Unit: g.动态补偿：在动态称重时，如产品始终低于或高于静态重量，且偏差为一固定值，则设定该值，范围 +10000克Dynamic compensation: as dynamic weighing, if the bag weight is always lower or hig
18、her than the static weight value and the deviation is fixed, set the dynamic compensation value within the range of +10000g.动态延时：设定当前电子秤检测稳定状态的时间间隔，单位：秒Dynamic delay: set the time interval to detect the current stable state of the checkweigher. Unit: s.动态阀值：设定当前电子秤稳定状态的波动范围，如在动态延时时间内重量波动超出动态阀值，则为不稳定
19、状态。当电子秤为不稳定状态时，标定、清零、零点跟踪等动作将不成功。Dynamic threshold: set the fluctuation range of the current stable state of the checkweigher. If the fluctuating quantity exceeds the dynamic threshold within the dynamic delay, the system is unstable. That is to say those operations such as calibration, zeroing and
20、zero tracking are failed.采集次数：当复检秤开始复检称重时，采集有效重量的个数。Collection times: the number of collecting effective weight as the checkweigher begins to check weight.称重延时：当产品全部输送至电子秤上后，经过一段时间后，方可进行复检称重，以求得稳定性。单位：秒Weighing delay: when the bag was conveyed to the checkweigher, the weight can be checked only afte
21、r the weighing delay for better stability. Unit: s.零点跟踪：重量值在零点附近一定范围内时，电子秤将自动将重量值修正，逼近零点，直至为零。注意，零点跟踪一般在静态称重时用到。如零点跟踪有效，则电子清零功能失效。Zero tracking: the checkweigher will automatically correct the weight value and return to zero when the weight value is within the range near the zero point. Note: this f
22、unction is used in static weighing. If the zero tracking is active, the zeroing function will be unavailable. 跟踪幅度：零点跟踪的步伐，即每经过一段时间间隔，电子秤将重量值修正一定数值，逼近零点。如设为0，则零点跟踪功能自动被禁止。Tracking period: the checkweigher will correct the weight value and return to zero after every time interval If it is set to zero
23、, the zero tracking function will be inhibited automatically.跟踪时间：零点跟踪每次跟踪的时间间隔，如设为0，则零点跟踪功能被禁止。Tracking time: the time interval of zero tracking. If it is set to zero, the zero tracking function will be inhibited.4. 趋势图（如图3）Tendency chart (as shown in Figure 3)显示最近20袋重量，可以观察其重量变化趋势和分布情况，如图3所示As sho

28、他物体接触等）。2) Re-switch on the checkweigher before calibration. After start-up, the operation mode selection key is at stop state, the weight checking mode is “No checking”, remove the object on the checkweigher and clear anything which may have a negative effect on the weight checking (Nothing should
29、be on the checkweigher and the checkweigher is separated from other things.).3) 设定分度值：在编辑框中输入需要显示的分度值（=5）。4) Set scale division: enter the desired division value in the edit box (=5).5) 零点标定：确定电子秤静止，并处于零点（电子秤上无任何物体）后，按下按钮完成零点标定。6) Zero calibration: keep the checkweigher stationary and make it at the
30、 zero point, press key.7) 量程标定：确定电子秤静止，然后再电子秤上加载一定重量的标准砝码（建议加载满度重量砝码25kg，至少需要加载大于等于60%满度重量的砝码）后，按下按钮完成量程标定。8) Weighing range calibration: keep the checkweigher stationary and put some standard weights on it (it is recommended to put 25kg weights, at least 60 percent of the 25kg weights.), press key.
31、9) 标定结束后，一定要按下按钮，保存已经标定好的数据。10) After the calibration, press key to save your settings.11) 注意事项：标定时须将表头重新上电，先零点标定，然后再满度标定，最后保存标定。如无法标定，请检查动态阀值和动态延时等参数设置。12) Note: the system must be re-switched on before calibration. First apply the zero calibration, then weighing range calibration, at last save you

34、rt-up, the class is “Low level authority”.四注意事项 Notesl 检重秤的传感器是非常灵敏的测量器件，必须小心对待。应避免震动、挤压或过重物体掉在称重台（称重传送带）上。The load cell of the checkweigher is a very sensitive measuring instrument and therefore must be handled with care. Shocks, jamming or objects falling on the weighing table (conveying belt) mus
35、t be avoided. l 在重检秤运输过程中，称重传送带必须用螺钉螺母固定在其原位置上。The conveying belt must be fixed by the screw nut in its place during the transportation of the checkweigher.l 要称重的产品有规律地进入检重秤，即产品间距尽可能地相等，是可靠称重的前提条件。A regular infeed of the objects to be weighed, viz. product spacing shall be as regular as possible, wh
36、ich is a prerequisite for trouble-free weighing.l 请保持光电开关的清洁！因为灰尘、污迹或水气凝结在光学元件上，可能会引起故障。必要时，请用软布或棉布轻拭这些部件。Always keep the photocell clean! Dust, dirt or moisture condensation on the optical parts may cause malfunctions. If necessary, wipe these parts with a soft cloth or cotton wool tip.l 请保持重检秤的称重带
37、式传送机的清洁，因为污迹或产品留下的残余物可能会造成故障。可以使用压缩空气吹走污物或使用湿润的软布擦拭.Keep the checkweigher conveyor clean, as dirt or residual product matter may cause malfunctions. Try blowing with compressed air or wipe with a moist, soft cloth.l 若检重秤配备有皮带式传送带，请定期检查传送带。传送皮带不能接触任何防护装置或过渡板（相临传送带之间的光滑板），因为这样会导致额外的磨损和震动，对精确度可能会造成负面影响
38、。如果安装了防护装置，请检查它们是否状态良好，并且安装位置正确。尽可能快的换掉磨损的皮带。l When the checkweigher is equipped with a belt conveyor, check the conveying belt periodically. The conveying belt must not touch any guards or transition plates (glide plates between neighboring conveyors), as this would cause excessive wear and tear as
39、 well as oscillations which may have a negative effect on accuracy. If guards are fitted, check that they are in a good state and in the proper position. Replace worn belts as soon as possible.五常见问题 Frequently problems1. 上电后电机不转：Motor doesnt work after power ona) 上电后5秒种内，运行方式选择处于停止状态，5秒后应处于联动位置。如不是，
40、请手动选择，并检查联动信号线是否松脱。b) After power on, the operation mode is at stop state within 5 seconds. It should be at “Auto” position after 5 seconds. If not, manual select “Auto” and check whether the auto signal line is loosened.c) 查看变频器断路器开关是否接通，变频器控制界面的控制频率是否为零，如果是零调整控制频率。d) Check whether the switch of in
41、verter breaker is switched on. Whether the control frequency of inverter control interface is zero; if so, adjust the frequency.2. 电子秤不检重：Checkweigher doesnt check weighta) 检重方式选择开关是否处于检重位置。b) Check whether the selection switch of weighing mode is at “Weight checking” position. c) 电子秤前后光电是否正常。d) Che
42、ck whether the inlet and outlet photocells of checkweigher work well.3. 清零键失效：Clear key malfunctiona) 调整动态阀值和动态延时参数。阀值越小，动态延时越大，则电子秤越灵敏。电子秤处于动态时，无法清零。b) Adjust the dynamic threshold and dynamic delay. The smaller the threshold is, the longer the dynamic delay is.c) 零点跟踪幅度是设置为零，如不为。则零点跟踪有效，清零无效。d) Wh
43、ether the tracking period is zero. If not, the zero tracking is active, and zeroing function is unavailable.4. 仪表显示“PLC no response ”故障信息 “PLC no response” fault message showing on the checkweigher检查显示屏COM1口的插头是否松脱，BS2000E控制器是否上电。Check whether the plug of COM1 port is getting loose and whether the B
44、S2000E controller is switched on.5. 如何解决称重结果精度不稳定问题 How to solve the unstable weighing accuracy problem.a) 清除电子秤上物料，察看电子秤显示是否为零，如有误差，须按清零按钮。b) Remove the objects on the checkweigher, check whether the checkweigher shows zero. If not, press clear key .c) 检查电子秤输送带是否过松。如过松，适当调整；电子秤称重面是否水平；秤体螺丝是否有松动。d)
45、Check whether the conveying belt is too loosened. If so, adjust it. Whether the weighing table keeps level and the nuts are getting loosened.e) 电机转动是否平稳，电子秤输送速度是否与前后输送设备的输送速度一致，如不一致请适当调整变频输送速度。f) Check whether the motor runs smoothly, whether the conveying speed of checkweigher matches the neighbori
46、ng conveyors. If not, adjust the conveying speed.g) 抽检若干数量的产品，如果与实际重量偏差为某一固定值（或大致为某一固定值），可修改动态补偿参数为此固定值，在每次称重后会自动加（或减）去此值。h) If you find that the difference value between bag weight (random test) and the actual weight is a fixed value (or approximately a fixed value), set the dynamic compensation to
47、 this value. Thus the checkweigher will automatically add or subtract the value after every weighing.六运输与储藏 Transport and storage在运输与储藏检重秤时，必须遵循以下重要事项。Observe the following important items when transporting and storing the checkweigher.1. 重检秤的运输 Transportation of the checkweigher建议在检重秤到达安装地点之前，不要打开其
48、包装，因为板条箱对其有保护作用。称重传送带单独包装，以防止称重系统受到损坏。请不要施压于称重传送带上（避免冲击，请不要让任何物体掉在上面）。We recommend you not to unpack the checkweigher before arriving at the jobsite, as the crate protects it. The conveying belt shall be packaged separately to prevent the weighing system from getting damaged. Do not exert force on the conveying belt (avoid shocks; dont let any objects fall on it).如果检重秤要再一次运输过程中，称重传送带必须用螺丝固定好。只有检重秤已安放在工作地点，才能松掉固定螺丝。For another transpor
