Alarms
An SC200 supplied with a standard configuration file (see details on page 18 ) has a standard set
of alarms configured and enabled. This will be sufficient for standard dc power system
operation.
For specific alarm arrangements all SC200 alarms can be individually enabled or disabled and
are configurable.
Types of Alarms
The SC200 provides five types of alarms:
