JF-M11安装使用说明

JF-M11双监视模块安装使用说明一、简介：JF-M11双监视模块是在JF-M01监视模块基础上开发的。

它与JF998火灾报警联动控制系统配套使用，挂接在JF998的二总线上，只用一个模块的位置，但相当于两个M01监视模块，可用于两个被监视设备距离较近的情况。

可以降低成本，节约工程造价。

二、特点：l 无极性二总线，可与JF-998报警控制器的二总线以任意极性并接。

l 电子编码，无拨码开关。

编码值可用控制器或编码器在现场设定l 一个模块相当于两个M01，在总线上占两个相邻的探测地址。

每个地址都可分别监视一对开关输入。

三、主要技术指标：1.工作电压：DC24V±3V2.工作电流：∽400μA3. 环境温度：（0∼50）℃（RH≤95%）4.输入方式：无源常开触点四、编址：该模块在总线上占两个相邻的探测地址，分别对应于本模块的第一和第二两个单元。

用控制器或编码器只对第一个地址编码。

用控制器编码的方法与探测器编码方法相同。

首先，模块要在离线状态，使控制器进入编址菜单，编址的地址范围是001至191 （如果是在非混编系统中使用，则只能在1-126范围编码）。

然后把要编码的模块接入正在编码的二总线回路，待控制器提示该地址编址完成后，模块就编址好了。

五、指示灯：正常工作状态，两个红灯微闪。

每个红灯分别对应一路输入信号的状态。

左边的灯对应第一路输入，右边的灯对应第二路输入。

当任一路有短路信号时，对应的灯则开始间歇强亮，短路消除后恢复微闪。

六、接线：底座接线图如下：L1、L2连接二总线。

A1、A1’为第一单元的输入。

A2、A2’为第二单元的输入。

JF-M04总线隔离模块

JF-M04总线隔离模块接入回路二总线主干线与支线的交界处，起到隔离保护各支线的作用；或者串接到回路二总线的各段，起到分段保护的作用。

当M04后段的总线发生短路故障时，该模块将其后段的部分断开，以保护报警主机和系统中的其余部分仍正常工作（通向JF－998主机的一端为前段，通向探测器、模块的一端为后段），对被隔离部分的编址单元，报警主机将报出故障信号，当总线短路故障排除后，M04能自动恢复全线正常通讯，M04不占任何地址点位。

JF-M04总线隔离模块主要特点及技术指标：→输入输出均无极性；→无编码，不占用总线地址；→内置CPU，能自动判断回路二总线的状态，隔离更可靠、更安全；→对回路二总线的供电和信号没有插入损耗；→低功耗，由回路二总线供电；→采用噪音滤波，保障总线通讯稳定可靠；→插拨式端子结构，安装维护方便；→工作电压：21VDC～28VDC（由回路总线提供）；→隔离动作时间：< 30ms；→恢复时间：< 30ms；→保护容量：推荐为≤50编址单元，（M04允许更多的编址单元使用一只M04，但当M04后段回路二总线短路时会使M04后段的全部编址单元被隔离，工程应用中应充分注意）；→使用环境：温度：0℃～50℃相对湿度：≤95％RH（40℃±2℃）；→外形尺寸：同JF-M01。

外接线端子：→M04的结构与M01相同，其接线端子如下：→15（L1）、16（L2）-回路二总线（前段）接入；→7（L1-1）、8（L2-1）-回路二总线（后段）接出；安装：M04为插拔式结构，其底座安装于86H50预埋盒上，安装方式与M01同。

【应用图示】：可安装在竖井内，接入楼层平面回路二总线分支处或者串联到楼层平面回路二总线之中。

说明：* 当1～10号编址单元所接的回路二总线段出现短路，1号M04将动作，从而使整个1层的全部探测器、模块等编址单元被隔离；* 当11～20号编址单元所接的回路二总线段出现短路，3号M04将动作，从而使11～20号探测器、模块等编址单元以及31～40号探测器、模块等编址单元被隔离；* 当31～40号编址单元所接的回路二总线段出现短路，4号M04将动作，从而仅仅使31～40号探测器、模块等编址单元被隔离。

145故障隔离(FIM)使用介绍

FAULT ISOLATION MANUAL USAGE 1.General A.This section provides information on how to use the Fault Isolation Manual to isolate and correct the faults that may occur on the aircraft.It also gives the terms,definitions,and recommended mainte-nance practices for performing troubleshooting.B.This section also gives the path from the aircraft faults to the fault isolation tasks.However,it does not focus on giving definitions and detailed explanations of the structure of the manual or fault categories.You can find this information in the introduction to the FIM (FIM INTRODUCTION).For a better understanding,we recommend that you read the introduction to the FIM before you read this section any further.C.The instructions contained in this section are intended to be used mainly by the ground crew.The flight crew and flight attendants should refer to the Introduction to the Fault Reporting Section (FIM FAULT REPORTING SECTION INTRODUCTION).D.(2)events,recordedon the CMC).(3)(4)on the CMC.2.crew identify faults based on logbook entries or other evidence.The flight crew and flight attendants may also use the Fault Reporting Section to speed up the faults to the ground crew.B.and the appropriate fault code assigned to it,the ground crew fault isolation task contained in the Fault Isolation Section of this FIM.C.To find the appropriate fault isolation task in the Fault Isolation Manual,you should follow these describing the fault and determine the system experiencing the fault.If necessary,go to the Fault Report section to identify the appropriate fault code.For EICAS messages and observed faults,the first two digits of code define the system.For cabin faults,the letter defines the system (Figure 1)(Figure 2).(2)If the pilot logbook report does not allow direct determination of the fault code,the technician should,by performing some observation and preliminary checks,define the fault that best matches the situation and then find the fault code (Figure 1)(Figure 2).(3)With the fault code number,enter in the Fault Code Index to determine the task reference for MANUALfault isolation.In the case of the fault displayed as an EICAS message,first determine if there is any maintenance message related to the fault (Figure 3).This is indicated in the mainte-nance messages field.Check the CMC to determine the correct fault isolation task,as applicable (Figure 4).MANUALHow to Use FIM Figure 1MANUALEM145FIM000104A.DGNIF YOU HAVE THEN DO THIS TO FIND THE FIM TASKHow to Find a Fault Isolation TaskFigure 2MANUALMANUALFigure3MANUALFigure43.How to Perform a Fault Isolation Manual Task A.Read the General topic carefully to make sure that the fault that is present in the aircraft is really covered by this fault isolation task.The General topic gives general information about the task,including the fault codes (Figure 5).B.Read the Fault Description topic to learn about the fault and the conditions in which the fault has occurred (Figure 5).C.The Probable Causes topic provides a listing of the possible causes of the fault,sorted from the most probable and accessible to the least probable and accessible items.For easy reference,aircraft LRUs on this list have IPC and AMM removal/installation references.When an electrical harness is a probable cause,there will be a reference to the applicable WM section (Figure 5).D.Do all steps in the Initial Evaluation topic to confirm the fault and/or to make additional checks prior to performing the actual fault isolation procedure (Figure 5).E.that,before performing

4below.MANUALEM145FIM000101A.DGNFault Isolation TaskFigure 5MANUAL4.Fault Isolation Philosophy,Terms Used,and RecommendedMaintenance Practices A.The procedures in this FIM have not been prepared to cover intermittent faults.However,if an intermittent fault occurs,a corresponding troubleshooting procedure should be looked for in this publication and the malfunction troubleshooted,but only if the airline’s policies for intermittent faults allow it.If the fault cannot be solved,the EMBRAER Technical Support Department should be consulted.B.In the Probable Causes section,the ″Transitory condition of ″statement indicates an LRU fault that has been solved by means of a reset of the LRU or by the accomplishment of an operational or functional test on that LRU.The ″Failure of ″statement indicates an LRU fault that has been solved by the replacement of that LRU.C.The procedures in this FIM are given in two formats:block diagram or plain text.The vast majority of FIM tasks are in a block diagram format (Figure 6).Those tasks which have only one probable cause or those tasks which refer to the component manufacturer manual are presented in plain text format (Figure 7).D.For the FIM tasks in block diagram format,each block contains a test description and/or a question.After each question,there will be two possible answers:″Yes ″or ″No ″.The sequence determined by the answer of each test will lead to the path to isolate and correct the fault.Refer to Figure 6.E.To answer ″Yes ″to the ″Is the fault removed?″question,it is necessary to make sure that the root condition that led to the fault isolation task being performed has been eliminated.This can be understood as:•An EICAS message going out of view.•An observed fault or cabin fault condition being eliminated.If necessary,additional information to make sure that the fault has been removed will be given,either in the pageblock General topic (when applicable to the entire pageblock),in the task General topic,or even within the task itself.F.There is a number in the upper left corner of each block.That number is used for reference only.It does not indicate the sequence in which the tests should be made (Figure 6).G.The blocks with thicker borders indicate either that you have reached the end of the procedure (by solving the problem)or that the troubleshooting procedure continues in another FIM task (Figure 6).H.The ″End of troubleshooting ″statement indicates that you have reached the end of the procedure (by solving the problem).Therefore,you must stop the fault isolation at this point,no matter what stage of the task you are at (Figure 6).I.Electrical checks are a common practice in fault isolation procedures.In this FIM,there are two possible formats for presenting electrical checks:unnumbered lists inside a block in the Fault Isolation Procedures topic or electrical check tables in the Complementary Tables topic.J.The unnumbered list format is used when the required electrical check is short enough to fit inside a block of the fault isolation procedure.For an example of electrical check in the unnumbered list format,refer to Figure 6.K.The electrical check table is the standard format for electrical checks.It is always preceded by a Wiring Manual reference to support the check.Here is an example of a hypothetical electrical check table:Table 1-Electrical Check Table ExampleFROM TO MEASURE EXPECTEDP0123-3P1198-C CONTINUITY SHORTP0123-5GROUND CONTINUITY OPENP1155-A-1P1155-C VOLTAGE 28VDC•The FROM and TO columns give the connector identification and the pins that must be used in the check.The information before the dash is the connector identification and the information after the dash is the pin identification.In some cases the pin identification also has dashes.In this case,everything after the first dash is considered as related to the pin identification.•The kind of electrical test is given in the MEASURE column and is limited to:CONTINUITY ,VOLTAGE,CURRENT,and RESISTANCE.•The value or condition expected from the item under test is given in the EXPECTED column.For RESISTANCE,VOLTAGE,and CURRENT measurements,a value,along with the tolerance (if applicable)and measuring unit,is provided.For CONTINUITY checks,an OPEN or a SHORT condition is provided.•Continuity checks are given based on the necessary end-to-end points.In some cases the continuity check may require wire jumpers or shorts-to-ground checks when the connectors are physically far from each other.The airline technician can use any alternative method for continuity checks at his discretion.Always make sure that there are no units connected to the wiring harness while performing continuity checks.This is to avoid interference and/or damage to LRUs due to high voltage/ohm metering.When checking a wire for continuity from one connector to another,also check if it is not shorted to the aircraft ground.•For VOLTAGE and CURRENT checks,it is assumed that the positive lead (red)of the multimeter is on the pin listed in the FROM column and that the negative lead (black)of the multimeter is on the pin listed in the TO column.•You can only answer ″Yes ″to the ″Did the electrical check pass?″question if all tests,in all rows of the electrical check,have satisfied the conditions given.Otherwise,you should answer ″No ″and do the recommended steps to be followed.•Some electrical checks may also give you additional references if a special tool,implement,or GSE is required for access to the check points.Refer to the references given for a safe and correct operation of the tool,implement,or GSE.L.All electrical checks in this FIM can be performed with a standard hand multimeter,unless otherwise specified.M.Whenever the FIM requires the accomplishment of a DC-voltage measurement and the expected result is 24or 28volts,any value between 22and 29volts is acceptable,unless otherwise stated in the task being carried out.N.If an electrical harness repair is necessary,a reference to the ATA numbers of the applicableMANUALdiagrams of the WM will be given.For repairs on harnesses,strictly follow the instructions given in WM20-21-00(Wiring Repairs-Maintenance Practices).Also,make sure that all the circuits involved with this harness are de-energized or disconnected when repairing a harness.If not possible at all, isolate the harness from the involved LRUs or repair the harness outside the aircraft.ponent replacement terminology:NOTE:The operator can,at his discretion,use alternative replacement procedures or policies that have already been approved and are in use by the airline.These alternative replacementprocedures include experimental replacement of parts,use of parts obtained from an aircrafton different aircraft of the same fleet,interchange of equivalent parts of the same aircraft,etc.Therefore,the operator must undertake responsibility for all applicable precautions,suchas software reloading and equivalency.The items that follow are Embraer recommendationsfor component replacement.•The MPP references for removing and installing the components are always provided in the fault isolation task,in the form of a reference to the removal/installation pageblock.E.g.:″Replace Integrated Computer2(AMM MPP31-42-01/401)″.•If the fault isolation procedure asks you to″replace″the component,then remove the specified component and install a new unit from the stock.•If the fault isolation procedure asks you to″install[the component]again″,then install the same component that you have previously removed.•Some tasks ask you to remove the component for a harness check or any other check.If subsequent steps tell you to″replace″or″install a new″component,then install a new component from the stock.P.If a circuit breaker is open before or during troubleshooting,never force-close this circuit breaker.You must first determine and remedy the discrepancy that caused the circuit breaker to trip.Circuit breakers are devices designed to protect the electrical wiring from overcurrent and,therefore,avoid the danger of electrical overheat and fire.Q.References within a fault isolation procedure:•When the expression″TO PAGE XXX,BLOCK YY″is used,you must perform steps starting at BLOCK YY in the PAGE XXX and continue from there on,doing all subsequent steps.•When the expression″Do the respective troubleshooting(FIM TASK XX-YY-00-ZZZ-WWW-A)″is used,you must continue your troubleshooting by doing FIM TASK XX-YY-00-ZZZ-WWW-A and continue from there on.•When the expression″Refer to...″is used,it means that some support material is provided.It can be a reference to a table,to the Task Supporting Data pageblock,to a graph,to an MPP task,etc.EM145FIM000102A.DGN Fault Isolation Task-Fault Isolation Procedures Section(Block Diagram Format)Figure6EM145FIM000107B.DGN Fault Isolation Task-Fault Isolation Procedures Section(Plain Text Format)Figure7A.In the Task Supporting Data section of each CHAPTER-SUBJECT pageblock are logic diagrams forEICAS and CMC messages.They can be a valuable aid for the aircraft maintenance technicians.The logic diagrams show the conditions that make the EICAS or CMC messages to be displayed.NOTE:The″Internal Logic″statement may appear to some EICAS messages without logic dia-grams.This statement suggests that a replacement of the LRU indicated on that EICASmessage should cause the EICAS message to disappear.B.An example of a logic diagram of an EICAS message is shown in Figure8.C.The symbols used on these logic diagrams are shown in Figure9.NOTE:The″Aircraft ID Config″input that appears in some logic diagrams refers to the aircraft identity straps configuration(WM34-90-01).D.Some tips can make the analysis of the logic diagrams easier:(1)Initially,read the diagram from right to left.Identify the rightmost gate.In most cases,there willbe two possibilities:an AND gate or an OR gate.(2)If the rightmost gate is an AND gate,identify its inputs.The simpler inputs can be named as“ENABLE”conditions to cause the EICAS or CMC message to appear.The remaining inputscan be named as“TRIGGER”conditions to cause the EICAS or CMC message to appear.(3)If the rightmost gate is an OR gate,all the inputs can be named as“TRIGGER”conditions.(4)Analyze each of the“TRIGGER”conditions.E.The following example will illustrate these tips.The message“ICE CONDITION INOP”(EICAS caution message)indicates that the aircraft cannot meet the basic design function of providing airframe anti-ice ability.(1)Reading the logic diagram from right to left,we identify the rightmost gate:it is an AND gate.Ithas three direct inputs.(2)Two direct inputs are simpler than the other one.They can be named as“ENABLE”conditions.The first“ENABLE”condition is shown in Detail A(Figure10).In this picture,Selected DAU1isthe SOURCE of the Ice Condition INPUT.The Ice Condition INPUT is‘true’when it has the‘ice’STATUS.The same happens with the second input(SOURCE=Selected DAU2;INPUT=IceCondition;STATUS=‘ice’).Therefore,the output is‘true’if either of the Ice Detector inputsignals is‘ice’(‘true’).The second“ENABLE”condition is shown in Detail B(Figure10).In this case,the output is‘true’if both Air Starter Valves are actually closed OR both‘Engine Start Request’signals arenot active.(3)Once these“ENABLE”conditions are met,any of the following“TRIGGER”inputs maycomplete the expression and cause the EICAS message“ICE CONDITION INOP”to appear.The first“TRIGGER”input is shown in Detail C(Figure10).In this case,the output is‘true’if either the ADC altitude value is less than23000feet AND the Stabilizer A/I valve equals open AND the stabilizer low-pressure switch equals low pressure.The second“TRIGGER”input is shown in Detail D(Figure10).In this case,the output is‘true’if the Stabilizer A/I valve position is closed.(4)The analysis should continue this way.E M 145F I M 300018A .DG NI P M 69 F I G U R E #2 O U T P U

"true" for the output to be "true". In all other conditions, the output is "false".All inputs must be "false" for the output to be "false". In all other conditions, the output is "true".If the input is "true", the output is "false" and vice−versa.The inputs may change according to the switch position.If the input becomes "true", it has to remain "true" for at least the time displayed on the block before the output becomes "true".If the input becomes "true",the output will remain "true"for the time displayed in the block and, after that time,will become "false".Logic Diagrams SymbologyFigure 9SELECTED DAU1 ICE CONDITION = ICESELECTED DAU2 ICE CONDITION = ICEDETAIL ASELECTED DAU2 AIR STARTER VALVE LEFT = CLOSED SELECTED DAU2 AIR STARTER VALVE RIGHT = CLOSED SELECTED DAU1 ENGINE START REQUEST = OFFSELECTED DAU2 ENGINE START REQUEST = OFFDETAIL BADC1 BAROMETRIC ALTITUDE < 23000 FTADC2 BAROMETRIC ALTITUDE < 23000 FTSELECTED DAU2 STAB A/I VALVE POSITION = OPEN SELECTED DAU2 STAB A/I LOW PRESSURE = LOW PRESSUREDETAIL CSELECTED DAU2 STAB A/I VALVE POSITION = CLOSEDDETAIL D。
