Function description
Internal event list
16.2.3.2 Settings
The function does not have any settings available in Local HMI or Protection and Control IED
Manager (PCM600).
16.2.4 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.
A self-supervision summary can be obtained by means of the potential free alarm contact
(INTERNAL FAIL) located on the power supply module. This output relay is activated (no fault) and
deactivated (fault) by the Internal Fail signal, see
and the undervoltage detection of the PSM will deactivate the relay.
