Often during plant maintenance and upgrading of system components, faults can be generated. In such a circumstance, we were contacted by AstraZeneca to assist in resolving the introduced fault at their Macclesfield plant in the UK.

After some preliminary diagnosis we were able to isolate the fault to a single field device. We attended site to correct the fault, replace damaged components and to warrant the integrity of the system as commissioned.

As in the majority of cases, seemingly insignificant actions can have far wider implications. The skill is in the fault finding to identify and resolve the root cause.
