About GC Status
When the GC is ready to begin a run, the display screen
shows STATUS Ready for Injection. Alternately, when a
component of the GC is not ready to begin a run, the Not
Ready LED is lit on the status board. Press [Status] to see a
message explaining why the GC is not ready.
Status board
A lit LED on the status board indicates:
• The current progress of a run (Pre Run, Post Run, and
Run).
• Items that may require attention (Rate, Not Ready,
Service Due, and Run Log).
• The GC is controlled by an Agilent data system
(Remote).
• The GC is programmed for events to occur at specified
times (Clock Table).
• The GC is in gas saver mode (Gas Saver).
Alert tones
A series of warning beeps sounds before a shutdown occurs.
The GC starts with one beep. The longer the problem
persists, the more the GC beeps. After a short time the
component with the problem shuts down, the GC emits one
beep, and a brief message is displayed. For example, a series
of beeps sounds if the front inlet gas flow cannot reach
setpoint. The message Front inlet flow shutdown is briefly
displayed. The flow shuts down after 2 minutes. Press
[Off/No] to stop the beep.
