一)、功能检测
1、将控制板接入检测台,接通电源 将控制板正确连接在检测台上,检测台电源接市电(220V AC/50Hz)。
2、上电,显示屏显示温度42℃;水流量电压5±0.5V;比例阀无电流。
3、①打开水流量,闭合风压,点火,闭合反馈。比例阀,主阀打开,分段阀打开。燃烧正常。按下45℃(85℃)开关键显示4585)±1
断开风压开关,显示故障:E5  ③按短路按键或拔出水探头插,显示故障:E0  拔主阀显示故障:E8
⑤断开防干烧开关,显示故障:E3 
4、进入菜单:按住下降键,上电,显示PP,按下开关键,3S内按下下降键,显示PL。闭合水流量,风机高速运转,闭合风压开关,开始点火,风机低速运转,延时1S 吸比例阀(吸阀电压≥24V),滞后0.5S再吸主阀(吸阀电压≥24V,吸阀时间0.4±0.1S,维持电压≥12V)。
5、点火时间内闭合反馈开关(火焰灵敏度≥5.1M)约1S 土木工程论文题目内停点火,火焰图标动态显示,进入正常工作状态,PL(比例阀最小电流):115±3mA,按上升键进入PH(比例阀最大电流):200±3mAPI(比例阀点火电流):140±3mA大宇典雅FA(气源选择,0010L液化气,0110L天然气,03交接班管理制度12L天然气),断电退出菜单。
秋天的诗句有哪些6、断开电源开关,检测完毕取下控制器,合格产品贴上客户要求的型号标签并盖上QC号流入下工序;不合格品贴上故障现象内容并作好记录,送返工维修。
