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

　　故障現(xiàn)象：按下操作臺上攪拌機啟動按鈕，攪拌機不啟動；

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

　　原因分析：1、空壓機未啟動或供氣系統(tǒng)壓力未達到；

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

　　2、攪拌主機檢修保護開關(guān)及主機上的帶鑰匙緊停開關(guān)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、操作臺上的緊停開關(guān)未復(fù)位；

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

　　4、主機電源開關(guān)未接通；

　　4. The main engine power switch is not connected;

　　5、主機停止信號必須復(fù)位；

　　5. The main engine stop signal must be reset;

　　處理過程：

　　Treatment process:

　　1、檢查壓縮空氣檢測信號（大于0.4MPa的氣壓信號）是否送到PLC，即I8.0是否有信號。如I8.0沒信號，則檢查空壓機壓力是否大于0.4MPa，當壓力達到0.4MPa以上時，I8.0還沒有信號，則檢查電接點壓力表調(diào)整是否正常或損壞，直到I8.0有信號；

　　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、檢查自動上料攪拌機主機檢修保護開關(guān)接通信號是否送到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、檢查操作臺上的緊停開關(guān)是否復(fù)位；

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

　　4、檢查主機電源開關(guān)是否接通；

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

　　5、檢查主機停止按扭是否復(fù)位；

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

　　二、在自動生產(chǎn)過程中，配料站骨料稱好后不卸料

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

　　故障現(xiàn)象：在自動生產(chǎn)過程中，一種或多種骨料稱好在計量斗內(nèi)，不卸料，系統(tǒng)停止運行。

　　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、待料斗關(guān)門不到位。

　　Cause analysis: 1.

　　2、稱量儀表沒有卸料輸出信號。

　　2. The weighing instrument has no discharge output signal.

　　3、皮帶機未啟動。

　　3. The belt conveyor is not started.

　　4、骨料稱的精稱門未關(guān)到位。

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

　　5、骨料必須定義卸料順序。

　　5. Aggregate must define the unloading sequence.

　　處理過程：1、檢查待料斗斗閥門是否卡料或關(guān)門不到位，關(guān)門到位后，I6.7有信號。

　　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、檢查骨料稱量儀表是否卸料輸出信號，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、檢查皮帶機是否啟動。

　　3. Check whether the belt conveyor is started.

　　4、檢查骨料的精稱門是否關(guān)門到位，石料1精稱關(guān)門I8.2，石料2精稱關(guān)門I8.3，砂1精稱關(guān)門I8.5，砂2精稱關(guān)門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、斜皮帶啟不動

　　3、 The inclined belt will not start

　　故障現(xiàn)象：自動上料攪拌機正常啟動后，按下操作臺上斜皮帶啟動按鈕，斜皮帶不啟動。

　　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、攪拌機未啟動。

　　Cause analysis: 1. The mixer is not started.

　　2、斜皮帶檢修停止開關(guān)未復(fù)位。

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

　　3、斜皮帶機電源開關(guān)未接通。

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

　　4、斜皮帶機停止按鈕開關(guān)未復(fù)位。

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