Trends Monitoring Screen
Binary Input and Output Screen
The Trends screen displays up to 8 different values in real-time monitoring.
These value selections are customizable to meet various troubleshooting
and monitoring situations. Data is stored in internal controller memory or a
USB drive and can be easily exported and imported.
The Binary Input and Output screen displays a comprehensive view of the
status of all the inputs and outputs.
Synchroscope (Paralleling) Screen
AlarmList Screen
The AlarmList screen displays up to 16 shutdowns, warnings, and engine
messages in a color coded list. Features include an alarm summary at the
bottom of the AlarmList screen and an alarm alert on any of the metering
screens.
The Paralleling screen displays the key parameters to allow for generators
to synchronize together. The Paralleling screen provides a comprehensive
view of critical parameters to aid in easily adjusting paralleling system
settings.
History Screen
The History screen displays up to 4000 events, warnings, and shutdowns
with the reason, date, time, and critical system parameters. This extensive
event history allows for detailed analysis of reoccurring faults.
