1 Malfunctions and diagnosis 故障及诊断 1.1.1 Fault messages 故障信息 Fault messages are displayed in the LED

7 segment display: 故障信息显示在

7 电子屏上: List of fault messages 故障信息列表 Display Meaning Measures - Normal operation -

1 Analog / digital transducer not functioning 模拟/数字转换无功能作用 Check connection cable, check the wiring on the weighing cell on the igs, check weighing cell 检查连接线,检查 Igs 上重力传感器的连线,检查重力传 感器

2 Data loss 数据丢失 Recalibrate igs, Re-enter the number of impulses per revolution, if necessary re-enter system setting via interface, change batteries if problems occurs repeatedly 重新校正 igs,重新输入每转脉冲数,如必要可通过接口 对系统进行重新设置,如果故障再次发生,请更换电池

3 Pinch valve does not close 截止阀未关闭 Check compressed air, check cable connections, check pinch valve rubber membrane 检查压缩空气,检查线缆连接,检查阀芯垫圈

4 Pinch valve does not open no material 截止阀未打开,无料 Check bridge formation at material inlet, release the solenoid valve locking, check the funnel weigher filling time 检查料入口处是否出现架桥现象,打开电磁阀,检查料斗 填充时间

5 Screw rotational speed missing, although extruder is turning 螺杆转速丢失,尽管挤出机仍 在运行 Check inductive proximity switch cable connection / check igs, check the switching spacing (1 -

3 mm), check the igs connection 检查感应式接近开关线缆的连接/检查 Igs,检查接近开关 间隙(1-3mm),检查 igs 连接

6 Pinch valve in manual mode 截止阀在手动模式 System switched to ?pinch valve in manual mode , initiated by switch /only for dosing stations) 系统切换到 截止阀手动模式 通过开关动作(仅在喂料 装置)

7 Weigher at bottom capacity limit 称量在底线位 Too small weight difference for weighing process (delta digit <

80), check screw speed 称量过程量变化过小(digit LED D1 illuminated ? Check cable for

24 V supply ? Check power pack ? Check fuses ? 检查 LED D1:24V 是否正常 ?LED D1 闪亮 - 检查 24V 电源线 - 检查电源模块 - 检查保险 Large differences between displayed and actual throughput, considerable throughput fluctuation 显示值与实际值出入比较大,有相当大的波动 ? Check that load cells are free and gap dimension stop screw ? Recalibrate weigher ? Check load cell ? Check setting impulse per revolution and correct if necessary ? Check inductive proximity switch switching spacing (set point: 1-3 mm) ? 检查传感器是否自由悬空,止动触点 ? 重新较称 ? 检查重力传感器 ? 如果必要检查每转脉冲设置并纠正 ? 检查感应式接近开关的间隙(设定值:1-3mm) Only half the throughput is displayed as from a certain screw rotational speed 只能显示某一时刻螺杆转速的一半值 ? Check the inductive proximity switch switching spacing ? Ensure that only one impulse is generated per mark, for this reason do not employ screws with an internal hexagon! ? Ensure that the maximum permissible frequency of

180 Hz is not exceeded ? 检查感应式接近开关的间隙 ? 确保每个记号只产生一个脉冲, 因此不建议使用内 六角螺母 ? 允许的最大频率不得超过 180Hz Material tends to form lumps 物料堆积成块 ? Increase the outlet gap of the impact cone, the fixing permits changes in

5 mm increments. ? In extreme cases the impact cone can be removed and the collection funnel fitted with a reduction piece*, however, this impairs the system accuracy. * Note: The use of a reduction piece is generally determined during the project planning phase . If required, the reduction piece can be ordered at a later date. - 增加出口处缓冲锥体的间隙, 对其进行 5mm 的调 整-万一我们需要卸掉缓冲锥体,为积料斗安置一个 缓冲片,然而,这样做会影响系统的称量精度 *备注: 使用缓冲片一般是在项目计划过程中就已经 决定了的,如果需要,在日后也同样可以定购该缓 冲片 Coarsely milled material 破碎料 See above 见上 Malfunctions Measures Shut-off unit does not open, no material, however, no fault message 阀门未打开,无料,但是无报警信息 ? Immediate help: switch off the voltage supply, the valve must open when not under tension! ? Subsequently: ? If the malfunction occurs again recalibrate the weigher ? Check the gap dimension of the stop screw, check the load cell ? 立刻操作:断开电源,无电压状态阀必须打开 ? 随后: ? 如果故障再次出现,重新校秤 ? 检查缓冲支点的间隙,检查重力传感器 igs does not transit data to the interface igs 不能传递数据到接口 Check cable connection, check node address setting 检查线缆连接,检查节点地址设置 igs does not start up, although no fault message has been transmitted and voltage supply, rotational speed recording etc. are OK igs 不能启动,尽管无报警,电源正常,螺杆转 速记录等都正常 Undertake complete reset (refer to part 1.3.4), subsequently recalibrate the unit!!! (part 1.3.2) 采取完全复位(查阅 4.3.4 部分),随后重新校准该单 元(4.3.2 部分) 1.2 Maintenance 维护 Electronic 电子部分 The igs electronic system is maintenance free. Igs 电子系统无需维护. 1.3 Service 1.3.1 Calibrating the funnel weigher with igs 通过 igs 来校秤 The igs-imis system has been calibrated at the factory. A new basic calibration becomes necessary when error message
