8、 to start batteryAMSEG-S: Start control panel for E/G EG-S: 应急发电机的起动控制板 AMS: Engine monitoring alarm system AMS: 机舱监测报警系统2.2 冷车启动试验 (在试验前检查油、水）Starting test in cold state (oil and water to be check before test)2.2.1 蓄电池起动试验starting by charged batteries把启动控制板上的方式选择开关放在“MANUAL”位置，切断燃油供给，按下启动按钮，应急发电机自动

9、启动3次，然后给出启动故障报警信号。Set the MODE SELECT switch on start control panel to MANUAL position, cut off F.O.supply, push start button E/G will automatically try to start 3 times,then give start fail alarm.在蓄电池充足电后，在中途不充电的情况下，柴油机从冷态开始连续进行起动，起动次数不少于3次。Emergency diesel generator can be started smoothly (not le

10、ss than 3 times) by batteries without charging in cold condition.2.2.2柴油机自动起动试验 engine auto starting test包括主配电板失电时试验柴油机冷态自动起动的可能性及3次起动失败声光报警，并测量主配电板失电后至应急发电机开关自动合闸供电所需的时间(45秒内)，以及主发电机恢复运转后的自动分闸试验(60秒)，应急发电机自动停车。 when BUS BAR of MSB was black-out, check the possibility of E/G is starting automaticall
