The analog signals to the A/D converter is internally distributed into two different converters, one
with low amplification and one with high amplification, see
IEC05000296 V2 EN-US

Reasons for activation
This signal will be active when the source of the time synchronization is
lost, or when the time system has to make a time reset.
This signal will be active if the Runtime Engine failed to do some actions
with the application threads. The actions can be loading of settings or
parameters for components, changing of setting groups, loading or
unloading of application threads.
This signal will be active if the IEC 61850 stack did not succeed in some
actions like reading IEC 61850 configuration, startup, for example.
This signal will be activated when the IED has been under too heavy load
for at least 5 minutes. The operating systems background task is used for
the measurements.
This signal will be active if one or more of the application threads are not in
the state that Runtime Engine expects. The states can be CREATED,
INITIALIZED, RUNNING, for example.
This signal will generate an internal event to the internal event list if any
settings are changed.
This signal will generate an internal event to the Internal Event List if any
setting groups are changed.
This signal will generate an internal Event to the Internal Event List if the
Change Lock status is changed
This signal will be active if both the working file and the backup file are
corrupted and cannot be recovered.
This signal will be active when DNP3 detects any configuration error during
startup.
