Thirdistomonitortheprogramoperation.一、防滑器的监视、故障存储和显示及诊断功能由上述监视功能所发现的各种故障，在防滑作用进行必要的切断或转换的同时，将故障以代码形式显示和存入主机的故障存储器。Whenthemonitorfunctionfindsvariousfaults,thefaultisdisplayedandstoredinthefaultmemoryofthehostcomputerintheformofcodewhiletheanti-skidfunctionisnecessarytocutofforconvert.在断电时该存储器所存故障信息能继续保存，直到故障排除后人工清除存储器内容为止。Whenpoweriscutoff,thefaultinformationstoredinthememorycancontinuetobesaveduntilthecontentsofthememoryaremanuallyclearedafterthefaultiseliminated.为了便于查看故障以利维修，主机面板上设有“显示”按钮和2位数字LED显示器。Inordertocheckthefaultsformaintenance,themainpanelisprovidedwithafault"display"buttonanda2-digitLEDdisplay.各故障预先按顺序编了代码，当按下“显示”按钮3s左右，可根据所显示的故障代码对各故障部件进行修理或更换。Eachfaultiscodedinsequenceinadvance.Whenthe"Display"buttonispressedforabout3s,eachfaultcomponentcanberepairedorreplacedaccordingtothedisplayedfaultcode.2．故障存储及显示功能FaultstorageanddisplayfunctionLED显示显示按钮一、防滑器的监视、故障存储和显示及诊断功能有关的故障在进行修理或更换而恢复正常后，应清除存储器中的故障信息，可先按动“显示”按钮，显示“89”后每显示一个故障代码，按动一次“清除”按钮，原故障代码变成“99”，表示该故障代码已被清除。Whentherelatedfaultsreturnstonormalafterrepairorreplacement,itisnecessarytoclearthefaultinformationinthememory.Atthistime,itshouldpressthe"Display"buttonfirstly,andpressthe"Clear"buttoneverytimeafaultcodeisdisplayedafter"89"isdisplayed.再显示一个故障代码时，再按一次“清除”按钮，以此类推，可把所有的故障信息全部清除。清除了全部故障显示后，显示器上显示“88”。Whentheoriginalfaultcodebecomesto"99",itmeansthefaultcodehasbeencleared.Whenanotherfaultcodeisdisplayed,pressthe"Clear"buttonagain,andsoonuntilallfaultinformationiscleared.Afterallfaultsarecleared,"88"isdisplayedonthedisplay.诊断按钮显示按钮清除按钮3．故障信息的清除Clearfaultinformation一、防滑器的监视、故障存储和显示及诊断功能当防滑器电源接通后系统进行诊断，主机立即对，对主机内部的CPU，在施行常用全制动之后进行诊断，可获得直观的试验效果。按下“诊断”按钮约3s，主机先对CPU、ROM、RAM逐项进行检查，然后对各轮对的速度传感器进行检查，最后对各轮对防滑阀进行检查和试验。“诊断”功能按钮用于对整个防滑系统进行逐项检查和试验，此功能只在静止状态下使用4．自诊断及诊断试验功能Self-diagnosisanddiagnostictestfunction各存储单元进行例行检查。Whenthepowersupplyoftheanti-skiddeviceisturnedon,thehostcomputerimmediatelydiagnosesthesystemandroutinelycheckstheCPUandstorageunitsinsidethehostcomputer.The"Diagnosis"functionbuttonisusedtocheckandtestthewholeaccelerationslipregulationitembyitem,andthisfunctionisonlyusedinthestateofrest.Theintuitivetestresultscanbeobtainedbydiagnosingafter
