求助金宝报5.05 002

本院一台200s机器，自检过后一上病人就报除气压低5.05 002，观察除气压为-440至-460左右，设置为-500，除气泵占空比由62%慢慢升到75%左右后变为零，又循环反复，换过传感器，除气泵，moto阀，管道硅胶头，fm cpu 板均无果，请问高手有没遇到该故障，求指点。

FCN 5.05 002 TOO HIGH DEGASS PRESSURE                              
      General description of conditions for occurring:
      The measured degassing pressure is greater than the set degassing
      pressure for 15 minutes, and it is also greater than -500 mmHg for
      15 minutes.

      Technical description of conditions for occurring:
      (FRI(FI_DEGASSPR) > ORI(OI_DEGASS$PR$SET) + 200) and
      FRI((FI_DEGASSPR) > -5000)
      for 150 continuous seconds and after 300s, 450s, 600s, 750s and 900s.
      1 unit of FRI(FI_DEGASSPR) = 0.1mmHg.

      Some possible explanations why the error has occurred.
      * The degassing motor is broken.
      * The degassing pump is not ok.
      * The degassing pressure transducer is broken.
      * The degassing pressure amplifier is broken.
      * The A/D system is broken.
