1、 The main motor of automatic feeding mixer cannot be started

　　故障现象：按下操作台上搅拌机启动按钮，搅拌机不启动；

　　Fault phenomenon: press the mixer start button on the console, the mixer will not start;

　　原因分析：1、空压机未启动或供气系统压力未达到；

　　Cause analysis: 1. The air compressor is not started or the air supply system pressure is not reached;

　　2、搅拌主机检修保护开关及主机上的带钥匙紧停开关未接通；

　　2. The maintenance protection switch of mixing machine and the key emergency stop switch on the main engine are not connected;

　　3、操作台上的紧停开关未复位；

　　3. The emergency stop switch on the console is not reset;

　　4、主机电源开关未接通；

　　4. The main engine power switch is not connected;

　　5、主机停止信号必须复位；

　　5. The main engine stop signal must be reset;

　　处理过程：

　　Treatment process:

　　1、检查压缩空气检测信号（大于0.4MPa的气压信号）是否送到PLC，即I8.0是否有信号。如I8.0没信号，则检查空压机压力是否大于0.4MPa，当压力达到0.4MPa以上时，I8.0还没有信号，则检查电接点压力表调整是否正常或损坏，直到I8.0有信号；

　　1. Check whether the compressed air detection signal (pressure signal greater than 0.4MPa) is sent to PLC, i.e. whether i8.0 has signal. If i8.0 has no signal, check whether the air compressor pressure is greater than 0.4MPa. When the pressure reaches above 0.4MPa, if i8.0 has no signal, check whether the adjustment of electric contact pressure gauge is normal or damaged until i8.0 has signal;
               

　　2、检查自动上料搅拌机主机检修保护开关接通信号是否送到PLC；

　　2. Check whether the switch on signal of the main machine maintenance protection switch of the automatic feeding mixer is sent to PLC;

　　3、检查操作台上的紧停开关是否复位；

　　3. Check whether the emergency stop switch on the console is reset;

　　4、检查主机电源开关是否接通；

　　4. Check whether the main engine power switch is on;

　　5、检查主机停止按扭是否复位；

　　5. Check whether the main engine stop button is reset;

　　二、在自动生产过程中，配料站骨料称好后不卸料

　　2、 In the automatic production process, the batching station does not unload the aggregate after weighing

　　故障现象：在自动生产过程中，一种或多种骨料称好在计量斗内，不卸料，系统停止运行。

　　Fault phenomenon: in the process of automatic production, one or more kinds of aggregate are weighed in the metering bucket without unloading, and the system stops running.

　　原因分析：1、待料斗关门不到位。

　　Cause analysis: 1.

　　2、称量仪表没有卸料输出信号。

　　2. The weighing instrument has no discharge output signal.

　　3、皮带机未启动。

　　3. The belt conveyor is not started.

　　4、骨料称的精称门未关到位。

　　4. The fine weighing door of aggregate scale is not closed in place.

　　5、骨料必须定义卸料顺序。

　　5. Aggregate must define the unloading sequence.

　　处理过程：1、检查待料斗斗阀门是否卡料或关门不到位，关门到位后，I6.7有信号。

　　Processing process: 1. Check whether the valve of waiting hopper is jammed or the door is not closed in place. After the valve is closed in place, i6.7 has signal.

　　2、检查骨料称量仪表是否卸料输出信号，石料1卸料I0.4，石料2卸料I0.7，砂1卸料I1.5，砂2卸料I1.2。

　　2. Check whether the aggregate weighing instrument is discharging output signal, I 0.4 for stone 1, 0.7 for stone 2, 1.5 for sand 1 and 1.2 for sand 2.

　　3、检查皮带机是否启动。

　　3. Check whether the belt conveyor is started.

　　4、检查骨料的精称门是否关门到位，石料1精称关门I8.2，石料2精称关门I8.3，砂1精称关门I8.5，砂2精称关门I8.4。

　　4. Check whether the fine weighing door of aggregate is closed in place, I 8.2 for stone 1, i8.3 for stone 2, i8.5 for sand 1 and i8.4 for sand 2.

　　三、斜皮带启不动

　　3、 The inclined belt will not start

　　故障现象：自动上料搅拌机正常启动后，按下操作台上斜皮带启动按钮，斜皮带不启动。

　　Fault phenomenon: after the automatic feeding mixer starts normally, press the start button of inclined belt on the operation console, and the inclined belt will not start.

　　原因分析：1、搅拌机未启动。

　　Cause analysis: 1. The mixer is not started.

　　2、斜皮带检修停止开关未复位。

　　2. The maintenance stop switch of inclined belt is not reset.

　　3、斜皮带机电源开关未接通。

　　3. The power switch of inclined belt conveyor is not connected.

　　4、斜皮带机停止按钮开关未复位。

　　4. The stop button switch of inclined belt conveyor is not reset.
