	The 250 MeV superconducting compact proton cyclotron of Varian Medical Systems Particle Therapy (the former ACCEL) is specially designed for the use in proton therapy systems. During medical operation typically no operator is required. Furthermore, several automated control system procedures guarantee a fast, simple, and reliable startup and beam optimization after overnight shutdown or regular service actions. We report on the automated startup procedures, automated beam centering, and automated optimization of extraction efficiency. Furthermore we present an automated beam current setting as used during medical operation by means of an electrostatic deflector located at the cyclotron center at low beam energies.
