The information can be found under Mainmenu/Diagnostics/Internal events or Main menu/Diagnostics/IED status/General. The information from the self-supervision function is also available in theEvent Viewer in PCM600. Both events from the Event list and the internal events arelisted in time consecutive order in the Event Viewer.A self-supervision summary can be obtained by means of the potential free change-over alarm contact (INTERNAL FAIL) located on the power supply module. Thisoutput contact is activated (where there is no fault) and deactivated (where there is afault) by the Internal Fail signal, see Figure 263. The software watchdog timeout andthe undervoltage detection of the PSM will deactivate the contact as well.Section 15 1MRK 511 287-UEN ABasic IED functions544Technical manual
