It has been primarily designed to start and stop the generator depending upon the mains supply status. External autostart from a switch and user operated manual start is also provided. Additionally, the user has the facility to view all the system operating parameters via the LCD display.The DSE 5120 module monitors the engine, indicating the operational status and fault conditions automatically shutting down the engine and giving a true first up fault condition of an engine failure by a flashing COMMON ALARM LED. Exact failure mode information is indicated by the LCD display on the front panel.The powerful Microprocessor contained within the module allows for a range of demanding features to be incorporated as standard:• Graphical Icon based LCD display (excluding the need for translations and languages).• Engine parameter monitoring and instrumentation.• Generator Voltage, Frequency & Current instrumentation.• Mains failure monitoring and LED indication of status.• Fully configurable inputs for use as alarms or a range of different functions.• Extensive range of output functions using built in relay outputs.• ‘Front panel’ configuration of ALL (V4) operating parameters.• PC configurable using 5xxx configuration software for Windows™ and P810 interface module.The module is housed in a robust plastic case for front panel mounting. Connections to the module are via locking plug and sockets.2 CLARIFICATION OF NOTATION USED WITHIN THIS PUBLICATION.DSE Model 5120 Automatic Mains Failure & Instrumentation System Operators ManualPart No. 057-010 5120 OPERATING MANUAL ISSUE 1.2 28/02/2006 AH63 OPERATIONThe following description details the sequences followed by a module containing the standard ‘factoryconfiguration ’. Always refer to your configuration source for the exact sequences and timers observed by any particular module in the field.3.1 AUTOMATIC MODE OF OPERATIONaction.When the mains supply fails (or Remote Start signal (if configured) is applied) the following sequence is initiated:-The mains available LED extinguishes (if the sequence was started by mains failure) and the relevant mains over/under voltage LED will illuminate.The Remote Start Active indicator illuminates if the sequence is started by the remote start input.To allow for short term mains supply brownouts or false start signals the Start Delay timer is initiated. After this delay, if the pre-heat output option is selected then the pre-heat timer is initiated, and the corresponding auxiliary output (if configured) will energise.After the above delays the Fuel Solenoid is energised, then one second later, the Starter Motor is engaged.The engine is cranked for a pre-set time period. If the engine fails to fire during this cranking attempt then the starter motor is disengaged for the pre-set rest period. Should this sequence continue beyond the set number of attempts (fixed at 3), the start sequence will be terminated andFail to Startfault will be displayed accompanied by a flashing shutdown symbol.When the engine fires, the starter motor is disengaged and locked out at a pre-set frequency from the Alternator output. Alternatively a Magnetic Pickup mounted on the flywheel housing can be used for speed detection (This is selected using the front panel editor or PC).DSE Model 5120 Automatic Mains Failure & Instrumentation System Operators ManualPart No. 057-010 P5120 OPERATING MANUAL ISSUE 1.2 28/02/2006 AH7 After the starter motor has disengaged, the Safety On timer is activated, allowing Oil Pressure, High Engine Temperature, Under-speed, Charge Fail and any delayed Auxiliary fault inputs to stabilise without triggering the fault.Once the engine is running, the Warm Up timer, if selected is initiated, allowing the engine to stabilise before accepting the load.If the mains supply returns (or the remote start signal is removed if the start sequence was initiated by remote start), before the warm up timer has expired, the mains supply is kept on load and the return timer will begin.At the end of the warming timer, If the mains supply is still failed, or the remote start signal is still active, the load is transferred to the generator - First the mains load switching device is opened, then ¾ second later, the close generator output is activated.On return of the mains supply the mains in limit LED will illuminate, and the under/overvolts LEDs will extinguish. Additionally (or upon removal of the Remote Start signal if the start was initiated by remote start), the return delay timer is initiated after which the load Transfer signal is de-energised, removing the load. ¾ second later, the mains load switch is closed, returning the mains on load.If the generator set has been on load, The Cooling timer is then initiated, allowing the engine a cooling down period off load before shutting down.Once the Cooling timer expires the Fuel Solenoid is de-energised, bringing the generator to a stop.Should the mains supply fail, or Remote Start signal be re-activated during the cooling down period, the set will return on load.DSE Model 5120 Automatic Mains Failure & Instrumentation System Operators ManualPart No. 057-010 5120 OPERATING MANUAL ISSUE 1.2 28/02/2006 AH83.2 MANUAL OPERATIONTo initiate a start sequence in MANUAL(indicated by an LED indicator beside the button), pressing the START (I) button will initiate the start sequence.If the pre-heat output option is selected this timer is then initiated, and the auxiliary output selected is energised.After the above delay the Fuel Solenoid is energised, then the Starter Motor is engaged.The engine is cranked for a pre-set time period. If the engine fails to fire during this cranking attempt then the starter motor is disengaged for the pre-set rest period. Should this sequence continue beyond the set number of attempts (fixed at 3), the start sequence will be terminated andFail to Start fault will be displayed accompanied by a flashing shutdown indicator.When the engine fires, the starter motor is disengaged and locked out at a pre-set frequency from the Alternator output. Alternatively a Magnetic Pickup mounted on the flywheel housing can be used for speed detection (This is selected using the front panel editor or PC).After the starter motor has disengaged, the Safety On timer is activated, allowing Oil Pressure, High Engine Temperature, Under-speed, Charge Fail and any delayed Auxiliary fault inputs to stabilise without triggering the fault.Once the engine is running, the Warm Up timer, if selected is initiated, allowing the engine to stabilise before it can be loaded.The generator will run off load, unless the mains supply fails, or a Remote Start signal is applied.The generator will continue to run On load regardless of the state of the mains supply and/or remote start input until the Auto mode is selected, the Stop button is pressed, or an electrical trip or shutdown alarm is detected.Selecting STOP (O) de-energises the FUEL SOLENOID , bringing the generator to a stop.DSE Model 5120 Automatic Mains Failure & Instrumentation System Operators ManualPart No. 057-010 P5120 OPERATING MANUAL ISSUE 1.2 28/02/2006 AH93.3 TEST OPERATIONTo enter TESTmode, press the pushbutton, this will be confirmed by the LED indicator beside the button. Pressing the START (I) button will initiate the start sequence.If the pre-heat output option is selected this timer is then initiated, and the auxiliary output selected is energised.After the above delay the Fuel Solenoid is energised, then the Starter Motor is engaged.The engine is cranked for a pre-set time period. If the engine fails to fire during this cranking attempt then the starter motor is disengaged for the pre-set rest period. Should this sequence continue beyond the set number of attempts (fixed at 3), the start sequence will be terminated andFail to Startfault will be displayed accompanied by a flashing shutdown indicator.When the engine fires, the starter motor is disengaged and locked out at a pre-set frequency from the Alternator output. Alternatively a Magnetic Pickup mounted on the flywheel housing can be used for speed detection (This is selected using the front panel editor).After the starter motor has disengaged, the Safety On timer is activated, allowing Oil Pressure, High Engine Temperature, Under-speed, Charge Fail and any delayed Auxiliary fault inputs to stabilise without triggering the fault.Once the engine is running, the Warm Up timer, if selected is initiated, allowing the engine to stabilise before it can be loaded.The load will be transferred automatically to the generator.The generator will continue to run On load regardless of the state of the mains supply and/or remote start input until the Auto mode is selected, the Stop button is pressed, or an electrical trip or shutdown alarm is detected.Selecting STOP (O) de-energises the FUEL SOLENOID , bringing the generator to a stop.DSE Model 5120 Automatic Mains Failure & Instrumentation System Operators ManualPart No. 057-010 5120 OPERATING MANUAL ISSUE 1.2 28/02/2006 AH 104 PROTECTIONSThe module will indicate that an alarm has occurred in several ways;If no alarms are present the LCDwill extinguish any alarm icons.In the event of a warning alarm the LCD will display the appropriate icon. If a shutdown then occurs the module will display the appropriate icon. The original warning alarm icon will remain displayed.Charge alternator warning (all symbols steady)Followed by….Charge alternator warning indicator stillpresent, common alarm indicator haschanged to a shutdown symbol and isnow flashing.Also present is the flashing overspeedLED.Overspeed and Shutdown alarm Icons are displayed flashing. The original warning will remain displayed as long as the triggering conditions remain. Any subsequent warnings or shutdowns that occur will be displayed steady, therefore only the first-up shutdown will appear flashing.4.1 WARNINGSWarnings are non-critical alarm conditions and do not affect the operation of the generator system, they serve to draw the operators attention to an undesirable condition.BATTERY CHARGE FAILURE, if the module does not detect a voltage from the warning light terminal on the auxiliary charge alternator the icon will illuminate.FAIL TO STOP, If the module detects the engine is still running when the ‘Fail to stop timer’ expires, then the module will display:-AUXILIARY INPUTS, if an auxiliary input has been configured as a warning the appropriate LCD segment will be displayed:-Part No. 057-010 5120 OPERATING MANUAL ISSUE 1.2 28/02/2006 AH 124.2 SHUTDOWNSShutdowns are latching and stop the Generator. The alarm must be cleared, and the fault removed to reset the module.The appropriate icon will also be displayed flashingFAIL TO START , if the engine does not fire after the pre-set number of attempts has been made a shutdown will be initiated.Theicon will illuminate.EMERGENCY STOP , removal of the Positive DC Supply from the Emergency Stop input initiates the following sequence, firstly it will initiate a controlled shutdown of the Generator and prevent any attempt to restart theGenerator until the Emergency Stop push-button has been reset. Secondly it removes the Positive DC supply from both the Fuel Solenoid and Starter Solenoid. The icon will illuminate.NOTE:- The Emergency Stop Positive signal must be present otherwise the unit will shutdown. LOW OIL PRESSURE , if the module detects that the engine oil pressure has fallen below the low oil pressure trip setting level after the Safety On timer has expired, a shutdown will occur.Theicon will illuminate.HIGH ENGINE TEMPERATURE if the module detects that the engine coolant temperature has exceeded the high engine temperature trip setting level after the Safety On timer has expired, a shutdown will occur.Theicon will illuminate.OVERSPEED / OVERFREQUENCY , if the engine speed exceeds the pre-set trip a shutdown is initiated. Theicon will illuminate. UNDERSPEED / UNDERFREQUENCY , if the engine speed falls below the pre-set trip after the Safety On timerOIL PRESSURE SENDER OPEN CIRCUIT, if the module detects a loss of signal from the oil pressure sender (open circuit) a shutdown is initiated. The LCD will indicate:-(Steady) (And ‘-----‘ on the engine oil pressure instrument). Sender failure is not delayed, it is an immediate shutdown.AUXILIARY INPUTS, if an auxiliary input has been configured as a shutdown the appropriate LCD segment will be displayed:-LOSS OF SPEED SIGNAL, if the speed sensing signal is lost during cranking, a shutdown is initiated.The icon will illuminate (Steady). As engine speed cannot be determined, the entire “fail to stop” timer is observed before the alarm can be reset and the engine restarted.Part No. 057-010 5120 OPERATING MANUAL ISSUE 1.2 28/02/2006 AH 14 5 DESCRIPTION OF CONTROLSThe following section details the function and meaning of the various controls on the module.Instrumentation page buttonLCD DisplayCommon alarm LED User configurable indicatorsOperation andMains / generator statusLED indicatorsphase AC voltages ALARM ICONSUSER DEFINEDINDICATIONSPart No. 057-010 5120 OPERATING MANUAL ISSUE 1.2 28/02/2006 AH 16 5.2 LCD DISPLAY AREASInstrument ValuesUnits of MeasureDisplay Information &Alarm IconsUser Definable Alarms/Indicators5.3 VIEWING THE INSTRUMENTSIt is possible to manually scroll to display the different instruments by repeatedly operating the scroll button.

康明斯发电机技术AGN 030 – 服务和维护说明书

Application Guidance Notes: Technical Information from Cummins Generator Technologies AGN 030 – Service and MaintenanceDESCRIPTIONSuitable service and maintenance are vital to the reliable operation of the alternator and the safety of anyone coming into contact with the alternator. The alternator should be inspected between scheduled maintenance, in line with inspection procedures and schedules provided by the manufacturer to identify any potential failure modes, signs of misuse or excessive wear and tear.An alternator specific Owner’s Manual (also known as Installation, Service and Maintenance Manual) is supplied with every alternator. The manuals are also published on the website. Each manual includes a Section on Service and Maintenance.The service activities are intended to maximise the life of the alternator but shall not vary, extend or change the terms of the manufacturer’s standard warranty or the customer’s obligation in that warranty.Each service interval is a guide only, developed on the basis that the alternator was installed and is operated in accordance with the manufacturer’s guidelines. If the alternator is located and/or operated in adverse or unusual environmental conditions, the service intervals may need to be more frequent. The alternator should be continually monitored between services to identify any potential failure modes, signs of misuse or excessive wear and tear. Recommended Service ScheduleThe recommended service schedule published in the manual shows the recommended service activities in table rows, grouped by alternator subsystem. Columns of the table show the typesof service activity, whether the alternator must be running, and the service levels. Service frequency is given in running hours or interval time, whichever is sooner. A cross (X) in the cells where a row intersects the column shows a service activity type and when it is required. An asterisk (*) shows a service activity done only when necessary.Service level documents referred to in the recommended service schedules can be purchased directly from Cummins Generator Technologies Customer Service Department, by telephone on +44 1780 484732 or by email: **************************************************. STAMFORD AlternatorsThe recommended service schedule for STAMFORD alternators can be found in Section 7 of the manual, with the following breakdown of sub-sections:Recommended Service ScheduleBearingsControlsCooling SystemCouplingRectifier SystemTemperature SensorsWindings.AvK AlternatorsThe recommended service schedule for AvK alternators can be found in Section 10 of the manual, with the following breakdown of sub-sections:Preventive ServicingSafety PrecautionsRecommended Service ScheduleServicing – General StructureVibrationServicing the Bearings and the Lubrication SystemGenerators with Bearing InsulationService WindingsServicing the Generators CoolerRepairs, Dismantling and Reassembly.Importance of Alternator MaintenanceThe maintenance programme is developed to meet the needs of different alternator designs. There are three types of maintenance strategies;∙Reactive maintenanceo Failure or abnormal operation.∙Preventive time based maintenanceo Time based maintenance.o Based on manufacturer’s experience.Predictive / condition based maintenanceo Maintenance based on actual measurements.A regular preventive maintenance schedule will ensure peak performance, maximize alternator life, maximized reliability and minimize breakdowns.INSTALLATION CONSIDERATIONSThe alternator must be installed in an accessible location with easy access to the main terminal box, bearing cap, air filter, louvers (inlet and outlet) and NDE/DE end brackets. The mentioned access points provide easy access to internal alternator components as shown in Figure 1. This will allow the execution of periodic inspections, local maintenance and removal of the alternator for external services.Figure 1: Internal alternator components that require periodic maintenance. Alternators LiftingDifferent alternator designs must be lifted by hooks or shackles attached to the lifting points (lugs or eyes). Chains of sufficient length, and a spreader bar if necessary must be used when lifting the alternators so as not to damage the terminal box, alternator parts and prevent the rotor from failing out on 1 bearing alternators as shown in Figure 2. When lifting entire Generating Set, the installation engineer must use specially designed Generating Set lifting points, and not alternator lifting lugs.Figure 2: Showing an example of the right and wrong alternator lifting methods. Mechanical CouplingInstallation engineers should follow the alternator manufacturer’s integration instructions provided in the Owner’s Manual. When coupling, the engineer should not attempt to rotate the alternator rotor by levering against the vanes of the cooling fan as shown in Figure 3 as the fan is not designed to withstand such forces and will be damaged. The holes of the coupling discs should be aligned with the flywheel holes by cranking the engine. Additional forces should not be put on the bearings while assembling the coupling half as it will damage the bearings.Figure 3: Alternator cooling fan vanes.SafetyIt is important to follow the alternator manufacturer’s general and local health and safety instructions. Incorrect installation, service or replacement of parts can result in severe equipment damage and personal injury. Only qualified individuals should perform electrical and mechanical component installations. Safety information signs are provided on the equipment to indicate hazards and emphasize instructions.Figure 4: Examples of the safety signs provided on an alternator. Environmental ConditionsAlternators installed in Generating Sets that are sited in arduous ambient environmental conditions may be susceptible to breakdown at their location site, if appropriate service and maintenance is not carried out. Ensuring reliable satisfactory service though, starts with careful consideration being given to the design of the ventilation systems that will be shared by both alternator and engine. Simplifying the considerations to just deciding to have a relatively simple canopy with large openings for the benefit of the engine and then considering the alternator satisfied by the fitting of low cost air filters will result in operating problems.Decisions at the Generating Set design stage about the Canopy design and airflow control must include discussions with the alternator manufacturer to ensure that the appropriate optional extra air-filter / louver kit is nominated or the IP rating of the alternator is increased and that a bespoke maintenance regime is implemented for the complete Generating Set.Refer to AGN072 – Environmental Conditions, for guidance on appropriate installation from the alternator manufacturer’s viewpoint.Alternators in Coastal LocationsFor example; an RTG Crane application is a quite unique situation. For reasons of making the alternator output characteristics suitable to power the Crane’s drive motor, combined with the duty cycle of the variable crane motor load, the alternator is usually operating with quite low winding temperatures. Whilst this low temperature situation would normally be considered to be beneficial, it does introduce a problem when the operating environment is a salt laden with a high humidity. The accepted winding temperature at which moisture is driven from the windings is some 95o C and experience is showing that RTG applications do not achieve this. So we have a winding contaminated by a salt laden atmosphere, combined with the dust and pollutants around a working dockside, plus RIC engined port vehicles adding exhaust by-products to this winding contamination problem. Add to this the humidity and moisture associated with local weather conditions, forming surface moisture on the alternator’s outhang, a winding that is not getting hot enough to drive the moisture off and we have created a winding insulation system with much reduced ‘barrier’ capabilities.The above considers the contaminants that weaken the winding insulation system. The following explains the additional electrical stresses associated with the Variable Speed Drive units used to power the various crane movements.These VSD’s are Non Linear Loads [NLL], with quite high levels of harmonic distortion. The resulting harmonic voltage distortion results in transient voltage conditions that may well be twice the peak value that the alternator would experience under normal linear load conditions.These high transient voltage spikes stress the electrical insulation system, with which a clean uncontaminated winding insulation system can cope. But a contaminated winding will find such transient voltage spikes difficult to contain, followed inevitable by the breakdown of the insulation barrier and winding short circuit.The decision to have the new alternator fitted with IP44 inlet louvers will ensure that whilst the alternator is running, the inlet cooling air is being filtered and moisture droplets are being removed by the Premaberg filter system.However the IP44 filter assembly is not really addressing all the problems of the location being in a coastal, salt laden atmosphere. The problem with salt is that it will form a moisture absorbing film of contamination on the alternator’s winding. When the alternator is working and the windings are hot, the moisture is driven off the windings surface and the insulation resistance - IR - will be high enough to ensure that no insulation breakdown or surface tracking occurs. However; as soon as the Generating Set is stopped, the alternator’s local environment becomes extremely humid, it is at this point the hygroscopic layer of salt that has formed on the windings will absorb moisture and this will result in the windings IR value being reduced to a low level and so, an inability to insulate/isolate phase to phase and phase to earth. Therefore, when the Generating Set is next started and the alternator excites to the normal working voltage - electrical pressure - there is a real risk that an insulation failure will occur as a result of insulation breakdown initiated by surface tracking.The ideal solution is to filter the salt from Generating Set cooling air. But the practicalities must include control of the humidity level of the alternator’s environment and this involves far more than the fitting of an alternator anti-condensation heater.The most successful schemes involve a fan heater bl owing several kW’s of hot air around the Generating Set ‘chamber’ to keep the humidity RH% as low as possible. Obviously, this needs an electrical power supply when the Generating Set is not running and so may well not be an easy option.There may be a way of running-on the Generating Set after its programmed service duty. This would be in a way devised to keep hot dry air circulating whilst the whole Generating Set area temperature is gradually reduced to stop the sudden increase in RH% that occurs around Generating S ets when they are stopped and left trapped in their ‘sweat box’ canopies.It could be that Generating Set’s are operating in parallel, or a Generating Set is operating in parallel with a mains supply. This then suggests an option to introduce some Generating Set environment control, because it would seem that there is always an electrical supply available. We cannot rule out that the stresses associated with miss-paralleling, or the instability of the local mains supply e.g.; micro-interruptions, will damage insulation systems and promote failures. But if the site history is one of winding failures occurring at the point/moment of starting the Generating Set ready to put the unit back into service then, from experience, we would consider saline contamination is the prime culprit.MAINTENANCE OF THE WINDING INSULATION SYSTEMThe only way to check on the condition of the winding insulation system, is by introducing a regular procedure to check the stator winding Insulation Resistance (IR) value and although not normal practice for a low voltage scheme, the Polarisation Index [PI] should be measured too, if the alternator is installed in any challenging environment. This check of IR and PI need only be carried out to the stator winding. The spinning of the rotor and the fact that it operates at low voltages means that it is not, as much, at risk.Refer to AGN015 – Testing Winding Insulation Systems for details of IR and PI testing.At the first sign that the IR and PI are low, the alternator stator winding must be cleaned.T he exciter field is another ‘at risk’ component and the fact that it operates with dc. means that it has a high risk factor due to its operation with fixed polarisation. If the exciter field insulation fails it will also take out the AVR.Cleaning windingsIf cleaning of the windings becomes necessary, then the preferred method is to completely strip the alternator to enable a thorough inspection and then a washing process, which will result in dirt removal by encouraging a washing-out of dirt by an action that will not result in the dirt being forced further into the winding assembly. The washing medium should be clean hot water applied from a directional nozzle at a pressure not exceeding 3bar.At no point should the winding insulation be subjected to a jet of water pressure that is deforming the insulation materials.For extremely oily contaminants, an alternative method is to use a hot pressure wash - not exceeding 3bar – with an added solvent based biodegradable cleaner of neutral pH. Note: ‘Autosmart’ and Aquawash’ are trade names of such biodegradable cleaners.Water-based Alkaline Detergents should not be used for cleaning as they contain ‘wetting agents’ that leave contaminants - in the form of salts - on the winding surfaces. These contaminants are hygroscopic and therefore readily absorb moisture, which will lower the insulation resistance and promote surface tracking.Caution: Inappropriate or badly executed cleaning methods will leave contamination embedded in the winding crevices and this local contamination will promote degradation of the insulation system.After the cleaning process, the windings must be slowly[over several hours] heated to at least 100degC in a thorough drying out procedure of perhaps twelve to twenty four hours. The insulation resistance [IR], phase to phase, and phase to earth, must be measured during this process.Refer to the alternator’s Owner’s Manual (Installation, Service & Maintenance Manual) for the drying out procedures and the IR test procedure, including the values, in Mega-Ohms, that thewinding must achieve before the winding IR can be said to be high enough for the wound assembly to be considered a serviceable unit.Once the windings have been cleaned and the insulation resistance improved to what is considered to be a satisfactory level, the clean and dry windings should be treated with an appropriate ‘over-coating’ electrical anti-tracking resin / varnish. This treatment will offer protection from further immediate in-service recontamination of the winding surface. The chosen anti-tracking material should be of the same insulation thermal rating as the alternator’s insulation system - Class ‘F’ or Class ‘H’.Checks must also be made to ensure that the electrical anti-tracking resin / varnish will adhere to the windings original impregnation materials.Application Guidance Notes are for information purposes only.

目录序-------------------------------------2 功能介绍----------------------------3 安装说明----------------------------8 故障处理---------------------------11序电子调速系统是发动机速度调节系统,其主要任务是:保持发动机转速在设定转速运转。

机械调速和电子调速的不同之处在于:电子调速能够通过控制单元(1·Fig.1.)来“感受”实际转速与设定转速的不同,将此差值变换传给执行单元(执行器)来调节燃油流量从而增加或降低发动机转速转速,使之保持在设定转速运行。

调速板有以下调节功能,只须将黑色圆胶盖打开即可进行调节:1、调节怠速转速“IDLE”,把端子“G”和“M”短接,调节电位器(4·Fig.3.),调节频率范围在1200-4100HZ之间,顺时针调节电位器将增加怠速转速。

2、运行速度调节“SPEED”,频率调节范围在100-6000HZ,顺时针调节将增加发动机转速。

上面的调节频率来自电磁传感器(转速传感器),频率值取决于发动机飞轮齿数和发动机转速。

即:频率值=发动机转速(r/s)×发动机飞轮齿数例:CUMMINS NTA855-G1发动机齿数是118,转速在1500r/min(25r/s):25×118=2950HZ.Fig.3.调速板ESD55001、运行速度调节、设定 5、下垂调节2、增益调节、设定 6、启动燃油调节3、稳定性控制 7、转速坡度调节4、怠速调节注:不同型号调速板各电位器排列位置略有不同,请以标识为准3、增益调节“GAIN”,转速的灵敏度是通过调节“GAIN”电位器(2·Fig.3.)实现的,顺时针调节将使灵敏度增加;——顺时针调节“GAIN”电位器,直到发动机出现抖动,再旋回1/8圈;——当调整灵敏度时频率可能会有很小的变化,这个变化可通过调整“SPEED”电位器来调整。

当CPU板J5第7脚的运行开关RUN闭合时,J1的1脚输出24V电压,PT泵电磁阀开关SWITCHED得电开启,EFC调速控制器4得电工作,使控制器2的轴转到最大供油位置。

同时,CPU板J1的第3脚输出起动信号到启动马达,使发动机启动。

发动机启动后,交流发电机的中点(N)电压(约12V)作为发动机已启动的信号,通过J2的第3脚输入CPU控制板,从而切断J1第3脚输出的信号,使启动机停止工作。

若一次启动不成功,停10s后将自动再次启动,若连续三次启动不成功,则停止启动,故障灯点亮。

发动机正常工作后,发动机的各种参数通过J3插座输入CPU板,由J4输出各种报警灯信号。

按J5的复位/灯检查按钮,可使CPU复位,同时进行各种报警灯测试,若所有报警灯都亮,说明整个报警控制系统工作正常。

发动机启动以后,EFC调速器4把来自电磁传感器的电讯号与现有的参考点(W2)相比较,输出差压电流信号,使执行器2的轴转动,控制进入喷嘴的燃油流量,从而改变发动机的转速和功率。

当发动机在W2调定的某一转速下稳定工作时,调速过程如下:负载↑↓→(转速传感器3)发动机转速↓↑→EFC调速器4输出电流↑↓→执行器2供油量↑↓→发动机转速↓↑→使发动机转速稳定在某一定值工作。

目录序-------------------------------------2 功能介绍----------------------------3 安装说明----------------------------8 故障处理---------------------------11序电子调速系统是发动机速度调节系统,其主要任务是:保持发动机转速在设定转速运转。

机械调速和电子调速的不同之处在于:电子调速能够通过控制单元(1·Fig.1.)来“感受”实际转速与设定转速的不同,将此差值变换传给执行单元(执行器)来调节燃油流量从而增加或降低发动机转速转速,使之保持在设定转速运行。

Fig.1. 电子调速系统结构1、控制单元(调速板)4、停车阀/燃油阀2、发动机速度传感器5、电池3、执行器功能介绍发动机转速传感器发动机转速传感器安装于发动机飞轮壳上方正对飞轮,当飞轮齿经过转速传感器,传感器就产生一交流电信号(每一齿产生一个脉冲信号)。

脉冲电压在1V AC~30V AC之间转速传感器的安装螺纹是5/8”-18 UNF-2A Fig.2. 传感器部分1、转速传感器2、飞轮齿控制器(调速板)电子控制器(调速板)的基本功能是:比较输入转速信号与设定值,然后将校正或不变的指令传输给执行器。

调速板有以下调节功能,只须将黑色圆胶盖打开即可进行调节:1、调节怠速转速“IDLE”,把端子“G”和“M”短接,调节电位器(4·Fig.3.),调节频率范围在1200-4100HZ之间,顺时针调节电位器将增加怠速转速。

2、运行速度调节“SPEED”,频率调节范围在100-6000HZ,顺时针调节将增加发动机转速。

上面的调节频率来自电磁传感器(转速传感器),频率值取决于发动机飞轮齿数和发动机转速。

即:频率值=发动机转速(r/s)×发动机飞轮齿数例:CUMMINS NTA855-G1发动机齿数是118,转速在1500r/min(25r/s):25×118=2950HZ.Fig.3.调速板ESD55001、运行速度调节、设定 5、下垂调节2、增益调节、设定 6、启动燃油调节3、稳定性控制 7、转速坡度调节4、怠速调节注:不同型号调速板各电位器排列位置略有不同,请以标识为准3、增益调节“GAIN”,转速的灵敏度是通过调节“GAIN”电位器(2·Fig.3.)实现的,顺时针调节将使灵敏度增加;——顺时针调节“GAIN”电位器,直到发动机出现抖动,再旋回1/8圈;——当调整灵敏度时频率可能会有很小的变化,这个变化可通过调整“SPEED”电位器来调整。

4、稳定性控制“STABILITY”,速度调节时间常数是通过调节“STABILITY”电位器实现的。

时间常数即负载发生变化后恢复到发动机额定转速所需要的时间。

——顺时针调节“STABILITY”会缩短负载变化后系统的恢复时间;逆时针调节则使恢复时间加长。

5、转速降操作“DROOP”,顺时针旋转“DROOP”(转速降)调节器,转速降值将增加,当处于降落状态时,发动机速度将随负载的增加而降低;短接“G”和“H”可提高转速。

6、启动燃油调节“STARTING FUEL”,顺时针调节“STARTING FUEL”电位器,发动机启动过程中的燃油流量将增大,顺时针调节至最大,启动过程中的燃油将不受限制,执行器动作至最大;逆时针调至最小,启动过程中燃油将非常小或为零。

7、速度缓冲调节“SPEED RAMPING”,顺时针调节“SPEED RAMPING”电位器,发动机转速加速度减慢,加速时间最长可调到20秒。

ESD5500系列调速板ESD5500系列调速板包含ESD5100系列调速板的所有特性,另外,ESD5500系列还具有发动机燃油供给控制,从而消除过量燃油,降低了排烟浓度,提高了环保效益。

ESD5500系列与ESD5100系列的一点区别是:怠速选择开关的连接端子,ESD5500系列是“M”和“G”,ESD5100系列是“M”和“L”。

Fig.4. ESD5500调速板调速板的调整按如下方法对调速板进行预设:--STARTING FUEL 顺时针调最大(最大燃油)--SPEED RAMPING 逆时针调最小(最快启动)1、启动发动机并调节“SPEED”、“GAIN”、“STABILITY”,此时燃油供给将不受限制。

2、连接端子“M”和“G”,将发动机置于怠速运行状态。

3、调节怠速转速至略高于低转速报警设定值,保证低转速不动作。

4、逆时针调节“STARTING FUEL”直至发动机转速开始下降,然后顺时针微调“STARTING FUEL”使怠速转速恢复至要求值。

5、停机ESD5500系列调速板可选择以下两种运行方式之一:方式一:启动机组并直接加速至运行速度(发电机组等)断开端子“M”与“G“间的连接。

启动发动机并调节从怠速到额定速度的“SPEED RAMPING”(速度斜率),以获得最少排烟量。

若启动排烟过量,则需逆时针微调“STARTING FUEL”(启动燃油)。

若起动时间过长,则需顺时针微调“STARTING FUEL”(启动燃料)。

方式二:启动发动机并在怠速状态下运行一段时间后加速至运行速度此种方式将启动过程从加速过程中分裂出来,以更好地优化排放,使排放达到最低。

用一个开关替代端子“M”和“G”间的连接,通常用一个油压开关。

启动发动机,若启动排烟过量,则需逆时针微调“STARTING FUEL”(启动燃油)。

若起动时间过长,则需顺时针微调“STARTING FUEL”(启动燃油)。

当开关断开,当发动机从怠速加速到额定速度时,调节“SPEED RAMPING”(速度斜率)以获得最少量的排烟。

执行器执行器是一个电磁装置,对装有RQ调速超速保护装置的高压喷油泵,可安装美国GAC公司的ACB225或ACB250型外置式执行器。

Fig.5.带机械超速保护的发动机Fig.6.ACB225执行器1、RQ调节装置1、接线端子(连接到调速板)2、分离式外置执行器2、盖板对于康明斯PT燃油泵,安装的是康明斯EFC执行器1Fig.7. EFC 执行器1、接线端子安装说明电源本调速系统采用DC 12V或DC 24V电源,调速系统要与控制系统绝缘,采用不接地线路。

24V时最大工作电流为4A,12V时为8A;所以调速系统电源要装15A快熔(12V)或8A快熔(24V)。

注:电池充电器不能作为电源连接到调速单元,以免造成系统过电压。

调速板工作环境调速板应安装于无震源和热源的地方,环境温度应在40℃--85℃范围内,否则将产生温漂。

配线配线如下图:Fig.8. 调速系统接线图1、调速板2、执行器3、传感器4、电位器5、燃油阀/停车阀6、电源开关7、熔断器(保险) 8、控制器9、蓄电池:12V或24V电磁兼容性易受到的电磁干扰——通过电缆或直接辐射到控制电路所产生的大干扰信号可对控制系统产生相反的影响。

所有的GAC速度控制单元都包括了过滤和屏蔽设计,以保护灵敏电路不受到外部中等强度的干扰源干扰。

由于预知干扰的强度是困难的,所以要求将包括磁发电机、固体点火系统、无线电发射机、调压器、充电器看作干扰源。

外部可疑的范围,即那些受到辐射或导体连接,或将影响控制系统的操作。

对所有的外部连接要求使用屏蔽电线。

务必使所有屏蔽线包括速度传感器屏蔽线共一个终端,将该端连接到速度控制单元盒子的一个信号点上。

将速度控制单元安装到一个接地的金属后板上。

或将其放到一个密封的金属盒子中。

当干扰信号直接辐射时,放射线将通过控制系统所在的空间。

为将控制系统电气与这类干扰隔离,使用金属屏蔽或金属容器通常是有效的。

当干扰信号由电线交叉连接所产生的,通常会传导给控制系统电子。

屏蔽线或安装的过滤器通常是不起作用的。

作为一项有助于减少自然干扰的方法,KT130中GAC支持电池线过滤器或电缆屏蔽。

为减少自然辐射的电磁干扰,可用一个屏蔽器P/N CA114罩住GAC和它的分配装置。

在严格的高能量干扰场所,如当控制系统直接暴露在电力传送源极中,将要求一个特别的电磁干扰等级屏蔽。

对于这种情况,请与GAC供应工程师联系以获得特别的建议。

速度传感器(电磁传感器)强的电磁速度传感信号将排除丢失或增加脉冲的可能。

速度控制单元将用0.5V RMS速度传感信号进行较好的控制。

在控制速度中,要求速度传感信号为3V RMS或更高。

信号的测量由端子C和D来执行。

通过减少速度传感器顶端与发动机齿圈齿顶间隙,可增加速度传感器信号范围。

在发动机停机时,将传感器旋到与齿轮相接触,再向回旋3/4转可得到一个较满意的空气间隙。

Fig.9. 发动机转速传感器安装位置A.距离值在0.7—1.0mm(0.028-0.039英寸)故障处理1、发动机启不动电池电压检查调速板上“E”“F“之间的电压最低电压值如下:—— 8V DC(12V系统)——17V DC(24V系统)检查调速板电源的快速熔断器是否完好A、执行器断开调速板电源并断开执行器连线,用万用表测量执行器线圈阻值,执行器阻值应符合以下值:GAC ACB275执行器:——A-B:3±1ohms——C-D:3±1ohmsCUMMINS EFC执行器:——A-B:6.8—7.6ohms将调速板“A”端子至执行器连线拆下,串联一电流表后接“E”,然后接通电源,此时执行器应动作至最大燃油位,且电流表读数应在4A 左右(12V系统)或2.5A左右(24V系统)。

C、传感器启动机组同时用电压表测量调速板“C”、“D”间的电压,电压值应不小于1.0V AC。

如果无电压:拆开调速板‘C“、”D“连线,再次启动机组并测量传感器两线间的电压,如果有电压,则调速板坏。

如果传感器仍无电压:测量调速板“C”和”D“间的阻值,阻值应在50—250欧姆之间,如正确,检查传感器与飞轮齿之间的距离0.7—1.0mm(0.028—0.039英寸)之间。

注:距离越小信号越强D、调速板⑴检查设定⑵检查“G‘和“P”之间电压,正确的电压应为10V DC,无论是12V还是24V系统。

错误的值说明“SPEED”电位器坏。

⑶检查“A“与”F“之间的电压:断开燃油并启动机组,测量其电压,应在1.5—2.5V DC之间。

错误的值可能为:——“SPEED“电位器设置太低——到执行器的线路故障——“SPPED“电位器坏测量时注意极性2、发动机超速⑴接通调速板电源,执行器摆动至最大燃油位⑵测量调速板“A”“F”间电压注:不要启动机组如果电压在1.5—2.5V DC,则:——“SPEED”设定太高——调速板坏如果电压大于2.5V DC,则:——执行器或机械连接摩擦太大如果电压小于1.5V DC,则:——调速板坏⑶拆开调速板“C”“D”连线——如果执行器仍保持在最大燃油位,调速板坏——如果执行器回到最小燃油位,则发动机转速信号出问题,检查传感器与调速板之间连线,并要求屏蔽。
