偏差处理案例

1、SummaryDescription/ 描述The product temperature sensor?in Glatt fluid bed drier cannot be calibrated before removing from the system, discrepancy was initiated according to SOP-0102619 section ?"A discrepancy must be initiated when a calibration fails or no as found readings can be taken before t

2、he sensor removed from the calibration schedule".Glatt制粒机里的产品温度传感器在从系统删除前无法做校验,根据 SOP-0102619步骤“校准失败或当仪表从校准方案中删除无法获得前校数据时,必须启动差异处理程序启动偏差.1. Deviation/ Actions /偏差行动Production staff observed the product temperature sensor was broken on maintenance teamreplaced the broken product temperature sens

3、or with a newimproved one on Work order refers toattachment TW1118464-01.生产部员工日产品温度传感器损坏,维修团队于日更换了新的经过改良的产品温度传感器.工单见附件TW1118464-01 .2. Causal Analysis /因果分析5 Why s tool was used to do the cause analysis. 5 Why' s diagram refers to attachment TW1118464- 02.用了 5 Why 's工具进行原因分析.5 Why' s示意图参

4、见附件 TW1118464-02 .1st Why the temperature sensor could not be calibrated? /为什么温度探头无法进行校验？At about 23:32 on after completion the batch of Xeldoa SH2105(end at 22:50 on ) , alarm 1017 "Product Temperature FBD(T202222)- Broken Wire" occurred, operator checked the alarm andfound that the part

5、of FBD product temperature sensor holder installed out of the chamber was broken. Electrical engineer was informed and confirmed that the sensor was broken.晚上23: 32左右在结束希罗达SH2105批次后22:50结束),Glatt系统发生报警101-7 “物料温度(T202222 )-断线,员工检查发现安装在FBD产品温度探头的腔体外局部连杆处断裂.通知了电工,电工确认该温度探头损坏.Calibration team checked t

6、he sensor and evaluated the sensor could not be calibrated as the thermocouple melting point of the sensor fell off and no output signal detected from sensor. 校验小组对探头进行了检查,评估该探头无法进行校准,由于探头热电偶熔点掉落且没有检测到信号输 出.The broken part was installed outside of the FBD chamber, picture of broken product temperatu

7、re sensor refers to attachment broken point was marked with arrow 损害的局部在FBD墙体外面,损坏的产品温度探头图见附件TW1118464-03 .箭头标注了断裂点.Above all, damage of FBD product temperature sensor caused that the sensor cannot be calibrated.综上,FBD的产品温度探头损坏导致该探头无法进行校准.2nd- Why the FBD product temperature sensor was broken? /为什么

8、FBD 温度探头被损坏？By checking the broken product temperature sensor, the thickness of temperature sensor holder broken point was about 1mm, made of 316L stainless. The end of the holder was a junction box used to install temperature transmitter, and it is a bit heavy.通过查看损坏的产品温度探头,Glatt产品温度传感器连杆的断裂处壁厚约为1毫

9、米,为316L不锈钢材质,其后部为接线盒,此接线盒用于安装温度变送器,较重.It is possible the thinner stainless of temperature sensor holder combining the heavier junction box in the end led to mechanical fatigue over time and caused the holder broke in two. After the holder broke, the junction box fell down under the gravity, pulled t

10、he temperature sensor and caused that the thermocouple melting point of the sensor fell off.可能由于温度传感器连杆的不锈钢厚度较薄,并且其后端的接线盒较重,因此使用中容易造成材质的机 械疲劳,发生断裂.连杆断裂后,接线盒由于重力作用下坠,拉扯温度探头,导致温度探头热电偶熔点 掉落.The broken temperature sensor passed the calibration before installed on the FBD, the calibration certificate ref

11、ers to TW1118464-05(TT-00142-PRO). After the discrepancy occurred, calibration team initiated the calibration decommission for it. See attachment TW1118464-05 ( TT-00142-PROCCAF- decommission).已损坏的温度探头在安装到制粒机前校准合格,校准证书见附件TW1118464-05 (TT-00142-PRO).此偏差发生后,校验小组对该探头进行了报废,详见附件TW1118464-05 (TT-00142-PRO

12、CCAF-decommission).Similar case occurred in July 2022, the deviation report number was TW1062179, the root cause was same as TW1118464. Following remediation action was defined in TW1062179 followed as post closure action TW1069248: contact Supplier, strength the temperature sensor holder, add thick

13、ness up to 2mm, and replace the wiring in the junction box in the end by 2 meter of flexible cord directly. The supplier responded it would take time to change the design of the sensor , the target completion date for this action is 月发生过类似事件,详见偏差TW1062179.偏差TW1062179制定了后续行动以关闭后行动TW1069248跟踪：联系供给商,加厚

14、温度传感器连杆壁厚至2毫米,同时后端接线盒接线方式改为直接2米软线引出.供给商回复由于改这个感应器的设计需要花一定的时间,所以该行动的预计完成日期 为.When the discrepancy (TW1118464) occurred on maintenance team just received the new sensor and the calibration was not completed yet.本偏差(TW1118464 )在日发生时,维护小组刚收到新的感应器,还没有做校验.Cause conclusion/ 原因总结The thickness of temperature

15、 sensor holder was about 1mm, made of 316L stainless. The end of the holder was a junction box used to install temperature transmitter, and it is a bit heavy. It is possible the thinner stainless of temperature sensor holder combining the heavier junction box in the end led to mechanical fatigue ove

16、r time and caused the holder broke in two. After the holder broke, the junction box fell down due to gravity, pulled the temperature sensor and caused that thethermocouplemelting point of the sensor fell off, and the calibration cannot be conducted.Glatt产品温度传感器连杆的断裂处壁厚约为1毫米,316L不锈钢材质,其后部为接线盒,此接线盒用于安

17、装温度变送器,较重.推测由于温度传感器连杆的不锈钢厚度较薄,并且其后端的接线盒较重, 因此使用中随着时间的推移容易造成材质的机械疲劳,发生断裂.连杆断裂后,接线盒由于重力作用下 坠,拉扯温度探头,导致温度探头热电偶熔点掉落,无法进行校准.Recurring discrepancy assessment/重复发生的差异的评估Timeframe: From in Trackwise go-life in Shanghai site) till( Date Closed )时间框架：查询的时间段从中gDMS在上海上线的日期)到(关闭时间)Assigned site/ 工厂:Shanghai Resp
