Next: Instrument use Up: Down Time Previous: General overview Contents
There were no faults causing more than 2 hours downtime during period 42, nor any problem that caused down time on various occasions. I here just discuss the single problem that cause the most downtime in the semester.
One of the motors of the new building drive stopped which made the telescope crash. It takes some time to reset the system and restart the telescope control system, but most of the time was actually lost due to a delay in contacting the support staff. The problem was very likely caused by the encoder cable to this motor. A new cable was purchased and has been installed.
