#4 System Health Verification
As soon as power is applied to the CO unit (and the RT unit
if locally powered), the system automatically starts up. The
front panel indicators show the status of the system (see
Figure 3 and Table 4). If any of the LED’s is not Normal,
AktinoView can be used to determine the source of the
problem.
AktinoView main status screen shows an overview of the
system. Performance monitoring for DS3, MSPAN, and
PAIRS is available through the menu tabs. Current system
alarms (see Table 3) are displayed on the main status screen.
Alarm history and logs are available through the menu tabs.
