STATS Hot Key
The STATS hot key will allow the user to return quickly to the main Status screen. The
operator may select the Compressor Status screen or the Compressor Graphics screen
as the default main Status screen. The Quit key will always return the user to the currently
selected main Status screen. Subsequent uses of the QUIT key will toggle between the
Compressor Status screen and the Compressor Graphics screen.
Compressor Main Status Screen
The Compressor Status screen shows a numerical summary of the compressor ana-
log and state parameters. The values are continuously updated in real-time to reflect
the current state of the compressor. For example, in the figure below the current state
of the system is RUN-TRIM. The system's mode of operation is SEQ (Sequenced)
and the alarm status of the system is NORM (normal). There are also two system
functions which may be performed from this screen: Slide valve adjustment when in
Manual or Local modes and the clearing of alarms and failures.
Screw Status Screen
The following table lists the additional keys available on the screw main status screen.
