The Common 12 kinds of Malfunctions and Solutions of Semi Automatic Auger Powder Filling Machine

Remark: The malfunctions and solutions in this article is suitable for Semi Automatic Auger Powder Filling Machine.

现象1：开机不显示。
检查电源是否正确接通。
Malfunction 1: Unit starts but display monitor is blank.
Solution: Check that machine is properly connected to correct power source.
现象2：显示器显示〖CHAO〗
原因：电子秤目前处于超载状态。
解决办法：取下秤台上的物品。在电子秤处于超载状态下，应停止各项操作。
Malfunction 2: Display monitor shows 〖CHAO〗indicates something is on the scale.
Solution: Clear scale of anything that might be on it.
现象3：显示器显示〖E1〗
原因：表明步进电机脉冲数太小。可能是没有正确进行定量标定和正确设置重量基准值，或是校验的包装物品与设置的包装重量基准值相差太大。
解决办法：用【退出】键结束。退出后步进电机脉冲数自动恢复为3000，重新正确进行定量标定和正确设置包装重量基准值，或降低步进电机的运转频率。
Malfunction 3: Display monitor shows 〖E1〗or 〖E2〗.
The number of stepping motor impulses is too low/high and must be reset.
Solution: Pressing 【exit】automatically resets the number of stepping motor impulses to 3000. Check that the value entered for calibration is correctly entered; check that the weight for each package is correctly entered; check that the packaging weight has been correctly entered for the packages you are using. Then reset quantitative calibration and package weight, or increase/decrease the stepping motor impulses.
现象4：显示器显示〖E3〗
原因：对电子秤标定时未放砝码。
解决办法：用【退出】键结束，重新进行标定操作。
Malfunction 4: Display monitor shows 〖E3〗.
Indicates that no weight was placed on scale during calibration process.
Solution: Press 【exit】to end; recalibrate scale.
现象5：光电开关反应不灵敏。
原因：可能由于光电开关感应头上灰尘太厚或灵敏度太低所致。
解决办法：擦去光电开关端面的灰尘，调高灵敏度。擦拭时请进入〖bSZ〗状态。
Malfunction 5: Photoelectric switch is unresponsive.
Solution: Wipe off dust to improve sensitivity. While wiping, please enter 〖bSZ〗status.
现象6：遮挡光电开关但不下料。
检查：遮挡光电开关时光电开关红灯亮否？测量光电开关电压是否正常（应为12V）；测量光电开关的信号线电压是否正常（被挡住时约为0V左右，不被挡时为11V左右）。
Malfunction 6: Photoelectric switch does not glow.
Using voltmeter, check and secure 12v power connection to Photoelectric switch: When switch is covered voltmeter reading is about 0v; uncovered reading is about 11v.
现象7：下料不准确
原因：物料过湿或有结块，下料螺旋转向不对，螺旋上缠有异物，搅拌器刮刀位置不当，步进电机频率不合适，操作方法有误（如接料时滴漏或是包装容器底部堵住出料口，导致物料不是自由状态进入容器）。
另外，料斗内物料料位变化太大、电网电压不稳定也会导致下料不准确。
Malfunction 7: Inaccurate blanking.
Materials are too wet or lumpy; blending screw turning in reverse direction; material may be twisted or stuck onto the screw; blender blade is incorrectly positioned; stepping motor impulse is too high/low; operation fails to function normally (e.g., there is leakage at junctions, or the bottom of a package, blocks a package mouth, which stops material from falling freely into the package.)
Blanking can also result from voltage surges and/or clumping/bunching of material in hopper.
现象8：步进电机失步
原因：可能是步进电机频率太高所致（应降低频率）；或是驱动器损坏所致（更换驱动器）；也可能物料中混有异物，使步进电机阻力增大（取出异物）。
Malfunction 8: Stepping motors are not operating synchronously.
Check stepping motor impulse amount and increase/decrease as needed; Change driver if damaged; Remove any objects in material hopper that could prevent stepping motor from operating
现象9：称量不准
原因：可能是传感器线性不一致（可多分几段进行标定）；或传感器损坏（更换传感器）。
Malfunction 9: Inaccurate weight measurements.
Check that sensors are operating normally and replace if needed
现象10：电子秤零点不稳定
原因：可能秤台放置不平稳、附近有气流，或工作环境湿度较大导致控制电路板受潮。可用电吹风的热风驱赶潮气，温度应控制在40~50℃，时间约10分钟。
Malfunction 10: Electronic scale display does not return to zero or fluctuates.
Ensure that scale is placed on dry and level surface and is away from moving air. In a high humidity environment the circuit board may become damp. Use portable hair dryer to dry the board at temperature between 40~50℃ , for 10 minutes at a time until all moisture has been removed.
现象11：下料量越来越少以至于螺旋空转不下料
原因：搅拌电机停转或传动链条脱落。
解决办法：检查电机是否损坏，张紧轮是否松动。
Malfunction 11: Blanking amounts decreasing and blending screw begins idling.
Check that blending motor is operating; check that transmission chain is in place; check that regulation wheel is securely fastened. Replace motor if needed; place transmission chain in proper position; tighten loose regulation wheel.
现象12：供料机不供料。
原因：料位开关端部粘结物料。
解决办法：切断电源，取出料位开关将粘结的物料擦拭干净。
Malfunction 12: Feeding machine stops.
Turn off power, remove level control switch and remove objects or material in contact with the level control switch.
