These are setting which are safe for the detectors. They may be not the optimal for operation. If the corresponding channel trips one should investigate what is the reason.

PDC-SCI

The HV is selected based on the energy loss in the scintillator. As of 2.2.2020 one has to look at the scope: sdaos19.acc.gsi.de (use a web browser to access it)
