4.8 当某些舱位作为压载使用后,请立即关闭相关舱位的取样进口阀,并按下控制柜面板上相应舱位的“人工切断”按钮,取消对该舱位的自动取样；此时,相应检测舱位工作指示灯显示为“人工切断”,自动循环检测将越过,不对该舱位进行取样检测.当该舱位压载水排空后,需要继续对该舱位进行检测时,请打开此舱位的取样进口阀,并再次按下控制柜面板上相应舱位的“人工切断”按钮,以恢复对该舱位的取样监测；此时,该舱位工作指示灯的“人工切断”指示熄灭.当系统循环取样切换至该舱位时,将自动先行吹扫该舱位取样管线,待排空取样管内水气、杂物后,进入正常取样模式,该舱位工作指示灯从“扫气”变为“取样”.
4.9 当需要对某些舱位进行持续监测时,可将工作模式开关选择为“手动取样”,通过“手动切换”按钮来人工切换至需要检测的舱位；此时,“手动取样”指示灯点亮,相应检测舱位工作指示灯显示为“取样”,显示屏持续显示当前测量点位的可燃气体浓度读数.如出现“管线故障”（手动时不具备自动吹扫功能）或者其他需要进行人工管线吹扫的情况时,可将工作模式开关选择为“手动扫气”,通过“手动切换”按钮来人工切换至需要进行扫气的舱位；此时,“手动扫气”指示灯点亮,相应检测舱位工作指示灯显示为“扫气”,完成后,再次将工作模式开关选择为“手动取样”,以完成取样监测功能.
4.10 系统通过双针压力表监测取样管线真空压力,如果某一舱位的真空压力过高,可以认为
该路取样管线堵塞或者该舱位压载水未完全排空,系统将执行自动吹扫,再次取样时,如果仍然检测到真空压力过高,“管线故障”指示灯闪烁,蜂鸣器鸣响,按下消音按钮后,蜂鸣器停止鸣响,“管线故障”指示灯变为常亮；如果某一舱位的真空压力过低,可以认为该路取样管线破损或真空泵故障,“管线故障”指示灯闪烁,蜂鸣器鸣响,按下消音按钮后,蜂鸣器停止鸣响,“管线故障”指示灯变为常亮；如果其他检测舱位再次管线堵塞情况,声光警报将再次出现；如果全部检测舱位管线正常,按下复位按钮后,“管线故障”指示灯熄灭.管线故障报警的舱位、时间信息的历史记录可在显示屏的相关页面查询、显示.出现“管线故障”指示时,系统将自动越过该舱位,进入下一舱位的检测,直到下一检测循环.
4.11 系统自动监测可燃气体传感器的工作状态,当出现传感器短路或者开路的情况,“传感器故障”指示灯闪烁,蜂鸣器鸣响,按下消音按钮后,蜂鸣器停止鸣响,“传感器故障”指示灯变为常亮；待故障排除后,按下复位按钮后,“传感器故障”指示灯熄灭.传感器故障报警的类别、时间信息的历史记录可在显示屏的相关页面查询、显示.
4.12 系统自动监测控制柜的电源供给状态,当主电源或者备用电源任一确失,“电源故障”指示灯闪烁,蜂鸣器鸣响,按下消音按钮后,蜂鸣器停止鸣响,“电源故障”指示灯变为常亮.当电源恢复供应后,“电源故障”指示灯自动熄灭.
4.13 系统参数可以在显示屏轻松修改,但为防止无关人员误操作,需要输入修改密码方能完成.
系统密码为“1111”.
4.14 标准气体的校验,可以通过按下“校验”按钮,将标准气接入柜内检测吸口端,验证系统的警报指示、传感器精度、真空取样泵切换动作等各项功能.

我来补答
4.8 when after certain seats on a ship take the ballast use, please immediately close is related the seat on a ship the sample import valve, and presses down on the control cubicle kneading board the corresponding seat on a ship “the artificial cut-off” the button, cancels to this seat on a ship mechanical sampling; This time, examines the seat on a ship work indicating lamp demonstration is correspondingly “the artificial cut-off”, the autocycle examination will cross, does not carry on the sample examination to this seat on a ship. After this seat on a ship ballast water evacuation, needs to continue when carries on the examination to this seat on a ship, please do open this seat on a ship the sample import valve, and presses down on once more control cubicle kneading board the corresponding seat on a ship “the artificial cut-off” the button, restores to this seat on a ship sample monitor; This time, this seat on a ship work indicating lamp “artificial cut-off” instruction extinguishment. When systemic circulation sample cut to this seat on a ship, will be automatic blows in advance sweeps this seat on a ship sample pipeline, after treating in the evacuation pipe ore sampler the moisture, the sundry goods, enters the normal sample pattern, this seat on a ship work indicating lamp from “sweeps was mad that” becomes “the sample”.
4.9 when needs to carry on to certain seats on a ship monitors continually, may the working pattern switch choice be “the manual sample”, adopts “the manual cut” the button to come the manual switching to the seat on a ship which needs to examine; This time, “the manual sample” the indicating lamp lightens, examines the seat on a ship work indicating lamp demonstration is correspondingly “the sample”, the display monitor demonstrates the current measuring point position continually the flammable gas density reading. If presents “the pipeline breakdown” (manual time when does not have blows automatically sweeps function) or other needs carries on the situation which the artificial pipeline blows sweeps, may be “manual sweeps the working pattern switch choice is mad”, adopts “the manual cut” the button to come the manual switching to need to carry on sweeps the gas the seat on a ship; This time, “manual sweeps was mad that” the indicating lamp lightens, examines the seat on a ship work indicating lamp demonstration is correspondingly “sweeps is mad”, after completing, the working pattern switch choice will be once more “the manual sample”, completes the sample monitor function.
4.10 systems through cross-pointing pressure gauge monitor sample pipeline vacuum pressure, if some seat on a ship's vacuum pressure is excessively high, may think that the this group sample pipeline jamming or this seat on a ship ballast water has not evacuated completely, the system will carry out blows automatically sweeps, when resampling, if still examined the vacuum pressure to be excessively high, “the pipeline breakdown” the indicating lamp twinkle, the buzzer resounds, after pressing down the deafen button, the buzzer stops resounding, “the pipeline breakdown” the indicating lamp becomes is often bright; If some seat on a ship's vacuum hypotonia, may think that this group sample pipeline breakage or the vacuum pump breakdown, “the pipeline breakdown” the indicating lamp twinkle, the buzzer resounds, after pressing down the deafen button, the buzzer stops resounding, “the pipeline breakdown” the indicating lamp becomes is often bright; If other examine the seat on a ship once more pipeline jamming situation, the acousto-optic warning will appear once more; If examines the seat on a ship pipeline to be normal completely, after pressing down the reset button, “pipeline breakdown” indicating lamp extinguishment. The pipeline malfunction alert's seat on a ship, the time information's historic record may in display monitor's related page inquiry, the demonstration. When appearance “pipeline breakdown” instruction, the system will cross this seat on a ship automatically, enters the next seat on a ship the examination, until next examination circulation.
4.11 system automatic monitor flammable gas sensor's active status, when presents the sensor to short-circuit or the opening situation, “the sensor breakdown” the indicating lamp twinkle, the buzzer resounds, after pressing down the deafen button, the buzzer stops resounding, “the sensor breakdown” the indicating lamp becomes is often bright; After treating the trouble shooting, after pressing down the reset button, “sensor breakdown” indicating lamp extinguishment. The sensor malfunction alert's category, the time information's historic record may in display monitor's related page inquiry, the demonstration. the 4.12 system monitors control cubicle's power supply condition automatically, when the main power source or the emergency power supply any one loses firmly, “the power failure” the indicating lamp twinkle, the buzzer resounds, after pressing down the deafen button, the buzzer stops resounding, “the power failure” the indicating lamp becomes is often bright. After the power source resumes the supply, “the power failure” the indicating lamp extinguishes automatically.
the 4.13 system parameters may with ease revise in the display monitor, but to prevent the irrelevant personnel misoperation, needs to input the revision password side to be able to complete. the system password is “1111”.
the 4.14 standard gas's verification, may through press down “the verification” the button, enters in the cabinet the standard gas welding to examine the suction port end, the confirmation system's warning indication, the sensor precision, the vacuum sample pump cut movement and so on each function.
