Settings
The function does not have any settings 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.
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
237. Also the software watchdog timeout and the undervoltage detection of the
PSM will deactivate the relay.
