The control loop is made up of individual components which must be in permanent operation. The process variable to be controlled (controlled variable) is continuously measured and compared with the desired value (setpoint). The aim is to keep the controlled variable at the setpoint.The controlled variables (e.g. pressure, temperature, pH value, concentra-tion, ...) are measured using suitable sensors which provide the continuously measured values for comparison with the setpoint. The comparison intervals can be selected as desired. Deviations trigger a control procedure with the aim to adjust the controlled variable to the setpoint within a preset time.This comparison procedure and the calculation of the required change of the controlled variable is performed by the controller.Controllers are classified according to their characteristic, dynamic response, and mode of operation.CurveA distinction is made between continuous (linear) and discontinuous c ontrollers.Dynamic response:A change in the error variable at the controller input influences the m anipulated variable at the controller output.There is a great variety of classification criteria for linear controllers.Particular importance must be placed on their dynamic response, however. The following text describes the components of dynamic action and their typical combinations.••P Controller (Parameter: Controller Gain)The proportional-action component of a P controller transforms the control deviation (error variable) to a proportional controller output (manipulated variable). The range of the manipulated variable is limited. Therefore, also the usable range of the controller input signal (control range) is limited.Schematic Diagram of P ControllerTime response of control as reaction to a disturbance:After a short settling time a deviation x B remains.The desired value is not reached.I Controller (Parameter: Reset Time)The integral-action component takes account of the rate of change of the manipulated variable, i.e. it forms the time integral of the error variable. Each value of the controlled variable is assigned to a particular rate of change of the manipulated variable.P I ControllerThese controllers combine proportional and integral action. Compared toP controllers, which only provide a proportional relationship between con-trolled variable and manipulated variable, here an integration over time is also performed.First, the value of the manipulated variable is calculated in proportion to the error variable, and then the integral-action component is added.DControl (Parameter: Derivative)A derivative control alone is completely unsuitable since it only reacts to changes of the error variable, that is, constant errors remain unnoticed.PD ControllerThis controller adds the proportional change of the input signal and the rate of change of the controlled variable to the resulting manipulated variable.PID ControllerThis controller comprises the P , I, and D components of linear controllers. The manipulated variable of a PID control system is the sum of the output variables of a P, an I, and a D control system.The maximum overshoot of the PID controller is even smaller than that of the PD controller. Due to its I-action component there is no remaining offset. However, the components (P, I, D) of a PID controller implement a universally applicable, classical controller thanks to the fast reaction of the P compo-nent, the regulating capacity of the I component, and the attenuating effect of the D component.Typical ApplicationsP ControllerApplication for integrating control systems (e.g. closed tank, batchp rocesses).PI ControllerApplication for non-integrating control systems (e.g. drains).PID ControllerThe additional derivative action compensates for measurement peaks.C ontroller CharacteristicAnalog Controller IV1/IV2The following controller characteristics can be defined:Values are adjusted toward the setpoint.In the neutral zone (symmetrical to setpoint) no control takes place.Controller parameters: Controller gain, reset, and derivative.Feed time alarm: determines how long the controller output may be at maximum until an alarm is released. This allows recognition of a defective valve or an error in the process.Behavior during HOLD: User-defined Constant controller output (“last usablevalue”)Controller output = 0 (controller switched off)•••••P roportional Action (Gradient K C [%])10050 X w(CR: control range)C o n t r o l l erCR*0.2CR*0.4CR*0.6CR*0.8CRDeviationP ulse Length ControllerThe pulse length controller is used to operate a valve as an actuator.It switches the contact on for a time that depends on the controller output (Y). The period is constant. A minimum ON time of 0.5 sec is maintained even if the controller output takes corresponding values.Output signal (switching contact) of pulse length controllerPulse frequency (Y = 80 %)PID Controller and Limit Contacts ser-Defined VariablesUM enu SelectionAfter switching on, the analyzer performs an internal test routine and a utomatically detects the number and type of modules installed.

Read and follow all of Whelen’s written instructions when installing or using this device. Emergency vehicles are often operated under high speed stressful conditions which must be accounted for when installing all emergency warning devices. Controls should be placed within convenient reach of the operator so that he can operate the system without taking his eyes off the roadway. Emergency warning devices can require high electrical voltages and/or currents. Properly protect and use caution around live electrical connections.Grounding or shorting of electrical connections can cause high current arcing, which can cause personal injury and/or vehicle damage, including fire. Many electronic devices used in emergency vehicles can create or be affected by electromagnetic interference.Therefore, after installation of any electronic device it is necessary to test all electronic equipment simultaneously to insure that they operate free of interference from other components within the vehicle. Never power emergency warning equipment from the same circuit or share the same grounding circuit with radio communication equipment.All devices should be mounted in accordance with the manufacturer’s instructions and securely fastened to vehicle elements of sufficient strength to withstand the forces applied to the device. Driver and/or passenger air bags (SRS) will affect the way equipment should be mounted.This device should be mounted by permanent installation and within the zones specified by the vehicle manufacturer, if any.Any device mounted in the deployment area of an air bag will damage or reduce the effectiveness of the air bag and may damage or dislodge the device. Installer must be sure that this device, its mounting hardware and electrical supply wiring does not interfere with the air bag or the SRS wiring or sensors. Mounting the unit inside the vehicle by a method other than permanent installation is not recommended as unit may become dislodged during swerving; sudden braking or collision. Failure to follow instructions can result in personal injury. Whelen assumes no liability for any loss resulting from the use of this warning device. PROPER INSTALLATION COMBINED WITH OPERATOR TRAINING IN THE PROPER USE OF EMERGENCY WARNING DEVICES IS ESSENTIAL TO INSURE THE SAFETY OF EMERGENCY PERSONNEL AND THE PUBLIC.Warnings to UsersWhelen’s emergency vehicle warning devices are intended to alert other operators and pedestrians to the presence and operation of emergency vehicles and personnel. However, the use of this or any other Whelen emergency warning device does not guarantee that you will have the right-of-way or that other drivers and pedestrians will properly heed an emergency warning signal. Never assume you have the right-of-way. It is your responsibility to proceed safely before entering an intersection, driving against traffic, responding at a high rate of speed, or walking on or around traffic lanes. Emergency vehicle warning devices should be tested on a daily basis to ensure that they operate properly. When in actual use, the operator must ensure that both visual and audible warnings are not blocked by vehicle components (i.e.: open trunks or compartment doors), people, vehicles, or other obstructions. It is the user’s responsibility to understand and obey all laws regarding emergency warning devices.The user should be familiar with all applicable laws and regulations prior to the use of any emergency vehicle warning device. Whelen’s audible warning devices are designed to project sound in a forward direction away from the vehicle occupants. However, because sustained periodic exposure to loud sounds can cause hearing loss, all audible warning devices should be installed and operated in accordance with the standards established by the National Fire Protection Association.。

Make connections properly and make sure that a leak test is conducted before actual operation to prevent fluid from leaking into the atmosphere (Hereafter, the measured fluid is called “gas” or “fluid”).(2) DO NOT apply any fluids corrosive to materials exposed to gas. Corrosion may cause fluid to leak into the atmosphere. Check the gas type to be used in advance. (3)This device is not designed as an explosion proof structure. DO NOT use this device in a place where explosion-proof structures are required. Doing so may cause fire or explosion.Incorrect handling may lead to medium or slight injury or may cause damage to, or loss of, facilities or equipment(1) Observe the precautions listed in the WARNING (above)(2) Strictly observe the electrical specifications. Not doing so may cause fire, damage to sensors or malfunction.(3) This device is not designed to be waterproof. DO NOT locate this device outdoors or in a place where it may be splashed with water. Doing so may cause fire, trouble, or malfunction of the device.(4) DO NOT modify this device. It may cause fire or other problems.(5)This device is not designed to handle hot swap. Please avoid attaching and removing the power supply connector and interface connector with the power switched on. Attachment and/or removal with the power on may result in failure of the device.(6) While a power supply is applied to MFC, ±15VDC must be applied simultaneously. If only +15VDC or -15VDC is applied, electronic circuits will become unstable and it may cause a malfunction of MFC.(7) This device is a precious device, please handle it carefully. Dropping down or handling it carelessly will cause damage. Please use assist instrument while moving or setting the device.(8)Regular maintenance is recommended for steady use of this device (Recommended proofreading frequency is once a year).1. IntroductionThis manual explains basic operation of the MC-700 series (Hereafter, it is called"MFC"). Please read through this manual and other separate volumes (Digital Interface Manual, Special Function Manual, Command Chart) carefully to familiarize yourself with the features of this device.2. SummaryThis device is the mass flow controller with the function of switching differentkinds of gas and flow rate (Hereafter called "variable function" or "VR"). By using the 3 rotary switches on the MFC, the gas type and flow rate can be changed. The rotary switches are placed conveniently on top of the MFC unit so thatadjustments can be made accordingly even after the unit is set in position. For old models, stocking MFC for each of gas and flowrate was necessary because only one spec is available to one MFC, and MC-700 can reduce your stocking because it can be used for more than one spec with one MFC.3. FeaturesThe MFC has the following features.(1) LINTEC’s proprietary ambient temperature compensation type flow sensor.·The influence of ambient temperature is small due to the sensor temperature control following the ambient temperature.·Since the temperature distribution of the sensor is constant, high-speed response is possible.(2) Gas type and flow rate setting can be changed by using the 3 switches on the mass flow controller unit.(3) Digital interface (RS-485) is standard equipment and the maximum of 32 MFCs could be connected together with daisy chain. (Option: Digital interface RS-232C is possible)(4) Small structure of dead volume using diaphragm valve.(5) Stainless steel 316L is used because of good corrosion resistance and seal ability. (6) Particule-free structure(7) RoHS compliant, CE conformity4. StructureThe MFC consists of sensors, bypass, valves, and a microcomputer for signalprocessing. A digital PID feedback control system controls the valve action so that flow rate output from the sensor agrees with flow rate setting value.5. Specification / DimensionsNote 2) The value at the time of shipping. This may change with gas type and flow rate setting. · Connect the MFC to the ground.(2) Dimensions6.

Connection(1) Analog interface connectorMounted connector : D-Sub 9 pin(male)Note4)Pin No.[4],[7]and No.[8] are connected internally in MFC.Wirings should be done as shown below in order to remove the effect of potential difference among the COMMON.Do not connect. Flow rate setting signal COMMON[8], Flow rate output signal[7], and Power supply COMMON[4] in the power supply unit.(2) Digital interface connectorMounted connector : RJ-45 Modular jack Pair connector : RJ-45 Modular plugR0 or R1. Refer to the attached sheet of digital interface instruction manual for connection. Note6)[Power OUT] means the power output of RS-1 interface and it is not applicable for connections to other machines without R1 option.· RS-1 is a discontinued product. Therefore, MC-3000E series / MC-2000 series can be replaced with MC-700 series including option.8. Alarm functionsThe MFC has two types of alarm functions built in. In addition, alarm status can be confirmed using both digital communication (alarm output from the digital connector) and an LED located on top of the body of the MFC. As alarm settings can only be changed using digital communication, please carry out necessary changes using this method. For 9. Software switch (factory shipped value)This MFC is provided with a software switch for operation mode setting. Beforeoperation, input the necessary data for various functions by using the digital interface.· If the zero adjust button on the top of the MFC is pressed and held for over 5 seconds, the communication protocol is reset to default.10. Operation (1) Procedure1)This product is packed in a clean room before shipment. Please break theseals in a clean room after taking it out of its box.2) Check the gas type and flow rate and check the direction of the gas flow and the MFC before installation.3) Check for gas leaks from the tubing with a helium (He) leak detector. 4) Connect the interface connectors according to the Connector table.5) Power requirements are +15VDC:120mA and -15VDC: 50mA. Check the voltage, polarity, and capacitance of the power supply voltage.6) Turn on power supply and let the equipment warm up for at least 5 minutes (Recommended time: 30min).7)Adjust the zero point by pressing the zero adjustment, switch located on the top of the MFC. Before zero-point adjustment, check that gas is not being supplied and the device was warmed up for 30 minutes or more in order to ensure sensor stability.8)Input the flow rate setting signal and supply gas with required differential pressure to the MFC. The MFC will begin to control the gas flow in proportion to the preset voltage. Full-scale voltage is 5VDC. Maximum input voltage is ±15.5VDC.9) When the output flow rate signal is used, the tolerance voltage of the external device should be more than ±15.5VDC. When it’s conne cted the output valve may be within the range of the maximum voltage ±15.5VDC. 10) Complete shut-off cannot be achieved with the mass flow controller. If complete shut-off is desired, a shut-off valve should be installed.11) When a highly reactive gas is used, thoroughly purge all foreign matter from the tubing and the MFC before operation.12) When contaminated gas is used, install a filter at the equipment inlet.13)Use the MFC within the range of the operating temperature (15 to 35°C), and keep it at the same temperature with the gas. If used in any environment that does not meet the above-mentioned requirements, the flow rate cannot be measured accurately and the device may fail.14)Do not switch the power supply on and off within one second. It may cause failure.(2) Valve control signalThe MFC features a forced valve open/close input function.The connector pin No.1 is used to input the internal valve open/close signal. By inputting this signal, a forced opening/closing of the internal valve can be performed without depending on the value of the flow rate preset signal. When +15VDC is input: fully open When –15VDC is input: fully closed(3) Variable Range functionBy using one device of MFC, it is possible to modify multiple flow rate ranges and gas types. To modify the flow rate or the gas type, refer to the following VR corresponding chart or the calculation formula, and modify the variable range by the rotary switches (for analog control) or digital communications (for digitalcontrol).[Formula](standard flow rate) ÷ (desired flow rate) × (conversion factor) By using this function, the flow rate and gas type may be changed, however if a different gas is to be used, please consider the properties of the gas and confirm the responsiveness before usage. Also, in the case that the gas may cause debris or particle, please refrain from using it. If you have any questions of conversion factor, please contact us.(4) Digital interfaceThe MFC features the RS-485 or RS-232C (Note 5) digital interfaces. Manyspecial functions can be employed using the digital interfaces.Please refer to other manuals (Digital Interface Manual, Special FunctionManual Command Chart).11.

如果开投影机的时候幕布不下来就将电位器往“-”方向轻微旋动，如果关投影机的时候幕布不上去就将电位器往“+”方向轻微旋动；(联动：指投影机开机时幕布会自动下降,投影机关机时幕布会自动上升.通过检测投影机工作电流来实现)；VGA输入：有4个VGA口输入，从左到右分别为0、3、2、1口，可以切换到投影VGA口输出VGA输出：一路接显示器，一个接投影机，显示器的只能输出电脑口的，投影机的可以通过切换来输出4个中的任一个，如果是数码中控，则可以输出视频转换后的信号视频输入：4路视频输入，如果型号带有线电视的，则是3路视频输入，一路电视信号输入，从左到右分别是0、1、2、3口视频输出：4路输入可以切换一路输出到投影机的视频，如果是带电视可以输出电视视频信号话筒输入：2路话筒输入，有线咪的放大倍数小点，无线咪放大大些音频输入：4路立体声输入，，立体声切换左右声道同时切换，不会也不能分开，从左到右是0、1、2、3口音频输出：立体声输出，4路选1路输出，音量可调红外控制：4路红外控制口，一个立体声头有2个红外发射灯是2路红外控制，两灯都是发同样的码，另外一个立体声头也是一样弱电输出：用来接电子锁和供12V电的，左向右为+12V 地锁，电子锁正极接“锁”，负极接“地”，12V是个双向的，可以有12V输出，若开锁电流大于500mA，则要在+12V 接入12V电源，否则容易造成中控CPU电变化大而死机，电子锁和输入或作输出12V都是共一个地。
注意：最大12V电流输出不能超过1.5ACOM1口接电脑串口和投影机232口，COM2口是接面板或者扩展模块的，NET/485是用来接网线做网络控制用的，其中也有安防口，只有网络模块才有这些防区的，IP电话是用来接IP电话手柄的插口，安防I/O是用来接电脑开关门磁安防等COM1，COM2，NET/485，IP电话，安防I/O和S端子接口引脚定义如下：COM1 COM2 NET IP电话安防I/O S端子/色差1 RXD2 十5V网络用1听筒门磁Y2 RXD1 TXD1 网络用2话筒防区3 C3 TXD1 RXD2 网络用3振铃防区4GND4 TXD2 开键GND 挂断电脑开REVERSE5 GND GND 防区5地地 C6 RXD3 GND 网络用6地防区1Y7 TXD3 开有5V防区4十5V防区2CR8 NC 12V/NC防区3十12V电脑开CB图中为孔从中控后面看，直接看也可以看出来4、5脚离的远，3、4靠的近上图RJ45的弹片在下方COM1是用来与电脑通讯和控制投影机的，将中控主机与电脑的通讯线圆口一头插入中控的COM1口，注意接口方向(有箭头标志的在上面)，另一头九孔插头接在电脑主机的串口，并确定将其插好。
在靠电脑串口旁有一根露出的单芯屏蔽线，此线为中控与投影机串口线，此线屏蔽线接投影机串口的“GND”端，芯线接投影机串口的“信号接收端”。
控制面板和控制主机用RJ45网线连接，一头接中控机通讯口COM2，另一头接控制面板COM1（COM2、COM3都可）。
投影机控制可选择红外控制，红外控制请将配件中的红外控制线适量延长后，一头接在中控主机的红外控制的投影机口，另一头放在投影机的红外口接收处,可以将整个红外头用黑胶布粘遮掩已防干扰。
其他的红外控制也一样。
其它接线可参考中控主机后的接口指示安装即可，若有不明可与工程师联系。
三、系统设置系统许多功能可设定修改，满足各种场合和各种用户的不同需求。
系统可设定的功能有开机状态、开关机流程、开关延时、投影机控制、面板按键功能等。
这些功能的设置通过电脑软件来完成，需首先安装相应的电脑设置软件，连接控制主机和电脑的通讯电缆，才能进行各种功能设置。
