setpoint X1.The example shows the room air temperature set-point as controlled by the outside temperature.A digital switch or anlog input between terminals X2 and M can be used to implement win-ter/summer changeover.Digital changeoverWhen the contact is closed, summer operation is selected. Reverse acting output (Q1 only) is set to direct action (cooling).Analog changeoverWhen the X2 input exceeds the setpoint, summer operation is selected. Reverse acting output (Q1only) is set to direct action (cooling).A contact between terminals D1 and M can be used to implement setpoint changeover for day/night operation.When the contact is open, the setpoints for day operation are selected.When the contact is closed, the setpoints for night operation are selected.During the night mode, the following auxiliary func-tions are disabled: remote setpoint, abso-lute/Relative limiter, setpoint compensation andmaximum priority.Cascade control Maximum PrioritySetpoint compensationWinter/Summer operationDay/night setpoint6/11Mechanical design The RWD32 & the RWD82 universal controllers are as per DIN 43 880 Gr. 1 require-ments.A protective housing is used to protect the controller when mounted outside a control panel, such as on ducts, walls and in plant rooms. Furthermore, the protective housing prevents inadvertent contact with voltage supplying parts such as the connecting termi-nals.The RWD32 or RWD82 clips into the protective housing.The cable entries are located at the top and the bottom of the protective housing.The front has an opening for the LCD display and the programming buttons.The RWD32 and RWD82 universal controllers can be mounted as follows:• In a standard electrical control cabinet as per DIN 43 880• Wall mounted in a protective housing• Front mounting with standard available installation elementsPlug-in screw terminalsThe RWD32 and RWD82 are operated by the buttons on the controller front.

随着电网基础设施建设和电力能源投入的发展,电气成套设备需求量逐年增加,产品升级换代速度加快,生产设备及加工工艺有了明显改进、电气设备智能化、一二次融合技术、集成一体化等设备性能有了明显的提高。
一次设备是指直接用于生产、输送和分配电能的生产过程的高压电气设备。
它包括断路器、隔离开关、自动开关、刀闸开关、电缆母线、输电线路、电力电缆等。
由一次设备相互连接,构成配电设备开关或进行其分合闸操作过程的电气设备称为一次设备。
也称为无源组件。
二次设备是指对一次设备的工作进行监测、控制、调节、保护以及为运行、维护人员提供运行工况或生产指挥信号所需的低压电气设备。
由二次设备相互连接,构成对一次设备进行监测、控制、调节和保护的电气设备称为二次设备。
也称为有源组件。
一、二次设备融合关键技术
由于各种电器元件安装位置不同,在构成一个完整的电气控制系统时,就必须划分组件。
1、把功能类似的元件用模块化的形式组合在一起;
(1)尽可能减少组件之间的连线数量,同时把接线关系密切的控制电器置于同一组件中;
(2) 减少电压等级采用统一的供电电压
(3) 可把外形尺寸、功能相近的电器用模块的形式组合在一起;
(4)为了电气控制系统便于检查与调试,把需经常调节、维护和易损元件组合在一起。
2、在划分电气控制柜组件的同时要解决组件之间、电气箱之间以及电气箱与被控制装置之间的连线方式:
电气控制柜各部分及组件之间的接线方式一般应遵循以下原则:
(1)开关电器、控制板的进出线一般采用接线端头或接线鼻子连接,这可按电流大小及进出线数选用不同规格的接线端头或接线鼻子;
(2)电气柜、控制柜、柜(台)之间以及它们与被控制设备之间,采用接线端子排或工业联接。
