丹佛斯车载压缩机驱动器接线定义一、开场白嘿，朋友们！你有没有想过，我们日常乘坐的汽车中，有一个看似不起眼但却至关重要的部件——丹佛斯车载压缩机驱动器？这其中涉及到一个关键的概念，那就是接线定义。

就好比我们家里的电器需要正确接线才能正常工作一样，丹佛斯车载压缩机驱动器的接线也是有严格规定的。

那到底这接线定义是怎么一回事呢？今天咱们就来好好聊聊。

二、什么是丹佛斯车载压缩机驱动器接线定义？简单来说呀，丹佛斯车载压缩机驱动器接线定义就是规定了这个驱动器各个接线端口与外部线路连接的方式和规则。

比如说，咱们开车的时候，空调系统要正常运行，压缩机就得稳定工作，而这就依赖于驱动器的正确接线。

常见的一个误区就是，有人觉得接线随便接接就行。

其实不是这样的哦！在汽车的电气系统中，要确保每个部件都能协同工作，接线必须精准无误。

所以呢，只有按照规定的接线定义进行连接，丹佛斯车载压缩机驱动器才能正常发挥作用，保障汽车空调系统的稳定运行。

三、关键点解析3.1 核心特征或要素首先呢，接线端口的标识是一个重要的要素。

不同的端口有着特定的功能，比如电源输入端口、信号控制端口等等。

就像我们的手机充电接口，插错了可就充不了电。

丹佛斯车载压缩机驱动器的接线端口也一样，如果接错了，可能会导致驱动器无法正常启动，甚至损坏设备。

其次就是接线的类型和规格啦。

这可不是随便选的，要根据电流、电压等参数来确定。

就像我们建房子选钢材，得选能承受相应压力的规格，接线也是如此。

比如，某些高功率的线路就需要粗一些的导线，以保证电流的稳定传输。

最后就是接线的顺序和方法。

这就需要严格按照厂家的说明来操作。

比如说在连接多个线路时，先接哪根后接哪根都有讲究。

就像组装家具，步骤错了可能就装不起来。

只有按照正确的顺序和方法接线，才能确保丹佛斯车载压缩机驱动器正常工作。

3.2 容易混淆的概念丹佛斯车载压缩机驱动器接线定义很容易和普通电气接线混淆。

普通电气接线可能相对简单，要求没那么严格。

It is used with a solenoid valve in the liquid line.TQ valveThe controller can also control a TQ type valve. This valve has been discontinued from the product range, but the settings are still described in this manual.AKV is a pulsating valve.Where the AKV valve is used it also functions as solenoid valve.Temperature control is performed based on a signal from tem-perature sensor S3 which is placed in the air current before the evaporator. Temperature control is in the shape of an ON/OFFthermostat that shuts off the liquid flow in the liquid line.User Guide | Superheat controller, EKC 315A© Danfoss | DCS (ADAP-KOOL®) | 2015-03DKRCI.PS.RP0.D2.02 | 520H7653| 3OperationSuperheat functionYou may choose between two kinds of superheat, either:• Adaptive superheat or • Load-defined superheatMOPThe MOP function limits the valve’s opening degree as long as the evaporating pressure is higher than the set MOP value.Override functionVia the analog input a displacement can be made of the tempera-ture reference or of the superheat reference. The signal can either be a 0-20 mA signal or a 4-20 mA signal. The reference can be displaced in positive or negative direction.External start/stop of regulationThe controller can be started and stopped externally via a contact function connected to input terminals 1 and 2. Regulation is stopped when the connection is interrupted. The function must be used when the compressor is stopped. The controller then closes the solenoid valve so that the evaporator is not charged with refrigerant.RelaysThe relay for the solenoid valve will operate when refrigeration is required. The relay for the alarm function works in such a way that the contact is cut-in in alarm situations and when the controller is de-energised.Modulating/pulsating expansion valveIn 1:1 systems (one evaporator, one compressor and one condens-er) with small refrigerant charge ICM is recommended.In a system with an AKV valve the capacity can be distributed by up to three valves if slave modules are mounted. The controller will displace the opening time of the AKV valves, so that they will not pulsate at the same time.Used as slave module is a controller of the type EKC 347.Analog outputThe controller is provided with an analog current output which can be set to either 0-20 mA or 4-20 mA. The signal will either fol-low the superheat, opening degree of the valve or the air tem-perature.When an ICM valve is in use, the signal is used for control of the valve via the ICAD actuator.PC operationThe controller can be provided with data communication so that it can be connected to other products in the range of ADAP-KOOL® refrigeration controls. In this way operation, monitoring and data collection can be performed from one PC – either on the spot or ina service company.User Guide | Superheat controller, EKC 315ASurvey of functions© Danfoss | DCS (ADAP-KOOL®) | 2015-03DKRCI.PS.RP0.D2.02 | 520H7653 | 4User Guide | Superheat controller, EKC 315A © Danfoss | DCS (ADAP-KOOL®) | 2015-03DKRCI.PS.RP0.D2.02 | 520H7653| 5User Guide | Superheat controller, EKC 315A © Danfoss | DCS (ADAP-KOOL®) | 2015-03DKRCI.PS.RP0.D2.02 | 520H7653 | 6User Guide | Superheat controller, EKC 315A© Danfoss | DCS (ADAP-KOOL®) | 2015-03DKRCI.PS.RP0.D2.02 | 520H7653| 7User Guide | Superheat controller, EKC 315A© Danfoss | DCS (ADAP-KOOL®) | 2015-03DKRCI.PS.RP0.D2.02 | 520H7653 | 8There are LED’s on the front panel which will light up when the belonging relay is activated.The upper LED will indicate the valve’s opening degree.

However, a wrong installation, for example, could still present problems. Electronic controls are no substitute for normal, good engineering practice.Danfoss wil not be responsible for any goods, or plant compo-nents, damaged as a result of the above defects. It is the installer's responsibility to check the installation thoroughly, and to fit the necessary safety devices.Particular attention is drawn to the need for a “force closing” signal to controllers in the event of compressor stoppage, and to the requirement for suction line accumulators.Your local Danfoss agent will be pleased to assist with further advice, etc.Appendix 1Interaction between internal and external start/stop functions and active functions.Appendix 2Cable length for the TQ actuatorThe actuator must be supplied with 24 V a.c. ± 10%.To avoid excessive voltage loss in the cable to the actuator, use a thicker cable for large distances.Wire cross sectionCable lengthInternal Start/stop Off Off On On External Start/stop (DI)Off On Off On Refrigeration (DO2)Off OnTQ actuatorStandbytemperatureRegulatingExpansion valve relay Off On Temperature monitoring No Yes Sensor monitoring Yes Yes ICM Closed RegulatingThe two types of regulation for superheat are, as follows:Adaptive superheatRegulation is here based on the evaporator’s load by means of MSS search (MSS = lowest permissible superheat).(The superheat reference is lowered to the exact point where instability sets in).The superheat is limited by the settings for min.and max.super-heat.Load-defined superheatThe reference follows a defined curve.This curve is defined by three values: the closing value, the min. value and the max. value. These three values must be selected in such a way that the curve is situated between the MSS curve and the curve for average temperature difference ∆Tm (temperature difference between media temperature and evaporating temperature.Setting example = 4, 6 and 10 K).Start of controllerWhen the electric wires have been connected to the controller, the following points have to be attended to before the regulation starts:1. Switch off the external ON/OFF switch that starts and stops the regulation.2. Follow the menu survey on page 8, and set the various para-meters to the required values.3. Switch on the external switch, and regulation will start.If the superheating fluctuatesWhen the refrigerating system has been made to work steadily, the controller’s factory-set control parameters should in most cases provide a stable and relatively fast regulating system.If the system however fluctuates this may be due to the fact that too low superheat parameters have been selected:If adaptive superheat has been selected:Adjust: n09, n10 and n18.If load-defined superheat has been selected:Adjust: n09, n10 and n22.Alternatively it may be due to the fact that the set regulation parameters are not optimal.If the time of oscillation is longer than the integration time:(Tp> Tn, (Tnis, say, 240 seconds))1. Increase Tnto 1.2 times Tp2. Wait until the system is in balance again3. If there is still oscillation, reduce Kpby, say, 20%4. Wait until the system is in balance5. If it continues to oscillate, repeat 3 and 4If the time of oscillation is shorter than the integration time:(Tp< Tn, (Tnis, say, 240 seconds))1. Reduce Kpby, say, 20% of the scale reading2. Wait until the system is in balance3. If it continues to oscillate, repeat 1 and 2.4. Follow the actual room temperature or superheat on the display.(On terminals 2 and 5 a current signal can be transmitted which represents the display view. Connect a data collection unit, if applicable, so that the temperature performance can be followed).If the superheat has excessive underswing during start-upIf you regulate with valve type ICM or AKV:Adjust n22 a little bit up and/or n04 a little bit down.If you regulate with valve type TQ:Adjust n26 a littlle bit downList of literatureInstructions RI8GT (extract from this manual).Here you can see how controllers are mounted and programmed.Installation guide for extended operation RC8ACHere you can see how a data communication connection to ADAP-KOOL® Refrigeration control systems can be estab-lished.Danfoss can accept no responsibility for possible errors in catalogues, brochures and other printed material.
