intervention. Depending on the type of error, the HS emits
no beep or a single beep.
A series of warning beeps sounds before a flow shutdown
occurs. After a short time the component with the problem
shuts down, the HS emits one beep, and a brief message
displays. For example, a series of beeps sounds if the vial
pressurization gas flow cannot maintain setpoint. The flow
shuts down after 5 minutes. A shutdown message briefly
displays. Press [Clear] to stop any beep. Vials in the oven
continue to equilibrate, but the HS handles no additional
vials and will not perform an extraction or injection.
A continuous tone sounds if using HS carrier gas control
and if hydrogen flow is shut down or if a thermal shutdown
occurs. During a hydrogen shutdown, all HS heaters and
motors turn off.
Before resuming operations, investigate and resolve the cause of
the hydrogen shutdown. See
Troubleshooting manual for details.
If a problem occurs, a status message appears. If the
message indicates broken hardware, more information may
be available.
If the system shuts down a gas flow or the vial oven, Off will
blink on the appropriate line of the component's parameter
listing.
