For the power-on delay type time relay, when the coil is powered on, the power-on delay type contact acts after the delay time (the normally closed contact is opened and the normally open contact is closed), and the contact immediately returns to normal after the coil is powered off; For the power-off delay type time relay, when the coil is powered on, the power-off delay type contact acts immediately (the normally closed contact is opened and the normally open contact is closed). After the coil is powered off, the contact will not return to normal until the delay time is passed.The method of entering the recovery model is very simple.南宋淳二年(1242年)，四川安抚制置史兼重庆知府余始筑钓鱼城。1258年，蒙哥大汗挟西征欧亚非40余国的威势，分兵三路伐宋。蒙哥亲率的一路军马进犯四川，于次年2月兵临合川钓鱼城。蒙哥铁骑东征西讨，所向披靡，然而在钓鱼城主将王坚与副将张珏的顽强抗击下，却不能越雷池半步。7月，蒙哥被城上火炮击伤，后逝于温泉寺。钓鱼城保卫战长逾36年，写下了中外战争史上罕见的以弱胜强的战例，钓鱼城因此被欧洲人誉为“东方麦加城”、“上帝折鞭处”。2005年春，一个号称投资上亿，名为HRD的医药项目将落户蓝海。蓝海市两家龙头企业，南华制药和东森制药展开了激烈的竞争。南华的老板郭林打算在这次的竞争中一举击败东森的老板李小军，以了结双方多年来的宿怨。恰在此时，人称“贼公子”的熊伟为报父仇，潜入了郭林家，试图寻找置郭林于死地的证据，结果却意外碰上郭林的妻子方华和郭林的司机刘成仁偷情。熊伟从保险柜里拿走了一个U盘和部分现金。未曾想，他的这一举动成了引发蓝海市血雨腥风的导火线。不久刘成仁被人追杀，手指被砍掉，南华发生了爆炸，郭林心腹廖主任受伤。刑警队长刘建平意识到自己已经置身一场生死博弈之中。在随后的行动中，由于刘建平大意，导致了老搭档胡文成的牺牲，而嫌疑人柳东的身亡更令他感觉自己成了别人棋盘上的一粒棋子……
