 出现以下情况时,说明控制系统发生问题,应立即通知微机维修人员维修,同时操作工到现场进行处理。 

  (1) 经常变化的数据长时间不变,且几个数据或所有数据都不变。 
  (2) 控制分组画面中,手动自动无法切换,或手动输入数据后,一经确认,又恢复为原来的数据,修改不过来。 
  (3) 趋势图画面中,几条趋势都为直线不变。 
  (4) 监控画面中,多个数据同时波动较大。 

  判断波动数据是否为工艺上相关参数,若是相关参数则通知仪表及微机人员检查,看是否某调节系统波动引起相关参数变化,同时将相关调节系统打到手动状态,必要时到现场进行调节。如水溶液全循环装置中,尿素合成塔压力正常时为l9.67MPa,如果突然大范围波动,此时势必引起下游的中压系统、低压系统压力波动,这种情况是由于几个相关参数中某一参数波动引起其他参数变化,并不是控制系统本身故障。 

  若波动数据工艺上彼此并无直接影响,则可能为微机某卡件发生故障,立即将相关自调系统打到手动调节,必要时到现场进行调节,同时,通知微机及仪表人员检查。
