The function does not have any parameters available in Local HMI or Protection and
Control IED Manager (PCM600).

Operation principle

The self-supervision operates continuously and includes:
• Normal micro-processor watchdog function.
• Checking of digitized measuring signals.
• Other alarms, for example hardware and time synchronization.
The SELFSUPEVLST function status can be monitored from the local HMI, from the
Event Viewer in PCM600 or from a SMS/SCS system.
Under the Diagnostics menu in the local HMI the present information from the self-
supervision function can be reviewed. The information can be found under Main
menu/Diagnostics/Internal events or Main menu/Diagnostics/IED status/
General. The information from the self-supervision function is also available in the
Event Viewer in PCM600. Both events from the Event list and the internal events are
listed 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. This
output contact is activated (where there is no fault) and deactivated (where there is a
fault) by the Internal Fail signal, see
the undervoltage detection of the PSM will deactivate the contact as well.
