We currently have a problem with the azimuth drive of the dome which is preventing operation.
We were hoping that the failure point would be the dome Az fuse, which occasionally trips. We have had help from the OT maintenance team to check the fuse.. and sadly it doesn't appear to be the culprit.
I have completed a list of possible components which could have failed causing the symptoms we are seeing; based on this list I have prepared a series of tests for the OT maintenance team to preform which should allow us to determine the cause of the fault.
Once the cause of the problem has been located we are planning to visit the site as soon as possible to perform the repair work.. We've already filled in all of our trip booking paperwork and found suppliers for the possible failed components.
