The engineering tasks also are in a transition phase to a scheme that minimizes the presence at the antenna. Daily engineering work at the high site for preventive and corrective maintenance can be reduced when all critical hardware systems are integrated in a remote monitoring and control system. We have started with this in 2015 and have stepwise introduced this new scheme. This required the introduction of redundancies of systems as well as the extension of sensing points and remote-control interfaces, throughout all levels in the project breakdown structure of the telescope and its auxiliary systems. We present examples of theses implemented systems and discuss the concept of redundancies. The APEX observatory is the smallest ESO site in Chile, incorporated as a department of LPO, the ESO La Silla – Paranal Observatory, within the directorate of Operations (DoO). The work presented will attempt an outline of approaches that can be applied to telescopes exposed to similar environmental conditions as well as to larger and distributed operations such as envisaged for the Paranal Observatory extended by the ELT on Cerro Armazones. |
